Physics teacher and communicator Gareth Sturdy discusses a major scientific discovery.

Earlier this month, scientists confirmed the detection of

gravitational waves, confirming an important conclusion from Albert

Einstein’s work. But what are gravitational waves and what does their

detection mean for our understanding of the universe?

In this podcast, Gareth Sturdy from The Physics Factory talks to Rob

Lyons about space-time, the Big Bang and the on-going debates in physics

between quantum mechanics and relativity theory.
