Does quantum mechanics violate the law of causality because it is not applicable?

It means that any phenomenon or thing has a direct or indirect relationship. In Newton's classical mechanics, we can understand it like this. As long as all or all the initial conditions are met, the development law of things can be expressed by a set of formulas. Even if it is complicated, it is just that the input parameters are different. How many parameters are selected, how many outputs are possible!

Second, does quantum mechanics violate the law of causality?

The most typical movement is the movement of electrons. In the past, people thought that electrons moved around the center of the nucleus like planets, but unfortunately this was not the case. Electrons have a prescribed orbit, but that's only the area where they randomly haunt. If the energy given to them is high enough, no process will jump to a higher orbit and suddenly appear there. Do you need such skills?

The above two cannot be determined at the same time, which is crazy in classical mechanics!

Another case is the double-slit interference experiment, especially? Enhanced version? The double-slit interference experiment may make the experimenter feel creepy, because the way to measure the second half of the photon actually interferes with the behavior of the photon that has not yet reached the test point. This is an experiment in which the future determines the past!

The above picture is an enhanced version of the double-slit interference experiment, and interested friends can learn about it!

But do they violate the law of causality? This is actually the world of quantum mechanics. Should the law of causality stand aside? The quantum world obeys the rules of quantum mechanics, and the outcome of the microscopic world is determined by probability theory, just like the orbit of electrons. I don't need to know where it is, but we know it will jump into this orbit!

But one thing we can't deny is that the quantum movement in the micro world will eventually appear in the macro world! For example, the transition of electrons will emit photons, and the photon frequency will be different with different transition energy levels. Numerous electron transitions will emit electromagnetic waves, which will be very hot and hot to the touch, and even glow until X-rays or even? Ray, is this the law of cause and effect? Will the causal law of quantum mechanics be manifested in the macro world? Can't you understand it this way?

Copenhagen annotation shows that in the world of quantum mechanics, wave function is used to describe quantum dynamics. Probability theory is an indispensable tool in quantum mechanics. We should get used to this expression and don't try to match all the teacups with one lid. This is not only futile, but also a joke!
