Astronomers have found a background din of exceptionally long-wavelength gravitational waves pervading the cosmos. The cause? Probably supermassive black hole collisions, but more exotic options can’t be ruled out.

Without reading the article, is this just a new discovery that was always there? Or is this a new sound that just appeared on the radar?
I read a similar article yesterday stating this was a conclusion recently arrived at after of decades of collecting and reviewing data on the distance between our telescopes and sets of “calibration” quasars and calculating differences in the actual and expected distances over time.
Always there. Here’s an ELI5 from Bing:
Much appreciated. Thank you.
I’m Glad it’s not some new sound.
The discovery is new, why not just read the article instead of relying on some AI bullshit?
