At this distance the optical light from stars is shifted, or stretched, to infrared wavelengths that can only be observed in outer space by Spitzer.
在这个距离，恒星的光源光被折射，或拉伸成红外波长，在外层空间只有斯皮策太空望远镜才能观测到。
To the astonishment of the entire world, the neutrinos clocked in 60 nanoseconds sooner than a light beam traveling the same distance would have done.

Seen from a distance on this sunny day, however, the bright autumn light made it hazy and golden, like a mirage in a fairy tale.
然而在这样一个晴朗的天气从一定距离看去，明亮的秋季光线使它看上去朦胧而辉煌，就像童话中的海市蜃楼。
The space-time ripples cause the distance measured by a light beam to change as the gravitational wave passes by, and the amount of light falling on the photodetector to vary.
时空涟漪使得用光束测量的距离像引力波通过那样变化，同时使得落在光电探测器上的光量发生变化。
