Measuring gravitational waves

2 gravity wave detectors have been switched on, trying to prove and discover waves posited by Einstein as part of his theory of general relativity.

The Americans have a huge isolated lab called LIGO (Laser Interferometer Gravitational-Wave Observatory) run by a few people from the LSU and California Institute of Technology in the middle of Livingston Parish, LA.

Britain and Germany have their Geo 600 Detector in Hannover, run by scientists from Glasgow, Cardiff, Birmingham and Hannover Universities.

Apparently there’s also a similar experiment in Japan, but I couldn’t find the links to that.
