Astronomy Picture Of The Day: A Black Hole Just Shattered the Universe’s Speed Limit

A Black Hole Just Shattered the Universe’s Speed Limit Astronomers just watched a black hole do something that was supposed to be impossible.Using NASA’s James Webb Space Telescope and Chandra X-ray Observatory, scientists discovered LID-568 — a black hole in a tiny dwarf galaxy that existed just 1.5 billion years after the Big Bang — gorging on matter at a staggering 40 times the Eddington limit.The Eddington limit was long considered the unbreakable cosmic speed limit for black hole feeding. LID-568 didn’t just break it… it laughed in its face.At “only” 7.2 million solar masses, this black hole is modest by today’s standards, but it’s growing at an absurd rate. JWST and Chandra also spotted powerful, high-speed gas outflows blasting away from it — clear evidence of a violent, chaotic feeding frenzy.This discovery is huge. It could finally solve one of cosmology’s biggest mysteries: how the universe’s first supermassive black holes grew so massive so quickly. The answer? Short, extreme super-Eddington feeding bursts that let them balloon in record time.The early universe was wild.
