前两天看到一篇(正经的天体力学)文章,越看越觉得所谓的Dyson Shell/Ring是没戏。文
章解释由于太阳系的混沌动力学,也会不断有小行星从 Kuiper Belt 和Astroid Belt跑
到太阳系内部来。
所以要建起个结构把太阳围起来,先得把有嫌疑的空间都腾空了,再装上一个Ringworld
式的防御系统避免小行星的碰撞。腾空Astroid Belt 都几乎是不可能的,这Kuiper
Belt就更远了......

Explanation: A day is just under 11 minutes long on 1998 KY26, a 30 meter wide,
fast-spinning, water-rich asteroid. This computer simulated view of its lumpy surface has a
resolution of about 3 meters and is based on radar and optical observations (click on the
image for a series of surface views). The observations were made shortly after the discovery
of the diminutive world which passed within about 800,000 kilom
