TOP 10 STRANGEST THINGS IN THE UNIVERSE
10. Hypervelocity Stars If you've ever gazed at the night sky, you've probably wished upon a shooting star (which are really meteors). But shooting stars do exist, and they're as rare as one in 100 million.. In 2005, astronomers discovered the first "hypervelocity" star careening out of a galaxy at nearly 530 miles per second (10 times faster than ordinary star movement). We have ideas about what flings these rare stars into deep space, but aren't certain; anything from off-kilter supernova explosions to supermassive black holes might be responsible. 9. Black Holes Speaking of black holes, what could be stranger? Beyond a black hole's gravitational border -- or event horizon -- neither matter nor light can escape. Astrophysicists think dying stars about three to 20 times the mass of the sun can form these strange objects. At the center of galaxies, black holes about 10,000 to 18 billion times heavier than the sun are thought to exist, enlarged by gobb
