 The theory of relativity is a very complex theory that deals with general and special relativity, gravitation and its relation to other forces, and velocity of light.

The basic idea of the theory of relativity is that time and space are no different from matter. Gravity is pulling you no matter what direction your going, it just depends on what velocity your traveling at. The theory of relatvity can be summed up with the two types of relativity that exist. The two different types of relativity are, General and Special, that both deal with motion and time. General relativity is an object or system in an accelerated or changing motion. Special relativity is an object or system in a constant motion. The main point of both of them are all about motion and the changing of motion. So that means that motion plays a big role in the theory of relativity. General and Special relativity have to do with the wave centers that travel through space. This causes the difference of the in-waves coming from one side to the other side. To be able to accelerate the wave center would have to not change, but when the in-waves are moving the wave center has to move at a constant velocity. In general relativity, if there is a change in velocity with the waves, this causes a change in the waves going back to the wave-centers which causes the particle or object to move in space. "Time and space and gravitation have no separate existence from matter." -Albert Einstein Gravitation helps in the theory of relativity. Gravitation is the cause for black holes in space. Black holes are just collapse stars that have a strong gravtiational pull, that nothing can escape. Even thought Einstein never believed in black holes, they were still a big part of his theory of relativity. Einstein published that gravity can have an affect on the intervals of time and space. In the equivalence principle it suggests that gravity that is pulling in one direction is equal to an acceleration in the opposite direction. Knowing that, if gravity is equal to acceleration, and motion has effects on time and space, then that means that gravity does as well. Gravity that has any mass can have the affect of warping or changing the space and time around it. There have been predictions of gravitation existing as a whole in the universe. Einstein’s theory suggests that if two items are moving at a constant velocity, how will we know if the items are moving or are not moving. Einstein also suggested that it didn’t matter what physical process was going on, absolute motion at a constant velocity was going to be unpredictable. Einstein proposed that gravity and motion were able to affect the intervals of time and space. Einstein also figured that planet’s in motion can affect the time around them. The velocity of light is not constant, but it is always going to be measured the same. Special relativity has a lot to do with the velocity of light. The theory of relativity has many parts to describe what it is. It is made up of many different components that all come together in the end. Gravity, velocity, special and general relativity all need to be there so that motion can be possible to matter in space. Without it there wouldn't be a theory or relativity. The theory of relativity is a very complex theory that deals with general and special relativity, gravitation and its relation to other forces, and velocity of light.

There is a lot of information explaining how Einstein came to make this theory. It explains a lot of different area's in the theory of relativity. Good site with good information.

This site gets deep into the theory. Starting from Einsteins beginning thoughts of the theory to how the theory was applied to the world. There is so much information on here. It is a very helpful site when looking for a lot of information and pictures.
