Could A Black Hole Mega Burp Wipe Out Life On Our Planet?

The gravitational attraction of a black hole is so strong that not even light can escape it. As a result, black holes are one-way doors in the Universe. No-one knows what goes on inside, except that matter is compressed to an incredibly high density. Because no light can get out, people can’t see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars. Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or “stuff,” in an object. Another kind of black hole is called “stellar.” Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way. The largest black holes are called “supermassive.” These black holes have masses that are more than 1 million suns together. “The supermassive ones”…yes, these are the ones we are going to talk about today!
