The root of it the so-called anomaly, which makes superstring theories mathematically inconsistent. The only dimension where it may vanish is the "critical" one (10), but that in itself is not enough if the global topology is non-trivial. And it has to be non-trivial to compactify the extra dimensions. Since the physical spacetime is topologically trivial ...

I edited your question (I moved one parenthesis so that your quote was not a misquote), and maybe that answered your question. In case not ... If you had a Dirac spinor $\Psi$ then there is a transformation like $\Psi\mapsto e^{\theta\gamma_{13}/2}\Psi,$ where $\gamma_{13}=\gamma_1\gamma_3$ is a product of gamma matrices (or just the unit xz plane if you ...

Mitchell Porter’s answer is very interesting. However, it is also very divergent from what the movie conveyed and the current state of the SUSY vs. Multiverse debate. He uncovers an interesting paper “A Finely-Predicted Higgs Boson Mass from a Finely-Tuned Weak Scale” published in 2009 or four years before the release of the movie. This paper contradicts ...
