So he said, who changed it, right?

Did somebody change from the chain to the light switch?

But nobody had changed it.

And so he couldn't figure out what was going on.

And so he kind of theorized this whole idea that as we run different versions of the simulation, little things can end up changing and we remember things being different.

So anyway, where that brings us is right back to that complicated physics experiment that I was telling you about.

an hour ago now or so, which was the delayed choice experiment.

Remember I said there was a quasar sending light to us a billion light years and a million light years away there was a black hole and the decision about whether to go left or right should have been made in the past, should have been made a million years ago.

But the weirdness with quantum mechanics is telling us that decision is made now when we measure it.

Until then, both possibilities actually exist.

So most people can understand the multiverse idea as being something that starts here and spreads out, right?

You're like, I go to college in Boston.

I go to college in San Francisco.

Those are like two different storylines.

I marry this person.

I marry this other person, right?

So those are multiple possible futures.

That's pretty easy to grasp the idea of, you know, even if you don't believe the futures are out there, you just say if you make choices, you end up in different places.

But the weird thing that is really hard to put your mind around is what if there are multiple possible paths?

What if there was a past where the light went left?
