Theory of relativity is the extended version of Newton's gravitational law. Newton's theory couldnot explain the gravitational interactions at very high velocities. It was developed by Albert Einstein. According to the theory of relativity, when a body moves with the velocity v, then its mass
m=(mo)/(1-v^2/c^2)^1/2
where m = is the mass of the body in motion,
mo is the mass of the body at rest.
c is the velocity of light.
Similarly time t=to/(1-v^2/c^2)^1/2
and length l = lo/(1-v^2/c^2)^1/2
The two main laws of the theory of relativity are
1. The velocity of light remains constant in all frames of reference.
2. The laws of physics is same in all frames of reference.

General relativity was developed by Einstein in the years 1907 - 1915. General relativity replaces the global Lorentz symmetry of special relativity with a local Lorentz symmetry in the presence of matter. The presence of matter "curves" spacetime, and this curvature affects the path of free particles (and even the path of light). General relativity uses the mathematics of differential geometry and tensors in order to describe gravitation as an effect of the geometry of spacetime. This theory is based on the general principle of relativity, which requires all observers to experience the same laws of physics, not just those moving with uniform speed, hence its name.

basically it is a theory of space and time. it unifies space and time in a single entity called space-time. this theory helps to explain the time dilatation, length contraction and mass increased of an object that is moving. it is based in postulates such as the postulate that i loved is that all observers will always measure the speed of light to be the same no matter what their state of uniform linear motion is. and of course it has a consequence the so called E=mc2 equation.
btw is this homework? because i see too many questions regarding this theme... hahaha
good luck... i hope you get it

i think it has something to do with traveling through space.
correct me if im wrong but i think it means that time is relative for certain spaces.
if a space could travel fast enough to reach closest habitable planet, two weeks would pass on space shuttle.
on earth, 50,000 years would have passed. i saw it on the history chanel

If you have something good for dinner, your relatives will show up to help you eat it.

I'd be glad to explain it to u however I'm not Albert and would no doubt do it an injustice http://answers.yahoo.com/question/index?qid=20060623114902AAQ8qLp
