1. Measure the speed from the spot where the Earth was when the light pulse began. Then, it would be c-v relative to the Earth because the longer distance gives a lower speed in the speed formula.
2. Measure light speed from the spot the Earth reaches when the light beams combine for a possible fringe shift. Then, the speed would be c+v because the shorter distance gives a higher speed in the speed formula.

the origin of the light was, or how the Earth or an observer on the
Earth was moving, the speed of light relative to the observer always
came out to be c.
The Universe sets the rules, and the rule appears to be that an observer always measures the speed of light relative to themselves to be c. The
task for the physicist is to come with a way of describing this
behaviour, which is what Einstein did.
You may not like constancy of the speed of light. You may think it's illogical, or silly, or whatever, but neither you nor anyone else has a choice in the matter. We have to deal with the Universe as it is, not as
we think it should be.

Right. To postulate means to presuppose. The question is, how can it be c within any and every frame of reference?Apparently you never read Einstein's paper.
Einstein postulates the speed of light is c in ONE frame of reference,
which he calls the "stationary" system. "Any ray of light moves in the “stationary” system of co-ordinates with the determined velocity c, whether the ray be emitted by a stationary or by a moving body."
Einstein then goes to show it must be c in all inertial frames. This
part is not a postulate.
Because the speed of light was repeatedly measured as being constant whenever measured

1. Measure the speed from the spot where the Earth was when the light pulse began. Then, it would be c-v relative to the Earth because the longer distance gives a lower speed in the speed formula.
2. Measure light speed from the spot the Earth reaches when the light beams combine for a possible fringe shift. Then, the speed would be c+v because the shorter distance gives a higher speed in the speed formula.
3. Speed is claimed to be c without any explanation of how.
That the speed is c was the starting point for all of this. It was an
experimental result - as far as anyone could tell, it didn't matter what
the origin of the light was, or how the Earth or an observer on the
Earth was moving, the speed of light relative to the observer always
came out to be c.
The Universe sets the rules, and the rule appears to be that an observer
always measures the speed of light relative to themselves to be c. The
task for the physicist is to come with a way of describing this
behaviour, which is what Einstein did.
You may not like constancy of the speed of light. You may think it's
illogical, or silly, or whatever, but neither you nor anyone else has a
choice in the matter. We have to deal with the Universe as it is, not as
we think it should be.
Sylvia.
No, the speed of light always comes out c in a frame with uniform linear motion, as in Galileo's ship. It does not do so when these requirements do not obtain.
This means it obeys Galilean transformations,
not c - v.

which he calls the "stationary" system. "Any ray of light moves in the
“stationary” system of co-ordinates with the determined velocity c,
whether the ray be emitted by a stationary or by a moving body."
Einstein then goes to show it must be c in all inertial frames. This
part is not a postulate.
The answer is that it must be c + v. According to the above quote Einstein said it was c - v.
Can't you read? He explicitly states it is c!
More to the point, why would Einstein have to propose a postulate for that when Galileo already explained that?Because the speed of light was repeatedly measured as being constant
whenever measured, regardless of the motion of the source. In other
words, Galileo's simplification didn't apply to light.
Einstein's quote you give is very familiar and helpful in showing the problems with his ideas. It appears ambiguous.
The question is, does he mean the source of the ray is moving relative to the system?
If so, that would be a different frame of reference.
If he means the source is the system, then it is one frame of reference,
and he is correct because it obeys Galilean transformations.
It was already known that everything maintains its speed within all frames of reference just as it does on "stationary" land as long as it moves with a uniform linear motion. Light does the same.
How can it be c unless calculated using the Galilean transformation C + V?
Did he conjure it?
I wonder if you read the quote? Why do you think that expert said Einstein used c-v?

Einstein's quote you give is very familiar and helpful in showing the problems with his ideas. It appears ambiguous.Say what? It is perfectly clear to me! "Any ray of light moves in the “stationary” system of co-ordinates with the determined velocity c, whether the ray be emitted by a stationary or by a moving body." The observer in the named "stationary" system measures all light as moving
at c, regardless of the motion of the source it was emitted from. Are
there words in his quote that you don't understand? Some of them are
four syllables, is that too many for you?
The question is, does he mean the source of the ray is moving relative to the system?Again, why are you having such difficulty with such a simple concept?
If so, that would be a different frame of reference.???
At that point in the paper there is only ONE frame being discussed, the
one named the "stationary system"
If he means the source is the system, then it is one frame of reference,The source is, as Einstein writes, "a stationary or a moving body."
and he is correct because it obeys Galilean transformations.He didn't state that, plus that is later shown to be wrong.
It was already known that everything maintains its speed within all frames of reference just as it does on "stationary" land as long as it moves with a uniform linear motion. Light does the same.
How can it be c unless calculated using the Galilean transformation C + V?Nobody does that.
Did he conjure it?
He postulated that is what happens in his "stationary" frame. Everything beyond that is derived.
I wonder if you read the quote? Why do you think that expert said Einstein used c-v?What expert? It appears that you made up some sort of c-v garbage and
are trying to blame Einstein for that.

