What an ambitious emerging field of research! Anyone else as into this as I am? http://en.wikipedia.org/wiki/Gravitational_wave_astronomy The LISA and LIGO projects are MIND-BLOWING. I can't believe I am so lucky as to be alive in this age. There's never been a better time to be alive. I could just imagine the look on Galileo's face as someone told him, "Yeah, in a little under 400 years astronomers are gonna build a massive device that can detect gravitational waves using three spacecrafts arranged in an equilateral triangle to form a giant Michelson interferometer, with arms about five million kilometers in length. Whats astronomical interformetery, you ask? Well thats about 150 years from your time and that involves..." And on and on and on.
