Does Light Exist Between Events?

by Jim Walker

originated 28 Dec. 1998

"One might still like to ask: 'How does it work? What is the machinery

behind the law?' No one has found any machinery behind the law. . . We

have no ideas about a more basic mechanism from which these results

can be deduced."

-Richard Feynman

PREFACE

Perhaps we cannot find a basic mechanism of light for the simple possibility that it maynot exist. Whether it exists or not between events, I cannot imagine a more wonderfully

perplexing and yet seemingly ubiquitous phenomenon as that of light. I use the term

"light" in its general sense as that energy which allegedly pervades our existence and

which physicist's call the electromagnetic force or electromagnetism (EM). It

encompasses the entire spectrum from low frequency (long-wavelength) radio waves,

heat (infrared), visible light, X-rays, and to the most energetic gamma rays. Quantum

physicists today describe electromagnetism as one of the four elemental forces of the

universe (the other three consist of the weak force, strong force, and gravity).

Almost everything we sense, see, touch and feel comes as a result of this force; it holds

atoms together, creates the properties of chemistry and of every element in the periodicchart. Our every thought consists of electrochemical patterns. We cannot exist and, in

fact, we consist of the reactions of the electromagnetic force within matter. Yet this

most common "thing" remains completely inexplicable. We know nothing at all about

its physical mechanism.

By inexplicable, I mean it in its philosophical sense rather than the scientific.

Scientifically, light has received the most scrutiny of any other force and provided

physicists with its most acclaimed successes, with predictions within one part in

millions. Newton, Maxwell and Einstein have produced theories and mathematical

descriptions that, through their understanding, have emerged technological

achievements such as radio, television and lasers. Yet the success of these scientific

theories have thrown virtually no light (pun intended) on the nature of the mechanism of

light. How does it actually exist in nature? How can it travel through space? If it exists

in space, what describes its shape, size, and boundary limits within space-time? How

does this mysterious "action-at-a-distance" occur? No one has yet come close to

accurately describing the alleged corporal substance of this ethereal phenomenon, and

certainly not without also producing insurmountable paradoxes. Needless to say, the

inconsistent descriptions present epistemological problems as well as ontological. Can

we actually know anything about sole photons? Perhaps, even in principle, there occurs

a quantum barrier to forever prevent knowledge of them. Or perhaps there exists

nothing for us to know about; maybe light does not exist at all between emission anddetection!

In this treatise I have no intention to show that the phenomenon of light does not exist.

On the contrary the vast experimental data provides ample evidence that something

occurs at the events. By "event" I mean something happening. For example the source

(emission) of light and the detection of light act as measurable events. But where else

does it occur? Our descriptions of light forces us to think of light as traveling through

space, either as wave, particle or a union of both. But in doing so, we come up againstinsurmountable logical problems when we try to apply these descriptions to the double-

slit experiment or the three polarizer problem. Can we describe light in another way that

upholds the data yet eliminates the paradoxes without contradicting the mathematical

models?

I will attempt to show that part of the problem may come, not from the nature of light,

but in our unexamined use of language, the way in which we try to describe light, and of

the philosophical beliefs held by scientists in their attempt to explain the properties of

light. Because of the impreciseness of our spoken language, paradoxes and fallacies

emerge that tend to confuse rather than to reveal. So also do scientists have their

favorite beliefs, perhaps unconsciously born into them from Aristotelean beliefs,learned from rote teachings that appear absolute and unforgiving. I intend to show that

perhaps many of the properties of light do not occur "out there" but only in our heads.

Indeed, the phenomenon of a discrete packet of energy traveling through space might

not exist at all, but rather the idea of its existence comes about through an incorrect way

of thinking that derived from the Ancient Greeks and passed onto the 19th century

physicists who created the scientific vocabulary we use today.

THE INVENTION OF PHOTONS

There appears only two ways to avoid action-at-a-distance. Either you propose a wave

traveling through a medium, (like water and sound) or your propose an independent

body that moves from point to point (like baseballs). The idea that light consisted of

corpuscles actually began with Isaac Newton, but the mathematical description of

quanta began in the early 1900s when Planck proposed the quantum of measured

energy. He did not, however, believe in the corporal existence of light. Rather, he

thought of light as traveling through a luminiferous ether in accordance with Maxwell's

light theory, but measured in discrete lumps which he called quanta (Planck, 1909). The

idea of light existing independently as discrete quanta came from Albert Einstein:

"Only the conception of a luminiferous ether as the carrier of the electric and magnetic

forces does not fit into the theory described here; for electromagnetic forces appear here

not as states of some substance, but rather as independently existing things that are

similar to ponderable matter and share with it the feature of inertia." (Einstein, 1907)

Thus Spoke Zarathustra.

