Kurzgesagt (In a Nutshell), The Fermi Paradox — Where Are All The Aliens? (1/2)

The Fermi Paradox — Where Are All The Aliens? (1/2)

Are we the only living things in the entire universe?

The observable universe is about 90 billion light years in diameter.

There are at least one hundred billion galaxies, each with one hundred to one thousand billion stars.

Recently, we've learned that planets are very common too.

And, there are probably trillions and trillions of habitable planets in the universe.

Which means, there should be lots of opportunity for life to develop and exist, right?

But where is it?

Shouldn't the universe be teeming with spaceships?

Let's take a step back.

Even if there are alien civilizations in other galaxies,

There's no way we'll ever know about them.

Basically, everything outside of our direct galactic neighborhood,

the so called "Local Group", is pretty much out of our reach forever,

because of the expansion of the universe.

Even if we had really fast spaceships,

it would literally take billions of years to reach these places,

traveling through the emptiest areas in the universe.

So, let's focus on the Milky Way.

The Milky Way is our home galaxy.

It consists of up to four hundred billion stars.

That's a lot of stars, roughly ten thousand for every grain of sand on earth.

There are about twenty billion sunlike stars in the Milky Way,

and estimates suggest that a fifth of them, have an earth sized planet in it's habitable zone,

the area with conditions that enable life to exist.

If only 0.1% of those planets harbored life, there would be one million planets with life in the milky way.

But wait, there's more.

The Milky Way is about thirteen billion years old. In the beginning, it would not have been a good place for life,

because things exploded a lot. But after one to two billion years, the first habitable planet was born.

Earth is only four billions years old, so there have probably been trillions of chances for life to develop on other planets in the past.

If only a single one of them had developed into a space traveling super civilization, we would have noticed by now.

What would such a civilization look like?

There are three categories.

A type one civilization would be able to access the whole energy available on its planet.

In case you are wondering, we are currently around zero point seven three on the scale,

and we should reach type one sometime in the next couple hundred years.

Type two would be a civilization capable of harnessing all of the energy of its home star.

This would require some serious science fiction, but it is doable in principle.

Concepts like the Dyson Sphere, a giant complex surrounding the sun, would be conceivable.

Type three is a civilization that basically controls it's whole galaxy and its energy

An alien race this advanced would probably be godlike to us.

But why should we be able to see such an alien civilization in the first place?

If we were to build generation spaceships that could sustain a population for around one-thousand years,

we could colonize the whole galaxy in two million years.

Sounds like a long time, but remember, the milky way is huge.

So, if it takes a couple of million years to colonize the entire galaxy,

and there are possibly millions, if not billions of planets that sustain life in the Milky Way,

and these other life forms have had considerably more time than we've had, then...

Where are all the aliens?

This, is the Fermi Paradox, and nobody has an answer to it.

But we do have some ideas.

Let's talk about filters.

A filter in this context represents a barrier that is really hard for life to overcome.

They come in various degrees of scary.

One: There are Great Filters and we've passed them.

Maybe it is way harder for complex life to develop then we think.

The process, allowing life to begin, hasn't yet been completely figured out,

and the conditions required may be really complicated.

Maybe in the past, the Universe was way more hostile, and only recently things have cooled down to make complex life possible.

This would also mean that we may be unique, or at least one of the first, if not the first civilization in the entire Universe.

Two: There are Great Filters and they are ahead of us.

This one, would be really really bad.

Maybe life on our level exists everywhere in the Universe but it gets destroyed when it reaches a certain point, a point that lies ahead of us.

For example, awesome future technology exists, but when activated, it destroys the planet.

The last words of every advanced civilization would be:

"This new device will solve all of our problems, once I push this button!"

If this is true, then we are closer to the end then the beginning of human existence.

Or, maybe there is an ancient type three civilization, that monitors the universe,

and once a civilization is advanced enough, it gets eliminated, in an instant.

