Introduction — The Problem of an “Edge”
I - The Observational Edge: The Horizon of Visibility
VI - Coherence Without Edge: The Ontological Ground of Value
For centuries we’ve imagined the universe as infinite. Endless. Stretching forever in every direction. But what if that’s wrong? What if the universe actually has an edge? And I don’t mean an edge like the edge of a table floating in empty space. I mean something far stranger - a boundary written into the very geometry of reality itself. In this episode, we explore a stunning new development in cosmology suggesting that the universe may not be infinite after all. Using data from the cosmic microwave background, large-scale structure surveys, and new theoretical models in quantum gravity, scientists are beginning to ask a question that once seemed almost philosophical: Does space itself come to an end? What would it mean if it did? Would there be a wall? A curvature? A fold back into itself? Or something even more bizarre - like space transitioning into a completely different phase of reality? And perhaps most unsettling of all… if there is an edge, what lies beyond it? This is not science fiction. This is physics at the frontier - where geometry, quantum theory, and cosmology collide. And the answer may permanently change how you think about infinity.
Because today's topic seems complex - and it is - I have provided helpful video presentations through many of the sections along with graphic illustrations. However, by doing so, I have created "interrupters" to my overall essay on reality's ontology... thus my caution here. I am not so much teaching cosmology as teaching the processual form of ontology that LIES BEHIND the physics of the universe - which is the actual point of this essay: To practically demonstrate how reality's ontology is expressed through the science of cosmology's theorized origination structures. So that when looking at the universe's constructs we might be able to encounter and discuss how reality might work from a processual perspective.
Moreover, as a process theologian, we will at a later date discuss the metaphysics of reality and then its theology. Which means there will be more essays to come on the subject of "What Is Reality?" and "What Does this Form of Reality Mean for Me?" For now, let us look at the physics of the universe and contemplate what it might mean for the kind of reality we seem to be living within.
In summary, when we ask "What is reality's construction?" We are asking of its ontology. And when we ask "Why might this matter?" We are asking how "Identity, Value, and Meaning" might arise from within reality's structure - which has been the subject of essays 27-31 which we have been pursuing as our final capstone project. And lastly, as a further help in facilitating this seminal project, we have been developing the ontological concept of "Embodied" Processual Realism - an ontological concept which I'll be referring to at the end of each of today's theoretical sections, then summarize in the final Coda section. This, then, is the intended scope of today's essay.

Preface
The question of whether the universe has an edge has long occupied both scientific imagination and philosophical reflection. For centuries, the dominant intuition has been that reality must either extend infinitely or terminate at some ultimate boundary. In either case, the structure of the universe was assumed to be defined by limits - whether external or conceptual - within which existence unfolds.
Recent developments in cosmology have unsettled this assumption.
The possibility that the universe may be finite yet without boundary, self-contained yet without external frame, challenges not only our spatial intuitions but our deepest metaphysical habits. In such a universe, the notion of an “edge” no longer functions as a defining feature of reality. Instead, what appear as limits become transitions - shifts in structure, coherence, or accessibility rather than terminations of being.
This shift is not merely scientific. It is ontological.
If reality is not bounded in the manner we have traditionally assumed, then ontological identity itself cannot be grounded in fixed limits or discrete containment. What persists is not defined by where it ends, but by how it holds together. Identity, in this sense, becomes an achievement of coherence - an ongoing stabilization within relational becoming.
This essay extends the present trajectory established in Identity Across Becoming in a Relational Universe (essay 29) by examining what identity means in a universe without edge. It draws upon contemporary cosmological models - observational, geometric, and theoretical - not as final descriptions of reality, but as indicators of a deeper shift:
the movement from boundary-based thinking to condition-based understanding.
Within an Embodied Process Realism framework, the absence of boundary does not imply indeterminacy or formlessness. Rather, it suggests that structure arises internally, through the integration of relations that stabilize into recognizable patterns. What appears as a “thing” is not bounded from without, but cohered from within.
From this perspective, the question of identity naturally gives rise to a further question: if coherence can be achieved without edge, how does it come to matter? What distinguishes one configuration of coherence from another in terms of significance, intensity, or worth?
This is the question of value.
