but Consistent with Wallace's analysis of radar data.
Consistent with Pioneer data.
Consistent with light curves from some binary sources.
You pays your money and takes your choice.
If an experiment threatens the status quo i.e. neutrinos breaking the
speed limit the experiment is subject to proper critical analysis by
people who have an incentive to discredit it. If an experiment appears
to show what physicists want to hear it is accepted willingly and
published without difficulty. This has been happening since relativity
was first published.
De-Sitter for example 1913 is one such, still quoted yet easily
dismissed. What you have is a distant star system at a point O.
You have no independent verification of what is there only data and that
is somewhat fuzzy.
De-Sitter assumed relativity to be correct and worked out a description
of what was at O consistent with relativity (this is easy to do if SR is
correct).
Let us describe that description as D(r) (the description of what is
there based on the assumption of the truth of relativity)
What De-Sitter assumed was that D(r) is an accurate description of
what actually is at O. He argued that as D(r) is an accurate
description, if Emission theory were true it would not produce the data
- so emission theory can't be true. A totally circular argument but very
welcome to those who wanted their beliefs to be confirmed.
To test if Emission theory is correct it is necessary to try and
discover a different description D(e) of what is at O which, if emission
theory is true, would result in the known data. This is exceedingly
difficult. It requires that one makes a guess at what is at O, calculate
what data would result if emission theory is true, compare it with the
actual data then by an iterative process make modifications to the guess
until a match is achieved. This process is hard enough when you have a
computer. DeSitter's slide rule would not be up to the task.
I should also mention that DeSitter was selective in choice of data sets.
No one looked critically at the H&K experiment except Essen who designed
the atomic clocks and knew more about their characteristics than anyone
else on the planet. The assumptions H&K made were wrong and the accuracy
wasn't as good as they claimed for clocks used in that manner.... but
why spoil the party? The journal which published the experiment refused
to publish Essen's criticism. A few decades later the raw data was
released and proper analysis showed it to be inconclusive.
Wallace showed that a massive unexplained error in radar data
disappeared if you assumed light speed is c+v. A subset of the data,
incapable of showing this effect was retained and the rest deliberately
destroyed. Wallace's work was passed off as insignificant because of the
small data sample.
The Alvager Nilsson and Kjellman experiment 1963 concluded that the
invariance postulate was verified. Unfortunately Waldron showed their
actual published figures supported emission theory. Alvager had another
go in 1964 and this time he got the "right" answer - it is this later
paper which is quoted. This was a fore-runner of Fox & Filippas. Those
doing the experiments are not objectively, without bias, trying to
determine whether or not light speed is source dependent their one
objective it is to show that it is *not* so as to gain the approval of
their peers and theirs be the experiment always quoted. That is why Fox
looked at Ritz's emission theory. Not to see if it was viable but to
attempt to show - successfully - that evidence against it did not stand
up to close scrutiny. In other words to discredit previous evidence
(including Alvager) so that his would be quoted as the first experiment
to justify physics adoption of SR and its rejection of the simpler
Emission theory.
