Short Wave: An Astrophysicist On The End Of Everything

Today, we contemplate the end times — as in the end of our entire universe — with astrophysicist Katie Mack.

The North Carolina State University researcher just released her first book, The End of Everything (Astrophysically Speaking).

Spoiler alert: the names of our possible ends are just as gnarly as the scenarios themselves. Mack’s book discusses many, but our discussion focuses on the following:

  • Heat Death
  • Big Crunch
  • Vacuum Decay

This episode was produced by Rebecca Ramirez, edited by Viet Le and fact-checked by Berly McCoy.
