MacM:
No. Clock rates are different in different frames. That is what time dilation is all about.
False. d = vt requires tick rate remain unchanged or you get different accumulated times on the clock. What you call time dilation is non-existant and is an artifact of claiming the also non-existant length contraction of space.
Excuse me?
Where has it been shown experimentally that time dilation does not occur? In fact, experiments show precisely the opposite thing - time dilation is real and measureable.

lt would appear that the introduction of the Doppler shift into our calculation results in disagreement of Michelson's experiment with the constant light velocity hypothesis and the "elastic reflection theory" gives the correct results.
From the previous paragraphs we cannot help but conclude the fact that the relativistic point of view (constancy of the speed of light and that of radio waves, x and g rays relative to all and every reference system no matter what its state of motion) is simply untenable.
Basically, time and space are abstracts, not related to any material matter.
Similarly, time is running out at a fixed rate in a single direction (forward) without relation to any material matter and it cannot be influenced by the existence of matter in any state of motion.
On a 74 ft. high tower they found a Doppler difference of (5.13 ± 0.51) x 10-15 between up and down direction which compares well with the theoretical 4.92 x 10-15.
Consequently to what was said in the previous paragraph (6), if a gravitational field can cause a Doppler shift on an electromagnetic energy quantum travelling with velocity of light (c) then its own velocity of propagation
(gravitational) must be in excess of c (by at least a factor of 10 or probably more than 100).
To conclude with a quotation of Dr. Walther Rauschenberger[2]:
"The acceptance of the TR. will go down in history
as one of the most remarkable errors of the human mind."

But we know that , and since the Pound- Snider experiment tells us that we know that . Therefore
we have to conclude that our answer using Minkowski geometry is wrong!

It is seldom realized that `seeing' is a physical process of image formation in which the image is fundamentally different from the object.
One notable exception is Bridgman in the closing sentence of his contribution to the Einstein celebration volume [15]: "That in his conviction of the possibility of getting away from any special coordinate system, in his conviction of the fruitfulness of so doing, and in his treatment of the event as something primitive and unanalyzed, he (i.e., Einstein) has carried into general RT precisely that uncritical, pre-Einsteinian point of view which he has so convincingly shown us, in his special theory, conceals the possibility of disaster".
Bridgman evidently is worried about Einstein's preoccupation with physics as a description of an objective reality, i.e., a description in which the process of observation is completely left out of consideration. Presumably Bridgman was
aware of the danger that this neglect of the observation process could easily shift the meaning of a tensor component from `a property as seen by an observer in his coordinate frame', to `a property the object has relative to the observer in his coordinate frame'.
Such a shift would imply a fundamental change in the philosophical significance of the theory. The former view could be reconciled with the existence of an objective, observer-independent reality, the process of observation being responsible for the different results obtained by observers in different reference frames (e.g., length measurements by observers having different relative velocities). On the latter view an objective reality would be impossible.
In a realist interpretation of RT Fig. 1 could in principle be taken in the sense of Whitehead, each reference frame providing its own relative reality. Yet, from a physicists point of view this is not very attractive. The reason for this is the acausal behaviour of R's clock in the description of Fig. 1b).
Evidently, if tR would be the clock rate as it `really' is relative to the reference frame Sigma co-moving rigidly with T , then T 's acceleration r (t) r (t) r t or t 2m.
Figure 2: Radial coordinate as measured by a static and a co-moving observer. would have a strange non-local rate enhancing effect on R's clock. Such an effect would be contrary to the very spirit of RT, no local cause being available for an explanation of this effect. For this reason it would seem appropriate to try to find an alternative solution.
Indeed, an empiricist interpretation offers better perspectives in this respect, because in this interpretation it is possible to accommodate the causal aspect of the correlation between T 's acceleration and the enhancement of R's clock rate by reference to the measurement process.
Maybe we should take seriously the often-used phraseology
`T is seeing a certain rate of R's clock', in the sense that the process of `seeing' is a physical process of measurement liable to distort the input signal. The formalism of RT might describe just the output of the measurement process, i.e., the readings of the measuring apparata.
Reciprocity can then be understood on the basis that, if both R and T are inertial, then their measurement procedures are equivalent, and data will be distorted in the same way. However, acceleration of T could influence his measurement procedure, thus causing him to `see' an enhanced clock rate.
The idea that an object never crosses the Schwarzschild radius is a consequence of a realist interpretation of the theory, neglecting the difference between
`what happens' and `what is seen'.
If R would entertain a realist interpretation of RT, this would be a rather alarming observation, since the interval (PA; PB) finally marked off by T did not have a complete overlap with R's object at any time of R's description. R's description of T 's measurement procedure
would not be distinguishable from the description of the acts of a fraudulent surveyor who, on measuring a piece of land, allows his measuring rod to slip while walking from A to B.
On the basis of a realist interpretation of his description R would have to distrust T 's measurement result. Also here an empiricist interpretation could do justice to T 's fair intentions, however: what R sees need not be the same as what is really happening.
Although Lorentz contraction (and time dilation [22]) are consistent with a dynamic description of the behaviour of length and time measuring instruments under slow trans port, it is also
clear that this is only true in an unphysical `ideal' limit.
It is clear both from the calculations in sect. 4 and from the abovementioned discussion that
there exist many observation procedures not yielding outcomes that correspond with an objective description of the object.
It seems that both in QM and in RT the situation is, indeed, comparable to a non-flat mirror. As far as the theories remain empirically adequate also in this situation
we will have to allow for a correction of this distortion in order to obtain a true picture of reality.
It seems to me that an empiricist interpretation of both theories can provide a consistent picture in which both the quantum mechanical observable and space-time metric are just kinematical prescriptions defining measurement procedures valid within the domains of application of quantum mechanics and RT, respectively.
To what extent observable and metric can be considered as properties of an underlying reality does not seem to be a question that can be answered on the level of either QM or RT.
However, as we have seen above, paradoxes may arise if such a realist interpretation is applied too easily.

