This is standard physics teaching as far as I am aware
Quote from: mxplxxx on 23/02/2019 23:20:56This is standard physics teaching as far as I am aware Your awareness is either faulty or not suported by common sense. Consider a point source of photons. If a particular photon is duplicated in all places in the universe where is can possibly currently exist, then placing a detector anywhere will attract all the photons. Don't look at the sun.
the likelihood of all of you spontaeously materialising on the far side of the moon is of no practical consequence
It's an interesting point. I've lost my lecture slide about the natural rate of DNA transcription errors but it runs into zillions per day. Most are harmless or ineffective but the adjoining "normal" cells have to somehow prevent the defective ones from multiplying. One oddity is the female breast, which may have to change its function several times at (relatively) short notice, so my hypothesis is that it is more tolerant than the rest of the body towards "deviant" behavior and may permit the growth of tumors that would be killed by the immune system if they occurred elsewhere. A complete digression, but an interesting one.
There is also the fact that the breast may have to switch off at least part of the immune system to enable it to manufacture something that is meant for a different body.

Is it possible the photon has attributes that are immediately transferred to the receiving particle, much like an event in a computer program immediately updates the status of an affected object.

One last try at punching smoke. The ultraviolet catastrophe was solved by Planck introducing h. Otherwise the classical theory would still predict the energy approaching infinity at shorter wavelengths. https://en.m.wikipedia.org/wiki/Ultraviolet_catastropheIf you still don't understand then there is no hope.
He assumed that a hypothetical electrically charged oscillator in a cavity that contained black body radiation could only change its energy in a minimal increment, E, that was proportional to the frequency of its associated electromagnetic wave.
Despite doing quantum physics for money for over 50 years, I've never encountered any "controversy" about the dimensions of h. Only priests, politicians and philosphers argue about the bloody obvious.
While I am about it let me tentatively suggest based on the above that h is in fact Energy (E), not Action.
It is my guess then that E in E=hf is only an approximation
It is hard to see how such a thing can exist.
If photon has momentum, why navy laser weapons have no kinetic impact?
