Warp-speed travel at faster-than-light speeds is not impossible--as Einstein implied--but only requires sidestepping the prohibition by stretching space itself, at least according to modern string-theory physicists. Now that the possibility is known, how long will it be before somebody figure out how to implement it? I would guess about 20 years. R.C.J.
With the latest installment of the Star Trek franchise packing theaters, researchers are again speculating about the feasibility of building a faster-than-light "warp drive" similar to the one powering Star Trek's "Enterprise" star ship. Researchers at Baylor University (Waco, Texas) claim that dark energy--the force causing the universe to expand--could power a warp drive by expanding the fabric of space behind the ship while simultaneously contracting space ahead of it. The scheme could theoretically enable a ship to traverse light years in distance without violating Einstein's prohibition on faster-than-light travel.