Einstein didn't need relativity. The speed of light is the same across the universe.Yes, I think I know you believe every photon is reabsorbed in interstellar space being re-emitted at c relative to that particle. Then how is there a Doppler shift?
How is the difference between relative and the absolute physics measured? How can science measure their difference? and what is wrong with absolute physics?
Paul... go back to your internet links...
The atom can compete with light absolute speed at a motion black hole.
It shows the atom has absolute speed competing with light.
Why would it be relative?

Steelman of the second postulate: Light speed is independent of the source velocity.

Accepting the longitudinal beam (in the direction of Earth's orbit) averages out to C on a round trip.
If the transverse beam obeys Galilean transformations, its round trip will be at C, MAKING LIGHT SPEED ISOTROPIC.
If it obeys the second postulate, it will be C - V, MAKING IT ANISOTROPIC.

Determined velocity c. Not c-v, not c+v, but c.
Now tell us how the phrase "The introduction of a “luminiferous ether”
will prove to be superfluous" means Einstein really used the ether concept.
1. Measure the speed from the spot where the Earth was when the light pulse began. Then, it would be c-v relative to the Earth because the longer distance gives a lower speed in the speed formula.
2. Measure light speed from the spot the Earth reaches when the light beams combine for a possible fringe shift. Then, the speed would be c+v because the shorter distance gives a higher speed in the speed formula.
3. Speed is claimed to be c without any explanation of how.
That the speed is c was the starting point for all of this. It was an
experimental result - as far as anyone could tell, it didn't matter what >> the origin of the light was, or how the Earth or an observer on the
Earth was moving, the speed of light relative to the observer always
came out to be c.
The Universe sets the rules, and the rule appears to be that an observer >> always measures the speed of light relative to themselves to be c. The
task for the physicist is to come with a way of describing this
behaviour, which is what Einstein did.
You may not like constancy of the speed of light. You may think it's
illogical, or silly, or whatever, but neither you nor anyone else has a >> choice in the matter. We have to deal with the Universe as it is, not as >> we think it should be.
Sylvia.
No, the speed of light always comes out c in a frame with uniform linear motion, as in Galileo's ship. It does not do so when these requirements do not obtain.Well yes, the speed of light is always c in frames with uniform linear

Einstein then goes to show it must be c in all inertial frames. This
part is not a postulate.
The answer is that it must be c + v. According to the above quote Einstein said it was c - v.
Can't you read? He explicitly states it is c!
More to the point, why would Einstein have to propose a postulate for that when Galileo already explained that?Because the speed of light was repeatedly measured as being constant
whenever measured, regardless of the motion of the source. In other
words, Galileo's simplification didn't apply to light.

light was c in this frame. It is you who is trying to decree the speed
as c-v for some unknown reasons.
As to your multiple other replies to my reply, they make about as much
sense as one of Mitch's posts and are unanswerable.
Einstein postulates the speed of light is c in ONE frame of reference,
which he calls the "stationary" system. "Any ray of light moves in the
“stationary” system of co-ordinates with the determined velocity c,
whether the ray be emitted by a stationary or by a moving body." >>>>>> Einstein then goes to show it must be c in all inertial frames. This >>>>>> part is not a postulate.
The answer is that it must be c + v. According to the above quote Einstein said it was c - v.
Can't you read? He explicitly states it is c!
More to the point, why would Einstein have to propose a postulate for that when Galileo already explained that?Because the speed of light was repeatedly measured as being constant >>>>>> whenever measured, regardless of the motion of the source. In other >>>>>> words, Galileo's simplification didn't apply to light.
Einstein's quote you give is very familiar and helpful in showing the problems with his ideas. It appears ambiguous.
The question is, does he mean the source of the ray is moving relative to the system?Again, why are you having such difficulty with such a simple concept? >>>>> If so, that would be a different frame of reference.

