Schrodinger's cat.

I'm sure you've heard some version of this famous thought experiment: you put a cat in

a bunker with some unstable gunpowder that has a 50% chance of blowing up in the next

minute, and 50% chance of doing nothing. [the gunpowder is Einstein's version - Schrodinger

preferred poisonous gas] So until we look in the bunker, we don't know whether the cat

is dead or alive, and when we do look, it is either dead or alive. But if we repeat

the experiment enough times with enough cats and bunkers and gunpowder, we'll see that

half the time kitty survives, and half the time kitty goes bye-bye. The quantum mechanical

interpretation is that before we look, the cat is in a superposition - it's both dead

AND alive - and our act of looking forces nature's decision. So our curiosity kills

the cat.

But what about the cat's perspective? Well, the cat either sees the gunpowder explode,

or not – so inside the bunker we actually have these two possibilities: "the powder

exploded and the cat saw it explode" or "the powder didn't explode and the cat didn't see

it explode". There's no option: "the powder exploded and the cat didn't see it explode"

- so the cat's reality becomes entangled with the outcome of the experiment! And it's our

observation of the experiment that forces nature to "collapse" to one option or the

other.

But we're like the cat, too – either the cat dies and we see it dead, or the cat lives

and we see it alive – so who's observing us to force nature to "collapse" to one reality?

Or do both possibilities happen in parallel within a larger multiverse?

This "collapsing to one reality" problem is one of the biggest unanswered questions in

quantum physics. So for kitty's sake, can i has answer pleez?
