Computing a Universe Simulation
Summary
This episode explores the computational limits of the universe, calculating the memory and processing power required to simulate reality within itself. Hosts discuss the Bekenstein bound and Margolus-Levitin theorem to estimate that a black hole the size of Switzerland could store all universal information, though reading results via Hawking radiation would take eons. The discussion also covers recent gravitational wave findings, explaining why light arrived slightly after gravitational waves due to intergalactic medium interactions and merger dynamics.
