00:00Imagine a star, bigger than our sun, suddenly ripped away from its galaxy, blasting through
00:04the dark void at an insane 2 million miles per hour.
00:07These are called hypervelocity stars.
00:10They are cosmic outlaws, completely untethered from any galaxy, drifting entirely alone in
00:15the deep universe.
00:15How fast is that?
00:16It's over 400 times faster than a speeding bullet.
00:20At this speed, you could travel from New York to Los Angeles in just 4 seconds.
00:23So what caused this?
00:24A supermassive black hole.
00:26When a binary star system gets too close, the black hole eats one star and flings the
00:31other into deep space like a gravitational slingshot.
00:34Right now, there are hundreds of these runaway stars tearing across the cosmos.
00:38Could one ever hit Earth?
00:39Hit follow to find out in the next video.
