PBS Space Time - S2026E03: The Universe Tried to Hide the Gravity Particle. Physicists Found a Loophole.
Physicists have long believed that detecting the particle of gravity—the graviton—was fundamentally impossible, with the universe itself seeming to block every direct attempt. This episode explores a new generation of clever experiments that may finally let us detect gravity’s particle, and why even succeeding wouldn’t quite mean what we think it does.
Cast: Matthew O’Dowd
