Introduction
In the beginning there is no stability; there is fluctuation, vibration, tension without definitive resolution.
The common description of the primordial universe works through a simple metaphor: a hot soup that cools progressively, passing through successive phases like a liquid that slowly crystallizes. It is a powerful image. It captures the notion of state transition, of changing material configuration. It allows the reader to grasp intuitively that the universe was not always what it is — that there were profound transformations. However, the metaphor is simultaneously misleading, because it hides what is active in the process, reducing it to a passive sequence of waiting.
The early universe did not expect to cool down. There is no external agent slowly cooling it, nor is there any final rest to which it aspires. Every transition that has occurred — from the breaking of electro-weak symmetry to primordial nucleosynthesis, from the recombination that made the universe transparent to the consolidation of the first cosmic structures — is a material reorganisation triggered when the material compatibilities of a system exceed the form that contains it. The engine is excess, never failure. When the temperature drops abruptly in the first millisecond, it is not because the universe has failed to sustain previous symmetry — it is because the compatibilities of a maximally symmetric configuration exceed the constraints of available energy.
For this reason, the cosmological terminology that speaks of "collapses", "breaks" and "decays" requires a clause: these terms name local reorganisations of matter by excess, never original crises nor productive failures. The universe does not collapse to escape a crisis — it reorganises itself because it contains, in its present form, compatibilities that exceed that same form. Collapse is an effect, not an engine. The engine is always the excess of matter over its present configuration.
In the primordial universe, nothing is stable. No form persists long enough to settle during surgery. Fundamental forces are indistinguishable at high energies, nuclei do not form. It is a regime of radical instability — but not chaos. It is metastability: provisional equilibrium loaded with material potentials. Each phase transition precipitated new forms not because nature had a plan for them, but because at each moment the compatibilities of matter exceeded their previous configuration, forcing local reorganisations. The diversity we observe in the cold universe — the various forces, the different types of particles, the periodic table — is not the result of planned complexification. It is a contingent effect of progressive loss of symmetry due to cooling.

Axis 1 — Nothing is stable at first
1.1 Metastability as a primordial condition
The notion of metastability, already operative in previous chapters as a tool for thinking about individuation, now acquires a cosmic meaning. Metastability names a condition between two regimes: neither complete thermodynamic equilibrium (where there are no differences, where there are no processes), nor disordered chaos (where no configuration is repeated). It is a provisional balance loaded with material potentials. The early universe is the radically metastable example.
Understanding this requires simultaneously inverting two intuitions about what "stability" means. Complete thermodynamic equilibrium is not a state of maximum stability as common language suggests — it is ontological death. A system in perfect thermodynamic equilibrium reaches a configuration where the temperature is uniform everywhere, the pressure is constant, the density is identical. No potential difference persists. The molecules agitate thermally, it is true, but this agitation is merely random; no structured reorganisation can occur because there are no localized constraints that allow one region to direct compatibilities to another. A perfect crystal at absolute zero, the theoretical maximum of molecular order, is also the maximum of immobility: nothing changes because nothing can change without violating the state of minimum energy. Similarly, a system in true chaos — where no configuration is repeated, where each instant brings a new complete randomness — cannot maintain any emergent structure, because structures require that certain patterns of compatibility be consolidated over time, that there be regularities that allow accumulation. Metastability is the material interval between these two extremes: there are potential differences that allow processes, transitions, reorganisations, but these differences exist in a provisional equilibrium that can be destabilised by small fluctuations. The system is not rigid, but it is not chaotic either. It is tensioned, loaded, ready for transformation.
Material tension without resolution is precisely what Gilbert Simondon calls metastability — a concept already operative in the analysis of individuation and material rhythm. Metastability is a primordial condition, not equilibrium; matter is not a passive substance waiting for external information, it is a mesh of potentials that under certain conditions reorganises itself. The application of this concept to the primordial universe requires, however, a correction that the cosmological imposes on the philosophical.
In Simondon, the pre-individual charge functions as a generic reservoir of accumulated potential that "forces" individuation when a structural germ triggers it. Individuation is resolution: tension releases into a form, and the system approaches relative rest. The material framework that operates in the reorganisations of the primordial universe is radically different. There is no generic pre-individual charge. There are specific material configurations — temperatures, densities, symmetry constraints, energetic gradients — that in specific regimes allow specific reorganisations. The "excess" that drives change is not an accumulated reservoir awaiting resolution. It is a relational property of each configuration: the fact that in any material phase there are always more possible compatibilities than the present form can stabilise.
The consequence is decisive: when a first reorganisation occurs — when the electroweak symmetry breaks, when the plasma of quarks and gluons reconfigures into hadrons — the new form does not resolve the previous tension and returns to rest. The new form is itself loaded with excess. Each phase is a precarious balance between material constraints, each balance contains incompatibilities that the present configuration cannot stabilise simultaneously. Reorganization is not a resolution of metastability. It is the transformation of one metastability into another. The ladder of phases — of decreasing energies, of increasingly differentiated forms — does not lead to a final rest where all tension dissolves. Each step is a new way of inhabiting excess. Metastability is not a transitory state for individuation. It is the permanent condition of the material. Primordiality is not a Simondonian pre-individual awaiting individuation, but a continuous succession of reorganisations where no configuration exhausts the differences that its own constitution contains.
In the moments immediately after the Big Bang, the energy density was so high that the four fundamental interactions — gravitational, electromagnetic, strong nuclear and weak nuclear — operated as a single mode of material relationship. Above temperatures of about 100 billion Kelvin, the distinction between weak force and electromagnetic force disappeared: a single "electro-weak force" operated uniformly. This does not mean that the symmetry was perfect in the sense that nothing happened. On the contrary: it means that the configuration was of maximum symmetry, which is simultaneously maximum instability. A symmetric state is a state where no direction is privileged, where all transformations preserve the properties of the system. This implies, however, that the system contains more possible material compatibilities than its present form can stabilise.
Deepening this point requires a rigorous analysis of the concept of symmetry and potential complexity. The greater the symmetry of a system, the more operations leave its fundamental properties invariant. If a system has complete symmetry — if all directions in space are equivalent, if all transformations preserve its nature — this means that the system is potentially compatible with more material rearrangements than an asymmetric system. In a regime of maximum symmetry, many different transformations of matter leave the system in the same fundamental state — because there is no reference point, there is no privileged direction, there is no asymmetry that would break these rearrangements. By contrast, in a highly asymmetric system — where only certain rearrangements leave the configuration intact — many states of matter are sealed because they would violate the symmetry breaks that characterise it. Therefore, maximum symmetry encapsulates maximum potential complexity: it contains within itself a vast array of reorganisations that can occur without changing the fundamental "character" of the system. The primordial universe is radically unstable precisely because it has within it incomparably more material compatibilities than any subsequent form that emerges from it — not because it lacks stability in the sense of being "on the verge of collapse," but because it is so charged with possibilities that no localized configuration can realise them all simultaneously.
The background is itself dynamic; there is no stable background as such. The quantum vacuum of the early universe has irreducible zero-point energy — the minimum energy state of each quantum field is not absence, it is material configuration with measurable properties. Quantum fields vibrate everywhere, and this vibration constitutes a permanent tension without definitive resolution. This is the ontological condition of the pre-biotic and pre-symbolic regime that the primordial universe embodies: no form crystallizes because no form can resist the available energy. Everything is provisional, everything is flow. Everything is tension without a resting point.
Here the first reversal against intuition takes place: the apparent simplicity of the primordial universe — a "uniform soup" — is, in fact, the regime of maximum potential complexity. A configuration of maximum symmetry is loaded with compatibilities that exceed any localized form. The metastability here is not that of a crystal that can precipitate into multiple alternative crystalline forms — it is that of a configuration that has within it an incomparable vastness of transformational potential. No single form can accomplish them all; Therefore, the primordial universe is radically unstable. Instability comes from this excess of compatibilities and the lack of differentiation that allows localized subsistence in specific ways. It is abundance, not deprivation.
As the universe expands, the energy density decreases and the temperature drops. What is decisive, however, is that this decline creates conditions in which material compatibility no longer fits into previous configurations. The system does not collapse in search of a more "stable" or "resolved" state; it reorganises itself because the previous form becomes incompatible with the energy regime now available. In a regime of metastability, the drop in temperature acts as a new constraint that redefines the forms capable of coexisting. At high energies, a unification configuration is compatible with the system. At lower energies, this unified form would violate material constraints that now come into force with renewed force. Thus, forces that were indistinguishable become distinct. What was possible becomes impossible; what was encrypted in unrealized compatibilities precipitates into form. Maximum symmetry becomes unsustainable because the regime of material compatibilities fundamentally changes. This is where cosmological phase transitions come in.
