Ah the humble photon. The literal essence of light itself. Hard to imagine what life, or anything for that matter, would be without it. It's a pretty interesting particle in that it has no mass, and travels very fast.
We know that like sound, light travels in waves. Depending on the speed of the wave, the photons manifest themselves as visible light, UV (Ultra Violet) radiation, and radio among other things. Pretty neat for such a tiny thing.
Here's where my problem starts. The common idea is that light is emitted. What I mean by that is that when you turn on a lamp, photons shoot out at you and your eyes interpret them accordingly. But wait a minute. Didn't I just say that light travels in waves just like sound? Sound isn't emitted, it's a vibration through a medium like air or water. Why does light get to be different?
I propose that light is not in fact different from sound, and is in fact a vibration through the medium of photons. In this scenario, the photon must therefore be literally everywhere in the universe.
How can light travel in such a clean sinusoidal wave that is emitted? A vibration creates such a wave structure by default and its very nature.
On a basic level, if photons are emitted rather than vibrated, then where do they come from? Isn't it convenient that light sources always have the correct amount of photons in them such that they always operate the same? Seems much more likely that light sources just vibrate at a particular frequency based on the properties of the material, and/or power source.
Why is it that when a truck drives by, you can pick it up on low frequency radio receivers? What about random radio noise? These are easily explained if an object or objects are moving within a substance that they can effect. I would expect this photon medium to be much like a swimming pool full of kids. Lots of small ripples going every which way seemingly at random, with some larger more pronounced ones resulting from a larger disturbance.
Magnetism is a result of action by photons. We use electromagnetism for our phones, radios, and at least part of our cars, but your typical fridge magnet also uses photons. Photons everywhere might explain why a magnet feels a bit like a vacuum cleaner. Put your hand on the nozzle and the pull is much stronger than even a short distance away. A permanent magnet therefore seems to be pushing photons out one end, and subsequently sucking them back in the other.
You could call photon movement from a magnet the equivalent of direct current (DC) in electrical terms, and a radio transmitter a generator of alternating current (AC).
The vacuum analogy also suggests that there is a distict density of photons (photons per cm3) but the question is what is that density, and whether they behave like a gas (compressible), or a liquid (non-compressible).
I find all too often that it is very easy to overcomplicate something that really isn't complicated. There is consistency in this universe, and I feel comparing the nature of light to that of other wave phenomena is a much better place to look to explain things.
