We explore what it would take for an advanced civilization to simulate an entire universe, the computational and philosophical hurdles involved, and how such a simulation could be considered a scientific experiment. The discussion touches on Bostrom’s trilemma, quantum fidelity, nested simulations, AI consciousness, and the ethics of creating sentient digital worlds. Ultimately we ask: can the evidence and limits of physics help us distinguish an engineered cosmos from a naturally emergent one? Learn more about your ad choices. Visit megaphone.fm/adchoices
