Astronomers 1 have discovered the most luminous 2 galaxy 3 ever found, shining with the equivalence of 300 etralion suns from the far side of the visible universe. But almost all that light is been produced by the galaxies 4 century super massive black hole, not by its stars. The inlining finding is in the astrophysical journal. Black holes are black because light itself cannot skip when it’s follow in. But feeding black hole is surrounded by a whirling white hot disk going to bring, material heat its million degrees as its spirons down to bleding, the black hole in this far galaxy sound feeding franse, it produces light to worm up most the galaxy’s dust which gives the whole galaxy an inferend glode that we can attack from 12 half billion light years away. Consider we are seeing this giant black hole activities from time when the universe only attempt present stage. Astronomers are puzzled about how it could grow so big and bright so fast. A young hungry black hole usually takes occasional break from feeding, its glowing can get instance put in some material further away. Think the baby mill, but this particular galaxy is black hole seems to a surcoms vantade this limitation. One theory is that must spilling vary slowly.The slower a black hole spins, the weaker its repulsive burps may be, the longer it can gorge and drop it. Study co-author says the slow spin maybe help the blackhole sustain its binge, which he calls the equivalent of " winning a hotdog eating contest lasting hundreds of millions of years." And there is any mustard with those dogs. Less assured. It's hot.