Thus, the movement of this essay is twofold:
First, it clarifies the multiple meanings of “edge” within contemporary cosmology, dissolving the assumption that reality must be defined by external limits.
Second, it reinterprets these findings through a process-relational lens, showing how coherence without boundary provides the ontological ground from which value can emerge.
In a universe without edge, reality is not less structured. It is more deeply structured than we had imagined.
Its limits are not where it ends, but how it becomes.
Introduction - The Problem of an “Edge”
The question of whether the universe has an edge has re-emerged in contemporary cosmology with renewed intensity. Advances in observational precision, combined with increasingly sophisticated theoretical models, have reopened what once appeared to be a settled assumption:
that the universe either extends infinitely
or is bounded in some ultimate sense.
Yet the reappearance of this question has not produced clarity so much as complexity.
The term edge - seemingly simple - has come to carry multiple, overlapping meanings. In current discussions, it may refer to:
- the limits of observation,
- the global structure of space,
- the behavior of cosmological fields,
- the conditions of the universe’s origin,
- or even the breakdown of spacetime itself.
These are not variations of a single idea, but distinct conceptual frameworks, each operating at a different level of explanation. In the sections that follow, we will examine each of these meanings as they relate to the question of the universe’s “edge.”
When these meanings are conflated, the result is a misleading picture: the suggestion that there exists a single, discoverable boundary at which the universe ends. In reality, what is being described across these models is not a singular edge, but a series of limits - each marking a transition in how reality is structured, accessed, or understood.
To ask whether the universe has an edge, therefore, is not to pose a single question, but many, which we will also review through each of the sections below:
- Is the edge a limit of what can be observed?
- Is it a feature of spatial structure?
- Is it a boundary between distinct physical regimes?
- Is it the absence of an initial condition?
- Or is it the point at which spacetime itself ceases to apply?
Each of these questions is legitimate. Each has been explored within contemporary physics. Yet each belongs to a different order of explanation, and none can be substituted for the others without loss of precision.
The task of this essay is to disentangle these meanings and to clarify the distinct senses in which an “edge” may be said to arise in modern cosmology. Only through such clarification can the deeper implications be brought into view.
For if the universe does not possess an edge in the way we have traditionally imagined, then the consequences extend beyond cosmology. They reach into the nature of identity itself.
A reality without edge cannot be understood in terms of fixed boundaries or external limits. What persists within such a reality must do so not by delimitation, but by coherence. Identity, in this context, is no longer defined by where something ends, but by how it holds together across change - in other words, how identity coheres across relational becoming.
The clarification of cosmological “edges,” therefore, is not an abstract exercise. It prepares the ground for a more fundamental insight: that what we have taken to be boundaries of existence may in fact be conditions of its becoming.
What we have taken to be the boundary between something and nothing is better understood as a transition between degrees of relational coherence:
There is no boundary between something and nothing - only transitions in the coherence through which reality becomes.
The clarification of cosmological “edges,” therefore, is not an abstract exercise. It prepares the ground for a more fundamental insight: that what we have taken to be boundaries of existence may in fact be conditions of its becoming.
What appears as the boundary between something and nothing is not a division in being, but a transition in the degree to which relations achieve coherence.
I. The Observational Edge: The Horizon of Visibility
The observational horizon does not mark the edge of reality, but the limit of what can presently be known.
The most immediate and empirically grounded sense in which the universe may be said to have an “edge” arises from the limits of observation.
Because light travels at a finite speed and the universe has a finite age, there exists a maximum distance from which information can reach us. This limit defines what is known as the observable universe - a spherical region centered on the observer, extending outward to approximately 93 billion light-years in diameter.
This boundary is not an edge of space itself. It is an edge of visibility.
The distinction is crucial. The observable universe is not a container within which reality exists, but a horizon defined by the conditions under which light - and therefore information - can be received. Beyond this horizon, there may exist additional regions of space, galaxies, and structure. Their absence from observation reflects not their non-existence, but the temporal limits of causal contact.
This horizon evolves. As time passes, light from more distant regions continues to arrive, expanding the domain of what can be observed. At the same time, the accelerating expansion of the universe ensures that some regions recede beyond the possibility of future observation. The boundary is therefore dynamic - shifting not as a fixed edge, but as a function of cosmological development.
What appears as a limit is therefore relational.
