Coming up on StarTalk, we have StarTalk live at the Beacon Theater, New York City.

We're celebrating the 100th anniversary decade of the discovery of quantum physics.

Not only that, the 1920 was when we discovered that the Milky Way galaxy was not alone in the universe.

And that the universe itself was expanding.

So we brought out the big guns for that one.

We've got Jan 11 and Brian Green, two cosmologists with whom you are most familiar,

and a very special comedic guest, Hassan Minaj.

So join me and Chuck Nice as we host that evening coming up.

Welcome to StarTalk, your place in the universe where science and pop culture collide.

StarTalk begins right now.

So before we begin, I just wanted, I didn't know this until today that the two of you

are actually current collaborators on some research.

Could you just highlight what that is?

What are you doing?

I mean, Brian and I have been working together for years.

Mostly, we've been thinking about extra spatial dimensions

and different cosmological implications, implications for theoretical physics,

you know, hiding some dark energy and some extra dimensions.

As one does. As one does.

Yes.

You're thinking about higher dimensions.

Yes.
