Why it is (nearly) impossible that we live in a simulation (arxiv.org)
We assess how physically realistic the ''simulation hypothesis'' for this Universe is, based on physical constraints arising from the link between information and energy, and on known astrophysical constraints.

Gravity is a clue that we live in a simulation (bgr.com)
We all know gravity as the invisible force that keeps us grounded. But what if it’s not a force at all? What if it’s a function? One physicist believes gravity might actually be one of the strongest clues that we live in a simulation.