1.2 Phase transitions as material reorganisations
A phase transition is a point where the material configuration of a system abruptly reorganises. The change from ice to water is a phase transition: above zero degrees Celsius, the crystalline configuration of ice becomes unsustainable and the system precipitates a new organisation — the fluidity of water. Now, the cosmic phase transition is not a change in aggregate state. It is material reorganisation where new structures emerge, new distinctions crystallize, new constraints materialise.
The best available theoretical framework describes the first of the great cosmological phase transitions as electro-weak symmetry breaking, occurring about a trillionth of a second after the Big Bang. The unified electro-weak interaction divides into two distinct material relationship modes: the weak force acquires mass (the carriers of the weak — the W and Z particles — gain mass and become much less penetrating), while the electromagnetic force remains massless (the photon). The microscopic mechanism that the theoretical framework of particle physics describes is the condensation of the Higgs field. In a regime of high symmetry, the Higgs field has zero mean value. As the temperature drops, the field acquires a non-zero average value throughout space, and the symmetry is spontaneously broken.
What is worth noting here is not the technical precision of the mechanism — which belongs properly to experimental particle physics — but its ontological consequence. Breakage is not failure; It is reorganisation. The maximum symmetry configuration contained compatibilities that, when the available energy drops, can no longer be simultaneously realised. The system does not "solve" a previous problem; begins to operate under a new regime of constraints. Of the two now distinct forces, both operate according to the excess of material compatibilities over the present form. The strong force — whose range of action is even smaller than the weak one — crystallizes after a second millionth of a second, when the temperature drops to values approximately one hundred billion Kelvin. Later, in an even smaller fraction of time, matter and antimatter separate, leaving a tiny surplus of matter. Each of these reorganisations, however, follows the same pattern: compatibilities that exceed the present form produce local reorganisation.
It is important to delve deeper into the Higgs mechanism to understand how an abstraction such as "symmetry breaking" actually means radical material transformation. The Higgs field is not a separate entity; It is a degree of freedom of the fabric of matter itself. Under conditions of maximum symmetry — when the temperature of the early universe is extremely high — the Higgs field vibrates uniformly around a mean value of zero. It is a symmetrical vibration, without preference, without direction. All particles coupled to the Higgs field — the carriers of the weak and electromagnetic forces, W and Z — behave as massless entities, traveling at the speed of light. Yet this symmetry is maintained only by the brutal energy of the hot regime. As the universe cools, the available energy progressively decreases, and the potential structure of the Higgs field changes character. It is no longer a uniform plain — the so-called "potential well" changes shape. In a regime of high symmetry, the field potential function is flat in the centre and high at the ends: the minimum is at zero. Below a critical temperature value — approximately 160 billion Kelvin — the well inverts, however. The minimum stops being at zero and moves to a non-zero value in any direction in the field's multidimensional space. The Higgs field is forced to "rotate" to this new minimum — not because anything forces it, but because the energetic structure of the system has changed. Once this new non-zero average value is established, the field starts to vibrate around this new configuration. And it is precisely this non-zero value of the Higgs field — this coupling with the new configuration — that gives mass to the carriers of the W and Z forces, making them heavy and short-ranged. The photon, however, remains decoupled from the new Higgs value and remains massless, remaining long-range. The radical distinction between a short-range (weak) force and a long-range (electromagnetic) force emerges not from a prior plan, but from a simple change in the energetic structure of the Higgs field under cooling. The heavy matter — the W and Z bosons — did not come from anywhere. It emerges, precipitates, and condenses in universal space precisely because the temperature drops sufficiently for the Higgs field to reorganise itself. Mass is not a fundamental property that particles "have always had"; it is a relational property that they acquire when coupled to the new regime of the Higgs field. This is the essence of excess being motor: the previous configuration of maximum symmetry was unsustainable because it contained, encrypted in its own energetic structure, an incompatibility with the energy available after cooling. Reorganization to an asymmetric configuration is not fixed defect; it is an excess of the previous configuration over the energy regime that now prevails.
Cosmic inflation is another paradigm. In a tiny fraction of the first second — about 10^-36 seconds after the start, according to inflationary models — the theory describes a quantum field called the inflaton as operating in a false vacuum state — a metastable configuration of high potential energy. This false vacuum is an energetic plain where the field is trapped, even if it is not the state of minimum energy (the true vacuum). The metastability here is radical: the field contains compatibilities that exceed its present form such that the expansion of the universe accelerates exponentially. In a period of a tiny fraction of a second, the universe expands by a factor of 10 to the power of 26 — or more. Inflation is not produced by an external force pushing the universe; it is a direct consequence of the metastable structure of the vacuum. The engine is the excess potential energy stored in the inflaton field over the present configuration.
To understand this is to reject any Hegelian reading of this process. There is no dialectical negativity here, there is no internal contradiction that demands progressive resolution in more concrete determinations. Hegelian negativity operates by describing the subjective experience of loss of form — "this is no longer what it was" — but it is not the engine of material reorganisation. The material engine is always excess: compatibilities that the present form cannot sustain, potentials that the current configuration cannot realise. When the inflaton field decays from false vacuum to true vacuum, it is not because the contradiction requires overcoming. It is because the metastable configuration contains enough energy to overcome the potential barrier, and once surpassed, the potential energy is released into thermal radiation that "reheats" the universe. Reheating allows symmetry transitions that had been "frozen" during inflation to now occur.
The reheating process is itself a material transformation of cosmological importance, although it remains one of the least observationally constrained phases of cosmology — the overall structure is robust (the inflaton dissipates energy into radiation), but the concrete coupling mechanism, the final temperature scale, and the perturbative or non-perturbative dynamics of the process remain open. The theoretical framework describes it like this: during inflation, as the inflaton field oscillates around the true vacuum, its potential energy is progressively converted into thermal radiation — photons, particles, massive heat that fills the universe. This process is brutal heating, not "cooling" in the intuitive sense. The universe, which during inflation was in an almost empty state — diluted to unimaginable proportions — is suddenly filled again with radiation energy at extreme density and colossal temperature. Inflation will have expanded the universe by a factor of 10 to the power of 26; reheating fills this vastly expanded universe with radiation at temperatures that rival the Big Bang itself. This reheating is not an isolated event but an extended process that occurs during oscillations of the inflaton field around its minimum potential. Each oscillation dissipates energy in the production of particle-antiparticle pairs, which quickly annihilate in radiation, heating the cosmic plasma. Reheating ends when the inflaton field is sufficiently damped that its oscillation energy becomes negligible compared to the radiation density of the universe. At this point, the cosmic dynamics change: the expansion stops being governed by the metastable false vacuum and starts to be governed by thermal radiation. The universe begins the regime of the so-called "hot Big Bang" — the sequence of transitions of symmetry, baryogenesis, nucleosynthesis and recombination that are described below. Without reheating, none of these reorganisations would occur — the universe would be a nearly empty vacuum, eternally expanding in cold silence. Reheating is reconnection between the inflationary regime and the regime of symmetry transitions that constitute the familiar physics of the early universe. And this reconnection is not orchestrated by any agent: it is a direct consequence of the instability of the inflaton field, of its inability to sustain the metastability that characterized it during inflation. The excess — the energy stored in the form of the false vacuum — precipitates into radiation when conditions no longer support this metastability. It is a new example of the same structure: compatibilities that exceed the present form produce local and contingent reorganisation.
The unification scales we observe are not evidence of a primordial plane of symmetry that has been "breaking" over cosmic time. They are milestones of material contingency. Each scale represents a specific point of energy — a threshold of compatibility — where conditions in the universe no longer allow two forces to function as manifestations of a single unified field. The electromagnetic and weak forces unify at 100 billion electron volts — this is a consequence of the structure of the quantum fields involved, not a revelation of a transcendent truth. The strong force unifies with the electro-weak force at around 10^16 GeV (giga-electron volts) — a scale inaccessible to present particle accelerators, but logically deducible from theory. Gravity remains distant from all other forces, unifying itself only at an absurd energy — around 10^19 GeV, the so-called Planck scale. This separation is neither an accident nor a failure of the theoretical framework. It is a fundamental material property: gravity operates according to a different dimensionality (the curvature of space-time), while the other three operate in pre-curved space-time. The unification of all four forces would require a regime where curvature and quantum fields couple coherently — a regime inaccessible to the current universe and potentially impossible in principle. What this means materially is that the forces we observe — which we consider "fundamental" — are non-unifiable in the present cosmic regime. They are, on any accessible scale, distinct operations. Not a hidden law unites them. Not even a plan subsumes them. They are modes of material relations that operate according to the specific topology of the universe in which they emerge. If the initial conditions were different, the hierarchy of scales would be different. If the structure of the Higgs field were different, the scale of electro-weak unification would be different. If the gravity coupling constant were different, the Planck scale would be different. Each of these "constants" is a material contingency — not a universal law that subsists above the contingent, but a precipitated result of the conditions that produced the universe we observe.
