Could We Create Artificial Universes? Narration Only)
What if the ultimate technology isn’t a starship, but a universe? We explore simulated worlds, baby universes, black holes, false vacuum bubbles, and whether civilization could one day create realities of its own.Get Nebula using my link for 50% off an annual subscription: https://go.nebula.tv/isaacarthurEnjoy Rifftrax: https://nebula.tv/rifftrax?ref=isaacarthur🛒 SFIA Merchandise: https:/
