### Tachyon Theory Update

Other categorical mathematicians will also be busy studying neutrino physics. In August, Baez et al wrote about $2$-groups and teleparallel classical gravity. Unsurprisingly, the late 2011 neutrino theory arXiv onslaught contains a consideration of teleparallel ideas, linking torsion to superluminal neutrinos. There is also a 2007 model of a teleparallel neutrino. This is a long way from deriving GR via teleparallelism, but we should appreciate the growing web of support for tachyons arising in Fourier duality.
