The suggestion that nothing can move faster than c is, as John Hodge has commented, apparently contradicted by the artifact we view as “entanglement”.

I am firmly of the opinion that observation and experimental fact are reality. The interpretations of those realities can vary between different interpreters. If one theory or explanation for them does not match experiment or observation, it is the theory or interpretation that is wrong, not the observation or experiment. The only exception to that rule is when it is shown that there were errors in the experiment or observation.

These include Einstein’s special and general theories of relativity and Dirac’s prediction of a positive electron. That they were subsequently verified by experiment is a credit to this mathematicians. However that does not mean the mathematics caused them. They had a physical reason to happen, a physical cause. As we now know, Dirac’s positron arises out of interactions involving high energy photons with other photons or nuclei. A physical principle causes an effect that was matched with mathematics. That doesn’t necessarily mean that it is totally understood. It is a strong suggestion that Dirac was on the right track and following scientists have a reasonably strong foundation for expanding on that work.<o:p></o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'> <o:p></o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'>Let us now look at SR and GR. Einstein worked out the corrections for SR based upon the constancy of the speed of light for all observers. All his predictions have since been verified. I accept that the constancy of the speed of light is the cause of the effect and that Einstein’s calculations were an accurate reflection of that reality. That does not mean that I accept that SR is a “core feature of our universe” which has no other reason. To the contrary, I have written a paper concerning the proposal the an electron is composed of a photon of the appropriate energy that makes two revolutions within its wavelength. It is similar to a structure proposed by Williamson and van der Mark when they suggested an electron was a “toroidal photon”. Others have come up with similar models.<o:p></o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'><o:p> </o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'>An electron composed of a photon rotating at the speed of light, c, has some interesting properties. As fas as the constant speed of light is concerned, to move such a particle must orient its axis in its direction of travel. The rotating photon spirals its way through space. When it does that, the inability of an electromagnetic oscillation to travel other than at c means that it is automatically subject to the SR corrections of mass, length and time with velocity. Mathematically those corrections are little more than Pythagoras theorem applied to any particle composed of a rotating photon. <o:p></o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'><o:p> </o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'>Regarding your comment:- "</span><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:navy'>this implies to me that you see no need for any (deeper) causal explanation for observations of SR; this in turn tells me that your “<i>physical principles supported by mathematics</i>” refers to the principles cited as <i>postulates</i> of SR, rather than those that provide <i>causation</i> for the observed phenomena leading to those postulates.

I am quite content to suggest that the rotating (toroidal) photon structure of matter is both the physical principle and cause behind the SR corrections. As such it lends great credence to the theory’s use of the word “relativity” in its title. Everything is observed relative to the observer. There is no fixed point against which all observations must be referenced. I suggest that what I have called the physical principle behind SR are the rotating (toroidal) photon structure of all matter and the constancy of the speed of light to all observers. I see no reason for any other explanation. Some have suggested my theory is incorrect because of the need to apply the SR correction to the rotating or toroidal photon structure. I do not accept that hypothesis. Instead I maintain that structure IS the cause of SR corrections. It is not subject to them. I would suggest that structure is your “Why is it so?” for SR.<o:p></o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'><o:p> </o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'>While talking about relativity I will raise a couple of issues concerning GR. Again the choice of relativity in the title implies everything is relative to the position of the observer. Einstein used the physical principles of the constancy of the speed of light to all observers and that mass distorts space-time, giving rise to gravity. They are physical principles. That his mathematics eludes most (mathematical) physicists does not make his work wrong. What does make GR wrong is the insistence of some mathematicians on extending the equations he developed beyond the region of their applicability. His field equations work well for weak gravitational fields. They break down as mass increases. I won’t go into that detail here. It can be worked out from Newton’s Mathematical Principles of Natural Philosophy, Volume 1, Proposition 45 and the observation of the then unexplained precession of Mercury’s orbit. When that is understood and the mathematics expanded it brings the only conclusion possible. Mass does indeed distort space-time. Space-time distortion ds is composed of a space distortion dr and time distortion dt. It should go without saying that dr = z (gravitational redshift of photons) and dt = 1/z. It is not difficult to either derive or prove.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'><o:p> </o:p></span></p></div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'>I add that to Einstein’s SR because most people who criticize his work do so because they don’t understand either the physical principle behind them and/or the mathematics associated with them. IMHO they are soundly based. What is not soundly based is the extensions of GR into high mass regions and the prediction of events like black holes which “Have no physical principle, being instead an extension of Einstein’ field equations” - author unknown but is the general belief of all GR and black hole specialists. That is something I suggest has no causality. As far as their detection is concerned, astronomers have detected massive objects. It is theoreticians who claim they are black holes. <o:p></o:p></span></p><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'>I admit that, word for word, you did not mis quote me.

