Does the George-Johansson theory of the universe expansion explain where the anti-matter went?

George and Johansson [1] combined ideas from turbulence with Einstein’s field equations to develop a new theory of universe expansion. It assumed the universe to be homogeneous and isotropic at present, then worked backwards in time to when quantum mechanics ruled. Both gravitational time and space expanded together and were described by a single time-dependent length scale, say δ(t). Atomic clock time, τ, the proper time was related to the gravitational time, t, by t/t_o = exp(τ) where t_o (or τ = 0) is the time of the Big Bang. δ(t) varied linearly with t, but exponentially with τ. The energy density varied as 1/t² and extrapolated smoothly from current mass densities 120 orders of magnitude to the QFT estimate, the so-called “Worst prediction in the history of physics.” There was no dark matter, no dark energy, no critical mass, no inflation nor was new physics needed. The Hubble parameter varied as 1/t; and the theory predicted H/H_o= 1+z. From data, H_o = 63.6, corresponding to a universe that is 15.4 billion years old. The supernovae data was well-described using only H_o and M = 18.5, the Chandrasekar limit. Since our equations are valid for antimatter, we use Feynman’s proposal that the antimatter at creation propagated backwards in time and our solution to explain where it went. We also show how our theory has anticipated recent JWST observations.
