论文摘要
我表明，由于恒星辐射压力，材料薄膜的材料薄膜远离银河系。无论是由原始磁盘中的灰尘凝结而自然产生的，还是通过技术文明人为地产生的，都会在银河系磁盘上方积累在银河系磁盘上方的年龄和悬停在黑色物质晕在标度高度设置的情况下。散射的星光的限制暗示该种群的含量低于星际中等质量的2x10^{-3}。
I show that interstellar films of material thinner than a micron, drift away from the Galactic plane as a result of stellar radiation pressure. Such films, whether produced naturally by dust coagulation in proto-planetary disks or artificially by technological civilizations, would accumulate over the age of the Milky-Way and hover above the Galactic disk at a scale-height set gravitationally by the dark matter halo. Limits on scattered starlight imply that this population carries a fraction below 2x10^{-3} of the interstellar medium mass.
