::::::: Clement, you're not responding to my points, and you've resorted again to a petulant mode. Do yourself a favor: open your mind and think more for yourself, rather than simply repeating what someone else said. Suit yourself, but I'm moving on to others. Thanks and Godspeed.--[[User:Aschlafly|Andy Schlafly]] 18:23, 21 April 2009 (EDT)

ClementB, doesn't "a certain velocity V" imply that Einstein is saying that the speed does not change during the scope of the problem?
For instance, if I say "If a certain man V is President for two full terms, V may not be elected to a third term" or "There is a certain function f such that if a car is traveling at a certain velocity V that is less than the escape velocity, then it will fall to Earth in less than time f(V)", then the variables are not changing over the scope of the problem, no? And since some problems take place over very long periods of time, the velocity is assumed not to change over that whole period, no? And doesn't that imply that the speed of light is constant, no matter how far your twin travels? [[User:BHarlan|BHarlan]] 18:26, 21 April 2009 (EDT)