It depends upon the position of the observer, the age of the universe, and the structure of spacetime through which light propagates. There is no privileged center from which the edge is measured; every observer occupies a position from which a horizon is defined.
In this sense, the observational “edge” is not a feature of reality in itself, but a feature of the relationship between observer and cosmos.
This has important implications. It means that the most immediate sense in which the universe appears bounded is not ontological but epistemic. The boundary does not mark where reality ends, but where knowledge - marked by present conditions - reaches its limit.
And yet, even in this limited sense, something significant is revealed.
For the existence of a horizon demonstrates that access to reality is always mediated. What can be known is conditioned by the structure of spacetime and the processes through which information travels. The universe is not known in its totality, but encountered through a field of partial disclosure.
Within an Embodied Process Realism (EPR) framework, this boundary may be understood not as a termination, but as a limit of integration. It marks the extent to which relational coherence can presently be incorporated into experience and understanding.
The observational edge, then, is not where reality ceases.
It is where coherence, for us, has not yet arrived.
EPR Interpretation
What appears as an edge at the level of observation will, at deeper levels of analysis, reveal itself not as a boundary of space, but as a feature of its structure.
II - The Topological Edge: Finite Without Boundary
Topology shows that space may be finite without boundary, dissolving the assumption that shape determines an edge.
To approach this question, a crucial distinction must be made - one that is often overlooked in popular discussions of cosmology: the distinction between geometry and topology.
Geometry concerns the local properties of space - its curvature, the behavior of parallel lines, the angles of triangles. It tells us how space is shaped in the immediate sense.
Topology, by contrast, concerns the global structure of space - how it is connected, whether it loops back on itself, whether it is finite or infinite as a whole.
This distinction matters because the geometry of the universe has been measured with remarkable precision through observations of the Cosmic Microwave Background (CMB). These measurements indicate that space is, to a very high degree of accuracy, spatially flat.
Yet flatness does not imply infinitude.
A space may be geometrically flat while still being topologically finite. A simple analogy can be drawn from a two-dimensional surface. A flat sheet of paper is both flat and bounded. But if that sheet is conceptually “wrapped” so that opposite edges connect - forming a cylinder, or more completely, a torus, which also "wraps" the ends to one another - it becomes finite without possessing an edge that can be encountered from within.
In such a space, a traveler moving in a straight line would not encounter a boundary. Instead, given sufficient distance, they would return to their starting point. The space contains no edge in the experiential sense, even though it is not infinite.
Cosmological models allow for similar possibilities in three dimensions. A universe may be "multiply-connected" in its structure such that paths through space eventually close upon themselves. In these models, what appears locally as an unbounded expanse is globally self-contained.
The implication is subtle but profound.
The absence of an edge does not require the presence of infinity. It may instead reflect a deeper form of closure - a condition in which space is complete in itself, requiring no external extension.
This challenges a deeply ingrained intuition: that finitude must imply boundary. In topological terms, this is not the case. A space may be finite in extent and yet without edge, because its structure does not terminate but reconnects.
Current observational efforts have sought signatures of such topologies - for example, repeating patterns or “matched circles” in the cosmic microwave background that would indicate light traversing a closed spatial structure. While no definitive evidence has yet confirmed a specific topology, neither has the possibility been ruled out. The scale at which such closure might occur could exceed the observable universe, placing it beyond present detection.
Thus, at the level of topology, the notion of an edge undergoes a transformation.
It is no longer a boundary at which space ends, but a question of whether space, as a whole, requires an edge at all - regardless of how its shape and curvature are locally expressed.
II
To further clarify this distinction, it is helpful to note that cosmological models are often classified in terms of their large-scale geometry - whether space is flat, positively curved, or negatively curved. Yet theoretical physics allows for combinations in which geometry and topology do not straightforwardly determine one another.
1 - A geometrically flat universe, for example, is commonly understood as extending infinitely in all directions. This is the standard interpretation supported by current observational data, including measurements of the cosmic microwave background.
However, flatness alone does not entail infinitude. A flat universe may also be multiply connected - topologically finite - such that a trajectory through space eventually returns to its point of origin, as in the case of a three-dimensional torus. In such a model, space is unbounded in experience yet finite in extent.