Here comes the fundamental difference between the operator of excess as a motor and Whitehead's philosophy, which also works with process, albeit in a radically different way. From the Whiteheadian process, the central notion is adopted that reality is not a fixed substance but an event, flow, continuous reorganisation. However, Whitehead's current argument as a fundamental atomic unit is rejected. Material reorganisation is not composed of discrete experiential occasions that follow one another. It is continuous, distributed, relational — without a central point of concrescence where a subject of experience collects his prehensions. Whitehead postulates that every entity in the universe contains some degree of experience (prehension is universal), and that every entity is an actual occasion carrying eternal objects, transcendent forms that guide it. These three notions must be rejected absolutely. Not everything relates to everything — the relationship is local, constituted by the specific material constraints of the system. There are no transcendent eternal objects: there are no forms that precede matter and guide it. And there is no God as a principle of concretion that harmonizes prehensions into a coherent whole. Reorganization is contingent precipitation with no centre, no external guarantor, no consummation in a unified experience.
The four forces that we perceive today as distinct — gravitation, electromagnetism, strong force, weak force — are not "laws" imposed from outside on inert matter. They are emergent modes of material relations, crystallizing at different times as material compatibilities exceed previous configurations. Gravity remains disunified from the other three (at least in the energy regime that the current cosmos offers), because the unifying scale of gravity is incomparably larger — the Planck scale, about 10^19 GeV — a regime inaccessible to direct observation. The strong and weak forces unify at energies of the order of 10^16 GeV — energies that are still very high for the current universe, but not impossible to approach in particle accelerators. The weak and electromagnetic forces unify at about 100 billion electron volts, a scale that the Large Hadron Collider actually touches. The point is that these scales of unification are not manifestations of a hidden plane of primordial symmetry — they are specific material constraints that emerge when previous phase compatibilities disintegrate under new conditions.
1.3 Cold matter is more differentiated than hot matter
This radically reverses the common notion that the "beginning" was simple and complexity was added progressively. Precisely the opposite happens. The early universe is the condition of maximum symmetry — all forces unified, all massive elementary particles indistinguishable at high transverse energies — and this is simultaneously maximum instability. The diversity we observe now — quarks of different flavors, different lepta, bosons of different spin — is not addition. It is the effect of progressive loss of symmetry.
A quark-gluon soup, where quarks cannot condense into stable hadrons because the temperature and energy density are too high — this is the regime of maximum uniformity. Protons, neutrons, helium nuclei, lithium nuclei — these structures materialise when the temperature drops, when the available energy can no longer keep the quarks free in a plasma. Atoms — structures with a nucleus orbited by electrons — emerge when the temperature drops even further, when the energy can no longer ionize these electromagnetic couplings. Molecules, crystals, complex chemical systems — each is a post-cooling effect. The progression is not from simple to complex: it is from symmetrical to asymmetrical, from indistinct to differentiated.
Examining this cascade in more detail reveals the mechanism by which differentiation is a pure effect of cooling. In the early universe, microseconds after the Big Bang, the temperature was so high that no hadronic structures could exist. Quarks and gluons floated freely in a soup of plasma, constantly colliding, producing and destroying each other. At a temperature of approximately one hundred billion Kelvin — approximately one microsecond after onset — the energy density drops sufficiently that the quarks begin to confine themselves into composite structures: protons (combination of two up quarks and one down quark) and neutrons (combination of one up quark and two down quarks) are formed. This change is not gradual — it is abrupt. Above the critical temperature, quarks remain free. Below it, they immediately confine themselves. This is the phenomenon of quark confinement, and represents a break in fundamental symmetry: the strong nuclear force, which operated uniformly on all particles at high energies, starts to operate differently at low energies, forcing aggregation. There is no "discovery" of a new law. There is simply a regime shift where the same set of material interactions produces radically different configurations.
Moments after this confinement of quarks — between microseconds and a few seconds — primordial nucleosynthesis occurs. Protons and neutrons collide and fuse into nuclei: deuterium (one proton plus one neutron), tritium (one proton plus two neutrons), helium-3 (two protons plus one neutron), helium-4 (two protons plus two neutrons), and small amounts of lithium-7 and beryllium. This is the fundamental truth: primordial nucleosynthesis does not "create" new elements in the sense of producing them where there were none before. It precipitates local stabilities in nuclear interactions as available energy decreases. An isolated proton and neutron cannot remain together at very high temperatures because the photons are energetic enough to separate them. Below a specific temperature — a few billion Kelvin — thermal energy is no longer sufficient to break nuclear coupling. The proton and neutron precipitate in a bound configuration. This is neither selection nor optimization — it is simple freezing of a material compatibility that, at higher energies, remained unrealized.
Later, approximately 380,000 years after the Big Bang, when the universe has cooled to just a few thousand Kelvin, recombination occurs. Electrons and nuclei, which until this point existed separately in an ionized plasma, combine to form neutral atoms. Again, the mechanics are identical: at high energies, photons constantly separate electrons from nuclei. The electromagnetic attraction between the negative charge of the electron and the positive charge of the nucleus is superimposed by the thermal energy of the photons. Below a critical temperature — the ionization potential of hydrogen is around 13.6 electron volts, corresponding to a temperature of approximately 150,000 Kelvin — the photons, however, lose sufficient energy. Electromagnetic attraction prevails. Electrons and nuclei precipitate into bound states. And with this change comes a radical transformation: the universe goes from opaque to transparent. Before recombination, the universe was a hot soup where photons were constantly scattered by free electrons — a regime of complete opacity, impossible to "see" through electromagnetic radiation. Afterwards, the radiation can travel freely through space. The diversity of atomic structures — neutral hydrogen, neutral helium-4, minuscule amounts of lithium — emerges not as an addition, but as a consequence of different nuclei having different ionization potentials. Heavier nuclei (helium, lithium) require higher energies to ionize, crystallizing at slightly different temperatures. The table of elements that began to form in primordial nucleosynthesis — just quarks in initial confinement, then protons and neutrons, then some light nuclei — now extends to neutral atoms.
The true diversity of elements — the periodic table that we know today, with 92 stable natural elements — does not emerge, however, in the primordial universe. It emerges later, in much colder environments, mainly inside stars. This is crucial: stellar nucleosynthesis is a cooling effect on a different scale. In the core of a massive star, the temperature is so high that nuclei of lithium, beryllium and boron — the elements missing from primordial nucleosynthesis because they disintegrate easily — can be temporarily created and fused into heavier nuclei. Carbon, nitrogen, oxygen, iron — all precipitate in stellar cores through cascade nuclear reactions where each reaction occurs when temperature and pressure reach specific values. When a massive star explodes in a supernova, these elements disperse into cosmic space, enriching the gas clouds that eventually form new stars and planets. The chemical diversity that we observe in the current universe — on our planet, in organisms, in all matter that can be analyzed — is the result of this cascade of nucleosyntheses: primordial (producing light elements), stellar (producing intermediate elements up to iron), and supernova (through extreme nuclear reactions, producing very heavy elements such as gold, uranium, plutonium). None of these syntheses "create" new matter. They redistribute elementary constituents as energy constraints change.
This does not mean that cold matter is "more evolved" or "more advanced" than hot matter. Evolutionary terminology is deeply misleading here, because it assumes that there is a direction, a target, an intentionality in the process. There is not. It just means that cosmic cooling has produced cascading material differentiation. The early universe potentially contained all the elements, all the structures, all the configurations that we observe today — not as crystallized forms, however, but as material compatibilities that high energy kept unrealized. As available energy decreased, at different times and on different scales, these compatibilities precipitated into locally stable structures and organisations. The periodic table — the diversity of chemical elements that make up all the matter we can directly observe — is multilayered cosmic archaeology. Each element indicates the specific condition in which it precipitated, the particular energy regime where the nuclear compatibilities of its constituents were realised. Hydrogen and helium-4 originate from primordial nucleosynthesis, crystallized microseconds after the Big Bang. Helium-3, deuterium and lithium-7 are also from this same era, but in minuscule amounts, because their nuclear compatibilities required very narrow temperature windows to crystallize. Elements from carbon to iron are mostly archeology from stellar cores, synthesized only when the first generations of stars burned nuclear fuel. The heavier elements — lead, gold, uranium — require even more extreme energies, only available in supernovae and neutron star collisions, so they emerge very late in cosmic history. No ontological hierarchy subsists here. No "order" guides the process. Only the material physics of nuclear interactions, operating according to the energetic constraints of each cosmic epoch, structurally producing new compounds each time nuclear compatibilities change. Diversity is not a planned construction. It is contingent sedimentation of nuclear instabilities under progressive cooling.
