A team of physicists led by Mir Faizal at the University of British Columbia has demonstrated that the universe cannot be a computer simulation, according to research published in October 2025[^1].
The key findings show that reality requires non-algorithmic understanding that cannot be simulated computationally. The researchers used mathematical theorems from Gödel, Tarski, and Chaitin to prove that a complete description of reality cannot be achieved through computation alone[^1].
The team proposes that physics needs a "Meta Theory of Everything" (MToE) - a non-algorithmic layer above the algorithmic one to determine truth from outside the mathematical system[^1]. This would help investigate phenomena like the black hole information paradox without violating mathematical rules.
"Any simulation is inherently algorithmic – it must follow programmed rules," said Faizal. "But since the fundamental level of reality is based on non-algorithmic understanding, the universe cannot be, and could never be, a simulation"[^1].
Lawrence Krauss, a co-author of the study, explained: "The fundamental laws of physics cannot exist inside space and time; they create it. This signifies that any simulation, which must be utilized within a computational framework, would never fully >express the true universe"[^2].
I follow that logic as far as computers today could not simulate this reality. Computers in the far future? What if — and this is a complete ass-pull, so feel free to disregard it as such, but what if — 25,000 years in the future long after the world's dead and moved on, someone pulled some information on the way we were and made a simulation of it, and you're one of them, with no memories of life outside, experiencing what this ancient civilisation experienced?
So maybe science types feel they can rule out the explanation because computer science as they know it doesn't have the capability. But what about alien tech? Future tech?
I'm not a huge fan of the "simulation" theory, but I think ruling it out because it exceeds what we can do now is a bit silly.
