And so he said, well, when would the decision have to be made about whether the light goes to the left or to the right?

And suppose it's halfway between us and the quasar.

So suppose that's a half a billion light years away.

So the decision would have had to have been made half a billion years ago, so 500 million years ago.

We're talking about the past, but the deep past.

We're talking about dinosaur age, right?

Maybe even before the dinosaurs.

But what this experiment shows us is it's not until the light is measured here on Earth

and we measure what's called its polarization, which is the same as saying whether it went left or right, that the decision about whether it goes left or right is made.

Now, it's made now when we measure it.

Now, that's just really bizarre because that's saying there's more than one possible path.

And so I wasn't sure I was interpreting this right.

And I went back and I found an obscure quote from Schrodinger, who, again, one of the forefathers of quantum mechanics, the Schrodinger wave equation.

And he said, in an obscure speech, he said, effectively, when we're collapsing the probability wave, which is one of the interpretations of what happens for the observer effect, is that

You have all these probabilities and then you come down to just one.

That's the one you observe.

The cat is alive.

That's it.

But Schrodinger said we're also choosing from one of multiple simultaneous histories, which just gets really bizarre.

Now, why do I go into this kind of detail when I'm talking about simulation theory?
