You need to read my paper again. In EVEY train-embankment experiment there is an observer on the train AND an observer on the embankment.

Again, you clearly have not read the paper.  In experiment #1 I have BOTH observers dropping stones from the roof of the railroad cars while BOTH are stationary.  Both see the same thing.

In experiment #2 I perform the same experiment while the train is moving.  The observers see things very differently.

In experiment #3 I perform the same experiment INSIDE the laboratories on the MOVING train and the STATIONARY embankment.  The observers see what they saw in Experiment #1.

I do that.  You just did not read far enough.

You need to read the entire paper.  The dropped stone experiment is about INERTIA and how different effects are seen outside the labs versus inside the labs.  Later in the paper there are more experiments about light and time dilation.

But the point is not that at all!!! In your figure 3 both observers are dropping
stones TO THE GROUND, ie you are using only one frame of reference

You haven't read the paper.  I'm using TWO BODIES OF REFERENCE.  In figure #3, one BODY OF REFERENCE is on the train and another BODY OF REFERENCE is on the embankment.  They can see each other.  And they can see things happen in a different way.  

In experiment #3 (figure 4) I use "one frame of reference" for each observer inside his laboratory.  Inside the laboratory they cannot see anything else, so there is only "one frame of reference." 

Maybe you need to read Section II. “Reference Body” versus “Frame of Reference.”

Stop being nasty Edward. I have your paper open in my computer and I'm
commenting the parts which I consider are poorly described. Here I'm commenting
about your experiment 2.

It does not matter what name you choose for your "bodies of reference". There is
a train, with an observer on the train roof, throwing stones to the ground and
clearly not to the floor of the train!!

You say "they can see each other". Sure, but you could have used a platform
train (ie no walls) instead of placing the guy on the roof!! This platform, by
the way, takes also care of your experiment 3.

The point is both observers should perform exactly the same experiment, meaning each of them takes a stone and drop the stone from their hands to the floor
(where their feet are located)!!

That way, you can compare what each observer sees as a result of his own
experiment and then compare what each observer say he sees about the other
observer's experiment

That's totally irrelevand. Dr. Ed by "seeing" mean sort of instantaneous 
synchronous activity. But the catch is that "seeing" has to obey causality 
as well, which performs at c under every circumstances. Seeing or not.

I'm not being nasty.  I'm trying to understand what it is that you do not understand.  You ask questions about things I explain very clearly.

What you consider "poorly described" appears to mean that I do not use the words and phrases you use.

They drop stones to the floor in experiment #3.

I wanted the guys on the roof because it is the roof of a laboratory.  So, a flat car would just complicate matters.

They do that in experiment #3!!!!

That is exactly what I do.  You seem to want them done in reverse order.  Why?  

In Experiment #1 BOTH observers are stationary and on the roof of their laboratories.  Their stones fall identically. 

In Experiment #2 one observer is moving while the other is stationary.  They can determine who is moving and who is not by how their stones fall.

In Experiment #3 both observers are in their closed laboratories (frames of reference), and although one is moving and the other is not (just as in experiment #2), they CANNOT tell if ANYONE is moving. 

That is what Relativity is all about.  When they can see each other, they can tell who is moving and who is not.  Inside a closed laboratory they cannot tell who is moving because "the same laws of electrodynamics and optics will be valid for all frames of reference for which the equations of mechanics hold good."

You assert without any proof that I have not read your paper. I repeat I have it
open on one of my screens so I have read it. 

I´m a reviewer of several scientific journals so I know how to read and advice
the authors about being clear in what they write.

For one thing, your drawings while cute are not what a scientific paper
would accept as appropiate. Have you ever seen a physicist with instrument atop
a railroad car (like your figure 1)?

The embankment observer is also located atop another railroad car...why?

Apparently, you are trying to equalize the elevation of OT and OE with respect
to the ground, but that it is not relevant. 

A real physicist would carefully choose the environment for his experiment. He
would use flat, without walls platform cars (that way you can easily detect the
light fronts coming from A and B). An apparatus which can drop the ball or stone
under electric command with sensors to measure the time of flight of the ball
from 2 meters up the train (or embankment) floor to that floor. That way the
embankment observers (note the plural) could also see the ball falling from
their location on the embankment.

All this is just a commentary about your figure 1 (all of the figures share the
same problems).

Why? How the roof of a laboratory has anything to do with the experiments?

