It's imaginary, to be generous, and as under-defined as to be un-physical. The geodesy, is always instantaneous, everywhere. The sky survey, has that instead of Hubble's "expanding universe", it's not. Neither the Big Bang nor Steady State hypothesis is falsifiable, and science without falsifiable is not science. The real wave collapse, gives Heisenberg certainty. The Higgs boson, is a doublet. These days there's also Little Higgs, and for making "Medium Higgs: the atom". String theory, is just whatever is "continuum mechanics", as just a grainier-grain than the atomic scale - it is what it is, and can fit in 3 + 1/2, and in 1. Supersymmetry, is alive as ever, and, not merely high-energy nor merely low-energy nor merely meso-scale, yet each. The "ultraviolet catastrophe" as about blackbody radiation and "ultraviolet cutoff" as about finite-element-analysis, are two different things, and QED does not get a pass to say that's anything other than finite-element-analysis. The "ultraviolet catastrophe" then for the "infrared catastrophe" to make for purple/indigo/violet, the other way, is that a great opportunity to fit with the success of spectroscopy and electron physics, is neutrino/muon/hadron physics, because beta decay is a continuous process, AND because electron discreteness stops working in larger atoms, why "infrared catasrophe" is a great idea because there's another crisis in physics since the last one, "ultraviolet catastrophe". Statistics, is not necessarily Bayesian. I enjoyed listening this 4-hour Carroll lecture "It's not a crisis ..." yet don't all agree, and the 15 or 20 some theories mentioned none of them get into _all_ the configurations and energies of experiment. I feel asleep for about an hour, it's a good survey, of the physics ward. https://m.youtube.com/watch?v=MTM-8memDHs Then, the "infrared catastrophe", is about low energy and high energy, also with regards to "not-unification", and symmetry-flex not symmetry-breaking, and running constants, and more and better mathematics of convergence. One of physics' big problems today is about momentum, and the angular and linear and rotational and spiral, because as Einstein puts it "the physics is an _inertial_ system", and, the classical definition of "resistance to motive force the impetus the motion", is as of the inertial, and besides, active force is evident in footballs, or for example rifling, and merely the gyroscopic, or nutation of a top, mechanics. Then, physics needs a thoroughly holistic account, and much of it is fixing about 0/1/infinity, and what mathematics _owes_ physics in probability theory and statistics, convergence, and even models of mechanics, and motion. Now see here: 0 meters per second, is infinity seconds per meter.
