Under those conditions, the density in the Friedmann equation can be taken as that associated with the radiation field and related to the ratio of the temperature at a given time and the current temperature of the cosmic background radiation.

The new scheme is applied to the quantisation of a Friedmann Universe with a massive scalar field whose dynamical behaviour is investigated numerically.

Calculation of expansion time.

Non-singular inflation with vacuum decay - Carneiro, Saulo J.

Difficulties with inflationary cosmology - Penrose, R.

Note that this calculation includes only the photons and neutrinos, and does not apply to the times before the annihilation of most of the electrons and positrons.
