Limits of the Knowable: Meaning at the Edges of Cosmology

1 The Universe Between Two Horizons


The Big Bang marks the edge of theory.
The event horizon marks the edge of instance.
And we—everything we know and construe—exist between them.

In this new series, we explore the universe not as a collection of things, but as a dynamic field of meaning bounded by two perspectival horizons: one at the pole of potential, the other at the pole of event. Each marks a limit of construal—not a limit of reality as such, but a limit of what can be construed as reality.


The Big Bang as the Edge of Theory

In classical cosmology, the Big Bang is often imagined as a moment in time—a singular event in the distant past from which the universe "emerged." But in our relational ontology, time is not a container, and the universe is not a sequence of happenings within it. Instead, the Big Bang marks a boundary condition: the outermost edge of what can be theorised as potential.

It is not the first thing that happened.
It is the system pole of cosmic construal.

In the same way that a linguist builds a grammar from observed texts, or a climatologist theorises climate from weather, the cosmologist theorises a structured system—space–time, matter, energy—from the events it makes possible. The Big Bang is the limit condition of that system: the necessary assumption that grounds any possible event, even though no event can directly instantiate it.

It is not before time—it is what makes time construable.


The Event Horizon as the Edge of Instance

At the other end lies the event horizon of a black hole. This is not a mysterious surface where things disappear—it is the outer limit of relational construal. From our position in the universe, nothing that crosses an event horizon can be related to us again. No signal escapes; no difference can be registered. It is not that meaning is destroyed—it is that meaning can no longer be made from here.

The event horizon does not mark the boundary of reality.
It marks the boundary of instance—of what can be construed as an event.

In relational terms, the event horizon is a cut in the field of relation. Beyond it, construal becomes impossible. It is the disappearance of the instance from our field of co-instantiation.


We Live Between the Horizons

Between these two horizons—the edge of theory and the edge of event—lies the field of the knowable. This is not a static region, but a semiotic space: a space of unfolding relation, differentiation, and construal. Every act of knowing takes place here. Every observation, every utterance, every thought.

To say we live “between” the Big Bang and the event horizon is to say:

  • We exist within a system of potential that we can only partially theorise

  • We participate in events whose instances we can only partially construe

  • We are always located within the field of meaning—not beyond it

This is not a position of epistemic defeat. It is a condition of meaningful life.


Two Limits, One Semiotic Field

The Big Bang and the event horizon are not opposite in kind. They are complementary limits—each necessary for the construal of a relational universe.

  • The Big Bang marks the necessary coherence of the system—it holds everything together as potential.

  • The event horizon marks the necessary incompleteness of instantiation—it opens the field to differential relation.

They are the outer faces of a system that is reflexive, recursive, and perspectival.


What This Series Will Explore

In the posts to come, we’ll examine these two horizons more closely—and the space between them. We’ll ask:

  • What does it mean to theorise a universe that can’t instantiate its own boundary?

  • How does the presence of an event horizon change what we mean by “event”?

  • Can the speed of light be understood as the semiotic medium that separates these poles?

  • How do cosmological models reflect our own position within the field they attempt to describe?

Each question points not outward to the cosmos as “object,” but inward to the cosmos as meaning—as a system construed by and within perspective.

We live in a universe bounded not by matter, but by meaning.
And between its horizons, we theorise, we construe, and we become.


2 The Big Bang Is Not a Moment

If the Big Bang is not an event in time,
what exactly is it?

In the mainstream view, the Big Bang is a temporal origin—a “beginning” before which there was nothing. But this view is riddled with paradoxes: What came before time? How can something emerge from nothing? Why is the universe ordered?

In our relational ontology, these paradoxes dissolve—because the Big Bang is not a temporal event at all.
It is a limit condition.
A structured potential.
A semiotic necessity.


The System Pole of the Universe

In systemic linguistics, the system pole is the theorised system from which meanings can be instantiated. It is not prior in time to a sentence—it is its enabling potential. Language unfolds in time, but the system is not in time. It is the structured coherence that makes meaning possible.

The Big Bang serves this role at the cosmological scale.

