Black holes

Ka boom! A star explodes with different color streaks of light. Cerulean blue, red, and yellow light streaks burst in different directions. They look brighter and prettier than the 4th of July. The scientists look on their radars and see unusual sightings. Then, they realize that a black hole is being formed. You are in space investigating this black hole. Your partners send you out to investigate, but you look out into space and see light from the stars getting sucked in. You think if your rope snaps you will never see your partners again. There is a queasy feeling in your stomach. You hear the encouraging voices of your partners and you stop for a moment, and finally you decide it has to be done. You carefully tie your rope around your waist. You think this day can’t get any worse, but it does. After taking some pictures you realize that you’re going further than you were suppose to. You turn around to see that your rope broke. You panic, you scream, you shout, but it’s no use. No one hears you. You might appear out of the other side of the black hole –a white hole- or you could appear in another galaxy you know they’re theories. No one can prove it’s true. As you’re speeding through space you get closer every second towards the black hole until you are in it, because of gravity you get stretched until the human race has lost another human being. Black holes are really strong vacuums, which is because of the amazing gravitation pull. Nothing known to man can escape its grasp; not even light. If you think about it carefully, black holes are pretty cool things. In a way black holes are ghost stars because black holes are “dead” stars. Black holes are formed when a star dies, that takes a while but it happens. Hydrogen pushing against the gravity eventually runs out which causes an explosion. The explosion is called a supernova. If it is a giant star and it explodes it will sometimes turn into a black hole, but it could turn into a dwarf star. If the star was a little bit bigger than our sun or smaller than our sun it would turn into a dwarf star. This process is kind of the separation between alive and “dead” stars. If the star was about twice the size of our sun it would probably turn into a black hole another way to explain this would be called the Chandrasekhar limit, this limit says that stars greater than 1.4 times the mass of our Sun will have to go through supernova and eventually turn into a black hole. But there are much more amazing things about black holes like supernova. - Chandrasekhar MThe explosion is called supernova. After the supernova, if the star is big enough the star will turn into a black hole as it is getting smaller it will start to pull gas, dust and asteroids, soon it will be able to pull in larger things like light from stars and humans. Spaghettification is the process of a person getting stretched in a black hole. When you’re in a black hole you get stretched miles long until you snap in half. You will stretch like a long piece of spaghetti. Scientists don’t know it’s true that people get stretched in a black hole, but they are pretty sure of it. Spaghettification happens because the gravity on the per son’s feet is stronger than the gravity on the person’s head. This difference causes the person to stretch. This process is pretty quick, but other processes are long. Black holes die, but it takes billions and billions of years for it to die. It takes a black hole about twice as long to die as it takes a galaxy to die. Since a black hole takes that long for it to die, scientists have rounded it to never. If a black hole was formed when a galaxy was formed it would take a black hole longer to die. Black holes will die when they get really, really, really, tiny. Then they will evaporate, but that takes billions of billions of years. Black holes have a definite life. They get smaller when gravity compresses on them until they evaporate. Like the astronaut that died.
