Sorry, no etymologies found.
Is a well established non-perturbative approach to solving the quantum chromodynamics theory of quarks and gluons.
QCD tells you explicitly how to evolve these non perturbative functions, but that has to be done with an approximation.
A large body with that sort of mass would have gravitational perturbative effects on planetary orbits or motion.
If as claimed Nibiru is coming from Orion it would be bearing down close to Saturn, with clear perturbative influences, and those would be correlated with perturbations on Jupiter.
Such techniques have been used in other perturbative problems.
If this works then the perturbative Killing fields are on comoving frames, and the difference between them from region to region might then lead to inequivalent vacua from which some of these types of analyses might be performed.
But still we do need a cutoff (to be differentiated from the scale at which the theory is defined) to handle UV divergences, for example in perturbative QCD.
Anomalous symmetries (must be global) are exact classically and at the perturbative quantum level.
Thanks to the non-perturbative, background independent methods, unlike in other approaches the quantum evolution is deterministic across the deep Planck regime.
Who is to say whether a universe described by the non-perturbative completion of superstring theory is likelier or less likely than, for example, a universe described by a Rule 110 cellular automaton?
