アルクビエレ・ドライブ (Warp Drive)
時空を歪ませることで光速を超える移動を可能にする理論モデル。
船自体が光速を超えて移動するのではなく、船を取り囲む「ワープ・バブル」ごと移動するため、アインシュタインの相対性理論に違反しません。

Based on the Alcubierre metric, the ship itself does not 'move' through space faster than light; rather, the space around it moves. This bypasses the Special Relativity limit because the expansion of spacetime itself is not restricted by the speed of light. However, the model requires 'negative energy' provided by exotic matter (Casimir effect) to keep the bubble stable. Recent refinements by Harold White suggest that a 'toroidal' bubble geometry could significantly reduce the energy requirements from Solar System levels to the mass-energy of a small spacecraft.
