Time through the Reactive Substrate Theory (RST) Lens

📺 Video Review: The "All At Once" Universe

The video, "The 'All At Once' Universe Shatters Our View of Time", argues that time, as we experience it, is an emergent, macroscopic phenomenon and not a fundamental aspect of the universe's ultimate physical laws.

The Key Points:

  • The "All At Once" View: Dr. Adlam suggests that the fundamental laws of physics are not equations evolving an initial state forward in time, but global constraints that select valid patterns across the entirety of spacetime simultaneously. This is illustrated with the Sudoku Universe analogy.
  • Analogy: Just as Sudoku rules constrain the entire grid, the laws of physics constrain the entire history of the cosmos. The final outcome is not a product of evolution but of global consistency.
  • The Problem of Time: Attempts to unify Quantum Mechanics (QM) and General Relativity (GR) via canonical quantization result in a timeless model where time evolution mathematically vanishes, suggesting time is fundamentally absent.
  • Causation as Macroscopic: Causation and the arrow of time are tied to entropy and macroscopic observers, not embedded in microscopic laws.
  • Temporal Non-locality: The "all at once" approach favors global, atemporal relationships over step-by-step causal influence, with the entire history fixed by consistency constraints.

⏳ Time through the RST Lens

In Reactive Substrate Theory (RST), time is defined as the measurement of dynamic change within the fundamental, continuous, non-local field known as the Substrate (Σ). Time is not fundamental but emergent.

  • The Substrate is Timeless: The Σ field itself is atemporal. It simply exists as a continuous, high-tension medium providing the potential for all interactions.
  • Time as Emergent Change: The arrow of time arises from irreversible, entropic stress dissipation within Σ.
  • Matter as Stress: All matter and energy are local knots of tension (Σ solitons) within the continuous field.
  • The Arrow: The universe tends toward minimal potential stress (Σmin). Dissipation of tension knots defines the unidirectional flow we call time.
  • Duration as Interaction Rate: An interval of time is the count of fundamental Σ interactions required for macroscopic change.

In RST, time is the shadow cast by the entropic dynamics of the Σ field.


↔️ Comparison: "All At Once" vs. RST

Feature Video's "All At Once" View Reactive Substrate Theory (RST) View
Fundamental Status Atemporal. Time is absent from fundamental laws; the universe is a static global pattern (Eternalism). Emergent. Time arises from dynamic change and entropic dissipation of Σ, which is itself timeless.
Origin of Time's Arrow Macroscopic/Epistemic. The arrow is rooted in entropy and coarse-graining by observers. Ontological. The arrow is the physical consequence of Σ’s irreversible drive to dissipate stress toward Σmin.
Spacetime Global mathematical structure constrained by laws. Emergent geometry of Σ, with time as the measure of Σ’s change.
Mechanism of Link Global Constraint: outcomes fixed by non-causal consistency across history. Local Dynamics: outcomes emerge from continuous Σ interactions driving toward lower tension.

📌 Agreement and Difference

Both views reject the traditional notion of time as a fundamental river flowing forward. Both tie the arrow of time to entropy and macroscopic perspective. The key difference is that the "All At Once" view replaces time with a static global consistency constraint (a theory of pattern), while RST replaces it with universal, irreversible dynamic change in a timeless medium Σ (a theory of process).

⚛️ The RST Main Equation and the Nature of Time

Reactive Substrate Theory (RST) expresses the dynamics of the universe through its central field equation:

(∂t²S − c²∇²S + βS³) = σ(x,t) ⋅ F_R(C[Ψ])

🔹 Left-Hand Side: Internal Dynamics of Σ

This side describes the intrinsic behavior of the Substrate field (Σ):

  • ∂t²S: The second time derivative of the substrate tension S, showing how the field oscillates or accelerates.
  • c²∇²S: The spatial Laplacian scaled by the speed of light squared, representing how tension propagates across space.
  • βS³: A nonlinear self-interaction term, preventing infinite compression and stabilizing the field.

Together, these terms define the continuous, wave-like, and self-limiting dynamics of Σ. Importantly, they show that time is not a flowing dimension but a parameter of change — an infinitely divisible instant measured by substrate interactions.


🔹 Right-Hand Side: External Coupling

This side represents how external sources and quantum information interact with Σ:

  • σ(x,t): Local stress or source term, dependent on position and time.
  • C[Ψ]: The coherence functional of quantum states Ψ, encoding correlations and entanglement.
  • F_R(C[Ψ]): The response of the substrate to quantum coherence, translating information into macroscopic effects.

This coupling ensures that matter, energy, and information are never lost but redistributed through the substrate.


🚫 Why Time Travel Is Ruled Out

The left-hand side of the equation makes clear that time is not a separate dimension in which one can move backward or forward. Instead:

  • Time is the measure of Σ’s continuous change — not a container of events.
  • Past and future do not exist as independent realms; all of reality is the eternal present.
  • Because time is infinitely divisible, each “moment” is simply the resolution of substrate interactions, not a location one can revisit.

Thus, RST rules out time travel: there is no external timeline to move along, only the ongoing, entropic unfolding of the substrate itself.


📌 Conclusion

The RST main equation balances the substrate’s internal dynamics with external sources of stress and information. It shows that time is emergent, infinitely divisible, and inseparable from the eternal present. In RST, the arrow of time is not a path to be traveled but the shadow cast by the substrate’s irreversible drive to dissipate tension.
