DARPA's Long-Term Long Shot To The Stars
In short weeks, the United States Defence Advanced Research Projects Agency or DARPA, will award a $500,000 to a group with the best plan for developing a way to send a living human to another star system sometime in the next 100 years. Paul Davies says that transporting a human being billions of miles in space "is not physically difficult". However Davies added "its immensely expensive to do so in a manner that wouldn't kill the astronauts". Overall there's will be 2 issues that might stymie long-distance space travel. One is money, and the other is threat to the travelers. But Davies stated he rather send nano-probes rather than humans.
