Why Not to Fear Black Holes with Astronomer Ian Morison
Black Holes seem to have bad press that is largely undeserved. This lecture with professor Ian Morison explains what Black Holes are, and how we can discover them even through they can’t be seen.
This program was recorded in collaboration with Gresham College, on October 27, 2010.
Gresham Professor of Astronomy Ian Morison made his first telescope at the age of 12 with lenses given to him by his optician. Having studied Physics, Maths and Astronomy at Oxford, he became a radio astronomer at the Jodrell Bank Observatory and teaches Astronomy and Cosmology at the University of Manchester.
Over 25 years he has also taught Observational Astronomy to many hundreds of adult students in the North West of England. An active amateur optical astronomer, he is a council member and past president of the Society for Popular Astronomy in the United Kingdom.
At Jodrell Bank he was a designer of the 217 KM MERLIN array and has coordinated the Project Phoenix SETI Observations using the Lovell Radio Telescope. He contributes astronomy articles and reviews for New Scientist and Astronomy Now, and produces a monthly sky guide on the Observatory’s website.

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.

Please Explain: Matter, Anti-Matter, and Dark Matter
Please Explain is all about matter, anti-matter, and dark matter. Lisa Randall, Professor of Theoretical Physics at Harvard University; Michael Tuts, Professor of Physics at Columbia University and Mordecai Mark Mac-Low, Chair of the Department of Physics at the American Museum of Natural History tell us all about what it is and what it means.

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.

Sir Roger Penrose | The Road to Reality: A Complete Guide to the Laws of the Universe
Sir Roger Penrose is Emeritus Rouse Ball Professor of Mathematics at the University of Oxford and is the best-selling author of The Emperor’s New Mind. He is the recipient of numerous prizes and awards, most notably the Wolf Prize in physics, which he shared with Stephen Hawking for their "development of the theory of general relativity, in which they have shown the necessity for cosmological singularities and have elucidated the physics of black holes… enlarging our understanding of the origin and possible fate of the Universe." Penrose was knighted in 1994 and currently lives in Oxford, England.
