Black Holes Essay

Black Holes A black hole is a region of space that has so much density, and such a great gravitational pull, that no nearby objects can escape. Black holes also have a horizon; if you stay outside the horizon, you'll be safe, and the black hole can't suck you in. The line of singularity is an important part of black holes. It's a region in a black hole where matter is crushed into infinite density. The pull of gravity is very strong, making the black holes mass become compressed into a space with zero volume. Some people worry about the sun becoming a black hole, but there's no way that could happen because only stars that weigh considerably more than the sun can become black holes. Black holes still aren't perfectly clear, but scientists will continue to investigate, and find more information on our universe and all the mysteries in it. To find a black hole, scientist’s measure how much mass there is in that area. It’s likely that there’s a black hole there if there’s a large mass concentrated in a small volume and the mass is dark. Also, if the object’s mass is more than three times the sun’s mass, it is labeled a black hole. Scientists have discovered black objects with mass more than ten million times that of the sun. Nobody knows for sure what these are, but scientists are beginning to wonder if these black objects are at the center of every universe. There are many theories regarding black holes. The two I researched were The Stephan Hawking theory of black holes and the 2012 black hole theory. The Stephan Hawking theory of black holes states that black holes transforms what goes into them, but after the black hole disappears, the transformed objects are sent into space. The other theory I found is the 2012 black hole theory. This theory says that a black hole will swallow up the Earth in 2012. There are two endings to this theory. One is that the Earth would be thrown out of its orbit, and we would burn up or freeze to death after a span of two weeks to two months. The other ending shows our deaths coming quicker. As the black hole neared the Earth, the weather would become unpredictable. The atmosphere would disappear, and everything would turn to little pieces. These pieces would keep getting torn apart until nothing was left. With either ending to this theory, we would all end up dead. I think that the Stephan Hawking theory makes the most sense because I don't think that the world will end in 2012. This theory also makes sense to me because it states that a black hole transforms things that it sucks up, and then spits them out when it evaporates. This is what I imagine a black hole doing, so this theory makes sense to me.

Black Holes
A black hole is a region of space that has so much density, and such a great gravitational pull, that no nearby objects can escape. Black holes also have a horizon; if you stay outside the horizon, you'll be safe, and the black hole can't suck you in. The line of singularity is an important part of black holes. It's a region in a black hole where matter is crushed into infinite density. The pull of gravity is very strong, making the black holes mass become compressed into a space with zero volume. Some people worry about the sun becoming a black hole, but there's no way that could happen because only stars that weigh considerably more than the sun can become black holes. Black holes still aren't perfectly clear, but scientists will continue to investigate, and find more information on our universe and all the mysteries in it.
To find a black hole, scientist’s measure how much mass there is in that area. It’s likely that there’s a black hole there if there’s a large mass concentrated in a small volume and the mass is dark. Also, if the object’s mass is more than three times the sun’s mass, it is labeled a black hole. Scientists have discovered black objects with mass more than ten million times that of the sun. Nobody knows for sure what these are, but scientists are beginning to wonder if these black objects are at the center of every universe.
There are many theories regarding black holes. The two I researched were The Stephan Hawking theory of black holes and the 2012 black hole theory. The Stephan Hawking theory of black holes states that black holes transforms what goes into them, but after the black hole disappears, the transformed objects are sent into space. The other theory I found is the 2012 black hole theory. This theory says that a black hole will swallow up the Earth in 2012. There are two endings to this theory. One is that the Earth would be thrown out of its orbit, and we would burn up or freeze to death after a span of two weeks to two months. The other ending shows our deaths coming quicker. As the black hole neared the Earth, the weather would become unpredictable. The atmosphere would disappear, and everything would turn to little pieces. These pieces would keep getting torn apart until nothing was left. With either ending to this theory, we would all end up dead. I think that the Stephan Hawking theory makes the most sense because I don't think that the world will end in 2012. This theory also makes sense to me because it states that a black hole transforms things that it sucks up, and then spits them out when it evaporates. This is what I imagine a black hole doing, so this theory makes sense to me.
Even though scientists are still trying to find information on black holes, what we know so far has given us opportunity to learn and research. While researching black holes I learned that they aren’t quite as monstrous as people think. I also learned about the line of singularity and the horizon of a black hole. Overall, I learned a lot about black holes from this project, and as scientists continue to research, I will learn more.