Maybe there is something out there, that it would be better not to discover.

There is no way for us to know.

One final thought: maybe we are alone.

Right now, we have no evidence that there's any life besides us.

Nothing. The Universe appears to be empty and dead.

No ones sending us messages, no one answering our calls.

We may be completely alone, trapped on a tiny moist mud ball in an eternal Universe.

Does that thought scare you? If it does, you are having the correct emotional reaction.

If we let life on this planet die, perhaps there would be no life left in the Universe. Life would be gone, maybe forever.

If this is the case, we just have to venture to the stars and become the first Type Three civilization,

To keep the delicate flame of life existing, and to spread it until the universe breathes its final breath,

and vanishes into oblivion.

The universe is too beautiful not to be experienced by someone.

So, let's focus on the Milky Way. 所以,让我们专注于银河系。

The Milky Way is our home galaxy. A Via Láctea é a nossa galáxia natal.

It consists of up to four hundred billion stars. وتتكون من ما يصل إلى أربعمائة مليار نجم. Consiste em até quatrocentos bilhões de estrelas.

But wait, there's more. でも、待ってください、さらにあります。

The Milky Way is about thirteen billion years old. In the beginning, it would not have been a good place for life, يبلغ عمر مجرة درب التبانة حوالي ثلاثة عشر مليار سنة. في البداية، لم يكن مكانًا جيدًا للحياة، La Voie lactée a environ treize milliards d'années. Au début, elle n'aurait pas été un endroit propice à la vie, 銀河系は約130億年の歴史があります。最初の頃は、生命にとって良い場所ではなかったでしょう。 银河系大约有 130 亿年的历史。一开始,它不会是一个适合生活的地方,

because things exploded a lot. But after one to two billion years, the first habitable planet was born. denn es gab viele Explosionen. Aber nach ein bis zwei Milliarden Jahren wurde der erste bewohnbare Planet geboren. porque as coisas explodiram muito. Mas depois de um a dois bilhões de anos, nasceu o primeiro planeta habitável.

Earth is only four billions years old, so there have probably been trillions of chances for life to develop on other planets in the past. ||||十億||||||||兆|||||||||||| 地球只有四十亿年的历史,因此过去可能有数万亿次生命在其他星球上发展的机会。

If only a single one of them had developed into a space traveling super civilization, we would have noticed by now. ||||||||||||||||||bemerkt|| لو أن واحدًا منهم فقط قد تطور إلى حضارة خارقة تسافر عبر الفضاء، لكنا قد لاحظنا ذلك الآن. Hätte sich nur ein einziger von ihnen zu einer raumfahrenden Superzivilisation entwickelt, hätten wir das schon längst bemerkt. Si una sola de ellas se hubiera convertido en una supercivilización que viajara por el espacio, ya nos habríamos dado cuenta. Si un seul d'entre eux s'était transformé en une super civilisation voyageant dans l'espace, nous l'aurions déjà remarqué. もし彼らの中で一つだけでも宇宙旅行をする超文明に発展していたら、今頃は気づいていたでしょう。 Se apenas um deles tivesse se desenvolvido em uma supercivilização espacial, já teríamos notado. 如果他们中只有一个人发展成为太空旅行的超级文明,我们现在已经注意到了。

What would such a civilization look like? ¿Cómo sería una civilización así? そのような文明はどのようなものなのでしょうか? Como seria tal civilização?

