I don't think that gravity waves have ever been directly detected by purpose built instruments.

Years ago an astrophysicist told me of an attempt being made to "measure gravity" directly. It was a failure.

Tell Fred Raab at Hanford LIGO (my next door neighbor) http://www.ligo-wa.caltech.edu that it is a failure. Not the same as “not detected yet”.

I guess the machine didn’t work, because it was too heavy.
