You're listening to Radiolab from WNYC.
Rewind. Rewind.
Hey, this is Radiolab. I'm Lathif Nasir, and today I have got for you two Radiolab segments that came out before I ever worked here. Both of them do a thing that I find myself craving more and more these days, which is they pop you out. They pop you out of the news cycle. They pop you out of whatever interpersonal drama you're stuck thinking about. They pop you out of your own body.
These are pieces about dimensions and even universes that are imperceptible, verging on almost unthinkable. I mean, I think I get it. I think I understand. Maybe I don't. But I still found it all really fun. So I hope you enjoy this pre-scheduled break from your perceptual reality. It begins with our emeritus host, Robert Kralwich.
talking to our other emeritus host, Jad Abumrad, about a conversation he had with a legendary physicist.
Okay, so this is about what you do for a living. You know that I have this neighbor and friend, Brian Greene.
Brian Greene, professor of physics and mathematics, Columbia University.
Yes, I do know that. And the thing about Brian is he is a theoretical physicist. Now, theoretical physicists say that it's theoretically possible to know everything there is to know in the universe. So one day they'll be able to explain not only how you could send a rocket to the moon, but the laws that govern space and energy and time.
and gravity, everything, the whole universe, one day they think might be totally understandable using logic and mathematical equations.
