All true, so far as we know. And that is the rub. Recall Lord Kelvin, who in the late 1800's proclaimed that everything to be known in physics had been discovered, the only thing left was finer and finer measurement of physical values. Along comes Einstein, Heisenberg, et al a few years later to turn his notion on its head. Discovery is a random but wondrous thing. Who knows when it will happen, who knows where it will lead? I surely don't.
One of my own interests has always been the TOE, which no one has successfully explained. String theory? Nice try, I think, but not a viable solution. Occam's Razor should be a clue. Maybe. An eleven dimensional universe makes little sense to me. But, what do I know? Not much.
