Special relativity is actually quite accessible and really interesting - find a good book or set of lectures on iTunes U or something.
(General relativity, the generalised version including acceleration and gravity, is what makes people think relativity is hard).
I also hope to have an understanding of what it means for a photon to be everywhere at once, from its own point of view.
In the end, I guess I just want to understand the universe just a bit more than I do.
