Don't worry. Though his criticism is well beyond the level of some of my recent referees it is still not at proper level. This does not mean that the concept of a "charged photon" is useful, just that his criticism is merely based on an (incomplete) understanding

<div class="">Hi John W,</div>

<div class="">Below is Stam’s (a PhD researcher in the physics department of the University of Tours) reply to the ResearchGate comment below on my charged photon model of the relativistic electron. I wonder if you agree with his specific criticism or not about
 the proposed charged photon . Is Stam implying that all photon models of the electron would be wrong, or only mine? Thanks. Richard</div>

<div class="">Hello John W and others,</div>
<div class=""><br class="">
<div class="">  I recently posed a question on ResearchGate on my charged photon model — “Can an electron be a charged photon with spin 1/2 hbar?", and am getting some good feedback. You are all welcome to join the discussion there and share your views, criticisms
 and comments.   Here’s my reply to one of the questions:</div>
<div class=""><br class="">
</div>
<div class="">Hello Stam, Thank your for your comments and criticisms. I am not saying that a spin 1 uncharged photon with no rest mass is the same as a spin 1/2 charged electron with rest mass. Clearly these are two different particles. What I am proposing
 is that a hypothetical particle (a charged photon)  may have the essential properties of an ordinary photon -- its speed of light c, its momentum p=h/lambda and its energy E=hf relationships -- and yet have a different spin, charge and rest mass than the ordinary
 photon.  We may differ on what we think are the essential properties of a photon, but I think that the properties of a photon -- the photon's charge, spin and rest mass --which change in a particle transformation such as electron-positron pair production when
 a photon interacts with an atomic nucleus (to conserve linear momentum) may be less essential to the fundamental nature of the photon than the properties of the proposed hypothetical photon that may remain--c, p=h/lambda and E=hf--to form the electron with
 its charge, spin and rest mass.  So I am proposing that it may be useful to think of photons as coming in two varieties that both have the speed of light, energy and momentum properties mentioned above but have different charge, spin and rest mass. In pair
 production, one particle--the photon-- is transformed into two different particles. The spin 1 photon converts to 2 spin 1/2 particles, the uncharged photon is converted into two oppositely charged particles, and the no-rest-mass photon is converted into 2
 particles with rest mass, when the the incoming photon has sufficient energy. But what if the essential properties of the photon -- c, E=hf, and p=h/lambda -- remain unobserved in the electron (yet generate the electron's de Broglie wavelength and the electron's
 quantum wave functions), while the observed properties spin, charge and rest mass of the charged photon--now called an electron -- are different that that of the ordinary photon. Are you saying that this view is not physically meaningful or contradicts any

<br class="">
Coming back to the physics: your analogies of light and material particles, as vibrations of the underlying medium of space and time, stand without starting from some fixed properties. For me this has the added advantage of being far closer to my position -
 that much of what we perceive as reality stems from the underlying nature of space and time. Here, we agree. The point is -why give yourself a fixed limit based on a handful of physical constants set as your starting point (and thus further immutable and incalculable).
 Far better to calculate G in terms of electromagnetism rather than put it in a-priori (which is what Martin and my toy model does - toy or not). As I said before, space and time have to be stiff and strong, not massive and energetic, and it is actually these
 properties that you use to derive your results. Change your limit and the strain in the oscillations goes from the far sub-quantum to something closer to the actual kind of vibration observed in particles. Why not just take it all the way to that which you
 observe? Forget about there being a "maximum possible" for any aspect of space-time.  That is only of any relevance in extrapolating present theories grounded in experiment in the linear regime, far to the point where they become non-linear.<span class="Apple-converted-space"> </span></span></font></span></font></span><span class="" lang="en-US"><font class="" face="Calibri,sans-serif" size="2"><span class="" style="font-size:11pt"><font class="" face="Times New Roman,serif" size="3"><span class="" style="font-size:12pt"><span class="" lang="en-US"><font class="" face="Calibri,sans-serif" size="2"><span class="" style="font-size:11pt"><font class="" face="Times New Roman,serif" size="3"><span class="" style="font-size:12pt">Why

 deadlines (mostly from work, though July 15th is also getting rapidly closer), and feeling the need to put in precious time to ground a discussion I felt was getting out of hand and absorbing too much of all our energies uneccesarily (as GenRel workes just
 fine in explaining it as it is). My apologies. There should be no limit on any of our thinking. In fact, perhaps there should be a follow-up workshop on space, time and gravitation. This is something for discussion in the cafe's in San Diego. My only decent

