BG: Okay, so we'll let you go and save it, and rescue it. | 布諾•吉商尼: 好吧 你快去維護並拯救它 | en-zh-tw |
Suzanne Lee. (SL: Thank you.) (Applause) | Suzanne Lee: >> Mulţumesc. (Aplauze) | en-ro |
The universe is really big. | Alam semesta benar-benar sangat besar. | en-id |
We live in a galaxy, the Milky Way Galaxy. | Mes gyvename galaktikoje - Paukščių Take. | en-lt |
There are about a hundred billion stars in the Milky Way Galaxy. | Υπάρχουν περίπου 100.000.000.000 άστρα στο γαλαξία Milky Way. | en-el |
And if you take a camera and you point it at a random part of the sky, and you just keep the shutter open, as long as your camera is attached to the Hubble Space Telescope, it will see something like this. | Dacă iei un aparat foto, îl îndrepţi într-un loc aleatoriu pe cer, şi ţii diafragma deschisă, cât timp camera e ataşată de Telescopul Spaţial Hubble, va vedea ceva de genul ăsta. | en-ro |
Every one of these little blobs is a galaxy roughly the size of our Milky Way -- a hundred billion stars in each of those blobs. | Svaka od tih malih mrlja je galaksija veličine slične našem Mlečnom putu - sto milijardi zvezda u svakoj od tih mrlja. | en-sr |
There are approximately a hundred billion galaxies in the observable universe. | Υπάρχουν περίπου 100.000.000.000 γαλαξίες στο παρατηρήσιμο σύμπαν. | en-el |
100 billion is the only number you need to know. | 100 miliardi è l'unico numero che vi basta sapere. | en-it |
The age of the universe, between now and the Big Bang, is a hundred billion in dog years. | Starost vesolja, med zdaj in Velikim Pokom je sto milijard v pasjih letih. | en-sl |
(Laughter) Which tells you something about our place in the universe. | (სიცილი) რომელიც გვეუბნება რაღაცას სამყაროში ჩვენი ადგილის შესახებ. | en-ka |
One thing you can do with a picture like this is simply admire it. | Jedino što možete sa ovom slikom jeste da joj se divite. | en-sr |
It's extremely beautiful. | Jako je lijepa. | en-hr |
I've often wondered, what is the evolutionary pressure that made our ancestors in the Veldt adapt and evolve to really enjoy pictures of galaxies when they didn't have any. | 銀河の写真などなかった頃に これを本当に楽しめるまで アフリカ南部の草原にいた私たちの祖先を順応させ 進化させた進化の要因は 何だろうとよく考えます | en-ja |
But we would also like to understand it. | My bychom jim však také chtěli porozumět. | en-cs |
As a cosmologist, I want to ask, why is the universe like this? | Với vai trò nhà vũ trụ học, tôi muốn hỏi: tại sao sao vũ trụ lại như thế này? | en-vi |
One big clue we have is that the universe is changing with time. | 一個線索就是宇宙是隨著時間而不斷變化的 | en-zh-tw |
If you looked at one of these galaxies and measured its velocity, it would be moving away from you. | Αν κοιτάζατε οποιονδήποτε από αυτούς τους γαλαξίες και μετρούσατε την ταχύτητά του, θα απομακρυνόταν από εσάς. | en-el |
And if you look at a galaxy even farther away, it would be moving away faster. | さらに遠い銀河を見ると もっと速く遠ざかっています | en-ja |
So we say the universe is expanding. | 所以我們說宇宙是在不斷膨脹的 | en-zh-tw |
What that means, of course, is that, in the past, things were closer together. | ما يعنيه ذلك، بالتأكيد، هو أنه في الماضي، كانت الأشياء أقرب لبعضها. | en-ar |
In the past, the universe was more dense, and it was also hotter. | Στο παρελθόν, το σύμπαν ήταν πιο πυκνό και ήταν επίσης πιο καυτό. | en-el |
If you squeeze things together, the temperature goes up. | ถ้าอัดอะไรเข้าด้วยกันแน่นๆ อุณหภูมิก็จะสูงขึ้นครับ | en-th |
That kind of makes sense to us. | Eso tiene sentido. | en-es |
