Во вступительной речи от 11 мая 1996 Карл Саган поделился своими мыслями о значении этой фотографии:
"Взгляните ещё раз на эту точку. Это здесь. Это наш дом. Это мы. Все, кого вы любите, все, кого вы знаете, все, о ком вы когда-либо слышали, каждый когда-либо существовавший человек прожил свою жизнь на ней. Все наши радости и страдания, тысячи самоуверенных религий, идеологий и экономических доктрин, каждый охотник и собиратель, каждый герой и трус, каждый созидатель и разрушитель цивилизаций, каждый король и крестьянин, каждая влюблённая юная пара, каждая мать и каждый отец, каждый подающий надежды ребёнок, каждый изобретатель и путешественник, каждый духовный учитель, каждый продажный политик, каждая «суперзвезда», каждый «верховный лидер», каждый святой и грешник в истории нашего вида жили здесь — на этой пылинке, зависшей в лучах солнечного света.
Земля — очень маленькая сцена на необъятной космической арене. Вспомните о реках крови, пролитых всеми полководцами и императорами, чтобы, в лучах славы и триумфа, ненадолго стать хозяевами части этой песчинки. Вспомните о бесконечных жестокостях, совершаемых обитателями одного уголка этой точки над едва отличимыми от них обитателями другого уголка. О том, как часты их разногласия, о том, как жаждут они убивать друг друга, о том, как горяча их ненависть.
Наши позёрства, наша воображаемая значимость, иллюзия о нашем привилегированном положении во вселенной пасуют перед этой точкой бледного света. Наша планета — одинокая крупинка в огромной окружающей космической тьме. В нашей безвестности, во всей этой бесконечности, нет и намёка на то, что помощь придёт откуда-то извне, чтобы спасти нас от самих себя.
Земля пока — единственный известный мир, ютящий жизнь. Нашему виду больше некуда переселяться — по крайней мере, в ближайшем будущем. Побывать — да. Поселиться — ещё нет. Нравится вам это или нет, на данный момент Земля — наш дом.
Кто-то сказал, что астрономия прививает смирение и воспитывает характер. Наверное, нет лучшего доказательства глупости человеческого тщеславия, чем этот далёкий образ нашего крошечного мира. Для меня, он подчёркивает нашу обязанность быть добрее друг с другом, беречь и лелеять бледно-голубую точку — единственный дом, который мы когда-либо знали."
**This is the text from Pale Blue Dot in Russian, in case you want to follow along and study.
Yeah... it's time to start working on terraforming the other celestial bodies around us. Viva to the extreme techno-gaianism!! :)
Ah but as Carl Sagan said "Побывать — да. Поселиться — ещё нет."Quote:

However, when using that very same approach to heat up Mars or cool down Venus, we can monitor the situation and correct it as needed. However, as Carl Sagan noted at some point in time, if I remember him correctly, we cannot embark on that task until we cannot confirm 100% there's no life on those planets. Because, if there is life, even the microbial life, we will be destroying it by introducing our terrestrial microbial life. And that means that if the humanity thinks its moral to do that, the extra-terrestrial life who wants to do that with the Earth will find it legitimate too. With the very sad consequences for the terrestrial life since our planet is very vulnerable from the attack (the impact or mass-microbial infestation) from the outer space. So, until we can find the proper definitions for life and confirm there's no life on those planets, we can't start it unfortunately. But, technically, that is possible with today's tools and the demand is there - since the stable Mars habitation is the key to the riches of the asteroid belt. So, the market is there and the ability is there, it's just the moral issues we have to settle down first. ;)
Yeah, the moral issues are what concern me the most. Life can abound in forms we may not even be aware of as humans, since our senses are limited only to a certain spectrum which we evolved to sense our world. Our senses have not evolved to see certain colors or shapes which may be quite clear to a butterfly, for example. How would we even know if we were destroying an entire race of beings? Definitely more study and testing is needed. And Space can never be the province of any one country. Newt Gingrich's recent comments about building a moon colony would be laudable, except for his rhetorical insistence that it must be an AMERICAN lunar colony. No one can lay claim to the moon! Or any other planet for that matter. Humans will need to work together, in international cooperation, to properly explore the "final frontier." But it will be a long time before we can manage this, I think. Maybe not even in my lifetime or yours. We can barely tolerate the differences in our skin color and language and culture - how could we even begin to contemplate relating to a completely alien, extraterrestrial, species?
Let's be realistic. The whole "international" thing will never work out. The most "international" we can probably make out of it would be an international corporation with the countries having certain share. As for the Moon, the battle for the base and mining of the He-3 had already begun long ago. Now you see countries like India which not only announce their space program, but have practically launched the unmanned lunar probe which actually reached to the Moon and have done its job. So, do you think India has nothing else to do, but try fancy expensive space programs for fun? There's no poverty in India anymore? No expensive military programs to match Pakistan? They simply had no choice - if they let the Moon be conquered by the other countries, they will never get to the source of He-3 and will be obliged to purchase electricity from the other countries in the next half century.Quote:

Rare minerals, uranium, hydrogen for fuel and energy, etc. Who do you think will get to Mars first, the US or India?
By the way, there's nothing fundamentally wrong with a country claiming a newly discovered territory. Nothing I can think of that would be prohibited by the international law.
Ah, it's all relative. Also, how close can the contact with the possible extraterrestrial species could be? It could be as close to nothing as today even if we know they are there. And there's great potential for a war since historically that was the only way to settle disputes between the various kind of species at least on our planet. Would you care to kill a wolf? Would a wolf care to kill you? And both you and wolf are mammals. Would anything change if you meet aQuote:

Let's be realistic. The whole "international" thing will never work out.
If all of these nations could, you know, work together, the issue of "who gets there first" would be irrelevant and resources could be evenly distributed. But I am realistic and I realize that is unlikely to happen. Humans are basically going to fight for every inch, instead of cooperate and logically and fairly divvy things up which would seem more rational. But humans are not very rational, are they? Yes, Helium will be in big demand shortly, because we need it to run MRI's and other life-saving technology, and Helium supplies on earth are almost exhausted.
America is not really in the "Space Race" like it used to be. NASA has been stripped to bare-bones and the shuttles have been retired. Private Enterprise wants to set up hotels orbiting earth to make money from the ultra rich, who are the only ones who will be able to afford to stay there.
War is the way life on earth settles things. How do we know anything about extraterrestrial concepts...? They may not need to have a "war." They may not even recognize us as sentient beings and it could be like "The Hitchhiker's Guide to the Galaxy" and they could just blast earth to put in a new highway. Who knows....? No one does.
Anyway, this is an interesting conversation but if you are going to condescend to me, why should I continue to discuss it with you?
I apologize if I had hurt you, that was not my intention. Usually, I'm pretty sarcastic when expressing my opinions, so I would appreciate if you could cut me some slack on that. This conversation is interesting for me too. Actually, I'm so interested in the topic that some time back I used to dig into the exobiology and exopsychology to get some better understanding of the topic.Quote:

Therefore, I think this topic is important and it also helps us to better understand ourselves. Regardless of the outcome, it's like learning the foreign language - you may not learn it properly, but in the end you understand your own language better.
So, let's discuss the "war" issue. You see, the evolution of bodies goes from the more primitive building blocks to the more complex in the way that the more complex are built up of the primitive blocks and combined in a certain way. That leads to the more complex organisms CONSUMING the bodies of the other organisms to extract the primitive building blocks in order to sustain their complex bodies in the most economical way. So, the sheep would not hunt the bunnies, but it would still consume the grass. So, when we're talking about the sentient extraterrestrial beings, we should realize the great chance of those beings consuming some other beings on their native planet thus being intimately familiar with the destruction of the foreign life in support of their own life. Which is a solid foundation for war. There should be something stopping those beings from war, otherwise the war would occur naturally. And the hostile environment may help (I mean our Earth environment may be hostile towards the extraterrestrials), but it might also not stop the war either, because those beings might want to "Exoform" our Earth the same way we want to "Terraform" other planets.
I agree to a certain extent, however, let's think about it another way. Using the existing technology, it might take up to several hundred years before Mars could be inhabited by humans wearing no physiological protection. The longest processes are heating Mars and beefing up its atmosphere. Why not to start now? It will create the expectations, the market, the investments, the emerge of new technology, etc. Lots of benefits, what do you think?Quote:

Oh that is very true! But learning Russian really messes with my head. When I speak Russian for extended periods, like I did when I lived in Russia, my English grammar gets messed up and I start speaking English "wrong." Does that happen to you?Quote:

I am not so convinced that the aggressive political forms always win. It seems to me that the "war" between aggression and cooperation never ends, but continues, round after round, into infinity. Conservatives versus liberals, etc. Cooperation is just as inherent in our gene pool as aggression. After all, we had to help each other to survive at the dawn of humanity and the same is true today. When times get tough, people come together and help each other. It might take a threat from an alien force to unite humankind completely. But in the meantime, I still believe in the power of cooperation, and love, to be greater than aggression, hate and destruction. Maybe you would think I am naive, and maybe I am, but I will never agree that aggression and killing is superior to cooperation and caring for each other.Quote:

Sure, there are abundant ways in which the Helium-3 would help us. I favor establishing an international moon colony where the stuff can be extracted. But we will see how "international" it is in time... It would seem to me that the brightest scientists on the planet would prefer, if possible, to work together for the greater good and combine their wealth of knowledge, rather than be pitted together by governments intent on destroying each other. But that has always been the feeling of scientists and more intelligent people. Unfortunately, the most intelligent people are rarely the ones who lead us. Instead, it seems that the aggressive, power-hungry types of people are the ones who rise to leadership, and then try to pretend they are Alexander the Great and conquer the world under the guise of some "preferred" system of government - be it democracy, communism or god knows what else.Quote:

Perhaps. I don't mind space hotels. But I think there ought to be a way for the "99%" to benefit from such an experience, and not solely the uber-wealthy.Quote:

I think if you behave like a domestic dog, that might give a wrong impression of the humanity either. And if you start singing some of Celine Dione songs, the extraterrestrial might feel like a good opportunity to dive into the north Atlantic to fetch some extra precious stones. :) Off the top of my head, you need to stay still, not run or hide, and not smile, but slowly wave your straight hands palms forward until the other being would do something. Then, you slowly try to imitate what it did until it tries to imitate what you do. If you get to the point the being is trying to imitate you, you've got 90% of the success in the first contact because the being is considerate of you and recognizes you're sentient. The rest depends on what happens next, which is up to you at that point. And what happens if you don't get that 90%? That's why you need to get yourself familiar with at least some concepts of the exopsychology. :)Quote:

Ah, but if this alien being has no limbs - and thus no concept of limbs - how would such a gesture be interpreted? The alien is not going to "grok"* the human-cultural implications of palms up versus palms down.Quote:
Off the top of my head, you need to stay still, not run or hide, and not smile, but slowly wave your straight hands palms forward until the other being would do something.
Imitating is the best idea. But what if imitating is, for all practical purposes, impossible? The creature is globular in shape, right? How would a human body imitate it's movements?Quote:

And where would I do that? No one has met an alien yet (except George W. Bush and look what the experience did to him!!) so where would be an encyclopedia documenting the various "concepts of the exopsychology"? Can I find it at the library...?Quote:

Well, I have a tendency to imitate the people I am around (in which case perhaps my success with the alien is better assured). I can't help myself, it's completely intuitive and I cannot even explain it. I mimic their accents and pronunciation without even intending to, often. So after I was immersed in Russian for two years, it actually took me a few months to speak English normally again. Every person is different, of course. My husband could not pronounce Russian words correctly if his life depended on it. If he were to learn Russian, he would have a strong accent and it is unlikely that he would experience the sort of mental changes I experienced. I cannot even describe it, really.Quote:
Well, my native language is Russian and I live in an English-speaking country, so I'm still working on improving my English. I think I still speak Russian right most of the time. :)
Yes, that would be a very tricky situation. We would not want to be useful as food, for example. I wonder what humans would be able to provide that an alien race would need?Quote:

Or they can do some other movement we might imitate, like moving side to side, jumping or rolling, shaking, or making a series of sounds. As for the palms, the open palms are better than the clenched palms, the up and down or side movement is better than the front-back movement, etc. We can't do perfect by knowing nothing about the other race, but we can do the best we can.

I think you are right about attempting to imitate the aliens. We would have to try, but it might easily be misunderstood.Quote:

You're right, the chance of misunderstanding is close to 100%. :) But, the extraterrestrials should also recognize that, it's a two-players' game. "We know that they know that we don't know" kind of thing. The biggest challenge is to demonstrate we're sentient and not aggressive. How would you define what's sentient? To the best of my knowledge, our philosophy cannot give the exhausting answer. So far, the easiest practical thing is to let the aliens recognize that we recognize them and we have a will. After all, they have landed on our planet, and so they should have the desire to meet us. Probably, the safest way for them would be a remote contact. And the contact is perceived through the senses which let us perceive the reality which for us is a combination of the fluctuations of the electromagnetic field. We should expect the ETs to communicate through those channels, so if they chose the visual spectrum that might not be a real alien, but a hologram of one, or a hologram of a human, etc. For a practical contactor, that should not make much difference. So, yeah, imitate and try to make the alien imitate you. Then, I think, comes the step of demonstrating our civilization is technical. That means, you should make a straight line and a circle with your finger on the sand. Then, pick up a small object and do the same. This way you demonstrate our civilization uses tools and abstract concepts to manipulate the reality. :)Quote:

No, I didn't have a chance to. Would you recommend it? Also, if you search under "astrobiology", "xenology", "xenobiology" and "xenopsychology" you will find more resource online.Quote:

Here's the beautifully-done opening shot... note that the very last radio signal we can hear from Earth is FDR saying, in March 1933, "We have nothing to fear but fear itself":

I used to run it, but now I intentionally do not. For what it's worth, I think it's a neat way to catch an extraterrestrial computer virus. Even if aliens know nothing about our computers, they can make some assumptions and given the timeframe and the sheer processing power that the distributed computing provides, they can make it work. It least, it's easier to make some assumptions about an unknown computer than some assumptions about an unknown form of life. What do you think of that?Quote:

Aha, translating into an everyday language - you don't believe that's possible, do you? ;)Quote:

The guys from the 60-s believed an extraterrestrial civilization would send out an electromagnetic signal of its existence hoping another civilization would catch it, distinguish it from the noise, and send a similar signal back notifying the other civilization they are not alone. The 'distinguishing from noise' algorithms should analyze the entropy of the signal this way or the other. That means, from the outside, the whole SETI system looks like one giant computer which at the very low level has the same logical operation. For example, an entire computer of any complexity can be built by the logical units which only implement the primitive NAND operation. Once we know that the computer is NAND based, we can make further inquiries and find out more about its structure and gradually build a high-level application which does something useful to us. Of course, the NAND units would not know anything about it, they would continue analyzing their low-level input and produce the low-level output. I think, it is theoretically possible to do the same for the SETI@HOME. The system would not know it is actually processing the high-level program.
Let me explain the need for that as well. It's true we want to know we're not alone, but that is not everything we want to know. Let's say you sit in a cave with some other humans and you want to let the humans from some other cave (which existence and location is unknown) that you're here hopeful they are friendly and your cooperation would be appreciated. However, is the best way for that would be get out of the cave and shout out loud: "Heeey! Is anybody heeere?" Because, a hungry saber-toothed tiger would most likely visit you first. Therefore, you should avoid the not-so-smart shouting, but think of some civilized way to get some information first.
I think the SETI and METI are the legacy of the analog communication of the 60-s and 70-s and are not relevant today. I think, if we want to look for the other civilizations, we should get some info from them first, and only then make a decision of whether to reveal ourselves or to stay in the shade. So, if we'd had a computer program which could penetrate another civilization's computers by masking itself as the noise, detect what kind of elementary programming operations the computers use, gather information and send it back, that would be much more useful and safe.
And if we think it's useful, why the other part will not find it useful too? ;)
That makes a lot of sense, Crocodile. I would tend to agree with you. I think, however, that we have already shouted enough times to alert any saber-toothed aliens in the universe to our presence. All of those messages we sent are out there already. We cannot retract them.Quote:
I think the SETI and METI are the legacy of the analog communication of the 60-s and 70-s and are not relevant today. I think, if we want to look for the other civilizations, we should get some info from them first, and only then make a decision of whether to reveal ourselves or to stay in the shade. So, if we'd had a computer program which could penetrate another civilization's computers by masking itself as the noise, detect what kind of elementary programming operations the computers use, gather information and send it back, that would be much more useful and safe.
Do you think maybe we have already doomed ourselves? :sorry:
I think we've done a lot of not-so-smart stuff. I think we should at least start moving into the right direction, stop shouting and stop letting 'the noise' from the outer space enter freely into our computers, stop intensively process it the same way each year, putting more processing power into it every day (and being proud of it). ;)Quote:

That is really interesting information, Crocodile. Thank you for sharing it. I do not run SETI myself, but I have friends who do.

The non-human intelligent beings are already on our planet! :)

ha!! Crocodile, have you seen the movie "The Cove" - it is about a horrible place in Japan where dolphins are slaughtered. Very sad, but the journalists who did this story were very brave, I think, to expose this horror. Dolphins are extremely smart, smarter than chimpanzees. Octopus are intelligent too!

By the way, did you choose your name after the old Soviet magazine "Krokodil"? I have a stack of them from the Brezhnev era! :thumbs:
No, I had a different reason for pick up that nick. :) I'm not sure what the latest developments are in the dolphin's study, but apparently there's some strong evidence for the dolphins being a bit more than just very intelligent animals.
It would not surprise me if there are many animals that are more than just "intelligent animals." We assume that because their languages do not rely on spoken "words" like ours, that they are not sentient. Who really knows what sort of languages they speak? If humans were psychic, for example, or could transfer our thoughts to others via telepathy, why would we even need a spoken language or words?
