The collapse of the wave function is natural In 1803, Thomas Jung directed a beam of light onto an opaque screen with two slits. Instead of the expected two streaks of light on the projection screen, he saw several streaks, as if two waves of light were interfering from each slit. Over the course of two centuries, many experiments have been performed that have shown that not only light, but any single elementary particle and even some molecules behave like a wave, passing through both slits at the same time. However, if we put sensors at the slits that determine which slit the particle passes through, then the interference pattern disappears. The experiment leaves two questions unclear. 1. As a single particle, it passes through both slits at the same time. 2. Why does the interference picture disappear when installing the sensors? In our opinion, microparticles acquire pseudo-wave properties only in experiments. Outside of experiments, in objective reality, in nature, microparticles do not possess wave properties. In experiments, microparticles acquire pseudo-wave properties due to the fact that microparticles, in addition to mass, have energy. A photon, for example, in addition to mass, emits energy of a particular temperature and of a particular color, an electron, in addition to mass, emits electric and magnetic fields, and so on. Therefore, microparticles easily pass through two slits at the same time, meaning that the photon itself or an electron passes through one slit, and part of its energy passes through the other slit. This is where the effect is born, when the photon interferes with itself. When sensors for the passage of microparticles through the slit are placed on the slit, and the sensors record the passage of a photon, but do not record the passage of a part of its energy through the slit, here the microparticles, from a pseudo wave, turn into normal microparticles that do not have wave properties, therefore the interference picture disappears.   ...
