Black Holes

A common theory states that Black Holes are formed when a star reaches the end of its life, and crushes under its own gravity, leaving behind a compact Black Hole. According to http://burro.astr.cwru.edu, Stephen Hawking has a theory that trillions of Black Holes were created by the Big Bang and that they still exist, however, this theory isn't widely accepted.

Three Main Types of Black Holes

1st is an Electric Black Hole, also known as a 'Charged' Black Hole, which is an electrically charged Black Hole

2nd is a Kerr Black Hole, also known as 'Rotating' Black Hole, which is when two Black Holes merge together

3rd is called Schwarzschild, which is the one we are most familiar with, which is the non-rotating Black Hole.

But no matter what type of Black Hole it is, they all have the same structure, "there mass is concentrated in a small point called the singularity, and is surrounded by ergospehere"

What is a Black Hole?

A Black Hole has a gravity so strong, anything that enters, can't escape. The opening of the Black Hole is known as the 'Event Horizon,' It's also the distance were nothing can escape.

Spinning Black Hole

It's possible for two black holes to live next to each other, but soon enough the larger one will 'cannibalize' the smaller one, creating the Spinning Black Hole

So, how are they studied?

Although Scientist can't actually 'see' them on Earth, they know they're there because of their effects happening around it. They can eat stars, or move them at very high velocity. However, the Hubble Space Telescope can see very dim lights billions of light years away. Now you may be asking 'why don't we just study it from Earth.' According to nasa.gov, the Earth's atmosphere blocks lights from telescopes on Earth.

Random Facts

The name Black Hole was given by John Archibald Wheeler (American)

Black Holes are very hard to observe because they have no light

The largest Black Hole has the mass of 14 billion Suns

The youngest Black Hole is named W49B