If you have a better physical reason for the SR corrections I would be happy to browse it. IMHO, I think you are being a little pedantic over the choice of words such as “crumpled” or “split” or “required” for a single gamma. This discussion began with my physical and mathematical representation of photons.

It’s in response to your “<i>requires</i>” that I cited two clear instances where an interaction (of a linear photon) with matter was <i>not</i> required to produce e+/e- pairs: Landau & Lifshitz’s finding (Sov. Phys 1934, vol. 6, P.244ff) that pair production in collider experiments is characterised by prior production of high-energy photons that then collide to form particle-antiparticle pairs; The Breit-Wheeler Process, actualised as a multi-photon event at SLAC in 1997. In neither of these does matter interact with a photon to produce those pairs.</span><o:p></o:p></p><p class=MsoNormal><span lang=EN-GB style='font-size:10.0pt;font-family:"Arial",sans-serif;color:navy'> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-GB style='font-size:10.0pt;font-family:"Arial",sans-serif;color:navy'>This is not a hair-splitting detail, it’s fundamental: it’s misleading to say that a process <i>“requires</i>” something that may be involved in some instances but in others it will not be.

Regarding your comment "<i>The whole photon does not possess the properties it takes to be confined to become and electron</i>” John W (and Martin v d M may) suggest that it is possible, John W has also used some mathematics sin support of that proposal.. When a full circularly polarized photon makes two revolutions per wavelength the electric polarities and magnetic fields reinforce each other. This does not occur with any other combination of rotations per wavelength. That model explains many known electron properties and makes many predictions that can be tested experimentally. IMHO that gives a way that full photons can give rise to particles in general and electrons in particular. <o:p></o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'><o:p> </o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'>Grahame, I agree that a "</span><i><span style='font-family:"Arial",sans-serif;color:navy'>a linear photon could not by itself form an electron</span></i><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:navy'>”</span><span style='font-family:"Arial",sans-serif;color:navy'>. It requires an interaction with matter. Without going into great detail, it is not unrealistic to expect that, at such interaction or collision the photon could “crumple” or bend and split. Half the photon would be confined to a negative charge, an electron, and the other half to a positive charge, a positron. Without a definition of a half photon, I am not sure how that idea differs from particle/anti-particle formation from a single energetic photon “splitting” into two confined “half photons”. As mentioned above, a circularly polarized electromagnetic wave making two revolutions within its wavelength will reinforce its electric and magnetic properties in a way that no other combination of rotations per wavelength can.</span><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'><o:p></o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'><o:p> </o:p></span></p></div><div id="bloop_customfont"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'>It would help your case if you were to give a description of half a photon and how "</span><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:navy'> <i>two half-photons (of requisite energy) can form an electron</i>”</span><span style='font-family:"Arial",sans-serif;color:navy'>.

My concept of a 'cyclic photon' is that of an electromagnetic waveform like a linear photon, but constrained by its own electromagnetic field interactions to travel in a cyclic path rather than linearly. In my parlance this doesn't make it 'not a photon' - it depends on whether one's definition of a photon is necessarily something that travels in a straight line or whether one regards it simply as a packet of electromagnetic energy in the form of a self-propagating time-varying electromagnetic field effect: the latter is my understanding of the term.</span><o:p></o:p></p></div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:navy'>So whilst I don't totally agree with Chip's view that there isn't a photon circulating in (or rather AS) an electron, this is due to our differing views on what constitutes a photon - it appears that we're agreed on what constitutes an electron.
