The people at Kurzkesagt did it again, and this time they’re speaking about the biggest black holes in the universe.
You might never hear about the ultramassive black holes. The video takes a look at one at the center of galaxy OJ 287… and it’s so large it can fit 3 solar systems side by side inside of it.
But that’s not the largest. The “king” of all black holes is TON 618. It really shines with a brightness of a hundred TRILLION stars, and 11 solar systems could fit in it.
