No. The frequency and wavelength of a light pulse, as well as energy in
general, are not invariants -- they depend on the way one measures them.
For instance, Doppler shift changes both frequency and wavelength of a
light pulse or beam.


What does the gravitational redshift change Roberts Roberts? Again
frequency and wavelength? Or frequency and speed of light? If it
changes frequency and speed of light, why does Doppler shift change
frequency and wavelength:

http://www.physlink.com/Education/AskExperts/ae13.cfm
"So, it is absolutely true that the speed of light is _not_ constant
in a gravitational field [which, by the equivalence principle, applies
as well to accelerating (non-inertial) frames of reference]. If this
were not so, there would be no bending of light by the gravitational
field of stars. One can do a simple Huyghens reconstruction of a wave
front, taking into account the different speed of advance of the
wavefront at different distances from the star (variation of speed of
light), to derive the deflection of the light by the star.
Indeed, this is exactly how Einstein did the calculation in:
"On the Influence of Gravitation on the Propagation of Light," Annalen
der Physik, 35, 1911.
which predated the full formal development of general relativity by
about four years. This paper is widely available in English. You can
find a copy beginning on page 99 of the Dover book "The Principle of
Relativity." You will find in section 3 of that paper, Einstein"s
derivation of the (variable) speed of light in a gravitational
potential, eqn (3). The result is,
c' = c0 ( 1 + V / c^2 )
where V is the gravitational potential relative to the point where the
speed of light c0 is measured."

http://www.blazelabs.com/f-g-gcont.asp "The first confirmation of a
long range variation in the speed of light travelling in space came in
1964. Irwin Shapiro, it seems, was the first to make use of a
previously forgotten facet of general relativity theory -- that the
speed of light is reduced when it passes through a gravitational
field....Faced with this evidence, Einstein stated:"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."......Today we find that since the Special
Theory of Relativity unfortunately became part of the so called
mainstream science, it is considered a sacrilege to even suggest that
the speed of light be anything other than a constant. This is somewhat
surprising since even Einstein himself suggested in a paper "On the
Influence of Gravitation on the Propagation of Light," Annalen der
Physik, 35, 1911, that the speed of light might vary with the
gravitational potential. Indeed, the variation of the speed of light
in a vacuum or space is explicitly shown in Einstein's calculation for
the angle at which light should bend upon the influence of gravity.
One can find his calculation in his paper. The result is c'=c(1+V/c^2)
where V is the gravitational potential relative to the point where the
measurement is taken. 1+V/c^2 is also known as the GRAVITATIONAL
REDSHIFT FACTOR."

Zombies are getting more and more enigmatic. Why are you referring to
this Wormley? To show that some hypnotist in Einstein criminal cult
has camouflaged the issue by defining the gravitational redshift in
terms of wavelength? When Pound and Rebka measured the gravitational
redshift, what did they measure Wormley? Frequency? Wavelength? Master
Tom Roberts wants to tell you something:

Tom Roberts: "Pound et al used the 22-meter Harvard tower, using the
Moessbauer effect to obtain the requisite resolution. The others use
atomic clocks. None of the above measured wavelength directly. But we
do know that on earth the speed of light is c, and in the GPS the
speed of light is c between satellite and ground." Tom Roberts

Hey Pentcho--The speed of light is constant. In the case of GPS, the
Relativistic Effects on Satellite Clocks is discussed at
http://relativity.livingreviews.org/...age=node5.html

Say "OK Sisco".


Wormley Wormley in the above quotation Master Tom Roberts says "we do
know that on earth the speed of light is c" because otherwise zombies
may realize that the frequency variation in a gravitational field is
due to the fact that the speed of light varies with the gravitational
potential; then zombies may ask "Is the frequency variation in the
Doppler effect also due to some variation of the speed of light?" and
this leads to adieu Einstein etc. After learning what Master Tom
Roberts has taught them, zombies say, as you do, "Hey Pentcho--The
speed of light is constant".

However Master Tom Roberts knows his zombies so the next day he may
say:

Tom Roberts wrote in sci.physics.relativity:
Pentcho Valev wrote:
CAN THE SPEED OF LIGHT EXCEED 300000 km/s IN A GRAVITATIONAL FIELD?

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


Zombies would learn this new truth enthusiastically and if necessary
would say: "Hey Pentcho--The speed of light is variable".

Are these Zombies anything like Brad Guth's Zions, perchance?

We have already discussed your lack of understanding of physics (and
the sites you quote) in alt.sci.time-travel. Unless you have taken a
real physics course, you really have no right to impose your delusions
on real physicists.

If you have a question, fine. But you are not a scientist and should
take your non-science to a non-science NG.

Respectfully submitted,

Yes I do have a question. Some time ago you initially said Einstein's
1911 equation c'=c(1+V/c^2) is "nonsense" but then changed your mind
and deduced the equation c'=c from the "nonsense":

http://groups.google.ca/group/sci.ph...097ec7018a32a?

Pentcho:
"Does the speed of light vary in a gravitational field in accordance
with Einstein's 1911 equation c'=c(1+V/c^2) which, in the absence of a


The TimeLord:
"What's the reference for this formula? As far as I know Einstein
never said this nonsense. (The second axiom for SR is that c is the
same for all reference frames.).....Besides, if you take c'=c(1+V/c^2)
and take away the gravitational field, then V=0 and c'=c, not c'=c+v.
Simple!

This simplicity of science amazed me and I asked you to consult Master
Tom Roberts:

Pentcho:
"You do not think anymore Einstein's 1911 equation c'=c(1+V/c^2) is
"nonsense". Good. Concerning your discovery that c'=c(1+V/c^2) leads
to c'=c and not to c'=c+v and that this is just "simple", ask Master
Tom Roberts, e.g. in the following way: "Oh Master Roberts, oh Albert
Einstein of our generation (Hawking has NEVER been the Albert Einstein
of our generation), is science really so simple?"

Did you consult Master Tom Roberts? What did he say about simplicity
of science?
