The Universe Is Not an Object
The statement "the universe is not an object" appears not as a poetic aphorism or a rhetorical provocation, but as the rigorous conclusion of a confrontation between traditional ontology and the material findings of contemporary cosmology. It constitutes a radical thesis, as it attacks one of the most persistent pillars of Western thought: the tendency to hypostatize, to convert reality, or its entirety, into a thing (a objetum, something thrown before the subject) endowed with defining properties. To understand the scope of this denial, it is first necessary to unfold what is meant by "object" from a demanding philosophical perspective. An object, in its paradigmatic condition, presents itself as an entity that has determinable limits (whether spatial or conceptual), that exhibits an internal unity that confers coherence to its constituent elements, and that maintains a stable identity across a significant temporal interval, allowing it to be reidentified as the same. It is this triad - delimitation, unity, identity - that founds objectuality, from the Aristotelian conception of ousia as the ultimate substrate of properties, up to modern philosophies of substance.
The universe, as a total field of existence and a condition of possibility for all particular objects, refuses to satisfy any of these criteria. Its non-objectifiability is, therefore, of a different order: it is not that it is an object too vast or complex to be grasped; is that the category of "object" itself proves ontologically inadequate to describe it. Firstly, it is not delimitable. Any attempt to draw an ultimate limit to the cosmos comes up against a logical and material paradox: this limit, to be real, would have to be a border between something and something else. But the universe, by definition, encompasses everything that physically exists. To postulate a "beyond" would be to postulate something that, by hypothesis, would not belong to the universe - an exercise that can be logically conceived, but that lacks any material referent and that contradicts the very notion of physical totality. A limit only makes sense for something within the universe. The universe itself is not "inside" anything. Secondly, it is not unifiable by a single internal principle. Its reality is fractured by irreconcilable scales in its current theoretical description: the laws that govern the quantum domain seem strange to those that structure gravitation on a large scale. The search for a "Theory of Everything" is the contemporary expression of the desire for unification, but its undecidedness, and the so-called "hierarchy problem" (the disconcerting discrepancy between the scale of forces), suggest that this unification may be a regulative ideal, not an ontological description. Finally, it is not identical to itself over time. Cosmology tells a story of irreversible evolution: from an initial state of extreme density and temperature, through successive phase transitions (the decoupling of fundamental forces, the formation of particles, nucleosynthesis, the formation of structures), to the current era, dominated by mysterious dark energy. Today's universe is radically different from the universe a second after the Big Bang, not just in content but in the very nature of the dominant interactions. There is no static essence that persists; there is a continuous process of transformation.
Consequently, the cosmos cannot be conceived as a closed totality, a finite sum of parts that could be circumscribed, weighed, or named as a unitary substance. This concept belongs to the imaginary of the world as a finite and hierarchical order. What contemporary physics reveals is the figure of an open field of emerging relationships and configurations. This field does not have an exterior that contains it (it is not a container) nor a substantial interior that unifies it (it is not a homogeneous content). Its "totality" is, paradoxically, that of a radical openness, of a play of forces and material arrangements without a final architectural principle.
This cardinal distinction between local object and total field far transcends a simple difference in magnitude or scale. It is a difference of an ontological nature. Let us consider a paradigmatic local object, such as a galaxy. It has a defined causal horizon: a region of spacetime within which events can influence each other within the lifetime of the galaxy. It has gravitational cohesion: its stars, gas and dark matter are linked by mutual gravitational attraction, forming an identifiable structure that resists scattering. And it has a dynamic but traceable identity over billions of years, allowing us to speak of the "Andromeda Galaxy" as a persistent entity despite its internal evolution. The galaxy is, therefore, an emerging effect of local relationships (gravitational, mainly) that acquires relative autonomy and stability.
