Simulation Theory: Quantum Evidence and Philosophical Impact

Locality means objects interact only with their immediate surroundings, while realism means objects possess definite states regardless of observation. Game engines avoid catastrophic computational costs by rendering objects only when the player observes them. In such engines, distance is an illusion because all objects exist as data structures processed within the same computational space. The universe appears to follow identical logic, rendering reality only when information is required.

Experimental Evidence

Thomas Young’s double‑slit experiment demonstrated that light behaves as a wave, and Einstein later showed it also behaves as a particle. Even when single photons pass through the slits, an interference pattern emerges, indicating that each photon traverses both slits simultaneously as a “wave of probability.” Introducing a detector at the slits collapses the wave function, forcing the photon into a definite state. The delayed‑choice experiment shows that deciding to observe a particle after it has passed through the slits retroactively determines its past behavior.

The Nobel Prize and Bell’s Inequality

Einstein advocated hidden variables to preserve a locally real universe, formulating the EPR paradox. John Bell created a mathematical threshold—Bell’s inequality—to test the existence of hidden variables. Experiments by Clauser, Aspect, and Zeilinger consistently violated Bell’s inequality, proving that entangled particles are not separate objects communicating across space but a single system. The 2022 Nobel Prize in Physics recognized these results, confirming that the universe is not locally real.

The Simulation Argument

Nick Bostron argues that if advanced civilizations acquire the capability to run simulations, they will likely run millions, making the probability of living in “base reality” near zero. This perspective frames the universe’s fundamental nature as information processing and mathematics rather than matter and energy.

Mechanisms & Explanations

A quantum particle exists as a set of probabilities until an interaction or measurement captures information about its path, causing wave function collapse and “rendering” a specific state. Entanglement links two particles so that measuring one instantly determines the state of the other, regardless of distance, because they are processed as a single data structure. In a simulated environment, the system resolves past events based on present measurements, effectively changing the particle’s history to match current observation.
