X = M-theory
Despite an intriguing web of plausibility arguments and consistency checks that have been amassed since this picture emerged in the “second superstring revolution”, it has remained unclear, and largely unexplored, what any of this really means mathematically – notably what putative M-theory on fluxed and G-structured super-orbifold spacetimes actually predicts, with any certainty, for observable physics – be it in its application to confined hadronic matter (holographic QCD), or to quantum-supreme solid states (holographic CMT), not to speak of the more traditional but less tangible application to quantum gravity.
If history is a good guide, then we should expect that anything as profound and far-reaching as a fully satisfactory formulation of M-theory is surely going to lead to new and novel mathematics. (Greg Moore, Physical Mathematics and the Future, p. 44))
