Could We Create Artificial Universes? Narration Only)
Summary
Isaac Arthur explores the theoretical possibility of intelligence creating artificial universes, distinguishing between dependent simulations (subverses) and independent baby cosmoses (seedverses) born from black holes or false vacuum bubbles. The episode examines the technical pathways for cosmic engineering, from massive computational substrates to manipulating spacetime, and contrasts the ethical responsibilities of maintaining a simulation versus the permanent separation of a physical offspring. Arthur also considers how such capabilities might explain the Fermi Paradox, suggesting adva…
