"Schrodinger's cat" is one of famous thought experiments. Many people have ever heard of that name once.


First of all, put explosive bombs and cats with explosive probability of 50% within one minute in the powder magazine.


It is the Einstein version that uses bombs in this thought experiment, and the inventor Schrodinger liked using toxic gases instead of bombs.


Because we can not see inside the powder case ......


I do not know until the catch actually died or not whether the cat died or live after 1 minute.


However, if you repeat this experiment, the probability that a cat will die will be 50% the same as the probability that a bomb will explode.


Even though it has already been decided whether the cat has died or is alive, it is not known until which it is actually observed until the observation that this is because the cat's life and death are "overlapping states" I can say that. And this overlapping state is quite perfect to express the state of particles in quantum mechanics. It is believed that in quantum mechanics particles are considered to exist in various states "in an overlapped state" and "overlapped state" converges to one state by observing particles by observation equipment It is because it is thought.


Whether a cat is alive or dead is determined at the time of observation, so the curiosity of "I want to know what is going on" kills the cat.


Then what will happen if you think from the cat side's viewpoint? Cats actually see with eyes whether the bomb will explode or not in the powder magazine, but from our side "the bomb explodes and the cat sees an explosion" or "the bomb does not explode , Cats do not see explosion ".


There is no possibility that "the bomb exploded, but the cat did not see the explosion".


Therefore, it seems that the content of cat's side reality and thought experiment 's content is "If the explosion happens, the cat dies, cats will not die unless it catches up."


This thinking experiment is like one observing naturally "breakdown" of one option.


Also, as the observer sees someone who is observing "a person observing a living or dead cat" like a cat in a gunpowder, the two options are "overlapping It can be caught as if it is in the state ".


Also it is said that both possibilities are occurring in parallel in the pluralistic universeEverett's multi-world interpretationAlso exists.


It is still unsolved problem in quantum mechanics that "this failure" naturally "fails" this one option.
