In this episode of Talk Nerdy, Cara is joined by Dr. Katie Mack, theoretical astrophysicist and author of "The End of Everything (Astrophysically Speaking)." They talk about the formation of the universe by the big bang, how we know its current trajectory, and possible scenarios for its final destruction. In reflecting on the ultimate eschatological question, Katie and Cara grapple with humanity's quest for meaning in the great beyond.