2 - Similarly, a positively curved universe - analogous to the surface of a sphere - is finite and without boundary. In certain quantum cosmological models, including the no-boundary proposal developed by James Hartle and Stephen Hawking, this curvature is associated not only with spatial structure but with the earliest conditions (time-wise) of the universe itself. In these formulations, the distinction between space and time becomes fluid, and the universe is described as finite yet without an initial edge.
3 - Negatively curved models, by contrast, describe a universe in which spatial trajectories diverge, often implying an infinite extent. Yet even here, the absence of boundary remains. Whether finite or infinite, flat or curved, the presence or absence of an edge is not determined by curvature alone.
What these variations demonstrate is that geometry describes how space is locally shaped, while topology determines how it is globally organized. The question of an edge belongs to the latter. To global topology.
EPR Interpretation
Inflation reframes edges as transitions between cosmological regimes rather than boundaries in space.
A third sense in which the universe may be said to have an “edge” arises not from observation or spatial structure, but from the dynamics of its early cosmological development.
This meaning emerges within the framework of cosmic inflation - a theoretical model proposed to explain several otherwise puzzling features of the universe, including its large-scale uniformity, flatness, and the absence of detectable curvature at observable scales.
According to inflationary cosmology, the universe underwent a period of extraordinarily rapid expansion in its earliest moments. During this phase, space itself expanded exponentially, smoothing out irregularities and establishing the large-scale conditions observed today.
1 - In its standard form, inflation is a local event that transitions into the slower expansion described by conventional cosmology. However, in many extended models - particularly those associated with eternal inflation - this transition does not occur uniformly across all regions.
Instead, inflation may continue indefinitely in some regions while ending in others.
The result is a cosmological picture in which our observable universe is one region - often described as a “bubble” - within a vastly larger and dynamically evolving background. In this context, the “edge” of our universe is not a spatial boundary that can be reached or crossed, but a transition in the state of a field: the point at which inflation ended locally and standard physical processes began.
This boundary is not located in space in the conventional sense. It is not a surface separating two regions within a shared geometry. Rather, it is a distinction between different regimes of physical evolution - a shift in how space itself behaves.
2 - Other such "bubble-regions/spaces" may exist, each emerging-and-propagating from similar transitions. These “bubble universes” may differ in their physical parameters-and-laws, depending on the conditions under which inflation ended. In this way, the concept of a multiverse arises - not as a speculative addition, but as a natural consequence of certain inflationary models.
The important point, however, is not the multiplicity of universes, but the transformation of what is meant by an edge.
In this framework, an edge is not where space stops.
It is where a process changes.
The boundary is dynamic rather than geometric. It marks not the termination of extension, but the differentiation of behavior - one region of spacetime evolving under one set of conditions, another under a different set.
This reframing carries significant implications.
It suggests that what appears as a boundary may be better understood as a threshold - a point of transition between modes of becoming. The universe, in this sense, is not divided by edges, but articulated through phases.
And these phases are not static partitions, but unfolding processes.
Within an Embodied Process Realism framework, the inflationary “edge” is best understood not as a boundary of space, but as a transition between regimes of relational coherence.
What distinguishes one region from another is not its position relative to an external limit, but the manner in which its internal relations have stabilized into a particular pattern of evolution.
The boundary, therefore, is not spatial but processual.
It marks a shift in how coherence is organized - how potential becomes actual, how structure emerges from fluctuation, how one mode of becoming gives way to another mode of becoming.
In this light, the universe is not partitioned by edges, but differentiated by transitions.
Reality does not end at such thresholds.
It transforms.
The no-boundary proposal removes the beginning of time, replacing it with a smooth transition in the structure of spacetime.
Classically, cosmology has been framed in terms of an initial moment - a beginning of time from which the universe emerges and unfolds. Within this framework, the question naturally arises: what preceded this beginning, and what conditions gave rise to it?
Yet within the framework of general relativity, this question encounters a limit. When the equations describing spacetime are extended backwards toward the earliest moments of the universe, they converge toward a singularity - a point at which density, temperature, and curvature become infinite, and the theory itself ceases to provide meaningful description of spacetime as a coherent structure.
This breakdown has often been interpreted as indicating the existence of an initial boundary - a temporal edge at which the universe begins.
However, developments in quantum cosmology suggest a different possibility.
