Podcast Extra: Gravitational Waves

For anyone who's still a little fuzzy or confused by the enormity
of the recent detection of gravitational waves by the LIGO
facility, we've recorded a special podcast extra to shed some
light on the impossibly complex world of General Relativity,
interferometry detectors and gravitational waves themselves.


This podcast extra should explain in simple terms:


What gravitational waves are

Why they're so important

How they were detected

What this means for the future of physics & astronomy



With special thanks to LIGO, the National Science Foundation and
Cardiff University's School of Physics and Astronomy.
