This phenomenon, predicted by Einstein's theory of general relativity, causes light to curve as it flies through space-time that has been dented by the gravity of large bodies of mass.
Because light travels in a straight line through the contours of space-time, a light beam will curve where space-time curves, this curving was first measured in 1919.
因为光沿时空走直线，所以光线在时空弯曲的地方会弯曲。这现象在1919年首次被观测到。

We detected the chopped light using this function and drawed the time-resolved curve by the plot program compiled by ourselves. The results fit with our design.
