什么是黑洞？
就是在宇宙中有那么一些點(diǎn)，這些點(diǎn)的體積趨向于零而密度變得無窮大，由于具有強(qiáng)大的吸引力，物體只要進(jìn)入離這個(gè)點(diǎn)一定距離的范圍內(nèi)，就會(huì)被這個(gè)強(qiáng)大的引力吸收掉，連光線也不例外。因此任何進(jìn)入這個(gè)范圍的物體都無法再逃出來，就是說，沒有任何信號(hào)能夠從這個(gè)范圍內(nèi)傳出，因此這個(gè)范圍的界限被稱作視界，里面的情形人類無法看到。所以科學(xué)家給它起了個(gè)名字叫黑洞，英文就是black hole。 一顆燃燒盡了的恒星由于自身的重力而不斷坍縮，最后就會(huì)形成黑洞。
歷時(shí)30年霍金改觀點(diǎn) 稱黑洞能“吸”能“吐”
從事宇宙黑洞研究近三十年的世界天體物理學(xué)泰斗斯蒂芬?霍金在前不久承認(rèn)“黑洞悖論”有誤之后，21號(hào)，他在愛爾蘭都柏林舉行的一個(gè)學(xué)術(shù)研討會(huì)上終于就自己的新發(fā)現(xiàn)向外界進(jìn)行了詳細(xì)闡述。
黑洞是宇宙中引力極強(qiáng)的區(qū)域。19世紀(jì)70年代，霍金首次提出黑洞能夠輻射能量的理論，但是在引入這一理論的同時(shí)，霍金也制造了物理學(xué)上的一個(gè)巨大難題，因?yàn)樗J(rèn)為
黑洞輻射不包含以前吸入物質(zhì)的相關(guān)信息，而且隨著黑洞的消失，曾經(jīng)存在的黑洞的相關(guān)信息也會(huì)消失于無形。這與量子力學(xué)中認(rèn)為物質(zhì)信息不會(huì)完全消失的理論相矛盾。對(duì)此，過去近30年來，霍金的解釋是：黑洞中的量子運(yùn)動(dòng)是一種特殊情況，這種說法受到了許多科學(xué)家的質(zhì)疑。
如今，霍金終于改變了觀點(diǎn)，在當(dāng)天召開的學(xué)術(shù)研討會(huì)上，霍金說，根據(jù)他的最新發(fā)現(xiàn)，黑洞并非只是吞噬物質(zhì)。除了會(huì)在星系形成的過程中扮演重要角色外，在經(jīng)過一段相當(dāng)漫長(zhǎng)的時(shí)間后，黑洞也會(huì)把一些曾被它吸入的物質(zhì)信息向外界釋放出來。
霍金的最新闡述被不少人稱為黑洞理論的一個(gè)重要逆轉(zhuǎn)。美國加州理工學(xué)院的理論物理學(xué)家約翰?普雷斯基就是其中之一。20多年前，霍金提出黑洞輻射理論時(shí)，普雷斯基就一直堅(jiān)持物質(zhì)信息不會(huì)完全消失，當(dāng)時(shí)兩人還因此打賭。所以，在當(dāng)天結(jié)束演講后，霍金將一本百科全書贈(zèng)予普雷斯基，作為打賭輸了的代價(jià)，而普雷斯基則獲得了全場(chǎng)的熱烈掌聲。
Black holes
(1) What is a black hole? Well, it's difficult to answer this question, since the terms we would normally use to describe a scientific phenomenon are inadequate here. Astronomers and scientists think that a black hole is a region of space (not a thing ) into which matter has fallen and from which nothing can escape---- not even light. So we can't see a black hole. A black hole experts a strong gravitational pull and yet it has no matter. It is only space ---- or so we think . how can this happen?
(2) The theory is that some stars explode when their density increases to a particular point; they collapse and sometimes a supernova occurs. Form earth , a supernova looks like a very bright light in the sky which shines even in the daytime. Supernovae were reported by astronomers in the seventeenth and eighteenth centuries. Some people think that the Star of Bethlehem could have been a supernova. The collapse of a star may produce a White Dwarf or a neutron star--- a star , whose matter is so dense that it continually shrinks by the force of its own gravity. But if the star is very large (much bigger than our sun) this process of shrinking may be so intense that a black hole results. Imagine the earth reduced to the size of a marble, but still having the same mass and a stronger gravitational pull, and you have some idea of the force of a black hole. Any matter near the black hole is sucked in. It is impossible to say what happens inside a black hole. Scientists have called the boundary area around the hole the " event horizon." We know nothing about events which happen once objects pass this boundary. But in theory, matter must behave very differently inside the hole.
(3) For example , if a man fell into a black hole, he would think that he reached the center of it very quickly. However an observer at the event horizon would think that the man never reached the center at all. Our space and time laws don't seem to apply to objects in the area of a black hole. Einstein's relativity theory is the only one which can explain such phenomena , so that there is no " absolute" time and space depend on the position of the observer. They are relative. We do not yet fully understand the implications of the relativity theory; but it is interesting that Einstein's theory provided a basis for the idea of black holes before astronomers started to find some evidence for their existence. It is only recently that astronomers have begun specific research into black holes. In August 1977, a satellite was launched to gather data about the 10 million black holes which are thought t be in the Milky way. And astronomers are planning a new observatory to study the individual exploding stars believed to be black holes.
(4) The most convincing evidence of black holes comes from research into binary star systems. Binary stars, as their name suggests ,are twin stars whose position in space affects each other. In some binary systems, astronomers have shown that there is an invisible companion star, a "partner" to the one which we can see in the sky. Matter from the one we can see is being pulled towards the companion star. Could this invisible star, which exerts such a great force , be a black hole? Astronomers have evidence of a few other stars too, which might have black holes as companions.
(5) The story of black holes is just beginning . Speculations about them are endless. There might be a massive black hole at the center on our galaxy swallowing up stars at a very rapid rate. Mankind may one day meet this fate. On the other hand, scientists have suggested that very advanced technology could one day make use of the energy of black holes for mankind. These speculations sound like science fiction. But the theory of black holes in space is accepted by many serious scientists and astronomers .they show us a world which operates in a totally different way from our own and they question our most basic experience of space and time.
Read the passage carefully and choose the best answer for the following questions
1) Black holes are related to ____
A.geography B. astronomy C. physics D. economic
2) A black hole is ____
A.a dark star B. a large heavenly body

5) according to Einstein's relativity theory, there is no "absolute " time and space. Is it true or false?
A. true B. false
6) which of the following statements is not true? The story of black holes in space____
A. is accepted by many serious scientists and astronomers
B. has to some extent been proved by research into binary star system
C. is questioning our basic idea of space and time
D. Sounds like science fiction
7) according to the passage , our earth may be swallowing by the black hole one day, is it true or false ?
A.true B. false
8) according to the passage , the human being one day may make use of the energy of black hole by advanced technology. Is it true or false?
