And it takes us right back to both the quantum physics idea that the past is not what we think it is.

And there was a guy, Schrodinger again, who actually made an obscure speech in the 1940s, I think, where he said, not only are we choosing which slit, the double slit experiment goes through now, let's say Schrodinger's cat is alive or dead.

But we're choosing from one of several simultaneous histories when we make that observation.

So that means there's a whole history where the cat came in from the front yard versus the backyard.

And before that, the cat belonged to somebody else.

There's a whole history that goes with the choices that are made.

And so this is not a very well-understood example.

aspect of the weirdness of quantum mechanics.

But I think it gets to this idea that maybe there's multiple possible pasts and that we choose those as we run.

Now, if we think of this as a simulated reality, then it becomes a little more understandable.

So I said the main argument people have on the multiverse idea is that – or physicists have, right?

So some physicists like the Copenhagen interpretation it's called.

Niels Bohr came up with it in Copenhagen.

He and his other folks.

That there's a probability wave and it collapses into one.

We don't know how it works, it just kind of collapses.

Some physicists like this multiverse idea because they're like, we know how the mathematics work, but the problem is it ends up in all these physical universes.

I've never seen a planet clone itself, let alone an entire universe, a physical universe.

Cloning may happen, but it happens at a very small level and then it grows.

Even if you clone a sheep or something, you still have to grow the sheep or you clone a tree.
