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 s
A. we will notice that it is not moving
B. we cannot tell whether or not it still exists
C. it will be brighter than the moon
D. it is four years that the light we can see will reach us

Burn rate is the speed at which a startup business consumes money. My rate was $75,000 a month. Four months after my company was set up, I had only a quarter of the starting capital left in the bank.
Looking for guidance, I went to talk to my friend, Arthur Walworth about my new venture.
"Times of great change always bring out the risk-takers," he said. "And they leave winners and losers. My grandfather invested a lot of money in a project of Thomas Edison’ s that ended up in failure."
