- 光速：电磁辐射在真空中传播的速度，是一个基本的物理常数，其数值由国际公约确定为每秒299,792,458米，符号为c。
- n.
1 the speed at which light travels in a vacuum; the constancy and universality of the speed of light is recognized by defining it to be exactly 299,792,458 meters per second 同义词：light speed??/??c
- 1
We think of relativity's effects on time as occurring at near light speeds or in the presence of crushing gravitational fields. 我们一般认为只有在接近光的速度或存在着支离破碎的引力场的情况下，才要考虑相对论对时间的影响。 - 2
These particles of light are the fastest things in the universe, so an optical computer could theoretically process information at speeds that make even a supercomputer look glacial. 光粒子是宇宙中速度最快的东西，所以一台光学计算机在理论上可以在计算机启动前就能处理完信息。 - 3
At some point they will be travelling so fast that the way they bond will be affected by Albert Einstein's theory of relativity, which departs from classical theories at speeds close to that of light. 从某种意义上看，根据爱因斯坦相对论(当达到接近光速的速度时，相对论就背离了经典理论)，电子运动速度加快，电子间相互结合的方式就会受影响。
