The Known Universe (2009) National Geographic

Alien Contact

From the enormous universe in which we exist to tiny atoms that make up the building blocks of everything around us, size matters when it comes to understanding the cosmos. Starting with our solar system, we'll explore the true meaning of word "big." Odds are you saw a model of the solar system made in grade school. With incredibly realistic CGI, we'll reveal how that model, if built to scale, wouldn't fit inside a football field, much less a classroom. Ever wondered what would happen if you were sucked into a black hole? Or, if wormholes could make time travel a reality? And could life on Earth survive a huge meteor strike like the one that took out the dinosaurs? From the Big Bang to the possibility of alien life and deep space travel, scientists expand our understanding of the universe. This series combines the most current scientific information, cutting-edge computer graphics, dramatic time-lapse sequences and everyday examples to shed light on some of the most mind-boggling aspects of our universe.
