You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.
When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.
Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.

Silence is unnatural to man.He begins life with a cry and ends it in stillness.In between he does all he can to make a noise in the world, and he fears silence more than anything else.Even his conversation is an attempt to prevent a fearful silence.If he is introduced to another person, and a number of pauses occur in the conversation, he regards himself as a failure, a worthless person, and is full of envy of the emptiest headed chatterbox(喋喋不休的人).He knows that ninety-nine percent of human conversation means no more than the buzzing of a fly, but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure(蜡塑人像).
The aim of conversation is not, for the most part, to communicate ideas; it is to keep up the buzzing sound. There are, it must be admitted, different qualities of buzz; there is even a buzz that is as annoying as the continuous noise made by a mosquito (蚊子).But at a dinner party one would rather be a mosquito than a quiet person. Most buzzing, fortunately, is pleasant to the ear, and some of it is pleasant even to the mind. He would be a foolish man if he waited until he had a wise thought to take part in the buzzing -with his neighbors.
Those who hate to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish to talk. Very few human beings join in a conversation in the hope of learning anything new. Some of them are content if they are merely allowed to go on making a noise into other people's ears, though they have nothing to tell them except that they have seen two or three new plays or that they had food in a Swiss hotel. At the end of an evening during which they have said nothing meaningful for a long time, they just prove themselves to be successful conservationists.
