By the year 2022, only Schrödinger's immortal cat remained, still active in the crevices of quantum mechanics.
As for Schrödinger's cat...
Many people think this experiment only involves a single cat, without any supporting elements.
That is, simply put the cat in a box and ignore it—if the box isn't opened, we won't know whether it's dead or alive.
In reality—
The experiment is far from that simple, otherwise Schrödinger wouldn't have earned the reputation of being a cruel cat abuser.
According to Schrödinger's hypothesis—
He first puts the cat into a closed, opaque box, then adds a radioactive atom inside (with a 50% decay probability).
Plus a particle detection device, a bottle of deadly poison, and a hammer.
If the radioactive material decays, the detector will pick up the emitted particles.
Then a signal is sent to trigger the hammer, which smashes the bottle containing the poison, sealing the cat's fate.
If the particle doesn't decay, the cat will survive.
