Regarding Einstein’s train gedanken depiction of the Relativity of
Simultaneity.
In ‘Relativity the Special and General Theory’ Einstein points out
that from the stationary observer’s point of view (M) flash B (toward
which the train is moving) will reach the passenger before flash A..
Will flash B arrive at the passenger’s location at the same point
relatively to the platform as seen by the stationary observer?
No, of course not. The train moves along the track, carrying the
passenger with it, while the light signal propagates.
Here, does this help?

I think one of us may have misunderstood the question.
Apparently, and I have no doubt who. Hopefully the link to the
animation will answer the question for the OP anyway.
I have a video that shows the Wicked Witch of the West
melting so I have never doubted that witches can do that.
If you have a video that shows light moving as a massive
particle, then it must be true.

But it doesn't move as a massive particle. Massive particles don't
move at c.

Are you claiming light is a particle? There is money in
it it for you if you can prove it.
<<Now, does not the prize to Einstein imply
that the Academy recognised the particle
nature of light? The Nobel Committee says
that Einstein had found that the energy exchange
between matter and ether occurs by atoms emitting
or absorbing a quantum of energy,hv .
As a consequence of the new concept of light quanta
(in modern terminology photons) Einstein proposed the
law that an electron emitted from a substance by
monochromatic light with the frequency has to have
a maximum energy of E=hv-p, where p is the energy needed to
remove the electron from the substance. Robert Andrews
Millikan carried out a series of measurements over a
period of 10 years, finally confirming the validity of this
law in 1916 with great accuracy. Millikan had, however,
found the idea of light quanta to be unfamiliar and strange.
The Nobel Committee avoids committing itself to the
particle concept. Light-quanta or with modern terminology,
photons, were explicitly mentioned in the reports on
which the prize decision rested only in connection with
emission and absorption processes. The Committee says
that the most important application of Einstein's photoelectric
law and also its most convincing confirmation has come from
the use Bohr made of it in his theory of atoms, which explains
a vast amount of spectroscopic data. >>

Thanks for that reference but as far as I can see it says |
nothing in relation to my question as it only relates to
the stationary observer and the passenger.
