Of course.  Lorentz has written such a theory a
long time ago.

They can get result whatever they want. 
It's just that your insane ideology will 
announce them unproper when they don't 
match it.
That's all, lady.

Of course, because there is no ether flying through
Michelson's laboratory at any time of the year. In
the original experiment the medium was the air in
their laboratory, and although the experiment was
repeated with the apparatus inside a vacuum chamber,
this of course made no difference to the result, because
the medium was the matter which remained within the
vacuum chamber, which of course defines the same frame
of reference as the vacuum chamber itself.

Yes.

The "overlapping" part of the journey is a bit tricky,
because the local medium can not possible be stationary
with respect to both observers. However, providing you
carefully define exactly what your experimental setup
is, it can be done. In fact it isn't really that tricky,
because the speed of light for both observers is simply:
                c(medium) + v(medium)
where v(medium) is the velocity of the medium relative
to the observer.

Yes indeed Sylvia. That's the thing about the "speed" of
ANYTHING. It DOES indeed depend on who is measuring it eh!

It really is not difficult Sylvia. Light and sound both
obey the "wave equation", as you know, and sound travels
relative to the local medium it is traveling through,
and so too does light, only much faster eh!

So what about light travelling through interplanetary space? That's not 
completely devoid of matter, so your model would imply that it travels 
at the speed of light relative to that matter which will not be the same 
as its speed relative to us.

Yet if its speed relative to us is not the speed of light, our 
calculations of where we should expect to see the other planets will be 
wrong, because they assume a specific transit time. That effect is 
noticeably absent. Your model needs to explain that absence.

Your model is also going to run into problems with extremely high 
vacuums, where the matter consists of particles moving at speed in 
random directions. How is light to determine what its speed should be 
relative to?

Correct, but because the speed of light is very much greater
than the speed of the interplanetary medium the difference
will not be very great.

The velocity of light relative to us at any point on light's journey to
us will be the vector addition of the velocity of light (near enough c),
and the velocity of the medium. So to calculate the effect of the
medium you would need to know the magnitude and direction of the 
velocity of the medium relative to Earth at all points. The calculation
would be a bit tricky, but if you think you have data which shows this 
can not be right, do post a reference Sylvia, and i will gladly take a 
look at it.

Like most pre-20th century physics theories, Maxwell's e-m theory is a
macroscopic theory, which implies that the medium is treated as
continuous. The theory does of course break down at the atomic scale,
but for most considerations the Solar system is well big enough for the
macroscopic approximation to be applied without significant loss of
accuracy eh!

As you know, Maxwell already explained why that is not true.  The medium of light propagation is not air or any other ordinary matter, it is (according to Maxwell) the luminiferous ether, which is not dragged along appreciably by ordinary material (like air) with index of refraction very close to 1.  That's why Fizeau showed no appreciable effect when air is used instead of water, and that's why Maxwell predicted a second-order fringe shift in an experiment like the one Michelson later performed.

Of course, it is true that light propagates at speed c/n in terms of the inertial coordinates in which the ordinary material (if any) through which it is passing is at rest, but this is perfectly consistent with special relativity.

Many empirical observations show that the total convection theory that you espouse is false.  That's why it was abandoned over a century ago.  To give just one example, if the earth totally drags the medium of light propagation (as you need for Michelson), it obviously does not drag the medium out to the distant stars, so starlight would arrive along rays in the medium of interstellar space, and then as they approach the earth they would need to curve into the local convection field being dragged by the earth.  This is inconsistent with the observed aberration of starlight.  Stokes tried to salvage the convection idea by making a weird assumption about boundary conditions, but Lorentz showed (back in the 1800s) that Stokes' assumption entails a contradiction.

As always, you are mistaken and confused.  Among Maxwell's more important contributions to science was the kinetic theory of gases, in which gas was recognized and treated as consisting of small particles moving ballistically in empty space.  As noted above, Maxwell explained that the medium of light propagation was manifestly *not* ordinary matter, it was some underlying ether, whose properties were not known.  He considered whether the ether itself might also be particulate, although when working on electromagnetism he tended to assume it was continuous, homogeneous, isotropic, and nearly stationary, definitely *not* dragged along significantly by ordinary matter like air or even the earth.  Hence his predicted second-order effect for Michelson.

