* Warp drive enabling faster-than-light travel is a sci-fi staple and an offense against the laws of nature as we now know them, but physicist Richard Obousy says there's some theoretical science behind the concept — it's just a matter of harnessing "dark energy" and taking advantage of additional dimensions predicted by string theory in a way that would allow a vessel to envelope itself in a bubble of spacetime, which, if the Big Bang is any indication, should be capable of moving far faster than light. Or something like that. He's even mocked up a concept of how such a vessel might look — less like the Enterprise and more like a couple of bicycle tires.
