What are black holes. • A black hole is a super dense object that has an intense gravitational pull. There are two parts to a black hole, a singularity and a event horizon.
How are Black Holes formed • Most common theory is where a colossal star with a mass of more than 3 times the Sun’s reaches the end of its life, gets crushed under its own gravity, leaving behind a very black hole.
If you were to take a slice of a black hole right through its center it would look like this The event horizon is where the force of gravity becomes so strong that even light is pulled into the black hole.
Although the event horizon is part of a black hole, it is not a tangible object. If you were to fall into a black hole, it would be impossible for you to know when you hit the event horizon. For a mathematical derivation of the radius of a event horizon see below.
