History of GEO600

GEO Diary

Since September 1995 we build the British-German gravitational wave detector. These pages show how GEO600 forges ahead. Here you find the very latest pictures from the detector site and information from our labs.

Predicted by Einstein 100 years ago, gravitational waves have now been directly detected for the first time. The signal of two merging black holes has been found by the LIGO detectors in Hanford and Livingston, USA.
