Schrödinger's Cat

People who studied or took an interest in Physics might have heard of 'Schrödinger's Cat'. But in case you haven't, here's the brief account: The Austrian physicist Erwin Schrödinger left his cat inside a gas chamber by accident. During this period, there is a 50% chance that the poison gas might be discharged. So is the cat dead or alive in the end?

Schrödinger's Cat was simply a teaching tool that he used to illustrate how some people were misinterpreting quantum theory. The imaginary experiment was constructed to show that over simplistic misinterpretations of quantum theory can lead to absurd results which do not match the real world. Einstein saw the same problem with the observer-driven idea and congratulated Schrödinger for his clever illustration.

Of course, the basic concept of quantum theory states that any particle is in a superimposed state (decay or non-decay) until verified under observation. Suppose the release of the poison gas is dependent on whether the particle decay or not decay, then the fate of Schrödinger's cat is subject to a 50-50 chance of survival. That being the case, before any observation is made the particle must of necessity be in a superimposed state, meaning the cat too must exist in the duality state of being alive and dead at the same time. Confused already?

Schrödinger's cat could be dead a second ago, then become alive the next second, dead again two seconds later, and alive once more three seconds thereafter, in random overlap until you open the door to check its being, then would this overlapping state come to a complete stop. And until you do so, the cat will go through an endless iteration, like a dice that keeps on rolling without knowing the final number it will end up with. As Einstein remarked:

God does not play dice (with the universe, that is).