> They would also both get the same number for the speed of sound...

No they would be quite different for sound, but nearly identical for light (in regions where the index of refraction is close to 1).

Letting u denote the speed of sound in the inertial coordinates of the acoustic medium, the speed in terms of inertial coordinates in which the medium is moving at speed v is (u+v)/(1+uv/c^2), which of course is virtually u+v for ordinary acoustic waves.  Hence the speeds are quite different in terms of the two inertial coordinate systems.

In contrast, if u = c/n is the speed of a pulse of light in inertial coordinates of a medium with index of refraction n, the speed of the pulse in terms of inertial coordinates in which the medium is moving with speed v is (just as in the case of sound) (u+v)/(1+uv/c^2), which is just c/n times the factor (1+nv/c)/(1+v/(nc)).

As an example, air has n = 1.0003 so the speed of a pulse of light is 0.9997c in the inertial coordinates of the air, but in terms of inertial coordinates moving at speed v = c/2 the speed of that pulse of light is 0.9999c, so approaching the source at half the speed of light makes almost no difference in terms of the speed.

So, although sound and light obey exactly the same equation, the result is radically different because of the great difference in their speeds compared with c.

Bull shit. "Air" was Maxwell's primary example of a medium for his e-m

ordinary matter eh!

More bull shit. Maxwell never mentions ether or aether in his long

I don't think Fizeau used air, but give a reference, if you not lying again.

You are just full of bull shit Henry. There is no difficulty in
fully explaining stellar aberration when assuming that the light
travels relative to the matter it travels through.

More bull shit. In the scenario given by Sylvia,

get the same number for the speed of sound and light.

That's a gross misreading, because Maxwell used the word "medium" in that treatise in two different senses.  In some places he used the word to refer to an ordinary material substance, but in other places he used the word to refer to the "luminiferous medium", for which he later adopted the word aether to distinguish it from ordinary material media.  Indeed he wrote the long article on Ether for the Encyclopedia Britannica, in which he explains that this is the luminiferous medium that formed the basis of his electromagnetic theory.  As he said, the entire treatise was intended to form a mental representation of the constitution and workings of that underlying luminiferous medium.

"In another experiment Fizeau has observed that the propagation of light in a stream of water... and that the phenomenon does not occur when air is substituted for water".  James Clerk Maxwell

Maxwell routinely noted that the propagation of light in air is essentially the same as in vacuum:  "According to our result, the ratio of electromagnetic to electrostatic units should be equal to the velocity of light in air or vacuum".  James Clerk Maxwell.

What is wrong with you?  I gave you all these quotes and references before.  Are you undergoing shock therapy or something?  Are memories being wiped from your brain?  Or are the facts just too painful for you to absorb?  Your behavior is really bizarre.

Well, the difficulties of accounting for stellar aberration (and other effects) in a fully dragged theory of the kind you espouse are well known.  This is precisely why such theories were discarded.  I explained the problem in the text you quoted, and you didn't respond.

> That is certainly NOT what he says in his famous Treatise on Electricity

He didn't address the subject there.  He addressed the subject years later in his treatise on the aether.  So, not only are you appeals to ancient authority irrelevant, your authorities actually contradict everything you say.

The speeds in terms of two different systems of inertial coordinates, one stationary with the source and one approaching the source at speed v, will differ by almost exactly v for sound, but will differ by almost nothing for light (in air, for example), as explained.

The solar wind is the primary medium and is moving outward from the
sun at about 500 to 700 km/sec at earth orbit.  That amounts to 0.2%
of c and would be VERY noticeable.  It doesn't affect the speed of
light noticeably and refutes your assertion.

The solar medium spirals outward from the sun,and its effect
will depend on both speed and direction, and exactly what
measurement is being made. Your .2% figure is just made up
nonsense eh!

Are you listening to your schizophrenic voices that tell you that?
It certainly is pure fabrication.

"Although it is always directed away from the Sun, it changes speed"

More bull plop.  Everyone except crackpots know how to measure velocity.

> Your .2% figure is just made up nonsense eh!

