I can't recall what I said before, but it *has* been done in the backyard before. There's good news and bad news. The good news is that all the software for processing your data: coherent dedispersion, folding, moving all arrival times to the solar system barycentre, Einstein delay, Shapiro delay,

First, a picky - but important - point. There is a difference between "gravity waves" and "gravitational waves". When you go to the beach and watch the waves crash on the shore, that's an example of a gravity wave. Now, onto the far more interesting topic of gravitational waves and my pet topic, p

way way way left. Ray Weiss was the speaker at the Stanford Physics Colloquium today. In case you don't recognize the name, he is one of the leaders of the LIGO project that detected gravity waves about a year ago. He's a good speaker with a neat topic. He spent a lot of time giving credit t
