Now that Google has effectively conquered Earth, the all-powerful Web giant is setting its sites on a new frontier: Mars. Calling it "The Adventure of Many Lifetimes," Google co-founders Larry Page and Sergey Brin just announced a joint venture with Virgin CEO Sir Richard Branson to colonize the Red Planet because, as the press release states, "Earth has issues, and it's time humanity got started on a Plan B." Uhhhh, right. Happy April Fool's Day, folks. There's nothing funnier than billion-dollar corporations taking time out of their busy multinational money-making days for a little light humor. http://www.time.com/time/arts/article/0,8599,1726938,00.html?cnn=yes http://www.google.com/virgle/index.html
