Special Relativity is Einstein's theory relating time and space together. It explains a few things including Lorentz contraction. A somewhat mysterious feature is elimination of the idea of a fixed distance between locations and a fixed duration between events. One can never tell if one thing is closer than another is or if one event happened before another. One of the consequences of this is that as one's velocity increase's, the distance to objects along the line of travel seems to contract. And that time seems to slow down.

The momentum of an object increases as it goes faster. If we apply the rule of p*x=h here, what happens? Assume that an object has a fixed momentum in the tiny dimension of p. If the particle has an equal amount of momentum p in normal macro space, the particle has a vector sum total p of 1.414. This would shrink the dimensions so that they seem to be .707 as long as they were before. The relativistic mass of this particle is 1.414 and is traveling at v=0.707c. These are the same values that special relativity arrives at, which is no coincidence. This theory is a result of studying special relativity equations. The momentum addition and special relativity formulas can be shown as identical. This special relativity contraction is used to explain the reason particle mass warps normal space to create gravity.
