When you question whether Einstein was wrong I assume you mean his theories. Relativity has been confirmed countless times since it was first posited. I am of the belief that, given time (I'd guess late twenty-first century, so within the next hundred years), a new way of thinking will overturn Einstein's theories, but I don't think anyone can reasonably argue that Einstein's theories can ever be said to be "wrong." Newton's laws still apply perfectly well for most activities that happen in every day life. Another theory may overturn Einstein's in the same way Einstein's overturned Newton's, but his laws will still apply.
This is getting off-topic but one new theory I've read about recently is that the universe is composed of information and can be measured in bits (yes it's understandable this would come about during our current age of a computerized society). Discussing black holes, it relates thermodynamics and entropy with information. Another theory suggests the universe is timeless, and that the passage of time is but an illusion. Each new "Now" or moment is but one of a myriad of instants of a configuration space, each different. This later theory actually agrees with general relativity, and the book gets into details on how Einstein didn't go far enough into his own theory. I don't know that I agree with either but I thought I'd share them, cool ideas.
