Sooner or later, Honest Carlip, you and your brothers Einsteinians
will have to explain which prediction, the Newtonian or the
relativistic (giving "a deflection that's twice the Newtonian
amount"), is consistent with the gravitational redshift factor 1+V/c^2
experimentally confirmed by Pound and Rebka:

Honest Roberts why don't you abandon all those red herrings? Just
choose between (1) and (2) below:
(1) The photon behaves like all massive particles: in a gravitational
field, its speed varies in accordance with Einstein's 1911 equation
c'=c(1+V/c^2) given by Newton's emission theory of light:
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....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
"So, faced with this evidence most readers must be wondering why we
learn about the importance of the constancy of speed of light. Did
Einstein miss this? Sometimes I find out that what's written in our
textbooks is just a biased version taken from the original work, so
after searching within the original text of the theory of GR by
Einstein, I found this quote: "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. Now we
might think that as a consequence of this, the special theory of
relativity and with it the whole theory of relativity would be laid in
the dust. But in reality this is not the case. We can only conclude
that the special theory of relativity cannot claim an unlimited domain
of validity ; its results hold only so long as we are able to
disregard the influences of gravitational fields on the phenomena
(e.g. of light)." - Albert Einstein (1879-1955) - The General Theory
of Relativity: Chapter 22 - A Few Inferences from the General
Principle of Relativity-. 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."
(2) The photon is more sensitive to gravity than ordinary massive
particles: in a gravitational field, its speed varies in accordance
with Einstein's 1915 (or 1955) equation c'=c(1+2V/c^2):
http://www.speed-light.info/speed_of_light_variable.htm
"Einstein wrote this paper in 1911 in German (download from:
http://www.physik.uni-augsburg.de/annalen/history/einstein-papers/1911_35_898-908.pdf).
It predated the full formal development of general relativity by about
four years. You can find an English translation of this paper in the
Dover book 'The Principle of Relativity' beginning on page 99; 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+phi/c^2) where phi is the gravitational potential
relative to the point where the speed of light co is measured......You
can find a more sophisticated derivation later by Einstein (1955) from
the full theory of general relativity in the weak field
approximation....For the 1955 results but not in coordinates see page
93, eqn (6.28): c(r)=[1+2phi(r)/c^2]c. Namely the 1955 approximation
shows a variation in km/sec twice as much as first predicted in
1911."
http://www.mathpages.com/rr/s6-01/6-01.htm
"In geometrical units we define c_0 = 1, so Einstein's 1911 formula
can be written simply as c=1+phi. However, this formula for the speed
of light (not to mention this whole approach to gravity) turned out to
be incorrect, as Einstein realized during the years leading up to 1915
and the completion of the general theory. In fact, the general theory
of relativity doesn't give any equation for the speed of light at a
particular location, because the effect of gravity cannot be
represented by a simple scalar field of c values. Instead, the "speed
of light" at a each point depends on the direction of the light ray
through that point, as well as on the choice of coordinate systems, so
we can't generally talk about the value of c at a given point in a non-
vanishing gravitational field. However, if we consider just radial
light rays near a spherically symmetrical (and non- rotating) mass,
and if we agree to use a specific set of coordinates, namely those in
which the metric coefficients are independent of t, then we can read a
formula analogous to Einstein's 1911 formula directly from the
Schwarzschild metric. (...) In the Newtonian limit the classical
gravitational potential at a distance r from mass m is phi=-m/r, so if
we let c_r = dr/dt denote the radial speed of light in Schwarzschild
coordinates, we have c_r =1+2phi, which corresponds to Einstein's 1911
equation, except that we have a factor of 2 instead of 1 on the
potential term."

In essence then, are you are claiming that light travels in an
independent (possibly absolute) frame? That is an interesting assertion
and I'd be interested in how it might relate to the claim that light (in
a vacuum) always travels at the same speed regardless of the speed of
the originating source.
It is no mere assertion. About 100 years
of electromagnetism supports it.

