OK, first of all, Ken, you have to recognize that what you're asking for are the meanings of those terms AS USED IN PHYSICS, and not as you've made them up to mean. Because what YOU think those terms mean is completely different than what they really mean. As has been told to you many, many times before, it is going to be useless for you to understand relativity if you don't even know the meanings of the words used in describing it, and a dictionary of everyday language usage is of no help with that. You MUST find the definitions of the terms AS USED IN PHYSICS. If you recognize this, then I'd be happy to tell you what an inertial reference frame means and what an absolute rest frame means. And I'll even be able to give you some web references so you can look them up later when you forget. > > Ken Seto > > > > > Stop making things up, Ken! > > > > However, inspite of these qualifications > > > Einstein proceeded to use the exclusive properties of the absolute > > > rest frame to derive the SR math.

An Observer is at rest with respect to herself. Speed of light appears isotropic TO ALL observer, including the observer's frame. All clocks moving WRT the OBSERVER'S frame show time dilation as predicted by special and general relativity. All rods moving with respect to the OBSERVER's frame would be foreshortened in the direction of radial motion as predicted by special and general relativity. Relativity makes NO use of special frames, as all frames are relative. Ever wonder why it's call "relativity"? Seto--You really need to sit down and learn special relativity. There has never been an observation that contracts a prediction of special relativity. It remains a very fruitful theory and you should take the time to learn it, Seto. What is the experimental basis of special relativity? http://math.ucr.edu/home/baez/physics/Relativity/SR/experiments.html How do you add velocities in special relativity? http://math.ucr.edu/home/baez/physics/Relativity/SR/velocity.html Can special relativity handle acceleration? http://math.ucr.edu/home/baez/physics/Relativity/SR/acceleration.html
