演說(shuō)題目：Questioning the universe
演說(shuō)者：Stephen Hawking
There is nothing bigger or older than the universe. The questions I would like to talk about are: one, where did we come from? How did the universe come into being? Are we alone in the universe? Is there alien life out there? What is the future of the human race?
沒(méi)什么比宇宙更廣大更久遠(yuǎn)的了。你們的問(wèn)題中我想聊一下的是：你我何從?宇宙何來(lái)?宇宙中就只有我們?有外星異生物么?人類的未來(lái)將會(huì)如何?
Up until the 1920s, everyone thought the universe was essentially static and unchanging in time. Then it was discovered that the universe was expanding. Distant galaxies were moving away from us. This meant they must have been closer together in the past. If we extrapolate back, we find we must have all been on top of each other about 15 billion years ago. This was the Big Bang, the beginning of the universe.
上世紀(jì)20xx年代之前，所有人都以為宇宙基本上是處于穩(wěn)態(tài)，流金歲月，持恒不變。之后我們發(fā)現(xiàn)原來(lái)宇宙正在膨脹中。遼遠(yuǎn)星系一直飛離我們，這意味著它們必定曾相靠近。我們?nèi)敉笸扑悖蜁?huì)發(fā)現(xiàn)我們必都曾於約150億年前，互相堆疊在一起。正是這 "霹靂大爆炸" ——宇宙之起始。
But was there anything before the Big Bang? If not, what created the universe? Why did the universe emerge from the Big Bang the way it did? We used to think that the theory of the universe could be divided into two parts. First, there were the laws like Maxwell's equations and general relativity that determined the evolution of the universe, given its state over all of space at one time. And second, there was no question of the initial state of the universe.
然而大爆炸前可有什么嗎?若是沒(méi)有，又是什么創(chuàng)造宇宙呢?宇宙緣何要從大霹靂中冒出呢?過(guò)往我們都認(rèn)為宇宙論可分成兩部分，首先，是定律。像“麥克斯韋方程組”'和 “廣義相對(duì)論”以其于同一刻設(shè)定整個(gè)時(shí)空之狀態(tài)，而決定了宇宙之演化進(jìn)程。次之，是對(duì)宇宙雛形的疑問(wèn)。
We have made good progress on the first part, and now have the knowledge of the laws of evolution in all but the most extreme conditions. But until recently, we have had little idea about the initial conditions for the universe. However, this division into laws of evolution and initial conditions depends on time and space being separate and distinct.
第一部分我們?nèi)〉昧己眠M(jìn)展，除了“至極端境況”'以外。現(xiàn)在已對(duì)演化規(guī)律于所有境況下之進(jìn)程有所掌握。可直至最近，我們?nèi)詫?duì)宇宙初生當(dāng)時(shí)之周圍條件不甚了了。然而，這演化律及初始條件之界分，乃囿于"時(shí) 空分明"之概念內(nèi)。
Under extreme conditions, general relativity and quantum theoryallow time to behave like another dimension of space. This removes the distinction between time and space, and means the laws of evolution can also determine the initial state. The universe can spontaneously create itself out of nothing.
而於極端條件下，廣義相對(duì)論及量子論容許“時(shí)間”如同“空間”的另一維度般運(yùn)作。這就將“時(shí).空”之間區(qū)別移除了，即是說(shuō)演化律 亦可決定初始狀態(tài)。宇宙可以由無(wú)變有自我創(chuàng)生!
Moreover, we can calculate a probability that the universe was created in different states. These predictions are in excellent agreement with observations by the WMAP satellite of the cosmic microwave background, which is an imprint of the very early universe. We think we have solved the mystery of creation. Maybe we should patent the universe and charge everyone royalties for their existence.
我們甚至可以計(jì)算出宇宙在不同情況下誕生的可能性。這些推論與WMAP衛(wèi)星所觀測(cè)到的宇宙微波背景輻射(即大爆炸之痕跡)相當(dāng)一致。我們相信已勘破了創(chuàng)造奧秘或許我們應(yīng)將“宇宙”給注冊(cè)，然后向每個(gè)生存于世的人收“生活費(fèi)”。
I now turn to the second big question: are we alone, or is there other life in the universe? We believe that life arose spontaneously on the Earth, so it must be possible for life to appear on other suitable planets, of which there seem to be a large number in the galaxy.
現(xiàn)在我轉(zhuǎn)到第二個(gè)大問(wèn)題去，宇宙中就只有我們，還是另有其它生物?我們相信生命從地球自我衍生，故此生命確有可能出現(xiàn)於其它合適星球——星河中看來(lái)可有不少呢。
But we don't know how life first appeared. We have two pieces of observational evidence on the probability of life appearing. The first is that we have fossils of algae from 3.5 billion years ago. The Earth was formed 4.6 billion years ago and was probably too hot for about the first half billion years. So life appeared on Earth within half a billion years of it being possible, which is short compared to the 10-billion-year lifetime of a planet of Earth type. This suggests that the probability of life appearing is reasonably high. If it was very low, one would have expected it to take most of the ten billion years available.
