Relativity hypnotists wish to know why Einstein was silent about
momentum and mass of the photon:

Other hypnotists have provided the answer:

"Einstein went on to discover a more general theory of relativity which
explained gravity in terms of curved spacetime, and he talked about the
speed of light changing in this new theory. In the 1920 book
"Relativity: the special and general theory" he wrote: . . . according
to the general theory of relativity, the law of the constancy of the
velocity of light in vacuo, which constitutes one of the two
fundamental assumptions in the special theory of relativity [. . .]
cannot claim any unlimited validity. A curvature of rays of light can
only take place when the velocity of propagation of light varies with
position. Since Einstein talks of velocity (a vector quantity: speed
with direction) rather than speed alone, it is not clear that he meant
the speed will change, but the reference to special relativity suggests
that he did mean so."

In other words, the speed of light can be 300000km/s in Position 1,
300001km/s in Position 2, 300002km/s in Position 3 etc. An even more
informed hypnotist, Tom Roberts, explains further in
sci.physics.relativity:

AFAIK Einstein basically thought in German, which does not have
different words for "speed" and "velocity" ("die Geschwindigkeit" is
used for both). Certainly his "velocity of propagation" could be phrased
as "speed of propagation" without changing the underlying physics.

Sure, depending on the physical conditions of the measurement. It can
also be less than "300000 km/s" (by which I assume you really mean the
standard value for c). And this can happen even for an accelerated
observer in a region without any significant gravitation (e.g. in
Minkowski spacetime).
Tom Roberts

Note that the relevant problem is WHETHER THE SPEED OF LIGHT IS
VARIABLE IN A GRAVITATIONAL FIELD, not whether the photon is massless.
The variability of the speed of light in a gravitational field implies
(through the application of the equivalence principle) that the speed
of light in the absence of a gravitational field is c+v, where c is the
speed of photons relative to the light source and v is the relative
speed of the light source and the observer. This means that VARIABILITY
OF THE SPEED OF LIGHT IN A GRAVITATIONAL FIELD IS FATAL FOR EINSTEIN'S
THEORY AND MODERN PHYSICS IN GENERAL:

Albert Einstein:

"If the speed of light is the least bit affected by the speed of the
light source, then my whole theory of relativity and theory of gravity
is false."

"I consider it quite possible that physics cannot be based on the field
concept,i.e., on continuous structures. In that case, nothing remains
of my entire castle in the air, gravitation theory included, [and of]
the rest of modern physics."

Photons can only exist within atoms.
(lacking clocks and monpoles)
The nuclear resonance of the atom at higher altitude
was higher in frequency.
(Pound-Rebka-Snider)

The propagation of light within
the atom, a standing wave, seems consistant with
SR and consistant with GR's prediction for gravity
effects. You get the sign wrong if you take the
'falling photon' model literally.

Indeed... that seems to reduce a theory (GR) to a
mathematical formalism. AFAIK Einstein didn't
consider coherrent matter as a gravitaional mechanism.
Induced fields don't model well without some matter
to induce.

The relaton between particle speed and spin is probaby
more supportive of SR as a theory. Quite the opposite
of what a disclaiming tag like *special* would lead you to
beleive. But then Einstein did every thing upside-down.
That is why signs turn out wrong and the station comes
to the train. :-)
