More than a hundred years after Einstein described gravity as the curving of space and time itself, physicists still can't fully explain what space and time actually are — or why the rules that govern the very large and the rules that govern the very small refuse to agree with each other.

This episode of Deep Sleep Science drifts gently through one of physics' deepest unsolved mysteries: the search for quantum gravity, the strange behavior at the edge of black holes, and the quiet possibility that spacetime itself might not be as fundamental as it feels.

No equations to follow. No need to remember anything. Just a slow, calming walk through one of the biggest open questions in science, designed to ease your mind toward sleep.

Part of Deep Sleep Science. New episodes for restful nights, every week.
