Thought Experiment – Photons up Close

Recently I published a paper on radio frequency photons:  Thought Experiment- Photons at Radio Frequencies in which I described a photon from the time of emission from a radio antenna as it propagated outward until it separated into photons and was later captured by an antenna.   

What I found was that the photon started as a whorl or vortex, if you wish, traveling initially in patterns of counter-rotating fields that eventually became identified as individual photons.  These whorls/vortexes have a specific size (diameter) and energy defined by the frequency of the emission.   A point on the rotating photon describes sinusoidal patterns that fall behind the photon in the classic electromagnetic patterns.   The thought experiment allowed me to calculate the maximum diameter of the photon at 105 mhz to be about 0.9 meters and a visible-light blue photon to have a maximum diameter of 143 nm.

Having learned from that, I decided to do some more thinking about photons in general.  What applies at radio frequencies should also apply to photons of light and higher energies.   It occurs to me that we can learn a lot about photons by experimenting with them at radio frequencies.   We know that radio signals diffract around sharp structures and even exhibit double slit diffraction if passed between sets of tall structures with sharp edges.   I don’t know of any single-photon experiments at radio frequencies but I suspect that the results would be the same; diffraction still occurs in which the photon interferes with itself.  

Having looked at it from a whorl or vortex photon standpoint (as opposed to a wave standpoint), it is easy to imagine a photon nearly 1 meter in diameter passing around both sides of a telephone pole or being pulled around a corner of a building as one edge drags on the sharp edge there.    

The same thing should happen to a red, blue or green photon encountering superfine wires or sharp edges of a razor blade or slit.  

Not having the equipment nor the results of any such experiments at radio frequencies, I’m going to move this into a thought experiment and follow a photon up close, drawing on the earlier radio frequency thought experiment and adding details that agree with what we know about light photons and see where we go.  In this case I’ll consider a 450 nm blue photon.   I mention a blue photon only to help differentiate it from a radio frequency photon in the following discussion.  It doesn’t matter what it is, they should behave the same.

Blue Photon

 by James Tabb  (ripples greatly exaggerated)

A blue photon is emitted when a source (the emitter) such as, for example an electron that changes energy levels from a higher level to a lower one, shedding the excess energy as a photon.     I imagine it like a sudden elastic-like release of energy in which the energy packet moves away instantly to light speed.  If the packet follows Einstein’s equations (see graphic below) for space distortion, then a blue photon is immediately flattened into a disk of 143 nm diameter (see graphic above) because the lengthwise direction shrinks to zero at velocity c.   (This diameter was derived as d = λ/Π from my previous article and depends on the wavelength)

In my description of a radio photon, the energy in the packet is rotating around the perimeter of the packet at c as well as moving away from the emitter at c.   The limit of c in the circular direction also limits the diameter of the packet.

I can picture photons that slosh back and forth left to right or up and down or in elliptical shapes.   All of these shapes and directional sloshing, and rotation are equivalent to various polarization modes – vertical, horizontal, elliptical and circular.   I can also imagine that these shapes/polarizations are created as photons are beaten into these modes while passing though lattices or slits that encourage the photon to go into one mode or the other or to filter out those going in the wrong direction.   I can begin to see that when photons at light wavelengths are thought of as rotating whorls, it becomes easier to think of how this all works.   None of the modes involve back and forth motion because to do so, the portion going backward would never catch up to the forward mode or it would exceed c.   

Now that the photon has been emitted and begins its flight, we are purely in a relativistic mode.  Einsteins equations for space distortion and time dilation tell us that the path in front of the photon shrinks to zero and the time of flight shrinks to zero as well.   This has always raised a troubling problem because we know that some photons take billions of years to fly across the universe and move about 1 nanosecond a foot of travel.  

In order to resolve this problem, I’m now imagining an experiment in which an excellent clock is built into a special photon that starts when the photon is emitted and stops when it arrives. (Good luck reading it, but this is only a thought experiment, so I’m good to go.)  Perhaps the path is a round trip by way of a mirror or some sort of light pipe such that a timer triggered at the start point also stops again when the photon comes back. If the round trip is about 100 feet then you might expect the timer and the photon’s clock to both register about 100 nanoseconds more or less for the trip.

