The speed of light is always determined to be 'c'.

So in all inertial reference frames the speed of light in a vacuum is c,
according to you?

As determined by Observers in the inertial reference frame, yes.

As determined by Observers in the inertial reference frame, yes.

Terrific. So you agree that the speed of light is constant in all inertial
reference frames, and disagree with the subject line of this post. You
should be telling the OP why he is wrong.

But what I do not think the OP understands is the reason why. The
reason why is due to the difference in the rates at which the clocks
'tick' as the synchronized clocks are moved to A' and B' from M'. As
the clock is moved to B' it is being moved against the 'flow' of the
aether and 'ticks' slower than the clock being moved to A'. That is
how the Observers on the train determine the speed of light on the
train to be 'c'. But the light travels at 'c' with respect to the
aether and in the scenario I described in my earlier posts the light
is traveling at 'c' with respect to the aether at rest with respect to
the embankment. If the Observers have this information they will then
be able to determine the light travels at 'c' from B to M' and from A
to M'. So, it depends on the information the Observers on the train
have which allows them to determine where the light travels at 'c'
with respect to and to determine where the light travels at 'c' with
respect to the aether to M'.

But what I do not think the OP understands is the reason why.

________________________________
You can invent any explanation you like, as long as it is consistent with
the observed fact the speed of light in a vacuum is a constant. I assume
you also agree with all the other predictions that SR makes? If not, are
there any you disagree with?
