The European Space Agency has launched a probe that is designed to help prove an idea developed by Albert Einstein a hundred years ago: the existence of gravity waves. Dr David Robertson, research fellow for the Institute of Gravitational Research at the University of Glasgow, has been working on this project for 10 years. And was on BBC radio 4 this morning. Fantastic. I recorded it. Glimpsing the data within a black hole by analyzing the gravity waves rippling out of it sounded tantalizing, and was very poetically put (see this post's title).
