Radiolab: Falling
http://www.radiolab.org/2010/sep/20/
This hour, Radiolab rollicks through stories of falling. We plunge into a black hole, take a trip over Niagara Falls, and upend some myths about falling cats.

Astronomycast 145: Interstellar Travel
In science fiction it’s easy to hop into your spaceship and blast off for other stars. But the true distances between stars, and the limits of relativity make interstellar travel almost impossible with our current technology. What would it really take to travel from star to star, exploring the galaxy?

Radiolab - DIY Universe
Can you make your own universe? We usually think of the universe as “everything that exists,” so how could you make another one? Well, physicists have been speculating about the existence of multiple universes for some time now. And for Robert, the obvious next question was: “Can we make one?” So he invited physicist Brian Greene to his kitchen to speculate about just that. And it turns out, it’s not such a far-fetched idea. There are scientists right now trying to figure out whether it’s possible and what it would take. According to Brian, it would require a tiny black hole, a dash of reverse-gravity, and a lot of luck. But the laws of physics don’t rule it out.
