If you open a door to a dark room while there is light behind you, the light will enter the geometric shadow, meaning the result of the oppening will not fully comply with the laws of geometric optics. If you perform a double-slit experiment by shining monochromatic light on two openings in a screen, bands will form on the resulting screen, which shouldn't happen due to the principles of common physics.
What these two experiments have in common is that Compton scattering occurs when atoms, their electrons and nucleons reflect photons. The reason for light entering the shadow and the appearance of fringes is the same, which directly follows from Einstein's postulate about the maximum possible speed of light.
When turned inside out, this postulate states that there exists an absolute standard of time, meaning nothing can happen faster than the minimum possible time interval. The penetration of light in the shadow and the fringes on the screen confirm the existence of this standard, and that the speed of light is indeed the maximum possible.
Indeed, electrons and other atomic elements have spins, meaning they rotate by some angle over some time, which is greater than or equal to the standard, but never less. As a result, there is the penetration and the fringes in the aforementioned experiments.
Therefore, scientists need to stop working in the field of quantum mechanics, as the aforementioned experiments convincingly prove that the photon is a particle without any wave properties. However quantum physics predominantly works with the photon as a wave, which is an error.
