Two years later it would be travelling at 90 per cent of the speed of light.

在过两年，速度达到光速的90%， 远离太阳系； 发射四年之后，飞船开始了时间旅行。

The lorry driver noticed we were chasing him and he drove even quickly, that is of the speed of light.

罗里司机也看到我们在追他。他也跑得更快，犹如光的速度。

Einstein's famous equation, E=mc2, outlines how energy is equivalent to mass times the square of the speed of light.

这个道理可以参考著名的爱因斯坦质能方程式，E=mc2, 能量E是质量m乘以光速c的平方项。

Super-fast Internet connections let people watch movies and send huge amounts of information at the speed of light.

VOA: special.2010.09.01

You get 2.18 times 10 to the plus 6 meters per second, 1% which is about 1% of the value of the speed of light.

。18*10^6米每秒，得到的速度大概是光速的。

And then we have c, the speed of light, 2.998 times 10 to the 8 meters per second.

然后我们知道光速等于，2，998乘以10的8次方米每秒。

Has the charge of the electron or the speed of light altered over time, or has some combination of effects occurred?

ECONOMIST: Fundamental physics

That means its nucleus has a stronger positive charge and that, in turn, means the electrons orbiting the nucleus are more attracted to it and travel faster, at roughly 60% of the speed of light, compared with 35% for the electrons orbiting a tin atom.

The Large Hadron Collider (LHC), the world's biggest particle accelerator, uses a staggering 1, 200 tonnes of superconducting wire, similar to the sort used in MRI, in order to speed protons up to within a whisker of the speed of light and to collide them inside vast detectors, themselves stuffed with several hundred tonnes of superconducting materials.
