Physicists Just Ruled Out The Universe Being a Simulation

A team of physicists led by Dr. Mir Faizal at the University of British Columbia Okanagan has mathematically argued that the universe cannot be a computer simulation. 🌌

Key Argument Against the Simulation Hypothesis

The core of their argument is that the fundamental nature of reality operates in a way that is non-algorithmic, and therefore, cannot be fully reproduced through computation.

• Algorithmic vs. Non-Algorithmic Reality: Any computer simulation, by its very nature, must be algorithmic—it must follow a definite set of programmed rules or logical steps. However, the researchers demonstrated that a complete and consistent description of all aspects of physical reality, particularly in the context of a theory of quantum gravity, requires a deeper, non-algorithmic understanding.

• Mathematical Theorems: The team utilized powerful mathematical frameworks, including Gödel’s incompleteness theorem, to show that certain facets of reality would be computationally undecidable and that a wholly algorithmic “Theory of Everything” is impossible.

• Conclusion: Since the fundamental level of reality requires a non-algorithmic understanding that transcends programmed rules, the universe cannot be, and could never be, a simulation.

This research moves the simulation hypothesis out of the realm of pure philosophical speculation and into one of rigorous mathematical and scientific scrutiny.

For a deeper dive into the philosophical side of this debate, you can check out The Simulation Hypothesis Explained by Nick Bostrom. This video explains the famous philosophical argument that suggests we’re more likely to be in a simulation than in the original reality, which the recent physics research is aiming to debunk.

A question that has vexed physicists for the past century may finally have a solution – but perhaps not the one everyone was hoping for.

In a new, detailed breakdown of current theory, a team of physicists led by Mir Faizal of the University of British Columbia has shown that there is no universal “Theory of Everything” that neatly reconciles general relativity with quantum mechanics – at least, not an algorithmic one.

A natural consequence of this is that the Universe can’t be a simulation, since any such simulations would have to operate algorithmically

We have demonstrated that it is impossible to describe all aspects of physical reality using a computational theory of quantum gravity,” Faizal says.

“Therefore, no physically complete and consistent theory of everything can be derived from computation alone. Rather, it requires a non-algorithmic understanding, which is more fundamental than the computational laws of quantum gravity and therefore more fundamental than spacetime itself.”

These propose spacetime and quantum fields emerge from a foundation of pure information, beyond which nothing exists – described succinctly by American theoretical physicist John Wheeler as getting an “it from a bit“.

Yet there are good reasons, the team says, that “its” can’t come from “bits”.