There are three categories. 三つのカテゴリがあります。

A type one civilization would be able to access the whole energy available on its planet. Una civilización de tipo uno sería capaz de acceder a toda la energía disponible en su planeta. Une civilisation de type 1 serait capable d'accéder à toute l'énergie disponible sur sa planète. Цивилизация первого типа сможет получить доступ ко всей энергии, доступной на ее планете. 第一类文明将能够获取其星球上可用的全部能量。

In case you are wondering, we are currently around zero point seven three on the scale, Falls Sie sich wundern, wir stehen derzeit bei null Komma sieben drei auf der Skala, En caso de que se lo pregunte, actualmente estamos en torno al cero coma siete tres en la escala, Au cas où vous vous poseriez la question, nous nous situons actuellement à zéro virgule sept trois sur l'échelle, Caso você esteja se perguntando, estamos atualmente em torno de zero vírgula sete três na escala, Если вам интересно, в настоящее время мы находимся около нуля целых семь десятых десятых долей шкалы, 如果您想知道,我们目前的规模大约为零点七三,

and we should reach type one sometime in the next couple hundred years. ||||||irgendwann|||||| y deberíamos alcanzar el tipo uno en algún momento de los próximos doscientos años. e devemos alcançar o tipo um em algum momento nos próximos duzentos anos. 我们应该在未来几百年的某个时候达到类型一。

Type two would be a civilization capable of harnessing all of the energy of its home star. ||||||||exploiter|||||||| ||||||||nutzen|||||||| ||||||||利用する|||||||| النوع الثاني سيكون حضارة قادرة على تسخير كل طاقة نجمها الأصلي. El tipo dos sería una civilización capaz de aprovechar toda la energía de su estrella natal. Le deuxième type serait une civilisation capable d'exploiter toute l'énergie de son étoile d'origine. O tipo dois seria uma civilização capaz de aproveitar toda a energia de sua estrela natal. 第二类将是一个能够利用其母星所有能量的文明。

This would require some serious science fiction, but it is doable in principle. ||||||||||faisable|| ||||||||||machbar|| ||||||||||実行可能|| Cela nécessiterait un peu de science-fiction, mais c'est en principe faisable. Isso exigiria alguma ficção científica séria, mas é factível em princípio. Для этого потребуется серьезная научная фантастика, но в принципе это выполнимо. 这需要一些严肃的科幻小说,但原则上是可行的。

Conceitos como a Esfera Dyson, um complexo gigante em torno do sol, seriam concebíveis. 像戴森球这样的概念,一个围绕太阳的巨大复合体,是可以想象的。

Una raza alienígena tan avanzada probablemente sería divina para nosotros.

Столь развитая инопланетная раса, вероятно, была бы для нас богоподобной. 这种先进的外星种族对我们来说可能是神一样的。

But why should we be able to see such an alien civilization in the first place? |||||||||||||das|| Aber warum sollten wir überhaupt in der Lage sein, eine solche außerirdische Zivilisation zu sehen? Pero, ¿para qué íbamos a poder ver una civilización tan extraterrestre? Mais pourquoi devrions-nous être en mesure de voir une telle civilisation extraterrestre ? しかし、そもそもなぜ私たちがそのような異星文明を見ることができるのでしょうか? Mas por que deveríamos ser capazes de ver uma civilização tão alienígena em primeiro lugar?

If we were to build generation spaceships that could sustain a population for around one-thousand years, |||||||||soutenir||||||| |||||||||aufrechterhalten||||||| إذا أردنا أن نبني سفن فضاء جيلية يمكنها الحفاظ على سكان لحوالي ألف عام، Si construyéramos naves espaciales generacionales que pudieran mantener una población durante unos mil años, Si nous construisions des vaisseaux spatiaux de nouvelle génération capables d'accueillir une population pendant environ mille ans, もし私たちが千年ほどの間、人口を維持できる世代宇宙船を建造することができたとしたら、 Se construíssemos naves espaciais de geração que pudessem sustentar uma população por cerca de mil anos, 如果我们要建造可以维持人口大约一千年的世代宇宙飞船,

we could colonize the whole galaxy in two million years. ||kolonisieren||||||| ||sömürmek||||||| ||植民地化する||||||| 我们可以在两百万年内殖民整个银河系。

Sounds like a long time, but remember, the milky way is huge. Похоже, давно, но помните, Млечный путь огромен.

