Kurzgesagt 详细解析了 Shkadov thruster 和 Caplan thruster 等恒星发动机（stellar engines）。这类宏构想能在数百万年的时间尺度上推动太阳和整个太阳系在银河系中穿梭，从而规避宇宙危险并抵达全新星域。
为什么 HN 推它
每当 Hacker News 讨论起移动太阳系、卡尔达肖夫文明（Kardashev civilizations）或世代飞船时，大家总会翻出这期视频，不少人将其誉为 Kurzgesagt 制作的最精彩的一期。
「在 Kurzgesagt 制作的所有视频里，这是我最喜欢的一部。」HN 网友原话：Out of every video Kurzgesagt has ever produced, my favorite is this one
英文原摘要（HackerTube / Claude 整理）
Kurzgesagt explains stellar engines such as the Shkadov thruster and Caplan thruster, which could move the Sun and solar system across the galaxy over millions of years to avoid hazards and reach new regions.
HN returns to it whenever moving the solar system, Kardashev civilizations or generation ships come up, with some calling it their favorite Kurzgesagt video.
HN 上的提及
The channel then created a stunning video to illustrate the device, which it dubbed the Caplan Thruster
I was amazed to know that theoretically we can move our solar system.
Out of every video Kurzgesagt has ever produced, my favorite is this one
Kurzgesagt did a video on stellar engines (which can be much less exotic than wormholes)
it even seems possible that we can viably transport our entire solarsystem
