alt Hacker News>If you are in a sim, then the sim execution is an expensive process, it produces heat and consumes energy.
If simulation theory (or similar ideas) are real, it's entirely possible that the "real world" running the simulation operates on completely different physical laws than the simulation.
Again, this is unknowable if the creator of the simulation doesn't want you to figure out it's a simulation. Simulation or not, this is our reality, and our consciousness would be a simulation inside that simulation. Instead of a weird wobbly space universe, we'd just have an execution platform universe.
