“Warp speed, Mr. Sulu!” With these words, Captain Kirk of the Starship Enterprise prepared his ship for faster-than-light travel while inspiring a generation of aspiring physicists who watched Star Trek from their sofas.
So it’s no surprise that in 1994, the theoretical physicist, Miguel Alcubierre, worked out how a warp drive might work in the real universe. The key feature of a warp drive is that it can propel a spaceship at superluminal speeds without the occupants experiencing huge acceleration.
Alcubierre’s idea was to create a flat region of spacetime inside a highly distorted bubble of spacetime that moves across the universe. The passengers sit in the flat region where the acceleration is zero, while the bubble as a whole, travels at superluminal speed, or at least exceedingly high velocity.