So, if it takes a couple of million years to colonize the entire galaxy, 所以,如果殖民整个银河系需要几百万年,

and there are possibly millions, if not billions of planets that sustain life in the Milky Way, et il y a peut-être des millions, voire des milliards de planètes qui abritent la vie dans la Voie lactée, 银河系中可能有数百万甚至数十亿的行星维持生命,

and these other life forms have had considerably more time than we've had, then... |||||||deutlich mehr|||||| |||||||かなり|||||| そして、これらの他の生命体は私たちが持っているよりもかなり多くの時間を持っていたなら... 而这些其他生命形式比我们拥有的时间要多得多,那么……

Where are all the aliens? 全てのエイリアンはどこにいるのか? 所有的外星人都在哪里?

This, is the Fermi Paradox, and nobody has an answer to it. これがフェルミの逆説であり、誰もその答えを持っていない。 Это парадокс Ферми, и ни у кого нет ответа. 这就是费米悖论,没有人能回答。

But we do have some ideas. Pero tenemos algunas ideas. しかし、私たちはいくつかのアイデアを持っています。

Let's talk about filters. |||Filter Hablemos de filtros.

A filter in this context represents a barrier that is really hard for life to overcome. |||||||||||||||يتجاوز يمثل المرشح في هذا السياق حاجزًا يصعب على الحياة التغلب عليه. Dans ce contexte, un filtre représente un obstacle que la vie a beaucoup de mal à franchir. Um filtro neste contexto representa uma barreira muito difícil de ser superada pela vida. 在这种情况下,过滤器代表了生命真正难以克服的障碍。

They come in various degrees of scary. ||||||gruselig ||||درجات|| أنها تأتي بدرجات مختلفة من مخيف. Los hay de varios grados de miedo. Eles vêm em vários graus de assustador. 他们有不同程度的可怕。

One: There are Great Filters and we've passed them. ||||||wir haben|| Erstens: Es gibt große Filter, und wir haben sie überwunden. Uno: Hay Grandes Filtros y los hemos pasado. Premièrement : il existe de grands filtres et nous les avons dépassés. Um: Existem Grandes Filtros e nós passamos por eles. Первый: есть отличные фильтры, и мы их прошли. 一:有很棒的过滤器,我们已经通过了它们。

Maybe it is way harder for complex life to develop then we think. Tal vez sea mucho más difícil que se desarrolle vida compleja de lo que pensamos. Il est peut-être beaucoup plus difficile de développer une vie complexe que nous ne le pensons. 也许复杂的生命比我们想象的更难发展。

The process, allowing life to begin, hasn't yet been completely figured out, ||erlaubend||||||||| |||||başlamak|||||| Der Prozess, der die Entstehung von Leben ermöglicht, ist noch nicht vollständig erforscht, El proceso que permite que comience la vida aún no se ha descifrado por completo, Le processus qui permet à la vie de commencer n'a pas encore été complètement élucidé, Процесс, позволяющий зародиться жизни, еще полностью не выяснен, 这个过程,让生命开始,还没有完全弄清楚,

and the conditions required may be really complicated. und die erforderlichen Bedingungen können sehr kompliziert sein. 而且所需的条件可能真的很复杂。

Maybe in the past, the Universe was way more hostile, and only recently things have cooled down to make complex life possible. |||||||||feindlich||||||abgekühlt|||||| |||||||||||||||soğudu|||||| |||||||||||||||冷却された|||||| ربما كان الكون في الماضي أكثر عدائية، ولم تهدأ الأمور إلا مؤخرًا لجعل الحياة المعقدة ممكنة. Vielleicht war das Universum in der Vergangenheit viel lebensfeindlicher, und erst in jüngster Zeit haben sich die Dinge abgekühlt, so dass komplexes Leben möglich wurde. Talvez no passado, o Universo fosse muito mais hostil, e só recentemente as coisas esfriaram para tornar a vida complexa possível. Возможно, в прошлом Вселенная была более враждебной, и только недавно все остыло, чтобы сделать возможной сложную жизнь. 也许在过去,宇宙更加敌对,直到最近事情才冷却下来,使复杂的生命成为可能。

