Welcome to a special episode of How On Earth with Dr. Seth Shostak, the Senior Astronomer at the Search for Extraterrestrial Intelligence Institute. We’ve been listening for their tell-tale signal for 50 years with no luck, but Seth says that he’ll bet a cup of coffee we’ll hear from them in the next few decades. We explore what might happen if we find these brainy aliens or if we don’t find them at all. It’s part of the Conference on World Affairs.

The Universe Within (starts at 4:40) Within each and every one of us is the history of life on this planet, the planet itself and the entire universe. This is the theme of a new book “The Universe Within.” The author, Neil Shubin, is a professor of Paleontology and Evolutionary Biology at the University of Chicago. Starting with what physically constitutes a human being and what makes a human life possible, Shubin surveys many domains of science to find out what we can learn about what’s out there from what’s inside of us. It’s a fantastically broad scope, bringing together the common history of Rocks, Planets and People. As professor Shubin explains to How On Earth’s Chip Grandits, it is the very concept of this common history that binds all of these topics, which are normally found scattered throughout disparate domains of science and academia.
The concept of a parallel universe, a universe remarkably like our own but with some subtle difference, has been the staple of science fiction stories for years. But it is an idea that is seriously discussed in real science starting many decades ago when physicists wrestled with the weird implications of Quantum Mechanics, and recently has appeared in many other guises in other areas of physics. One of the leading scientists in studying these ideas and explaining the mind-bending concepts to non-experts is Professor 
Russian Meteor (starts at 4:28) Just a few days ago on February 15th, a large meteor broke up in the skies over Russia, creating an air blast and sonic boom, which caused damage to buildings that injured over 1,000 people. We talk with 
Dark Matter (starts at 12:45) Maybe you’ve heard about it. Maybe you even know that it is everywhere throughout the universe. But for such a ubiquitous material, what do you really know about Dark Matter? If the answer is “Not much,” don’t worry, you are in good company; many scientists would say the same thing. But, you’re in luck because we have