The thing that doesn't make sense to us as much is that the universe, at early times, near the Big Bang, was also very, very smooth. | ის რასაც ასეთივე არსი არ გააჩნია არის ადრეული სამყარო, დიდ აფეთქებასთან ახლოს. ის იყო ასევე ძალიან, ძალიან გლუვი | en-ka |
You might think that that's not a surprise. | 여러분은 그게 그렇게 놀랍지 않다고 생각할지 모릅니다. | en-ko |
The air in this room is very smooth. | A levegő ebben a teremben nagyon sima. | en-hu |
You might say, "Well, maybe things just smoothed themselves out." | Lahko rečete: "No, morda se stvari same uredijo". | en-sl |
But the conditions near the Big Bang are very, very different than the conditions of the air in this room. | แต่ว่าสภาพใกล้ๆบิ๊กแบงมันต่างไปจาก สภาพอากาศในห้องนี้เยอะมากนะครับ | en-th |
In particular, things were a lot denser. | In particolare, le cose erano molto più dense. | en-it |
The gravitational pull of things was a lot stronger near the Big Bang. | 当时的地心引力 比现在强很多 | en-zh-cn |
What you have to think about is we have a universe with a hundred billion galaxies, a hundred billion stars each. | Wyobraźcie sobie - nasz wszechświat ma 100 miliardów galaktyk, i 100 miliardów gwiazd w każdej z nich. | en-pl |
At early times, those hundred billion galaxies were squeezed into a region about this big -- literally -- at early times. | A kezdeti időkben, az a 100 milliárd galaxis egy olyan kis térbe volt összepréselve, mint ez -- szó szerint, a kezdeti időkben. | en-hu |
And you have to imagine doing that squeezing without any imperfections, without any little spots where there were a few more atoms than somewhere else. | แล้วคุณก็ต้องคิดดูด้วยนะ ว่าการบีบอัด ที่ไร้ที่ติ ไม่มีแม้กระทั่งจุดเล็กจิ๋ว ที่มีอะตอมมากกว่าจุดอื่นสักแค่สองสามอะตอม ก็ไม่มี | en-th |
Because if there had been, they would have collapsed under the gravitational pull into a huge black hole. | وگرنه، تحت فشردگی گرانشی در یک سیاه چاله بزرگ فرو می ریزد. | en-fa |
Keeping the universe very, very smooth at early times is not easy; it's a delicate arrangement. | Mempertahankan kehalusan alam semesta muda tidaklah mudah, sebuah pengaturan yang sulit. | en-id |
It's a clue that the early universe is not chosen randomly. | Det är en ledtråd att det tidiga universum inte är ett slumpmässigt val. | en-sv |
There is something that made it that way. | Có điều gì đó đã khiến mọi sự theo hướng ấy. | en-vi |
We would like to know what. | Bizler bunun ne olduğunu anlamaya çalışıyoruz. | en-tr |
So part of our understanding of this was given to us by Ludwig Boltzmann, an Austrian physicist in the 19th century. | Parte do nosso entendimento nos foi dado por Ludwig Boltzmann, um físico austríaco, no século 19. | en-pt-br |
And Boltzmann's contribution was that he helped us understand entropy. | Dan Boltzmann membantu kita memahami entropi. | en-id |
You've heard of entropy. | 你们听见过熵 | en-zh-cn |
It's the randomness, the disorder, the chaoticness of some systems. | É o aleatório, a desordem, o caos de alguns sistemas. | en-pt-br |
Boltzmann gave us a formula -- engraved on his tombstone now -- that really quantifies what entropy is. | Boltzmann a fourni une formule -- aujourd'hui gravée sur sa tombe -- qui quantifie vraiment ce qu'est l'entropie. | en-fr |
And it's basically just saying that entropy is the number of ways we can rearrange the constituents of a system so that you don't notice, so that macroscopically it looks the same. | Về cơ bản mà nói entropy là số lượng các cách mà chúng ta có thể sắp xếp các hợp phần của hệ thống sao cho bạn không chú ý, sao cho nhìn bằng mắt thường nó không hề thay đổi. | en-vi |
If you have the air in this room, you don't notice each individual atom. | Na primer, vazduh u ovoj sobi, ne primetite njegov svaki pojedinačni atom. | en-sr |