He didn't state that, plus that is later shown to be wrong.
It was already known that everything maintains its speed within all frames of reference just as it does on "stationary" land as long as it moves with a uniform linear motion. Light does the same.Nobody does that.
How can it be c unless calculated using the Galilean transformation C + V?
Did he conjure it?
He postulated that is what happens in his "stationary" frame. Everything
beyond that is derived.
What expert? It appears that you made up some sort of c-v garbage and >>>> are trying to blame Einstein for that.
I wonder if you read the quote? Why do you think that expert said Einstein used c-v?
I already explained to you the two meanings possible from his words. It could be that the source is the system (or frame) itself or something moving within the frame.
Which do you think he meant? Both?
said for his "stationary" frame, the speed of light will be measured as
c when emitted from a stationary body, and will be measured as c even if emitted from a moving body.
We cannot start discussing anything involving reflections/mirrors or
even other frames until you understand the simple meaning of the second postulate.

you a mathematician?
That is to say to see things when you are on the other side of the
barrier.
He was right. One of the cruelest faults is the absence of empathy and understanding of others.
The phenomenon has worsened terribly in France since the election of Mr. Macron (doctors are going out of business, no longer working night shifts, Sunday shifts, or Christmas shifts). We only work for profitability. The phenomenon affects everyone. The nurses try to give insulin injections
(even if the patients do not need them as in most cases), refuse serious cases; the pharmacist is looking to sell boxes and thinks about his annual turnover...
The same goes for the physicist, who seeks glory and consecration. For the Usenet poster who wants to show that he has the biggest kiki.
Laurence asks a good question here: What is the basic principle of relativity? How did we come to propose the invariance of c?
If we think about it carefully, we see that the idea came from Henri Poincaré,
but it is true that he does not explain why very well. Later, Albert Einstein, a vulgar copyist who will be shaped into a true genius of humanity, when he was not able to solve a quadratic equation of the type x²-4x+3=0, will try to explain better, but then everything will descend into horror.
Once Einstein wanted to explain why time was relative and light invariant, he himself no longer understood the question he had asked.
This question must be answered.
But it must be done with correction, intelligence, modesty, and humility.
That is to say that, as this great clinician taught, one must first do an internship as a patient, before claiming to be a great genius in world physics, without understanding anything of the theory itself, simply
because while sitting on a chair, we learned the Poincaré-Lorentz transformations by heart without understanding their meaning.
This is not reasonnable.
Doctor Hachel said that the invariance of the speed of light should not be
a direct premise, and that it should not be taught as such.
We must first start from the acceptance of spatial anisochrony in any
frame of reference: this is the dogma.
The rest is only derived from the principle.
If phonic transactions are instantaneous for the observer,
but that something plays the role of an artifact in our perceptions of it, we must then start from the associated principle that the speed of light
is infinite in one sense and that it is equal, by nature, to 0.5c in the 'other.
A logic comes immediately: if the speed of light is infinite, for a direct observer, it is necessarily so in all frames of reference. And if an observer sees a light ray fleeing, he will obviously see it fleeing at the same speed in all frames of reference.
We come to all the neutral observers of all the frames of reference who observe a phonic transaction in a transversal (or neutral) way.
It goes without saying, directly, that the transverse observable speed of light will be equal to c.
But the primum movens is not the effect, but the principle.
And the principle is universal anisochrony, and the fact that if we can easily match the chronotropy of two or a thousand inertial watches (they will all beat indefinitely at the same speed), they will however never
mark the same time. .
The notion of an absolute universal present does not exist.
I thank you for your attention and perhaps for your superhuman effort to understand what my celestial greatness teaches.
It's not won in advance.
R.H.
It is clear to everyone that the speed of light is a universal constant of nature.
It is also clear that light speed is isotropic in an IRF.
That is clearly explained by Galileo.

I appreciate your acknowledgment of the ambiguity in Einstein's quote, which Volney failed to recognize.
However, I would like to clarify that in the experiments cited by Roberts, I am referring
to those in which the source is not in motion within the IRF.
It is reassuring to have someone who acknowledges that the Galilean transformations
apply in such cases, despite Jan, Sylvia, and Volney's denial of this fact.
Do you understand that this requires light to share the velocity of the source, and is not
independent of it?