When the experiment is run, the photon’s clock is still zero when it arrives and the other timer does indeed read very close to 100 nanoseconds. The photon seems to have made the trip instantly whereas we measured a definite trip time that turns out to agree with the velocity of c for the photon throughout its trip.  I decided that is the correct outcome based on the time dilation equations of Einstein when using velocity = c. 

So we see that Einstein’s time dilation equation applies to the photon in its reference frame, not ours.  There are nuances here that we should consider for the photon:

(1) Since the distance the photon travels is zero, the time it takes is zero as well.  That is why the photon’s clock does not change.   Therefore, I claim that the space/time jump is instantaneous and therefore the landing point is defined at the moment the photon is created regardless of the distance between the two points.

(2) Since we know that the photon packet cannot go faster than c and by experiment, it does not arrive faster than c, it appears obvious to me that the instantaneous space jump is not completed instantly, only defined and virtually connected.  I visualize that for one brief moment, both ends of the path are (almost) connected; emitter to photon, photon to its destination through a zero length virtual path. The photon does not transfer its energy to the destination at that moment because the path is only a virtual one.

(3) I visualize the photon’s forward path shortened to zero, an effect which has everything forward to it virtually plastered to its nose, like a high powered telescope pulling an image up with infinate zoom capability.   All of space in front of it is distorted into a zero length path looking at a dot, its future landing point.   

(4) The photon immediately moves away from the emitter at light speed. As it does so, the path beside and behind the photon expands to its full length (the distance already traveled, not the total path) with a dot representing the destination and the entire remaining path virtually plastered to its nose.   A zero-length path separates the nose of the photon from the landing point. The path already traveled expands linearly as the photon moves away from the emitter along that path at a velocity of c.

(5) I claim that the photon’s zero-length virtual path is effectively connected all the way through, including all the mediums such as glass, water, vacuum, etc.  However, the photon only experiences the various mediums as the path expands as it moves along.  I make this claim because it explains all of the quantum weird effects that we see described in the literature and thus appears to be verified by experimental results.  My next paper will detail this for the reader.

The landing point only experiences the photon after the entire path is expanded to its full length. In the example, the starting and ending points are 100 feet apart with a mirror in between, but the entire distance between (for the photon) is zero and the time duration (for the photon) is also zero (with maybe a tiny tiny bump when it reverses at the mirror). For one brief instant, the emitter is connected to the photon and the photon to the mirror and back to the timer through two zero-length paths, but it is a virtual connection, not yet actually physically connected.

The mirror and landing point remains virtually attached to the nose of the photon which moves away from the emitter at light speed, c. The photon’s clock does not move and the photon does not age during the trip, but the photon arrives at the timer after 100 nanoseconds (our time) and transfers its energy to the timer’s detector.

(6) I also claim that all the possible paths to the destination are conjoined into one path that is impossibly thin and impossibly narrow, much like a series of plastic light pipes all melted into one path that has been drawn into a single extremely thin fiber.   This is a result of the fact that the distances to every point in the forward path is of zero length, and therefore all the paths are zero distance apart.

In effect the entire path is shrunk to zero length at the time of emission due to a severe warp in space. Zero length implies zero duration for the trip as well, and the photon is in (virtual) contact with the mirror (and also with the finish line) instantly, but the space it is in expands at the rate of c as it moves away from the emitter.

Everything in front of the photon is located as a dot in front of it. It experiences the mirror after 50 nanoseconds of travel time. The reflected photon is still stuck to the finish point as the space behind it expands throughout a second 50 nanosecond time lapse and the finish line timer feels the impact at the correct total 100 nanosecond time while the photons clock never moves.

The major point learned in this thought experiment is that the photon’s path and landing point is perfected at the time it is emitted whether the path is a few inches or a billion light years long due to the relativistic space/time warp. This is a major point in explaining why quantum weirdness is not really weird, as I will discuss later in a followup paper that clarifies the earlier posts on this subject.