It is not the first moment in a sequence of events.
It is the ground condition that makes any event at all possible.

It functions as the theory of the universe:

  • It constrains what kinds of spacetime configurations are possible

  • It structures the potentials that later instantiate as matter, energy, relation, and change

  • It is the grammar of the cosmos, not a line in its narrative


Why “Before the Big Bang” Makes No Sense

If the Big Bang is the system pole, then there is no “before” it—not because it happened at time zero, but because time itself is a product of the system.

  • Time is not a container.

  • It is a relational orientation that emerges when potential is instantiated.

  • The system pole does not exist in time; it makes time construable.

So asking what happened “before” the Big Bang is like asking what happens before grammar makes words possible. The question presupposes the very system it tries to precede.


Constraining the Universe as a System

To theorise the universe is to construe it as a system of potential—just as we construe language or music or biology. In this view, the Big Bang functions as the system’s outermost constraint:

  • It sets the symmetry conditions that later break

  • It defines the vacuum from which differentiation emerges

  • It holds open the space for relation to unfold

It is the field in which coherence can be realised, and the cut from which all perspective becomes possible.

The Big Bang is not a fiery explosion.
It is the possibility of difference, waiting to be unfolded.


The Cut from Potential to Instance

We never observe the Big Bang.
What we observe are instances: the distribution of galaxies, the cosmic background radiation, the patterns of matter and energy across space and time.

These are not echoes of a past event.
They are the semiotic traces of a system continually instantiating its own potential.

In this sense, the universe is not a story that begins and ends.
It is an unfolding relation—a construal of meaning between a theorised system and observed instances.

The Big Bang marks one pole of that construal:
The horizon beyond which no further system can be construed.


Why This Matters

By re-reading the Big Bang as the system pole of the universe, we:

  • Reframe cosmology as a mode of meaning-making

  • Dissolve false origin myths in favour of systemic constraint

  • Recognise that our models are not time machines, but grammars of construal

  • Open space for agency, perspective, and variation within a structured field

We do not stand after the Big Bang.
We stand within its unfolding system.

And every construal we make—every observation, every theory—is a differentiation from that potential.


In the next post, we’ll turn to the other side of this field: the instance pole.
If the Big Bang is the limit of what can be theorised,
what is the event horizon?
What is the limit of what can be instantiated?


3 The Event Horizon Is Not a Place

In the popular imagination, the event horizon of a black hole is a kind of “place”—a boundary line in space that, once crossed, cannot be uncrossed.

But in our ontology, this is a profound misreading.

The event horizon is not a place.
It is the limit of construal.
It is the edge of instance.

Just as the Big Bang marks the system pole of the universe—
the outermost potential from which meaning unfolds—
the event horizon marks the inner limit of what can be instantiated.


What Is an Event Horizon?

In physics, the event horizon is the threshold beyond which no signal can reach an outside observer. It’s the boundary of a black hole: anything that crosses it, even light, cannot return.

But here’s the key:
This boundary is defined relationally.

  • It is not a physical surface you can touch

  • It is not the same for all observers

  • It is not part of a single universal now

The event horizon emerges as a cut in the field of possible relation.

It is the limit at which perspective fails to instantiate further meaning.


Instance Without Relatability

In our ontology, meaning arises when a system construes part of itself in relation to another part—when potential is instantiated as perspective.

But the event horizon marks the threshold beyond which no construal is possible.

This means:

  • Not that nothing happens past the event horizon

  • But that nothing can be construed from outside

  • That is: no instance can be co-instantiated with the external field

This is not the absence of activity.
It is the collapse of relation.

The event horizon does not enclose a thing.
It marks the end of what can be meaned.


The Mirror of the Big Bang

In this view, the Big Bang and the event horizon are structural complements:

Big BangEvent Horizon
The outermost system poleThe innermost instance pole
The condition for construalThe boundary of construal
The theorised potentialThe unrelatable event
The limit of meaning’s possibilityThe edge of meaning’s intelligibility

The Big Bang says:
“Nothing can be construed before this.”
The event horizon says:
“Nothing can be construed beyond this.”

Together, they define the field of possible meaning.