The trouble is that A and B above give a different answer that B and R above.
This means that Special Relativity (and by extension General Relativity) have failed.
This equation shows that when V is almost as large as C, and has the same direction, then the force transferable (henceforth known as transferability) is very small and the acceleration achievable becomes very small.
Einstein contended that the reason for this factor in the equation was due to the objects increasing mass, and hence there is a reduced acceleration given a constant force.
What I believe to be really happening is that as we approach the speed of light relative to the fields around us, the forward propagation (in the same direction as our velocity) of the field is reduced in speed relative to ourselves.
The result is that the forward force is reduced to zero as we approach the speed of light because the motion of the two fields, relative to one another, drops to zero.
((((BINGO - The UniKEF view where mass does not increase but energy transfer efficiency decreases.))))

Although their use is analogue in character, there is no doubt that infinitesimal light-clocks imply that gravitational
alterations attributed to "time-dilation" are actually alterations in behavior associated with an electromagnetic interaction with the gravitational field.

As with time dilation, the situation
must be symmetrical. If objects, such as the atmosphere, that are at rest relative to the Earth appear contracted to the muon, then objects moving with the muon must appear shortened by the same factor when viewed from the Earth.
Consider for example the size of the muon itself. Muons are very tiny particles and have virtually no extent, but let us for the sake of illustration assume that as measured in the muon's frame of reference, it has a width of one centimeter.
Length contraction tells us that the size of a muon moving at 0.99c will appear contracted to one seventh of its true size (or just over a millimeter) when viewed by an Earthbound observer.
Thus, as expected, lengths of objects attached to the muon appear contracted as seen from Earth, whereas lengths of objects moving with the Earth appear contracted as measured in the muon's frame.

[post=710255]Another Experiment Here[/post]
Hartwig Thim
Experimental refutation of Relativistic Time Dilation
An experiment is described showing that a 36 GHz microwave signal received by rotating antennas
is not exhibiting the frequency shift ("transverse Doppler effect") predicted by the relativistic Doppler formula.
From the observed absence of the transverse Doppler shift
it is speculated that either the time dilation predicted by the standard theory of special relativity does not exist in reality or, if it does, is a phenomenon which does not depend on relative velocities but may be a function of absolute velocities in the fundamental frame of the isotropic microwave background radiation.
This second possible conclusion agrees with some theories for a computational background to the universe.

This recipocal (symmetrical) reciprocity insures NO NET SYSTEMIC MEASUREABLE TIME DILATION.
If you continue to argue the "Reality" of Relativity vs the "Perceptions" of Relativity you sir are a fool, not I, nor the many that disagree with you.