The universe, taken in its entirety, does not share these emerging properties of local objectivity. Let us analyze the concept of horizon. The cosmological horizon - often confused with a "limit of the universe" - is actually a deeply relative concept. It defines the maximum sphere from which light has been able to travel to a specific observer (us on Earth) since the beginning of the observable universe. This is a limit to our ability to receive information, not a physical barrier to the cosmos. The crucial point is this: each point in spacetime has its own cosmological horizon. An observer in a distant galaxy would have a different horizon than ours, centered on their position. Therefore, there is no o horizon of the universe, an absolute and universal limit. There is an infinite multiplicity of horizons, each dependent on the position and momentum of the observer. This relativization is a fatal blow to the idea of an object-universe delimited by a single boundary.
Likewise, the question of the overall shape or topology of the universe remains open, and this openness is symptomatic. Cosmological models based on the General Theory of Relativity allow for various spatial geometries: closed (like a 3D sphere), open (like a saddle) or flat (Euclidean). High-precision observations, notably of the cosmic microwave background radiation by the Planck collaboration (2018), indicate that the geometry of our observable universe is extremely close to flat. However, and this is a philosophically and physically crucial point, a flat geometry does not necessarily imply an infinite universe. It can correspond to an infinite and simply connected space, but it can also correspond to a finite and multi-connected topology, such as a three-dimensional torus. In the latter case, the universe would be finite but without borders: traveling in one direction, one would eventually return to the starting point, but at no point would one encounter a "wall". Determining the global topology escapes, in principle, our observations, as it would require seeing repetitive patterns on scales larger than the cosmological horizon. Thus, the question "Is the universe finite or infinite?" may not have a definitive observational answer. This constitutive indeterminacy is not a failure of our knowledge, but a reflection of the fact that "totality" is causally inaccessible to us.
The large-scale structure of the cosmos, mapped by galactic censuses, reveals a vast "cosmic web" of filaments and voids. This configuration can be understood, in the framework adopted here, as the result of local functional couplings that temporarily stabilize, without implying any global unification. The accelerated expansion shows that the total relational field does not converge to a unitary final state: it reorganises itself into regimes that do not project a telos.
Thinking of the universe as an object therefore constitutes a categorical error: it projects onto the total relational condition categories valid only for local configurations. Here it is not a question of reiterating the delimitation - unification - identity triad, but of marking the decisive passage between knowledge and ontology: physics provides observational limits (relative horizons, possible topologies), and it is from these material constraints that the inapplicability of objectuality to the relational total is ontologically inferred. The categories that define an object - internal limits, unifying principle, persistent identity - do not apply to the material field in process.
Genealogy of Cosmic Totalization: The Long Shadow of the Object
The difficulty in thinking about the universe beyond the category of object has deep roots in the history of Western philosophy and science. Tracing a genealogy of this desire for totalization is not an exercise in erudition, but a way of understanding the resistance of the paradigm and identifying the moments of rupture that foreshadow its contemporary dissolution.
In the beginnings of Greek thought, tension was already present. Anaximander of Miletus (6th century BC), in an audacious conceptual leap, proposed the ápeiron - the Unlimited, the Indeterminate - as arché, the principle and originating element of all things (witnessed in fragments DK 12 A9, A11). THE ápeiron it is not an object in the sense of a material element like Thales' water or air. It is rather a principle of indeterminacy, an infinite field or matrix from which pairs of opposites (hot/cold, dry/wet) separate to generate the ordered world. There is a powerful intuition here: the ultimate foundation is not a "thing", but that which escapes determination. However, even Anaximander did not completely escape the logic of substance. THE ápeiron, although indeterminate, still functions as an ontological foundation from which the multiple derives and to which it returns. It is the "eternal and immortal nature" from which all things are generated. In the theoretical framework defended here, this intuition is radicalized by the refusal of any notion of foundation or primordial substance. There is no principle prior to relationships; the real is constituted by the ongoing relationships themselves. The universe is not the emanation of a transcendent source; it is the immanent network of interactions without an external ground.
