So if a single photon is emitted and it travels as a wave, then it should lose its energy by distance squared. But how can it possibly do it? -its a single photon, so its intensity cannot really change, can it? What - you will have a half of photon? What does that even mean? How can it be like that. .. it only seems that it may loose energy by decreasing its frequency .. but it doesn't seem to be the case.
.. we do see redshifts and they become stronger as stars/ galaxies are further from us and it would be consistent wit this as the further it travels- less energy (more points in space to cover) - lower frequency. .. and it wouldn't require expanding universe and something like that.. witch is kinda big deal, id its right - witch it shouldn't be, because the rate at witch such a decrease in wavelength would happen .. should be way more faster. If it does happen at all.
now. one answerable question might be : how fast would such a decrease in frequency happen? (the one photon expansion/ decrease in energy per point as the points get more in space)
another - can it even be like that?
- how DOES single photon propagate in space and why doesn't all EM waves travel in the same way even if they are one as a group - sooner or later there will be just one photon per point (whatever that means) and continue to propagate just like a single photon from the start.
And the answerer cannot be just like : they don't travel as waves. They must, because then there would be quite some more problems.
oh, I have so many questions about photons. I don't even know where to start. :O
oh, wait - i just started.
I just cannot get my head around it. Photons are going to drive me crazy!
