As I just wrote excitons are a combination of the electron. And the hole below it. The image above shows how electrons are hovering above their holes. And because the quantum field of that electron is stronger than other electrons the radiation can travel through it. And that thing can form the quantum hood over the electron. The depth of the electron-hole depends on the force that the photon transfers to the electron. So what is the electron-hole?
Above this text, we see the two-dimensional model of the electron-hole and electron combination. When the energy level of an electron rises to a certain level there forms the energy pillar below the electron. That pillar hovers over the hole and then the electron will drop back to that hole because positive polarity pulls that thing in it.
Image 2) (Pinterest) Tennis ball wind tunnel. The tennis ball can demonstrate how electrons are acting when their speed is high enough. In the case of electrons, the air molecules are replaced by quantum fields.
The electromagnetic wave motion acts similar way but in that case, the electromagnetic wave motion forms the shockwave. In wind tunnels, the air molecules are forming the shockwave. But the wind tunnel image can use as a model for the electromagnetic waves that the particle faces when its speed reaches the speed of light.
When we are thinking about the photons and electrons we must realize that all other energy loads can create the hole below the electron. When an electron travels at a very high speed there it forms a hole or vacuum behind it. In that model, we can think that the kinetic energy pumps energy to the electron and it acts like photons. The hole pulls electrons backward because the system also seeks the minimum energy level.
The minimum energy level is the energy level of the space around the object. That is another thing that makes crossing the speed of light very difficult. Another thing is the doppler wave ahead of the object. That effect known as redshift means that the wavelength of the wave motion ahead of the object turns slower. And an extremely high speed the doppler effect causes that there is the wave motion shock wave ahead of the object.
The shockwave is similar to when the aircraft travels at the speed of sound. The shape of the aircraft aims that shockwave away from the body. And the doppler effect is similar to the molecular effect. But in that case, the shockwave forms because of the electromagnetic wave motion.
That shockwave forms electromagnetic low-pressure around the object. So the energy travels back and sideways from the object because the contact point with the quantum field is so small. So the system must bring energy from somewhere for filling those low-energy areas that are making the energy travel away from the object.
