Abstract:

 A one dimensional model is presented, where a single photon, confined in a cavity, gives a model of mass with respect to kinetic energy and inertia. Then photon-mass interaction is reduced to photon-confined photon interaction, where changes are exclusively Doppler based. However the model demands the existence of a photon pool similar to the zero-point radiation as described by H.B.G  Casimir. However this photon pool alone does not stabilize and conserve the distance of the cavity mirrors. A thermal fraction must contribute in addition as it is described in “Gravitational Mass attraction caused by Ultra Long Wave Photons” A cavity in rest or in translation will leave the photon pool unaffected. However during accelerations of a cavity the model predicts a break of the isotropy of the pool photon distribution such, that behind the cavity a repelling and before a co-accelerating force on probes in first order of β is expected. Experimental work on this subject are published in www.christoph-schultheiss.de/experiments_on_gravitational_forces.

 

A.        Introduction

 

The paper aims to model a mass built from a “mass-less” confinement and photons inside the confinement which reflect continuously back and forward along with 180°-Compton collisions. The conclusions evaluated from the model (which can be called photonic mass model (PMM)) rely on 1-dimensional relativistic evaluations. It comes out that the confined photon gains momentum and kinetic energy like a mass. Effects like spin, polarization etc., which demands a higher dimensionality in the description are neglected.

Since the Compton process plays a dominant rule in this paper, it is necessary to recall the main features of collision physics next.  

 

During reflection processes of photons with charged particles the wavelength of interacting photons becomes shifted. This is a consequence of energy- and momentum conservation. It is the conclusion of several authors [1-5], that these shifts are identically to Doppler shifts, i.e. after the interaction a particle moves with  the velocity β´ = v´/c and the interacting photon, coming back from the particle, becomes Doppler red shifted with respect to the relative velocity b´c. This is demonstrated next for an elastic 180° Compton collision:

With the dimensionless abbreviations α = hν/mc2, γ = (1- β2)-½ ,  and for an initial velocity b=0, by means of mutual addition and subtraction the well known solutions of both equations:

 

(1)       Energy:           α + 1 = α´+ γ´

(2)       Momentum:    α + 0 = - α´ + β´γ´ 

are:

(3)                               α´ = α/(1 + 2α)

(4)                              γ´ = 1+2α2/(1+2α)

 

The Doppler equation becomes visible, if Eq.1 and 2 are rewritten in:

 

(5)                             γ´ = α – α´+ 1   

(6)                              β´γ´ = α + α´   

 

(7) Subtraction:           γ´ - β´γ´ = 1 - 2α´        

(8) Addition:               γ´ + β´γ´ = 1+ 2α                                

 

because of the definition equation:     γ´ - β´γ´ = (γ´ + β´γ´)-1       

from Eq.7 and 8 it follows

(9)                            γ´ - β´γ´ = 1 - 2α´ = (1 + 2α)-1  .

A comparison with Eq.3 gives:

(10)                          γ´ - β´γ´ = α´/α  ,

 

which is the Doppler equation.

 

This result recommends the following interpretation:

The Compton Effect can be considered as a two step event. First step is the reflection of the photon, where both mass and photon change from the laboratory system S into the moved collided system S´. Then in a second step the re-transformation of the photon into the laboratory system takes place. In this step the Doppler red shift as formulated in Eq.10 occurs. This shift corresponds exactly to the velocity difference ß´ energy and momentum law demands.

For an initial velocity b, the elastic Compton shift appears in the form of a product of two Doppler transformations, where the additional transformation describes the entering into a system of the particle in rest before the collision.

