Sure, I can try. The most important ideas of relativity are three things: that nothing can travel faster than the speed of light, that there is no “absolute” rest, and that the universe is expanding and accelerating.

Has the theory been contradicted or improved upon since einstein's day?

It’s still considered the most fundamental theory of physics, so no, there’s been no serious challenge to the theory. And Einstein himself wasn’t really the first person to propose the ideas, but he was the first to realize how big the implications were.

I didn't know einstein wasn't the first person to propose the idea. Who was?
