blackholes
Black holes? I know what you are thinking. Something black in space that sucks you in and you can never get out. Even though that is basically true, there is a lot more to it than that. Black holes are the mysterious dark regions of the universe. A black hole is an area of space made up of extremely dense matter in which everything is pulled in, and nothing, not even light, the fastest thing, in the universe can escape. The theory that black holes might actually exist became more common after the 1930's when Einstein gave his theory of general relativity with mathematical formulas. A man named John Wheeler was the one to come up with the name "black hole". Before that, black holes were called "frozen "stars" because of the supposed image of an object entering a black hole would appear to freeze at the edge, even though the object already entered the black hole. The theoretical shape of a black hole is spherical like any other sun or planet. In all black holes, matter collapses into an infinitely den
_____ There are many theories when discussing black holes. One of the most commonly used theories is Einstein's theory of general relativity. The theory basically states that it is impossible to travel faster than light and so it shows that inside a black hole nothing can escape the black hole because to get out an object would have to travel faster than the speed of light. Another formula is the Swarzchild radius, in 1915 by German astronomer Karl Swarzchild, which states the distance from the event horizon to the singularity in a black hole of a certain mass. se point, called a singularity. For example, the radius of a black hole, with the mass of approximately ten suns, would only be thirty kilometers. With the radius of a mass equal to 100 million suns would be three million suns. Black holes have a gravitational field called an event horizon. In this region gravity is so strong that it tugs at space and time, slowing down time and stretching out space. Not even light can escape the immense force of t
