Essay Abstract

At first glans, this paper would be off-topic, but it would hopefully contribute to physical science as it suggests novel methods for measuring speed of light emitted from moving objects. Speed of light has been measured by various methods and to current knowledge is believed to be constant. These techniques include accurately known measurement methods of the day; e.g. cavity resonator, radio and laser interferometry etc. and are persistently revised. Despite the fact that there exists some controversy regarding the limit of speed of light, but there also methods like FEL (A free-electron laser or FEL, is a type of laser whose lasing medium consists of very-high-speed electrons moving freely through a magnetic structure). Proposed method is based on a conception of measuring the speed of light from a moving frame which according to the principal of special relativity would be a constant quantity in vacuum and is independent of the frame and its relative velocity whether the light is received or emitted. In spite of the theoretical part i.e. relativity and Doppler Effect and the fact that Michelson and Morley experiment doesn’t measure the speed of light directly, this method suggests an applied measurement which needs to be tested. In addition another method based on fringe shift is suggested on a rotating Michelson-Morley platform. In fact the Sagnac effect has already shown a non-null result [1] as it is done on a rotational platform, but this method is somewhat different as one of the mirrors has a slower linear/angular velocity then the other one.

Dear Mr. Shandaei

The speed of light is the limit. The limit we can measure approximately.

It is best to stay exact value by convention.

Dear Koorosh Shahdaei,

Please excuse me for I have no intention of disparaging in any way any part of your essay.

I merely wish to point out that “Everything should be made as simple as possible, but not simpler.” Albert Einstein (1879 - 1955) Physicist & Nobel Laureate.

Only nature could produce a reality so simple, a single cell amoeba could deal with it.

The real Universe must consist only of one unified visible infinite physical surface occurring in one infinite dimension, that am always illuminated by infinite non-surface light.

A more detailed explanation of natural reality can be found in my essay, SCORE ONE FOR SIMPLICITY. I do hope that you will read my essay and perhaps comment on its merit.

Dear Koorosh Shadaei

I invite you and every physicist to read my work “TIME ORIGIN,DEFINITION AND EMPIRICAL MEANING FOR PHYSICISTS, Héctor Daniel Gianni ,I’m not a physicist.

How people interested in “Time” could feel about related things to the subject.

1) Intellectuals interested in Time issues usually have a nice and creative wander for the unknown.

2) They usually enjoy this wander of their searches around it.

3) For millenniums this wander has been shared by a lot of creative people around the world.

4) What if suddenly, something considered quasi impossible to be found or discovered such as “Time” definition and experimental meaning confronts them?

5) Their reaction would be like, something unbelievable,… a kind of disappointment, probably interpreted as a loss of wander…..

6) ….worst than that, if we say that what was found or discovered wasn’t a viable theory, but a proved fact.

7) Then it would become offensive to be part of the millenary problem solution, instead of being a reason for happiness and satisfaction.

8) The reader approach to the news would be paradoxically adverse.

9) Instead, I think it should be a nice welcome to discovery, to be received with opened arms and considered to be read with full attention.

11)Time “existence” is exclusive as a “measuring system”, its physical existence can’t be proved by science, as the “time system” is. Experimentally “time” is “movement”, we can prove that, showing that with clocks we measure “constant and uniform” movement and not “the so called Time”.

12)The original “time manuscript” has 23 pages, my manuscript in this contest has only 9 pages.

I share this brief with people interested in “time” and with physicists who have been in sore need of this issue for the last 50 or 60 years.

Dear Koorosh

You have described your proposal well. Question: having the emitter on a rocket moving at velocity v will introduce Doppler shifts in the wavelength. Why a moving emitter at all?

In my theory of light moving through a discrete universal ether at a maximum speed c Beautiful Universe Theory n pure vacuume, but at slower speeds in gravitational or otherwise energized fields, c would be faster on the Space Station than c measured on Earth. Or would it ? Since clocks would give slower time? Needs thinking out by experts!

Good luck

Dera Vladimir,

Thank you Indeed for your comments, regarding your question about Doppler effect as you mentioned, Doppler effect will happen in our case, but in this method vi are not concerned about it, we only measure the time difference which in our particular case does not involving neither SR nor Doppler effect. The reason I proposing a moving frame, it a novel way of measuring the speed of light from truly moving objects as e.g. MMX doesn't measure speed of light but just measuring fringe shift instead.

Regarding the speed of light on the space station, as I suggested one could calibrate the device as "c" would be measured when the frames are at rest with respect to each other, in this way have vi eliminated what you mentioned about possible energized fields that would impact "c".

I hope, this could clarify your questions more.

