"In 2010, before LIGO had been upgraded to its present sensitivity, a textbook chirp that looked like two black holes colliding came through. The team drafted a paper and sent maps of where the signal may have come from to astronomers, who searched for a counterpart with other telescopes. There was just one problem: the signal was a fake deliberately injected into the data stream to make sure the team would be able to spot a real one. The dramatic opening of a sealed envelope revealed that fact to 300 team members in the room, with 100 more watching via a video link."

That LIGO bosses deceived LIGO members is strange, to say the least. That LIGO bosses deceived astronomers and made them waste time and money is unbelievable. Was the 2010 event a failed (for some reasons) prototype of the recent glorious achievement of LIGO?