This would also mean that we may be unique, or at least one of the first, if not the first civilization in the entire Universe. 这也意味着我们可能是独一无二的,或者至少是第一个,如果不是整个宇宙中的第一个文明。

Two: There are Great Filters and they are ahead of us. ثانيًا: هناك مرشحات رائعة وهي أمامنا. Zweitens: Es gibt große Filter, und sie sind uns voraus. Dos: Hay Grandes Filtros y van por delante de nosotros. Dois: Existem Grandes Filtros e eles estão à nossa frente. Второй: есть отличные фильтры, и они впереди нас. 二:有很棒的过滤器,它们在我们前面。

This one, would be really really bad. 这一个,真的很糟糕。

Maybe life on our level exists everywhere in the Universe but it gets destroyed when it reaches a certain point, a point that lies ahead of us. |||||||||||||||||||||||liegt||| ||||||||||||||||||||أداة تعريف|||تكمن||| ||||||||||||||ne zaman|||||||||||| ربما الحياة على مستوانا موجودة في كل مكان في الكون، لكنها تتدمر عندما تصل إلى نقطة معينة، نقطة تقع أمامنا. Tal vez la vida a nuestro nivel exista en todas partes del Universo, pero se destruye cuando llega a cierto punto, un punto que está por delante de nosotros. もしかしたら、私たちのレベルの生命は宇宙のどこにでも存在するが、ある一定のポイントに達したときに破壊されるのかもしれない。それは私たちの前にあるポイントだ。 Talvez a vida no nosso nível exista em todo o Universo, mas é destruída quando chega a um certo ponto, um ponto que está à nossa frente. Возможно, жизнь на нашем уровне существует повсюду во Вселенной, но она разрушается, когда достигает определенной точки, точки, которая находится впереди нас. 也许我们这个层次的生命存在于宇宙中的任何地方,但是当它到达某个点时,它就会被摧毁,这个点就在我们面前。

For example, awesome future technology exists, but when activated, it destroys the planet. Par exemple, une technologie future géniale existe, mais lorsqu'elle est activée, elle détruit la planète. 例えば、素晴らしい未来の技術は存在するが、それを起動すると惑星を破壊する。 Por exemplo, existe uma incrível tecnologia futura, mas quando ativada, destrói o planeta. 例如,存在令人敬畏的未来技术,但一旦被激活,它就会摧毁地球。

The last words of every advanced civilization would be: すべての高度な文明の最後の言葉はこうである: 每一个先进文明的遗言都是:

"This new device will solve all of our problems, once I push this button!" ||Gerät|||||||sobald|||| "Ce nouvel appareil résoudra tous nos problèmes, une fois que j'aurai appuyé sur ce bouton ! “这个新设备将解决我们所有的问题,只要我按下这个按钮!”

If this is true, then we are closer to the end then the beginning of human existence. Wenn das stimmt, dann sind wir näher am Ende als am Anfang der menschlichen Existenz. Se isso for verdade, então estamos mais perto do fim do que do começo da existência humana.

Or, maybe there is an ancient type three civilization, that monitors the universe, ||||||||||izler|| Ou, talvez haja uma antiga civilização tipo três, que monitora o universo, Или, может быть, существует древняя цивилизация третьего типа, которая следит за вселенной,

and once a civilization is advanced enough, it gets eliminated, in an instant. |||||||||消滅する||| Und sobald eine Zivilisation weit genug fortgeschritten ist, wird sie im Handumdrehen eliminiert. et une fois qu'une civilisation est suffisamment avancée, elle est éliminée en un instant. e uma vez que uma civilização é avançada o suficiente, ela é eliminada, em um instante. и как только цивилизация становится достаточно развитой, она мгновенно уничтожается. 一旦一个文明足够先进,它就会在瞬间被淘汰。

