● The wave pattern
The particles are experiencing a „drag” or „friction” while going through the slit. Some particles go through, while others don’t make it to the detector screen. Why is there a pattern on the screen? The pattern is actually formed due to an accumulation of dots, each representing a particle. So, collectively, they appear like a wave imprint. My theory is that the thickness of the slits screen matters because it plays a role in defining the trajectory towards the detector screen. Some are „dragged” to the right or left, and some go up or down, and others simply go through the middle (not interacting that much with the edges of the slit). I am thinking of it like: „a moving particle through a slit, if closer to the edge tends to ‘flow’ alongside the wall (which here is the thickness of the slits screen, which for a particle means a considerable distance)”. This is why the pattern appears: particles squeeze through the slit and interact with the edges (maybe not the particles themselves, but for sure their fields). Electrons, for example, come with an electromagnetic field (electricity in general has a magnetic and a thermal effect). There might be a tendency to curve around the edges of the slit, but due to the high speeds (of the particles), they overcome this tendency and land on the detector screen, forming a wave-like pattern. I am thinking of it like a quantum-level Coanda effect. The Zitterbewegung also plays a role, because it determines how the particle behaves at and after interacting with the slit screen.
● The two-fringe pattern
When we want to observe the particle, we usually send photons to make sense of what is happening, but when the photon collides with the particle, the particle gains energy and a higher speed, so it goes through the slit faster and doesn’t interact that much with the edges of the slit; it manages to overcome the curving tendency.
● Why are there dark regions in a single slit experiment, and why do they become filled with dots in the case of two slits?
Because the field surrounding the particle is interacting in the first case with the edges of one slit, while in the double slit case, it interacts with both slits. So it is like a new setup, and the outcomes are different.
● Time doesn’t matter, because the experiment is based on probabilities, so it is only a mathematical calculus which states that the wave pattern or the two-fringe pattern follows the equation every time.
● Why does the particle go through a slit and not always hit the middle, slits divider?
Because of Zitterbewegung, which says that particles are not static, but are always vibrating. So the vibration of the particle induces an uncertain outcome of the trajectory of the particle: some collide with the middle part while others go through the slits, based on their vibrational state when arriving at the slit screen. Since the Zitterbewegung follows a finite vibrational state (up-down, left-right) I think we can say that the wave pattern on the screen is always there, because a particle also has a finite modes of interacting with the slit/slits, ensuring the nonchaotic waves pattern we observe (due to repetition).

Prediction:
If you were to shine a light beam on a cylinder shaped mirror and place a detector screen at where the light is reflected (where the photons gather), you would notice fringes appearing in a wave like manner. This proofs that particles are particles and they behave as such. A particle can’t be a wave and a particle, a particle is and behaves as a particle, very close to how in a mechanical sense you would shoot small marbles into a cylinder shaped pillar. More particles landing on the detector screen will resemble collectively a wave-like pattern. They physically interact with the cylinder and due to Zitterbewegung (which implies a finite way of vibrations regarding the particle), the wave pattern appears in a given amount of time, composed of many particles landing on the detector.
