Known Universe

Season 3

Travel through the universe to explore the really big questions. Is there life on other planets? Just how big was the Big Bang? What would traveling at "warp speed" really look like? Could wormholes make time travel a reality? Could life on earth survive another huge meteor strike like the one that took out the dinosaurs?