A low entropy configuration is one in which there's only a few arrangements that look that way. | یک پیکربندی با آنتروپی پایین اونییه که تنها تعداد کمی حالت در اون به این صورت دیده میشه. | en-fa |
A high entropy arrangement is one that there are many arrangements that look that way. | Конфигурация с высокой энтропией – это та, где есть много вариантов расположения, которые выглядят таким образом. | en-ru |
This is a crucially important insight because it helps us explain the second law of thermodynamics -- the law that says that entropy increases in the universe, or in some isolated bit of the universe. | Questa teoria è assolutamente cruciale, perché ci aiuta a spiegare la seconda legge della Termodinamica -- la legge secondo cui l'entropia aumenta nell'universo, o in punti isolati dell'universo. | en-it |
The reason why entropy increases is simply because there are many more ways to be high entropy than to be low entropy. | 熵值增大的原因很简单 只因呈现出对应于大熵值的布局 比呈现出对应于小熵值的布局的方式多得多 | en-zh-cn |
That's a wonderful insight, but it leaves something out. | Esta é uma noção maravilhosa, mas deixa algo de fora. | en-pt-br |
This insight that entropy increases, by the way, is what's behind what we call the arrow of time, the difference between the past and the future. | Chápání rostoucí entropie stojí mimochodem za podstatou toho, co nazýváme časovou šipkou, rozdílem mezi minulostí a budoucností. | en-cs |
Every difference that there is between the past and the future is because entropy is increasing -- the fact that you can remember the past, but not the future. | Svaka promjena koja postoji između prošlosti i budućnosti jest uslijed povećanja entropije -- činjenica da se možemo sjetiti prošlosti, a ne budućnosti. | en-hr |
The fact that you are born, and then you live, and then you die, always in that order, that's because entropy is increasing. | 你出生 生活 然後死亡 這些事情都是依次發生的 原因都是熵值在不斷提高 | en-zh-tw |
Boltzmann explained that if you start with low entropy, it's very natural for it to increase because there's more ways to be high entropy. | Boltzmann vysvětlil, že když začnete u nízké entropie, je pro ni velmi přirozené, aby vzrůstala, protože existuje více způsobů, jak přejít k vysoké entropii. | en-cs |
What he didn't explain was why the entropy was ever low in the first place. | Was er nicht erklärte, war, warum die Entropie überhaupt jemals niedrig war. | en-de |
The fact that the entropy of the universe was low was a reflection of the fact that the early universe was very, very smooth. | To, że we wczesnym wszechświecie była ona niska odzwierciedla fakt że wczesny wszechświat był bardzo równomierny. | en-pl |
We'd like to understand that. | Chúng ta muốn hiểu điều đó. | en-vi |
That's our job as cosmologists. | זוהי עבודתנו בתור קוסמולוגים. | en-he |
Unfortunately, it's actually not a problem that we've been giving enough attention to. | Leider ist das kein Problem, dem wir bisher genug Aufmerksamkeit geschenkt haben. | en-de |
It's not one of the first things people would say, if you asked a modern cosmologist, "What are the problems we're trying to address?" | Není to jedna z prvních věcí, kterou by jmenoval, kdybyste se zeptali moderního kosmologa: "Jaké problémy se snažíme řešit?" | en-cs |
One of the people who did understand that this was a problem was Richard Feynman. | 認識到這個問題的人之一 便是理查德·費曼 | en-zh-tw |
50 years ago, he gave a series of a bunch of different lectures. | Hace 50 años que dio unas cuantas conferencias. | en-es |
