Quote by Michael Mozina
Well, let's look at the assumptions they begin with.
1. INTRODUCTION
Ordinary matter constitutes about 4% of the closure density of the Universe,

That is only true according to LambdaCDM theory. If you don't subscribe to LambdaCDM theory, (for instance you're a MOND theorist) this statement is false.

Incorrect.
The conclusion that ordinary matter constitutes about 4% of the closure density of the Universe is derived from the standard BBN processes taking place in a universe that expands according to GR when it is dominated by radiation.
In that case [itex]p = \frac{1}{3} \rho c^2[/itex] and the scale factor is given by R(t) [itex]\propto t^\frac{1}{2}[/itex].
This sets the limit on the time for nucleosynthesis to continue.
Dark Matter and Dark Energy have nothing to do with it.
