Hi, I am a string theorist and a publicist.

comment Poisson structure on moduli space of CFTs
The extra structures exist in supersymmetric CFTs and they're consequences of supersymmetry (which makes these moduli spaces complex, hyper Kahler etc.). If you take the most generic (bosonic) CFTs, I think that the Zamoldochikov metric is the only structure of this type.

comment The quantum state can be interpreted statistically, again
I think that these discussions don't really belong to a physics forum. All these papers – whether they have "can" or "cannot" in the title – implicitly and sometimes explicitly assume that there is an objective and in this sense classical "model" that underlies the probabilistic predictions. The absence of such a model can't be "proved quite rigorously" which is why additional research about such proofs is a hobby for mathematical nitpickers but the physics observations surely do imply, in the physics sense, that the positivist/Copenhagen/probabilistic/Born interpretation is the only one.

comment About the decay of Higgs into 2 Z bosons
It's very strange how you're canceling mistakes against correct factors. The SM Lagrangian at two places is either equivalent up to a field redefinition or one of the places are wrong. Moreover, the decay width is proportional to the squared amplitude, so if the amplitude is doubled by a factor of 2 error at the beginning, then the probabilities and decay rates will be quadrupled ie changed by a factor of 4 which doesn't cancel against 2.

comment Redshifting of Light and the expansion of the universe
Dear @Anixx, it is a law of physics but it only holds, via Noether's theorem, for systems whose laws of physics explicitly obey the time-translational symmetry. Cosmology doesn't belong to this list. Lawrence's confused presentation of cosmology as "photons in the Pound-Rebka experiment" i.e. in Earth's gravity field makes no sense because of the cosmological principle which guarantees that the photon energy can't depend on the location. At any rate, its energy is just getting lost in cosmology and there's no "non-vacuous" way to account for it. The law breaks down, much like the symmetry.
