Cats can't talk, so they can't express themselves even if they experience life and death. But people are different. If people feel superposition, they can express it. So, if you put a person in a box and open it, if he is still alive, will this person tell you his state of life and death?
Unfortunately, firstly, people didn't carry out such cruel experiments, and secondly, even if such experiments were really carried out, there would be no superposition. When a person is put into a box, his consciousness has participated in the experiment, and his consciousness will also cause the state of particles to collapse, so when he realizes this problem, he decides his own life and death.
If he doesn't realize it, he will still be doomed, because the consciousness of the person who locked him up will be entangled with him, leading to the collapse of the particle state, but cats don't have this problem. Because cats seem unconscious.
Extended data:
First, Schrodinger's cat theory:
Put a cat in a closed container with a small amount of radium and cyanide. Radium has the possibility of decay. If radium decays, it will trigger the mechanism to break the bottle containing cyanide and the cat will die. If radium doesn't decay, the cat will live.
According to the theory of quantum mechanics, cats should be in the superposition state of dead cats and live cats because radioactive radium is in the superposition state of decay and non-decay. This dead and alive cat is the so-called "Schrodinger cat".
However, there can't be a dead cat and a live cat, so you must open the container to know the result. This experiment tries to explain the principle of quantum superposition on the micro scale from the macro scale, and skillfully links the existing form of microscopic matter after observation with the macro cat, thus verifying the existing form of quantum when it comes to observation. With the development of quantum physics, Schrodinger's cat has also extended physical problems and philosophical disputes such as parallel universe.
Two. Conclusion as of February 22, 20265438 +0:
According to quantum mechanics, microscopic particles are always in the superposition state of multiple states. In the earliest double-slit interference experiment of photons and electrons, it was found that a single photon or electron would inexplicably pass through two slits at the same time, that is, a single photon or electron would pass through the left slit and the right slit at the same time. When people try to observe what kind of superposition state this is, photons or electrons will instantly degenerate into a single particle state.
In short, it is impossible to observe. More research finally leads to the mainstream explanation of quantum mechanics by Copenhagen School, that is, microscopic particles (including macroscopic objects) are always in the superposition state of multiple states, and once human consciousness participates in observation, the particles collapse into a certain state with a certain probability. Thus, the lofty position of "consciousness" in the mainstream school of quantum mechanics is established, and the unobservability of superposition state is declared at the same time.
