Alan Alda in Scientific American Frontiers

The Dark Side of the Universe (#1405)

Alan Alda joins some of the world's leading astronomers as they wrestle with the startling implications of their latest discoveries: that everything we can see, from the world around us to the most distant galaxies, is only a tiny fraction of the entire cosmos. Most of what's out there is dark - either dark matter or dark energy. And our universe is perhaps only one in an infinity of universes. [56 minutes] Closed Captioning
