Since Miguel Alcubierre first sketched a geometry permitting faster-than-light travel in 1994, physicists have wrestled with a quiet but persistent question: does mathematical elegance imply physical reality? A 2026 study by Thomas Buchert and Antony Frackowiak brings that question into sharp relief, demonstrating that when a theoretical warp bubble is freed from artificial constraints and allowed to evolve on its own terms, its field collapses into incoherence — trajectories crossing into caustics, the smooth fabric of the description tearing apart. The finding does not close the door on warp
