A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!

A few days ago I asked my sons’ governess（女家庭教师）Julia to come into my study. “Be seated, Julia, ”I said, “Let’s settle our accounts. I guess you most likely need some money, but maybe you’re too polite to mention it. Now then, we agreed on thirty dollars a month...”

　　“Forty.”

　　“No, thirty. I made a note of it. I always pay our governess thirty. Well, um, you’ve been here two months, so...”

　　“Two months and five days.”

　　“Exactly two months. I made a special note of it. That means you have sixty dollars coming to you. Take off nine Sundays... you know you didn’t work with Tom on Sundays, you only took walks. And three holidays... ”Julia was biting her finger nail nervously, her face red, but - not a word.

　　“Three holidays, therefore take off twelve dollars. Four days Tom was sick and there were no lessons, as you were occupied only with Dick. Three days you had a toothache and my wife gave you permission not to work after lunch. Twelve and seven - nineteen. Take nineteen off ... that leaves. hmm.... forty one dollars. Correct？”

　　Julia’s left eye reddened with tears welling up. Her chin trembled; she coughed nervously and blew her nose, but - still not a word.

　　“Around New Year’s Day you broke a teacup and a saucer; take off two dollars. The cup cost more, it was a treasure of the family, but- forget it. When didn’t I take a loss! Then, due to your neglect （疏忽）, Tom climbed a tree and tore his jacket; take away ten. Also due to your carelessness the maid stole Dick’s shoes. You ought to watch everything! You get paid for it. So, that means five more dollars off. The tenth of January I gave ten dollars.”

　　“You didn’t. ”sobbed Julia.

　　“But I made a note of it.”

　　“Well... if you say so.”

　　“Take twenty seven from forty one -that leaves fourteen.”

　　Both her eyes were filled with tears. Beads of sweat stood on the thin pretty little nose. Poor girl!

　　“Only once was I given any money,” she whispered, her voice trembling, “and that was by your wife. Three dollars, nothing more.”

　　“Really? You see now, and I didn’t know that! Take three from fourteen.. leaves eleven. Here’s your money, my dear. Three, three, three, one and one. Here it is !”

　　I handed her eleven dollars. She took them and pocketed them.

　　“Merci （法语: 谢谢）,”she whispered.

　　I jumped to my feet and started pacing the room. I was overcome with anger. “For what, this - ‘merci’?” I asked.

　　“For the money. ”

　　“But you know I’ve cheated you - robbed you ! I have actually stolen from you ! Why this‘merci’？”

　　“In my other places they didn’t give me anything at all.”

　　“They didn’t give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you... I m going to give you all the eighty dollars! Here they are in the envelope all ready for you... Is it really possible to be so spineless （懦弱）?Why didn’t you protest? Why were you silent? Is it possible in this world to be without teeth and claws（爪）—to be such a fool?”

　　Embarrassed, she smiled. And I could read her expression,“It is possible.”

　　I asked her pardon for the cruel lesson and, to her great surprise, gave her the eighty dollars. She murmured her little“merci”several times and went out. I looked after her and thought,“How easy it is to crush the weak in this world !”

One hot night last July, when our new baby wouldn’t or couldn’t sleep, I tried everything I could think of : a warm bottle, songs gentle rocking. Nothing would settle him. Guessing that I had a long night ahead of me, I brought a portable TV into his room, figuring that watching the late movie was as good a way as any to kill of the hours till dawn. To my surprise, as soon as the TV lit up, the baby quieted right down, his little eyes focused brightly on the tube. Not to waste an opportunity for sleep, I then tiptoes out of the room, leaving him to watch the actors celebrate John Bellushi’s forty-fifth birthday.
My wife and I heard none of the baby that night, and the next morning when I went into his room, I found him still watching TV himself.
I found in my baby’s behavior a symbol of the new generation. My wife and I had given him some books to examine, but he merely spit upon them. When we read to him, he did not feel comfortable. And so it is in the schools. We find that our students don’t read and they look down upon reading and scold those of us who teach it. All they want to do is watch TV. After this experience with the baby, however, I have reached a conclusion: “Let them watch it!” If television is that much more attractive to children than books, why should we fight about it? Let them watch it all they want!
