Vladimir,

You wrote: " When objecting to the constancy of the speed of light I should always add that I believe there is a *maximum* speed of light c in a vacuum free of gravity and e/m fields, but that light slows down in denser media such as a gravitational field, air, water or glass etc."

The problem is different. See this:

Roger Barlow, Professor of Particle Physics: "The Doppler effect - changes in frequencies when sources or observers are in motion - is familiar to anyone who has stood at the roadside and watched (and listened) to the cars go by. It applies to all types of wave, not just sound. (...) Moving Observer. Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/(lambda) waves pass a fixed point. A moving point adds another vt/(lambda). So f'=(c+v)/(lambda)."

"In time t, ct/(lambda) waves pass a fixed point." That is, the speed of the waves relative to the fixed observer is c.

"A moving point adds another vt/(lambda)." That is, the speed of the waves relative to the moving observer becomes c'=c+v.

Is c'=c+v correct, Vladimir?

If you do not understand why your rating dropped down. As I found ratings in the contest are calculated in the next way. Suppose your rating is [math]R_1 [/math] and [math]N_1 [/math] was the quantity of people which gave you ratings. Then you have [math]S_1=R_1 N_1 [/math] of points. After it anyone give you [math]dS [/math] of points so you have [math]S_2=S_1+ dS [/math] of points and [math]N_2=N_1+1 [/math] is the common quantity of the people which gave you ratings. At the same time you will have [math]S_2=R_2 N_2 [/math] of points. From here, if you want to be R2 > R1 there must be: [math]S_2/ N_2>S_1/ N_1 [/math] or [math] (S_1+ dS) / (N_1+1) >S_1/ N_1 [/math] or [math] dS >S_1/ N_1 =R_1[/math] In other words if you want to increase rating of anyone you must give him more points [math]dS [/math] then the participant`s rating [math]R_1 [/math] was at the moment you rated him. From here it is seen that in the contest are special rules for ratings. And from here there are misunderstanding of some participants what is happened with their ratings. Moreover since community ratings are hided some participants do not sure how increase ratings of others and gives them maximum 10 points. But in the case the scale from 1 to 10 of points do not work, and some essays are overestimated and some essays are drop down. In my opinion it is a bad problem with this Contest rating process. I hope the FQXI community will change the rating process.

    Thank you Vladimir,

    I did mean that only people who still believes that GR is a kind of final theory will be troubled by the new research. However, the theory itself does not care!

    I have downloaded the Beautiful Universe theory figure to my desktop.

    Recall that the force is computed from a field potential. Therefore the density of energy varies locally (in the special case when this density is uniform, the force is zero).

    Regards

    Pentacho

    I am sorry but please excuse me from engaging on these SR questions with you here. I have certain ideas and they may be right or wrong, but they need more study.

    Good luck to you

    Vladimir

    Thank you Sergey, I read and rated your essy with a comment on your page. I agree with you, as many have noted, that the current rating system is badly flawed. I am sure the administrators realize it by now after all the complaints.

    Best wishes,

    Vladimir

    Thanks Juan

    The Beautiful Universe theory needs a lot of work, especially in converting the ideas to quantitative formulations. And there are a lot of particles to be assembled from the dipole nodes, like spherical lego sculptures.

    Yes the gradient of the potential is what creates force - but in BU the local density is not simply a scalar, but it has vector properties. The angle between adjacent node's magnetic axes defines gravity. I really need to illustrate and analyze this in better ways.

    Vladimir

    Thanks Stephen

    Change of velocity is defined locally as a change of the index of refraction n= c/v where v is the local speed of light. These ideas were explored briefly by Thomas Young and later Eddington, and are a basic concept in my Beautiful Universe Theory . Speed of light in Maxwell's equations is related to the ratio of the permittivity and permeability. You say the formulation is more complex than that in the presence of gravitation...but what if (n) is linearly related to the local dielectric density of the rotating dipole- nodes, in units of (h)? Wouldn't that then relate angular momentum in (h) to permittivity to permeability to (V) ? You have a more systematic mathematical mind and training it will be nice if the relations are linear as I anticipate they are. Anyway this is a rather unfocused off the cuff reply, and it obviously needs more analysis. In my studies of streamline diffraction in the 1980's I speculate that the bending of the diffracted streamlines around the obstacle are exactly akin to the bending of light in (GR)= ie the speed slows down with curvature and deceleration.

    I strongly feel that this needs to to come out of whatever simple final theory of gravity proves correct both in the very near atomic and far fields.

    By the way read Juan Miguel Marín's essay here - he relates density to Riemann geometry.

