2/ Grok continued to disagree and forced me to counter-argue quite a bit, until I finally found a connection with the KL representation.

non-perturbative extension of QCD, and not simply a reformulation. I erred in attempting a perfect fit with YM because YM is incomplete in the IR regime and therefore cannot describe confinement. I can now finish the paper.

"High-precision statistical Landau gauge lattice gluon propagator computation vs. the Gribov–Zwanziger approach," Annals of Physics 397 (2018) 351–364, for improved forms of the propagator.

See "The gluon propagator," Physics Reports 315 (1999) 273–284, for a summary of some of the most studied ideas and speculations about the infrared behavior of the gluon propagator, and...

A science is based on the application of the scientific method. Cosmology cannot perform repeatable experiments on its object of study (the universe) and relies solely on observational data and interpretations.

Cosmology is, at best, a half-science.

There is no central singularity.

The Coulomb gauge is as physical as the Lorenz gauge.

Note: the correct term is Lorenz, not Lorentz.

It can be shown that the Bethe-Salpeter equation is incompatible with both quantum mechanics and special relativity. This is the reason why it predicts several unphysical phenomena

Both definitions are identical and one can be derived from the other.

Ordinary Boltzmann and Gibbs entropies can deal with nonextensive systems.

Space and time are fundamentally different at the quantum level. Poincaré-invariant quantum equations are fully compatible with observations.

This is as incorrect as pretending that temperature is the reading of a thermometer. This is not even a correct operational definition.

The reason is that classical electrodynamics describe interactions locally.

Heat capacities are positive: e.g. (\partial E / \partial T)_V > 0. What has been measured are not heat capacities, but total energy-to-temperature ratios.

Superluminal expansion of the Universe is happening today, some galaxies have recession speeds greater than c.
