Mystery Solved: How Black Holes Grew Massive Quickly?

Huge black holes growing rapidly after the Big Bang, defying what we know about physics. Scientists just found out how they did it. These supermassive black holes, living in the early universe, became huge by gobbling up matter really fast, like gluttons in a buffet. This eating frenzy is special because it exceeds a limit called the Eddington limit, which usually stops black holes from getting too big, too quickly. A team of researchers looked at 21 of the earliest known quasars, using powerful telescopes like XMM-Newton and Chandra. They discovered that these cosmic giants ate so much, so fast, they went beyond the usual rules. The secret lies in the super-Eddington phase, where they devoured matter like crazy.This intense feeding linked the speed of winds coming out of the quasars to the temperature of nearby gas. Cooler gas meant faster winds, while hotter gas meant slower ones. This clue helps explain how these giants grew so big, so early in the universe's life. It's like they found a way to break the speed limit and reach their immense sizes in a hurry. The findings were published in Astronomy & Astrophysics, giving scientists a concrete clue to one of the biggest questions in modern astrophysics. It's like solving a cosmic puzzle, one piece at a time.
