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.
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.

What everyone has forgotten is that Schrodinger came up with this experiment to highlight the ridiculousness of quantum theory.
Even with a 50/50 chance of the cat surviving there's a 100% chance their restless spirits will come back to haunt you for the rest of eternity for what you put them through
I always root for the best outcome: scientist opens the box, the cat flees and the bomb explodes killing only the scientist
I prefer to just put the cat down there with some quantum string, easiest way to make sure he gets entangled.
Alternatively, by looking inside the box, you also become entangled with it.
Cat is asleep 100% of the time, so actually the cat never sees the gunpowder explode
The cat: Schrödinger, I survived, and I'll avenge my death!
I don’t understand why descriptions of the experiment seems to always leave out the trigger for the poison/exploration being radioactive decay. I thought that was a core part of the thought experiment.
The reason why schrodinger's version is basically a vial of poison that breaks if a detector detects a particle of radiation is to define the cat being alive or dead in terms of a single quantum event.
The scientist doesn't collapse the wave function. They become entangled with the cat.
the cat actually has a 0% chance of dying because i'm rescuing it from this situation every time
There is also C.A.T.S. ending: Cat escapes and thirsts for revenge by building deadly machines of war
So there is a theory, where things don't happen if those chunks are not loaded?
It doesn't collapse. Our reality just also gets entangled with the cat's reality.
This isn’t how this works, it’s not how any of this works. Shrodinger knew this more than anyone
I don't think gunpowder will wait for cat's brain
If it explodes, cat won't live long enough to see it explode.
The point of this thought expirement was to show how absurd Einstien and Schrodener viewed quantum mechanics. However an alternative explanation to this expirement is that if set up properly under perfect conditions, then this expirement is possible, but not only would the cat be entangled, the entire universe is entangled, leading to the many worlds hypothesis.
The cat has a 100% chance of seeing someone open the box. There is never going to be a chance that the cat doesnt see the person who Opens the box.
You got it wrong. The cat can't see the bomb explode, because it's dead before it realizes what happened. The cat can only ever see the bomb not explode. Consequently, the cat is immortal.