He gave the popular lectures that became "The Character of Physical Law." | او سخنرانی های عمومی ایراد کرد به اسم "کاراکتر قانون فیزیکی". | en-fa |
He gave lectures to Caltech undergrads that became "The Feynman Lectures on Physics." | Ha tenuto lezioni per le matricole della Caltech che sono diventate "Le lezioni di Fisica di Feynman." | en-it |
He gave lectures to Caltech graduate students that became "The Feynman Lectures on Gravitation." | A oferit cursuri studenților doctoranzi de la Caltech care au devenit "Cursurile lui Feynman despre Gravitaţie." | en-ro |
In every one of these books, every one of these sets of lectures, he emphasized this puzzle: Why did the early universe have such a small entropy? | Dalam setiap buku ini, setiap rangkaian kuliah ini, dia menekankan teka-teki ini: Mengapa alam semesta awalnya memiliki entropi yang rendah? | en-id |
So he says -- I'm not going to do the accent -- he says, "For some reason, the universe, at one time, had a very low entropy for its energy content, and since then the entropy has increased. | 그는 말하기를 - 파인만의 액센트는 생략하지요 - "우주는 한때 총 에너지의 엔트로피가 낮았던 시절이 있었는데 그 이후로 엔트로피가 증가했다. | en-ko |
The arrow of time cannot be completely understood until the mystery of the beginnings of the history of the universe are reduced still further from speculation to understanding." | 宇宙の歴史の始まりの謎がさらに解かれて 臆測から理解となるまで この時間の方向性を完全に 理解することはできない」 | en-ja |
So that's our job. | Szóval ez a munkánk. | en-hu |
We want to know -- this is 50 years ago, "Surely," you're thinking, "we've figured it out by now." | Chcemy wiedzieć -- minęło już 50 lat, myślicie pewnie "Na pewno już to rozgryźliśmy." | en-pl |
It's not true that we've figured it out by now. | Не е вярно, че сме го разбрали до сега. | en-bg |
The reason the problem has gotten worse, rather than better, is because in 1998 we learned something crucial about the universe that we didn't know before. | Priežastis, kodėl problema pasidarė dar didesnė, o ne mažesnė, yra ta, kad 1998-aisiais mes apie visatą sužinojome kai ką labai svarbaus, ko anksčiau nežinojome. | en-lt |
We learned that it's accelerating. | ჩვენ გავიგეთ რომ ის აჩქარებით ფართოვდება. | en-ka |
The universe is not only expanding. | Universet udvider sig ikke kun. | en-da |
If you look at the galaxy, it's moving away. | Ако се вгледате в галактиката, тя се отдалечава. | en-bg |
If you come back a billion years later and look at it again, it will be moving away faster. | Eğer bir milyar yıl sonra gelir tekrar bakarsanız, daha da hızlı uzaklaştıklarını görürsünüz. | en-tr |
Individual galaxies are speeding away from us faster and faster so we say the universe is accelerating. | تک تک کهکشان ها سریعتر و سریعتر در حال دور شدن از ما هستند. بنابراین ما میگوییم که جهان داره شتاب می گیره. | en-fa |
Unlike the low entropy of the early universe, even though we don't know the answer for this, we at least have a good theory that can explain it, if that theory is right, and that's the theory of dark energy. | Evrenin başlangıcındaki düşük entropi sorunun aksine bu konuda tam bir yanıtımız olmasa da, onu açıklayacak iyi bir teorimiz var. Bu teori doğruysa elbet, teorinin adı Karanlık Enerji Teorisi. | en-tr |
It's just the idea that empty space itself has energy. | Je to len myšlienka toho, že samotný prázdny priestor má energiu. | en-sk |
In every little cubic centimeter of space, whether or not there's stuff, whether or not there's particles, matter, radiation or whatever, there's still energy, even in the space itself. | U svakom kubnom centrimetru svemira, bilo da ima nečega ili nema, bilo da ima čestica, materije, radijacije ili bilo čega, ipak ima energije, čak i u samom prostoru. | en-sr |
