Could someone explain the "Schrodinger's Cat" experiment to me? Hello, I wanted to have an idea of what this experiment is. I just passed my 10th grade and so I don't quite grasp the meaning as it's been explained in Wikipedia. To quote from it: "A cat, along with a flask containing a poison, is placed in a sealed box shielded against environmentally induced quantum decoherence. If an internal Geiger counter detects radiation, the flask is shattered, releasing the poison that kills the cat. The Copenhagen interpretation of quantum mechanics implies that after a while, the cat is simultaneously alive and dead. Yet, when we look in the box, we see the cat either alive or dead, not a mixture of alive and dead." @ Bold: This is where I lose them. My question regarding this are: =What is this experiment used to prove/observe? =How can something be both alive and dead at the same time? =Is this, by any means, connected to the "Many-Worlds Interpretation"? Can someone please cut it down for me to the point that someone with grossly limited knowledge on Physics can understand? Thanks in advance.