Kind Regards


Peter Jackson wrote on Mar. 27, 2017 @ 18:26 GMT

Off topic but worthy of comment. I've studied this issue for some time and agree that better experiments are required as theory and analysis are incorrect, that yours is reasonable set-up, but also that the findings will be analysed as finding precisely 'c'. Are you familiar for instance with Lodges 'spinning glass disc' experiments? and Ruyon Wang's recent advanced 'Sagnac'...

Thank you for your comments, I went though your links, very interesting articles. As you mentioned we can't have any fix reference as the earth and solar system and our galaxy are in complex motion, but I agree that either frame could be considered stationary, so simply we could say detector-frame or light emitting frame to be more precise.

At the detector side there should be inbuilt antennas and no lenses involved then we are not concerned about the refraction. As regards the Doppler effect, that will happen but we are just measuring the time difference as the distance between the detectors is known. Finally we'll get the speed of light with arbitrary precision as we also calibrated our detectors.

I hope I've been able to answer your question.

Best regards


Peter Jackson replied on Mar. 29, 2017 @ 16:47 GMT

That shows flexible thinking so is very good. However my prediction of 'c' remains and matches all findings. Yet doctrine is still wrong. For 'why'; consider this carefully;

ALL matter (not just what we call a 'lense'!) has a surface 'fine structure' of free fermions, familiar as electrons, (or in plasma physics 'surface plasmons' etc.) In Maxwell terms, adding physical reality, this forms the TRANSITION ZONE (TZ) between his 'near' and 'far' fields. An aerial engineer will tell you exactly where it is, varying with wavelength but for light it's around max 1 micron. For a spacecraft or plane it's some metres off the body (it can even often be seen!)

Light will therefore be modulated to the LOCAL rest frame c on arrival at the 'near field' ALL matter and on ALL electron interactions!

So if your receptors are anywhere near each other I fear the result will be 'c' and reinforce poor science. But if they're far apart, then most will likely say their relative range can't be precise enough. It is a big problem, and past experiments have similarly just served to re-inforce doctrine as interpretation is flawed. But do keep working at it!

None the less your low score is rather an insult so adding mine now will help. I hope you may get other constructive responses. I also hope you may read, like and score mine - which I think contains a very important finding also not analysed by most!

Best wishes

Thank you Peter, I agree that the precision of "c" would be a concern at low distances, but the detectors have to be calibrated to be able eliminating such source of possible errors as much as possible. The actual result that is essential here, it is to say that the speed of light would be constant. I will go through your essay.

George Kirakosyan wrote on Mar. 31, 2017 @ 06:15 GMT
Hi dear Koorosh,

Actually you have touching to very important old problem of fundamental physics that however now stands somewhat out of agenda. There was the decision to take this (speed of light) as it is represented in SR and do not to try to change anything here. But some contradictions still continued remains there. That is why your suggestion on new measurement of light's speed can change a lot of things.

But I'm really sceptical that someone will take this opportunity to again put under doubt the declared principles of relativity. The questions however continued to excitate truly thinkers. That is why I decide to support you with my rating.

Please to open my work and check there Ref. [3] where me also put this question and have describe the principle of similar experiment that can causally to explain how we can get the Lorentz transformation and SR without mysteries. But ... who will listen to us?

Be well, my dear!

James Lee Hoover wrote on Apr. 1, 2017 @ 23:03 GMT

I assume that such an experiment has not been tried before -- rocket to ISS. Does the speed of the target, about 17,000 and the speed of the rocket matter in this endeavor? What about rotation speed?

I support out-of-the-box ideas and will rate accordingly. As a science fiction writer, I endeavor to consider unknown factors like quantum entanglement, for example, as a possible factor in speed, something a type 0 civilization does not have the knowledge to consider.

My essay considers speculative ventures to look at dark matter as well. Hope you can check mine out as well.

Thank you for your comments, you touched a very interesting question about the speed of the rocket and I believe that would be a very technical issue, but I think reasonable speed could be a factor of 1000 km/h, but as a matter fact, it is about the null result outcome considering the relative speed of the two frames.

As regards the rotational systems, all of our experiments are performed in a complex rotational system, considering earth, solar system and our galaxy, but in such situations there is a concept called approximate symmetry and approximate linearity which can be applied to this experiment and by this way the experimental data can be treated as it would happen in a linear system by approximation.

I will proceed tor your essay and wish you good luck.

Kind regards

Physics of Descartes, which existed prior to the physics of Newton returned as the New Cartesian Physic and promises to be a theory of everything. To tell you this good news I use «spam».

New Cartesian Physic based on the identity of space and matter. It showed that the formula of mass-energy equivalence comes from the pressure of the Universe, the flow of force which on the corpuscle is equal to the product of Planck's constant to the speed of light.

New Cartesian Physic has great potential for understanding the world. To show it, I ventured to give "materialistic explanations of the paranormal and supernatural" is the title of my essay.