Wormhole Concept 

I visualize the photon as entering a sort of wormhole, the difference is that the photon “sees” the entire path through the wormhole but does not crash through to the other side until the wormhole expands to the full length of what I call the “Long Way Around (LWA)” path. Unlike a wormhole, it is not a shortcut as it merely (as I call it) Defines the Path and Destination (DPD).  This concept also applies to any previously described wormhole – see my previous paper, Five Major Problems with Wormholes

Here is the important point: The photon in this wormhole punches through whatever path it takes instantly at the moment of creation and defines the DPD. Every point in the DPD is some measurable LWA distance that is experienced by the photon as the path expands during its transition along the path. The LWA includes any vacuum and non vacuum matter in its path such as glass, water or gas.

So now we have a real basis for explaining why quantum weirdness is not weird at all – it is all a matter of relativity, as I will explain in my followup paper.

Speed of light regulated

Speed of light regulated

What determines the speed of light? We know that it is a limiting factor for all physical objects. We have heard it time and again – nothing goes faster than c! Nothing.   Can we determine why it is regulated to c?  I think we can.  It is all a matter of relativity.

Photon in FligthSuppose we consider the idea that the photon is disk-shaped due to space distortion.  (See figure at left) The photon is traveling at the speed of light and the space distortion equations tell us that, from our perspective, the photon’s dimensions in the direction of travel are greatly shortened, essentially like a very thin pancake set perpendicular to the direction of travel.

We know that the photon is a ball of energy related to its frequency and we know that the frequency determines the color of light that we can actually detect with our eyes. A blue photon has both a higher frequency and energy than a red photon. All the energy is confined to that flat pancake moving along at the speed of light, c.

Now we come to a slight separation from the earlier argument that the clock of the photon is stopped and nothing wiggles in a photon with a stopped clock. That is, in my opinion, true for the photon, but we are talking about the photon here from an observer’s point of view, not the photon’s perspective.  From the observer’s point of view, the photon moves with measurable velocity, measurable frequency, measurable energy, and thus potentially real live vibrational modes as seen by a clever observer. The time experienced by the photon is still zero from start to finish of its journey, but the observer still knows it is moving at a particular pace and also vibrating as it goes.

The photon cannot vibrate in the front to back direction because to do so implies that the vibration mode that goes toward the back lags behind and then it could never catch up without exceeding the speed of light. This implies that the photon vibrates from side to side or possibly either way around the rim of the disk and never front to back (well, maybe a very little, as explained later). The ripples in the disk are shown greatly magnified in the figure of the photon in flight above. Vertically polarized photons vibrate from rim to rim in a vertical fashion, horizontally polarized vibrate side-to-side and circular polarized photons vibrate around the rim, to and fro, and can even be lopsided a little producing an elliptical polarization.  These types of polarization exist in our real world and we can separate photons with various filters. prisims, and crystals.

Now let us suppose that we consider the vibrational modes of the disk in a little more detail. It seems that any vibration would cause at least some ripples along the disk, and that these ripples must involve at least some bunching of energy producing some motion front to back. Suppose these ripples are constrained to some minimum amplitude in order to even exist.  Could it be that these ripples actually limit the speed of the photon to some factor that actually defines c?   They can.

In other words, if the speed of the photon were to try to increase beyond the speed of light, as seen by our (any) frame of reference, the continuing shortening of the disk would reduce the amplitude of the ripples and potentially slow the photon back down to a speed where the ripples can still exist in our frame of reference. This provides a theory of how the speed of light is established and limited to a particular speed, “the speed of light”, for a photon. The speed of light is about 299,792,458 meters per second, usually symbolized by the letter “c”.

My thought is that when a photon or other particle is emitted, it probably takes off at the highest possible speed that is limited by the speed at which it can still maintain vibrational modes that can exist within an observer’s frame of reference. This is the speed of light as we know it and the regulator is the relativistic shortening of the disk in the direction of travel as seen by the observer. This shortening reduces the amplitude to a point that is sustainable for the energy it contains. If a photon can vibrate longitudinally, it would still be limited in amplitude to the size constrained by the disk in the same way described above, essentially very little, and regulated by the speed. The photon will always go at the maximum speed it can maintain (and no faster) within a given frame of reference. 

