But AFAIKT it does not really purports that. It purports that physical processes will behave in the same manner regardless of one's linear velocity. By extension, this means light's speed also appears to measure the same speed. It actually says nothing about absolutes. What it is really saying is, the universe is internally self consistent. The real issue 'at the time' of both LET and SR development was the very basic structure, and nature, of material systems since these are necessary to make any such measurements. Even in aether theory there really isn't any actual 'absolutes', just a universal framework. As for time dilation, there never is, nor can there ever be, an actual paradox. Only limitations on understanding and modeling actual physical behavior. In the case of inertial motion one should alway evaluate the problem from the sum v = 0 frame of reference. In the case of twins one or both must, by definition, undergo accelerations to change their speeds. This make the problem, also, by definition, a basic non-inertial system problem. SR 'traditionally' and originally was conceived to deal with the inertial state only. When you take your symmetrical twins problem and evaluate it from the point of origin frame you'll find that the elapsed times are, also, symmetrical. That's the proper solution. Regards, Paul Stowe

So how would you interpret the following? "the phenomena of electrodynamics as well as of mechanics possess no properties corresponding to the idea of absolute rest" Einstein, "Electrodynamics of Moving Bodies" Also, can you show anything from Einstein's description of the principle of relativity which supports the idea of the existence of absolutes?

Is this throughout all of Einstein's writings or are you asking within the 1905 paper? Paul Stowe

From the 1905 paper, as that is where the first postulate of SR originated. |
