NO ! You confuse the fact that the frames axis are chosen in order
to make B move on the "+x" direction in A (which is of no consequence)
with the fact that THEN any kind of movement (even non-uniform ones
btw) can be studied !

It does

Silly ! It depends on "w", where does this f***g specif light
ray come from ? There is no specific light ray to consider when
you define how two frames relate to each other !

This is what scientists call
"scientific time".

NO.

Yes. If light is emitted in A and B, as you define them, at x1,y1,z1
in A and x1',y1'z1' in B, then the light will propagate as a sphere in
A with a radius of wt. That means that a photon can be going any
direction. It will travel a distance of ct in whatever direction it
is going, and its position at a time of t can be given by its
coordinates, x,y,z. In frame of reference B, regardles of what the
source of light does relative to B after the light is emitted, there
will be a group of photons emitted in all directions at x1',y1',z1'.
These photons will propagate as a sphere with a radius of wn', where
n' is time on a clock in B.
So if you want a specific light ray or photon, you just pick one
out. There are plently to choose from. You boys claim to be able to
do this using the Lorentz equations. What makes it so hard with these
equations?
