So are you saying that the same laws of electrodynamics and optics are not valid for an absolute frame? I don't think so.

I'm sorry, Ken, but what you wrote as the exclusive properties of an absolute frame are what you made up out of your own head. This is not what an absolute frame means in physics. It may well mean what you say it means in your own head, but that doesn't have anything to do with physics. Just because you assert it doesn't make it so. The properties of an absolute frame are documented and it's what I told you already. If you need proof of what I've said, I'd be happy to point you to some references where you can read the documentation. > The fact that every inertial observer adopts them as the > properties of his frame does not invalidate them to be the properties > of an absolute frame. What invalidates them as properties of the absolute frame is that this term is already used in physics to mean something completely different than what you say it means. Just because you assert them to be the properties of the absolute frame does not make it so. > > > > > What an absolute frame in physics is, is documented in black and white > > in several books I can recommend to you. > > All the book written so far gave the wrong interpretation for the > properties of an absolute frame. Ken, Ken, Ken. This is the problem, you see. You use terms that are already in use in physics, and which have very different meanings. You do not understand the meanings of the terms, and so you make something up. Then when it is pointed out that the terms do not mean what you think they mean, you insist that all the books are wrong, and that what you've made up in your head is the right thing. All you're doing is denying reality, and substituting your own fantasy. This is called psychosis. For fifteen years, people have been begging you to learn the meaning of words as used in physics so that you stand a chance of 1) understanding the physics and 2) conversing coherently with physicists. You have steadfastly refused to do this, preferring to make things up when you don't understand them. To insist on this foolish path for fifteen years is just ludicrous. > > Ken Seto > > > This removes the matter > > completely from argument. If you disbelieve what I tell you, then look > > it up.