II.
In the no-boundary proposal, developed by Stephen Hawking and James Hartle, the universe is described not as emerging from a singular beginning imposed from outside, but as a self-contained system whose geometry does not require an initial boundary condition.
In this model, the distinction between time and space, which is fundamental to our everyday understanding, becomes blurred at the earliest stages of the universe. Near what is conventionally called the “beginning,” time behaves more like a spatial dimension. That is, rather than there being a “before” the Big Bang in any ordinary temporal sense, the structure of spacetime transitions into a regime in which time is no longer distinct from space. Thus, the universe might have been finite in extent, yet without a temporal edge in the classical sense.
A familiar analogy is that of the surface of a sphere. The surface is finite, yet it contains no boundary or edge. There is no point that can be identified as the beginning or end of the surface. Every point is locally similar, and the structure is complete in itself.
In a similar way, the no-boundary model suggests that the universe is finite but without a beginning in time that requires external explanation. The question of what came “before” loses its meaning, not because the answer is unknown, but because the framework required to pose the question does not apply.
To ask what precedes the beginning of time is analogous to asking what lies north of the North Pole.
The limitation is not in knowledge, but in the applicability of the concept.
This represents a profound shift in the understanding of cosmological origin.
The universe is no longer viewed as something that begins at a boundary, but as something that is self-contained in its existence. Its origin is not an external event, but an intrinsic feature of its structure.
In this sense, the “edge” at the beginning of time dissolves.
What remains is not a boundary, but a condition - one in which the
universe exists without requiring an external starting point.
EPR Interpretation
Within an Embodied Process Realism framework, the no-boundary condition reinforces the view that reality is not initiated from an external limit, but arises as a self-consistent field of relational coherence.
The absence of an initial edge does not imply the absence of structure. Rather, it suggests that structure emerges internally, without dependence upon an externally imposed beginning.
Temporality itself becomes an achievement - a directional unfolding that arises within the ongoing stabilization of relations.
What we call “the beginning” is not a boundary of existence, but a transition in the mode of coherence through which reality becomes temporally articulated.
In this light, reality is not something that starts.
It is something that becomes as coherence is achieved.
The No Boundary Universe, Quantum Cosmology, Imaginary Time, Euclidean Path Integral, and Quantum Gravity reshape our understanding of the cosmos. Instead of a singular Big Bang, spacetime smoothly unfolds from a compact geometry. The No Boundary Universe, Quantum Cosmology, Imaginary Time, Euclidean Path Integral, Quantum Gravity — what if the universe didn’t begin with an abrupt bang but smoothly unfolded from a timeless, boundaryless state? The No Boundary Universe explores Hawking and Hartle’s radical vision where time acts like space at the origin, rounding off the cosmos without singularities. The Big Bang becomes not a birth, but a geometric transition—shaping everything we observe today.
In this film Stephen Hawking, James Hartle and Thomas Hertog explain their model of the early universe: The No Boundary Proposal. In the 1960’s and 70’s Hawking and Penrose showed that according to classical general relativity, given some minimal assumptions the origin of an expanding universe is a singularity: a point of infinite density and spacetime curvature. But this and other singularity theorems do not take into account the strange world of quantum mechanics. So in the 1980’s Hawking and collaborators started to build a model of the big bang that included quantum effects.The result is the No Boundary Proposal, a model that may be able to explain some of the deepest mysteries of the cosmos such as, is there a multiverse? how is there an arrow of time and what really happened a the big bang?
The no-boundary proposal removes the beginning of time so that emergent spacetime theories remove the assumption that time and space are fundamental at all.
A fifth and more radical sense in which the universe may be said to have an “edge” arises at the frontier where spacetime itself is no longer taken as fundamental.
In classical physics, space and time provide the stage upon which all events occur. Even in the relativistic framework of Einsteinian gravity, spacetime remains a continuous geometric structure - dynamic, curved, and responsive, yet still the foundational medium within which physical processes unfold.
However, attempts to reconcile gravity with quantum theory (refer to essay 14 - Gravity, Coherence, and the Real) have increasingly pointed toward a different possibility: that spacetime is not fundamental, but emergent.
