Oh the Places We Won’t Go: Humans Will Settle Mars, and Nowhere Else

Sorry, science fiction fans, traveling to distant stars is indeed fiction, at least for human beings. We will settle Mars but everything beyond that will be explored by robots.

This doesn’t mean there might not be some way to “cheat” the laws of physics as we currently understand them because there might be. But we haven’t found it yet. The lack of interstellar visitors to our own world tend to support the idea that there is no cheat. Of course, to the best of our knowledge we haven’t seen any robots either, so consider this question open for now.