Why photons all travel at the same speed 

So why do all photons travel at the same speed?  Even for two observers traveling in differnt directions both measuring the same speed for a photon crusing by?  First lets consider some facts:  Blue light has a frequency, f, entered on 7.88×10^14 HZ and a corresponding energy e of 5.22 10^ -19 Joules. Red light has a frequency centered on 3.79×10^14 HZ and a corresponding energy e of 2.373 x 10^-19 Joules. Since they have different energies and different frequencies, would they not reach that equilibrium at different speeds?

For the answer, consider this:  The energy and frequency of all photons are related to a simple constant, e= hf.   Where h= Planck’s constant= 6.6262*10 ^-34 J s (Joule second).  So the relationship of the energy of photon to its frequency is a constant.

Or put another way, h = e/f for all photons. The ratio of the energy of a photon to its frequency is a constant for all photons. Thus we can see that the sustainable amplitude is somehow related to h and all photons are regulated to the same speed, which we measure as c in any frame of reference.   For example, if you divide the frequency into the energy for the blue and then the red light photons above, the ratio comes out the same.   The result is h, a constant for all photons.   These relationships are well known in the physics world.

However, the frame of reference is a key element, which means that the regulation to c takes place in any frame of reference because the shortening of the disk is related to the speed within the reference of the observer (any observer and all observers), and thus become regulated to c in all frames of reference. If the frame of reference were within a spaceship traveling at near relativistic speed and attempting to measure the speed of a photon going in its direction, the photon’s speed would still be c in respect to the spaceship. The length contraction relative to the spaceship would just be enough to regulate the speed of light measured by the spaceship to agree with the speed observed on earth.

There is a little of cart before the horse-trading going on here. The equations for space distortion and for time dilation both involve the square root of a term that would be a negative number if the photon exceeded the speed of light. In order for us to consider that the photon might even try to go faster than the speed of light, the equation would need some modification to make things right. It might well be that in order for the photon to reach c it might initially slip into “superluminal” speed, but it would quickly be brought back to within the speed bounds by the disk shortening along the path of flight and the reduction of the amplitude of the energy waves in the disk, the shortening taking place in the frame of reference of the measurer/observer.  Even when there are no observers and no measurement taking place, the photon is not alone.  Other particle exist, even in a vaccum, virtual particles for example.  These make up a frame of reference too, so the photon is always locked in to c. 

All photons strive to go faster than c all the time, but are held back by the relativistic effect of space shortening’s effect on the need to vibrate.

This latter discussion begs a new question. If the vibrational modes could somehow be frozen so that they do not need to vibrate in flight as we observe them, could they then travel at an unregulated speed beyond the speed of light? Consider a particle that starts out at absolute zero. In that case all the parts are locked together and nothing moves and therefore has no vibration to sustain. What is to regulate the speed of that particle? Can we then reach superluminal speeds for such a particle?  I don’t think so because to get it up to speed, energy must be applied.  In the case of a photon, the energy comes from the change in states of an electron around an atom or a collision of some sort that generates a photon.  Once we have energy for a massless particle, it has to cruise along at c.

It may be possible that a photon in flight passing thorough from another dimension/universe might have motion relative to us moving so fast that there is no effective vibration taking place during the time of its passage, effectively frozen during its passage.   Such a particle might zip by at superlumal speed.  Of course we would never know it passed unless it hit something on the way.  Then we would have a mess.  

Physicists call hypothetical particles that travel at superlumal speeds tachyons, (hypothetical so far, that is).

There is one other consideration that acts as a speed regulator.  Something I hinted at above.   c is the speed at which the time and distance experienced by a photon reduces to zero.  I stated that a photon always strives to go faster than c.   Each time it does, it slips into imaginary time and pops back to c, and has to stay there.   Look at it another way.  The photon traveling at c arrives the instant it leaves (from the photon’s perspective).  If it went any faster than c, would it arrive before it left?  I don’t think so and so the photon cannot go any faster.

Hopefully I’ve given you something to think about.

Random Thoughts About Relativity

Facts About Relativity  

In order to introduce some of my ideas, it will be good for the reader to become familiar with some of the weird behavior of particles traveling at very high speed, high enough to invoke relativistic effects.

As seen by a stationary observer:

1) The closer a moving object gets to the speed of light, the slower its moving clock gets.

At the speed of light, it is zero – to the moving object, everything is simultaneous.  Start, Splat. The moving object sees the outside world as distorted, getting shorter in length, and at c, the length from here to there is zero, no matter how far the stationary observer measures it.  Photons live in a go-splat world.

