It has nothing to do with the BaT.

Try this:
Build a monochromatic source and two identical filters which are
transparent to that frequency/wavelength only.
Place the source and one filter on a rocket, and leave the other
behind.
With the rocket at speed ref earth, split the source beam, sending one
half straight to earth, and the other through the filter --> earth.
What do you think will be noticed? Remember, for both to make it to
earth AND through the earth based filter, we know that there CANNOT
have been a doppler shift between the source and the space based
filter, or the beam would have been blocked there!........or did these
amazingly talented photons KNOW to change their f/u AFTER passing
through the space filter????????

Jeff seems to be (subliminally) aware of what is actually happening
to/on the train, when he mentions that SR describes the relationship
between the observers , and the "observed" ONLY! This suggests that he
realises that the "measurements" are due to the illusions produced by
an object's velocity, and how the finite nature of information transfer
by way of emr distorts the true situation to these observers.
My position is, that although emr is ubiquitous throughout the universe
in varying "densities", the "universe" doesn't give a shrug whether
information is transfered or not, and WHAT puny humans wrongly perceive
and deduce. Objects still exist for the blind, and distance exists
between bodies, whether emr passes between them or not. Similarly,
velocity of, and that of other objects transitting from one to the
other, also "exists".
If we are denied the emans to measure it, tough! The universe doesn't
care.
Observers are mistaken. AE was such an observer.

Obviously, both beams reach Earth, and neither beam will
go through the filter on Earth.

That obviously can't happen.

That obviously can't happen, either.

If you and the light source are moving apart, you observe
a lower frequency because each wave starts its journey
from a little bit farther away. Simple geometry.

I didn't just mention it, I explained it to you.

So all measurements of things in motion are due to
illusions? That's what you just said.

I thought you were beyond that. You complained when I
brought it up.

The time delay is not what causes a photon or dropped ball
to have a diagonal path in the train thought experiment.

Nancy? Is that you?

Obviously.

Virtually everything you say is either kindergarten
obvious or bonehead wrong.

Obviously.

You have not shown that in any of your arguments.

An observer will be mistaken in the way you suggest only
if he is even stupider than you are.

> AE was such an observer.

You think Albert Einstein was stupider than you?

Do you want to demonstrate how smart you are?

OK, that's clear.

Good question so far but you should have left
it at that.

That is correct, you just gave half the answer.

The filter on the ship is not moving relative to
the source so there is no Doppler shift and the
second beam passes through. Both beams leave the
craft.

The second part is what happens on Earth which
you didn't address. When they reach Earth, it
is moving relative to the source so the Doppler
effect means neither beam passes through the
Earth filter.

Your subsequent comments don't seem related to
the above question at all and I can't for the
life of me imagine what point you think this
gedanken makes.
