As a matter of fact, we know that the four fundamental forces are mediated by bosons; for the strong force, it is the 8 gluons, for the weak force, it is W+,W- and Z sub 0 bosons, for the electromagnetic force, the photon, and obviously the option for the gravitational force lies in the graviton. Of course, we could readily speculate that all of matter is made up of some particle of arbitrary letter X, but blatantly, we would need scientific reasoning and logic behind it.
Ergo the inevitable String theory. Though originally born to settle the account between the general world and the quantum realm, it was as well, and perhaps most importantly, to settle the matter of --- matter. You see, good old physics will never cease seeking the physical mediators of any and all phenomena, and they'll find them too, because of e=mc2 (ahem); If it exists in any form and is manifest in our physical world, then it must shed some of its energy into matter, because this is the physical realm. But String theory really starts grabbing at strings (and this a good thing) when it bypasses the physical world and attempts to look at reality through, for lack of a better phrase, an otherworldly microscope. Therefore unifying and mediating all forms and branches of physics.
String theory is indeed a theoretical framework attempting unify the worlds of quantum mechanics and general relativity, in which point like particles are replaced by strings. There are, however, some alternatives to string theory, chiefly featuring twister theory and loop quantum gravity. As for the palatial twister theory I mentioned previously, it is essentially a variant of twister theory proposed by Roger Penrise, just as hyper Kahler manifolds. Truly, the mathematical reasoning goes over my head. As you can discern, physics is indeed a very intriguing subject, arguably more fascinating than the profound realm of mathematical reasoning. M theory attempts to unify all of the distinct string theories and such notions are generally based upon the Ads Cft correspondence. Compactification plays a vital role in this theoretical framework of string theory, with increasing evidence suggesting that there in fact more than the three space dimensions and spatial dimension. They are curled up into a Calabi Yau manifold, no rigour intended with the terminology ‘cruled.’