2) The closer a moving object gets to the speed of light, the shorter its length gets.

At the speed of light, it has zero length to the stationary observer, but normal length to the moving object.  Everything seems normal to the moving object  until it gets to c – the problem for the moving object at c is that there is no time to seem normal – everything is instantaneous.

3) The closer a moving object gets to the speed of light, the larger its mass gets due to kinetic energy increase (for objects that have mass).

At the speed of light, an object with mass would have infinite mass.   This rules out object with mass ever getting up to c.  Photons do not have mass so they can move at the speed of light.   Nothing with mass can go that fast.

4) The closer a moving object gets to the speed of light, the more energy you have to use to get it there.

You have to give more and more energy to the object to get it  closer and closer to the speed of light. Energy equals mass times speed of light squared.  At the speed of light, the energy required is infinite.  You can never push an object with mass that hard.

What is the equation that describes the way in which time slows down as you approach the speed of light?

The equation is known as the time dilation equation and is:

Δ t = Δ T/ √[ 1 – (v/c)²]    Time dilation

Where  Δ t is the moving object time ticks and Δ T is the stationary object time ticks, v is the velocity and c is the speed of light.

When the velocity approaches c, the term v/c becomes very close to 1 and then the term Δ t becomes very large because the right side is divided by a very small number approaching zero.  This means that the distance between clock ticks gets very long for the moving object.   Time begins to stand still as it reaches the speed of light because the distance between tics becomes infinite.

What happens to space (in direction of motion)?

Δ x = Δ X/√[ 1 – (v/c)²]      Space distortion

Where  Δ x is the ruler mark as measured by the moving object and Δ X is the ruler mark as measured by the stationary object.

When the velocity approaches c, the right hand term approaches infinity.  essentially, a unit measure, such as an inch for the moving object would stretch millions of miles as measured by the stationary object at speeds near c.  

conversely, a foot long ruler moving near c would be invisibly short as seen by the stationary object – a term called foreshortening

Conversely again, the stationary object would seem impossibly close and impossibly short to the moving object near c.  At c, neither could see the other even with the best of instruments until they collide, which would be instantaneous for the moving object.  (To do so would imply that the image was moving faster than c.)

 So someone (very small and massless) sitting on a photon would think they see time normally, but the time of flight would seem to pass instantly from time started to time finished because no time would elapse (Δt very large).   Of course there would be no time to measure time (or even think about it) because the photon would instantly hit the other end of its path, no matter how far away that is.

Someone sitting and watching nearby would see time normally (from their perspective), but in their case, ΔT would be very short (time interval ticks near 0) and they would seem to age quickly compared to the someone riding on a photon.

The total time of flight might seem 100 years to an observer, but seem instantaneous for one traveling at the speed of a photon. The observer would age instantly according to the one moving fast, and the observer would think the one moving quickly didn’t age at all.   Weird isn’t it?  Weird but true.

Similarly, distance gets shorter as an object approaches c as seen by the observer and longer for the observer as seen by the object that is moving fast.

In other words, the time that passes in one time frame (Δ t) is the time that passes in another (Δ T) divided by the square root of 1 minus the velocity squared divided by the speed of light squared.

Enough of this – keep in mind that photons don’t have time to age, and photons arrive the instant they are emitted.  A photon emitted in the furthest star that we can see by telescope arrives the instant it is emitted.   (From the photon’s point of view).   They live an instantaneous “go-splat” life.

From our point of view it may have taken billions of years to get here.  Both viewpoints are valid.  That is the weird nature of relativistic speeds.  Time and space are distorted. 

One last thing:  Effect of speed on atoms:

Atoms are flattened in the direction of their motion.  Normally about 10 -8 cm in diameter they change from a sphere to a flattened disk as they approach the speed of light (from our stationary perspective only).

Particle accelerators have to be designed to account for both time dilation and space contraction in order to work. 

Atoms have mass so they can never reach the speed of light, but particle accelerators push particles, including atoms, to very high speeds that require design changes to keep them on track around their path – changes that involve the equations above.

Next – some of the quantum weirdness explained, example by example from the earlier posts.
