From my understanding as a layperson, using other LIGO style detectors to substitute the z-axis won’t work. You need to shoot laser pulses continuously and in sync into two axes from the same detector to be able to detect ripples in spacetime. The sensitivity of two non-connected detectors working together is not high enough. See [1] for how the detection works.

- Already__Taken 9y agoGiven the size of the wavelength is multiples of the earth are they not able to sync up the section of the wave being measured and deduce further measurements from there? You couldn't add 1 axis of another detector as a 3rd leg but having 3 measurements on 3 planes from 3 pairs of beams due to their positions on earth should. Each stations 2 axis measure 1 plane, and you build the 3 plane from the positions on the earths surface. Wouldn't the relative velocities of the earths spin, orbit and the solar systems velocity from the gravity wave origin all make the above measurements... difficult. Or all things considered, the angular tiny velocity from the origin makes that irrelevant. Physics is hard.
- cryptonector 9y agoLIGO is an interferometer. Light is made to interfere with itself. You can't integrate results from other LIGOs to recover the Z dimension because you'd be missing the requisite opportunity to interfere light traveling across that arm with light from the others.
- vpribish 9y agoOther detectors around the surface of the globe will be oriented on different planes. The two we have now give error-rejection and, I suppose 1-D detection. Add another in Europe and one in Australia, do some trigonometry, and bob's your uncle, no?