Analogous to the equations 1 and 2 the energy- and the momentum law have the form: 

 

(11)                            α + γ = α´ + γ´            

(12)                           α + βγ = - α´+ β´γ´ 

 

With the abbreviated Doppler factors D = γ (1 – β),  D-1 = γ (1 + β)  the solutions are:

 

(13)                           α´= αD2 (1 + 2αD)-1

(14)                            D´ = D (1 + 2αD)-1,

D´ and  α´ relate to the observer. Kinetic energy (γ – 1) can be determined by D´, using the definition equation γ´= ½ (1 + D´2)/ D´. This gives:

 

(15)                           γ´- 1 = 2α2 D2 (1 + 2αD)-1  

 

Together with equation 13 equation 14 makes visible that:

 

(16)                            α´= α DD´

 

energy- and momentum of  the photon is changed exclusively by products of Doppler shifts.

 

Before the collision in the system of the mass (MS) the colliding photon has α D. After the collision the mass system MS´ moves against MS with a velocity corresponding to

 

(17)                          D  = D´/D = (1 + 2αD)-1

 

and the energy of the reflected photon with respect to MS is α DD.

In this sense Tab.1 shortly summarizes this:

 

The photon α leaves the laboratory system (LS) and changes into the moving mass system (MS) as αD. Then it reflects elastically and returns from MS´ unchanged in momentum back to MS as αD. On the way back to LS a second Doppler shift occurs and αD changes into αDD´, respectively in αDDD (see Eq.17).

 

For the violet shift case, i.e. b ―› - β , D is replaced by  D ―› 1/D.

Since a change of photon energy is exclusively subject of Doppler shifts (see ref. 3-6), the Compton collision for this kinematics can be derived directly from momentum- and Doppler laws:

 

(18)     Momentum                  α + 0 = - α´+ β´γ´ 

(19)       Doppler                      α´ = α γ´(1 – β´)

The Doppler equation gives                

(20)                                     β´ = (α2 – α´2)·(α2 + α´2)-1  and   γ´= (α2 + α´2)/2αα´    

 

Inserted in Eq.12 the solutions Eq.3 and 4 follow, without taking direct use of the energy law. The elastic Compton Effect seems to be reasonably described by momentum and Doppler law. The question arises, why the energy law in the calculation Eq.1-10 describes the situation too?

 

To answer this question it is tried to proceed a step more. CCM gives the possibility to reduce the photon-particle interaction solely to a photon-photon interaction theatre, where the mass itself is modeled by photons. This means, photons are confined in a cavity, reflect back- and forward between two mirrors and built rest energy. Movements of the cavity imply Doppler shifts of the cavity photons and besides the rest energy a kinetic energy term appears. Therefore a collision with a free photon leads finally to Doppler shifts of all involved photons – no matter free or confined. To simulate real elementary particles the transition from a mass-loaded cavity to a mass-less cavity is unavoidable. A non-closed physical system must be taken in account to stabilize the geometric arrangement of the cavity mirrors, i.e. the mirror distance. This calls for the cooperation of a surrounding photon radiation field quite similar as described with the zero-point radiation of the space by Casimir [6]. However, during acceleration of such a modeled mass, anisotropy effects in the radiation field in the vicinity of the mass are the consequence.

 

It is not the intention to assert that the CCM frame always reflects reality, but it could, because conservation of momentum and Lorentz transformation are doubtless the most basic fundaments of nature. Therefore conclusions which result from of CCM are worthwhile to be attended and discussed.

 

 

B         Confined light in a cavity which is in rest or in constant movement

 

A model on the basis of CCM is presented, where the mass is assembled by a cavity, consisting of a pair of mirrors in a fixed distance which contains confined photons. Photon – particle interactions become reduced to free photon - confined photon interactions, if the cavity mass is assumed to be zero. In the next chapters the behavior of a cavity filled with photons is subject of investigations with respect to rest, movement and acceleration.

It is well known that the reflection of moving waves at a mirror build up a standing wave pattern in front of the mirror. In a cavity, which consists of two parallel oriented ideal conducting mirrors in a distance of L, only a selection of standing waves following

 

(21)                            L = ½ (j-1) λ,      where    j = 2,3,4,….

 

is allowed.  These standing waves can be populated with an arbitrary number of confined photons. In this one dimensional model spin effects will be neglected, only momentum exchanges during collisions are subject of interest.

