How is the universe going to end?

Not to be a downer, but the universe could end any minute. Or it could take a hundred million years. Give or take. So we don't know *when* it will happen, but we can be a bit more certain about *how* the universe will end. In this episode, Tai unpacks the science of the end times. In this episode Tai talks to:  Katie Mack, theoretical astrophysicist and the author of The End of Everything (Astrophysically Speaking), Christopher Kochanek, professor of astronomy at the Ohio State University. His current research focuses on "massive stars behaving badly."
