It can't be observational *and* defined. And if it's definitional, then how could observations contradict it? There are numerous problems with SR, in addition to the quite fundamental problems also inherent in other contemporary scientific theories. One of the largest is the exceptional way in which the principle of "the relativity of simultaneity" is applied. It claims to be universal, yet it isn't applied to the synchronization of clocks, a fundamental measurement preparation upon which all observational data in SR is based. In SR, each valid observational frame is permitted to assume itself at rest and to conclude that its observations are in some bizarre quasi-objective sense correct: each observer, in different frames, can claim that his own observations are genuine, no matter how they appear to be contradicted by those of other frames. Thus, given observers in two frames in relative motion (A and B), each can assert that his own frame is at rest; and combined, these constitute an assertion that both A and B are at rest even though there is relative motion between them. Each is deemed to be "right" even though both being "right" is paradoxical. Yet, with respect to the synchronization of clocks, frame A does not claim that his own observations are correct with respect to frame B. For example, if frame A assumes that frame B is "moving" then he has certain assumptions about the distance light travels between B's clocks during motion by B (hence during motion by those clocks); and these are different from the assumptions that B has about this, since B assumes that B is at rest (hence his clocks are also at rest). Since the distance that light travels is part of the determination of clock-time in SR clock synchronization procedures, it is clear that if the principle of the relativity of simultaneity were correct *and* applied to all procedures, including that of clock synchronization, frame A would have to assume that B was mis-synchronizing his clocks, since A's observations tell him this is so. Of course, A would have to assume this about all other frames that are "moving". (Note that A's observations "tell him this" only within the framework of interpretation adapted by A, in which A is "at rest" and B is "moving".) All the "dilations" of SR stem from the failure to apply the principle of the relativity of simultaneity to ALL processes *including* the synchronization of clocks within a frame. If it IS universally applied there is no longer any mathematical basis for them and they disappear from SR formulae results. Of course, even more fundamentally, the concepts of "at rest" and "at motion", much less the transition between the two, as well as those of "location in space" and "temporal coordinates", are all seen, upon rational scrutiny, to be something other than what they purport to be; and as what they purport to be, they are hopelessly inconsistent, vague, and ill-defined.

For the droplet to pass through with negligible deviation, the mass of the smoke particles has to be very much smaller than that of the drop. In our context, that means m * c^2 << h * f which I think is valid. Note the photons don't absorb matter the way the drops absorb the smoke so the matter particles would be bounced away by the high energy photons. We can get direct experimental results in the lab using X-rays and electrons, hence my use of the Klein-Nishina formula which is applicable. >>.....but the final deviation at any distance is apparently >>> smaller than the resolving power of any telescope. >> >>I expected to find a maximum mass for the particle >>when I did the calculation, the result was billions >>of interactions each causing a deflection of the >>photon with a mean angle of 90 degrees.

A number of people have checked it and so far nobody can find an error. Actually I expected someone to find something as it isn't a widely publicised result but not so far so the challenge is there. >>Personally, I don't think you are capable of >>producing a theory from this speculation because >>you need to know the details of the interaction >>but I'll be happy if you can surprise me. > > George, I think your ability to understand experimental physics is sadly > lacking. ROFL! Henri, the reason I got this result is because I did some research and found the experimentally verified equation which is applicable to the situation. If you want to try using some other experimental formula, you are welcome. George

If you measure the speed of a car with a radar gun, you get some value. Jump on a bike and cycle after the car and you get a lower reading. The reading is valid relative to the gun. The same is unavoidable true of all instruments, the readings apply in the frame of the instrument. > Yet, with respect to the synchronization of clocks, frame A does not > claim that his own observations are correct with respect to frame B. > For example, if frame A assumes that frame B is "moving" then he has > certain assumptions about the distance light travels between B's clocks > during motion by B (hence during motion by those clocks); and these are > different from the assumptions that B has about this, since B assumes > that B is at rest (hence his clocks are also at rest). > > Since the distance that light travels is part of the determination of > clock-time in SR clock synchronization procedures, it is clear that if > the principle of the relativity of simultaneity were correct *and* > applied to all procedures, including that of clock synchronization, > frame A would have to assume that B was mis-synchronizing his clocks, Yes, that is what "the relativity of simultaneity" means.

Time dilation is directly measured in the Ives-Stilwell experiment without any use of simultaneity.

Their meaning remains the same as in Newtonian physics. George
