The Fate of the Universe and Earth

The video explores the concept of cosmic endings, starting with the inevitable end of everything, including the universe. It explains the Big Bang and the expansion of the universe, leading to the formation of stars and galaxies. The video predicts future events affecting Earth and the solar system, such as extinction events and the sun's transformation into a red giant. It concludes with possible end scenarios for the universe, including the Big Rip, Big Crunch, and Big Freeze, highlighting the role of dark energy in these outcomes.
