I was just reading about how the redshift-relation for angular diameter distance is calculated, and the example in my textbook used a matter-dominated universe to calculate the formula. It seems to rely heavily on the relationships between t, a(t) and H(t), which are different in radiation dominated universe. Does the final result end up the same regardless of the content of the universe? I have tried to work through with different values but it's beyond my abilities!