Maybe there is something out there, that it would be better not to discover. ربما هناك شيء ما، ومن الأفضل عدم اكتشافه. Il existe peut-être quelque chose qu'il vaut mieux ne pas découvrir. 外に何かあるかもしれない、それを発見しない方がいいかもしれない。 也许那里有一些东西,最好不要发现。

There is no way for us to know. Nous n'avons aucun moyen de le savoir. 私たちには知るすべがありません。

One final thought: maybe we are alone. 最後の考え: もしかすると私たちは一人なのかもしれない。 最后一个想法:也许我们是孤独的。

Right now, we have no evidence that there's any life besides us. No momento, não temos evidências de que haja vida além de nós. 目前,我们没有证据表明除了我们之外还有其他生命。

Nothing. The Universe appears to be empty and dead.

No ones sending us messages, no one answering our calls.

We may be completely alone, trapped on a tiny moist mud ball in an eternal Universe. |||||||||humide|boue||||| |||||||||رطب|||||| |||||||||nemli|||||| |||||||||湿った|||||| |||||||||feucht|||||| Podemos estar completamente sozinhos, presos em uma pequena bola de lama úmida em um Universo eterno. Мы можем быть совершенно одни, пойманные на крошечный влажный комочек грязи в вечной Вселенной. 我们可能完全孤独,被困在永恒宇宙中一个微小的潮湿泥球中。

Does that thought scare you? If it does, you are having the correct emotional reaction. |||ängstigen||||||||||emotional| |||怖がらせる||||||||||| Erschreckt Sie dieser Gedanke? Wenn ja, dann haben Sie die richtige emotionale Reaktion. ¿Le asusta ese pensamiento? Si es así, tu reacción emocional es la correcta. Эта мысль вас пугает? Если это так, у вас правильная эмоциональная реакция.

If we let life on this planet die, perhaps there would be no life left in the Universe. Life would be gone, maybe forever. Si dejáramos morir la vida en este planeta, quizá no quedaría vida en el Universo. La vida desaparecería, quizá para siempre. Если мы позволим жизни на этой планете умереть, возможно, во Вселенной не останется жизни. Жизнь ушла бы, может быть, навсегда.

If this is the case, we just have to venture to the stars and become the first Type Three civilization, |||||||||nous aventurer|||||||||| Wenn das der Fall ist, müssen wir nur zu den Sternen aufbrechen und die erste Zivilisation vom Typ Drei werden, Se for esse o caso, temos apenas que nos aventurar nas estrelas e nos tornar a primeira civilização do Tipo Três, 如果是这样,我们只需要冒险去星际,成为第一个三类文明,

To keep the delicate flame of life existing, and to spread it until the universe breathes its final breath, |||zarte|Flamme|||||||||||||| |||||||var olan||||||||nefes alır||| ||||炎|||||||||||||| Um die zarte Flamme des Lebens am Leben zu erhalten und sie zu verbreiten, bis das Universum seinen letzten Atemzug getan hat, Maintenir la délicate flamme de la vie et la répandre jusqu'à ce que l'univers rende son dernier souffle, 生命の繊細な炎を存在させ、宇宙が最後の息を吐くまでそれを広げるために、 Para manter a delicada chama da vida existindo e espalhá-la até que o universo dê seu último suspiro, Чтобы тонкое пламя жизни сохранялось и распространялось до тех пор, пока вселенная не испустит свой последний вздох, 为了保持生命的微妙火焰存在,并将其传播到宇宙呼吸最后一口气,

and vanishes into oblivion. |||l'oubli |verschwindet||Vergessenheit |yok olur||unutulmuşluğa |消える|| そして忘却へと消え去る。 e desaparece no esquecimento. 并消失在遗忘之中。
