This Black Hole Is Too Old for the Universe #space #astronomy #cosmos

[00:00:00]This black hole was too old. [music] Black holes need time. Even at maximum growth, billions of solar masses take hundreds of millions of years.

[00:00:09]>> [music] >> This one existed just 770 million years after the Big Bang, already 2 billion [music] times the sun's mass. It shouldn't have been possible. To reach that size, it would need continuous feeding from birth.

[00:00:21]No pauses.

[00:00:23]No limits. [music] But radiation pressure should slow that growth. That's the boundary.

[00:00:29]So, either [music] it started from a massive seed, far larger than our models predict, born already heavy in a young universe, >> [music] >> or black holes can grow faster than physics allows, and we've underestimated how violent [music] the early universe was. And we still don't know which one is true. The math strains, [music] the timeline compresses. Something happened in the first billion years that we don't fully understand. If one black hole formed too early, [music] how many others are older than they should be?

[00:00:57]Maybe the universe didn't start slowly.

[00:00:58][music] Maybe it began with something already ancient.
