The Theory

Our reality is the output of a simulation built in our future—the very same system we inhabit now. Creator and creation collapse into a single, closed causal loop.

Premise

A future civilisation designs a universe-scale simulation. That system is not separate from us—it is our present reality.

Mechanism

The “Big Bang” corresponds to a programmed boot event. Physical law encodes the simulation’s rules; time emerges within the loop.

Implications

Agency flows both ways: our descendants author the system that authors us. Progress in AI and quantum tech is the pathway.

Timeline with present as simulation creation, return to past, and open future cone Past Present Simulation creation (t₀) return / feedback to past Future (open set of outcomes) divergent possibilities forward branching causal loop
The present (simulation creation, t₀) is the intersection: it feeds information back to the past while opening a wide cone of possible futures.
Is this different from a standard simulation argument?

Yes. It specifies identity between the future simulation and our current world, forming a self-originating loop—not merely “a” simulation we’re inside.

What reinterprets the Big Bang?

An intentional initialization event: the moment the system parameters (constants, laws, seeds) are set and execution begins.

Why think this is plausible?

Extrapolations from AI, quantum computing, and scalable computation suggest universe-level modelling may become feasible to our descendants.