 

Figure 1, left graph, shows such a cavity in a Minkowsky space-time presentation. The mirrors built vertical time-lines in a distance of L. The wave front - drawn as a dotted line with arrow - and wave end - drawn as  full line - move in a zigzag under 45° upward inclined with the speed of light. The wavelength (thick arrow) is horizontal, i.e. purely space like. The length of the wavelength arrows in fig.1 correspond to the case λ/L = 1. Additional fig.1, right, shows a Lorentz transformed space time frame of the same cavity in a movement to the right.

 

 


Fig.1:  A cavity in rest (left) and in movement (right) to the right in the frame of a Minkowski space-time presentation. The 45°-lines in both presentations represent the zigzag spread of the wave-front (solid line) and the wave-end (dotted line) for the case l /L = 1. The thick arrows are connection lines between wave-ends to –fronts. In a system in rest they are designated with „wavelength“. In a moving system (right) the wavelength becomes a 4-vector (see Appendix II).

 

On the basis of a common zero point respectively a space time cross point the expressions of the Lorentz transformation are:

                                   ct´= γ (ct- βx)

(22)                             x´ = γ (x- βct)

In fig.1 the observer moves to the left. Therefore b is negative. The relevant transformed coordinates are:

(23)                             (0,0)´= (0,0);

(24)                             (L,0)´= (gL, bgL);

(25)                             (0,L)´= (bgL, gL);

(26)                             (L,L)´= [gL(1+b), gL(1+b)];             

(27)                            (0,nL)´= (nbgL, ngL);

(28)                           (L, nL= [gL(1+nb), gL(n+b)];

 

The transformed wavelength is a 4-vector. Space- and time interval of the wavelength is:

(29)                             (0,0)´- (L,0)´ = [-gL, -bgL]

and for the following point pairs:

(30)                             (L,L)´- (0,L)´ = [gL, bgL]      

and so on.

 

1. Real cavity versus ideal cavity

 

For many aspects fig.1 does not fit for a “ free” particle, build solely from  confined photons in an at last mass less cavity. Assume two photons with a phase difference of p in the cavity. At any time, the momentum transfer of the left reflecting photons must exactly and instantaneously be equaled by the momentum transfer of right reflecting one to hold the mirrors in rest. Mass-less mirror-connection-rods for momentum transportation are physically not available; instantaneous momentum transfer contradicts to the limitation of the speed of light. In addition any mass-like rods lead to diameter vibrations and increase the interior energy. In this case the energy law for inelastic collisions is:

 

(31)                         α + 1 = α´ + δ´+ γ´   

 

where d´ represents the vibration excitation. Nature tells that in elastic photon-elementary particle interactions the term d´  is normally zero. Therefore a model of mass, relaying on confined photons seems to be a complicated or even an unrealistic undertaking. The problem is to find a mechanism which efforts seeming instantaneous momentum transfer from one mirror to the other.

 

Two solutions are offered next. The first one is a dynamic mirror system, where nearly mass less mirrors experience a centripetal force by means of elastic bands and are oscillatory pushed out by the collision momenta of at least two confined photons with π phase difference. The other solution, which is favored by the author, is the action of a  pool photon theater where outside photons reflect simultaneously with confined photons and compensate any mirror momentum (see Chap.3).

 

2. Dynamics of nearly mass-less cavity walls

 

Concerning the dynamic mirror system one has to imagine mirrors which are connected by elastic bands. The elastic bands are in tension because of innumerous collisions of confined photons at the mirrors. This means every time a confined photon reaches one mirror, the mirror flies inward. After the collision the mirror flies outward with exactly the same value of velocity.

The energy and momentum equations for the oscillation are:                  

(32)                            α + γ = α´ + γ´               

                               - α + βγ = α´- β´γ´ 

because of the oscillatory boundary condition the momentum equation result in:

(33)                                                α = β γ   

 

respectively in physical properties

 

(34)                                     h/λ = βγ mc              .

 

The interesting feature of course is the reduction of mirror mass with the boundary that the photon momentum h/λ remains constant. This means γ must grow enormously i.e.,  ß → 1 must be valid and therefore equation 34 becomes:

 

(35)                                        γ mc ≈ h/λ     respectively      γ ≈ α         

 

For very high values of γ the space time curve reminds to that of light.  Reflections i.e., reversal of movements are sharp corners and curves are straight lines which meet themselves under the angel of 45° (see fig.2). 

 

Fig.2: Space time graphs of a cavity in rest (left) and in movement, where nearly mass less mirrors oscillate (grey area) by means of a centripetal force originated by elastic bands and a centrifugal force generated by reflecting confined photons

 

The oscillation area of the mirrors (grey marked in fig.2) is ½ L for two confined photons which are in a phase distance of π.

 

The energy of the whole system is distributed between the mirrors and the confined photons:

 

(36)               Ehv/Emc2 = hν/γmc2 = α(1+α2) = (1 + 1/α2)  ―› 1   for   α  ―› ∞

 

In the extreme case, where α and γ → ∞,  ½ of the energy is distributed to the nearly light fast mass and ½ to the confined photons.

 

At a first glance the light fast mirror behaves like a photon. The question is, does it transform like a photon or like a mass proportional with β2?

 

The definition equation for the relativistic mass 1 for the high-gamma case is:

 

(37)            1 = m (1- β12)   ,

 

where β1 defers only marginally from 1. Now the cavity moves with a velocity β2 which is small against 1. The increase of energy for the light fast mirrors can be calculated by applying the relativistic addition law:

 

(38)                

 

Using the definition equations for γ we have

 

(39)               m γ´  = m γ1 γ2 (1 - β1 β2 ) = m γ1 D2

 

and the prove that the light fast mirrors transform like photons is carried out. During a movement of the cavity with ß2 and as a consequence of the oscillatory movement of the mirrors with ß1 they experience red- and violet shifts corresponding to β2 while the confined photons experience violet-and red shifts in the same rhythm.

This Doppler shift theatre which comes up with the dynamic mirror model can be also found in the mechanism shown next.

 

3. External photon pool similar to Casmir’s zero point radiation defining cavity walls built from mass-less mirrors

 

An alternative mechanism to stabilize the mirrors could be an external photon theatre (pool) as can be seen in fig.3. Mass-less mirrors are embedded in a standing wave field of pool photons. Mirror reflections of confined photons take place in phase with reflections of pool photons at the rear mirror side – a process which is proposed to be called in-phase.

 

 


Fig.3: Space-time frame of the compensation of mirror reflection momenta by instantaneous reflections of external photons (thick arrows) coming from a pool. This process will be called in-phase.

 

By the action of pool photons each mirror separately remains in rest or in constant movement during the reflections. Of course the momenta of confined- and pool photons are assumed to be equal.

With the tool of an external photon theatre the model of a free particle build solely from confined photons can be investigated. However serious demands meet the photon pool, which has to spend a photon spectrum at any time at any place to conserve geometrical properties of particles and to hold them stabilized.  This will be a subject of the next chapter too.

 

4. Doppler shifts at a moved mirror during in-phase

 

If a cavity is in rest, an observer state, that confined photons α* and counter-flowing pool photons αp reflect instantaneously, as shown in fig.4 left graph. If the cavity plus pool cavity or the observer moves, all photons, which interact with the cavity mirrors, underlie Doppler shifts. With the abbreviations D = γ (1 – β) and  D-1 = γ (1 + β)   pool photons moving to the right are transformed into (see fig.4):

 

(40)                            αp   ―›   αp D-1,

 

and after the reflection, moving to the left, the transformation is:

 

(41)                             αp   ―›   αp D .

 

For confined photons in the cavity the shifts are vice versa i.e., D has to be replaced by D-1 .

 

Figure 4 shows the reflection situation of at the left mirror of a cavity in rest (left) and in movement (right). At the opposite mirror the situation of pool- and confined photons is just vice versa for both cases (not shown in fig.4).

 

 


Fig.4: Space time presentation of confined- and pool photon reflections at the left cavity mirror in rest (left) and in movement (right). Since momenta of photons are equal the mirror remains in rest or in constant movement after reflection.

At a first glance the standing wave situation in a moved mirror seems to be destroyed because of different wavelengths of red- and violet shifted waves. However relativity contradicts which will be demonstrated next:

 

A standing wave in a cavity is equivalent to a standing wave in front of a mirror in rest. One wave moves to the right, the other one to the left:

 

(42)                          F(x-ct) = eiω (t – x/c)   

(43)                          F(-x-ct) = eiω (t + x/c)     

 

Superposition of both waves gives (reflection at a mirror):

(44)                 y = F(x-ct)-F(-x-ct) = eiω (t - x/c) e iω(t + x/c)  = e iωt eiωx/c - e iωt e iωx/c = e iωt (e-iωx/c – e iωx/c ) = -2i eiωt sin(ωx/c)

                                         

a standing wave.

 

Lorentz transformation:  ct´= γ (ct- βx)

                         x´ = γ (x- βct)

 

(45)     F´(x-ct) =  e iω/c [γ(ct-βx) – γ(x-βct)] = e iω/c γ(1+β)·(ct-x) = e iω/c·D · (ct-x)   wave violet shifted!

F´(-x-ct) = e iω/c [γ(ct-βx) + γ(x-βct)] = e iω/c γ(1+β)·(ct+x) = e iω·D/c · (ct-x)   wave red shifted!

 

(46)      y = F(x-ct)-F(-x-ct) = e iω/c γ(1+β)·(ct-x) - e iω/c γ(1+β)·(ct+x) = e iω/c γ(ct+x) e iω/c γ(ct-x)β - e iω/c γ(ct+x) e iω/c γ(ct+x)β =

                = e iω/c γct ·e -iω/c γx· e iω/c γctβ· e -iω/c γxβ - e iω/c γct ·e iω/c γx· e -iω/c γctβ· e -iω/c γxβ =

                = e /c γct ·e /c γctβ· (e -iω/c γ(x-βct) - e /c γ(x-βct)) =

                = - e /c γ(ct-xβ) 2i·sin[ω/c γ(x - βct)]                          

or rewritten:

 

(47)            y´ = - e iωt´ 2i·sin(ω x´/c)               

gives the expression of a moved standing wave.

 

A moved standing wave remains a standing wave, although photons underlie Doppler shifts. Red- and violet shifts do not imply a phase mismatch of the standing wave in a cavity, although the lengths of the waves are different. Such conclusions will not appear if consequently the real- and the complex term of the wave are considered in calculation. This result is also in agreement with the well known invariance of the wave number as well as with the invariance of the phase in SR [7].

 

In contrast to the behavior of free photons, confined photons in a moved standing wave underlie length contraction (transversal Doppler effect) and time dilatation just as it is with moved masses. Therefore photons in a standing wave lose characteristics like “free, non localized in an area” as well as “undergoes longitudinal Doppler shifts”.

 

The over-all momentum- and energy situation in the pool remains unchanged for a moved cavity. Reflected, Doppler-shifted pool photons like αp D (see in fig.4 right graph) have the same energy as if they approach from the opposite side and penetrate the cavity (α*D represents this). Locally it looks like a transfer from the pool- into confined photons and then as a transfer back into pool photons:

 

(48)                 αp DLeft ← α*D ← αp DRight        

            αp D-1Left → α*D-1αp D-1Right         

Equations 48 give a proof, that the neutrality of the pool distribution is not disturbed by the presence of a cavity, this is in rest or in constant movement.

 

The demands on the quality of space, as sketched shortly above, seems to be unrealistic. But in the field of QED, Casimir and Polder predict in 1949 zero point radiation in space of a quality, which may be able to fulfill such demands [8].  The space is filled with electromagnetic zero radiation of nearly unlimited energy. Electrical conducting plates as shown in Fig.x  positioned in a distance L underlie apparent attraction forces, resulting from the fact that inside the cavity only standing waves with λ = 2L, L, ⅔L, ½L,… and outside in addition a pattern of standing waves with λ = 4L, 6L, 8L, … is established. Therefore the flux of photons outside the plates is larger then inside the cavity. The computation gives:

 

(49)   p = ħc π2/(240 L4) = hc π/(480 L4)  = 1.3 10-3 Lμ-4   in  N/m2,

 

where L is the plate separation in Meter respectively Lµ in Micrometer. Several authors could positively measure the so called Casimir force at metallic foils positioned in a mutual distance of micrometers [9].

 

 

 


Fig. 5: Two conductive plates in a mutual distance L , where the number of modes inside is lower then outside with the consequence that the outside long wave modes generate a in-ward directed pressure to the plates

 

A cavity embedded in zero-point radiation will experience a overshooting outer pressure coming from the long wave spectrum, corresponding to L-4 , enormous at atomic dimensions.

The overshooting outer pressure may balance inside reflecting thermal confined photons. The pressure of a confined photon in a gap with distance L, wavelength λ = L/2, a non-relativistic momentum transfer of  2h/λ during reflection and an area of approximately L2:

 

(50)        pconfined = ½  hc/L4      

 

A comparison with Eq.49 shows that the pre-factor in Eq.50  is somewhat above 70, i.e. an expansion of the cavity will take place. Roughly seen, a thermal fraction with wavelengths above L must support the long wave zero point radiation:

 

(51)             hc π/(480 L4)   +     ½  hc/L4 · (1-π/240)    =    ½  hc/L4           

 

The stabilizing thermal fraction (second term in Eq.51) could be the searched fraction of ultra long wavelength photon, which is a possible candidate for mass attraction respectively gravitation see http://www.christoph-schultheiss.de/gravitational_mass_attraction [10]. If this is true, a unified theory between photonic mass and gravitation appears.

 

 

5. Behavior of confined photons and comparison with classical mass

 

To close the aspects of a moved cavity the average energy of one confined photon or of confined photons are derived next:

Figure 4 demonstrates that confined photons in a moved cavity underlie Doppler shifts, which are in equilibrium with Doppler shifts of pool photons, so that the mirrors stay in rest or in constant movement during reflections. Therefore the diameter of a cavity is an invariant.

 

A confined photon has the momentum α*D-1 in flight and α*D in counter flight direction. The behavior of standing waves (see above) tells that this is true for a cavity in rest as well as in movement. Thus the averaged energy contribution α* of one confined photon is:

 

(52)                      α* = ½ (α*D-1 + α*D)  =  γ α*      ,

 

an expression, which can be called as  the kinetic energy of a confined photon.

 

Since there is no difference between momentum and energy of a photon except of a constant, which is the speed of light, the Einstein rest energy formula E = m c2 can be understood as a scalar summation of all confined photon momenta h/λ. The scalar momentum p* = m*c of such a mass is (n is the number of confined photons):

(53)                       m*c = ½ n h/λ*·D-1 + ½ n h/λ*·D  =  ½ n h/λ*· (D + D-1)  = n γ h/λ*     

 

Analogue to Eq.53 the resulting vectored momentum of all confined photons give the resulting mass momentum:

 

(54)                      m*ĉ = ½ n h/λ*·D-1 - ½ n h/λ*·D  =  ½ n h/λ*· (D - D-1)  = n βγ h/λ*               

 

The physical meaning of a scalar momentum m*c of mass is: if all confined photons Σn h/λ* escape in one direction, the resulting repulsion momentum is mc.

 

As can be seen in Eq.53 and 54, the left hand properties like kinetic energy and momentum relate to a classical Newtonian mass and the right hand terms relate to corresponding Doppler shifts of counter-flowing confined photons in a cavity:

 

(55)                       =  D-1 + D              

(56)                     2βγ =  D-1 -  D       

 

The expressions have the form of mass - confined photon -equivalence equations.

 

Both models, namely the dynamic mirror mass model (see derivation Eq.32 -39) as well as the above described pool photon model with embedded cavity have charming aspects. However, later investigation shows that only one confined photon per cavity is allowed in order to fulfill momentum and energy law. This excludes the dynamic mirror model which demands minimum two photons with a phase deviation of π.

  

In the next chapter it is assumed that a mass, modeled by confined photons embedded in a photon pool, underlie a Compton Effect with free photons. This leads to a complex interaction between three light fast partners namely: free-, pool- and confined photons.

 

 

C.         Cavity velocity change and discontinuous acceleration; polarization effect of pool

 

Let a free photon a collided with a cavity in rest. This is a situation, which is described by a 180° Compton collision. After the collision the cavity moves. Let, during a time interval, further free photons hit the moving cavity, then this can be considered as a model of mass acceleration. Of course the acceleration is not of continuous but of discontinuous nature. As already mentioned it is the intention of this investigation to avoid notions like forces and fields to describe velocity changes, as long CCS can be used. Fields and forces are replaced by a swarm of photons. Forces result from series of photon collisions of with particles etc..

 

As can be seen from fig.1 and 3 a transition from rest to movement is a transition from a cavity diameter  L to L/g. In addition a phase relation for transition of a confined photon in rest into one in movement has to be taken into consideration. A simple connection frame is shown in fig. 5. It comes up, that after the start of the front mirror the rear side of the cavity starts with the delay D with movement.

Fig.6: Principle space-time frame of a discontinuous transition of a cavity in rest into one of movement. Front and rear side of the cavity start movement at different times. This generates relativistic length contraction of a moved system.

 

By means of elementary geometry the transition time D can be evaluated to:

 

(57)                         Δ = L (γ-1)/βγ   

 

In the transition from rest to velocity an already mentioned phase correlation is necessary between the Compton collision and the internal confined photon reflections. Only for the special case of a j -delay between the Compton free photon- and confined photon reflection the phase relationship between of the confined photons in the moved cavity is correct and relativity is fulfilled. j  is derived using geometrical properties shown in fig.6:

The line through (½L-½L/γ, ½L) with the direction factor β-1 cross the vertical line x = 0 at j:

 

(58)                        φ = ½ L - ½ Δct  = ½ L[βγ – (γ-1)]/βγ    

 

This means, either the collision with free-photon only takes place if the j -phase relation with confined photons fits exactly accidentally, or confined photons leave the cavity and become ex- changed by pool photons of equal momentum but with correct phase relation. In fig. 7 the exchange of confined- with pool photons in order to restore phase correlation is sketched. Of course leaving confined photons convert into pool photons and entering pool photons become confined one.

 

 


Fig.8: The transition of a cavity in rest into a moved one demands an exchange of two confined- with two pool photons  in order to conserve the mutual phase relation between confined photons in rest and in movement 

 

 

Let’s start the investigation with the assumption that two confined photons α* will be emitted into the pool and convert to pool photons. This emission does not change the isotropy of pool photons. But, the absorption of a violet-shifted pool photon αp D-1 and the red-shifted pool photon αp D by the cavity release corresponding pool photons in counter flight direction. The consequences on the neutrality of the pool are investigated next:

 

Equation 59 is the momentum frame before the reflection. All involved photons are listed and ordered in free-, confined- and pool photons. When a collision happens, one half of the confined photon moves to the right (notation R) and one half to the left (notation L).  A rearrangement of the terms after the reflection is sketched in Eq.60. If only one confined photon populates the cavity then n = ½ and one of the notations (left or right) must be cancelled. .

