ELI5: Explain Like I'm 5

Micro black hole

A micro black hole is a tiny black hole that is so small it can fit in the palm of your hand. Black holes are like monsters that gobble up anything around them, including light, stars, and planets. A micro black hole is much less powerful than a regular black hole, so no need to worry about it eating anything in your house. Scientists think that tiny black holes were created during the Big Bang billions of years ago when the universe was just beginning. We can't see them, but some scientists think they exist all around us. They might even be inside us!
