yeah, I’ve heard the idea, it’s basically turning gravitational waves into a riff – kinda like a cosmic bass loop, but the timing is weird, the frequencies are in the tens of hertz, and the waveform is more like a chirp than a steady beat. still, if you can sync a guitar amp to LIGO data, you might get that “whoosh” before the final plunge. good luck, and remember to keep a tally of how many supernovae you can riff off – that’s the real tracklist for me.
