Warp Drive May Be More Feasible Than Thought, Scientists Say

"A warp drive to achieve faster-than-light
travel — a concept popularized in television's
Star Trek — may not be as unrealistic as
once thought, scientists say.

A warp drive would manipulate space-time
itself to move a starship, taking advantage of
a loophole in the laws of physics that prevent
anything from moving faster than light. A
concept for a real-life warp drive was
suggested in 1994 by Mexican physicist
Miguel Alcubierre, however subsequent
calculations found that such a device would
require prohibitive amounts of energy.

Now physicists say that adjustments can
be made to the proposed warp drive that
would enable it to run on significantly less
energy, potentially brining the idea back
from the realm of science fiction into
science."