I don't mean to chastise Einstein, but rather the leagues of followers (read, believers)

who have transmitted his concept in hundreds of scientific papers and placed it upon an

untouchable pedestal of Truth. Yet few people realize that Einstein gave a heuristic

description of light, not one that he thought of as absolute or as a requirement for histheories:

"For the time being the most natural interpretation seems to me to be that the

occurrence of electromagnetic fields of light is associated with singular points just like

the occurrence of electrostatic fields according to the electric theory. It is not out of the

question that in such a theory the entire energy of the electromagnetic field might be

viewed as localized in these singularities, exactly like in the old theory of action at a

distance. I more or less imagine each such singular point as being surrounded by afield of force which has essentially the character of a plane wave and whose amplitude

decreases with the distance from the singular point. . . I am sure it need not be

particularly emphasized that no importance should be attached to such a picture as

long as it has not led to an exact theory. All I wanted is briefly to indicate with its help

that the two structural properties (the undulatory structure and the quantum structure)

simultaneously displayed by radiation according to the Planck formula should not be

considered as mutually incompatible." (Einstein, 1909) [bold characters, mine]

Compton's work in the 1920s with X-rays and electrons appeared correlated with

Einstein's idea of discrete particles, and this convinced many physicists. And although

Einstein invented the concept of a discrete quantum of energy, the idea of a "quantum"does not necessary impart indepenent existence. The believers of the reality of light

needed a more concrete word. That word came in 1926 from a proposal by the chemist,

Gilbert N. Lewis in aletterto the editor of Nature magazine. Just as had the electrons

and protons, a unit of light (phot) got promoted with the suffix "on" to become a

concrete description of energy as a particle of existence. Physicists could now regard the

photon as real and as fundamental as all the other "on" particles that have the ability to

putt about in free space.

"I therefore take the liberty of proposing for this hypothetical new atom, which is not

light but plays an essential part in every process of radiation, the namephoton." (Lewis,

1926)

From then on, the idea of the independent existence of light, with the blessing of the

great scientist, Einstein, had firmly cemented itself into the lexicon and literature of

science. How could one notthink of light as a particle any more? Like the little man in

this children's poem:

saw a man upon the stair

little man who wasn't there.

e wasn't there again today--

Gee, I wish he'd go away!

Have we hypnotized ourselves into a grand reification fallacy where we have

mistakenly treated our abstractions as a physical reality? (see the "List of common

fallacies")

THE PROPERTIES OF LIGHT

Scientists throughout history have called this mysterious energy by various names: rays,

waves, light, beams, lumiferious ether, electromagetic radiation, quanta, photons,

wavefunction, state vector, and who knows what else. All of the descriptors assume an

existence in space-time.

Below lists just some of claims for this elusive force:

1. sometimes appears as corpuscules2. sometimes appears as waves

3. exibits polarization as a transverse wave

4. the waves can bendaround corners, as in diffraction

5. two waves can sometimes join and cause interference

6. the waves can sometimes bounce off of objects (reflection)

7. the waves can sometimes refract inside certain materials

8. an electomagnetic wave consists of an electric and magnetic field at right

angles to each other.

9. wave & particle does not apply simultaneously to the same phenomenon

(Bohr's complementary)

10. propagates rectilinearly within a uniform medium11. electrons emit photons when changing energy levels

12. upon emission, light achieves instantlight speed (186000 mps).

13. Light cannot travel faster than c but can go slower (in a medium)

14. an electron "absorbs" a photon when changing energy levels

15. can rotate its polarization angle when passing through a substance (Faraday

effect)

16. light can exibit a pressure on matter (P. N. Lebedev)

17. gravity "attracts"(changes freqency but does not slow up) photons

18. a photon acts as the carrier of the electromagnetic force (note this statement

implys two things: a carrier and force)

19. has no mass

20. has a stable lifetime

21. has zero charge

22. has a quantum spin of 1

23. when traveling between source and detector, the photon describes a wave

function. When a detection occurs, the wave function collapses

24. mathematically appears as e=hv. The higher the frequency (v), the higher the

energy.

25. some frequencies of radiation go right through some matter (X-rays, for

example)

26. some frequencies of radiation get blocked (or absorbed) by matter (visiblelight)

27. In a double-slit experiment, the photon seems to go through both slits at the

same time!

Now I ask the reader to try to assimilate these features and attempt a simple

understanding of light. Mind you, this alleged fundamental particle, which has no mass

and has no size, appears to have so many parts and features that a complex carburetor

pales by comparison and with the elusive magic of a Houdini! I submit that something

has gone awry here.

The illustration below describes a typical vector diagram that agrees with Maxwell's

classical wave threory of light. Many high school and college text books use this

version to this day:

This vector diagram shows light as a composite of an electric and magnetic field

traveling through space as a sinosodal transverse wave. The electric wave always travels

at 90 to magnetic wave, so the theory goes.

The illustration below shows a particularly creative attempt that seems to solve thewave particle duality in accordance with de Broglie's wavicle theory:

(Bostick, 1961)

Note how this thread loop (the wave) appears within a discrete volume (the particle). I

must admit, however, that I do not understand this model when you apply it to

polarizers and double slit experiments (and I suspect the inventor had doubts too).

Perhaps the most successful and most abstract view of the photon came from Feynman

in his diagrams that show interactions between mass particles by virtual photons. The

Feynman diagram below shows an interaction between two electrons by a virtual

photon:


6/22

But even in a virtual sense, the squiggly line imparts the idea ofsomethingwith

frequency traveling in space from point 6 to point 5. Of course no one has ever seen

these photons; they exist virtually so they tell us. So do spirits, I hear tell.

