A good video on the whole, although I felt there was a little too much talking and discussion when more computer graphics would have been better in such a short video. Despite this, very thought-provoking ideas and theories to make this definitely a good buy.

This show was on fairly recently and I enjoyed it a lot. I'm glad to see that PBS video has it available. It takes a look at the theory of the Big Bang and the recent evidence that light from stars measured are ten times dimmer then they previously estimated and the new data supports the new theory that the universe is expanding much faster then anyone belived and might continue to do so forever. If this is true, then the mathmatics of the sky now seem to suggest that The Laws of Time and Space can only move forward and that Time Travel is no longer a scientific possibility, but an impossibility. Very Good show.

Excellent content. The visuals that take you from our Solar System, out of our Galaxy, out of our local group and then out of our super cluster are stunning. It gives you a real sense of where we live. I purchased this after seeing it on PBS. This is one I can watch many times. Gives strong evidence for the possible acceleration in the expansion of our universe.
