Difference between LIGO and Michelson-Morley interferometer
The LIGO interferometer looks like a huge Michelson-Morley experiment showing interferences and the gravitational waves are described as waves propagating on the 'spacetime fabric'. LIGO detects ...

Could the Michelson-Morley experiment have detected gravitational waves?
If everything went perfectly and they had no outside noise while conducting the experiment, could they have detected gravitational waves? What would it have looked like to them?

How is the phase gain of a Fabry-Perot resonator for gravitational wave detection derived?
I am trying to understand the use of the Fabry-Perot (FP) resonator in the arms of a gravitational wave detector. A typical explanation is that the gain in power in the arms is equal to $\sqrt{F}$ (...

How does LIGO work?
LIGO is described as working as an interferometer, like a Michelson-Morley interferometer but with many reflections along the arms to increase the sensitivity. In MMs work it was assumed that the ...

Direct observation of Gravitational Waves via increased resolution
First, congrats to the event horizon team for the first photograph of a black hole.
Not to downplay the significance of the photo, but it is a bit blurry. Still, it got me thinking.
One might expect ...

Why is there blindspot for LIGO interferometer?
I am thinking maybe when the gravitational wave hits the 2 mirrors at the same time but the two mirrors are very far apart, so what could be the cause for the blindspot?
