It'll probably be a while before we address M-Theory, if ever. We really want to focus on things in the Universe that we have evidence for. In fact, I'm perfectly happy to focus on evidence without theories. But I'm hesitant to do the opposite. String/M-theory has some interesting math, I'm told, but it's way beyond me to explain it. But the bigger problem for me is that there just isn't any evidence for it... yet. As soon as an experiment comes out that can start testing some of these String-based theories, we'll get started trying to explain it to people.

If you want more information on String theory, definitely give Brian Greene's books a read, or watch his special on Nova. I think the episodes are even watchable on the Internet.
