Black Holes The time machine

Imagine a dark void in space, something impossible to escape from. As it spins and spins its mass reaches over a million suns it's rotation speed is 670 million miles per hour. A black hole can be the new time machine and a great discovery, it can it bring you to another universe. To many people a black hole is a mystery in space or a door to another universe. What is a black hole where or when does it bring you? These questions and more will be answered. Figure out what this mysterious void in space really is.

What is a Black Hole?

A black hole is a force of gravity so strong it can hold in light. The gravity is so strong because the matter has been squeezed into a tiny space so it is very dense. Since no light can get out a black hole it is invisible to the human eye.

Our Sun

Have you ever heard of the theory that the sun will turn into a black hole it's wrong. According to NASA the sun does not have enough mass to become a black hole. That's great for earth because there will be no black hole to suck earth up.

When They Were Discovered

Albert Einstein first predicted the theory of black holes by using the theory of general relativity in 1916. The name black hole was created by an american astronomer John Wheeler. There are three types of black holes: stellar black holes, supermassive black holes and Miniature black holes.

The Different Types of Black Holes

According to N.A.S.A there are three types of black holes: stellar black holes, supermassive black holes and intermediate black holes. These black holes form from the differ of their mass. Stellar Black Holes are formed when a massive star collapses. Supermassive Black holes can have a mass equivalent to a billion suns, usually appear in the centre of galaxies such as ours. Scientist don’t know how a supermassive Black hole is formed but the theory is it is a by-product of a galaxy formation. The miniature black hole has not been discovered but it is possible that it was formed shortly after the Big Bang.

The Theory of Relativity

There are 4 parts on the theory of relativity but the first one is when 2 objects are moving relative to each other. For example If a car is moving 60 miles per hour and there are 2 kids in the back of the car throwing a ball. A kid on the sidewalk observes that the ball is going 10 miles per hour technically the ball in going 70 miles per hour because of the speed of the car and the speed of the ball added together. Nothing on the earth ever stand in the same place because the earth is always moving.”Time is an illusion” as Einstein once said.

Time Machine

If you where to go inside a black all of the gravitational pull and the other forces against you it would flatten you and stretch you. If you were to survive a black hole which is physically impossible with the technology we have it is possible it can bring you back in time. This is because a black hole can reach up to 84 percent of the speed of light but it can go faster. If you go faster than the speed of light the time goes backwards and a black hole can reach those speeds. Though the problem is it would rip you apart in the process.

By now you would definitely not want to go near a black with it’s powerful gravitational pull. Though black holes are a very interesting thing though they are very dangerous and there still undiscovered. Black holes can be the next new big discovery it could be the new time machine.
