What is the Alcubierre “warp” drive?

Galactically Speaking on Instagram: "In Star Wars lore, a hyperdrive is the engine system that lets ships jump into hyperspace, a higher-dimensional realm that sits “alongside” normal space. In hyperspace: The normal speed limit of light doesn’t apply in the usual way. Distances between points in real space are effectively “shorter.” A ship follows a precisely calculated hyperspace lane, avoiding stars, planets, black holes, and gravity wells that would rip it out of hyperspace."

Warp Drive May Be More Feasible Than Thought, Scientists Say
