Important stuff! But string theory works only if you assume the existence of other dimensions-nine, 11, or 25 of them, depending on your flavor of string thinking-and there’s not one shred of evidence other dimensions exist. In various versions, the theory also seeks to explain how the Big Bang could have been possible, to reconcile the extremely tiny realm of quantum mechanics with the cosmic kingdom of general relativity, and to answer whether the expansion of our universe will stop or continue forever. String theory says that these seemingly amorphous infinitesimal aspects of matter are made from other dimensions, compressed to a smallness that strains imagination. Smash up subatomic particles into smaller units such as quarks, and the quarks don’t appear to have content-puzzling, to say the least. String theory seeks to explain why, at the very minute scale, matter appears to be constructed from vibrating nothing. The upper rungs of the particle-physics faculties at Princeton, Stanford, and elsewhere in the academy are today heavy with advocates of “string theory,” a proposed explanation for the existence of the universe.

I just invented the part about the hoods. The Middle Ages? No, the current situation in university physics departments. The leading universities are dominated by hooded monks who speak in impenetrable mumbo-jumbo insist on the existence of fantastic mystical forces, yet can produce no evidence of these forces and enforce a rigid guild structure of beliefs in order to maintain their positions and status.
