Proper distance from the FRW metric

  1. Nov 16, 2015 #1
    1. The problem statement, all variables and given/known data
    Question:

    2. Relevant equations

    Dp=R(t)Dc where R(t) is the scale factor, Dc is the comoving distance

    3. The attempt at a solution

    I must have tried solving this starting 10 different ways now, starting with the fact that distance=integral over velocity dt, trying to integrate the metric itself with dphi=dtheta=0 and I just can't get anywhere at all.