And this energy, according to Einstein, exerts a push on the universe. | Dan energi ini, menurut Einstein memberi dorongan pada alam semesta. | en-id |
It is a perpetual impulse that pushes galaxies apart from each other. | Galaksileri birbirinden uzaklaştıran, onları iten enerji de bu. | en-tr |
Because dark energy, unlike matter or radiation, does not dilute away as the universe expands. | אנרגיה שחורה, שלא כמו חומר או קרינה, אינה דועכת ככל שהיקום מתפשט. | en-he |
The amount of energy in each cubic centimeter remains the same, even as the universe gets bigger and bigger. | Cantitatea de energie în fiecare centrimetru cub rămâne constantă, chiar dacă universul devine din ce în ce mai mare. | en-ro |
This has crucial implications for what the universe is going to do in the future. | 이것은 우주의 미래에 대해 신중한 의미를 가지고 있는데 이에 따르는 | en-ko |
For one thing, the universe will expand forever. | Một điều là: vũ trụ sẽ phình mãi mãi. | en-vi |
Back when I was your age, we didn't know what the universe was going to do. | Ko sem bil vaše starosti, nismo vedeli, kaj se bo zgodilo z vesoljem. | en-sl |
Some people thought that the universe would recollapse in the future. | Algunos pensaban que en el futuro volvería a colapsar. | en-es |
Einstein was fond of this idea. | Einšteinas palaikė šią idėją. | en-lt |
But if there's dark energy, and the dark energy does not go away, the universe is just going to keep expanding forever and ever and ever. | Men finns det mörk energi och den inte försvinner så kommer universum att expandera för alltid. | en-sv |
14 billion years in the past, 100 billion dog years, but an infinite number of years into the future. | 14 mil millones de años en el pasado, 100 mil millones de años caninos, una cantidad infinita de años hacia el futuro. | en-es |
Meanwhile, for all intents and purposes, space looks finite to us. | 在此期间 不论我们有什么意图或目的 宇宙空间在我们看来都是有限的 | en-zh-cn |
Space may be finite or infinite, but because the universe is accelerating, there are parts of it we cannot see and never will see. | O espaço pode ser finito ou infinito, mas porque o universo está acelerando, há partes que não podemos ver e nunca veremos. | en-pt-br |
There's a finite region of space that we have access to, surrounded by a horizon. | Bizim evrende uaşabileceğimiz alan sınırlı, hatta bir ufukla sınırlı. | en-tr |
So even though time goes on forever, space is limited to us. | Então mesmo que o tempo continue para sempre, espaço é limitado para nós. | en-pt-br |
Finally, empty space has a temperature. | În final, spaţiul gol are o temperatură. | en-ro |
In the 1970s, Stephen Hawking told us that a black hole, even though you think it's black, it actually emits radiation when you take into account quantum mechanics. | No anos 1970, Stephen Hawking disse-nos que um buraco negro, mesmo que pensem que é negro, na verdade emite radiação, quando se tem em conta a mecânica quântica. | en-pt |
The curvature of space-time around the black hole brings to life the quantum mechanical fluctuation, and the black hole radiates. | Lengkungan dari ruang-waktu di sekitar lubang hitam memunculkan gejolak kuantum mekanik dan lubang hitam memancarkannya. | en-id |
A precisely similar calculation by Hawking and Gary Gibbons showed that if you have dark energy in empty space, then the whole universe radiates. | ฮอว์กิ้ง และ แกรี่ กิบบอนส์ (Gary Gibbons) ได้ทำการคำนวณออกมาได้ผลคล้ายๆกันครับ ซึ่งแสดงว่า มีพลังงานมืดอยู่ในพื้นที่ว่างเปล่าของอวกาศ และเอกภพก็ฉายรังสีออกมาโดยทั่ว | en-th |
