Myths and Facts of Black Holes.
Black holes have many rumors behind them, such as time travel, or traveling through one, and ending up somewhere else in the universe. Actually though, a black hole is a region of space having a gravitational field so intense that no matter or radiation can escape.
Now knowing what a black hole actually is, we can look at the myths of black holes. One of the most common myths about black holes are that time travel is possible through them. Thanks to science fiction, many people believe this, even though this hasn’t been proven. Even though the theory of relativity states that black holes can warp space time and create black holes, it is nothing but a theory. Another common myth is worm-holes, and being able to quickly travel through a black hole to another part of the universe. This is not true, when an object falls into a black hole, it becomes part of the black hole. The objects never leave the hole. Another myth is that a black hole would devour our entire galaxy. Actually though, due to the space between the stars that the black hole really wouldn’t affect any object, other than those very close.
We do not know everything about black holes, because you can not even get to the edge of one, you would be stretched like spaghetti, tearing you apart in every direction, due to the gravitational force. But we do know some about black holes. Such as, they are cold remnants of former stars. They are made after a star explodes at the end of its life, into a super-nova, then into a black hole. Also, there are different types of black holes, such as, spinning black holes, electrical black holes and even black holes that do both. There are also spinning black holes and regular black holes, which grow by swallowing matter, which spinning black holes are formed by merging the two. Many black can not be directly observed since they are so small, dark and distant. Scientists know the exist by measuring mass in a region of the sky, looking for dark masses. Also, there are many black holes existing in binary star system. These certain holes continually pull mass from neighboring stars, causing the star to completely disappear, while the black hole grows larger. Another fact is that Einstein did revive the theory of black holes in the 1900’s, but originally, it was thought of by John Mitchell, in 1783. Mitchell didn’t continue the theory because he didn’t know what to do with it.
There are many myths and rumors of black holes, yet very few facts. Scientists know very little of black stars due to the fact it is impossible to get close enough to one. Yet, they have found other ways to look and understand black holes.
