We here on Earth obey the same laws of light and gravity as someone in a far off corner of the universe.

我们在地球上的所依从的有关光和引力的规律同它们在遥远的宇宙角落里是一模一样的。

Using Newton's concepts of light and gravity, they reasoned that the gravitational pull of a massive star could grow large enough to prevent light from escaping.

利用牛顿关于光和重力的理论，他们分析出当一个星球足够大的时候，其引力效应可以将光线完全捕获。

When Newton discovered gravity, and when Thomas Edison invented the light bulb, their curiosity was greatly satisfied.

当牛顿发现了万有引力、托马斯·爱迪生发明了灯泡时，他们的好奇心都得到了极大的满足。

The unique collection of notes, including workings behind Newton's theories on gravity and light, were revealed on Wednesday at Sotheby's auction house, London.

There is, however, scope for new laws of gravity that affect light and heavy objects differently, or involve a modification of the concept of inertia.

ECONOMIST: A space oddity

Einstein's launch into fame, which occurred when measurements made during a 1919 eclipse confirmed his prediction of how much gravity bends light, coincided with, and contributed to, the birth of a new celebrity age.
