Gravity Wave Detector Ready For Business

Posted by timothy on from the very-expensive-ripples dept.

Arthur Embleton writes "The BBC has an article about a Gravity Wave Detector. There are two L shaped set-ups. One in Washington, the other in Louisiana. They've got a Laser pointing at a mirror 4km away, watching for the reflection and if it is distorted then it shows that there has been a gravitational pulse, possibly by two Black Holes colliding. The detectors are apparently so accurate they can measure to one-thousandth of the width of a proton! How did they test that it works?"

    How did they test that it works?

    I think that's the problem. These detectors should work in theory, but gravitation waves are so minute when they get to us that it's _really_ hard to be able to get a reading on them. My bet is the first to provide fairly solid evidence of gravitational waves gets a Nobel.
