String theory predicted ten dimensions, but as it got more and more complicated (five theories instead of one), it became clear that what was really need to unify them was eleven dimensions, which had been predicted by another theory, quantum gravity. However, now that both have evolved into M-Theory, that brings me to a basic unanswered question. Is M-Theory really a "unified field theory?" Does it bring gravity into the equation by invoking that extra dimension? If so, how does it unify the electroweak, strong and electromagnetic forces with gravity? I've never heard a simple explanation that didn't require a Ph.D. in Physics.