"the slow solar wind is observed to have a velocity of 300–500 km/s, ...
the fast solar wind has a typical velocity of 750 km/s"

https://en.wikipedia.org/wiki/Solar_wind#Fast_and_slow_solar_wind

A value of 600 km/sec is 600/3x10^5 = 0.002 = 0.2%, dishonest creature.

You seem to be arguing in favour of a kind of aether dragging model, 
except in your model, matter substitutes for the aether, no matter how

Such a model faces the same obstacles as the aether dragging model did. 
It was impossible to make it fit the experimental evidence without 
introducing ever more implausible assumptions about it.

For your model to be viable, you would have to address all the issues 
that faced physicists in the pre-relativity era. In the end, they were 
not successful.

Exactly so Sylvia. One could say that it is equivalent
to a fully dragged ether model, but i would much rather we
not do that, as, from experience, the introduction of the
notion of "ether" only serves to confuse. The medium, for
any wave, be it water, sound, or light, is the "matter"
which it is passing through.

If we limit our discussion to inertial coordinate systems,
like Einstein did in his SR, i do not agree that any
additional assumptions are required. Your link, while
entirely appropriate and relevant, actually illustrates
how the notion of "ether" only served to confuse. I would
happily explain the fallacies  in any of those arguments
given in your Wikipedia article, but really do not have
time to take that lot on right now eh!

Let's consider the situation being examined by the Fizeau experiment.

If light travels through stationary water at some speed v, and then the 
water itself is moved at speed w relative to some observer, what does 
your model say about the speed that the light will travel relative to 
that observer.

v +/- w?

Something else?

Sorry for the delay responding, been away on the boat.

If you put the water in a tank on a train, then for sure
it is easy (for me :) ) to show that the speed of light
in the water relative to observer on the embankment
  = v +/- w
where v is the speed of the train, and w = c/n(water)

Now this was not of course how Fizeau determined the
speed of light in moving water, and i have two quite
separate objections to Fizeau's method. Firstly he
relies on reversing the water flow without changing
the optical path by a fraction on the wavelength of
light, and i am very doubtful that he could do that,
or know that he had, even if he could.

Even more important, because the water circulates,
i.e. changes direction, the velocity of water is
not constant, and therefore the water does not
constitute an inertial frame of reference.

One of the few things Einstein got right, in my
opinion, was to start by limiting his considerations
to inertial ,constant velocity, systems, as Einstein
did  his SR.

So is there ANY experiment (using inertial systems)
which proves that light does not travel with a velocity
appropriate to, and relative to, the matter it is
traveling through, Sylvia?

Sorry Paul, i posted in haste, without studying your links,
and now that i do, i do see that they do indeed attempt to
answer my criticisms of Fizeau.

Your first link concludes with the somewhat mysterious
statement "We now see that the ether is entirely unaffected
by the motion of the matter which it permeates", which seems
a very strange conclusion for anyone to come to, to me. Can
you explain ?

Henry has claimed that Fizeau has been repeated with air
as the moving medium. Can you confirm that, and do you have
any link for that?

Thanks again.

Measurements have been made in flowing air, rotating glass disks, fused
silica, etc. using light of varying wavelengths.

Zeeman's measurements using different colors of light. He used -very- 
large bore tubes to eliminate uncertainty about the flow rate, requiring
special permission to tap directly into Amsterdam's main water line. Being
a Nobel prize-winner helped, I imagine.

No.
Michelson's thoughts about the "luminiferous ether" are
quite irrelevant.

The important point is what he measured, not how he in 1886
interpreted his measurements.

He measured that the speed of light in moving water was:
   c/n ± x⋅v  where x = 0.437 ± 0.02  when n = 1.334

This shows that the speed c/n transforms according to
the Lorentz transform, and not according to the Galilean
transform.

That is in the very same paper:
https://paulba.no/paper/Fizeau_by_Michelson.pdf
see page 385

The x was measured to be less than the measuring precision 0.02.
The Lorentz transform predicts x = 0.0036 (n = 1.0018)
The Galilean transform predicts x = 1

See the posting from from Prokaryotic Caspase Homolog
He has references to several measurements in different media.

Fizeau's experiment and its numerous repetitions show
that the speed of light in a medium transforms according to
the Lorentz transform, not according to the Galilean transform.
