Do physicists know what the expansion rate of the Universe was at the beginning of the matter dominated era?

$\begingroup$ Are you familiar with standard computations in cosmology involving e.g. the Friedmann equations? $\endgroup$– DanuNov 20, 2014 at 20:52

$\begingroup$ I am familiar with the Friedman equations, but not calculating with them. I was just curious if there was a consensus regarding what the expansion rate was at the radiation/matter transition and matter/dark energy transition. $\endgroup$– Chris LaforetNov 20, 2014 at 21:02

1$\begingroup$ many books on cosmology and/or GR (e.g. Carroll's book on GR) discuss these matters. Have a look around (outside Wikipedia ;) ). $\endgroup$– DanuNov 20, 2014 at 21:20

$\begingroup$ When you ask for the expansion rate, are you asking for the Hubble constant? $\endgroup$– user4552Nov 20, 2014 at 22:19

$\begingroup$ @BenCrowell: yes, the Hubble constant $\endgroup$– Chris LaforetNov 20, 2014 at 23:20
