Exploring the Fate of the Universe

The video explores the vast timeline of the Universe, from its 14 billion-year history to its potential future. It discusses the concept of time, scientific notation for large numbers, and the five epochs of the Universe: Primordial, Stelliferous, Degenerate, Black Hole, and Dark Eras. The video delves into the eventual fate of stars, the decay of matter, and the evaporation of black holes. It also considers the possibility of a multiverse and a cosmic reboot, offering a hopeful perspective on the Universe's future.
