光走一年的距离是9.47x1012千米。伊卡洛斯号的速度是光速的十五分之一,我驾驶它在宇宙间航行已经超过十五年了。扣除停泊以及休假的时间,里程数大概已经超过一光年即9.47x1012千米了吧!诸君或许已经注意到我用“航行”、“停泊”来描述伊卡洛斯号——这列在星河轨道上高速飞行的宇宙列车。并不是我用字含糊草率,如果您曾有过在宇宙间航行的经验,一定能明白我如此描述的理由——搭乘宇宙列车的感觉,与其说是行进,不如说是漂浮。
Light walking distance of a year is 9.47x1012 km. The Icarus is one-fifteenth of the speed of light and I’ve been driving it for more than fifteen years in the universe. Deducting parking and leave time, the mileage has probably been more than a light year or 9.47x1012 km! Your may have noticed that I use “sailing”, “parking” to describe Icarus - This is a series of cosmic trains flying at high speed on the Xinghe orbit. It is not that I am using sloppy slogans. If you have ever had experience in navigating the universe, you must know the reason I have described so that the feeling of riding a cosmic train is not so much a journey as floating.
