“This Mysterious Black Hole at The Dawn of Time Weighs a Billion Suns”

A black hole discovered lurking in the Cosmic Dawn is just way too big to easily explain. Sitting at the center of a galaxy called J1120+0641, it tips the scales at well over a billion Suns’ worth of mass.
Bigger black holes exist all around us today. The problem is the when of J1120+0641’s existence. At less than 770 million years after the Big Bang, it’s hard to figure out how the black hole had the time to gain that much mass.
