Photon is strength which is emitted away from the particle or absorbed by the particle.
- It's impossible that a particle emits photons infinitely.
- It's also impossible that a particle absorbs photons infinitely.
The emitting ends to the decay of the particle. At the the end the whole particle has decayed and ceased to exist.
This can be observed as a loss of matter.
The absorbtion ends "never", but as more photons are absorbed, the propability grows that the opposite reaction to decay occures; Matter is created.
But what exactly causes the photon to be emitted?
First we need to understand; "What is photon." We know it has a fixed speed and it goes straight line in vacuum.
It's also said that photon has no mass, though mass is energy and photon has energy. This energy is defined through wave-length and/or frequency. https://en.wikipedia.org/wiki/Photon_energy
Photons being massless, the notion of "photon energy" is not related to mass through the equivalence E = mc2.
That this is obviously contradiction, doesn't seem to disturb anyone. Though Galileo said allready; http://www.conservapedia.com/Galileo's_maxim
"two truths can never contradict each other"
1.the Photon has mass
2. Energy doesn't have mass.
As the opposite for option 1. has been verified with measurements, the Option 2. must be accepted as truth.
This frees us from a lot of debates;https://en.wikipedia.org/wiki/Mass_in_general_relativityhttps://en.wikipedia.org/wiki/Mass_in_special_relativityhttps://en.wikipedia.org/wiki/Invariant_mass
But we can simply shut down this as a meaningless debate, If we just forget the mass!
What then makes the difference between matter and photon?
We have two options; https://en.wikipedia.org/wiki/Time_dilation
The time dilation is said to be verified by the measurements with atomic clocks; https://en.wikipedia.org/wiki/Atomic_clock
But these clocks seems to be even temperature sensitive!
So is time temperature sensitive? But what is temperature other than movement/velocity. And what is Thermal expansion other than increase in length. And greater lenght obviously takes more time to travel if the speed is constant. So I think time is also constant; i.e. there is no time dilation.
Thus length contraction is the only think we would have; and this reveals us the possibilty to understand the nature of photon.
Photon is strenght(massless energy) without a volume. Matter is energy with volume. So if you push the matter to zero volume, it's forced to decay away in photons. This will happen for any material which reaches the speed of light. The photon will be emitted on the opposite direction to the movement. This means that photons are always emitted to the opposite direction to the movement. If the particle is hold in place through magnetic interactions (in solid matter) then this movement happens back-and-forth and the photons are thus emitted in all directions.
When a object of solid matter is moving all the particles are emitting more photons in the opposite direction to the movement compared to the other directions. This means that particles in leading edge of the object is emitting photons inside the object, and these photons can be reflected through the other particles of this object.
...At this point it might be necessary to study this lection of QED from Richard Feynman, 50 min forward, The punch-line is at 55 min ; "You get nothing"https://www.youtube.com/watch?v=eLQ2atfqk2c&list=PLkLaruvqdNx8xJOZ1HXqtSbsPQtdulSm-&index=1
This reflection is dependent on the material thickness, and some particles get simply nothing from the other particles, though they emit as the others, they get nothing by them self. These particles are located in the Trailing edge of the object, and thus they decay away.
This can be proven also by another aspect; the particles in leading edge should receive more photons, and thus there should happen material creation. This can also be clearly observed on the moon; the lunar north-pole on the Earthside has an area with practically no craters.https://en.wikipedia.org/wiki/Moon#/media/File:LRO_WAC_Nearside_Mosaic.jpg
This is the part which constantly receives more light (reflected from earth) than any other part of the moon, but it's also on the Leading edge compared to the orbital movement and to the movement of the whole solarsystem.
This writing starts to get quite long,,, I stop here now., but if you think this is something new, google
"Roger Bacon Opus Majus On the multiplication of species" Here the word "species" means photons and he explained on year 1267 allready very correctly how everything is from light. He also explained optics with about same level as Newton did, only 400 years earlier...
