5. Roberta Duarte: Four Fates of the Universe
Timestamp: 00:35:34 to 00:38:20 - watch this moment on skim
The ultimate fate of the universe is theorized through four main scenarios: the Big Freeze (heat death), the Big Rip (spacetime tearing apart), the Big Bounce (cyclical expansion and contraction), and the Big Crunch (total collapse). The current dominant theory, the Big Freeze, suggests the universe will continue expanding and cooling indefinitely. The Big Rip is a more extreme scenario where expansion accelerates so rapidly that even atoms are torn apart, occurring almost instantaneously.
