Neil deGrasse Tyson Explains Black Holes

What is a black hole? On this mashup of StarTalk’s best explanations of black holes, Neil deGrasse Tyson and Chuck Nice take us through all you need to know about black holes, featuring Janna Levin.

What happens if you fall into a black hole? We explore spaghettification, high gravity, and how we know if something orbits a black hole. How big is the black hole at the center of our galaxy? Find out about the Copernican principle and how many galaxies have black holes. Discover Hawking Radiation, quantum physics, antimatter, and what goes on at the event horizon. What does a black hole look like inside the event horizon? Is there a loss of information? All that, plus, are there wormholes inside black holes? Is it all an illusion?