In several leading approaches to quantum gravity - including loop-based models, holographic dualities, and quantum informational frameworks - space is understood as arising from deeper, non-geometric structures. These may take the form of discrete relational networks, algebraic structures, or patterns of quantum entanglement from which spatial extension and geometry are derived.
Within such frameworks, the smooth continuity of spacetime is not a primitive feature of reality, but a large-scale approximation - analogous to the way fluid continuity emerges from the collective behavior of discrete molecules.
This shift carries profound implications for the concept of an edge.
If spacetime itself is emergent, then it may not exist under all conditions. There may be regimes in which the relational structures that give rise to geometry no longer stabilize into a coherent spacetime. At such limits, the familiar notions of distance, direction, and location cease to apply.
In this context, an “edge” is no longer a boundary within space.
It is a boundary of space.
It marks the transition between a regime in which relational coherence gives rise to geometric structure and one in which that coherence no longer supports the emergence of spacetime as such.
Such a boundary cannot be approached as a location. It cannot be crossed in the manner of moving from one region of space to another, because the very framework that would define such movement is no longer available.
The edge is not somewhere.It is a condition.
This condition may be encountered conceptually in several domains: 1) at the Planck scale, where quantum fluctuations of geometry become dominant; 2) in the vicinity of singularities, where classical spacetime descriptions break down; or, 3) in the earliest moments of cosmological evolution, where the distinction between space and time becomes indeterminate.
In each case, what is encountered is not a wall or boundary, but the limit of applicability of spacetime itself.
This reframing represents a decisive transformation in the understanding of cosmological limits.
The universe is no longer bounded by edges within space, nor even defined by the absence of such edges. Rather, it is understood as a structure that emerges under certain conditions - and that may, under other conditions, dissolve into a more fundamental, pre-geometric domain.
Within an Embodied Process Realism framework, the emergent “edge” represents the deepest expression of a limit in relational coherence.
Here, the question is no longer how far space extends, or whether it loops back upon itself, or how it began. The question is whether the relational structures that sustain spacetime remain sufficiently integrated to stabilize into geometry at all.
The edge, in this sense, marks the limit at which coherence can no longer maintain a particular mode of manifestation.
Beyond this limit lies not nothing, but a domain in which relational potential has not stabilized into the structures recognizable as space and time. It is a field of possibility, not yet organized into the forms through which experience ordinarily proceeds.
Thus, the deepest boundary is not spatial, temporal, or even dynamical.
It is structural.
It marks the transition between coherence that manifests as a world and coherence that remains unexpressed as such.
In this light, what we call reality is not defined by its edges, but by the processual conditions under which coherence achieves form.
This is a collection of some animations I made for a documentary series, where Stephen Hawking, James Hartle and Thomas Hertog present their model, the "No Boundary Proposal". It takes quantum effects into account and may be able to explain if there is a multiverse, why there is an arrow of time and what really happened at the big bang.
What exists beyond the observable universe? This is no longer just a philosophical question - it is a physics one. Scientists have published four peer-reviewed models that attempt to answer what lies beyond the cosmic horizon.
- Cosmologist Jean-Pierre Luminet proposed a finite universe with no edge.
- MIT physicist Alan Guth's eternal inflation theory suggests an endless multiverse of bubble universes.
- Max Tegmark's infinite universe model mathematically guarantees infinite copies of you exist right now.
- Nick Bostrom's simulation argument from Oxford changes the question entirely.
Each model is evidence-based. Each one is deeply unsettling.
A conceptual rendering of reality as a field of relational integration in which structure emerges without external boundary. Coherence intensifies toward regions of greater integration, while dissolving into pre-geometric potential at its limits. What appears as boundary is revealed as transition; what persists does so through coherence rather than containment. | Illustration by R.E. Slater & ChatGPT
Value emerges not from external boundaries, but from the degree to which relational coherence is achieved and sustained.
What began as the search for a limit at which reality ends has given way to a series of insights in which apparent edges resolve into conditions, transitions, or limits of applicability.
Taken together, these developments suggest a fundamental reorientation.
Reality is not best understood as something bounded.
It is better understood as something cohering.
This shift carries immediate implications for the concept of identity. If the universe does not possess edges in the traditional sense - if its limits are not defined by termination but by transitions in structure and coherence - then identity itself cannot be grounded in fixed boundaries or external containment.
