=__Black Holes Due Monday__= There are many wonders in space, from stars to planets to galaxies. One of the most mysterious astonishments are black holes. Many people wonder where they come from and why or if they really exist. They are [|created] by massive stars that have died and collapsed. When the star collapses all its matter is pulled back by the stars gravity but the star has no strength to stay a solid structure all the stars matter falls back to a single point this creates a [|singularity]. A point in space and time when gravitational pulls cause matter to have zero volume and space and time become infinitely distorted. Heres an example of what a black hole would be like, imagine all of the Earth's mass in a ball the size of a pebble. It would have the same amount of gravity if you were the same distance away from the center as you are now because it has the same amount of mass the only thing is the earths mass is packed completely together. The closer you get to the black hole the more gravity will be affecting you. Once you come within a certain distance, the [|Swartchild Radius] or event horizon, the gravity is so immense that light itself cannot escape its pull thus nothing can be seen other than black, short for this is [|Event Horizon]. If you were to try and cross this line you would be ripped apart because the difference in force of gravity over just a few meters. Also the closer you get to the center of a black hole the slower time ticks and you will become more red. This is caused by gravity distorting time and space and bending light. How do we know that black holes exist? The light they produce from devouring other planets and stars. They also emit radio waves and X-rays. (First picture is the visible light, the second is x-rays and the third is radio waves.) Since black holes are extremely difficult to observe because of its gravity, there are many theories of what happens if you get sucked into one. One theory is that a black hole is a type of worm hole and when you pass through you come out somewhere else in space and time. First of all if black holes are not actually holes they are bodies in which its matter is a singularity. Secondly you do not get "sucked" into a black hole it is just the immense gravity of the black hole that pulls you in. Thirdly a black hole is 3 dimensional if you were pulled into one there is no way you can be brought out of a [|white hole] in a completely different part of the universe.. The final point I would like to make is if wormholes were to be in existence would we not see the matter "sucked" in a black hole being spit back out by a white hole? In my opinion there is no such things as wormholes or white holes because of all the laws of physics it would break. Evan MacTaggart, Last update June 24, 2007
