“So, according to the theory that electrons are in all-possible-positions until they are measured, the cat is both alive and dead until we open the box and find out if it is alive or dead.
It seems to me that all the things we keep in sealed boxes are both alive and dead until we open the box, that the unobserved is both there and not.
Eventually, they figured out that keeping the box closed doesn't actually keep the cat alive-and-dead. Even if you don't observe the cat in whatever state it's in, the air in the box does. So keeping the box clothes just keeps you in the dark, not the universe.”
