How Will the Universe End?

The video explores the future of the universe, focusing on the eventual heat death and the long periods of darkness that will follow the age of stars. It discusses the degenerate age, where only stellar remnants like neutron stars and black dwarfs remain. The dissolution of galaxies and the role of black holes are examined, along with the potential for proton decay. The video also delves into quantum tunneling and the formation of iron stars, ultimately leading to a universe of diffuse particles and maximum entropy.
