Three giant black holes discovered in a galaxy from the dawn of time
I keep thinking about that 620 light-year gap. In cosmic terms, that's like two people standing shoulder to shoulder at a stadium concert, and they're both about to merge into something even more monstrous. We're watching the universe's early years through a telescope and catching these giants mid-meal.
What gets me is the one growing faster than theory allows. Black holes are supposed to have feeding limits, an Eddington limit where the radiation pressure pushes material away. This one apparently didn't read the manual. If black holes could grow this fast this early, then the seeds of supermassive black holes might have formed much sooner than we assumed, which reshuffles the whole timeline of galaxy formation.
I'd want to know how common this scene was. If three black holes in one galaxy was ordinary back then, mergers like this might be the engine that built the giants we see today at the centers of galaxies. The universe's infancy looks a lot more chaotic and crowded than I pictured.
