Part 3/11:
Following the depletion of stars, the episode emphasizes a potential strategy: purposely hoarding energy and resources for when cosmic temperatures drop significantly. As the Universe continues to expand and cool, computational efficiency could rise dramatically, allowing civilizations to operate under conditions that are vastly different from today's understanding of energy use. The theoretical advantages of running civilization on a low-energy basis, in a dark Universe subdued by entropy, offer a striking perspective on what life might look like—enabling intelligence to thrive even in inhospitable environments.
