Wait till you get a load of supra-string theory! It treats the strings as macro components of space time rather than micro. We are within one of six, the one that patterns for our specific type of atom. The others pattern for two heavier quark densities of matter and 3 anti-matter charge arrangements.
So the ratio of our matter type to the other hidden or "dark" types works out 1 to 5.
It takes the perspective that a total universe is "spectrumed" apart like a rainbow from light rather than an explosion of junk. Our type of matter is like the orange band....it does not appear independent of the other colors.
This is why I leave the bleeding-edge research to the geniuses and just sort of hang on to what I do get until the new stuff filters down to a level my poor but interested brain can handle.
String theory, in broadest outline, I have -- the idea that everything is composed of even easier stuff than electrons and quarks, just different vibrations of one-dimensional strings making two-dimensional sheets as they move through spacetime. I can wrap my brain around that, though I need a little duct tape to hold it in place. Much beyond that, though, it gets fuzzier than the lettuce I forgot about in my fridge drawer.
In any case, string theory is too new for there to be much consensus on how it works, much less whether it's the path to unification. It may prove be in the long run, or it may just be a mathematically useful way of treating things until a better theory comes along. And it has nowhere near the confirmation of the theories of General Relativity, Quantum Mechanics, and the Standard Model. So I'm willing to sit back and let the whole string thing shake itself out until a clearer picture emerges.