1.4 No stage, no plan, no observer
The transitions we describe occurred without any of the structures we might assume are necessary for a process to be "real." There was no stage on which the events unfolded. Space-time is not a neutral container in which processes of material reorganisation take place. Space is relationship — unfolding of material differences that simultaneously constitute it and are constituted by it. The distance between two points in the primordial universe is not a geometric dimension of a pre-existing space — it is a material difference. As matter reorganises itself, its material relationships change, and with them the topology of space itself. General relativity has already demonstrated this inseparability: the curvature of spacetime is determined by the distribution of energy and matter, and the distribution of energy and matter is constrained by the curvature of spacetime. There are no two sides — geometry and matter — that interact from separate positions. There is immanent co-determination: space does not exist before the matter that constitutes it, nor does matter exist outside the space it generates. Cosmic inflation is not the expansion of a universe into a previous empty space. It is the generation of spatial relations through material reorganisation — space emerges from matter, not matter emerges in space. The "stage" is a retrospective fiction that the inscriptional regime projects to make the narrative of transitions intelligible: without a prior stage, intelligibility demands that we think of space itself as a product of the reorganisations that seem to occur within it.
There was no plan. No intention, no intelligence, no design directed the phase transitions. Spontaneous symmetry breaking — the mechanism that governs fundamental transitions — is a process where the system transitions from a high symmetry configuration to a lower symmetry configuration, not because a force directs it, but because the symmetric configuration has become unstable under new energy constraints. The system "chooses" a break direction, but the choice is not deliberation — it is material contingency determined by random fluctuations in the transition point. Material compatibilities operated according to the constraints of available energy. The fact that electro-weak symmetry breaking occurred instead of an alternative regime is pure material contingency — one possible outcome among many, precipitated by the specific historical conditions of the early universe. There is no a priori reason why the weak and electromagnetic forces should unify at 100 billion electron volts instead of any other energy. It is the structure of the Higgs field, its specific potential shape, that establishes this point. The shape of the Higgs field, however, is itself contingency — it could be different in possible universes with different material constraints.
There was no observer. The recombination — which occurred approximately 380,000 years after the Big Bang, when the universe cooled enough for electrons to bind to nuclei forming neutral atoms — produced the first major transition in the regime of optical transparency. Before recombination, photons were constantly scattered by free electrons, the universe was opaque to electromagnetic radiation. Afterwards, the universe became transparent, and photons could travel freely. This radiation released by recombination — the cosmic microwave background radiation, now observable as the CMB — is the first radiative conformation stable enough to be captured, much later, by an inscription regime. No observers were, however, present. No registrant recorded the event. Matter reorganised itself according to its own material constraints, and the result was a radioactive configuration that, much later, human instruments would be able to detect.
To insist is to persist in the variation without being reduced to a foundation. The primordial universe is exactly this: persistence of material reorganisations, continuous flow of compatibilities transformed into new forms, without any foundation that supports the whole, without any stable centre that organises it. Each phase transition is itself a reaffirmation that no configuration is final. Each cooling precipitates new differences. If all reorganisations operated by excess, without a plan and without an observer — what is the status of what precipitated it?
Axis 2 — Material reorganisations due to excess
There are critical moments where reality has reorganised itself through excess, precipitating configurations that still allow us to exist. Each of these moments is radical contingency — it could have been otherwise. None follow a plan.
What distinguishes a reorganisation due to excess from a collapse due to failure? This is the line that divides understanding. In a failure, the system loses capacity — it runs out, wastes away, succumbs because something was missing. In an excess reorganisation, the system reorganises itself because the material compatibilities present exceed the form it contains. The engine is not deprivation; It is overflow. The way it precipitates is not salvation from a deficit; it is a contingent remainder of a local abundance. It is this inversion — engine not in lack but in excess — that makes it possible to understand cosmological phase transitions not as repaired catastrophes, but as structural reorganisations of matter operating according to their own logic.
2.1 Baryogenesis: radical contingency
The universe contains matter, not antimatter. This seems like a trivial observation of the present state of the cosmos, but it is the most profound enigma facing modern cosmology. The reason is simple and devastating: particle physics predicts that, in the Big Bang, matter and antimatter should have been created in absolutely equal quantities, in perfect symmetry. If that were the case, they would annihilate each other — each proton would encounter an antiproton, each electron a positron, and the two would disappear in pure gamma rays. The same fate for all particles and their antiparticles. The result would just be radiation. Nothing would exist. No galaxy, no stars, no life. And yet, here we are. There is matter. There is asymmetry. This is the fundamental question that baryogenesis must answer.
In 1967, physicist Andrei Sakharov identified three conditions necessary for a matter-antimatter asymmetry to emerge from the initial state of symmetry. The first condition is the violation of the baryonic number — that is, that there are processes where the total number of baryons (protons and neutrons) is not conserved. Without this violation, no reaction can produce more baryons than antibaryons, regardless of any other circumstances. The second condition is the violation of the C and CP symmetries — that neither the isolated charge inversion nor the conjugated charge and parity inversion preserve the dynamics of the fundamental interactions. If C and CP were exactly symmetric, any process favoring matter would be exactly offset by a symmetric process favoring antimatter, and no net asymmetry would emerge. The third condition is that the universe is not in thermal equilibrium, but in a situation of radical imbalance — that cosmic expansion creates irreversible flows of energy and density, preventing reverse reactions from erasing the asymmetry generated. This third condition is, in a way, the most fundamental: without imbalance, no asymmetry can settle and persist. The review literature formulates these conditions as necessary; whether they are also sufficient remains an open question, dependent on the concrete mechanism of baryogenesis — and several competing mechanisms (leptogenesis, electroweak baryogenesis, GUT decay) remain observationally indistinguishable.
All these conditions occurred. In the early universe, during the phase called baryogenesis (which occurs about a hundredth of a second after the Big Bang), the temperature was approximately one hundred billion Kelvin — hot enough to create particle-antiparticle pairs at a dizzying rate. Under these extreme conditions, weak interactions operated at maximum strength, and systematically violated C and CP — as guaranteed by the Standard Model structure of fundamental interactions. The universe, at the same time, was radically out of thermal equilibrium, because expansion was accelerating, creating a unidirectional flow of energy and matter. And so, in this context of symmetry violation and radical imbalance, matter-antimatter asymmetry precipitated.
The ratio that emerged is astonishingly accurate: for every billion matter-antimatter pairs that annihilated each other, a single particle of matter survived. This means that, across the entire observable universe, the asymmetry was one part in a billion. Nothing more, nothing less. The margin for variation is microscopic — and it is critical. If the asymmetry had been one part per hundred billion — just ten times smaller — the universe would be practically pure radiation, with matter so rarefied that galaxies would never form. If it had been one part per hundred million — just ten times greater — the density of matter would have been sufficient for the universe to instantly collapse into a primordial black hole, leaving no complex structure. The range in which life, as we know it, is possible is a razor's edge between these two catastrophes.
The engine of this asymmetry is not faulty. This is absolutely crucial: there is no deficit that asymmetry can repair, there is no crisis that baryogenesis can solve. The engine is excess. The initial configuration of the universe — perfect symmetry between matter and antimatter — is a metastable configuration under present conditions of symmetry violation, thermal imbalance, and accelerated expansion rate. This instability is not a defect that anyone could have prevented, nor is it a disturbance of an ideal state. It is structural property of matter under those specific conditions. Matter, at those energies and densities, exceeds its symmetric configuration — local compatibilities exceed present form. When it exceeds, it reorganises itself. The result is asymmetry.
Everything that exists — galaxies, stars, planets, molecules, the atoms in the reader's body — descends from this infinitesimal surplus. Each galaxy is made of baryons (protons and neutrons) that escaped annihilation. Every star is the collapse of hydrogen that has been preserved. Each life is a chemical reaction of elements that began as primordial nuclei. There is no chance involved in the sense of accident or fortuitous luck. There is radical instability and contingent precipitation, as local material compatibilities rearrange themselves. The article did not aim for this result; the universe reorganised itself according to the logic of operating excess. Baryogenesis cannot be thought of as a failure that symmetry suffered — it is a reorganisation that matter carried out. This reorganisation precipitated material conformities that persist — the proportions of helium, carbon, oxygen in the cores of galaxies — and that the current inscriptional regime can capture as cosmological data.
The asymmetry that precipitated is the least energetically favored state relative to the initial state of perfect symmetry — in any other universe with slightly different parameters, the asymmetry would be different (perhaps smaller, perhaps larger, perhaps absent entirely). Here it is what it is because the physical conditions determine it — because the violation of C, the violation of CP, the thermal imbalance operate as they do. Not because something aimed at this. Not because a previous intention planned it.