但我們?nèi)晕磾囃ㄉ侨绾紊桑簩?duì)於生命誕生的可能契機(jī)，我們有兩項(xiàng)觀測(cè)得來(lái)的佐證。首先我們有來(lái)自35億年前的海藻化石。地球于46億年前形成，頭約5億年相信仍太熱了。故此生命于其變得可能后的5億年間方出現(xiàn)，這相對(duì)于像地球之類百億年期的星體，只算是一段短時(shí)間。這意味著生命出現(xiàn)的概率是頗高的。若是低的話，就可預(yù)期要花盡百億年的絕大部分才會(huì)出現(xiàn)。
On the other hand, we don't seem to have been visited by aliens. I am discounting the reports of UFOs.Why would they appear only to cranks and weirdos? If there is a government conspiracy to suppress the reports and keep for itself the scientific knowledge the aliens bring, it seems to have been a singularly ineffective policy so far. Furthermore, despite an extensive search by the SETI project, we haven't heard any alien television quiz shows. This probably indicates that there are no alien civilizations at our stage of development within a radius of a few hundred light years. Issuing an insurance policy against abduction by aliens seems a pretty safe bet.
另一方面，我們似乎從未見有外星人到訪。我不信那些什么“不明物體的報(bào)導(dǎo)”。它們干嗎要單向那些古古怪怪的人現(xiàn)身呢?若真有一個(gè)甚麼政府陰謀要將報(bào)導(dǎo)打住，從而將外星人所帶來(lái)之科學(xué)識(shí)據(jù)為己有，那可真像個(gè)既離奇，亦從未見效的舉措。再說(shuō)，即便SETI計(jì)劃已進(jìn)行廣泛探索，我們還沒(méi)有收聽到任何外太空電視答問(wèn)節(jié)目。這可能昭示在我們現(xiàn)階段文明發(fā)展之方圓數(shù)百光年范圍之內(nèi)，并沒(méi)有其它外星異文化。賣保險(xiǎn)給那些怕被外星人綁架的人，看來(lái)是個(gè)不錯(cuò)的.選擇。
This brings me to the last of the big questions: the future of the human race. If we are the only intelligent beings in the galaxy, we should make sure we survive and continue. But we are entering an increasingly dangerous period of our history. Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill. But our genetic code still carries the selfish and aggressive instincts that were of survival advantage in the past. It will be difficult enough to avoid disaster in the next hundred years, let alone the next thousand or million.
這送我到了最后一個(gè)大問(wèn)題：人類的前途。若我們是星河里唯一智能生物，就必須確保自己能存活并延續(xù)下去。但我們正邁入歷史中一個(gè)愈發(fā)危險(xiǎn)的時(shí)段。我們的人囗和對(duì)地球有限資源的耗用，正以幾何級(jí)數(shù)增長(zhǎng)，相隨的是我們將環(huán)境或弄好或弄垮的技術(shù)才能，至于我們的基因指令則仍帶著那自私和好斗的本質(zhì)，這或有利于我們過(guò)往求存，卻又讓我們于往后數(shù)百年內(nèi)人禍難逃。更別說(shuō)未來(lái)千百萬(wàn)年了。
Our only chance of long-term survival is not to remain inward-looking on planet Earth, but to spread out into space. The answers to these big questions show that we have made remarkable progress in the last hundred years. But if we want to continue beyond the next hundred years, our future is in space.That is why I am in favor of manned — or should I say, personned — space flight.
我們長(zhǎng)活下去的唯一機(jī)會(huì)，不是一直呆著在地球而是沖出太空去。這些大問(wèn)題之解答顯示我們于過(guò)去數(shù)百年取得可觀進(jìn)展。可若要超越未來(lái)數(shù)百年，們的前途在于太空。正因此，我較傾向于 "人" 控——( man 于英語(yǔ)中可單指'人“”或“男人”) 或許我應(yīng)說(shuō)，由人駕駛之太空旅航。
All of my life I have sought to understand the universe and find answers to these questions. I have been very lucky that my disability has not been a serious handicap. Indeed, it has probably given me more time than most people to pursue the quest for knowledge. The ultimate goal is a complete theory of the universe, and we are making good progress. Thank you for listening.
我一生都在探究想要了解宇宙并找出這些問(wèn)題之答案。我一直都非常幸運(yùn)，我的殘疾并沒(méi)造成嚴(yán)重障礙;說(shuō)真的，這反倒讓我比大部分人獲得更多時(shí)間以從事知識(shí)之追求。終極目標(biāo)是一套完備的宇宙論，而我們已有良好進(jìn)展。感謝您們的聆聽。
Chris Anderson: Professor, if you had to guess either way, do you now believe that it is more likely than not that we are alone in the Milky Way, as a civilization of our level of intelligence or higher? This answer took seven minutes, and really gave me an insight into the incredible act of generosity this whole talk was for TED.
安德森：教授，若您必須二選其一作猜測(cè)，此刻您是較相信還是較不相信我們是天河中唯一現(xiàn)水平或更高水平之智能文化?準(zhǔn)備這答案已花了7分多鐘，真讓我深切體會(huì)到這整個(gè)演講為TED所付出之，讓人難以置信之慷慨。
Stephen Hawking: I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves. The alternative is that civilizations don't last very long, but destroy themselves.
霍金：我想我們應(yīng)該是數(shù)百光年范圍內(nèi)之獨(dú)一文明;否則我們應(yīng)已收聽到電波。另一種可能是，該等文明都維持不久，就自我毀滅掉。
CA: Professor Hawking, thank you for that answer. We will take it as a salutary warning, I think, for the rest of our conference this week. Professor, we really thank you for the extraordinary effort you madeto share your questions with us today. Thank you very much indeed.
安德森： 霍金教授，謝謝您的解答。我想，我們會(huì)將之作為這一周余下會(huì)談之座右銘。教授，我們衷心感謝您今天為與我們分享您的問(wèn)題所作出之卓越貢獻(xiàn)。真的非常感謝您。
(Applause)
