Albert Einstein, "Relativity", Chapter 22 :

"In the second place our result shows that, 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 and to which we have already
frequently referred, 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."

Assume the photon occupies consecutively three positions where its
speed is:

(A) Position 1: 300000 km/s
Position 2: 300000 km/s
Position 3: 300000 km/s

(B) Position 1: 300000 km/s
Position 2: 300001 km/s
Position 3: 300002 km/s

Which scenario - A or B - is consistent with Einstein's text? There is
an epitaph at the end of the second scenario.

The curvature of rays of light, eg due to the effect of gravitational
fields, is described by General Relativity.

By the way since velocity means speed+direction, light can change its
velocity without changing its speed.

Neither, since Einstein being a mere phycist merely
followed the Newton rules of interia to derive his SR.

And quite obviosly missed the significant point that
in QM, it's a finite field over E and M, and
cosines of velocity deflections, and has nothing to do with C.

By the way since velocity means speed+direction, light can change its
velocity without changing its speed.

Webster's Encyclopedic Unabridged Dictionary: Velocity: 1. rapidity of
motion or operation; swiftness; speed: [to measure the velocity of the
wind.] 2. [Mech.] the time rate of change of position of a body in reference
to a specified direction. 3. the rate of speed with which something happens;
rapidity of action or reaction.

Light CANNOT change velocity without changing its speed. Velocity is
speed. Time has more than one dimensional characteristic though. Relativity
has more than one dimensional characteristic. Light will never change
velocity from its constant, but [relative] time can be shattered to infinity
upon that rock (have an infinity of different measurements). Thus when we
say "300,000 kilometers per second" is constant, it is constant. 300,000
kilometers and one second, though, may be relative, expansive or
contractive, the space-time being expansive or contractive. Which is why we
see things expand (oncoming in space-time) or contract (going away in
space-time) with regard to distance-time, which doesn't get into the math;
doesn't have any place in the math. The velocity won't be broken down, won't
change. Wavelengths and frequencies of the light are an entirely different
matter.

An observer behind an object going away at velocity will see a different
wavelength of light for the object than an observer to which the object is
oncoming. The observer behind sees contraction of the object and lengthening
of time (or slowing down). The observer ahead sees expansion of the object
and shortening of time (speeding up). The object, or traveler, observes
both, one behind and the other ahead. The speed of light does not change for
any of the observers, it is the one constant in the whole picture, thus
causing all these observational differences.

You do not observe a titanic train oncoming in the distance that becomes a
mere fly spec upon reaching your immediate location. Nor do you observe
other weird things routinely. If the speed of light were not constant you
would probably observe either a titanic train oncoming in the distance that
is still just as visibly titanic upon reaching you, or a massless fly spec
of a train in the distance that remains visibly a fly spec of a train,
though now a massive fly spec, upon reaching your immediate location. The
world and the universe would be some kind of hellish cartoon world and
universe gone berserk.

Time actually neithers lengthens nor shortens, since the speed of light
will always be constant. But time will include innumerable other times
through an expansion for a traveler, or exclude them just as easily via
contraction as a traveler becomes more relative to fewer of them, or
relative to just one of them finally. We don't observe space, it is
simultaneous -- thus unobservable, what we observe are innumerable times
(innumerable histories) as differing time composits we would call
"space-time frames." If physicists really knew what the above was all about,
they would have no trouble realizing a merger of Relativity and QM. They
don't though because they do not expand and contract time properly. They do
not make time inclusive of times and also exclusive of them. They do not
make a second inclusive of seconds, yet it still being the same second as
those included. They do not make a kilometer, or a mile, inclusive of
kilometers or miles, yet it remaining the same kilometer or mile as all
those included. They do not deal in universes within universes within
universes, fields within fields within fields. "300,000kps" is also a field
capable of inclosing identical fields within itself, being thus both
expansive and contractive field without losing a bit of its constancy, its
consistency, its coherency, no matter what. As I see it, we observe the
differences between utterly self-similar -- composited -- fields as many
differences in wavelength and frequency.

"c" can get almighty expansive to enclose and become inclusive of "c". Or
it ("c") can contract spinning off "c" here, spinning off "c" there, "c"
ever remaining coherent.

This is simply wrong, as the 2nd chapter of any physics textbook will
point out to you. The definition that applies is definition [2]. As an
exercise, the reader should verify that in circular motion, for
example, at constant speed, the time rate of position of a body in
reference to a specified direction is *changing* -- hence there is
nonzero acceleration.

Velocity is a *vector* with magnitude (speed) and direction. Changing
either the magnitude or the direction or both, constitutes a change in
velocity.

You misunderstand the trajectory in this case. The photon speed (more
precisely, the light ray's speed as this is not QM) at a single moment in
time is a function of its normal coordinates (perpendicular to its
trajectory), which causes Huygens bending (Einstein 1916).
In simple words: the bottom of the ray propagates slower than the top of the
ray.

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.
