The metric of a 3-D positively curved space is dr2+ Sk(r)2(dθ2+sin2θdΦ2).
Now if this space expands with a scale factor a(t) from r to r'.
Whether the change in the radial component be a(t)dr and angular component be Sk(r')dθ and Sk(r')sinθdΦ since the change due to expansion is already incorporated in Sk(r')??
