Episode description
*Astrophysically speaking. That's the subject of Katie Mack's new book: the possible ends to our entire universe. Specifically, she breaks down some following potential outcomes: heat death, the big crunch and vacuum decay. (Spoiler alert: the names of the other scenarios we don't get to in this episode are just as cool.)Email the show your existential questions at shortwave@npr.org. But please, no existential dread at this time — we're full up on that.
P.S. We're off Monday for Labor Day. So, catch you Tuesday!
