Doubtful that it'll ever happen, though I'm always hoping it will. We do not currently own the appropriate resources to cause those events, and we're certainly not "fit to rule"/aid judging by our actions now. The technological challenges to reach those goals have been, unfortunately, belittled by the huge science-fiction hits we all love. Simply put, most people don't recognize how large the numbers at play really are, when talking about space travel. People look at 1 million, and then 1 billion, and don't put so much as an afterthought into just how big the disparity is. I read a comparison earlier today that made it a bit easier to understand. 1 million seconds comes up to ~11 days. 1 billion seconds comes up to ~31 years. We're talking lengths of interstellar travel that [i]start[/i] at 100,000,000,000,000 kilometers, and people think that we may at some point compete with light speed. Sorry to say, but even the closest stars would take you years to reach at that speed, and with those distances. Dare I even mention the fact that the passengers would not be viewing time in the same way as the people on Earth? By the time they got back from their trip, the entire planet could be a [i]very[/i] different place. Wait though, now we've got people talking about FTL travel. The most prominent of which is an engine that contracts space in one direction, and expands it in the other. This is, in my opinion, the only hope we've got. Currently, I don't think it's possible in the limits of our current understandings of space, and the matter we have at our disposal. Hell, even the people working on those designs simply state that they need "exotic" matter, and that they'd need quite the abundance of it. So we're in all likelihood stuck in our current position. At least, until we discover something new about space-time. Something big enough that it's end result will have launched our civilization into a functionally inextinguishable status.
