SR stands for Special Relativity. But in truth,
SR really stands for stupid relativity. SR says that
our reality is a 4-D reality. And yet, there is not
one test to unambiguously establish such a concept.
Not one test! Every test that has so far been
conducted in SR is able to be seen as a simple 3-D
test. Never has any test been conducted that had to
have been a 4-D act. Never, never, never!

4D is just a model. One can e.g. set up Newtonian
mechanics as a 4D system. Or set up SR as a 3D
system (which is what Einstein did in 1905).

O'Barr comments:
And in the 3-D system that Einstein used,
it is just as math perfect as the 4-D system.
And thus: No test can differentiate the
difference.

Of course not, these are merely two different abstractions of
something.

Therefore, the 4-D math that SR experts use
is actually meaningless to the theory.

The set of physical events simply has a natural mathematical structure
of four degrees of certain freedoms. It models the situation exactly
as well as the 3D approach although the 4D formulation is much easier
to deal with e.g. when including gravity in the model.

Thank you, Jan Bielawski. How did you get to be
so smart? And did you note that Einstein used
the LET approach in that there were changes
in lengths, etc.?

No LET. Read Einstein's 1905 paper.
