Theory Update 112

For many years, kneemo has tried to get me interested in the classical geometry much beloved by traditional M theorists. An early push on this front included Szabo's 2002 paper on tachyons and K-homology. So when number 26 made a few remarks at the viXra log neutrino post, sounding for all the world like a numerology robot, it nonetheless caught my attention, because robots don't usually know that $120$ is a very, very interesting number.

Recall that, back in 2006, we were very excited that the orbifold Euler characteristic of the moduli space $M_{2,0}$ of the genus $2$ Riemann surface with no punctures was $-1/120 = 2 \zeta(-7)$, in terms of a zeta value. This is because $M_{2,0}$ belongs to the triplet $(M_{0,6}, M_{1,3}, M_{2,0})$ of moduli spaces of twistor dimension. We already knew that the number of generations for mass quantum number came from the $-6$ for the moduli $M_{0,6}$, by halving. Similarly, we halve the $-1/120$ to get the $\zeta (-7)$ much beloved by number 26.

Not being an expert in classical geometry, I am still rather unsure about some of the things that number 26 said, but I am quite certain that some of the things that number 26 said are in fact closely related to mass generation in quantum gravity. Long live tachyonic neutrinos.
