anyone to understand conclusively why
Throughout history there have been a number of correct arguments to show the flawed nature of Einstein's relativity1, notably ref.2,3, but they have always been partial, leaving the impression that Einstein's relativity can be salvaged somehow and be used for something in physics.
The original argument chosen to be presented here
cuts into the heart of Einstein's ``theory'' of relativity, definitively
disproving it in its own terms, directly within the 1905 paper itself.
It is a final, unequivocal argument. Here goes ...
Einstein has applied that one and only way on pages
917 and 918 of his paper:
In doing so, the author of that 1905 paper most definitely
should have ended his effort to put forth a new theory right here, and
should have refrained from publishing this trivial result, which constitutes
no discovery at all. Any other way of representing the law will not leave
the shown law unaffected, and that will contradict the quoted first postulate.
In other words, Einstein's relativity derives the
evidently physically impossible conclusion that one and the same body
in one and the same system, system K,
is supposed to obey two different laws of motion at the same time; namely
That is to say, in effect, Einstein's relativity
ends up deriving the impossible equality 1 = 2, which is obvious nonsense
and which clearly can never find any experimental confirmation. Therefore,
Einstein's relativity is conclusively seen to be invalid, prior to any
experimental testing. Thus, any claim for experimental confirmation
of Einstein's relativity must necessarily be rejected outright.
The mandatory rejection of Einstein's relativity must lead to the outright rejection of any senselessness said to follow from it, such as time-dilation, length-contraction, relativity of simultaneity and spacetime as well as an outright rejection of any of its progeny, such as, general relativity, cosmology, string theories, black holes, particle physics theories and anything else in any way connected with Einstein's relativity. As a detail, it should be clear that not only is the mass-energy relation E = mc2 not a discovery of Einstein's relativity but Einstein's relativity cannot even derive it. Mass-energy relationship E = mc2 is trivially present in classical physics, e.g. Ampere's law is one expression of that relationship; Newton's second law, corrected to reflect motion, also expresses mass-energy relation. Mass-energy relation in classical physics is discussed elsewhere.Therefore, Einstein's relativity must be removed from physics in its entirety, the way weed is removed from a wheat field without replacement.
