WebApr 13, 2024 · Upon substituting into the expression for z, above, this is our result. z = S(t0) + ΔS S(te) − 1. Now consider a short time in which the spacetime does not expand by very much. Under these conditions the scale factor will be essentially constant ( S(t0) ≈ S(te)) and we can simplify the expression above.
