Welcome to Star Talk.

Your place in the universe where science and pop culture collide.

Star Talk begins right now.

Thanks for coming out and giving us your Friday night.

Our next segment is going to be Star Talk All Stars where I take a backseat and we bring on the host.

One of our many talented Star Talk All Stars neuroscientists Heather Berlin.

And my comedic co-host, the one, the only Chuck Knife.

Let me introduce a colleague and a friend, one of the smartest people on earth, theoretical physicist Brian Green.

Let me ask both of you something because you both have to think about this.

Since we're talking about the brain predetermining something you do, you talk about the big bang predetermining all future events.

Then the fact that we experience time is that itself an illusion.

I'm going to say, yes, time is an illusion, the way we experience it.

Now I'm not talking from the physics perspective, right?

But the way humans experience time is an illusion because it's very easily manipulated.

So for example, in experiments we can take something called trans-cranel-magnetic stimulation, which is basically...

Transcranial.

Transcranel-magnetic stimulation, you put a magnet and you can kind of zap different parts of the brain and temporarily knock them out.

People let you do this to them?

We do all sorts of things, Neil.

Why do you think I became a nurse?

I gotta be honest, I'm kind of up for it.

It's a lot of fun.