The question that remains is that of reasons. Why did an asymmetry emerge and not zero? Why one in a billion and not ten, or a hundred? The classic formulation of this requirement comes from Leibniz: why is there something rather than nothing? The question presupposes that existence lacks justification, that for any fact there must be a sufficient reason to explain it — not just the conditions that made it possible, but the reason why it was actualised and not another possibility. Applied to baryogenesis, this would mean: is there a sufficient reason for the set of parameters (magnitude of CP violation, expansion rate, ratio of baryons to photon) that precipitated this specific result? Is there a reason that makes the observed asymmetry necessary?
The Leibnizian principle of sufficient reason is a profound bet: that all facticity of reality responds to a justifying structure, that facts do not just happen, but are rationalizable based on something that makes them intelligible and necessary. God, in Leibniz, is precisely this operator: the mind that compared all possible worlds and chose the best. Without this selector, the question of sufficient reason becomes a gap: why this and not something else?
Baryogenesis shows something different. The parameters that determined the asymmetry — the exact magnitude of the CP symmetry violation, the cooling rate of the early universe, the initial baryon density — are themselves contingent. They have no sufficient reason to justify them. They are what they are because material reorganisation precipitated them that way, not because a previous reason demanded them. This is not ignorance — it is not saying "we don't yet know what the reason is." It is an ontological statement: the structure of reality is such that contingency is constitutive. Some facts are crude. They have material conditions (Sakharov's conditions), they do not have a reason that makes them necessary.
What distinguishes a condition from a sufficient reason is decisive: a condition is a material configuration whose presence allows a result to occur; a sufficient reason is that which makes that result necessary, which eliminates contingency, which justifies why it had to be this way and not otherwise. Baryogenesis has conditions. There is not enough reason. No prior structure — no cosmic intention, no deeper fundamental parameter, no maximizing intelligence — was there to require this to occur. Asymmetry emerged in operation. The parameters that precipitated it are gross. And it is in this material brutality that contingency shows itself as a constituent, not a deficiency.
The Leibnizian alternative — that an optimal God chose this among all possible worlds — is a theological supplement that the material process does not need. Baryogenesis operated without a selector. Operated without optimizer. It operated without there being a comparison between possible worlds, because possible worlds are symbolic fictions constructed retroactively by reason, not entities that preceded the operation of the real. The Leibnizian principle of sufficient reason projects onto the material a structure that is characteristic only of the symbolic — that of rational choice between alternatives. Matter does not choose. Reorganize yourself. And in this reorganisation, contingency is not a failure of intelligibility. It is the same texture as the real thing.
2.2 Primordial nucleosynthesis: form without an inscriber
Twenty minutes after the Big Bang. Baryogenesis is complete. The early universe is a hot, dense soup of quarks, gluons, electrons, neutrinos, photons — particles at energies so high that they remain unbound. The temperature is approximately one billion Kelvin. The density is 38 orders of magnitude above the present value (a thirty-eight with 37 zeros before). In this hell of radiation and free particles, the process called primordial nucleosynthesis begins — the formation of the first light nuclei that will make up most of the matter in the universe.
The mechanism is simple but demanding. The temperature begins to fall — progressively, inexorably — because the universe expands. As the temperature drops, it gradually becomes possible for protons and neutrons to remain bound together in a coherent structure. The barrier is electrostatic repulsion — the Coulomb force that pushes protons against each other. Overcoming this barrier requires extremely high temperature and high density. Both conditions exist in the early universe — but only temporarily. The time window in which nucleosynthesis can occur is extraordinarily narrow. The universe is continually cooling. The density is continually decreasing. There are perhaps twenty minutes — cosmically speaking, nothing — for all nucleosynthesis to be completed before conditions become too cold.
Within this dizzying interval, material reorganisation unfolds. A proton captures a neutron, forming deuterium — a heavy hydrogen nucleus. Two deuterons collide, fuse, form helium-3. Helium-3 captures another neutron, producing helium-4 — the most stable isotope. Traces of lithium-7 and beryllium form through subsequent reactions. Afterwards, the temperature drops below the critical threshold. The fusion stops. Nuclear processes practically stop. The universe is left with a composition that endures: approximately ninety percent uncombined hydrogen (single protons), approximately twenty-five percent helium-4, and minimal proportions of helium-3, lithium, and other light isotopes. This proportion — seventy-five percent hydrogen, twenty-five percent helium — is the precipitate that primordial nucleosynthesis leaves behind.
The contingency of this proportion is total. If the temperature had dropped even a single degree more at any point in the nuclear window, the reactions would have stopped sooner, radically altering the final outcome. If the neutron were just a thousandth heavier than it is — a microscopic change — it would have completely decayed into protons before it had a chance to combine with them, and there would have been no helium formed. Without primordial helium, no further stellar nucleosynthesis would produce carbon, oxygen, iron, gold. If the strong force (the interaction that binds quarks into protons and neutrons) were just two percent weaker, deuterium would be impossible — protons and neutrons would never be able to stay bound long enough to fuse. No helium. No complex matter later.
Each of these contingencies is absolute. There is no tolerance. There is no margin for error. If any parameter were slightly different, the composition of the universe would be entirely different. Maybe just hydrogen. Maybe no nucleosynthesis at all. Maybe something completely different. And yet, here it is: seventy-five percent hydrogen, twenty-five percent helium. Not because someone aimed for this. Not because a higher law prescribed it. It turns out that those were the real conditions — that was the real cooling, that was the real density, those were the real parameters operating.
It is absolutely crucial to understand what primordial nucleosynthesis is in relation to the enrollment regime. Nucleosynthesis is not a phenomenon in the philosophical sense — it is not something that manifests itself, that offers itself to observation, that leaves a legible contemporary conformity. No instruments were there to observe. No conscience paid attention. No measurement operations occurred. Primordial nucleosynthesis occurred as pure material difference — as reorganisation of nuclear configurations that remained entirely in the regime prior to any inscription, prior to any legibility. The real operated. Nuclei were formed. The proportions precipitated. All this happened in a regime where no inscriber was present, where matter was reorganised according to its own logic of local compatibility.
What we know today about primordial nucleosynthesis does not come from observing its occurrence — it is impossible. It comes from theoretical nuclear physics calculations, modeling the reactions that should occur, and comparing those calculations with an observed result — the cosmic abundances of helium, lithium and deuterium that we can measure now, 13.8 billion years later. The fit between theory and observation is extraordinary — the abundance of primordial helium-4 we observe in distant galaxies matches exactly what primordial nucleosynthesis predicts. This confirms that the calculations are correct. What this means, however, is that the reorganisation itself — the molecular and nuclear process of combination and decay that produced these abundances — is pre-symbolic and pre-observational, already finished, already incorporated into the results we can measure. Nucleosynthesis left no mark — it left proportions, material differences that persist as present conformities. It is the current inscription regime that transforms them into cosmological data, into marks in the technical sense. The reorganisation itself remains pre-symbolic, prior to any inscription.
2.3 Recombination and the first radiative compliance
Three hundred and eighty thousand years after the Big Bang — a tiny instant on a cosmological scale, but an eternity of transformation on a material scale. The temperature dropped to approximately three thousand Kelvin. It is the surface temperature of a cold, old star. In this energy, the material regime changes radically. The matter of the universe is still predominantly plasma — a gas of positively charged nuclei and negatively charged electrons, separated by the energy of electromagnetic repulsion. At this specific temperature, the energy becomes, however, insufficient to maintain the separation. The energy barrier that kept electrons and nuclei apart collapses. The electrons can finally be captured in orbits linked to the nuclei.
The process called recombination begins. Protons pick up electrons, combine, form neutral hydrogen atoms. Helium nuclei — made of two protons and two neutrons — pick up electrons, forming neutral helium atoms. Lithium and beryllium cores do the same. In a few hundred years — cosmically speaking, an insignificant duration — most of the baryonic matter in the universe goes from a highly energetic, ionized state to a neutral, bound state. The plasma disappears. Atoms emerge.
A material consequence immediately follows: the opacity of the universe disappears. While the universe was plasma, electromagnetic radiation constantly interacted with free electrons — it was absorbed, dispersed, and redispersed continually. Radiation could not travel long distances without being interacted with. The universe was therefore opaque — impervious to radiation. When electrons are captured in bound states in atoms, however, they no longer interact strongly with photons. Radiation becomes released. It propagates freely throughout the universe. Each photon travels in a straight line, without colliding. The universe becomes transparent.
