La matematica del motore a curvatura 28.11.12

La NASA è al lavoro sulla teoria di un motore a curvatura per piegare lo spazio-tempo e superare la velocità della luce. Per i non addetti ai lavori la velocità warp di Star Trek.

The idea came to White while he was considering a rather remarkable equation formulated by physicist Miguel Alcubierre. In his 1994 paper titled, "The Warp Drive: Hyper-Fast Travel Within General Relativity," Alcubierre suggested a mechanism by which space-time could be "warped" both in front of and behind a spacecraft.

Michio Kaku dubbed Alcubierre's notion a "passport to the universe." It takes advantage of a quirk in the cosmological code that allows for the expansion and contraction of space-time, and could allow for hyper-fast travel between interstellar destinations. 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. ...

In terms of the engine's mechanics, a spheroid object would be placed between two regions of space-time (one expanding and one contracting). A "warp bubble" would then be generated that moves space-time around the object, effectively repositioning it -- the end result being faster-than-light travel without the spheroid (or spacecraft) having to move with respect to its local frame of reference.
