I wasn't asking if you believe that rulers and clocks actually change
this way, I'm just saying that *if* they change this way, different
reference frames will get different measurements.

If pigs could fly they'd be pigeons.


Are you saying it is logically impossible that rulers could shrink and
clocks could slow down depending on their velocity?

Yes.


Note, again, that if all the laws of physics are Lorentz-invariant,
then all physical rulers *must* shrink and all physical rulers must
slow down.

Which is logically impossible. So forget Lorentz invariance, it is
sci-fi.

Show me the evidence.


The evidence of what?

Rulers shrinking.



The evidence that rulers and clocks actually do change in this way?

Yes. Show me the evidence.


Or are you just asking me to prove that *if* we assume they change in
this way, then it is possible to prove that K's rulers and clocks will
measure the distance expanding at c-v, while k's rulers and clocks
will measure the distance expanding at c?

Couldn't care less what you "if" about. Show me the evidence.







If V = (c+v)/(1+v/c) then use that to derive the LTs.
If the system of equations is linear as Einstein claims, it shoud be
no trouble.


Where are you getting V = (c+v)/(1+v/c)? That's not an equation I can
remember seeing.


§ 5. The Composition of Velocities

You don't know very much about relativity, do you?
Why are you talking to me as if you did?


The law of composition of velocities given in section 5 is V =
(v+w)/(1+v*w/c^2). If you plug in w=c, then you'll get the equation
you posted above, but why would you expect me to recognize a specific
case of a general equation for velocity composition, when you provided
no context whatsoever?
I quoted verbatim.
I'm not going to continue a conversation with somebody that challenges
my integrity when I quote Einstein.
