In the vast expanse of space, nothing matters more than speed. Whether we're venturing out to the farthest reaches of our solar system or exploring the mysteries of time travel and wormholes, speed is the key. With stunning CGI and riveting footage, Known Universe: The Fastest explores interstellar travel, wormholes, and black holes and re-examines Einstein's theories that hint at the existence of portals that could reach through the very fabric of space and time.

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 close captioned. We apologize for any inconvenience this limitation may cause.