    Best wishes,

    Vladimir

    Yes, just as you say. I'm been focusing on developing the mathematics at the fundamental level, i.e., the microscopic level of elementary particles. But as you step up a level or two to the macroscopic realm you may determine the permittivity and permeability on the basis of the volume density of each particle species (just as you say). From there you can fairly easily determine the effective propagation speed of EM waves.

    I'll look at Juan Miguel Marín's essay. It sounds logical that density relates to Riemann geometry, just as the dielectric tensors used to determine values in the constitutive relations are microscopic homomorphisms of the tensors used in Minkowski's electrodynamics for macroscopic calculations. Obviously getting things right in the microscopic domain has large advantages to only getting something that sort of works in the macroscopic domain.

    Vladimir,

    The fact that the speed of light varies with phi, the gravitational potential, cannot be denied. In 1911 Einstein adopted the equation c'=c(1+phi/c^2) given by Newton's emission theory of light, then in the final version of general relativity the speed of light became even more variable: c'=c(1+2phi/c^2).

    Yet Einsteinians never discuss this for a simple reason: if photons slow down as they leave the gravitational field of a star, then they come here on earth at a decreased speed c' lower than c. Einsteinians exercise themselves in crimestop in such cases:

    George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity."

      Dear Vladimir,

      I have just put up a link to a web site giving further explanation of the RICP explanatory framework on my essay thread. I really appreciated your response to my essay and thought on the basis of that you might be interested. So here is a link to it for your convenience foundations of the new building 'prototype' you talked about?

      I do need to add further links to that site, giving more information and relevant scientific papers and need to do something more with the recent discussions of truth.It is, I hope, still a useful introduction.

      Kind regards Georgina

        That was me -Georgina : )

        Pentacho

        Thanks for the explanation - I have to study more how to formulate my views on these issues.

        Vladimir

        Dear Georgina -

        Thanks for sending me the link to your cool website. Not only the cool bluish background, but it is refreshingly simple and focused, and your great graphic has pride of place in it.

        If you ever re-do the graphic perhaps the vertical texts can be made a bit more legible with more space between words, font size etc.

        Please remind me of further developments in your interesting ideas. I like your term "unitemporal now" it describes well my own conception of an essentially timeless universe but where one can compare various states in the causal sequence as as episodes in 'time'.

        Best wishes from Vladimir

        Dear Vladimir,

        I find interesting your beautiful universe paper, as well as this essay, both original and well illustrated. I also appreciate that you used as inspiration some of Kenneth Snelson's ideas.

        Good luck,

        Cristi Stoica

          Vladimir

          Beautiful essay, and so many fixes. It IS broke and does need rebuilding, from the ground up.

          Matt

          Thank you Cristinel for reading my papers. As you see the ideas therin need a lot of development so I am glad a number of experts in various fields of physics have read them. Indeed I was very interested in Snelson's beautiful experiments with rotating circular magnets - it demonstrated how matter can retain its structure even while each element in it is rotating at a certain spin. I still have to study his electronic models which are beautifully conceived as well.

          Vladimir

          Thank you Matt its been fun writing this essay. Good luck to you.

          Vladimir

          On Lawrence B. Crowell's page, where the above link leads, I answered:

          "Lawrence it give me no joy that the rating system is flawed and that serious competent work by you is rated less than the sort of papers, mine included, that you criticize.

          Having said that, I agree with Edwin's responses about your attitude. In a remark above you say that "The solution might in part be under our noses.". But as long as mainstream physicists turn up their noses on anything new however simplistic or amateurishly presented, and stick to ossified concepts enshrined in century-old textbooks, quibbling only on details and footnotes, physics cannot possibly advance. There are many journals, conferences, textbooks and universities open to highly qualified physicists like Lawrence.

          It will be nice if he leaves us this fqxi as a forum to express our hopes and dreams and half-cooked ideas for a more coherent less disjointed physics. Ideally the professionals might one day sniff out a good idea or two here that they can develop to their heart's content. Respectfully and with best wishes,

          Vladimir"

          Stephen

          I look forward to the mathematics you are developing for the microscopic level. However it is not mainly the density of particles that I am interested in but rather a way to formulate the very basic interactions in the lattice of my Beautiful Universe theory. Since the vacuum nodes are the same as those that make up radiation and matter only one sort of basic interaction is needed - summated of course in the case of complex particles.

          The basic idea is that each node has spin in units of (h) and that this momentum is transmitted to the next node at a velocity proportional to the recepient node rotation (also in units of h). Since a node is also assumed to be a dielectric and its rotation creates magnetic moment and an electric field, this would be the basis for computing the permittivity and permeability. I guess I am repeating myself - but that is what needs to be done and I need to think it out some more. Thanks for any input along these lines.

          Best wishes, Vladimir
