Exclusive: Grave doubts over LIGO's discovery of gravitational waves | New Scientist Nov 2018
“We believe that LIGO has failed to make a convincing case for the detection of any gravitational wave event,” says Andrew Jackson, the group’s spokesperson. According to them, the breakthrough was nothing of the sort: it was all an illusion.

Einstein's silence: Listening for space-time ripples - physics-math - 13 April 2014 - New Scientist
The stories/factoids about all the noise they have to compensate for reminded me of a meditation sit. The sensitivity is amazing: "When we were running, we saw storms in the North Sea." Also: "Mysterious, irregular, Doppler-shifted acoustic noise at LIGO-Hanford coincided with arrival and departure times at Richland airport some 20 kilometres away. Then there were the times every few nights in spring when a mysterious noise would roll to a sudden crescendo and ebb away slowly – the rumble of rushing meltwater released from nearby dams."
