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

  • Are you familiar with standard computations in cosmology involving e.g. the Friedmann equations? – Danu Nov 20 '14 at 20:52
  • 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. – Chris Laforet Nov 20 '14 at 21:02

    many books on cosmology and/or GR (e.g. Carroll's book on GR) discuss these matters. Have a look around (outside Wikipedia ;) ). – Danu Nov 20 '14 at 21:20
  • When you ask for the expansion rate, are you asking for the Hubble constant? –  Nov 20 '14 at 22:19
  • @BenCrowell: yes, the Hubble constant – Chris Laforet Nov 20 '14 at 23:20