You should understand that your experiment 3 is not different from experiment 2,
if you use platform cars. There is nothing peculiar of using your closed
laboratories. You see the symmetry of the movement is related to the geometry of
the problem. If my car moves east to west at 100 km/hr with respect to a sign on
the side of the highway, it is obvious that the sign moves west to east at 100
km/hr with respect to my car driving wheel. This is a fact!! and you do not need
to be in a closed environment to verify this

Why do you want to determine who is moving? Remember the experiment is about how
the fall ball or stone behaves. SR says that for inertial observers they both
will observe the same laws of physics when performing their own experiments,
while the observation of the experiments of the moving observer, will get
different results.

Again that is not the problem. We are trying to stablish the laws governing the
behavior of objects when they are moving inertially with respect to each other.

He has no "instrument."  He has a stone.  I'm just making the experiment as SIMPLE and as EASY TO UNDERSTAND as I can.

Because it makes the situation easy to visualize via an illustration.

It is very relevant if you are measuring how long it takes for a dropped stone to fall a fixed distance to the earth.

In the illustrations that causes problems because the person on the flatcar cannot see over or around the engine and caboose.

The purpose of the experiment is to show how different observers see different things.  Putting both observers on the embankment defeats the purpose of the experiment.

As stated above, being on the roof gives you an unobstructed view - particularly of the lightning flashes.

It is VERY different.  In Experiment #2 the experimenters can see the EFFECTS of movement.  In Experiment #2 they cannot see those effects.

It is NOT A FACT.  It is an absurdity only mathematicians believe.  The whole point of the paper is to show that MOTION IS NOT RECIPROCAL.

I want to determine who is moving to show that ALL MOTION IS NOT RECIPROCAL.  Therefore TIME DILATION IS NOT RECIPROCAL.  Things just APPEAR to work the same way for moving and stationary objects INSIDE A CLOSED LABORATORY.

That IS the problem.  The "laws" say that you will get identical values INSIDE A CLOSED LABORATORY, but the experiments show that TIME moves at a different rate INSIDE those laboratories, which means the time-dependent measured values are actually DIFFERENT.  The laws are the same but the values are different.

You get the speed of light as 299,792,458 meters PER SECOND in both CLOSED Frames of Reference.  But the LENGTH of a second is different, it is longer when you move faster.  Therefore, the speed of light MUST BE different.

Because MANY college textbook state that motion is RECIPROCAL.  And that is what MANY people here argue.

Okay.  In my new paper I say what the person on the train saw was "incorrect," in that it disagreed with the laws of physics.

What M saw was "incorrect," since it was the result of his motion.  It was not what actually happened.

No, I fully agree with it, but MANY college textbooks do not.

Since the assumptions are false, the conclusion is false.  How can a false conclusion be "the only possible conclusion"?

Certainly.  I quote Richard Feynman all the time: "It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong."

Stop right there!

This is what Y and M actually observed:

  Y DID see the two flashes simultaneously.

  M DID see the flash from the front before he saw
    the flash from the back.

It is not an option to claim that it did not actually happen.

No textbook would disagree WHEN THE STATED ASSUMPTIONS ARE MADE.

So you claim that the assumption:
"The speed of light is invariant"
is false without having to refer to
an experiment which show that it is.

You, who pride yourself of your logic, can't fail to
see that it is a fact that the only possible conclusion
from the given premises is as stated above.

GOTCHA!

You agree that the only way you can determine
if the assumption "the speed of light is invariant"
is in accordance with the real world is to make
experiments.

But right above you claimed that the assumption:
"The speed of light is invariant"
is false without having to refer to
an experiment which show that it is.


> I quote Richard Feynman all the time: "It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong."

So let's see what the experiments tell us:

https://paulba.no/paper/Kennedy_Thorndike.pdf
https://paulba.no/paper/Michelson_1913.pdf
https://paulba.no/paper/Babcock_Bergman.pdf
https://paulba.no/paper/Alvager_et_al.pdf
https://paulba.no/paper/Beckmann_Mandics.pdf
https://paulba.no/paper/Filippas_Fox.pdf
https://paulba.no/paper/Brecher.pdf

No experiment has ever falsified the assumption:
  "The speed of light is invariant",
but all the experiments above falsify the assumption:
  "The speed of light is frame dependent".


It doesn't matter how beautiful your theory is,
it doesn't matter how smart you are.
Your claim "the speed of light is frame dependent"
doesn't agree with experiment, so it's wrong.

Or can you to name one experiment which
show that the speed of light is frame dependent!

It may not be an option for you, but it is ESSENTIAL to Relativity.  It is what Relativity is all about.  I see what actually happened, you do not.

Read my paper on Einstein's Second Postulate.  I cite several text books which argue that light will never be measured at c+v or c-v. 