Identity must instead be understood as an achievement.
It arises where relations stabilize.
It persists where coherence is maintained.
It changes where coherence is reconfigured.
Within such a framework, what we call a “thing” is not a self-contained object with intrinsic boundaries, but a pattern of relations that has achieved sufficient integration to sustain itself across conditions. Its apparent unity reflects not an imposed limit, but an internally maintained organization.
This redefinition of identity opens directly into the question of value.
For if identity is constituted by degrees of coherence, then not all configurations of coherence are equivalent. Some patterns integrate more extensively, sustain themselves more robustly, or generate more complex forms of relational interaction than others.
II - Value
Value, in this sense, is not an external property assigned to things.
It is a feature of how coherence is achieved.
A configuration of relations that stabilizes into a durable, integrated pattern carries a different ontological weight than one that dissipates rapidly or fails to organize. Similarly, structures that enable further coherence - supporting the emergence of additional patterns, interactions, or forms of integration - possess a generative significance that exceeds those that do not.
Value thus emerges as a measure - not in the quantitative sense, but in the ontological sense - of the intensity, stability, and generativity of coherence.
This perspective reframes several long-standing philosophical distinctions.
The difference between existence and significance, between being and value, begins to dissolve. To "be" is not merely to exist, but to achieve a certain degree of coherence. To "matter" is to participate in patterns of integration that sustain and extend relational structures.
Moreover, it is not without reason then that "to be" and "to matter" are longstanding observations that have resonated with philosophical and theological reflections on the meaning and purpose of life.
Accordingly, in a universe without an edge, there is no external standpoint from which value can be imposed. There is no boundary beyond which meaning is defined or secured. Instead, value arises internally, through the ways in which coherence organizes, persists, and transforms.
This does not imply that all forms of coherence are equal.
On the contrary, it allows for differentiation at a deeper level.
Some forms of coherence are minimal, maintaining only transient or localized integration. Others are more complex, coordinating multiple processes across extended scales. Still others exhibit the capacity to reflect upon their own coherence, giving rise to awareness, interpretation, and the deliberate cultivation of value itself.
In such cases, value becomes not only an emergent feature of coherence, but an active dimension of its further development.
The emergence of life, consciousness, and reflective agency may thus be understood as progressive intensifications of coherence - each stage introducing new possibilities for the organization and evaluation of relational structures.
Within this progression, value is not an accidental byproduct.
It is a natural expression of coherence reaching higher orders of integration.
From the perspective of Embodied Process Realism, this implies that value is neither reducible to subjective preference nor dependent upon external grounding. But arises wherever coherence achieves forms capable of sustaining and extending relational integration.
III - Meaning
Meaning, in turn, may be understood as the interpretive dimension of this process - the way in which coherence becomes intelligible to itself within systems capable of reflection.
Thus, identity, value, and meaning form a continuous sequence.
- Identity emerges as stabilized coherence
- Value arises as the qualitative differentiation of such coherence
- Meaning develops as the interpretive articulation of value within reflective systems
This sequence does not depend upon the existence of edges.
It depends upon the capacity of reality to organize itself into coherent patterns.
In a universe without boundary, the question is not where things end.
It is how they hold together - and what follows from that holding.
This is what AN Whitehead meant when saying -
"The many become one, and are increased by one."
And in conjunction with Whitehead what EPR means when stating-
"Reality does not end at boundaries; it coheres through them."
VII - Coda: The Universe Without Outside
A universe without edge is a universe without outside, in which reality differentiates through coherence rather than termination.
If the preceding analysis has shown anything, it is that the concept of an “edge” dissolves not into absence, but into transformation.
At every level of inquiry - observational, structural, dynamical, temporal, and ontological - the search for a boundary at which reality ends gives way to a recognition that what appears as a limit is more properly understood as a condition. The universe does not terminate at edges; it differentiates through them.
What follows from this is not merely a revision of cosmological models, but a reorientation of how reality itself is to be conceived.
A universe without edge is a universe without outside.
This does not mean that nothing lies beyond what is known, nor that reality is exhausted by what can be observed. Rather, it means that the framework within which “beyond” would be meaningfully described does not apply at the level of the whole.
- There is no external space into which the universe extends.
- No temporal background against which it begins.
- No enclosing structure within which it is contained.
