Scientists believe that our universe started with a colossal explosion called the Big Bang. That powerful blast created all the matter in the universe and laid the groundwork for every explosion since. From exploding stars to asteroid impacts, Known Universe: The Most Explosive deconstructs some of the biggest explosions in the universe with unforgettable CGI and slow-motion footage. Even a devastating earthquake would be tiny compared to what would happen if an asteroid six miles across slammed into Las Vegas. In spectacularly realistic CGI, experience the impact and its blistering shockwave. Discover how scientists have devised strategies to harness the sun's explosive power to divert dangerous meteorites from slamming into the Earth.

How our DVDs and DVD-Rs Differ
Customers who purchase programs in the NG DVD Exclusives Library will receive a non-interactive, play only disc. There is no chaptering information on these DVDs, but there are chapter marks approximately every five minutes, which make it easy to fast forward through a program. The DVD-R format provides the digital video and audio quality you expect from all of our DVDs.
NOTE: The NG DVD Exclusives titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
