Photons and electromagnetic radiation
Thermal radiation is a common form of electromagnetic radiation. It is radiation that an object emits due to the temperature difference between the object and its surroundings. Heat is simply entangled information within a system that seeks to escape, just because that is the most probable development. Simply entangled thermal information more easily engages with simple structures and therefore moves away from more complex structures. See also section 6.21 on heat and superconductivity.

EM radiation, EM wave -> a stream of photons in coherence/superposition
When a single photon is emitted/created, for example, by the fall of an electron to a lower shell within an atom, that new photon can distribute its information freely in all directions except towards the source with which it is entangled. Consequently, as long as there are no disturbing influences from the environment, it will spread in all conceivable directions until a collapse occurs, and all the photon’s information is transferred.

In a continuous stream of photons, there is an influence from the environment, namely, the photons in front of and behind a specific photon. These make it much more likely that the distribution of information occurs in the same direction. In other words, they move in the same direction because probability ensures that the vacant spots are filled. A stream of photons is interconnected and behaves like a wave. If the photons follow each other quickly, it results in EM radiation with a high frequency. With these rapidly succeeding photons, the probability that everything moves in the same linear direction is greater than in the case of a greater distance between photons. High probability means high energy (see our sections on energy 6.15 and 6.16).

Photons in series with each other, as well as photons parallel to each other, form a coherent quantum system. They form a wave. They are in superposition with each other. In other words: EM radiation is a bundle of probability distributions.

EM radiation represents energy
Electromagnetic radiation is emitted at various frequencies by its source. A high frequency corresponds to high energy. In terms of relation physics, energy is the amount of probable changes in the system (in this case, EM radiation). The quantum system of EM radiation is a probability distribution with a probability density, indicating the spread of probabilities. EM radiation with high energy density exhibits a high (compact) probability density.
