Albert Einstein

With some characters like Guinan and Dr. Cochrane having experienced or met some people from the future before the future comes to pass, at least according to their articles here, I've thinking about Albert Einstein's theory of how time is all relative. Do any of you at all suppose that in at least the Star Trek universe, that theory could be proven correct due to those individuals' encounters with those incidents? It's a long shot by far, but I'd like to hear what you all have to say about this.
