The Universe Itself Might Be Hiding the Gravity Particle From Us
Gravitons, the particle of quantum gravity, may be impossible to detect.
Our Only Chance To Finally Unlock The Gravity Particle
PBS Space Time explores the outer reaches of space, the craziness of astrophysics, the possibilities of sci-fi, and anything else you can think of beyond Planet Earth. Host Matt O'Dowd breaks down both the basic and incredibly complex sides of space and time.
Our Only Chance To Finally Unlock The Gravity Particle
Season 11 Episode 21 | 16m 26s | CC
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.
