Captain Kirk Returns to Space

William Shatner’s brief flight to the edge of space last year was one of those life-imitating-art-imitating-life moments. Shatner’s famous for playing Captain Kirk on "Star Trek," which has ignited the imagination of generations of scientists. And here we are in the age of commercial space flight –where anyone with the right money or connections can actually go to space, including Captain Kirk himself. So let’s take a look at how "Star Trek" and science have influenced each other. Lawrence Krauss is the world’s leading expert on this. He’s a theoretical physicist at Arizona State University –that is to say, he’s a serious scientist. But he’s also the author of “The Physics of Star Trek” and its follow-up “Beyond Star Trek.” (AP Photo/LM Otero, File) (Produced by Sydney Jezik)
