The warp drive: hyper-fast travel within general relativity

Описание: Disclaimer: This is not a speculative or popular-science presentation, but a pedagogical introduction grounded in the formalism of General Relativity.

This video provides a concise and rigorous overview of the theoretical foundations of the Alcubierre Warp Drive, designed for graduate-level students and researchers in General Relativity. The Alcubierre metric, introduced in 1994, describes a spacetime geometry that allows effective superluminal travel by contracting space in front of a warp bubble and expanding it behind, without violating local causality or the speed-of-light limit within the bubble.
