I haven't heard quite that argument before. Couldn't it just be simulated slower than real-time? Or is memory the issue?

- psyc 10y agoRegarding "Basic Thermo", everything we 'know', we subjectively acquired over a tiny period of time, through a game of telephone that refers to the current universe. We're really in no position to comment, in absolutes, on the nature of the parent universes.
- snowwrestler 10y agoIn order to simulate anything you have to expend energy and create entropy to power the simulation. But to be completely accurate, a simulation must include all the energy expenditures and entropy of the system being simulated. So the math can never add up.