The universe is not in something.
It is.
This is not a statement of completeness in the sense of finality, but of self-containment in the sense of coherence. The absence of an outside does not render reality closed in a static sense. On the contrary, it underscores the fact that all differentiation, development, and transformation occur internally, through the ongoing reconfiguration of relations.
In such a universe, the classical image of a boundary separating what is from what is not gives way to a different understanding.
There is no line at which being gives way to non-being.There are only transitions between forms of coherence.
What we encounter as limits - whether of observation, structure, or conceptual applicability - does not mark the end of reality. They mark the limits of particular modes through which reality becoming accessible, structured, or intelligible.
This has implications that extend beyond cosmology.
- If reality has no outside, then identity cannot be grounded in external delimitation. What something is cannot be defined by what lies beyond it, because there is no “beyond” in that sense. Identity must instead be grounded in the manner in which coherence is achieved and sustained within the field of relations that constitute it.
- Similarly, value cannot be imposed from an external standpoint. There is no vantage point outside the universe from which significance is assigned. Value must arise internally, through the ways in which coherence differentiates itself - through the intensities, stabilities, and generative capacities of relational configurations.
- Meaning, in turn, is not anchored in a transcendent frame that lies beyond the world, but emerges within the processes through which coherence becomes capable of reflecting upon itself.
Thus, the absence of an outside does not diminish the significance of reality.
It deepens it.
For it reveals that everything that can matter does so from within the same field of becoming. There is no external ground to which meaning must appeal. There is only the ongoing articulation of coherence as it organizes, persists, and transforms.
In this light, the question with which we began - whether the universe has an edge - returns in a different form.
Not as a question about where reality ends.
But as a question about how reality becomes.
And the answer, as it has unfolded across these reflections, is that reality does not terminate at boundaries.
It differentiates through coherence.

A.1 - The Standard Cosmological Model (ΛCDM)
The Lambda-CDM_model is the prevailing model of modern cosmology describing a universe that is expanding, spatially flat, and composed primarily of dark energy (Λ) and cold dark matter (CDM). It provides the best current fit to observational data, including the cosmic microwave background and large-scale structure.
Within this model, no physical edge of space is required. The universe may be infinite, or it may be finite with a topology beyond current observational reach.
A.2 - Cosmic Inflation
The Cosmic Inflation Model proposes a period of rapid exponential expansion in the early universe, resolving the horizon and flatness problems. It explains why distant regions appear uniform despite limited causal contact.
A.3 - Eternal Inflation and the Multiverse
A.4 - The No-Boundary Proposal
The Hartle–Hawking model removes the need for an initial temporal boundary. The universe is finite but without a beginning in time as conventionally understood.
EPR Note:
Supports the idea of reality as self-contained coherence without externally imposed origin.
A.5 - Loop Quantum Gravity
The Loop Quantum Gravity approach suggests spacetime is discrete at the smallest scales. It eliminates classical singularities and replaces them with quantum structures.
EPR Note:
Coherence is granular and relational at its base - not continuous substance but structured interaction.
A.6 - Holographic Principle
The Holographic Principle suggests that spacetime geometry emerges from lower-dimensional quantum systems. Space is not fundamental but derived.
EPR Note:
Strongly aligns with EPR: structure emerges from relational information rather than pre-existing spatial substrate.
A.7 - Emergent Spacetime Theories
Various approaches suggest spacetime arises from quantum entanglement or informational structures.
EPR Note:
Reinforces the idea that coherence precedes geometry.
A.8 - Cyclic and Bouncing Universes
The Cyclic Universe and Bouncing Universe models propose repeated expansions and contractions, avoiding a singular beginning.
EPR Note:
Emphasizes continuity of process rather than discrete origin events.
A.9 - Dark Energy and Cosmological Futures
The accelerated expansion of the universe by dark energy may lead to heat death or, in some models, a “Big Rip.”
EPR Note:
These represent limits of coherence persistence rather than external termination.
Embodied Process Reality says that reality is not made of bounded things, but of relational coherences that stabilize, differentiate, and intensify. Each “edge” in cosmology corresponds not to a boundary of reality, but to a transition in the depth and organization of relational coherence. Or, more simply, The universe does not end, it coheres. - RE Slater
