This question already has an answer here:
I would be grateful for any comments regarding two variations of Schrödinger's Cat experiment I’ve been pondering.
In the first, wishing no harm to the animal, I remove the cat and replace it with a very simple clock. The clock could be mechanical, chemical or atomic in nature, and is just the simplest way to measure time after an event occurs. It is totally enclosed within the box and will start when the radioactive decay event is detected.
Sometime after the experiment begin I look into the box. Sometimes I would expect to see the clock had not been activated but other times it has. In those cases, what will the clock show? Common sense (AKA classical phyiscs) would say it would show an apparent random value but, if I repeated the experiment enough time, I would see it was related to the probability the radioactive substance has decayed. What I would not expect is the clock to consistently showing that it started only when I looked inside the box. If the quantum state only collapses when I look, how come the clock might say it started minutes ago?
EDIT: I am particularly interested in the apparent paradox of an event triggering an event in the past. How, in quantum terms, would this be explained?
Variation 2 is also simple but a bit more dramatic. Here the cat is replaced with a (very small) explosive device – just enough to blow the box part. If I never look inside the box and hence the quantum state is never observed, does the box never explode? If it does explode before I look inside, why? And if, after a long time, the box has not explored and I then look inside, does this mean it’s very like the box will exploded at that moment and I get my hair singed!
Your thoughts please. Bryan.
