The fundamental INHERENT AMBIGUITY in general relativity according to
Honest Roberts:

Tom Roberts Jan 29 2008:
"There are several ways to interpret such a physical situation:
A) the photon gains energy by falling in the gravitational field.
B) the photon is blueshifted due to its travel between heights in the
gravitational field.
C) the energy scales of atom and detector are different, due to their
difference in gravitational potential; the photon does not change
energy (or frequency) during its journey, but it registers more energy
in the detector due to change of scale (time scales also differ).
All three interpretations are valid, and correspond to using different
coordinate systems to describe the physical situation. So one cannot
say unambiguously that the photon does or does not change energy, does
or does not change frequency, or that the scale of energy does or does
not change with height.
At base, the difference is due to the non-local nature of this
physical situation in the gravitational field, and the difficulty
(INHERENT AMBIGUITY) in GR of describing non-local situations. This is
traceable to the problems of doing integrals on curved manifolds, and
the result is that energy is conserved only locally in GR.
But there is an approximation that is often appropriate: if a system
is localized in spacetime and has no outside interactions, then one
can draw a closed boundary containing the system, with no energy or
momentum crossing the boundary and the manifold is asymptotically flat
there -- then inside the boundary the total energy and momentum are
conserved. This applies to the original three situations, but one
cannot draw such a boundary between the emitter and the detector in
this last situation." Tom Roberts

Clearly the fundamental INHERENT AMBIGUITY in general relativity
camouflages the fact that, in a gravitational field, the speed of
light is VARIABLE and obeys the equation c'=c(1+V/c^2) given by
Newton's emission theory of light, a fact experimentally confirmed
when Pound and Rebka measured the gravitational redshift factor 1+V/
c^2:

"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."
