How Gravity Affects Time, Light, and Space    Gravity is a force that is created by matter with a profound mass and also it must need to have a radius. We, on Earth, can feel the gravitational force that "holds" us done to the Earth so we don't "fall" off of the planet. The moon affects our planet's water tides, and the moon is pretty small compared to the size of Earth too. But in comparison to the whole universe, none of these small things have the ability to make that profound of a difference like other phenomenons out there do. Take for example; a star that is slowing die, it burns out and begins to "pull" itself inward, compressing all of its mass within a small radius, to where it will have a mass over 1000 times that of our sun and a radius the size of Fairbanks! The gravitational force formed by this is huge, so big that it takes an escape velocity that needs to be faster than the speed of light! That is why they are know as black holes because the gravitational force is stronger than light so no light can escape it, it is Black. http://www.townschool.com/NTP/student/child/blackh3.html The only way that they can detect something of this strange phenomenon is by watching what things around this hole do, how it affects near by objects. It will pull particals into it and also star will begin to orbit something that is unseen, that means there needs to be something there to cause the star to do this. Now come the theoretical parts. If you can imagine a three-dimensional plane that is like a trampoline with something that is sitting in the middle of it with an incredible mass, it will look kind of look like a tornado. http://www.tornado.com As the wall of the "tornado" get steeper and steeper due to the large mass in the center the degree of the incoming right before it gets real steep will reach out very far over the plane. This can pull this into it and help hold things together inside a galaxy, forming space to hold it in complete balance. But as you come closer to the center, the gravitational force increases, so much that even light cannot escape. How this refers to time is simple. Back in the "Einstein Theory" I stated one of his equations, dt = dt' . (1-C^2/v^2)^1/2 this means that the closer you come to the speed of light in respect to Earth, the closer time stands still with respect to Earth or any same object. So inside of black hole, in theory, there is no time, it is either stationary, or completely different than what we are used to altogether. Nobody really knows, it's all in theory about what we think what is in there.
