We should all stop joking in this thread. I'm starting to think we don't understand the gravity of the situation.

That's pretty amazing. I thought that interferometers were nifty before but I had no idea one so precise was possible.

I know, it seems surreal what they can do, but they even cool the optics way down to reduce the noise.

They talk about 1/1000th of a proton!

Keep building enough of those things and eventually you will have an imaging  interferometer of such power as to allow us to look up the skirt of Galactic Queen Alura.

If the Queen's undergarments have a sufficient rapidly varying Quadrupole moment, sure!

Going serious, reluctantly, I'm assuming they've simulated the expected signal emitted by 2 BHs spiraling towards their mutual doom and have managed to detect a signal rather similar to that.

I wonder if the 2 masses were substantially different from each other if that might be discerned? I'm trying to imagine the swirly wibbly wobbly waveform from that and am getting sufficiently dizzy as to think a meclazine tab might be called for . . .
