TL;DR

Kurzgesagt dives into the ultimate cosmic doomsday: heat death. As stars wink out, galaxies unravel and black holes evaporate, the universe cools into an inert, eternal void—until they explore a tantalizing “loophole” that might let information (and maybe life) persist against all odds.

They weave together the physics of entropy, black‐hole evaporation and quantum fluctuations, pointing to wild but legit theoretical tricks—think Boltzmann brains or ultra-efficient computation—that could keep something resembling “life” ticking indefinitely.
