The Graviton

The Graviton

The search is still on for a unifying quantum theory of the gravitational force and hopes are pinned on the graviton - a hypothetical elementary particle that transmits the force of gravity. Why is the search for the graviton a major goal of theoretical physics? How will the measurement of gravitational waves and the detection of supersymmetric partners help prove its existence? And how might the graviton unite the seemingly incompatible theories of general relativity and quantum mechanics? This radio broadcast addresses these questions in an interview format. It is 41 minutes and 43 seconds in length.