This is the cosmic microwave background — the Cosmic Microwave Background (CMB). It is the radiation that was released at this moment of recombination, 13.8 billion years ago. It traveled, without stopping, in a straight line, through the expanse of the entire universe. It permeates the present universe. It is here now — in every volume of space, there are photons of this radiation, a relic of recombination. In 1964, radio astronomers Arno Penzias and Robert Wilson accidentally detected it while cleaning a communications radio antenna. They detected a background noise that they couldn't explain — constant, isotropic, coming from all directions. Further investigation showed: it was not interference. It was primordial radiation. The recombination had precipitated a radiative conformity that permeated the entire universe.
The point is: what exactly does it mean to call this radiative compliance? Discipline here is strict, not allowing confusion. What is real is the process of material reorganisation — the transition from plasma to neutral atoms. This process occurred without an observer, without inscription, without intention, without a legibility regime that would capture it. Electrons in free states reorganised into bound states. Nuclei captured electrons. Atoms formed. This is not "inscription" in the ontological sense — it is not an operation that leaves a documentable mark. It is pure material reorganisation, the operation of the real in a regime prior to any inscription. What is real is this process, indifferent to any possibility of being read by a future instrument.
The concrete — the level at which physics operates, the level of the legible mark — is what our inscriptional regime captures now: radiation arriving at the microwave detectors, with a well-defined temperature of approximately 2.7 Kelvin, with a spectral distribution of energy that exactly matches the blackbody spectrum, with tiny temperature fluctuations (anisotropies) that the Planck probe mapped with extraordinary precision — variations of one part in a hundred thousand between different regions of the sky. These observations, this data, this pattern of cosmological fluctuations — all of this is a material mark that the legibility regime of physics can read, decode, understand. The CMB is concrete — it is a material difference that was captured in an inscriptional regime that transformed it into legibility.
A common conceptual error is to think that the CMB is a "trace" of the early universe — as if it were stored evidence, an archive, a record left for future reference. It is not like that. The CMB is not a vestige in the sense that it is preserved. It is the current present — radiation that exists now, that was released 13.8 billion years ago but that hasn't stopped traveling, hasn't stopped existing, hasn't been stored in a cosmic archive awaiting discovery. What makes the CMB special is that our inscriptional regime — telescopes, satellites, spectral analysis — can read the material conformity that recombination has precipitated in it. The temperature pattern, the spectral composition, the density anisotropies — all of this is material information that can be extracted. The matter that recombined left its signature materialized in radiation — a signature that the present inscriptional regime can decode as data. This is exactly the problem that the real/concrete tripartition clarifies, however: reading is an operation of the concrete. The real that preceded — the pure reorganisation of plasma into atoms — remains a prior regime, not captured by inscription, not transformed into legibility either before or during the recombination. The real operated. The brand precipitated. The brand, however, is an operation that only gained legibility when a future registration regime managed to capture it.
Recombination has no subscriber. There is no plan that guides you. There is no intention that directs it. It is contingent precipitation of a material instability: when the temperature drops below a specific threshold (about 3000 K), the ionic configuration of the universe becomes energetically unfavorable — the excess energy required to keep electrons free exceeds the available energy. The system reorganises itself. The electrons bond. The proportion of neutral atoms that form, the speed at which the transition occurs, the pattern of small density fluctuations that remain — these are all direct effects of actual conditions, not of prior orientation. The reorganisation is pure. The mark we read today is the material remains of this reorganisation, transformed into concrete — made legible — by the physics of electromagnetic radiation and the instruments that can detect it.
2.4 Dark matter and observational surplus of the cosmos
The first question that emerges when counting the matter in the universe is elementary: how much is there? If we counted only the matter we can directly observe — the stars that emit visible light, the hot gas that emits X-ray radiation in galaxy clusters, electromagnetic radiation of all frequencies — we would reach a disturbing conclusion. The matter we can see makes up approximately five percent of the total mass-energy density of the universe. The rest is invisible. Approximately twenty-seven percent of the mass-energy of the universe is matter that does not emit electromagnetic radiation detectable by any instrument, does not absorb light, or reflects light. It exists only through the gravitational manifestation it exerts. It exists only because it weighs. This is what astronomers call dark matter.
The evidence for dark matter accumulates in multiple independent directions, creating a convergence that makes dismissal impossible. We start with the rotation curves of galaxies. Vera Rubin and Kent Ford, observing galaxies in the 1970s, made a surprising discovery: galaxies rotated too quickly at their edges. The orbital speed of stars at great distances from the galactic centre was so high that, according to celestial mechanics, they should simply escape — they should be ejected into intergalactic space, leaving only the nucleus of each galaxy. And yet, the stars remained in orbit. The only possible explanation: there must be additional mass — invisible — that provided extra gravity. A mass that did not emit light, but that curved space in order to keep the stars gravitationally bound. The rotation curves only make sense if we wrap dark matter halos around each galaxy — halos much larger and much more massive than the visible matter.
Galaxy clusters present the same problem on an even larger scale. A cluster is a structure where hundreds or thousands of galaxies orbit a common centre. We can measure the speed at which galaxies move away from each other, the dispersion of speeds. We can compare this to the mass we see — the integrated light from all the galaxies in the cluster. Once again, the discrepancy is glaring: the visible mass is completely insufficient to keep the cluster gravitationally cohesive. Galaxies should be dispersing. They should be disconnecting from each other. And yet, they remain connected. Conclusion: dark matter. Lots of dark matter — maybe five, ten, twenty times more mass in dark matter than in visible matter.
A third line of evidence comes from a phenomenon called gravitational lensing. When light from a distant object (a remote galaxy, for example) passes through a region of space with high gravitational density (a massive cluster of galaxies), that region bends space in such a way that it bends the path of the light — just as an optical lens bends rays of light. The pattern of this deviation allows astronomers to measure the total mass of the region — visible and invisible. Detailed maps of clusters, constructed through gravitational lensing observations, reveal that dark matter forms massive structures: concentric halos around galaxies, filaments that link clusters in a cosmic web, condensations where dark matter participates in the coalescence that produces new galaxies. Dark matter is not just present; is dominant. Structures the universe.
The most precisely quantitative confirmation comes from the Planck probe and its microscopic observation of the cosmic background radiation. The CMB carries in its fluctuation pattern the signature of the acoustic oscillations that occurred in the primordial plasma — these oscillations reflect the total character of the density of matter when the universe was still plasma. Planck mapped these oscillations with extraordinary precision. Subsequent calculations allow cosmologists to determine the global composition of the universe with remarkable accuracy: twenty-seven percent dark matter, five percent baryonic matter, sixty-eight percent dark energy (different phenomenon). This is not speculation. It is not extrapolation. It is an exact calculation, extracted from the precise pattern of fluctuations observed in the CMB. The margin of error is a few percent. The conclusion is robust.
One fundamental question remains: what is dark matter? The honest answer is: we don't know. Theoretical candidates abound. WIMPs — Weakly Interacting Massive Particles — massive particles that barely interact with ordinary matter, which would pass through a human body without leaving any trace. Axions — hypothetical very light particles predicted by particle physics theories. Primordial dark matter — small black holes formed in the early moments of the Big Bang. Each candidate has testable predictions. None have yet been definitively discovered. The Euclid mission, launched in 2023, will make a three-dimensional map of a billion galaxies, using gravitational lensing to constrain the distribution and properties of dark matter. Uncertainty about the physical identity of dark matter does not, however, make its existence any less certain. The evidence is multiple, independent, convergent — no one working in observational cosmology doubts that dark matter exists.
Here is the critical ontological point: matter does not coincide with that which emits light. The matter does not coincide with what the present registration regime can identify and characterise molecularly. The concept of matter, operated within the framework that this book develops, necessarily includes sectors whose observational phenotypic is null or reduced — sectors that only manifest themselves through gravitational effects. The matter exists before any inscription regime was able to read its detailed composition. Dark matter is living and measurable proof that the observable — what we can see, measure, decompose — is not a complete mark of the real material.
This is not to say that dark matter is "unknowable" in the Kantian sense of inaccessible to any form of knowledge. This means that it exceeds the present legibility regime. Dark matter actively participates in cosmic reorganisation — it structures clusters, sustains galactic halos, influences the distribution of common baryonic matter. Its influence is measurable through gravitational effects. Its existence is necessary — without it, cosmological equations cannot be closed, observations have no coherence. Its constituents remain undetermined — and perhaps will remain so indefinitely if no elementary particles of dark matter are discovered in the laboratory. Perhaps dark matter is an emergent phenomenon of collective properties of large-scale spacetime, not a corpuscular entity. This does not matter for the ontological question. Matter is matter — registered or not registered, legible or not legible under this regime.
