What are black holes?
Have you ever wondered what black holes do? Have you ever realized how dangerous they actually are? Have you ever thought about what could create them? Whether or not you have ever wondered about black holes, this essay should be interesting because black holes are very fascinating.
1.How they form.
Black holes form in many different ways.They could be a star that loses all of its energy and finally explodes.It becomes tinier than an atom in less than one second!The gravity turns so strong it pulls in the star right away. It could also be created by two huge stars colliding and one of them starting to spin so fast that its gravity increases to such a high degree that it turns into a black hole.
A black hole can only form out of large things in space. It takes a star at least three times as large as our sun to even be able to turn into a black hole.Did you know that the time the star turns into a black hole takes only a tenth of a second to a fifth of a second?Luckily there is not a star or planet in our solar system that can turn into a black hole but the closest black hole is twenty seven thousand light years away.Since it is that far away it has no effect on earth or any other of our nearby planets.
2.What Can a Black Hole Do to Us?
If a black hole did find a way into our solar system each planet would be taken apart one by one.’’Black holes are God divided by zero,’’ said Albert Einstein.The way that you die from it is you slowly get sucked into the black hole and if you looked back at your friend it would look like he or she is going in slow motion. When they are looking at you it looks like you are going in slow motion.When you get closer to the center of the black hole from the outside it looks like you are slowly stretching out. The gravitational pull is so strong that it is pulling you apart.By then you would be dead because your organs are also stretched out so they would not be able to work any more.
What it would do to our planets is a whole different level.It would take all of the planets out of the sun’s orbit and make the planets crash.It could even be possible that our own moon would crash into our planet.It could also be possible that a planet could just move away from the sun and just float in space and might even eventually go into another galaxy.But that is extremely unlikely because it would probably just get sucked into the black hole and be gone forever. If someday we get the technology to travel to other galaxies, we might get more facts about black holes and about how dangerous they really are. We also would have to take a risk of accidentally going into a black hole while we’re trying to get facts about them, so we would want to create a rocket with large engines that could help us escape the black hole.
- What’s Inside of a Black Hole?
Black holes are made out of three different layers.They are called Outer Event Horizon, The Inner Event Horizon, and the Singularity. Let’s talk about the Outer Event Horizen first. The Outer Event Horizon is the very outer layer. With our technology, we now have a strong enough space rocket to make it out of this layer,but it is very unlikely.
The next layer ( The Inner Event Horizon ) is the layer that it is not possible to escape from – the gravitational pull is so strong nothing can escape it. The very center layer is the the very center of the black hole. The Singularity is the very center of the black hole and it is the most dangerous layer.Its gravitational pull is so strong that nothing, not even light, can escape.A theory that scientists made is that there might be wormholes connecting two black holes together.Wormholes are a way that astronauts could travel to different galaxies a lot faster.
- What Are Black Holes Made Of?
‘’A black hole is a region of spacetime from which extremely strong gravity which prevents anything including light from escaping,” said the website http://www.spaceanswers.com/deep-space/what-is-a-black-hole-made-of/. Black holes’ gravity is so strong because all of the matter is squeezed into a super small space which is less than an atom.Since light can’t get out of the black hole it makes black holes invisible. That is what makes them even more dangerous.That’s why scientists have never seen a black hole.We might think that since black holes are so different they are going to be a different kind of matter. Surprisingly though, black holes have the exact same matter as anything else in space.We could only predict this though because they are so far away it is so hard to get facts about them.
Conclusion
Black holes are one of the most dangerous and mysterious things in our universe. We are lucky to have enough technology to figure things about them, but we’re also lucky that we’re not affected by them. Since there is so much more to learn about them, maybe when you get older you could be an astronomer and you could find out even more about black holes.