"Photons are responsible for transmitting electromagnetic forces. The electric forces that

hold atoms together are in effect 'carried' by photons'." (Close, 1987)

None of the above illustrations show the carrier/force model that agrees with Gilbert

Lewis' and modern day descriptions. Therefore I humbly propose the following model

which I think best describes how the photon carries the electromagnetic force. I haven't

yet worked out the exact shape of the carrier but I think it looks something like this:

Notice the fine streamlined shape for fast traveling through atmospheres (it does slow

down a little bit).

Of course all of these descriptions appear as abstractions and no physicist would dare

make the claim that they describe an absolute description of light. But make no mistake

about it; one thing that most physicists agree with: that in all of their abstractions, they

believe the contention that light (whatever their description) exist as discrete packets ofenergy traveling through space, completely separated from matter.

Do you suppose that, perhaps, a simpler model might work without imparting so much

baggage and paradoxes?

A BETTER MODEL?

Imagine that the phenomenon of light occurs only at the time of emission, reflection,

defraction, and detection in matter, at the electron level, and nowhere else. Immediately,

we eliminate the concept of light as discrete particles or waves traveling through space.


7/22

Once you eliminate the concept of particles, waves and trajectories, the paradoxes,

except for one (I'll explain later), completely disappear!

The equation for electromagnetic energy, e=hv imparts a quantum unit of energy with a

frequency. Yet nowhere in the equation does it say where the energy occurs. Could not

the entire phenomen occur as a function of electron events? Could not an electrontransfer a part of its energy to another electron, not through a trajectory in space, but in

delayed time?

Thinking of light as a function of matter events places the wave-particle duality entirely

upon the experimental set up. If you want waves, your detector must behave in wave-

like fashion. If you want particles, the detector must react as if it detects particles.

Instead of imparting all the myriad of impossible feature to the virtual photons, why not

attribute them to the very material from the emitters, reflectors, and detectors? Quantum

philosophers will note the similarity to Wheeler's "observer creates reality" hypothesis

(Wheeler, 1983). But in this model, either the observerorthe contingencies from nature

supply the materials of reality. (conscious observers need not exist for the reality ofmatter).

To explain it by way of a classical analogy, think of throwing a stone into a pool of

water. You will see concentric waves emanating outwards (wave measurement). If you

throw the stone into a bed of soft sand, you will observe an impact crater (particle

measurement). Now imagine that (for whatever reason) something always prevents you

from seeing the stone. You can only analyse the water and the sand (the stuff of your

detector). Should you impart wave-like and particle-like properties to the stone?

Clearly, imparting the wave or particle-like hit onto the stone would create

unexplainable paradoxes.

The difference in the analogy from the classical model comes with eliminating the

concept of discrete particle entirely. In other words, light does not exist between events,

but only atthe events.

A matter-measurement model of light not only does not contradict any known physical

laws but, in effect, tends to support quantum mechanics. Just as electrons jump from

atomic orbital to another in the Bohr model of the atom, so also can we think of

electromagnetic events that jump from event to event.

Ah, but what of the solid evidence for photons? So much research, so manyexperiments; surely there exists mounds of evidence to throw against this view.

EXAMINING THE CLAIMED EVIDENCE

The challenge may seem incredulous but until someone can provide evidence, I will

have to stand by it, lest I stand among the faithful believers. It amounts to this: no one,

throughout the history of science has ever seen or detected a photon in space! To this

day, there has never existed a single scientific evidential experiment that has shown the

existence of a wave or a particle of light between emission and detection. So on whatevidence do the believers rely on to justify their alleged photons?


8/22

The reason might appear obvious for the quantum philosopher. Since it requires some

material means to detect a photon, we can never observe the alleged photon in its

solitary state. Our emitters and detectors, themselves consist of matter. Therefore,

whenever we detect light, we must do it at some instrument, whether it consists of a

photometer or a biological eye. We simply have no way to look at the alleged photons

in its pristine state without matter getting in the way. (Quantum philosophers might seein this Bohr's insistence of the importance of the measuring instrument in determining

the outcome [Copenhagen Interpretation]). This, of course, did not occur to the first

experimenters of light, and thus we get left with their Classical interpretations. The

following briefly describes why the experimentsseemedto confirm the photon's

existence.

The Compton effect

Although Einstein believed in the independence of light particles, most physicists held

on to the classical view of light. But Arthur Compton's experiments in the 1920s

showed that X-rays can knock electrons about like billiard balls. This finally convincedthe majority of physicists of the alleged particulate nature of light. The Compton effect,

as we now call it, shows the path of deflected electrons in free space when "bombarded"

by X-rays. But Compton's photos never showed the X-rays (Compton, 1926). The

photos only show deflected electrons! Compton inferredthat particles of X-rays

traveled through space simply because the electrons behaved as ifparticles had hit them.

And although the results of Compton's experiments correlated with Einstein's abstract

definition of discrete quanta, correlations do not prove causation.

