That leaves objects fortuitously changing shape to preserve
imagined properties of never detected particles. But
heck, if religion isn't good for things like that what
use is it?

Still haven't found any study time I see.

There is no 'MMX math' .. There is the math of the various theories that can
be used to explain it .. the math depends on the theory.

Are you unaware of how science works?

Nope .. but its not surprising that you don't understand

Haven't you? Not surprising as all you seem to do is hunt for quotes and
links, and never know what is relevant .. as shown below ...

We were discussing (primarily) SR. You should study it yourself some time

I plan to do that just as soon as I complete my studies
of Caloric Theory. :-))

In principle (as follows from this "gedanken"), those effects should
be measurable with the chosen coordinate system in which the sun is in
rest.

Do you mean that some people pretend that Einstein was *not* an SRT

I take not that you also did not comment on his claim.
