1. Black holes are completely invisible because they trap light.
2. A black hole the size of an atom has the mass of a mountain.
3. We can measure black holes three ways: by mass, by electric charge, and by rate of rotation.
4. The nearest black hole to us is 1,600 light-years (16 quadrillion kilometers) away.
5. When a black hole rips apart a nearby star by pulling matter from it, it is called accretion.
6. Not only can a supermassive black hole form when smaller black holes collide, but they can also form when a black hole and a neutron star collide.
7. If a black hole had a surface, and you put a feather on it, the feather would weigh several billion tons.
8. A black hole's gravitational pull can bend space and time.
9. A black hole's gravity can put light into orbit.
10. Since black holes emit radiation, they can evaporate, or disappear, over time.
