What is a Black Hole?
Black Holes are huge concentrations of matter packed into very tiny spaces. A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing – light isn’t an exception – can leave.
To turn the Earth into a black hole, you would need to squeeze the whole Earth into a tiny marble.

What are types of Black Holes?
Stellar Black Holes
Stellar Black Holes are black holes that were made from a star collapsing in on itself. We’ll divulge into that later on. They are 1-100 times the mass of the sun. Stellar black holes can gain more mass from collisions with stars and other black holes. Most stellar black holes are paired with stars.

Supermassive Black Holes
Supermassive Black Holes are black holes that live in the center of galaxies. They are millions to billions of time the mass of our sun. They can gain mass by feeding on smaller objects like stellar black holes.
