maybe you are right but you should ask a spcialized scientist..and take into your consideration: In Einstein's universe, time and distance may stretch like rubber, but the speed of light remains immutable…you are confusing yourself by thinking of the rate of expansion as a speed. It's not. It's a percentage per unit time, approximately H = 0.007% per million years. What you describe here is the case of a constant Hubble parameter, which is equivalent to exponential acceleration.In a non-accelerating universe the Hubble parameter will be proportional to 1/t. Distance d = v*t, v=const -> H = d/v ~ 1/t. Observations and measurements in 1998 surprised most scientists, including those doing the work, finding the expansion of the universe is currently accelerating , although the Hubble factor is still decreasing over time. The Hubble "constant" is not really constant varying with time according to your choice of cosmological model.
