If you want to talk about the reality of a
moving rod's length, then consider this:

A============FRAME A=============B
--------------ROD----------------

In Frame A, cut a ROD to fit between
two points A and B, as shown.

Move the ROD to somewhere else along
the AB line.

Slide the ROD along the line to align
its left end point with point A.

Unless the ROD contracts (or expands)
physically, its right end point must
simultaneously align with point B.

Thus, unless the ROD changes physically,
it could be used to absolutely
synchronize clocks at A and B, thereby
overturning special relativity.

Very Simple Conclusion:
Special relativity contains (implicitly) the
same physical length change as does Lorentzian
relativity, but SR does not admit to this
explicitly.

Questions to ponder:
Does SR also contain actual clock slowing and
actual mass variance?

Sorry, you, or actually anybody, can not "overturn"
special relativity without replacing it with
something ......similar.
SR came to explain experimental evidence.
And it does.
The problems start when we want
to step beyond single events and measurements
in our search for the "universal things"or
mindboggling things like space / time stretching.
Yet , things are not that complicated if
we have the proper approach.
