For 63 years now, it has been proclamed that the 1960 Pound-Rebka
experiment was THE FIRST VALID PROOF OF GR gravitational shift,
with +/- 10% statistical error.

For decades, it was alleged that the Experiment proved right the 1911
Einstein's heuristic assertion that |Δf/f₀| ≈ 20E-15 for an
elevation of
the "light generator" of 22.2 meters above ground.

It's explained EVERYWHERE the cleverness of this duo, that used samples
of radioactive Fe⁵⁷ atoms emitting 14.4 KeV Gamma rays, with a
frequency
of 3.48E+18 Hz (3,480 PetaHz).

And it's claimed EVERYWHERE that the duo measured differences of about
69,660 Hz in that HUGE value of frequency, something that was/is
IMPOSSIBLE with the technology available in the last 60 years (and in
the
next 100 years too).

It's applauded the high degree of ingenuity for using a slowly moving

WHAT HAS NOT BEEN SAID ANYWHERE is that those "clever guys" and his
team of collaborators DIDN'T USE RELATIVISTIC DOPPLER FORMULA, but
used the 160 years old Doppler formula (the one Hubble used in 1929).

So, how is this? Using Newton effects to cancel Einstein effects?
Bullshit.

In this part, I analyze the simple Doppler formula in its two versions.
In the
second part (II), I'll prove that they TRIMMED, COOKED AND FUDGED the
data of the experiment to obtain 14 values (out of thousands) TO FIT
"EINSTEIN'S PREDICTION".

BUT THEY CLAIMED THAT THE LINEAR VELOCITY OF THE SWINGING
SAMPLE WAS ABOUT 1 cm/sec, not 1,000 times lower than that!

So, the relativistic gravitational shift is BARELY NOTICED:

The above calculations are a proof that the NARRATIVE about the "shift
cancellation" by using classic Dopler effect to CANCEL the einstenian
relativistic blue shifting is JUST A FAIRY TALE.

Any measurement of such calculations was IMPOSSIBLE TO BE MADE in
1960 and for the next 40 years.

What Pound & Rebka CLAIMED THAT MEASURED was below the values to
be cancelled (about +/- 15E-15).

The ALLEGED speed v of the sample, in the direction of the detector had
to
be around 4.55E-04 cm/sec, not the claimed 1.5 cm/sec.

Wikipedia estimates that v ≈ 7.5E-05 cm/sec.

The ABSOLUTE AVERAGE frequency shift had to be around 69,600 Hz,
difference IMPOSSIBLE TO BE MEASURED BY ANY MEANS on 3.48E+18 Hz
(3,480 PetaHz) frequency of Gamma ray photons.

So, WE ARE SUPPOSED TO BELIEVE that the 14 carefully selected
measurements that they published are ABSOLUTELY TRUE, even when
they have a FUDGE COMPENSATION FACTOR FOR TEMPERATURE that
is ALMOST THE MEASURED VALUE. As an example, this measurement,
as published:
>
Feb. 22, 5 p.m. ; Source at the bottom.
Shift observed: (-11.5 ± 3.0) x 10E-15
Temperature correction: -9.2 x 10E-15 (almost 90% cooking/fudging)
Net shift: (-20.7 ± 3.0) x 10E-15 [as predicted by Einstein]
>
NOTE: Photons without recoil are a tiny fraction f of the total amount
of
Gamma photons emitted. And this fraction has frequency shifts that are
SPREAD, in a gaussian way, around f₀ ± 34,800 Hz CALCULATED, not
measured.

Now, anyone wanting to redo such experiment today will have to justify
PLENTY how did they measured such uber tiny difference in 3,480 PetaHz.

No way then, and even today, unless you resort to fudging and
statistical
HEALING.

Next part will be about the 14 published measurements, as the one above.
