Jet wobble suggests close black holes

After studying Mrk 501's core for over two decades with radio telescopes, researchers spotted unusual jet movements and patterns, like a seven-year wobble and a 121-day period, that suggest these black holes are orbiting super close together (just 0.0026 parsecs apart).
This might help scientists better understand the final parsec problem, which is all about figuring out how massive black holes actually get close enough to collide.
Watching this play out could teach us tons about how galaxies evolve.