The consequence must be disambiguated: the concept of matter must be broadened to encompass everything that participates in the gravitational dynamics of the universe, regardless of whether it emits, absorbs or reflects electromagnetic radiation. Ordinary baryonic matter — protons, neutrons, electrons, and the atoms and molecules they form — is only a fifth of the total matter in the universe. Everything else — the vast majority — is dark matter. The cosmic reorganisation therefore takes place in two languages simultaneously: one that we can read in detail (baryonic matter — composition, molecular structure, thermal history), another that we are still learning to decipher and whose identity remains obscure (dark matter — distribution, gravitational effects, unknown composition). Both operate according to the same logic of reorganisation by excess. Both produce contingent forms — which could have been different under slightly different parameters. None of them follow a plan. None are the fulfillment of a previous plan.
2.5 What precipitates
Each reorganisation by excess produces something that persists. Baryogenesis precipitates a cosmic asymmetry. Nucleosynthesis precipitates proportions of nuclei. The recombination precipitates a radiative configuration that the future inscriptional regime will be able to capture. Dark matter precipitates gravitational structures that drive the coalescence of baryonic matter. How does persistence emerge from processes that, in principle, should dissipate all energy into uniform heat? The answer involves understanding that dissipation is not the enemy of the organisation — it is, paradoxically, its condition.
Ilya Prigogine demonstrated that complex, ordered structures can emerge spontaneously in open systems kept far from thermodynamic equilibrium, precisely because these systems continually dissipate energy into the environment. A living cell, a convection column in heated fluid, a chemical diffusion pattern — none of these structures violate the laws of thermodynamics because none of them are closed. They remain ordered precisely because they continually export entropy. Prigogine's gain was decisive: it showed that irreversibility is not just degradation of the system, it is a condition of possibility for the organisation to emerge without an external plan, without a designer, without a prior teleological law.
This insight is operative. It allows us to think about how, in a baryogenesis far from the equilibrium of extreme temperatures, the asymmetry between matter and antimatter crystallizes not as the realisation of a cosmic ideal, but as a material result of the dissipation of initial symmetry. It allows us to think about how nucleosynthesis produces specific proportions of helium and hydrogen, not because it aims for that proportion, but because the material conditions of temperature and density constrain which reactions dissipate energy in a stable way. It allows us to think about how recombination precipitates neutral atoms in a process where the free energy to maintain the plasma disappeared — it was exported in the form of photons that began to travel freely through the universe.
The cosmic structure differs, however, in one crucial aspect from any dissipative system that Prigogine studied. The early universe is not an open system that exchanges energy with an external environment. There is no outside environment. The excess that precipitates is not regulated by an external and continuous source of energy that feeds the organisation — it is the very exhaustion of the material conditions that made the previous form viable. Nucleosynthesis does not occur because the universe is coupled to an external reservoir of energy that maintains the reaction; It occurs because the temperature drops sufficiently so that nuclear energy is no longer dominant in particle reactions. Asymmetry does not emerge because the system continually reorganises itself according to an external gradient; emerges because the initial symmetry, under conditions of increasingly lower energy, becomes materially unsustainable.
Therefore, the engine of precipitation is not dissipation — it is excess, the incompatibility between the present form and the material conditions that support it. Dissipation is a consequence, not an agent. It is what results when excess forces reorganisation and the energy that maintained the previous form is released in degrees of freedom that can no longer be collected. Each dispersed degree of freedom makes the return materially inaccessible. It makes the reorganisation irreversible, not because statistical entropy has increased — although it does — but because the very material process that sustained the previous form has been transformed into a multiplicity of modes that do not converge again to the previous configuration. Irreversibility is not a statistical property of a vast ensemble; it is a constitutive property of each event: once the electron was released in recombination, once the photon was emitted, once the energy was reorganised according to new compatibilities, the entire material field changed its topology. Return would require not just reversal of probabilities, but reconfiguration of the entire material field together.
The universe does not rearrange itself to create form. It reorganises itself as local material compatibilities require it — and when reorganising itself, it precipitates. What precipitates is functional remainder: a configuration that condenses and temporarily stabilises previous excesses, which persists as long as the conditions that produced it remain. A helium nucleus is the remainder of nucleosynthesis — what freezes excess nuclear energy. An atom is the remainder of recombination — what captures the electrons that were free. A halo of dark matter is the remnant of cosmic coalescence — what gravitationally stabilises the distribution of matter. None is the realisation of a previous ideal. They are contingent material states that remain as long as conditions sustain them.
The universe does not aim at form; the universe reorganises itself — and in reorganising itself, it precipitates. What precipitates is the rest. And the rest is everything that persists as long as conditions support it.
Axis 3 — The way I rest
3.1 Against Plato, against Hegel
The time-honored answer to the question "where does form come from?" was offered by Plato: form precedes matter. Forms are eternal, immutable, and matter only "participates" in them — receives an impression from an already present mold. The problem is structural: if form is eternal and precedes matter, how can the relationship between the two be explained? Platonic "participation" requires an intermediary between the intelligible and the material domain — intermediary who is himself form or matter, replicating the problem ad infinitum. Plato interrupts the return by ontological decree, not by argument. Cosmological phase transitions impose the opposite: form does not precede matter. It emerges contingently from material reorganisations when present compatibilities exceed the current configuration. There is no transcendent domain of eternal Forms. There is matter in constant reorganisation, precipitating configurations according to its local compatibility logic. The form-matter relationship is not a mystery to be solved by transcendent intermediaries — it is a material process to be described in terms of energy, compatibility, precipitation. Primordial nucleosynthesis dissolves Platonism in the bud: the helium-4 form does not participate in an eternal Helium Form — it precipitates when protons and neutrons, under constraints of extreme temperature and density, find nuclear bonding compatibilities that allow for stable configurations. If the temperature had been slightly different, the resulting proportions would have been different. Form is contingent in relation to the material conditions that allow it, not necessary in relation to an intelligible domain that grounds it. The Platonic third-man — the need for an intermediary between Form and the copy that generates infinite regress — dissolves when the separate domain is eliminated: if form is an emergent material configuration, there are no two planes to mediate between.
The problem that Plato leaves unresolved requires, however, an intermediate step — a reconfiguration of the relationship between form and matter itself that does not project form into a timeless beyond, but also does not give up the need to think about how matter comes to be configured. Aristotle, the first philosopher to seriously question the theory of Forms, offered a conceptual instrument that dominated Western thought for two millennia: the distinction between matter as potentiality (dynamis) and form as actuality (energeia). Matter is not, in his system, that which passively participates in a transcendent form. It is what can become, the reservoir of possible orientations. Form is not the ultimate reality that matter copies or imitates. It is that in which matter realises itself, the actualization of an immanent tendency.
This represents a decisive gain over Plato. The form stops floating in a separate dimension, it stops being a copy of a copy. Form and matter become inseparable: there is no form without being embodied in a material, there is no matter without some configuration. The sublunary world is not a degradation of an eternal world. It is the unique scene where potentiality and actuality meet and realise each other. Aristotle naturalizes form. It is no longer a question of mystical participation, it is a question of an immanent process.
The price of this gain is the introduction of teleology as the foundation of the process. For Aristotle, potentiality is not indifferent. It has an intrinsic orientation. Matter pregnant with potential cannot realise any form: it has its own form, a telos that attracts it. The acorn becomes oak because its material has the form of oak as its own telos. The four Aristotelian causes — material, formal, efficient and final — are woven into a structure where the final cause (the telos, the "for what?") is precisely what guides the process. The efficient cause (what moves) only works because it works towards a form that is rightfully proper to the material in question.
It is precisely at this point that the system incurs a projection that cannot resist confrontation with what the cosmological phase transitions show. Aristotle's potentiality is oriented. It has a destiny. When the acorn germinates and becomes oak, it updates what was already inscribed in its essential nature. The shape of the oak is not just a configuration that emerges through external conditions; it is the realisation of an essence that matter carried as its own telos. This is what answers the question "What is this?" — form is the response to ti esti, to what a thing is deep down.
Now, Aristotelian thought faces a strict limit when confronted with the material reorganisation that characterises phase transitions. If form is essential, if it definitively responds to "What is?", then the change in form is a change in essence, in one's own nature. What emerges from a phase transition is not the actualization of a potentiality that the system had as its immanent destiny. It is a contingent reconfiguration that persists as long as energy conditions support it. A helium nucleus is not "essentially" helium in a way that refers to a prior telos. It is a configuration that is precipitated when the excess of energy over the previous form forces the matter to reorganise itself according to the compatibilities available in that energy regime. The helium shape wasn't waiting to be updated. It is not a response from a ti esti that potentially subsists in undifferentiated nuclear matter.
This implies a rigorous inversion of Aristotelian potentiality. It is not the material that is passive and the form that is active, real, causing. It is the material excess — the tension between the available energy and the way in which it is distributed — that is active and driving. The form that emerges is not the telos, the consummation of a destiny. It is the residual, that which persists as long as conditions allow. When these conditions change, the form changes too, not because matter rebels against its telos, because the excess that kept it in that configuration reorganises itself in another way. Hence the question "What is this?" do not have the last answer referring to the form. It is possible to describe the configuration that now persists, without obtaining the essence. Only the form of a residual is obtained, depending on conditions that will change.
