In about an hour I'm heading over to a local Coffeeshop Astrophysics meeting put on by researchers and grad students at UW-Milwaukee. The topic is the gravity wave discovery. Apparently some of them contributed to the LIGO project so it will be interesting to hear what they have to say. I'll update in this thread with any interesting info. http://www.cgca.uwm.edu/coffee/index.html If you have a question, post it here and I'll do my best to get it answered.
