This seems like a thing to build on the moon.

Or even better - make it space based: https://en.wikipedia.org/wiki/Laser_Interferometer_Space_Ant...

Unfortunate to see NASA was forced to withdrawal (for budgetary concerns).

LISA has now been funded by ESA with a small contribution from NASA. It is slated for launch in the late 2020s / early 2030s.

Funnily enough, the moon has recently been used to constrain the gravitational wave stochastic background [1], i.e. the space-time strain created by the stochastic gravitational wave emission of all massive bodies in the universe.

This is actually a plot point in Greg Egan's Diaspora. A moon-based laser interferometer is used to detect an impending neutron star merger that will have catastrophic results for biological life on Earth.
