The chapter delves into black holes, discussing their abundance in our galaxy and the universe, as well as the collision of two black holes that produced a larger one. The speakers also speculate on whether dark matter and dark energy could be linked to alien technology beyond human understanding. Additionally, the conversation touches on the universe's expansion and why our galaxy is on a collision course with Andromeda despite the overall stretching of the universe.
Neil deGrasse Tyson, co-host Harrison Greenbaum, and astrophysicist Janna Levin answer questions on the far away and the far out, including Andromeda's impending collision with the Milky Way, white holes, a holographic universe, and more. Prepare to get trippy!
