That might sound confusing - seeing as how the Sun is so much bigger than the Moon, but remember - gravity decreases with distance - and the Sun is much farther away from Earth than the Moon.
听起来可能有些令人困惑——明明太阳是远远大于月球的，但请记住——引力随距离减小——比起地球与月球的距离，太阳遥远得多。
On our spherical Earth, gravity pulls "down" us toward the planet's center of mass. So on a flat surface, we naturally stand up straight.
在我们地球上，重力会把我们拉向星球的质量中心，因此在平坦的地表，我们自然站得很直。
Gran Sasso and CERN are at different distances from the center of the Earth, so the force of gravity varies slightly between the two LABS.
由于格兰·萨索与欧洲核子研究中心，这两个位置离地球中心的距离并不一样，所以这两个实验室里的重力也稍许有所差别。
All the gravity of all the mass in the cosmos should have been pulling the universe back inward, just as gravity pulls a ball back down to Earth after it's been thrown into the air.
宇宙中每一物体的每个引力都会对宇宙产生一个指向物体本身的拉力，就像在重力作用下，抛向空中的球会被拉回地面。
