How does the universe meet its end? Will it drift into a frozen void, collapse in on itself, or be torn apart by dark energy? In the 3rd episode of The Fundamental Why, Cary and Saahil explore both physics and philosophy: from heat death, the Big Crunch, Big Rip, and vacuum decay to cosmic nihilism, eternal recurrence, and determinism. Can we even know how it ends—and does that knowledge even give meaning to existence? Join us as we close the loop from the birth of the cosmos to its ultimate destiny.