Shoddy thinking. You haven't specified the source of the light. Is it stationary in
your IRF, or is it moving? If it's NOT moving, then there's no problem, but if it's
moving then the Galilean transform gives an incorrect prediction.

A velocity independent of that of the source, of course, is the opposite of Galileo and requires c - v.
You must choose one or another
and not pull rabbits out of hats.
It is not valid for a wave. For example, a sound wave would not cause a Doppler shift
in an ambulance siren if it did not share the velocity of the source per Galileo.
I am not an ether theorist, and shared velocity is a characteristic of emission theory.
You are unaware of your reliance on Galileo.
You correctly understand you can treat an IRF as stationary, yet fail to comprehend that it
requires Galilean transformations.
The mirror moves away from the source, requiring the light to move further.
You must perform the calculations. It is required.
The velocity is not invented out of thin air.
The velocity is only shared when it assumes Galileo.
At the bottom is an ambiguity in how relativists use the phrase "velocity independent
of the source."
If it shares the velocity, it is c + v; if not, it is c - v.
Correctly speaking, the phrase ("independent") should be applied to c - v because it comes
from the ether interpretation in which it was supposed by Michelson that light did not share
the velocity of the source (c - v).

You are very confused. SR unequivocally predicts that light speed (in vacuum) will be isotropic relative to any (locally) inertial frame.
There is no need to invoke any "subtractive velocity formula" (whatever
that is).
Part of your problem is using PARAPHRASES of Einstein's postulate. His actual second postulate is:
Any ray of light moves in the “stationary” system of
co-ordinates with the determined velocity c, whether
the ray be emitted by a stationary or by a moving body.
N.B. "stationary" is just a label, and here refers to
an ARBITRARY inertial frame.
This is talking about the one-way speed of light in vacuum. It CLEARLY implies isotropy of that speed.
I remark that since 1905 we have learned to derive the equations of SR without this postulate -- that permits the separation of the geometrical aspects of SR from electrodynamics.

Steelman of the second postulate: Light speed is independent of the source velocity.
Assuming no ether.
Accepting the longitudinal beam (in the direction of Earth's orbit) averages out to C on a round trip.
If the transverse beam obeys Galilean transformations, its round trip will be at C, MAKING LIGHT SPEED ISOTROPIC.
If it obeys the second postulate, it will be C - V, MAKING IT ANISOTROPIC.
"This is what one (starting with Einstein) calls the “addition of velocities”, save that here it is the “subtraction”. This “addition” relationship, is here called s. No such object or relationship exists that mathematically can be called
Galilean transform gives a positive additive velocity, yet the transverse beam covers a hypotenuse's lengthened path, so the increased speed matches the increased length.
Relativity uses a negative additive velocity formula (see above quote) to give a slower speed over the lengthened path.

or if you prefer 1 GeV/GeV,
In the SI the second -is- the unit of length, so also of distance. (up to a trivial numerical constant kept for backward compatibility)JanWell, speed is distance / time not time over time and c= 300,000 km/sec.
Yes, someone already said that in 'Hundert Autoren Gegen Einstein',JanTime is not length in the real world.
so it must be true.
You are a pseudoscientific nitwit.Last warning: if you can't behave in a civilised way
I'll stop replying to you altogether.
And for the amusement of others: it is always fun
to see how this trivial matter of natural units
serves as a touchstone to separate those who are capable of understanding physics from the nutters, crackpots,
and generally incompetent.
Real physicists take it in their stride: just another
and often very convenient system of units to calculate things with.
Real physicists also understand that -physical results-
cannot depend on the choice of the unit system.
Just use the one that is most convenient for the purpose at hand.
But somehow it always causes the nutters to start foaming at the mouth,
JanStraw man reference to Hundred Authors.
You are a pseudoscientific nitwit.
Relativties confusing of time and length separate the scientists from the fools.
Time is not a length. It is a relationship."Real knowledge is to know the extent of one's ignorance."

Time is not length in the real world. You are a pseudoscientific nitwit.
Find out what a "light year" is!!!!
It is distance/speed= time= a relationship or ratio not a distance.
Why do you insist on making up garbage and pretending that it's true?
You miss the point as usual.
You claimed "[a light year] is distance/speed= time= a relationship or
ratio not a distance." Which is incorrect. A light year is strictly a distance, the distance light travels in a year. Just like a mile is
strictly a distance.
Do you want to quibble what a year is? 365 days? What about leap years?
Or 365.2422 days (x 86400 seconds/day), our best measurement?
