My thoughts "Emergent physics: Fermi point scenario G.E. Volovik" http://arxiv.org/abs/0801.0724 Emergent physics: Fermi point scenario G.E. Volovik What if Volovik is correct that the true TOE is some sort of Fermi point scenario? 1 string theory is dead, and SM particles are not strings in 11 D space. page 4 "In the fermi point scenario spacetime is naturally 4 dimensional...this is a property of fermi point topology which is distinct from string theory does not require higher dimensional spacetime" 2 lqg, cdt and other BI approaches are dead "one cannot obtain qg from full quantization of Einstein's equation" 3 GUT are limited, GUT at best are low energy effective theories, and Volovik's idea is that above GUT there is anti-GUT, and scale goes beyond planck scale, Anti-GUT is based on the idea that symmetry is emergent 4 - prediction no DSR at planck scale, but energy scale does go beyond planck scale where there is lorentz violation 5 Smolin arguments about BI and geometry encoding spacetime as the central lesson of GR are physically incorrect Wen and Levin pattern their TOE after boson string net condensation, Volovik after fermionic topology. Going forward, condense matter physics models represents the model by which fundamental physics can be explained (if Volovik is correct) If Volovik is correct, it seems unlikely the current investment in string theory and LQG will pay off, in developing a physically correct TOE; at best some form of spin foam could be useful if it offers a suitable spacetime atom, whose collective properties can be described by a fermi point or string net.
