Physicists prove the Universe isn't a simulation after all
sciencedaily.com

New research from UBC Okanagan mathematically demonstrates that the universe cannot be simulated.

This discovery challenges the simulation hypothesis and reveals that the universe’s foundations exist beyond any algorithmic system.
