okay so if i understand this right, if i take half of schroedingers box and open it up, by observing the half of the cat i have i will instantly know if the half of the box the other guy's got has got half of an alive cat in it? and i'll be able to tell if his half of an alive cat is purring and void or garfield and shit is my stupid analogy right?

but i cannot pet my half of a cat and make it purr and thus make their half of a cat purr. because cats do not work that way.

    You want to cut Schrödinger's box in half? This kills the cat, unless the box is big enough for the cat to avoid the blade, in which case you've opened the box and the cat is probably going to need some convincing to get out from under whatever furniture it can find.

    schroedinger's cat is an intentionally absurd metaphor from when QM dorks were still arguing about spooky action at a distance.

    Both the cat, the box, the vial of poison, and the cesium atom itself are all observers as far as a real QM wavefunction would care. But as i understand it, getting any utility out of the idea of real collapsing wave-functions requires treating at least the atom as if it wasn't, and once we start including atomic scale things we might as well just include everything up to and including the cat.