“Second postulate: The speed of light is a constant and will be the same for all observers independent of their motion relative to the light source.” - Michael A. Seeds, Dana Backman, Foundations of Astronomy, Enhanced, Brooks Cole; 11th edition, page 91 (2011)

You're changing the argument, and you're not making much sense.  "The speed of light is invariant" is not an assumption, it is a BELIEF.  And it is incorrect.  The speed of light is VARIABLE.  Pound-Rebka showed that.

The experiments which supposedly show that "the speed of light is invariant" actually just show that the speed of light is 299,792,458 meters PER SECOND regardless of how long a SECOND is in your frame of reference.  If the length of a second is different in a frame of reference, so is the speed of light.

Pound-Rebka showed that the speed of light is variable.  I'll check through your list when I get some time, but I cite Alvager_et_al in my papers, since it does NOT compare frames of references, it measures everything in one frame of reference.  I suspect the others do the same thing.

Pound-Rebka.

Actually, EVERY experiment which confirms time dilation also confirms that the speed of light is frame dependent.  Because the speed of light is the speed PER SECOND, and if time and the length of a second is different in one frame versus another, so MUST BE the speed of light.

So when M DID see the flash from the front before he saw
the flash from the back, what actually happened was
NOT that M saw the flash from the front before he saw
the flash from the back.

Is it really possible that you are so ignorant of elementary
logic that you don't understand that the authors of all the textbooks
mentioned above would answer 'yes' to question #1 above?

There you go again! :-D

You are so inconsistent and ignorant of elementary logic
that you contradict yourself several times in the same posting,
and don't even understand that you are doing just that.

No point in going on.

Quite.

Ed's writings are SO IMMENSELY STUPID, that he couldn't
*possibly* be doing anything but trolling here.
I don't understand what it is that drives people to keep
getting tricked in responding to this submoron.
He will write WHATEVER, as long as he gets response.

I agree that there isn't much point in arguing further.

All the discussions here CONFIRM my observation that no one here can discuss physics without chanting dogma and memorized mathematical equations.  The only argument I get here is that I need to take the courses you took and learn the dogma that you learned so that I can believe as you believe.  

That just makes me more confident in my own findings.

BTW, I checked on those links you provided. NONE dispute what I said about the speed of light being variable.  Plus, I found two other experiments which confirm that the speed of light IS variable: Michelson-Gale and Sagnac.

Kennedy-Thorndike doesn’t even contain the phrase “speed of light.”  It is all about time dilation.

Michelson-1913 simply confirms that the speed of the emitter does not add to the speed of light emitted.  The test takes place with one Frame of Reference.

Babcock-Bergman is performed within one Frame of Reference.

Alvager et al is performed within one Frame of Reference.

Beckman-Mandics is performed within ONE Frame of Reference.

Filippas-Fox seems to be about measurements within only ONE Frame of Reference.

Bretcher simply concludes that the speed of the emitter is not added to the speed of light emitted.  No one disputes that.

If you want to test if the speed of light is variable, you can do it with gravity more easily than with motion.  Pound-Rebka did it.  Light emitted farther from the center of the earth moved faster.  Light emitted closer to the center of the earth traveled slower.  But they didn't compare the lengths of seconds.

The recent Italian experiment did the reverse: http://www.latimes.com/science/sciencenow/la-sci-sn-atomic-clock-gravity-20180212-story.html  They measured time but not the speed of light.

So, if you have standard speed of light measuring equipment atop a mountain and at the bottom of a mountain, they will both measure the same speed of light PER SECOND.  But if you compare the lengths of their seconds, you will find that the atomic clock at the bottom of the mountain used LONGER seconds. 

If they measure the SAME speed of light using seconds of DIFFERENT LENGTHS doesn't that CONFIRM that the speed of light is different when emitted at the top of the mountain versus at the bottom of the mountain?

Two frames. The lab frame and the frame of the neutral pion.

The pion is moving at a velocity of something like 0.2c relative to the 
lab frame. It decays into two gamma rays in opposite directions (in its 
rest frame). If its velocity in the lab frame adds to the speed of light 
in the pion frame, they would have observed gammas in the forward 
direction at speeds up to 1.2c as well as backwards gammas as slow as 
0.8c. They didn't.

(I think they looked at the speeds of forward gammas only so would only 
have seen photons moving at >c, if they existed)

Thanks.  That confirms that the experiment was about the speed of light getting added to the speed of the emitter.  That didn't happen.  It seems to be a duplication of Alvager et al.

But it says nothing about light traveling slower due to time dilation because the only time used was the lab time.
