Doesn't compute. A quantitative prediction need
only be empirically falsifiable in principle, not in
current fact or within current capability, but that's
not the point here. More to the point, Giwer
seriously underestimates the scope of current
astrophysical observations.
The laws of physics aren't guaranteed to be globally
invariant, but local invariance can be centered at any
point in time and space. However, physics provides
the necessary global transformations between various
local reference frames.
Under such global transformations, the light emission
and absorption spectrums of the hydrogen atom,
amongst many others, are observed to be invariant
WRT cosmological distance. Near or far, throughout
the observable Universe, the laws of Quantum
Electrodynamics are observed to be locally invariant.
Much the same can be said for the physical laws of
gravitation and of the Standard Model of Particle
Physics.