<span class="" style="font-size:10pt; font-family:Tahoma,sans-serif" lang="EN-GB">Dear people,<br class="">
<br class="">
There is no issue. The speed of light has, as John M and Martin say, a definition. It is the rate of change of space with respect to time. Measured locally. Given this definition it is as John D points out, a tautology that the speed of light is constant as
 measured in all inertial frames. With this definition it then makes no sense to say that something that is constant varies.<br class="">
<br class="">
In accelerated or gravitational frames the situation is different - exactly as John M points out. Indeed, as John D says the speed of light may be viewed as varying  with respect to space wrt any given observer. Equally, it may be viewed as a variation on the
 rate of change of space with respect to some standard. These are reciprocal views of the same thing. You can say I want to keep my space constant and vary velocity (John D), or keep my velocity constant and vary space (John M and Martin). It is worth noting
 though that describing particles as terms of vibrations of the elastic spacetime medium (John D and John M) is inconstistent with keeping space as a fixed grid!<span class="Apple-converted-space"> </span><br class="">
<br class="">
Frankly I do not give a damn ( I have a preference for constant velocity and inconstant space - but then), I can see both (or all three!) at the same time. So what? Provided the effect is very small (say compared to the wavelength of light) it does not matter
 which way you choose to look at it, both are entirely equivalent. General relativity, in general, is written from the John M-Martin perspective).  As Martin says, it works, and it describes the situation perfectly. END of story.<br class="">
<br class="">
Einstein did indeed worry about the limits - but Einstein worried about a lot of things. He was not one-shot one-idea Einstein. He played with ideas -looked at things from different angles. There is no definitive Einstein, and more than there is a definitive
 Williamson, Macken, Duffield or van der Mark. Einstein, though I wish he was still here, is not. Smart though he was, he was not (just like the rest of us) always right. He cannot still argue for himself and we must not stand him up as an ultimate authority
 on everything, but must argue from the merits of every standpoint.<br class="">
<br class="">
Now, this is all a very interesting discussion, but gravitation is a very weak (for me derivative of EM) effect. It only really becomes of any pertinence at all in terms of electromagnetism, the photon or the confinement of the electron at ridiculously, experimentally
 unattainable densities at the Planck scale. Now this is a very interesting discussion- but is distracting me and many of you from the theme of the upcoming conference. We are wasting time on details 20 orders of magnitude outside of where we need to focus
 for the time being. It is, in my view, really for a different conference in a different context at a different time.<span class="Apple-converted-space"> </span><br class="">

 of light.  In one of them the speed of light is constant and in the other the speed of light is not constant.  If the speed of light is measured locally (using a local clock and ruler), then the speed of light is always constant.  If you adopt a single clock

 near a large mass such as the sun, the angle is twice what might be expected from the classical model of the light feeling gravitational acceleration and “falling” as it passed the massive body.  The factor of 2 can be explained two different ways. I will
 not go into the details here because they are covered in chapters 2 and 3 of my book.  However, the key difference between these two choices lies in the handling of the gravitational effect on volume.  The Shapiro experiment showed that the sun has enlarged
 the volume of the surrounding space beyond what would be expected from Euclidian geometry.  If the photon passing through this volume is given credit for having traveled a greater distance, then the effect on the radial coordinate speed of light is different
 than if this effect on space is ignored and all the bending is attributed to a slowing in the coordinate speed of light. </span><span class="" style="" lang="EN-GB"></span></div>

<br class="">
Indeed it is useful to think about the relationship between things. I also agree with John M that gravity and electromagnetism are different aspects of the same thing. As I have said before,  Martin and I developed a toy theory of these a decade or two ago
 which gave the right numbers (with zero extra background mass/energy) but has not developed further than a a few pages in our "appendix" due to lack of time or energy due to the demands of our day jobs.<span class="Apple-converted-space"> </span><br class="">
<br class="">
At the end of the day, replacing one universal constant with another, related one is zero net progress.  In Martin and my 1997 paper we calculated the charge in terms of Planck's constant (or vice versa).   This is one fundamental constant less. The basic idea
 was that the oscillating electric field of the photon became uni-directional due to the folding of the photon path into a double-loop.<br class="">
<br class="">
The hope with the new theory, which incorporates the experimentally observed properties of the four-dimensions of space and time from the outset, is that one can use it to calculate BOTH from first principles. I have tried this within the framework of an emission/absorption
 model in the new classical field theory - and obtained an answer - but it is currently a couple orders of magnitude out.  This is one of the areas I hope to get some help from with within the group - especially those with specialist knowledge of Atomic physics
 - which is where I think the answer lies. Martin and I are anyway onto this - and he is already brushing up on his understanding of Atomic physics (amongst one or two other things!) to help to try to get a handle on this.<br class="">
<br class="">
Just for the record, our toy model calculated big G in terms of 1/(4pi epsilon zero)  ... thus eliminating (in principle)  yet another natural constant altogether: one of the essential assumptions in deriving this was precisely that there was zero net energy
 in the vacuum fluctuations. As is observed.<br class="">