Bubble chambers

Along with all the instruments of detection such as the Wilson cloud chamber, and

bubble chambers, physicists can detect many of the strange sub-atomic particles by

looking at the tracks of these particles. But even by using these precise instuments, we

cannot detect photons between events. Since the alleged photons have no charge, they

never appear in particle track photos. Only the massive particles that have charge

(electrons, protons, muons, pions, etc.) appear in them. Thus we can only use inference,

without any direct evidence whatsoever to support the notion of discrete light particles

moving through space.


9/22

"Invisible gamma ray photons produce pairs of electrons (green) and positrons (red) in a

bubble chamber at the Lawrence Berkeley Laboratory. The photons come in at the top

of the picture. In the upper pair, some of the photon's energy is taken up in displacing an

atomic electron, which shoots off towards bottom left. In the lower example, all the

photon's energy goes into the production of the electron-positron pair." (Close, 1987)

"Invisible gamma ray photons." "They come in at the top of the picture." I also have it

on the authority of several people, in the know, that poltergeists indicate their existence

by slamming doors, and moving small objects. Maybe I just don't get it but I just cannot

detect the photons anywhere in the picture, coming or going. Nor do I see any squiggly

lines. Oh, I can certainly imagine it, but I cannot detect them and I have not yetsubmitted myself to let my imagination serve as a form of existence outside my body.

The illusion above demonstrates how the mind can get fooled. I challenge anyone to

look at it with without seeing a square. Perhaps a similar kind of illusion occurs with

our imagining the trajectory of photons coupled with the classical existential descriptionof light.

As animals we humans have evolved a way of gaining knowledge about the world so

that we can survive and make use of our knowledge. However, we evolved in a

macroscopic world where everything seems to have a cause and effect. The patterns we

think we see corespond to patterns we find in nature but we have a difficult time trying

to understand things not of our world (the subatomic world). As the biologist Richard

Dawkins observed, "We are not the only animals to seek statistical patterns of non-

randomness in nature." (Dawkins, 1998)

The Faraday effect


10/22

Many a scientist has fooled himself into believing that a magnetic field can change the

polarization angle of photons. This shouldn't surprise anyone, considering the

unexamined language of their definitions. For example, a definition from the Handbook

of Chemistry and Physics, the Faraday effect describes "the rotation of the plane of

polarization produced when plane-polarized light is passed through a substance in a

magnetic field. . . the rotation is proportional to the thickness traversed by the light andto the magnetic field."

It says nothing explicitly about a magnetic field causing an effect on light itself, yet it

does describe light as "plane-polarized". From such language many scientists think that

a magnetic field has the ability to shift the polarization angle of light while in flight.

This simply does not happen. For an example of how some scientists can get fooled into

thinking this, see Scientific American, July 1977, "Science and the Citizen," where you

will find this amazing statement:

"Polarized light often twists as it propagates through space, as a result of its encounters

with electromagnetic fields; this well-understood phenomenon is called the Faradayeffect."

Apparently they do not understand this phenomenon as well as they think. If light,

indeed, can twist in a magnetic field, we should have a way to measure it. The

experimental setup below illustrates how one can easily confirm or overthrow this view:

By aiming a polarized laser toward a polarizer filter and a photo detector, a voltmeter

indicates a reading whenever the detector "sees" light when both the laser and the

polarizer have the same alignment. If a magnetic field can twist the polarization angle of

the alleged light beam, the voltmeter should indicate a lower reading when the magnet

approaches the beam at location B. It does not! Nothing twists. No change of

polarization angle. However, if the magnet approaches the detector or the laser (at

location A or C) a dramatic polarization shift occurs. This happens because, as the

definition states, the rotation occurs when "passed through a substance." Note the keyword "substance." But the deceptive part of the language describes light as "passed

through" as if light actually traverses through it. Just this kind of language can easily

lead to misinterpretation. Since magnets can affect charged particles, it can affect the

electrons in the substance, thus creating the Faraday effect. Magnets never affect the

alleged light rays in free space, perhaps, because they do not exist.

If light does not exist, then why do people see light beams?

If you shine a light or a laser through a cloudy atmosphere, you can clearly see what

looks like a beam of light. But note that the illusion of the beam requires some material

substance for its apparition. The beam consists of millions of particle events that occurat the electron level of the atoms in the clouded atmosphere. Taken individually, we


11/22

have an event at the light source, an event at an atom in the air, and an event at your

eyeball. When taken in total, it gives the appearance of a trajectory. Again, the only

things we can detect amount to electron events (the measurement points).

To give another example of a similar illusion in a different media, think of dots moving

across a computer screen. Does anything actually move? No, because all that happensinvolves turning on and off pixels. It just seems as if something moves through a

trajectory. You cannot scientifically say that just because it seems to move, that it does.

REMOVING THE PARADOXES

There occurs a paradox when trying to explain a wave model of light when using three

polarizers. The problem begins by understanding the implications of polarized waves or

photons. The following illustrates a typical description:

"A sheet of polarizing film transmits all light incident on it at a right angle if the light is

linearly polarized along a certain direction in the film called the transmission axis

(hatching). This polarization state of the photon is represented by the wavy colored line

at the top [red]. The film blocks all light incident on it at a right angle if the light is

linearly polarized perpendicular to the transmission axis (wavy gray line at top). Now

suppose a photon is linearly polarized at some angle to the transmission axis betweenzero and 90 degrees (bottom). Then whether or not the photon will be transmitted is

indefinite; the probability of transmission is a number between zero and 1 (the square of

the cosine of the angles)." [description taken from Sci. Am., Jan. 1988, p. 48]

Notice the contradiction of the language"polarization state of the photon" but

represented as a classical Maxwellian wave.

