Black holes can gobble down matter and spew out vast beams of matter, focused by intense magnetic fields. Black holes are intrinsically cool. Don’t believe me? You should. As evidence, here are two random things about black holes: 1) In the center of every big galaxy lies a supermassive black hole. Our Milky Way has one, four million times more massive than our Sun. 2) Not only that, but there are tens of millions or possibly billions of smaller black holes wandering the galaxy! Never fear, though: The odds of one getting close enough to Earth to do us any harm are so small that the Universe could be a thousand times its current age, a million times, and we’d still never get close to one. But just knowing they’re out there…yikes. And see? That’s cool. There’s something fascinating and forbidding and compelling about black holes. They’re weird, they defy our everyday logic, they’re the ultimate endpoints of matter. But they’re fun, too, which is why I’m so happy to see them as the topic of the latest Symphony of Science—music videos using autotuned scientists. This one is called “Monsters of the Cosmos”:
