Warp drives remain theoretical physics, not engineering, physicists stress
Original: 🔭 Warp drive is serious theoretical physics, not serious engineering. Alcubierre-style spacetime can be described by gen
Scientists are reiterating that Alcubierre-style warp drives, while describable within general relativity, remain firmly in the realm of theory rather than feasible engineering. A usable faster-than-light bubble would still require exotic forms of energy, exact control mechanisms, quantum stability, and would raise causality problems. The discussion aims to temper enthusiasm about faster-than-light travel, distinguishing legitimate spacetime solutions in physics from any near-term prospect of building an actual warp-capable spacecraft.
Why now: Renewed public interest in faster-than-light travel prompts physicists to clarify the gap between theoretical models and real engineering