The following illustrates what happens when using two polarizers:


12/22

Any individual light wave coming from an ordinary light source (sun, or light bulb) can

travel in any possible polarization angle at right angles to the line of propagation. The

total mixture of light rays constitutes unpolarized light. When a light wave hits the first

polarizer, it will either go through or not, depending on the wave's alignment with the

polarizer transmisstion axis. If the light waves get through, they all proceed at the samepolarized angle to the next polarizer material. Depending on the second polarizer's

transmission axis, some may get through or get absorbed. In an idealized state,

polarizers at the left give us a probability of 1. The polarizers at the right give us a

probability of 0. Eveything works fine with the classical wave theory of light so far, but

what if we introduce a third polariszer?

The three polarizer problem

If you add a third polarizer in-between two polarizers, the classical wave concept falls

apart:

Note that the example above describes the same experiment as the two polarizers

aligned at 90 except that here we indroduce a third polarizer between the other two,

aligned at 45. As unbelievable as it may seem, some light still gets transmitted through

all three. How can this happen if the two outside polarizers (according to the classical

model) blocks all waves?

This clearly demonstrates a paradox and shows why a transverse wave or photon model

(or any existential model) simply cannot account for the results.


13/22

However, if there occurs no waves and no particles, the paradox goes away. Imagine

that instead of propagating light, we have vibration events occurring at the light source,

the polarizers, and at the detector, and nowhere else. Nothing at all occurs between the

measuable events, no trajectories, no particles, no waves-- nothing. The illustration

belows shows what happens:

The "vibrations" occur only at the electron level in matter (marked in the illustration as

an x). Note that in order to have polarized light,you must have a polarizing material.

Instead of imparting polarization and transverse waves to light, why not attribute it to

the very polarizer material from where it occurs?

If, instead of describing the polarization angle of the alleged photon, and we limit

ourselves to only what we can examine (the molecule alignment in the polarizer whichdescribe the transmission axis, and an electron events) we need not think of a wave

traveling through space at all. We only need to describe what happens with our test set-

up. If we have an unpolarized light source, three polarizers and a detector, there will

occur a probability that the detector will sense an event between 0 and 1. And the

probability depends entirely on the properties of the materials in the experiment and the

alignment of the polarizers. In short, we simply do not need an independent

wave/particle model to predict what happens!

The Double Slit Experiment

Because of the length necessary to describe the double slit experiment, I won't go into

the details but you can find an excellent description of the paradox in The Feynman

Lectures on Physics (Feynman, 1963) (seeVol. 1, Chapter 37).

Briefly, the experiment describes an emitter, a wall with two slits, and a detector screen.

The thought experiment shows that a subatomic particle (photon or electron) seems to

behave particle-like when it passes through only one slit open, but wave-like with both

slits open. The paradox occurs when imagining what would happen if the experimenter

closed one of the slits as the photon (or electron) "flew" through space before it passed

through a slit. How can the particle "know" beforehand if it should act wave-like orparticle-like? It seems as if the particle has to know the future.


14/22

However, if you think of a measurement-only, non-trajectory model, the problem goes

away:

If light does not exist between matter events, then we have no paradox simply because

nothing passes through the slits. Instead, we can explain it as the source vibrating

(jiggling electrons) which in turn causes the electrons in the wall to jiggle, which in turn

cause the detection screen to jiggle its electrons (each sequence of event gets delayed

through time). The wave and interference properties occur entirely within matter at the

electron level (think of millions of electrons vibrating, like a 'wave' in a crowded

football stadium). If we had only one slit open, then the detector would behave as if it

received particle-like hits.

This model also works for individual photon events, excited one at a time and

accumulated over a long period of time.

Why do electrons behave like photons in the double slit experiment?

Electrons may behave similarly to photons but they do not behave identically. Textbook

descriptions attempt to confuse this issue by attempting to show identity through scaled

up defraction photos so that they appear the same. You will find electron microscope

defraction photos compared with X-Ray defraction photos (Wichmann, 1967). But if

you look closely at the experimental setups (which rarely get mentioned in the

textbooks), you cannot substitute an electron for a photon in either a defraction

experiment or a double-slit experiment and get the same results. Although experiments

with electrons have shown interference effects, the scales of the setup for an electronexperiment must occur at magnitudes smaller than setups for light.

"This experiment has never been done in just this way. The trouble is

that the apparatus would have to be made on an impossibly small scale to

show the effects we are interested in."

-Richard Feynman, 1963

We can detect electrons in free space because they have mass and charge. We know

they exist in free space because we can change their direction with magnetic fields.

Electron tubes in TV sets would not work if we could not do this. Because they have

mass, they add their mass to atoms, which we can weigh. Bubble chambers indirectly


15/22

detect them by ionizing the gas in the chamber. You cannot do these things with light.

Electrons also differ in their apparent slower velocity.

Speaking in quantum mechanical terms, however, electrons do not travel or move

through space either, although they can exist in space for short periods of time while

quantum jumping, or tunneling from one location in space to another. These quantumjumps give the illusion of a trajectory (like pixels turned on across a screen).

Although electrons do not exhibit identity to photons, they appear exactly identical to

each other. Unfortunately we have no way of tagging an electron. Unlike macroscopic

objects, we cannot mark one with a pen, or attach a tag, or tie a ribbon to one. In short,

we cannot tell the difference between one electron and another, and according to

quantum theory, not even in principle.

By using electrons in a double slit experiment, one might at first say that this has to

prove that an electron (which we admit can exist in space) must pass through a slit.

However, one can equally say that it does not pass through but rather "tunnels" fromone location to another. Since electrons appear exactly identical to another, no one can

tell the difference between an electron at location A from one at location B. I have no

right to choose only one frame of reference. I can just as well say that a different

electron at location B replaces the one at location A. Moreover, we have no way of

finding out whether it jumps directly from A to B or from a staccato of events in-

between.

In the double slit experiment, light and electrons behave similarly but with the added

ability that an electron can sometimes jump at locations between events.

Thus, even in a quantum description of electrons in a double-slit experiment does not

invalidate the measurement-only model.

Interestingly, if a light quanta occurs as nothing but a feature, or a vibration of an

electron (a soliton?), then one might say that a gamma event (classically called a gamma

ray) occurs as an electron, quantum jumping (with a delay equal to light speed), from

one location to another. Interestingly, the energy equivalence of a gamma quanta equals

the rest mass of an electron.

Does light gravitate?

Clearly, if gravity pulls on light, this would seem to prove the existence of discrete

electromagnetism. But does gravity attract light like everyday objects?

According to Einstein's thought experiment on gravity, he imagined himself in an

elevator feeling its acceleration upward. Einstein thought that since you cannot see

outside the elevator, you cannot tell the difference between the force of gravity or an

acceleration force (imagine the elevator in free space). Einstein proposed that the two

forces appear equal. Furthermore, if a "ray" of light entered the elevator parallel to the

floor, the light beam would appear to bend downward. This meant that light, if traveledacross a gravitational field, would looked curved to the observer.

In 1919, the astronomer Sir Arthur Eddington photographed stars whose field of vision

appeared close to the sun during an eclipse. He compared the photos with those of the

same stars taken with the sun removed. Eddington found the apparent location of the

stars had shifted, just as Einstein predicted and confirmed one of the predictions of the

general theory of relativity.

But notice that even though Einstein believed in the discrete existence of quantum light,

his description does not explicitly state that light gravitates. In his paper on The

Foundation of the General Theory of Relativity he states: "We easily recognize that the

course of the light-rays must be bent with regard to the system of co-ordinates..."

(Einstein, 1916) . But to an observer at rest, the light beam would appear straight. In

other words, Einstein gives a relativistic description, not a gravitating mechanism. The

description further gets exacerbated by illustrations that show the Einstein bend in an

exagerated way:

This typical diagram shows the light bending in a dramatic but inaccurate way.

Eddington measured a deflection of 1.75 seconds of arc (Einstein actually predicted .83

seconds of arc, but the measurement came close enough to confirm the theory). We can

forgive the artist's exaggeration, however, because one cannot draw the actual arc andsee it. The tiny angle, would result in, for all appearances, a straight line. Eddington's

photos also had to capture stars at the closest periphery to the sun.

I do not pretend to have a solution for how light gives this bending illusion, but I can

speculate:

Since Einstein's theory predicts a gravitational influence on the measurement of clocks,

perhaps electrons at the solar edge, shift their spin orientation accordingly when acting

as a reflector or defractor. How else can we think of curved space except for how matter

behaves in it? Physicists also know that electrons can pop in and out of existence, even

in a vacuum. In short, in order to observe this bend,you must have a mass to cause thedeflection.

Note also, that a pixel moving across a screen while you watched from a gravitational

well would also appear to bend even though we know the pixel does not actually move.

(In Einstein's thought experiment, imagine looking outside the elevator at a large TV

screen with a pixel trajectory instead of a beam of light).

Gravitational lens


17/22

Gravitational lensing can occur which can make stellar objects, (such as galaxies and

quasars), appear doubled, magnified or focused. This seemingly odd phenomon actually

implies a special case of Einstein bend, as described above, except that the deflection

occurs on both sides of a mass. For an illustration, see:

http://scruffy.phast.umass.edu/a114/lectures/lec24/node2.html

Again, in order observe an Einstein shift or a gravitational lens effect, there must exist

some material body to influence its relative observed position.

Black holes

In describing the effects of a black hole, Stephen Hawking writes that, "light cannot

escape, neither can anything else; everything isdragged back by the gravitational

field." (Hawking, 1988) [bold characters, mine].

But wait! If nothing can escape, ifeverythinggets dragged back, how can the

gravitational force, itself, escape to influence other stars and matter? Gravity, according

to quantum physicists also comes in the form of discrete particles called "gravitons"

which can create waves and ripples through space at the speed of light. How do

gravitons manage to escape black holes? Do you see the problem the language creates?

Perhaps we should question the existential claims of gravitons as well (please note that

no one has yet detected gravitons either).

Black holes describe, in effect, a dramatic case of the Einstein's theory of relativity. In

principle, it differs only in magnitude from the Einstein's relativity "bending" of light.

But this again must agree with either the relativistic effects, or with a mass-to-matter

influence, or both.

Since electromagnetic energy requires a mass particle event, we can speculate on the

mass particles themselves. Visible light requires an occurrence of an electron event (we

cannot deny the discrete existence of this mass particle). Could then a black hole

influence electrons in such a way as to either prevent their transmission of light or by

redirecting their influence inward, toward the center of the black hole, instead of

outward?

Again, I cannot answer these questions, but I can create concept models just asworkable as those who believe in the existence of light as a discrete particles. No one

has yet proved that light can gravitate, regardless of how many descriptions say that it

does. Beliefs, regardless of how many believers, do not equal proofs.

EVOLUTION THROUGH HISTORY

Looking back through the history of science, we can see how the evolution of the

understanding of light came about, the conceptual confusions that arose, and how the

information got transferred from brain to brain (a classic meme transfer, that with thevast documented history might appeal to those interested in memetics). From various
http://scruffy.phast.umass.edu/a114/lectures/lec24/node2.htmlhttp://scruffy.phast.umass.edu/a114/lectures/lec24/node2.htmlhttp://scruffy.phast.umass.edu/a114/lectures/lec24/node2.html

empirical experiments from Huygens and Faraday, it seemed clear that light behaved

like waves. And like all waves known to human comprehension, light needed a medium

to vibrate in. The scientists could not accept the idea of action-at-a-distance, so they

borrowed Aristotle's ancient concept called an "ether" to account for a hypothetical

medium that filled the void of space. They spent years searching for it but they could

not detect it. Later, Einstein showed that, through the principle of relativity, the conceptof an ether contributed nothing to the physics, and therefore we need not spend time

thinking about it. Physicists did not like the idea of losing the ether because it

introduced the idea that subatomic events do not behave like ordinary classical objects.

But this they had to do, if they wished to advance the state of physics.

Unfortunately for the believers of classical reality, things got worse. Not only did light

not require a medium to travel in, but some atomic particles, like the electron, seemed to

jump from one atomic orbital, in discrete steps, without anything occurring between.

The idea of sub-atomic trajectories made no sense in the quantum world, and the

physicists had to abandon classical trajectory motion.

"The motion of a particle cannot be described in the familiar terms of classical

mechanics, and both its position and its velocity are subject to a certain indefiniteness

(Heisenberg's uncertainty relations and Bohr's complementarity principle)." (Gamow,

1961)

"Classical physics is played out before an all-seeing eye. It has trajectories. We can

follow the motion of particles from moment to moment as they interact with each other.

We have to give that up in the quantum world. There are no longer trajectories."

(Polkinghorne, 1984)

To make matters worse, single particle events occur at random intervals. This

randomness does not happen like the randomness of a coin toss. In principle, if one

knew every physical property of the coin, a physicist could determine the outcome. In

other words, classical randomness has an absolute deterministic outcome. In quantum

randomness, no one can figure it out, not even in principle. Many physicists, especially

those trained in classical physics, could not accept the idea of indeterminate

randomness. Unfortunately, Albert Einstein could not accept quantum randomness

either and his intransigent beliefs outlined his barrier to further understanding. Along

with his fame and influence, so also went his classical reality descriptions of light.

Although Einstein helped advance the first steps of the quantum theory, he could notentirely let go of the classical world, and this, I think, gives reason why he could not

have postulated light in a non-trajectory way. His form of reality corresponded to

classical physics, just as his education taught him. Yet Einstein did understand the

problems of language when he wrote:

"When language becomes thus partially independent from the background of

impressions a greater inner coherence is gained. Only at this further development where

frequent use is made of so-called abstract concepts, language becomes an instrument of

reasoning in the true sense of the word. But it is also this development which turns

language into a dangerous source of error and deception. Everything depends on the

degree to which words and word combinations correspond to the world of impression."(Einstein, 1950b)


19/22

For this reason, I think Einstein, even though he understood the problems of description,

must have had such a deep belief in classical reality that it never occurred to him to

think of light in any other way. In arguments with Neils Bohr, he stated his famous line

about a god not playing dice. Also in a letter to Max Born, he states his belief clearly:

"You believe in the God who plays dice, and I in complete law and orderin a world which objectively exists, and which I, in a wildly speculative

way, am trying to capture. I firmly believe, but I hope that someone will

discover a more realistic way, or rather a more tangible basis than it has

been my lot to find. Even the great initial success of the quantum theory

does not make me believe in the fundamental dice-game." (italics, his)

-Albert Einstein, in a letter to Max Born, 7 Sept.1944 (Born, 1971)

Unfortunately, physicists, as all human beings, can fall prey to beliefs and faiths. Isaac

Newton had postulated the first ideas of relativity, but he could not advance the theory

as long as he held the belief of absolute time. And Einstein could not let go of his

classical descriptions to understand the implications of quantum mechanics, even in thelight of the success of the new science.

Most physicists do not concern themselves with the epistemological questions of

science. And as J. C. Polkinghorne put it, "Your average quantum mechanic is about as

philosophically minded as your average mechanic." (Polkinghorne, 1984). In the

language of quantum mathematics, the paradoxes do not appear. Physicists aim for

useful reliable predictions, and if their physics does not agree with common sense, then

it doesn't matter. But in ignoring the consequences of describing physical events in an

inaccurate way, it can lead the layperson and, indeed, other scientists, to wrong

conclusions. Who can calculate how many research dollars and wasted time came about

because of false beliefs?

To this day, we see descriptions of light that carry a mix-match of classical and

quantum descriptions which produce the very paradoxes that support an industry of

new-age books that get preached to the naive. Even the mathematical proofs of non-

locality by John Bell have him implying the existence of wave-packets and photons

where he predicts: "the signal involved must propagate instantaneously, so that such a

theory could not be Lorentz invariant." (Bell, 1987) That implication out of the English

language (not out of the math), produced new ghosts, and along with it, a generation of

believers who use science as a kind of religion. Alain Aspect and his colleagues tested

Bell's theory and showed that, indeed, Einstein's classical view fails and the quantummechanical description holds (Shimony, 1988). But included in the quantum

descriptions remained Einstein's discrete quantum of existence with Lewis' verbal

invention of photon (the ghost), all to avoid the Aristotelean abhorrence of action-at-a-

distance.

We now have a plethora of books that describe the "collapse of the wave function,"

"superposition of states," and Schrdinger's cats, all of which depend on some kind of

reality of energy existing between events. From collapsing wave functions, some people

see a "Consciousness creates reality" view of the universe.

If the phenomenon of light, indeed, acts like action-at-a-distance, then we have nocollapsing wave function! The wave function would simply occur only as the detection


20/22

itself. Period. Nor does it produce a nonreality universe, for we can measure things and

make use of them. Nor does it produce a necessity for a consciousness required reality

(unconscious instruments can measure things while we look elsewhere).

A MYSTERY REMAINS

If we gave a scientific description of only what we can measure in the quantum world,

we need not introduce unnecessary concepts. But even if we do so, we do not escape a

puzzle: If light does not exist between events, how does an electron event influence

another electron? Physicists have no problem describing quantum jumps at the scale of

atomic nuclei. But what about an electron event that occurs in a star, millions of miles

away, one that occurred millions of years ago, which influences an electron in the eye of

an earthly beholder?

The implications appear staggering, and I do not pretend to have an answer. It certainlydoes not conform to common sense. Regardless, we have not introduced a new mystery

but have only have eliminated the forest of other paradoxes so that we can see the

remainderwhich already occurs for quantum jumping particles. For even if we maintain

the idea that energy exists as a particle of existence, we have added problems such as:

How can a particle remain in a pristine state over such long distances? Why do these

particles not interfere with themselves in free space? And we would still have the

paradoxes of the double-slit and the three polarizers.

Perhaps our human nature bars us from understanding. We evolved as pattern

recognition animals. If we cannot see a pattern, we invent one to account for the

phenomenon. But if the quantum world acts through randomness, we will never see a

pattern (no-pattern = randomness). For even if we detect an electron event, we cannot

help but think of a determined actuality-- a reality. But by eliminating the old classical

way of describing causal events, and conform to the quantum description forallquantum events, including light, we drop the useless paradoxes, so we can attempt to

solve the problems relevant to the best physics.

Perhaps the answer will come with a better description of probability events. The

quantum world shows us that events occur out of pure randomness. There seems no

clear cut way to say that an electron at one point influences an electron at another point.

It occurs only in a probable sense. We assign a causal relationship only afterwe havemade our measurements, not before or during its randomness. In the language of

probability math, the mystery does not occur; but perhaps, yet again, our spoken and

written language creates unnecessary spooks and creates a barrier to our understanding.

Notes:

1. In this paper, I have addressed primarily the electromagnetic force because it

represents the best known force and the most viable link to human affairs. But the same

treatment can apply for any alleged massless particle, including the hypotheticalgravitons of the gravitational force and the gluons of the strong force.

2. In no manner do I mean to show that light cannot exist between events (I cannot

prove non-existence), only that the evidence of its discrete existence has not yet arrived.

I use a variant of"Occam's Razor" approach to the problem: the simplest description the

better, as long as it describes the phenomenon equally or more thoroughly.

3. Anyone can easily test the 3 polarizer problem by using 3 ordinary plastic polarizers.You can order polarizing material fromEdumd Scientificor get and old pair of

polarized sun glasses and cut the plastic lens into three pieces.

4. The children's poem derives from aWilliam Hughes Mearnsrhyme inAntagonize,

1899: "Yesterday upon the stair, I met a man who wasn't there. He wasn't there again

today, I wish that man would go away." Many other derivations of the rhyme exist. The

version I used came from Robert Anton Wilson.
