"SRT deals with inertial systems. At the heart of SRT there are two basic principles:
a) The speed of light, c, is constant and it has the same magnitude in any inertial system.
b) All inertial systems are equivalent. There is no preferred “rest reference system”.
Thus, the laws of physics are covariant in all inertial systems. Lorentz transformation is profoundly essential to the SRT for it is compatible with the relativity principle: It maintains the covariance of physical laws...
If, according to the equations above, we have absolute simultaneity of events why does the standard interpretation of SRT argue for relativity of simultaneity?...It turns out that two contradicting conclusions, concerning simultaneity of events in the laboratory reference frame are derived from the same Lorentz equations. So in order to restore consistency, this contradiction should be resolved entirely within the framework of the Lorentz equations.
The solution is fortunately very simple. We must notice that we are talking about two different tests and that is the reason we are arriving at two different results...
In this second test, the detection events will not be simultaneous at either of the inertial systems (the railway car or the laboratory or in any other frame). But the time dilation ratio still holds: (3.10) Δt = γ Δτ. We thus have a complementary interpretation to SRT, which restores “absolute simultaneity” of events, independent of the specific inertial reference system...
The “time dilation” effect is considered by the standard interpretation of SRT to be symmetric...[But] in spite of the length contraction of the railway car in the laboratory frame, we obtain a longer time measured in the laboratory, which is expressed by the time dilation effect. The inevitable conclusion is that “time dilation” effect” is inherently asymmetric.
This is a very important conclusion with four major consequences:
1. There is no “twin paradox” in special relativity theory.
2. We do not need the “relativity of simultaneity” effect to maintain the symmetry of the “time dilation” effect, which does not really exist. This, in turn, supports the “absolute simultaneity” argumentation of the previous section
3. Neither do we need any special mechanism to break the nonexistent symmetry of the time dilation effect in order to explain the nonexistent “twin paradox”(2),(3).
4. Moreover, new theories like the conventionality of simultaneity (CS) thesis(4) should not be physically appropriate any more...
We have shown above that “time dilation” effect is inherently asymmetric. We still have to resolve the issue of how such asymmetric effect could emerge out of the Lorentz symmetric transformation....Thus, we have to separate between two types of “time dilation"...The only physical “time dilation” effect physically measured is between clocks in the “laboratory system” and in any other inertial system. This effect is mathematically and physically asymmetric...
Thus, to sum up, while providing an analysis of the clock “time dilation” asymmetry, the main contribution of our new approach to special relativity theory, is the restoration of clock time “absolute simultaneity”, which seems to represent more accurately our existent physical reality."
