Warp drives are exotic solutions of general relativity that offer novel means of transportation. In this study, we present a solution for a constant-velocity subluminal warp drive that satisfies all of the energy conditions. The solution involves combining a stable matter shell with a shift vector distribution that closely matches well-known warp drive solutions such as the Alcubierre metric. We generate the spacetime metric numerically, evaluate the energy conditions, and confirm that the shift vector distribution cannot be reduced to a coordinate transformation. This study demonstrates that classic warp drive spacetimes can be made to satisfy the energy conditions by adding a regular matter shell with a positive ADM mass.

恒速物理曲速驱动解决方案

曲速驱动器是广义相对论的奇特解决方案，提供了新颖的运输方式。在这项研究中，我们提出了一种满足所有能量条件的恒速亚光速曲速驱动的解决方案。该解决方案涉及将稳定的物质壳与位移矢量分布相结合，该分布与众所周知的曲速驱动解决方案（例如阿尔库别尔度量）紧密匹配。我们以数值方式生成时空度量，评估能量条件，并确认移位向量分布不能简化为坐标变换。这项研究表明，通过添加具有正 ADM 质量的规则物质壳，可以使经典的曲速驱动时空满足能量条件。
