When plants shoot on the earth, their stems grow away from the gravity (the force that keeps your feet on the ground), and so they always shoot upwards.
当植物在地面上生长时，它们的茎生长得方向与重力相反（重力是让你的脚留在地面上的力量），因此它们总是向上生长。
The moon's gravity is a sixth as strong as the earth's, so Chang'e-4's experiment was a test: would the earth plants know which way was up on the moon?

In this method, when one star passes in front of another, as seen from Earth, the nearer star's gravity ACTS like a lens, bending and magnifying the more distant star's light.
当天文学家用这种方法从地球上观测到一颗恒星在另一颗恒星前“走过”时，距地球较近的这颗恒星的重力就如同一个镜头，将较远的那颗恒星的光弯曲并放大。
Lockheed's plan involves using the combined gravity of the Earth and the Moon to ensure that its craft hovers on the same spot, within sight of both planets.

Soon after taking off from Florida, LCROSS used gravity to slingshot itself into a wide orbit around the Earth that would eventually coincide with the moon.
从佛罗里达起飞后不久，LCROSS利用重力将自身弹射入一更大的绕地轨道，最终将从那里撞向月球。
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。
When that light travels to a new environment, say to a telescope on Earth, where there is comparatively lower gravity, and time moves more slowly, the light's frequency will decrease.
当光运行而到达一个新的环境时，譬如到达了地球上的某个望远镜，由于地球上只有较小的引力，时间的流逝就会变慢，由此光的频率就会降低。
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。
But gravity lessens with distance and this means that the pull from the Moon is stronger on the side of Earth that is facing the Moon.
但是，引力随距离增大而减小，这意味着月球施加在朝向自己那一面的地球部分的拉力要大些。
For asteroids too big for a robot to handle a large spacecraft could fly near the object to act as a gravity tractor that deflects the asteroid's trajectory sending it toward Earth.
对于机器人无法捕获的较大的行星，则派一艘大型宇宙飞船接近，利用重力牵引使行星偏离轨道，飞向地球。
The planet – Gliese g – appears to have an atmosphere and gravity similar to that of Earth.
这颗行星—格里斯g—大气和重力与地球相似。
Messenger and is using gravity from Earth and Venus to slightly alter its orbit over time before it moves into Mercury's orbit in March 2011.
预计信使号飞船将于2011年3月进入水星的运行轨道，在这之前它要借助来自地球和金星的引力，稍微调整一下自己的轨道。
After four or five minutes gravity will begin to drag the Enterprise back down to earth.
4到5分钟后，重力将开始把飞船拉回地球。
Once an asteroid starts approaching Earth, it will do so again and again in an orbital waltz driven by gravity as both bodies travel around the Sun.
一旦某颗小行星开始接近地球，它会在重力作用下，像跳华尔兹一样，一次又一次接近地球，因为它和地球一样也绕太阳运行。
They say that well before dinosaurs or, really, much of anything roamed the earth, rivers were just vast expanses of water heeding only gravity and heading straight to sea.
他们说在恐龙及地球上有任何走动的生物之前，河流只是非常宽阔的水面，只是服从重力的影响，直接流向大海。
The satellite traveling in the orbit is always escaping from the earth only to be pulled back by gravity.
在轨道上运行的卫星总是要飞离地球，而结果总是被地心引力拉回来。
For asteroids too big for a robot to handle, a large spacecraft could fly near the object to act as a gravity tractor that deflects the asteroid's trajectory, sending it toward Earth.
如果行星对于机器人来说比较大的话，也可以使用一艘大型的宇宙飞船将行星拉离原有的轨道，而向着地球的方向前进。
They say that well before dinosaurs or, really, much of anything roamed the Earth, rivers were just vast expanses of water heeding only gravity and heading straight to sea.
典型的古代的河流只是宽阔的、像平板一样的水流。 《地质学》和《地球科学评论》上的一项最新研究说我们应该感谢最初的那些陆生植物，它们使河流变得弯曲了。
We have explained this being due to light in the red spectrum bending readily, so red light is bent first over the horizon by the gravity of Earth where light in the other spectrums is not so bend.
我们解释过这是由于红色光谱更容易弯曲，所以当其他光线还没怎么样时，红光首先由于地球的引力而沿着地球的曲线弯曲。
No, seriously. I've always dreamed of traveling in space, floating in zero gravity, gazing down on the Earth.
