Assumptions?
perfect rigiidity is what you use to determine a straight line
for accurate measurements and without such perfect rigidity
and "physical measurements", there is no "physical proof".

You have bendy lightwave proof only in anything that uses light beams
to measure stuff that is all messed up with gravity and curving
of the light.
you have a rubber ruler
nothing more.



Relativity limits rigidity, the speed of sound
cannot exceed that of light. This is no exception. A disc moving at
relativistic speed will expand because it is elastic. The fucticious
light inextensible string must in a relativistic context have a speed
of sound = c.

Yes,
limit rigidity so the "theory" can not be wrong to itself".



In point of fact in real life (the non ideal case) odd things happen
when we exceed the speed of sound NOT light.

Very true, but not odd enough that classical stuff, when done
correctly, does show "how" it all happens like such.


Odd point - a civil war bullet (slower than sound in water) travells
further in water than high velocity bullets which all disintegrate.

slow and efficient.. wins the race..
the turtles are everywhere!
