What I find nuts it that we don’t know what gravity exactly is, yet somehow we know that there is an invisible field around us that ripples and we can use it to detect astronomical bodies.

“Our idea basically works like listening to a radio channel. We propose using the signal from pairs of small black holes similar to how radio waves carry the signal. The supermassive black holes are the music that is encoded in the frequency modulation (FM) of the detected signal,” said Jakob Stegmann, lead author of the study who started this work at the university of Zurich as a visiting student and since then moved to the Max Planck Institute for Astrophysics as a postdoctoral research fellow.

Am I correct to think that this is, once again, a Fourier Transformation?