Because a photon is clearly a nonzero mass, is perhaps why gravity
affects their path and the velocity limit of c might be considered.
However, photons of the quantum tunnel or waveguide accommodated kind
seem to ignore such velocity limits.
The supposed ultra cold vacuum of the IGM is still saturated with
Cooper pairs of electrons and perhaps even Cooper positron pairs.

Honest Carlip, any clever teacher in Einsteiniana should immediately
draw the attention of sillier brothers to the following text:
http://xxx.if.usp.br/PS_cache/physics/pdf/0508/0508030v4.pdf
"Einstein’s first calculation of the gravitational deflection of
light, in 1911 (see [4], for a historical account and scientific
references), was performed using the Equivalence Principle and the
equivalent mass-energy of a photon. The calculation yielded δNG. Only
in his second calculation, published in 1916, where he included the
effect of space-time curvature, he obtained a value twice as large as
his first calculation, i.e., δGR [4]."
Then the clever teacher should explain: "Brothers Einsteinans,
Einstein's 1911 calculation based on Newton's emission theory of light
was wrong/correct and inconsistent/consistent with the gravitational
redshift factor 1+V/c^2, Einstein's 1916 calculation was correct/wrong
and consistent/inconsistent with the gravitational redshift factor 1+V/
c^2, but in any case the speed of light in a gravitational field is
VARIABLE. So those who teach you that the speed of light in a
gravitational field is constant are by no means clever teachers."
Pentcho Valev

You know, Pentcho, at some point you should take responsibility for
your own confusion -- and CORRECT it -- rather than pinning the blame
on teachers for your confusion. It's really not a big deal. It happens
to students every day that they misunderstand something that their
teacher said, and you don't find them spending their lifetimes
expressing their outrage at their teachers for their misunderstanding.
PD
And you still have not understood time dilation since the day you
opended Taylor and Wheeler.
Classical physics along the lines of Newton and Maxwell...
Quantum physics along the lines of Planck and Gell-man...
Schizophrenic physics along the lines of Einstein and Dirac...
In the microscopic domain, Quantum physics operates. This reduces to
Classical physics in the macroscopic domain. Thus the general
Schrodinger equation for force reduces to the more specific Newtonian
equation for force.
Schizophrenic physics is merely a child's game of figuring out who is
left holding the stick when the contradictions come in. Thus in the
SR twin paradox, the winner gets to posit that the travelling twin is
able to suspend aging, while the loser is stuck with the dilemma of
explaining how the homely twin was exempted from a supposedly
universal law... Dirac gets to posit a relativistic quantum field
theory... The loser is stuck with renormalization...
1. Did you mean Murry Gell-Mann or some other Gell-man guy?
2. Gell-Mann worked on quantum field theories, despite what your comic
book tells you he did.
3. You tend to repeat elsewhere the same idiocy that has been
corrected before.
I thought the three were as follows:
1. Physics for white people.
2. Physics for black people.
3. Physics for everyone else.

what is misunderstanding by knowing that
the photon has mass

Because Newtonian physics DOES predict that *qualitatively*, just like
you do. But, as has been pointed out to you repeatedly, *qualitative*
is not enough. The Newtonian prediction is *quantitatively* wrong.
Which is enough to say that it is just plain wrong, even
*qualitatively*.
and i indicate dto youmany times that:
the photon is an exception case
*a limit case***
an exception case must be treated
specifically and has some changes
from the extrapolation technique:
(and i have to mention you as well
that any physics formula has
8its limits of validation))
so the exception case need at our case to be calculated specifucally
to that case
it is to be fitted to the experimental data
(and dont you be shocked from my claim of fitting formulas to data
because **that is what GR did as well **
now thejob of fitting the results to Newton and light data
ias not as 'traomatic' or disturbing
as you see it
because it is you youself that
admitted that **qualitatively* it fits the dtata
the additional fitting that is needed is only
**quantitatively **
(not a colplete different approach
physically)
2
the big advantage of douin gmu ssuggestion is
THAT IT DOES NOT NEED
TO INVENT NEW REVOLUTIONARY (NOT TO SAY
FANTASTIC ) NEW LAWS OF PHYSICS
it fits the basics (ideplogic) of the 'old physics)
and that is IMHO a great advantage
3
as far as i heard the difference
between the 'Newtonian calculation and GR calculation is
quantitatively about 2 times magnitude
that is not a fantastic difference
provided as i said
the need to invent new lawas of physics
is a much worse situation !!
4
such thing will fit waht we know
from anotrher experinetal formula
E=hf of which it comes that
the photon energy has mass
and in that case we avoid anothe 'need' to invent a new kind of mass
- 'relativistic mass'
so Mr PD
i consider you a rational physicist
just consider all the above
and try to
**get out of the box **!
if many people like you will join that understanding-- we can open a
new era of advance !!!
(just being able to calculate
physics phenonena
**is not good enough** for advance
we must try and understand better and closer to the *real
cuases *of that phenomenon
btw
i dont have to remind you that i agree with SR !!!

