So let's now turn to Newton's universal law of gravity, and believe it or not, I think I even give you on the exam the gravitational force of Newton's universal law of gravity.
下面是牛顿的万有，引力定律，不管你信，或不信，在考试中，我出了关于万有引力，定律的题目。
Geologists can accurately predict where (but not when) the next earthquake will happen by using satellite gravity measurements and tracing ground deformation caused by earthquakes.
通过应用卫星重力测量仪器和追踪地震导致的地壳变形，地质学家能够准确的预测将要发生的地震会发生在什么地方(但不能测出什么时候发生)。
September: Stephen Hawking and American physicist Leonard Mlodinow argue in their book the Grand Design that gravity not God created the universe.
九月：史蒂芬·霍金和美国物理学家伦纳德·曼罗迪诺(Leonard Mlodinow)在他们合著的新书《大设计》(The Grand Design)中提出，是引力而非是上帝创造了宇宙。

这个理论把重力不是看做一种力，而是空间-时间的几何弯曲的结果。
A swimming pool can simulate the weightlessness of the ISS but not the moon's gravity-one sixth of Earth's.
游泳池能模拟国际空间站的失重状态，但不是月球的重力——地球的六分之一。
The reason is that galaxies do not behave in the way that they should if the laws of gravity are correct.
这是因为如果万有引力定律正确的话，星系本应依照该定律运行，可事实并非如此。
One of the most exciting ideas in modern physics is that gravity is not a traditional force, like electromagnetic or nuclear forces.
现代物理学最令人兴奋的观点之一是重力不是像电磁力和核力一样是传统力。
That makes it hard to argue that dark matter and dark energy are not real and to explain them away by, for example, modifying Einstein's theory of gravity.
这让那种认为暗物质和暗能量不存在的辩驳变得非常困难，更不可能抛开它们去解释任何事情，比如修改爱因斯坦的引力理论。
