What does this science joke mean?

In quantum science, there is an experiment called "Schrodinger's cat". The content of the experiment is probably: the cat is sealed in a secret room with food and poison in it. There is a hammer on the poison bottle. The hammer is controlled by an electronic switch which is controlled by radioactive atoms. If the nucleus decays, it will release alpha particles, trigger the electronic switch, the hammer will fall, the poison bottle will be smashed, the cyanide gas inside will be released, and the cat will die. This cruel device was designed by Schrodinger, so this cat is called Schrodinger's cat.

If we don't open the lid of the secret room, according to our daily experience, we can conclude that the cat is either dead or alive. These are her two eigenstates. However, if Schrodinger equation is used to describe Schrodinger cat, it can only be said that she is in a superposition state of life and death. Only by lifting the lid can we know for sure whether the cat is dead or alive. At this point, the cat's wave function immediately shrinks from the superposition state to an eigenstate.

Quantum theory holds that the cat will never know whether it is dead or alive without opening the lid, and she will always be in a state of superposition of half-dead and half-dead.

So he stayed at Schrodinger's house, which means he has psychic experience.
