The folks Kurzkesagt are at it again, and this time they’re talking about the largest black holes in the universe.
Ever heard of ultramassive black holes? The video takes a look at one at the center of galaxy OJ 287… and it’s so big it can fit three solar systems side by side inside of it.
But that’s not the biggest. The “king” of all black holes is TON 618. It actually shines with a brightness of a hundred TRILLION stars, and 11 solar systems could fit inside of it.
