First, your statement that no one should comment until they've read the source is one of the dumbest things anyone's ever written. If you've summarized the article and done a good job, we should know enough to comment. If you've not simply summarized the article, I'm commenting on the opinion that you've added to it. Your disclaimer makes me suspect the latter.
Second, articles like this do nothing more than make people want to do things like building space ships. A hundred years before we walked on the moon, it was said to be impossible; some still disbelieve. A hundred years before we flew, it was said to be impossible; many are still fearful. A hundred years before electricity was "invented," it was said impossible that such a thing could be conceived of; almost everyone has converted. A hundred years before the discovery of the wheel, people thought dragging things from one place to another was pretty neat; everyone now uses wheels.
By the simple study of history, one sees that naysayers are continually proven wrong by inventors and scientists. You are clearly too short-sighted and closed-minded to be the sort of visionary that makes it happen instead of sitting around and writing piffle about how this could never happen.
When the invention or discovery comes, it'll be something that you (of all people) didn't even think we could do. It'll also be something that you probably didn't imagine could apply to space travel. Not only will we figure out how to do this, but in a couple of millenia, it'll seem commonplace.
Leave the thinking to the folks at NASA. Not only are they better at it, but they're also doing something constructive along the way.
