Cosmic History and Matter Generation in Non-Equilibrium Dynamics: Consistency with Standard Cosmology, and the Sufficiently Large D at Primordial Galaxy Formation
Abstract
We show that in Non-Equilibrium Dynamics (NED), if matter generation occurs after
the formation of Planck particles, at D ≳
√
Dnow, the theory is consistent with standard
cosmology and observations. The key time scales are:
t(MH) ≈ 2.2×10−43 s (hydrogen mass), t(
√
Dnow) ≈ 3.8×10−29 s, t(Mp) ≈ 4.7×10−29 s.
These correspond to the Planck era and the post-inflation era, respectively, and matter
generation after t(Mp) is well before Big Bang nucleosynthesis (BBN, ∼ 1 s) and the cosmic
microwave background (CMB, ∼ 3.8 × 105 years). Thus NED does not interfere with the
successful predictions of standard cosmology.
We also estimate the coupling parameter D at primordial galaxy formation (t ∼ 7 × 108
years):
Dgal ≈ 6.8 × 10119
.
This is about 2% of Dnow, but is sufficiently large to allow complex structure formation.
Therefore, the environment for galaxy formation was already in place at that time.
