"We once considered ourselves to be at the center of the universe--now we know that we are just a small spec in a giant cosmos. This season, History ventures outside of our solar system in another epic exploration of the muniverse and its mysteries. Wtih strikingly realistic computer re-creations, you'll feel like you've traveled to the edge of the unknown: visit strange and unfamiliar worlds, prepare for the worst, nd uncover the secrets of ur own galaxy. And that's just the beginning, learn what "dark matter" is and how it takes up 95% of the universe ; take a front row seat for the ultimate light show and while most people have heard of black holes, find out more about "White holes" which actually create matter."--Container.
