Re Dyer, it seems to me you are arguing about infinity*zero. I don't think I should accept that...
I'm arguing that if v(t) is your speed as a function of t (where t is the time in the reference frame of the galaxy), then the integral from 0 to infinity of: (1 - v^2/c^2)^1/2 dt can be made to converge. This will work if you set v(t) = (1 - exp(-t))c, for example. http://en.wikipedia.org/wiki/Proper_time Sincerely, Adam P. Goucher
