It doesn't matter whether
the source is a gamma burster, a tungsten filament, a laser, a
radar antenna or an excited nucleus. Even neutrinos travel at
speeds so close to c that the difference between neutrino speeds
and c is almost immeasurable over interstellar distances.
It is as if emission theory demands that the atomic equivalent of
rifles, slingshots, bows, air guns and punkin chunkers shoot out
bullets, rocks, arrows, BBs and pumpkins at the same constant,
universal speed c, despite the fact that the firing mechanisms of
these different projectile shooters are all entirely different,
and speed "c" holds no special status in emission theory.
So what is your answer, Androcles?
===============================================
My answer is: your question includes a false assumption so I will not
attempt to answer it, you deranged fuckin' idiot.
===============================================
How interesting!

The premises of emission theory, as I had always understood it,
are as follows:
1) Light travels at a speed of exactly 299,792,458 m/s relative
to its source, a speed which is designated as "c".
2) If a source is traveling at a speed of v relative to an
observer, then the speed of light measured by the observer
is c+v.

You appear to be claiming the following:
1) In 1935, Michelson et al. found that light emitted by an arc
lamp did not travel at a single constant speed, but rather
showed a total spread of velocities of over +/- 50 km/s from
the central value. "There were made 2885.5 determinations of
the velocity, the simple mean value of which is 299,774 km/s,
with an average deviation of 11 km/sec from the mean."
http://articles.adsabs.harvard.edu//full/1935CMWCI.522....1M
2) This spread in velocities is fully in accordance with the
expectations of emission theory. Arc lamps are very hot
sources, and light from arc lamps therefore exhibits a large
and totally expected doppler spread.
3) Light is therefore emitted at APPROXIMATELY 299,790,000
from real sources, the central value being designated as "c".
4) If a real source is traveling at a speed of v relative to an
observer, then the speed of light measured by the observer
is APPROXIMATELY c+v.

Leaving aside the question of whether you have interpreted
Michelson et al.'s paper correctly or not... It STILL doesn't
matter whether the source is an arc lamp, a tungsten filament, a
laser, a radar antenna or an excited nucleus.

It is as if emission theory demands that the atomic equivalent of
rifles, slingshots, bows, air guns and punkin chunkers shoot out
bullets, rocks, arrows, BBs and pumpkins at the same MEAN SPEED
c, despite the fact that the firing mechanisms of these different
projectile shooters are all entirely different, and speed "c"
holds no special status in emission theory.

There is no spread in the velocity of light in this paper. There
is a spread in the imprecise MEASUREMENTS of the velocity of
light.
If you wish to deny experimental evidence in favour of your bigotry
that is your prerogative, fuckwit. I never dispute empirical data, only
the conclusions that are drawn from it.
Then what you need is experimental evidence more recent than 1935.

A report on measurements by the NBS.

Rowley et al., Opt. and Quantum Elect. 8 (1976), pg 1.
A review article on the set of precision frequency and wavelength
measurements that became the basis for the 1973 value of c. This is
the best single reference for this.

Baird and Whitford, Opt. Comm. 31 (1979), pg 363, pg 367.
Measured c = 299792458.8 ± 0.2 meter/s, with 1.2 meter uncertainty due
to realization of the Kr meter standard used. The fact that the Kr
standard for the meter became the limit on accuracy was a major
reason
for the 1983 redefinition of the meter in terms of the definition of
c
and the definition of the second.

Some of the above are available in the local university library.
Others I can get through interlibrary loan. Do you want to read
them and have your fantasy world shattered? I can get them for
you.
