Nor do I, explain it to me.

I'm not thru, it's too early to give an answer.
Basically I accept SR and GR as long as nothing better explains what
is going on.
( I know also your objections against Einstein and your simple calc.
for the Sagnac exp. which shows correct results )
Still I find it not logic, but math. correct (this statement is indeed
also not logic, because math. is the pure logic), that distances must
shrink to fulfill the c=constant axiom for a moving frame and for
others the same distance remains unchanged.
This Java applet therefore, with the fixed x-axis for the B's view
again lead me to think about.

If I take 1. c=constant in all frames and
2. s = constant in all frames
3. t=t'.gamma
4. v=s/t, v'=s/t', beta=v/t, beta'=v'/c the rest of
the formulas is selfexplaining including the sinh function for
distances after constant acceleration. But I derived this years ago
and are not firm at the moment to explain it in detail (the age, you
may know.... )

c can be any value between the frames in *my transformation*. This is
exactly as weird as c=c+-v, which is not explained to date how this
can happen and is the basis for this group. This is the key point for
me.
Otherwise there would be no room for discussions in this group.
Especially for you c is not constant, if I understand right.

But again, I'm not thru and as I have not to loose any credibility
take this also as weird.
So for all reading this don't take it serious and stay friendly.
