Schrödinger’s cat

637 viewsOtherPhysics

I don’t understand..
When we observe it, we can define it’s state right? But it was never in both states. It was only in one, we just didn’t know which one it is. It’s not like if I go back in time and open the box at a different time, that the outcome will be different. It is one of the 2 outcomes, we just don’t know which one until we look. And when we look we discover which one it was, it was never the 2 at the same time. This is what’s been bugging me. Can anyone help explain it? Or am I thinking about it wrong?

Schrödinger gave the cat example as a way of criticizing a certain interpretation of quantum mechanics. According to that interpretation, before you make the measurement, the cat is neither alive nor dead, but somehow in superposition of both. Schrödinger was saying that’s absurd, so that interpretation of QM should be rejected.

Then popular culture misunderstood the point as being that physics says cats are sometimes both alive and dead before they’re observed.
