Coming back to Schrodinger's cat, we say there's two possibilities, right?

So with 64 qubits, there's two to the 64 possibilities, if they're all in superposition.

They have all the possible values of it.

And so basically, when you measure that,

it brings it back.

And so physicists call this the collapse of the probability wave.

So there's a probability of all these possibilities, and then it comes down to one.

And that's sort of the best, one of the accepted ways that people think this whole thing works.

But nobody totally knows.

So another guy who was John Wheeler's grad student at Princeton came up with another idea.

And we've heard about this idea from the superhero movies, right?

And this is the multiverse idea, right?

Yeah.

And so basically he said that if you've got Schrodinger's cat, what happens is you're splitting the universe into two different universes.

In one of them, the cat is alive.

And another one, the cat is dead, right?

So that's the multiverse idea is that when we measure it, we only see one of those two because we're in this universe.

But if we happen to be in this other universe, the cat would have been dead, right?

The cat is alive here.

And so that creates a whole series of possibilities which are being used now in superhero stories all the time.
