Summary

In this episode of Crash Course Pods: The Universe, Dr. Katie Mack and John Green discuss the future of the universe, starting with the near-term fate of Earth. They cover topics such as asteroid impacts, solar flares, and the gradual changes in Earth’s rotation and the Moon’s orbit. The discussion then moves to the Sun’s evolution, explaining how it will become brighter and eventually a red giant, leading to the boiling of Earth’s oceans in about a billion years. They explore the concept of the habitable zone and the possibility of humanity moving to other planets, but note the challenges of terraforming. The episode concludes with a look at the far future, including the Sun’s transformation into a white dwarf and the eventual end of star formation, leaving the universe in a state of gradual cooling and expansion.
