Dear readers, if you have found this article, you must be a person who likes to talk about the quantum universe
So, the famous double slit experiment first gives us a hint about the mysterious behavior of these quantum particles. If we take a board and cut a hole in it and throw beads through it, we will be able to see a very clear vertical mark on a screen on the other side. If you cut two holes in this board, you will be able to see two clear vertical lines on the screen.
If we send a water wave through this hole, after the water wave passes through this hole, the wave will scatter in both directions. Then we can see a vertical mark on the screen. If we cut two holes and send a water wave, then we will be able to see something special there. Then we can see on the screen a lot of vertical marks. We call this an Interference Pattern. Not only water waves, but any wave behaves in this way. If we now cut a hole in a board and send electrons through it, we will see a clear vertical mark on a screen on the other side and get the count. Because we all know that an electron is a particle. If you cut two holes and send electrons through them, you would think that you would get two vertical marks, right? Dear readers, but when we actually did this test, we could see an Interference Pattern. So, this became a big controversial event in the physics world.
So, scientists thought that when a stream of electrons travels through space, they collide with each other and behave like a wave. After that, the scientists tried sending these electrons one by one, but they got the same interference pattern as before. Next, the scientists wanted to know which electron went through which hole and then these guys have a particle detector in front of one hole so that we can know which electron went through which hole. The results of this test are even more surprising. In this result, we could see two clear vertical marks, which means that the electron behaves completely as a particle.
Dear readers, we observed that as long as we do not observe the electron, it behaves like a wave and when we observe the electron, it behaves like a particle. So, readers, from this, there is an opinion in the world of science that the reality we live in is not true. If you have seen the matrix movie, there is an opinion that something similar exists in the universe. This is called simulation theory. But still no one has been able to solve this double slit experiment. If you can solve this, you will get the Nobel Prize for Physics.