This is where you are DEAD wrong. If you have a measurement
sensitivity of a percent or so, then a factor of 2 is as wide as the
sea, and it is clearly enough to rule out one completely and accept
the other. This is the *whole point* of quantitative experiment -- to
make a measurement with sufficient precision to unambiguously discern
which model is right and which model is wrong.
You have the completely incorrect impression that, once you get a

That is wrong, wrong, wrong, and it is not how science works, nor how
it should work.

you can say 100 times **wrong**

a correction of magnitude 2
is much less wrong than the cheating

there is nothing wrong i fitting formula to data

Uh, no. Quark theory is a QFT. The foundation of quantum mechanics was
laid in the 1920's and 1930's. The quark theory was 3 decades later.
Anything else you'd like to get wrong, as long as you're just making
stuff up?
Quark theory is not relativistic. It just so happens that the current
Standard Model is relativistic and quarks, being the elementary
structure of baryons, are needed in the Standard Model, not the other
way around that quarks need the Standard Model to get accepted.

Oh, this is just precious. Just the kind of thing Strich9 makes a
point of saying day in and day out.
Wait for it....
Wait for it....
Quark theory is governed by the strong force. No gravitation, no
electromagnetic interaction, no weak interaction. Relativity only
dealt with electromagnetic theory (a so-called extension of Maxwell)
and gravitation (a so-called extension of gravitation). Einstein died
without even knowing about the strong interaction or quarks.
But we all know you are schizophrenic and detached from reality, so
feel free to deny this part of reality again... and again... and
again. (Now in Einstein's relativity--appropriately named
schizophrenic physics--an observer can deny the reality of another
since he only goes by what he supposedly computes, not what really
happens in the other observer... this is shown very well in my famous
cosmic ray example, where my aging is denied by the cosmic ray's
supposed computation of my 'other' age.)
That's right. Relativity as EINSTEIN put forward originally only dealt
with those two forces. But since it worked so well in experiment,
subsequent quantum field theories, including the quark model, were all
built to be relativistically covariant from the outset. Keep in mind
that relativity did not end development when Einstein was done with
it, any more than Newtonian physics ended development when Newton was
done with it.
Geez, you are such a loon. Funny, but a loon.

Not "supposed computation". Measurement. That's what physics is about
-- what will be *measured*. You on the other hand say that what is
*measured* in one frame is real and what is *measured* in another
frame is not real. By Decree of Your Royal Highness, of course.

Oh well, renormalization is already involved with the VERY classical
problem of calculating the self energy of a point charge. E.g. read:

Han de Bruijn
Things in the circus get pretty quiet when the clowns are on vacation.
Perhaps someone at the VA finally noticed this guy hasn't done any
work in most of a year, having spent most of his working hours
babbling on USENET.
All of physics is a child's game. Since the entire idiot science
consists of nothing noting but electing mathmeatician cranks to the
International Olympic Committee.
Or since General Relativity consits of nothing but making sure
the kids get to church on time, it's perhpas the most trivial
of sciences.
And Quantum Mechanics mostly consists mostly of educating IBM
loons
how Holograms work, so it is not the most difficilt of subject
