The Length of the Photon
Would it be helpful to imagine the photon as a wave thread connection (physical) from the source to where it is absorbed or entangled again? Between the source and destination (entanglement) the photon wave has small amplitude with a huge period to conserve the energy. This long period (threadlike) is perhaps how huge distances can be trans versed with no (little?) loss of total photon energy.
If it entangles with something then it collapses from the source to its source determined wavelength and amplitude again at the destination. But before the entanglement it is stretched out with immensely large period and tiny amplitude not entangled.
Given this idea, the length of a photon is perhaps the distance from the source to the place where it entangles, and only when it entangles does it express its source determined wavelength.
When a double slit is in the photon path, the stretched thread (which is still connected to the source) goes through each slit at a different time. This time difference is related to the small distance between slits. This time amount would perhaps be too small to measure.
With this view the photon does not interact with itself nor does it pass through both slits simultaneously.
Its interaction or entanglement with the final destination is where the characteristic "interference" pattern is seen caused by the rapid oscillation of the photon thread oscillating from one slit to the other. The oscillation is due to the 50% chance that it goes through one slit.
In this view the photon does not leave the source and arrive at entanglement.
The source and destination are connected until it entangles (almost instantaneously). The long period energy then collapses at entanglement with a source determined wavelength (reclaiming the thread energy) and producing the interference pattern because it went through different slits at different times. The long period wave has a vector force toward the destination.
So the length of the photon would be the distance from the source to the destination.
The form of the photon energy would have 2 forms. Source determined wavelength and thread wavelength (huge period with tiny tiny amplitude). The further away the destination, the lower the amplitude of the wave and the longer the wavelength, until entanglement.
If the wave lost any energy into intermediate space, the source determined wavelength upon entanglement would be red shifted.
Maybe the stretched out photons are what “dark” matter is as all space is filled with light. A very small proportion of it becomes entangled with matter. Like sunshine.
This concept becomes more interesting when one considers that the form of photonic energy is probably helical. Between the source and the destination the helix approaches straight line proportions.
Entanglement requires the recoiling of this photon "spring thread". The entangled state being the source determined wavelength.
So perhaps the length of a photon is the distance between the source and the destination. Does this idea remove the enigma? Is there a weakness in this model? Does it affect expanding universe models?
Are these ideas admissible in any way into consideration?
