Gravitational waves explained a little deeper

I discuss the detection of gravitational waves with my wife, Lianne. A very exciting development for this video: Someone has asked if they can add subtitles! No one has ever asked to do this for a video of mine before. So now, thanks to the wonderful Ger Hanssen, this video is more accessible. Just turn on Closed Captions to see his great work.
