Overview
- The Advanced Propulsion Laboratory published a theoretical warp-drive model in Classical and Quantum Gravity that largely removes the need for negative energy.
- This approach builds on the 1994 Alcubierre framework by proposing localized, controllable spacetime bubbles instead of exotic negative-energy matter.
- The paper describes a physically consistent design but acknowledges that the required mass and energy are still enormous at present.
- Popular Mechanics reports that Miguel Alcubierre has endorsed the new model, adding visibility to the work though it remains speculative.
- Previous efforts such as NASA’s Eagleworks have explored warp-like propulsion without practical breakthroughs, and the new concept is still considered a far-future prospect.
