The ripples are gravitational waves.(這些波動就是重力場波。)

Gravitational waves can't exist in one or two-dimensional space.(在一維或二維空間，引力波無法存在。)

Their loveliness masks the toll exacted by the gravitational pull of their large bodies and the strain of daily survival.(他們的可愛掩飾了引力對巨大身體的拖累和日常生活的艱辛。)

The earth gravitational potential was developed up to 11th degree and 11th order for all of zonal and tesseral harmonic terms.(地球重力勢對帶諧、扇諧和田諧項都展開到了第11次和第11階。)

This is the gravitational potential energy.(這是重力勢能。)

Under the control of the Sun's gravitational force, each planet maintains an elliptical orbit and all of them travel in the same direction.(在太陽引力的控制下，每個行星都維持在一條橢圓形的軌道上，并按照相同的方向移動。)

We shift the gravitational center of it.(我們轉移他的重力中心。)

There seems to be a kind of gravitational pull toward God.(似乎有一種引力把我拉向了上帝。)

Notice that the gravitational potential energy increases.(注意，這里，重力勢能是增加的。)

Is that causes by gravitational attraction?(這是由萬有引力作用產生的嗎？)
