High Energy Cosmic Rays Could Give Clues to Whether Our Universe is a Simulation


Quantum chromodynamics is the theory that describes the strong nuclear force, how it binds quarks and gluons into protons and neutrons, and how these form nuclei. Simulating quantum chromodynamics on computers is a way to examine what kind of complexity arises from it. The premise is that simulating physics on such a fundamental level is akin to simulating the Universe itself.
