The Alcubierre idea isn’t about speed, it’s about spacetime. The Alcubierre Drive suggests a ship sits inside a “warp bubble,” while space in front is compressed and space behind is stretched. The ship itself never locally breaks the theory of relativity, it’s space that moves, not the vessel. In theory, this creates effective faster-than-light travel without violating known laws of physics, but only if exotic energy or negative energy density can be controlled, something humanity has never achi
