As with many students who seek intuitive understanding of the tenets of physics, I was disturbed that as we approached the more fundamental entities, our descriptions became more complicated. Clearly we are required to depart from physical and intuitive descriptions to more purely mathematical ones. The photon, with its quizzical properties of duality, speed variance, masslessness, energy transfer and quantum nature was most unsettling. It is my belief that our difficulty in such matters is not that they are intrinsically physically inexplicable, but rather that we have placed ourselves in a position of having the wrong perspective. This paper is a humble attempt to look at the photon from a different view while hopefully clinging to physical fundamentals. Sadly, much is left that is not intuitively clear, however, what has been examined appears to be a close fit with observational phenomenon.
The photon model to be described is one in which fundamental relationships are employed in ordinary ways. Although it utilizes a particle that has been previously explained otherwise, its resurrection in terms that are to be described seem appropriate.
DIRAC'S SEA OF NEGATIVE ELECTRONS
Dirac's picture of the energy level distribution of the particles with positive and negative mass. On the left (a) all negative energy levels are completely lined up, and only six ordinary electrons can exist on the normal positive levels. On the right (b) one of the electrons from a negative level is lifted to a positive level, leaving behind a "hole" which behaves as an ordinary positive electron with positive mass. If this extra electron from a positive level falls back into the hole (annihilation process of an e- and e+ the energy difference will be emitted as X-radiation.
The concept of all energy states being filled is not possible to visualize. The idea of infinite negative mass occupying all infinitesimally small volumes of space is simply beyond fathom. It is equally disturbing that if there were an incomplete set of free negative energy particles about, they would all clump together since they accelerate in direct opposition to their Coulomb forces. A variation on this theme, however, has beauty, balance and relieves us of most of these problems.
A VARIATION ON DIRAC'S THEME
First, suppose that the idea of negative energy is an artifact. Consider that although we will use negative energy in our mathematics we are really dealing with negative mass and that negative mass can acquire positive energy, i.e., adding positive energy to a negative mass increases its velocity. We must also assume that positive mass electrons can never become negative mass electrons by "falling into a hole in the sea of negative energy states." The converse of this must also be assumed. We will also assume that positrons are free negative mass negatively charged electrons which fate is to quickly pair up with ordinary positive mass electrons. In this model, as in Dirac's, symmetry prevails. However, instead of all negative energy states being filled below the -moc2 energy level, each negative mass electron is paired with a positive mass electron. As will be shown, the pair, unless stimulated by an external force, will exist on the zero energy level as a stable system. The picture of the static electron universe then is quite different from Dirac's view.
The pairing process, fundamental to this model has been considered before by Dirac and is described in Gamow's, "Thirty years that shook physics." Pairing was dismissed due to our inability to confirm it's existence. Pairing involves a relatively simple, but most interesting process. Let us first examine the separate particles. A normal, positive mass electron accelerates in the direction of an applied force. A negative mass electron, however, will accelerate in direct opposite to an applied force. If two electrons with numerically equal masses, but of opposite signs are paired together the results according to Coulomb's law will be that they will accelerate in the same direction keeping a constant distance between them and speeding up to the limit of the speed of light.
All pairs, unless stimulated, exist only on the zero energy line. Pair annihilation yields two oppositely directed photons through stimulation of other pairs by the time varying magnetic fields of the accelerating positive mass electron (pme) and the negative mass electron (nme). The newly formed pair may also become a photon if there remains a net energy surplus after pairing.
Note: At velocity = c in our reference frame (2) the pair has no dimension in its direction of travel (z) and cannot be distinguished from a single particle with zero mass. It is also assumed that the photon energy in reference frame (1) (photons) is equal to the energy in reference frame (2) (ours). That is, the system from which the photon was originated is in the same reference frame (2) as the receptor and no Doppler shift is incurred and,
and that the energy transform from r.f. 1 to r.f.2 is
which allows free movement between the reference frames. Therefore, in the text of the paper the subscripts have been dropped. One is tempted to ask what the equilibrium separation distance (ref. frame 1) is between the two bodies of the pair. As yet, there is no clear answer to this question, but it seems only to be related to the initial conditions of momentum exchange since the pair is stable at any separation distance. In our reference frame, since the pair is traveling at the speed of light, there can be no separation distance between them in the direction of travel (z). This is consistent with current electromagnetic theory where an electromagnetic plane wave has no z component. The idea of a pair of particles summing to zero mass, momentum and energy, traveling at the speed of light and existing in equilibrium, now may start to make a little sense. One objection to this concept might be that since both particles are charge carriers their motion represents a current flow and should be detectable. Yet if we assume that the universe is filled with these particle, moving randomly, there would be no macroscopic (net) current flow or detectable magnetic field.
