Physicists are quite used to the idea of unifying laws of nature. Ever since the ancient Greeks they have worked with the unreasonable effectiveness of mathematics (to quote Weyl). Most physicists are therefore convinced that a theory of Quantum Gravity (a loose term for something that unifies QFT and GR) exists. Moreover, this theory must be predictive. The idea of a Landscape is outrageous and, since we already have better ideas anyway, one wonders why people persist with such investigations.
A theory of Quantum Gravity will say some radical things. Many physicists are now happy with the idea that spacetime disappears and is in some sense generated by the matter degrees of freedom. Einstein could not, in the end, incorporate a Machian inertia into GR, but we expect Quantum Gravity to be able to achieve this. After all, it only fell over with Einstein's commitment to a classical differential geometry. However, to believe that any old background independent description of quantum covariance which yields roughly the standard cosmology would be radical enough is, perhaps, to underestimate the meaning of the word radical.
For starters, some of us are now fully convinced that Quantum Gravity will do for biology what QM did for chemistry. Of course, this is an arrogant physicist's point of view. A biologist might say that the unified theory of biology happens to provide Quantum Gravity as well. Whatever. It's the same theory.
A little while back we were talking about the number of generations in the Standard Model. It was pointed out that this follows from the orbifold Euler characteristic of the moduli of the six punctured sphere. Actually, the higher n-operads of Batanin highlight the fact that something special happens when one considers the statistics on six objects. Tamarkin showed that for n > 1 the polytopes that are usually considered cannot stabilise moduli. But Batanin's can! The simplest Tamarkin example is for six points as branches of a two level nine edged tree. Since in this setting 2-operads are used to study points in the real plane, this enters into the correct combinatorics for the six punctured sphere. Look out for a paper on this soon!
