Cyclic Universes and Bouncing Cosmology - S2:E15
March 02, 2025 · 28 min

Our universe’s initial state was incredibly unlikely, and if it were even slightly different, nothing would exist except for black holes. This episode discusses physicist Paul Steinhardt’s theory of Bouncing Cosmology which attempts to explain this unlikely beginning without requiring either an infinite varied multiverse or an intelligent cause. This theory is so wild and imaginative that we really had to struggle to come up with analogies to make it understandable to everyone. But we did. And these might just be our best analogies yet.
