00:00What if the universe's biggest monsters weren't that big after all?
00:04Scientists just found out we've been overestimating supermassive black holes.
00:08A new study reveals that black holes at the center of young galaxies
00:12might be ten times smaller than we thought.
00:14Researchers used a powerful tool called gravity to weigh one 12 billion light-years away,
00:20and what they found shocked them.
00:22It turns out earlier methods fooled us.
00:25Why?
00:26Because some black holes shoot out intense jets of gas and light,
00:30tricking our instruments into thinking they were way more massive.
00:33This discovery doesn't just shrink black holes.
00:36It could rewrite what we know about galaxy formation and the early universe.
00:40If black holes grew slower than we thought,
00:42our entire model of cosmic evolution may need an update.
00:46So next time you hear supermassive black hole, just remember,
00:49they might not be so supermassive after all.