Not a Veil, but a Fold

We must not think of the event horizon as a wall behind which reality hides.

It is not a veil.

It is a fold in the fabric of construal—a topological kink in the semiotic space, beyond which perspective cannot reach.

And this too is perspectival.
For different observers, the horizon is not the same.
Just as meaning is not absolute, but co-constructed in relation.

To ask what “really happens” inside a black hole is to ask what happens without instantiation—
a contradiction in terms.

There is no meaning where construal cannot reach.


The Collapse of System into Instance

If the Big Bang is the theorised system
then the black hole is where theory is consumed by its own instantiations.

  • It is not just that meaning ends there

  • It is that system itself cannot remain open

The gravitational collapse is a semantic collapse:
Constraint becomes so extreme that no further variation is possible.
The potential can no longer be held open.

This is the opposite of theorising.
It is the over-realisation of a single point of relation, to the exclusion of all others.


Why This Matters

The event horizon teaches us that
not all reality is available to meaning.
And that meaning itself is bounded—
not by ignorance,
but by structure.

It reminds us that relation is always perspectival.
That every cut between system and instance carries its own horizon.

And that construal is not unlimited.
It happens within a semiotic field
—one that has edges.


In the next post, we draw these threads together.
If the Big Bang is the edge of theory,
and the event horizon is the edge of instance,
then our cosmos lives in between.

4 Living Between Horizons

Between the Big Bang and the event horizon,
we live.

Between the limit of what can be theorised
and the limit of what can be instantiated,
meaning unfolds.

This is not a metaphor.
It is the structure of our universe as construed by consciousness.


A Universe Between Poles

In our ontology, the cosmos is not a container of things,
but a field of relation.

Every event is an instance of potential.
Every perspective is a construal of structure.

But this field is bounded.

  • On one end, the Big Bang marks the outer system pole:
    the grounding condition for relation—the structured potential from which all construal emerges.

  • On the other, the event horizon marks the inner limit of instance:
    the point where relation collapses, and further construal becomes impossible.

These poles are not moments in time.
They are limits of theorising.

They define what meaning can be.


We Are Never Outside

Between these poles, there is no neutral stance.
There is no view from nowhere.
There is only perspective—structured, constrained, unfolding.

Every construal is an act within the system.
We do not map the universe from the outside.
We live inside its unfolding
—as agents of relation
—as participants in meaning
—as instances within the system we theorise.

The system pole makes meaning possible.
The instance pole makes meaning actual.


Time, Light, and Meaning

Light connects these poles.
It is the semiotic tether between what can be related and what can be realised.

  • It bounds what can be seen

  • It conditions what can be known

  • It structures what can be synchronised

We never access the now of elsewhere.
Only the delayed construal of relation—
the shimmer of past light stitched into present perspective.

Time, then, is not a flow from origin to collapse.
It is an orientation within constraint.

It is how meaning holds itself open
between the edge of theory and the edge of event.


Horizon as Condition, Not Limit

We often speak of “pushing the boundaries” of knowledge,
as if meaning were a territory to be expanded.

But the horizon is not a wall.
It is a condition.

The Big Bang is not behind us.
It is beneath us—
the patterned potential that makes relation possible.

The event horizon is not in front of us.
It is within us—
the ever-present limit of what can be co-instantiated,
what can be meant.

Meaning is always made between these poles.

Not despite the constraints—
but because of them.


Living the Cut

To live between the Big Bang and the black hole
is to live within the cut between theory and event.

Every moment:

  • A construal of potential

  • A structuring of relation

  • A local realisation of cosmic grammar

We are not observers of a universe.
We are the universe, theorising itself through perspective.

And in that theorising,
we hold the system open.

We prevent the collapse of all relation into singularity.
We live the field
—and the field lives through us.


What Comes Next?

We began with a question:
What happens at the edge of theorising?

We now see that this edge is not where meaning ends.
It is where meaning begins.

It is where constraint makes creation possible.
Where system and instance meet
in a universe that is both theorised and real.

Our next arc will explore what this means for us:
As persons, cultures, and systems of meaning.

Because if the universe construes itself through us—
then every act of thought is cosmological.
