Has there been a moment, where the diameter/radius of the universe in Planck lenghts matched the mass in Planck masses (dark + baryonic)?

    $\begingroup$ Based on current observations, there is no radius or diameter of the entire universe, since it seems to be infinite. However, if we constrain this question to the observable universe, we could probably answer it. $\endgroup$ Sep 14, 2022 at 18:11

  • $\begingroup$ It seems that the moment is ahead of us. I want to see, if the Sciama's formula for G works out exactly at some point in time G = c^2/sum(all masses in universe)/radius o universe) = mass/radius of universe = 1/1. It should hold true a few billion years away from now, I just want a confirmation. $\endgroup$ Sep 15, 2022 at 17:40
