Why we (probably) aren’t living in a computer simulation
An international team of mathematicians argues in a paper in the [[Journal of Holography Applications in Physics]] that the idea we live inside a computer simulation is not merely unlikely but logically impossible: they combine insights from quantum gravity with Gödel’s incompleteness theorem to claim that any physically complete theory of everything cannot be produced by purely algorithmic computation. Lead authors such as [[Mir Faizal]] ([[University of British Columbia]]) and co-author [[Lawrence Krauss]] say the fundamental level of reality requires a “non-algorithmic understanding” beyond computational rules, so no simulation running algorithms could reproduce it. Critics including [[Melvin Vopson]] counter that the argument conflates internal and external rules and neglects simulations operating on higher-order physics, leaving the debate open despite the paper’s bold claim.
