"ABSTRACT

The classical phenomenon of the redshift of light in a static
gravitational potential, usually called the gravitational redshift,
is described in the literature essentially in two ways:

on the one hand the phenomenon is explained through the behaviour
of clocks which run the faster the higher they are located in the
potential, whereas the energy and frequency of the propagating photon
do not change with height. The light thus appears to be redshifted
relative to the frequency of the clock.

On the other hand the phenomenon is alternatively discussed
(even in some authoritative texts) in terms of an energy loss of
a photon as it overcomes the gravitational attraction of the massive
body. This second approach operates with notions such as the
"gravitational mass" or the "potential energy" of a photon and
we assert that it is misleading.

We do not claim to present any original ideas or to give a
comprehensive review of the subject, our goal being essentially
a pedagogical one."


Let's consider that photons loose energy as they overcome the
gravitational attraction of the Earth:

A light signal of frequency Nu1 is emitted by an atom at rest on the
surface of the earth. The energy of a photon is thus E1 = hNu1 and
its "mass" m = E1/c^2 = hNu1/c^2.

At a height H, i.e. at a distance d = Rearth + H from the Earth's
center, the frequency of the received signal is Nu2, hence the
photon's energy is E2 = hNu2.
Its potential energy is Ep = m * gm * H, where gm = GMearth/(Rearth*d).
From E2 = E1 - Ep, one gets

hNu2 = hNu1 - hNu1/c^2 * GMearth/(Rearth*d) * (d-Rearth)
Nu2 = Nu1 * (1 - GMearth/c^2 * (1/Rearth - 1/d)
The corresponding shift Nu2/Nu1 - 1 = -GMearth/c^2 * (1/Rearth - 1/d),
which is a redshift.

The same shift would be obtained using GR.

To simplify, one could consider, like the authors of the paper did,
that g is approximately constant when H is small.
Then Ep = m * g * H = hNu1/c^2 * g * H (where g = GMearth/Rearth^2)
hNu2 = hNu1 - hNu1/c^2 * g * H = hNu1 (1 - g*H/c^2)
The shift then reduces to -g*H/c^2.

It is easy to show that the interpretation according to which
"clocks run the faster the higher they are located in the
potential, whereas the energy and frequency of the propagating photon
do not change with height" is wrong.
It suffices to consider the case when the signal receiver is freely
falling.

Excerpt:

"Consider now another situation, when the upper atom (absorber) moves
in the laboratory frame with a velocity v = gH/c downwards. Then in
the elevator frame it will have zero velocity at the moment of
absorption and hence it will be able to absorb the photon resonantly
in complete agreement with experiments [4, 5]. Obviously, in the
elevator frame there is no room for the interpretation of the redshift
in terms of a photon
losing its energy as it climbs out of the gravitational well."

In such situation, for the freely falling absorber, the signal emitted
from the ground would appear *Doppler blue shifted* by gH/c^2 if it
were
not *beforehand* red shifted by gH/c^2 by "the gravitational attraction

of the massive body". Iow, for the absorber, the signal is not shifted
at all. This is a logical proof that the signal is red shifted when
it leaves the emitter.

If according to GR you maintain c constant, and that a higher clock
runs faster and the frequency is reduced on the way out of a gravity
well, you will calculate a double redshift.

What really happens is that the lowerclock will run slower, the
frequency (and energy) of emission is lower and does not change, but c
increases out of the well, so that the wavelength stretches to give
redshift, without change in frequency.
A comparative higher test clock will see single redshift, because
Nu1as emitted is constant and the higher Nu2 of the upper clock
detects the redshift. (With the latter true I don't also need a
reduction in Nu1 or I get 2 shifts).

Dropping clocks mean nothing; the intensity of the gravity in the well
is the environment that governs clock rate, irrespective of
acceleration. See my website.

That is correct.

LUTGENS:

It is easy to show that the interpretation according to which

"clocks run the faster the higher they are located in the

No, that is correct when using a universal reference frame; and the above
article explained it rather well! (It appeared in the AJP if I'm not
mistaken).

This proof falsifies Einstein's view:

I'm sorry, Marcel. I don't see any conflict.

what redshift

yo misiterpret light bein a wave

it cant be wave in no medium

wave is pressure - underpressure variation
in a medium

take 1d pde equation relating directly to
strings for instance, ther is pressure -
underressure / tension variations in
the material makin up the string

yo can detect tha 1d wave yo being
in a 2d or in 3d

take tha 2d wave pde eqn relatin directly to
the surface of water for instance, the pressures
underpressures takes place again in tha
water material, tha molecules are in pressure -
underpressure also deeper into tha material
not only at surface, but is okay becus only 2d

so yo can see 2d from 3d

in 3d the waves are spherical, 100% plane not
pussible, to see this yu need 4d but yo only have
3d, so yo cant see

light as wave is impossible

its an artifact hundred procent for sure, unless yo
consider propagation thro ether

For a freely falling absorber, the signal emitted from the ground

Just consider that the moving masses in the atoms have to
