00:00What if a black hole was silently drifting through our galaxy?
00:03Right now.
00:05Scientists at NASA have just confirmed something incredible.
00:08A rogue black hole moving freely through the Milky Way.
00:11With no star system attached, this isn't the giant at the center of our galaxy.
00:16It's a smaller but deadly stellar mass black hole.
00:19The leftover core of a massive star that exploded.
00:23And got flung into space.
00:25And here's the shocking part.
00:26There could be up to 100 million of these invisible objects drifting around.
00:31So how did scientists even find it?
00:33They used something called gravitational microlensing.
00:37The black hole bent light from a distant star.
00:40Revealing itself without emitting any light at all.
00:43This discovery proves one thing.
00:46Our galaxy is filled with unseen giants.
00:49Moving in complete darkness.
00:51This black hole is thousands of light years away.
00:54Poses no threat to Earth.
00:55But it changes everything we thought we knew about space.
00:59The universe is not just vast.
01:02It's crowded with invisible monsters.
01:04We're only beginning to detect.
