Black Holes

By Neel Patel

What are Black Holes?

Black Holes are locations in space where gravity is so strong that not even light can escape. Matter from stars dying has been squeezed into an very tight space which causes extreme gravity. The density from the star is unbelievable and the black hole is formed.

How do Black Holes Form?

When extremely large stars (about 20 times the size of our sun) die they have the chance to create a black hole. Usually stars are able to balance their gravity and pressure but towards the end of its life it will run out of nuclear energy and it will be compressed into a black hole. This is very different from how small stars die because they die peacefully due to their inside pressure halting gravitational collapse. Another event that can take place when very large stars die is a supernova. If the core in the star is massive enough it will collapse in on itself and explode.

What Would It Be Like In A Black Hole?

There are many different theories as to what could lie inside of a black hole. Some believe that they are doors to new universes or wormholes. Although, it is widely thought that if one were to fall into a black hole they would be ripped apart, fried, or trapped forever. If not even light can escape a black hole, then humans are not likely to be able to.

Are We Living In a Black Hole?

There are many unanswered questions when it comes to how the universe began. The theory that we live in a black hole answers answers these questions. A slightly modified version of Einstein's theory of relativity explains why neutrinos spin asymmetrically and go from matter to antimatter so often.

Is A Black Hole A Wormhole?

There is not a lot of evidence to suggest that black holes are wormholes, but some believe that black holes are entrances into wormholes. Wormholes are a hypothetical connection between widely separated regions of space time. Some astronomers believe that one massive black hole may be the entrance into a wormhole but that is only speculation.

Can You Go Through A Black Hole?

It is not known whether or not you can pass through a black hole, but the evidence points to the answer being no. Black holes aren't really holes. They are orbs with an incredible gravitational field. If somebody were able to enter a black hole you would see them fall more and more slowly but never reach the event horizon. This is an optical effect due to the paths of the light rays.

Fun Facts!

1. There are different types of black holes: spinning and electrical.

2. Black holes are so dense the mass of Earth would only take up 9 millimeters inside of one.

3. Black holes actually make noise because the energy of motion transfers into sound waves. This sound is similar to the sound that is made when a bath drain is unplugged.

4. The gravity of a black hole is so strong that it slows down and even freezes time when it gets close to the horizon.

5. Since black holes turn matter into subatomic particles, they could create elements like iron and carbon.