The thought of Plato and, above all, Aristotle, consolidated the model of the cosmos as a perfect, finite and ordered object. Node Timeu, Plato presents a cosmogony where a Demiurge (Divine Artificer) models chaotic matter by contemplating the eternal Forms, creating the cosmos as a "single, visible living thing, which contains within itself all the living things that are related to it by nature" (30c-d). The Platonic cosmos is, therefore, a total, unified, ordered and intelligible organism, a reflection of the perfect world of Ideas. Aristotle provided the most influential physical and metaphysical framework for this view. In his treaties Physical e Of Heaven, argued categorically for the finiteness of the universe. For Aristotle, the infinite (apeiron) cannot exist "in act", only "in potential" as a process that is never completed (for example, the potentially infinite division of a line). An infinite body would be impossible, since a body, by definition, has a surface and limit. Consequently, the Aristotelian universe is a finite and perfect sphere. At its center, motionless, is the Earth; on its periphery, the sphere of fixed stars, whose daily circular movement defines time. This universe therefore has a perfectly defined interior and exterior. The "natural place" of each element (earth, water, air, fire, ether) defines a cosmic hierarchy. It is the archetype of the object-universe: bounded, unified by natural teleology, and essentially identical to itself in its eternal cyclical movement. This vision, fused with Ptolemy's geocentric astronomical system, dominated the Western imagination for more than a millennium and a half, shaping Christian theology and the medieval view of the world as a finite and meaningful order.
The Scientific Revolution of the 16th and 17th centuries shifted the center, but did not immediately dispel the aspiration for objectified totalization. Copernicus (1543), by placing the Sun at the center, maintained a finite and spherical universe, merely reorganising its hierarchy. The real conceptual break came with Giordano Bruno. In your dialogue Of the Infinite, Universe and Worlds (1584), Bruno defended a radical view: the universe is infinite in extent and infinite in the number of worlds. For Bruno, infinity was a necessary consequence of God's infinite goodness and power. In an infinite universe, there is no absolute center or periphery; any point is, in some sense, central. This view dissolves the possibility of objectifying the cosmos: an infinite whole cannot be circumscribed, measured or treated as a singular entity with limits. Bruno's infinity was still metaphysical and speculative, without the support of mathematical physics, but it already pointed to a rudimentary cosmological principle and an acentric universe. His conviction by the Inquisition symbolizes the clash between the vision of the world as a finite and ordered object and the vision of the universe as an open and unlimited field.
It was Immanuel Kant who, in Critique of Pure Reason (1781/1787), faced the problem of cosmic totalization at the heart of theoretical reason itself, identifying it as a source of inevitable metaphysical illusion. His famous antinomies of pure reason place reason before pairs of contradictory propositions, both apparently demonstrable. The First Antinomy concerns precisely the entirety of the world: the Thesis states that "The world has a beginning in time and is also limited in space"; the Antithesis states that "The world has no beginning and no limits in space; it is infinite in both time and space." Kant argues that both proofs are fallacious because they make the same mistake: they treat the "world" (the totality of phenomena) as if it were a thing in itself, a given object that can be known in its entirety. However, the world is never given to us as a complete whole; it is given only in the infinite succession of our representations. Therefore, the question about its finiteness or infinity is undecidable from the point of view of theoretical knowledge. The Kantian solution is brilliant: the world-universe is not an object of experience, but an Idea of Reason. It is a regulatory concept that impels us to always seek conditions that are earlier in time and more distant in space, without us ever being able to reach an unconditioned condition. Kant thus had an acute diagnosis of the impossibility of knowing the universe as a total empirical object. However, the perspective adopted here disagrees with the transcendental location of the problem. The impossibility of objectifying the universe does not derive primarily from a limit a priori of our cognitive faculty (the reason that extends beyond understanding), but of a constitutive and material characteristic of reality itself. Non-totalization is not a defect in our knowledge (a "transcendental illusion"), but a positive property of being. The universe exceeds totalization not because our reason is finite, but because its very relational and processual nature is intrinsically open-ended and non-substantial.
