Seven Possible Scenarios For Manned Interstellar Travel

starshipSince we learned that Voyager 1 has been in interstellar space for over a year, it’s become a bit easier to imagine that someday humans might follow. At the moment, we’re a bit more focused on getting humans to Mars and watching how that goes on reality TV, but scientists are thinking big and many of them believe that we can make major strides in interstellar travel in the next 100 years. That is, if the government gets its act together.

Of course, while some scientists believe colonizing space is an eventuality, others believe it’ll never happen, and some, including NASA’s former Breakthrough Propulsion Physics Project head, Marc Millis, question the claim that we could reach the stars this century. The problem is that we don’t currently know of a way to power these trips, and even when we do figure that out, it’ll take a while to implement those technologies in interstellar spacecraft. Still, even Millis is game to try — he founded the Tau Zero Foundation to research technologies that might propel us beyond the solar system.
