Alcubierre metric

The Alcubierre metric is a theoretical solution in general relativity that proposes a way to travel faster than light by manipulating space itself. Imagine a spaceship positioned in a "warp bubble" where space in front of it contracts and space behind it expands. This allows the ship to move great distances quickly without violating the laws of physics, as it doesn't move through space but rather shifts the space around it. Though purely theoretical and requiring exotic materials, it offers intriguing possibilities for future space travel concepts.
