:As to the Bible, why do you avoid it so much? I cite it repeatedly in my history course, but I haven't seen you cite a passage from it yet despite all your commentary about history. Do you ever cite a specific passage from the Bible? I'd like to see just one example.--[[User:Aschlafly|Andy Schlafly]] 19:59, 25 April 2009 (EDT)

::''Whoever digs a pit may fall into it; whoever breaks through a wall may be bitten by a snake. Whoever quarries stones may be injured by them; whoever splits logs may be endangered by them. If the ax is dull and its edge unsharpened, more strength is needed but skill will bring success. '' (Ecclesiastes 10:8-10)

::'' If you don't believe me, then plug in a velocity ''v'' greater than ''c'' and watch what happens to the above equation.'' But, as you said, in the formula for time dilation, ''c'' represents the speed of light. Plug in a velocity greater than 300,000 km/sec for ''c'' and see what happens! Nothing much....

+

::I said above: Your formulation: the ''speed of light can never be increased'' doesn't prevent that a static observer '''A''' and a moving observer '''B''' measure different quantities for the speed of light. It only implicates that these measurements doesn't differ from their own earlier - or later - done measurements.

+

::In fact, that's my biggest rub with your formulation.

+

::The existence of a ''maximum fixed velocity for light'' (though not it's quantity) is a consequence of Einstein's postulates '''if they are stated correctly'''.