ENERGY TRANSPORT MECHANISM
With this basis, we can now consider how a paired system might carry with it some energy and thus assume the role of a photon. Given that a pair exists, if a time varying field is impressed upon the system, the two particles, still traveling at the speed of light, will be caused to revolve about a center of masslessness. To show this one must develop the force balance equations for the system in the photon reference frame (1). Using Coulomb's law and assuming point charges,
Note : Epsilon has units of mass and therefore carries the sign of the mass of the particle.
Then considering relativistically the centripetal force
Substituting and combining terms yields the force balance equations for the photons reference frame (1)
Taking either case and solving for r
Assuming that all of the energy added to create the photon is positive. Then
substituting hc / y for moV 2/T in equation (10) yields
and the ratio l / r is the constant 3444.2 +. It is also interesting to note that the fine structure constant is equal to l / 8 pi/ r.
From equation (11)
Solving quadractically for V 2/T and ignoring the imaginary root we obtain
For the present, at least, we shall ignore the imaginary root. The constant l / r provides insight into the dynamics of the photon and its stability. It is the ratio of the period of the photon and the communication time across the diameter of the photon at the speed of light.
It is now useful to translate the two body system at Vz = c
From equation 15 it may be seen that in reference frame (1), the tangential velocity increases with photon frequency. Now, observing the photon as a particle in our reference frame (2), SINCE THE PHOTON HAS NO Z DIMENSION, THE ELECTRONS ORBITAL VELOCITY MAY BE SEEN TO EXIST ONLY In the x direction.
The average electron velocity in the x direction must be
which is constant
Over the spectrum how can Vx vary from zero to near the speed of light in one reference frame and be a constant in another? There is some help in noting that in reference frame (2) equation 17 is used, while the transform needed to get back to reference frame (1) is obtained by dividing equation 17 with equation 14 and solving VT .
Aside from the relationship n = c/ l this result is our first opportunity to transform from one reference frame to another with a DVz = c. __ Everything still works well in our reference frame when Vx is a constant since
and, as may be seen in table 1, is numerically valid throughout the spectrum. There is also a new relationship for the speed of light in that c = Vxl / 4r.
An interesting feature of equations 12 and 15 and table 1 is that when the frequency of the photon is increased to the high end of the gamma ray spectrum, the tangential velocity converges with c, and the photon radius shrinks to less than that of the classical radius of the electron.
QUANTUM MECHANICAL ASPECTS
When the current view of the photon is such that it is quantized at the time of stimulation, the new model may exhibit a quantum nature in itself. There are at least three ways in which this particle might be quantized. First, consider the integer requirements that the Debroile wavelength places upon the circumference of the particle. Starting with the relationships:
We wish to solve for N, the number of possible states.
Substituting c/ Nv for ^d and solving for v
It should be noted that
Which has the same form as the quantum mechanical relationship
A short computer program reveals the number of quantum states possible over an interesting (nonrelativistic VT ) portion of the spectrum. In Table 2, for example, at about 1013 Hz there are 3,162 possible states with a frequency resolution of 1.5 x 103 . Since it is known from observation that these are far to few states, there must be other modes which will reduce the quantum steps. In all of the previous paragraphs, the photon has been limited only to two dimensions. If one considers that there is almost surely motion in the third dimension, then a low frequency rotation about the z axis would, similar to Table 1, expand the possible quantum states to an extremely large number. Additionally, there would be three electron spin states which would be a multiplier of the number of possible quantum states. Clearly, the number of quantum states would be so large as to appear to be a continuum and the photon can take on any quantum value impressed upon it during emission.
The assumption presented early in this paper are clearly in conflict with currently accepted ideas. The positron, for example, long considered to have the equivalence of positive mass with positive charge, nevertheless can be redefined as a negative mass having negative charge and still be phenomenologically consistent. Almost surely, however, the assumptions will require modification to be more general. The reader that stops at the assumptions, because of basic disagreement, will have missed the most salient features of the paper.
The precise agreement of the mathematics with the gross features of the known spectrum cannot be dismissed as merely coincidental. If relativity were not part of the explanation, it might be possible to suggest that the simple exponential relationships provided only superficial agreements similar to early modeling of the atomic structure. However, agreement with the spectrum over 25 decades and with features such as the convergence of tangential velocity and the speed of light and the forced photon stability due to the collocation of fields consistent with force balance are just too compelling to be easily dismissed.
I believe that duality, diffraction, refraction, and all of the other attributes of light can be explained in terms of classical interactions with photons being absorbed and reemitted or simply redirected. However, to present a model without being able to predict previously unobserved or unexplained phenomenon has been argued by some to have no or only heuristic value. Although a growing number of scholars believe this to be a false tenet it is gratifying that this theory does provide sufficient information to fit the former criteria.
