Simulation Hypothesis

Simulations by computing needed · 941 simulations

Roughly how much computing a serious run uses today, in operations per second, the Sandbox’s unit. For scale, the observable universe treated as a computer does about 10104. Every figure has a confidence tag, and most are rough.
