GEO600 starts continuous search for Gravitational Waves

The joint German-British Gravitational Wave Detector GEO600 has now entered an 18-month run of continuous measurement. Researchers are optimistic that they will be able to observe a never before seen phenomena the Gravitational Wave which is one of the great untested predictions of Einstein's General Theory of Relativity. Gravitational Waves can be used to do "ark astronomy", studying those aspects of the Universe for which ordinary astronomy using light (and the rest of the electromagnetic spectrum) can provide limited information.
