Light travels at a speed which is about a million times faster than the speed of sound.In one second,light travels about 300,000km.But sound travels only 344m.You can get some idea of this difference by watching the start of a race.If you stand some distance away from the starter,you can see smoke comes from his gun before the sound reaches your ears.This great speed of light gives us some strange facts.Sunlight takes about 8 minutes to reach us.If you look at the light of the moon tonight,remember that the light left the moon 1.3 seconds before it reached you.The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km per minute.In some case,the light from one of tonight's stars started on its journey to you before you were bola.Thus,if you want to be honest,you cant say" The stars are shining to night"?You have to say "The stars look pretty.They were shining four years ago but their light has just reached Earth".

光的速度是大约一百万倍音速.在一个第二,光速约300000公里.但声音传播只有344米.你可以得到一些想法的差异通过观看比赛的开始.如果你站的距离起动器,您可以看到有烟从他的枪在声音到达你的耳朵之前.这个伟大的光速给了我们一些奇怪的事实.阳光大约需要8分钟到达美国.如果你看看今晚月亮的光,光记住离开月球1.3秒前收到.最近的恒星是如此遥远,从它的光,你可以看到今晚开始旅行对你四年前的速度每分钟近200万公里.在某些情况下,今晚的星星的光从一个之前你就踏上了旅程是流星锤.因此,如果你想说实话,你不能说“群星闪耀之夜”?你必须说“星星好看.他们闪亮的四年前,但刚刚光到达地球”.
