To Boldly Go

On the making of a warp ship that could allow travel to interstellar space in a matter of weeks rather than centuries (amazing!):

"Essentially, the empty space behind a starship would be made to expand rapidly, pushing the craft in a forward direction — passengers would perceive it as movement despite the complete lack of acceleration.

White speculates that such a drive could result in “speeds” that could take a spacecraft to Alpha Centauri in a mere two weeks — even though the system is 4.3 light-years away."
