**课程名称：** 曲速引擎物理学：为曲速飞行做准备 **课程概述：** 本课程将深入探讨曲速引擎这一理论上的超光速（FTL）航天器推进系统。曲速引擎能够让航天器以远超光速的惊人速度进行旅行。与其他一些超光速技术（如跳跃引擎或超空间引擎）不同，曲速引擎并非实现瞬时旅行，而是涉及一段可测量的时间经过，这在曲速飞行的概念中尤为重要。处于曲速速度的航天器仍能与“正常空间”中的物体进行互动。 爱因斯坦的狭义相对论指出，具有非零静止质量的物质物体（与光子不同）不可能达到光速。要让一个物质物体超越光速，需要无限的动能才能达到光速。曲速引擎在科幻作品中正是为了规避这一限制，从而能够构建银河系尺度的宏大故事。 除了让飞船在曲速场中滑行穿越空间之外，本课程还将探讨空间折叠的概念。空间折叠意味着将时空的两个点直接连接，从而实现瞬时转换。中间的空间被简单地折叠进一个更高维度的超空间或亚空间。 **课程大纲：** 无
A warp drive is a theoretical faster-than-light (FTL) spacecraft propulsion system. A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude. In contrast to some other FTL technologies such as a jump drive or hyperdrive, the warp drive does not permit instantaneous travel between two points, but rather involves a measurable passage of time which is pertinent to the concept. Spacecraft at warp velocity would continue to interact with objects in "normal space".Einstein's theory of special relativity states that speed of light travel is impossible for material objects that, unlike photons, have a non-zero rest mass. The problem of a material object exceeding light speed is that an infinite amount of kinetic energy would be required to travel at exactly the speed of light. Warp drives serve to circumvent this limitation in fiction to facilitate stories set at galactic scales.In addition to the possibility to let a spaceship glide through space in a warp field, there is also space folding. Spatial folding means that two points of space-time are directly connected and an instantaneous change takes place. The space between is simply folded into a higher-dimensional hyperspace or subspace.