  Pool Photon

 

Since in Eq.59 and 60 momentum law is conserved for free- and cavity photons, the terms of the pool have to be equal too. The result is (α´ =  α D):

 

(61)                α = - α´ + 2nα*(D-1-D)

                                              ←—→

                                               2β´γ´

            

a momentum equation with a pre factor of 4 n instead of 1 i.e., solutions with 2 (n=1), 4 (n=2) etc. confined photons contradicts to the momentum equation. However if the cavity contains only one confined photon (n=½) we have:

 

(62)                           α = -α´ + 2 ½ α* [2β´γ´]

 

                                  α = -α´ + β´γ´

 

which is the exact momentum equation since for one confined photon . This means exactly one confined- and the counterpart namely one pool photon are involvd in the cavity frame.

This simple model tells that in the cavity two half-waves move in opposite direction. The confined photon is in the ground state respectively it represents the zero-point energy of the cavity. 

 

The appearance of a polarization effect in the pool can be stated, depending on the flight direction of the confined photon during collision. Terms of Eq.59 and 60 are sketched in fig.9.

             

Fig.9: Anisotropic spread of pool photons after a Compton collision as shown in Eq. 59-60. The process free photon a change to pool, a D change from pool- to free photon” is circled. The pool photons, which left, are emitted in back and in forward direction. Depending on location (in front or behind the dotted line) probes experience co-acceleration or repelling.

 

To close the consideration, the equations 61 and 62 can be written in the energy form. There all terms are positive.

 

(63)     “before”          

 

(64)     “after

 

 

Since in Eq.63 and 64 the energy law is conserved for free- and confined photons, the terms of the pool have to be equal too. The result is:

 

(65)                            

 

With the notations analogous to Eq.62 and n = ½ the energy law results

 

(66)                            

 

This result again confirms the validity of the single confined photon frame (for n = 1 Eq.65 gives , which is wrong!).

 

 

As can be seen in the pool term of Eq.59 the pool is not neutral before the reflection, since it contains , approaching from the right to the cavity. Fig.8 tells that after the reflection for the case n = ½ (only one confined photon) the pool either emit  or   , depending on the flight direction of the confined photon. In a statistical average – if locally many Compton collisions happen - the - terms vanish and   is valid.

 

The cavity seems to emit pool photons in both directions (see fig.9) with a little increased strength in backward direction. This can be seen for :

(67)

 

Therefore in summary on can state: during a Compton collision mass probes in the vicinity of a cavity may experience a repelling force by the cavity in both directions with a increased strength in backward direction. The isotropy of the pool is locally violated; but conservation of energy and momentum are not affected by this process.

 

D.              Conclusion

As mentioned above and as can be seen in Fig.9 during a Compton collision the pool is not neutral. This is also true for series of collisions respectively during a continuous acceleration of a mirror mass in the course of processes with energy conservation. An exception of course is the acceleration of a mass in a rotating system. Here an increase (or decrease) of the angle velocity unbalance the pool. There is no indication that the centrifugal force alone causes a pool violation (see recent experiments with rotating (superconducting) discs with expectations of virtual generation of gravitational forces or screening). The force which results from the change of the angle velocity in the vicinity of a rotating system is studied in experimental works of the author and is published in www.christoph-schultheiss.de/experiments_on_gravitational_forces .

[10] Main subject of the paper http://www.christoph-schultheiss.de/gravitational_mass_attraction is the assumption that an intense isotropic ultra long wavelength (ULW) photons distribution exists in space (a comparable small thermal spectrum over Casmir’s zero point distribution) which causes virtual attraction forces by means of electromagnetic scattering. However the intensity of the ULW electromagnetic radiation in this theory can vary in a wide range. With the cavity stabilisation formula (see Eq.50) an estimation is possible:  The momentum per second (in 4π) an elementary particle (proton) experience is about 3/2 · h/L4 · L/c ~ 104 . In the “mass attraction” paper the momentum flow is given by: Photon flux j times momentum of a ULW photon (10-60 kg m/s) i.e.  j · 10-60. The comparison gives: j is about 1064. Such a value indicates that the cross section for gravitational electromagnetic scattering is determined by the very tiny value of the Planck length.
