interferometer

If the path lengths of these two lasers are the same, but the interferometer reads that the lasers are out of phase, then you have possible warping of space.

Most of the cost is probably in the high-precision interferometer.

Continued work on the ground in the atom interferometer field over longer baselines will explore both.

An interferometer needs to control spacing by a fraction of a wavelength, but for gravitational waves that's like 1e9 m. Optical light is 1e-7m.

Wonder what a space-based astronomical interferometer about the width of the solar system could image?

Gravity wave detectors get phase accuracy by comparing a photon to itself using an interferometer.

And this patent certainly would be in conflict with any software patents that covered the software encoded thereby, if the interferometer were ever put to use in a product.

Barring any surprises, an atom interferometer is much more likely than a timing-based measurement to see any gravitational wave signal.

"I haven't studied the atom interferometer GW stuff in great detail, but the measurements look challenging from a feasibility and systematic perspective.

[5] According to White, a modified Michelson-Morley interferometer could test the idea: one of the legs of the interferometer would appear to be a slightly different length when the test devices were energised.
