Title: Discuss: Gravitational Waves
Post by: thedoc on 25/02/2016 10:55:56

February 2016 marks one of the biggest discoveries in cosmology and astronomy: the LIGO team annouced that they'd detected gravitational waves, 100 years after Albert Einstein predicted them. Scientists believe this could revolutionise how we study the universe. But what are these gravitational waves? How were they detected? And how is the discovery changing our understanding of cosmos?

The programme talks about the two types of gravitational waves, to add to the confusion there are also 'Gravity Waves' which exist in the Earth's atmosphere which are not related. A summary definition from Wikipedia is 'In fluid dynamics, gravity waves are waves generated in a fluid medium or at the interface between two media when the force of gravity or buoyancy tries to restore equilibrium.'
