> At the very end we may use proton decay to power virtual world running on computers composed of folded spacetime. Subjective time within the simulation can continue no matter how slow the computation looks from the outside. That sounds like pure science fiction. Is there even any theoretical basis for the construction of "computers composed of folded spacetime"?
