An international team of astrophysicists with the participation of the University of Zurich proposes a novel method to detect pairs of the biggest black holes found at the centers of galaxies by analyzing gravitational waves generated by binaries of nearby small stellar black holes. The research is published in the journal Nature Astronomy.

    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?
