Reply #213: Ignoring your insulting attack on atheists, I say:

A simplifying assumption is not a falsehood by any stretch. Simplifying assumptions are made in the learning process of nearly every discipline in order to gradually progress students toward true proficiency in the field. Look at the word problems near the back of any physics textbook.

"Assume the speed of sound is constant."
"Assume the speed of light is constant."
"Assume a frictionless surface."
"Assume the bear is wearing a bulletproof vest." (One of my personal favorites from high school.)

We do this in order to let students focus on simple application of the basic laws of physics. As their ability to apply basic concepts grows, we introduce more complexity. I don't understand how you don't already know this.

Your use of Wiki doesn't help your case. Wiki is well-known to have discrepancies, outright falsehoods, and bad oversimplifications. If you want to provide proof of something, pick up or find an online copy of a textbook.

Your attempt to classify light as a paradox is still a failure, because light itself has never been constant, which is the assumption upon which all of your "paradox" claims are predicated.