Hegel's absolute idealism represents the most ambitious attempt to restore totalization, but now as a dynamic and self-conscious process. In your Science of Logic by you Phenomenology of Spirit, the Absolute is not a static substance, but a Subject-Totality that determines itself through the dialectical process. The famous formula "the real is rational; the rational is real" encapsulates this vision: the history of the cosmos and spirit is the history of Reason (the Absolute) coming into itself, becoming aware of itself through its mediations and contradictions. In this teleological vision, finitude and infinity are moments overcome in a superior synthesis. The perspective defended here is directly opposed to this metaphysics. There is no Absolute, there is no cosmic Subject, there is no internal teleology that guides the material process. The universe of contemporary cosmology is not a "Spirit that alienates and reconciles itself"; it is a multiplicity of local configurations, whose history does not follow a dialectic aimed at an end of self-recognition, but obeys a thermodynamic arrow (increase in entropy) and an expansive dynamic without purpose. The "contradiction" between the finite (the observable) and the infinite (the total potential) is not a dialectical contradiction to be overcome by a synthesis, but a relational datum that characterizes the very structure of reality.
Contemporary Cosmology: The Material Dissolution of Objectification
The 20th century saw not another revision of the image of the object-universe, but its material and conceptual dissolution through the development of cosmology as a precise physical science. This dissolution occurred in several acts, each one eroding one of the pillars of objectuality.
The first act was the abandonment of the static universe. Albert Einstein (1917), when applying his newly created Theory of General Relativity to the cosmos as a whole, sought a static, finite and closed model - a three-dimensional sphere - that would satisfy his prejudice for an immutable universe. This model was an ultimate, albeit sophisticated, attempt at objectification: a perfect, determined geometric whole. However, Einstein himself had to introduce the "cosmological constant" to keep the model static, a solution he would later consider his "biggest mistake". The static solution was unstable, as shown by Alexander Friedmann (1922), who derived the equations for an expanding or contracting dynamic universe. Observational evidence for this dynamic came with Edwin Hubble (1929), who demonstrated that distant galaxies move away from us at speeds proportional to their distances. The universe was not a static container; it was an expanding process. The idea of a cosmic object with a fixed size fell apart.
The second act was the formulation of the cosmological principle and the Friedmann-Lemaître-Robertson-Walker (FLRW) metric. The cosmological principle, supported by increasingly broad observations, states that on sufficiently large scales (above about 300 million light years), the universe is homogeneous (the same everywhere) and isotropic (the same in all directions). This means there is no privileged position, no special center or periphery. The FLRW metric is the geometric description of such an expanding universe. The profound philosophical consequence is that expansion is not the movement of galaxies through pre-existing space, but the expansion of the space-time fabric itself. The galaxies are, roughly speaking, dragged along by this expansion, like dots on the surface of a balloon that is inflated. This definitely eliminates the notion of a "center of expansion" or an "explosion site" of the Big Bang. The Big Bang was not an explosion at one point in space; it was an event that occurred everywhere simultaneously, marking the initial high-density condition of the entire space. This understanding destroys the intuitive image of the universe as an object expanding into an external void.
The third, theoretical act was the proposal of cosmic inflation by Alan Guth (1981) and others. Inflation postulates that, in the first moments after the Big Bang (around 10-36 seconds), the universe went through a phase of exponentially accelerated expansion, inflating by a colossal factor (at least 1026). Inflation solves important technical problems of the standard model (such as the horizon and planarity problem), but its ontological consequence is overwhelming: the universe we observe is an infinitesimally small region of a total domain that is immeasurably larger. Inflation suggests that the "total universe" (or "multiverse" in some versions) may be many orders of magnitude larger than the volume contained in our cosmological horizon. If inflation occurred - and the indirect evidence is strong - then the total universe is, by causal principle, inaccessible to our observation. We cannot objectify it because we cannot, and will never be able to, observe it or interact with its entirety. The "thing" we try to name escapes us in a radical and irremediable way.
The fourth, observational act was the discovery of accelerated expansion in the late 1990s. By measuring the brightness of distant supernovae (type Ia), two independent teams (Riess et al., Perlmutter et al.) concluded that the expansion is not slowing down, as would be expected in a matter-dominated universe, but accelerating. This implies the existence of a form of energy with positive density but negative pressure - the so-called dark energy - which constitutes around 68% of the energy content of the universe (Planck, 2018). The philosophical implication is twofold. First, it confirms that the universe does not tend towards a static and balanced final state (an "object" at rest). Second, and more subtle, accelerated expansion makes our cosmological horizon dynamic and contingent. Galaxies that are currently within our causal horizon will end up, in the distant future, crossing it and disappearing forever from our possibility of observation. What counts as "the observable universe" depends on the cosmic moment in which it is observed. There is no fixed and eternal inventory of the observable totality. Once again, the claim to establish the universe as an object with a determined content disappears in time.
