This assume a car, which looks like a Corvette which I assume is fairly
fast. So, for 80mi/hr that is 128km/hr or .036km/sec. The v/c =
1.2×10^{-7}. The Lorentz gamma factor γ = 1/√(1 - (v/c)^2) for a small v/c
is approximately by binomial theorem
γ ≃ 1 + ½(v/c)^2 = 1 + 7.0×10^{-15}.
The time difference is given by the ½(v/c)^2 = 7.0×10^{-15}.. A year is
3.15×10^7sec and Andromeda is 2.5×10^6 light years which means t =
7.9×10^{13}sec is the time it takes light to reach us from there. I then
get .55sec as the time difference for t’ = t/γ.
