Yeah, we're all victims here, I think.

So the way that that works is rather than just observe whether the electron goes to the left slit or the right slit, what do you mean by observe?

You mean like maybe you with your eyeball or with some measuring apparatus have detected it.

But what if you just entangle it a little bit?

Like you entangle it with one little particle, okay?

Then, unlike if you personally had observed it, you could imagine unentangling it.

You could imagine not letting it get the interference pattern destroyed, or you could imagine having it be destroyed.

And you can make that decision after the electron's been detected.

That's the slightly spooky part, right?

That's the spooky part, right.

If you were the kind of person who spoke a language of the electron goes through one slit or the other slit and it's making a decision, then what Chuck says, like, it sounds like the electron's decision was affected by what I did after it was detected.

Oh, my God, how could that be?

Right.

But if you just talk the language of a wave going through and becoming entangled and taking quantum mechanics seriously, all of this is 100% what is predicted by the Schrodinger equation of quantum mechanics without anything, knowing anything, anything, making any choices or anything going backward in time.

It's hard to explain, but I encourage people to Google Notorious Delayed Choice Quantum Eraser and they will find my blog post and they will hear it all.

This is literally the chapter I wrote for my book, Something Deeply Hidden, which is all about quantum mechanics.

I read the chapter and said, this is too much.

They don't need this.

This is too complicated and specific, so I just made it a blog post instead.
