VERGON:

Right. And SR "predicts" that if you observe a clock in motion it will
register
dilation time [[[ t' = t sqrt(1 - v^2/c^2) ]]]. IT ALSO PREDICTS that
this is true regardless of direction.

Now astronomers observe moving clocks every night. We have here
EMPIRICISM.
And they observe approaching clocks to run fast. So where does that
leave you and your dogmatism? Physics doesn't care about that either.

Vergon:

Wrong assumption. I did just that. You should be careful as to what is
"obvious" to you.