Hegel offered an alternative: not transcendent eternity but immanent becoming. The engine would be dialectical negativity — the internal contradiction that demands resolution, producing becoming and progressively more concrete determinations. Hegel avoids infinite regress because contradiction is self-driving. This solution, however, contains an inversion that needs to be undone. The ontological operator is not negativity. Negativity describes the experience of loss of form — the dissolution of the previous configuration. Describing is not producing. The core-collapse supernova makes this visible. A massive star maintains hydrostatic balance between compressive gravity and radiation pressure generated by nuclear fusion. As fusion consumes fuel and the iron core — energetically unfavorable to fusion — builds up, the pressure drops. Hegel would describe this as a contradiction that demands overcoming: the negation of the negation. What happens materially is different. The contraction of the core releases an absurd amount of gravitational energy — energy that rivals all the fusion accumulated over a billion years. The material rebounds against the practically incompressible core. The explosion occurs because matter contains, in its present configuration, compatibilities that the existing form cannot sustain. No contradictions resolved. No synthesis. Just material excess reorganising itself contingently, precipitating functional remainder: a shock wave, a remnant, nuclei of heavy elements dispersed throughout space. Excess produces; the failure describes. Never the other way around. The lesson is general: every attempt to derive material production from conceptual negativity — contradiction, lack, insufficiency — inverts the ontological order. What operates is material excess; what describes the experience of transformation is symbolic negativity. Confusing description with operation is the error that sustains both Platonic idealism and Hegelian dialectics.
3.2 Archeology of remains
The periodic table is not a taxonomy of essences — it is an archive of radical contingencies frozen in atomic mass. Each element is functional remainder: what precipitated when specific nuclear conditions allowed it. Hydrogen and helium are remnants of primordial nucleosynthesis, crystallized in the first few minutes. Elements from carbon to iron are remnants of stellar cores. The heaviest elements — gold, uranium — require energies only available in supernovae and neutron star collisions. No ontological hierarchy subsists. No element is "more real" than another. They are all precipitated contingents of conditions that could have been different.
Hoyle's resonance makes the radicality of this contingency visible. Carbon-12 is formed by the triple-alpha reaction: helium-4 fuses with beryllium-8 — an extremely unstable nucleus that decays in 10^-16 seconds. Conventional nuclear mechanics predicted negligible amounts of carbon. Fred Hoyle, deducing backwards from the observed abundances, predicted the existence of a carbon-12-specific resonance at 7.65 MeV above the ground state — an energetic configuration that dramatically amplifies the effective section of the reaction. The resonance was later confirmed experimentally. If it did not exist, or if it were displaced in energy by 0.5%, there wouldn't be carbon in significant quantities. Without carbon, there is no organic chemistry, there is no biology as we know it. The fact that we live in a universe with carbon does not mean that the universe was designed to contain us. It means that the nuclear properties of carbon-12 are such that its formation is possible within this framework of specific physical laws — and this framework is contingency, not necessity.
It is necessary, however, to name the problem that this observation appears to generate and, at the same time, reject the way in which it is usually posed. The fact that multiple physical parameters — the nuclear resonance of carbon, the intensity of the strong force, the cosmological constant, the mass ratio of the proton and electron — appear to be "tuned" to allow for complex structures has been called fine-tuning. If any of these values differed even slightly, no stars would form, no chemistry would be possible, no life would exist. The argument has acquired two canonical responses, both problematic.
The first is the design argument: the parameters were chosen by an intelligence to allow the complex to emerge. This position transfers the contingency without resolving it. Why did the designer choose these values? Why does this designer exist? It is discovered that the argument introduced into the real a symbolic category — the notion of choice, optimization, intention — that only makes sense in a significant economy. It collapses the pre-symbolic into the symbolic and offers as a solution the infinite recursion of questions of the same type.
The second is the multiverse answer: our universe is one among many, each with distinct parameters; We observe ours because we exist in it — anthropogenic selection. Here the opposite occurs: ontological proliferation without empirical constraints. The "set of universes" is a symbolic construction without material anchoring — a mathematical operator presented as a population of entities. The material question ("why these values?") becomes a statistical question ("what is the probability of this universe?"). A statistic requires a population, and we do not have access to any population of universes. The argument turns ignorance into an explanation.
What is established here is a relocation. Fine-tuning is not a problem to solve, it is a description to place appropriately. Hoyle resonance is a real material property. Cosmological parameters are real constraints that the material process has precipitated. They are not "adjusted" because adjustment presupposes an adjusting agent. They were not "selected" because selection presupposes considered alternatives. They are what they are: brute, contingent material facts, without underlying necessity. The question "why these values?" belongs to the same family as "why is there something instead of nothing?" — presupposes that contingency requires justification. Contingency does not require justification. It is the texture of reality.
What is refused is the interpretative framework that turns the observation into an anomaly. The "problem" of fine-tuning exists solely within the assumption that non-contingency is the default state, that geometric necessity is the background, and that any deviation constitutes a sign of intelligence or selection. This assumption is not neutral: it is itself a symbolic projection. Material reality does not work under the principle of necessity — it works under the principle of difference and local constraint. The parameters we observed are conformities that this particular process precipitated. No comparison with "alternative universes" is pertinent because these universes do not exist — they are not data, they are not observable, they are nothing but symbolic figures of a possible economy that never came to fruition. The fact that we live in a specific material configuration does not require explanation by deviation from necessity. It only needs a precise description — the one offered here: constitutive contingency, without background.
Energy conservation is absolute in each reorganisation. No phase transition creates or destroys energy; each material reconfiguration redistributes what already exists — potential kinetics, mass radiation, binding energy released or absorbed. The first principle of thermodynamics does not admit exceptions. Shape — the configuration that energy takes under specific constraints — is not conserved. A helium nucleus persists for a billion years; a virtual fluctuation exists during a Planck time. Both are states that energy goes through, ways of distributing itself under material conditions. Remove the extreme temperature, change the constraint holding the nucleus together, and the configuration dissolves. The energy remains. The form disappears.
This disjunction between conservation of energy and transience of form is the physical foundation of the thesis that crosses this axis: form as remainder. What persists in reality is not the current configuration, it is the ability to reorganise itself as constraints change. The helium nucleus is not an essence that exists in its own right; it is a way for energy to group together when protons and neutrons encounter sufficiently stable binding conditions. That grouping is contingent. Other densities, other temperatures, another environment — and the cluster dissolves. The default is an accident of the configuration, not a fundamental attribute.
The consequence dissolves essentialism at its root. If every form is a way of distributing energy under constraints that are themselves material and contingent, then no configuration has privileged ontological status. The question "what is this?" cannot be answered by pointing to the current form, because that form depends on conditions that can cease. What could be called the "essence" of any material configuration is not the form it now presents, it is the set of constraints under which energy organises itself — and these constraints are also transient, contingent and reconfigurable. A molecular cloud is as real and as temporary as the star that may emerge from it; Both are forms that matter takes. None are more fundamental.
The conservation of energy guarantees continuity: the real persists, because the energy that constitutes it persists. The transience of form ensures that reality is never reduced to any particular configuration. This is the precise meaning of "rest": the form that precipitates is the way in which the real persists through reorganisation — not an essence, not a privileged moment, just a point of material balance between constraints that never cease to change.
Every form is, therefore, a configuration that lasts as long as the compatibility of forces allows, and that ceases when this compatibility ends. Duration is not a measure of ontological reality: a star that persists for a billion years is as much a functional remains as an unstable particle that lasts for a thousandth of a second. Both are material configurations that remain as long as local equilibrium is maintained. And every form contains within itself the conditions of its own overcoming — not because a transcendent force destroys it from outside, but because the matter that constitutes it is capable of reorganising itself when the compatibilities that sustain it change. The excess is permanent. No configuration completely fixes material compatibilities.
How, then, can we think about the persistence of a configuration without transforming it into essence, without reducing it to an archive and without dissolving it in mere succession? If all form is remainder — contingent, dated, transitory — what does it mean to say that something "begins"? Nucleosynthesis is not the "beginning" of nuclear matter; it is reorganisation, folding of matter into a different regime of stability. Recombination is not the "beginning" of atomicity; it is precipitation of a configuration that conditions have made possible. No absolute novelty, no cut where non-being becomes — just successive foldings where rearrangements by excess produce forms that are always remnants of previous compatibilities. The tension between material continuity and formal discontinuity demands that the concept of "origin" be refounded — not as an absolute zero point, but as a specific type of fold.
Every form is an old collapse that has not yet learned to fall again.