In short, contemporary cosmology does not offer a new, more complex model of the object-universe. It describes the systematic failure of any attempt at such modeling. Delimitation is impossible (relative horizons, indeterminate topology). Unification is problematic (hierarchy problem, unknown nature of matter and dark energy). Stable identity is illusory (accelerated expansion, irreversible evolution through radically different eras).
Ontological Distinction: Local Object as Emerging Effect vs. Total Field as a Relational Condition
Given this dissolution, it is crucial to reaffirm that the impossibility of objectifying the universe does not deny the reality or legitimate objectuality of local configurations. A galaxy, a star, a planet, an organism, are real objects. The error is not in attributing objectuality, but in confusing the ontological status of a local emergent effect with the ontological status of the total relational field from which it emerges.
A local object, such as a galaxy, is a pattern of relational stability that acquires a certain autonomy and persistence. Its objectuality is an emerging phenomenon. It arises when a set of relationships (in this case, mainly gravitational) creates a sufficiently strong and coherent bond so that the set behaves as a unit in the face of external interactions, maintaining an approximate shape and identity over a significant period of time. This identity is always provisional and dynamic. The galaxy formed, evolves, merges with others and will eventually dissipate. Its "thing-ness" is an episode within a broader process. Its causal horizon and its cohesion are internal properties of the system, defined in contrast to an external environment.
The total universe, however, is not an emergent effect of broader relationships. He is the field or condition of possibility of all relationships. Therefore, it lacks precisely what defines emergent objectuality: an external environment of contrast. There is no "outside" in relation to which the universe has a form, a cohesion or a horizon. Its "horizon" is a myriad of local horizons. Its "cohesion" on a global scale is negated by accelerated expansion, which promotes dispersal, not collapse. Its "identity" is that of the transformation process itself.
The historian of ideas Alexandre Koyré, in his classic From the Closed World to the Infinite Universe (1957), described the transition of modern cosmology as this title passage. However, the transition is deeper than the mere replacement of a finite content with an infinite content. It is the dissolution of the very category of "world" as cosmos - a word that in Greek means both "universe" and "order, adornment". The ancient and medieval cosmos was a closed, hierarchical, finite and intelligible order, an object of contemplation. THE universum (facing the one) modern and contemporary is an open, acentric, potentially infinite or topologically complex, and intrinsically non-totalizable field. It is no longer a "world"; it is a "universe" in the full sense of its etymology: "turned towards the one", but a one that never concludes as a totality, that remains like a vanishing horizon.
The stubborn attempt to treat the universe as an object generates insoluble intellectual aporias, which are symptoms of the categorical error. If the universe is an object, it must have limits. What lies beyond these limits? If one answers "nothing" or "non-being", how can nothing be a limit to something? If one answers "something else", then the universe is not the totality. This paradox, which has tormented thinkers for centuries, dissolves when the initial assumption is abandoned. The universe has no limits, not because it is infinitely large, but because the category of "limit" does not apply to it. Limits are properties of things within spacetime. The universe is the condition of possibility of space-time and, therefore, of the relationships of interiority and exteriority themselves. Material relationships are not contained in a universe; they constitute the universe.
Conclusion
Contemporary cosmology has not only offered us a broader picture of the universe; showed that the category of object does not apply to the total field of material relations. What emerges locally - galaxies, stars, organisms - are transient effects of functional couplings, while the large-scale real remains a process of reorganisation without an exterior and without substantive unity. The renunciation of objectualization does not lead to a conceptual void, but to an operational opening: thinking of reality as a changing fabric, without an ultimate form that contains it. Matter does not rest in a container - it is the very fabric of reality without an external frame.
"The universe is not an object because the category of object does not apply to the total field of material relations - matter is the very fabric of reality without an external frame."
