As described by Eric W. Davis, senior research physicist at the Institute of Advanced Studies in Austin, Texas, and co-author of Frontiers of Propulsion Science, the warp drive can be envisaged as a means of "surfing" through spacetime:
Fill 'er Up with One Jupiter
Although Alcubierre's calculations showed that unimaginably huge amounts of energy would be needed to create this warp bubble, recently, Richard Obousy, co-founder and president of Icarus Interstellar (a key partner of the 100YSS), used our new understandings of quantum mechanics and applied them to the warp drive.
Obousy's approach is to manipulate dark energy - the mysterious force that appears to permeate the entire Universe, causing it to expand - in such a way that extra dimensions (as predicted by string theory) can facilitate the creation of a bubble of spacetime.
"Given that extra dimensions have not yet experimentally been shown to exist, and the idea that dark energy is an artifact of these extra dimensions is somehow related to these dimensions is clearly highly theoretical," Obousy told Discovery News, "however it provides us with an interesting perspective from which to examine the problem."
