The Dark Side of the Universe
Description
In this episode of Scientific American Frontiers, 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.
