JWST Finds Black Hole Born Before Its Galaxy, Challenging Growth Theories
TL;DR
Using JWST’s observations of Abell2744-QSO1, scientists directly measured a central black hole of about 50 million solar masses that accounts for roughly 66% of the object's mass just 700 million years after the Big Bang. The finding implies the black hole formed before its host galaxy, challenging traditional growth models that rely on stellar remnants and suggesting a heavy-seed or direct-collapse origin for early supermassive black holes.
