We Came in With a Bang, But How Are We Going Out? Guest: Katie Mack, Assistant Professor, Physics, North Carolina State University, and author, “The End of Everything (Astrophysically Speaking)” Some say the universe will end with a big crunch—all the planets and galaxies being pulled together in a kind of hot and sweaty reverse-Big-Bang. Most astrophysicists, however, think it’s going to be much colder than that. Colder and darker. Katie Mack joins us to talk about the ways the universe could end. How to Die in Space Guest: Paul Sutter, author, “How to Die in Space: A Journey through Dangerous Astrophysical Phenomena”; astrophysicist at Stony Brook University and The Flatiron Institute; and host, “Ask a Spaceman!” podcast If you find yourself outside your space ship, cosmic forces can lead to spaghettification of the human body (and yes, it's as gruesome as it sounds). But investigating ways to die in space is really a tongue-in-cheek introduction to the fantastic power of the cosmos.
