Carl Sagan on advanced civilizations

[VerseInfinitum]

The civilizations that survive with advance technology acknowledges such technology to be a delicacy and not an extension to one's self to serve one's self. Any civilization for which their social advancement outpaces their technological development would be best qualified to achieve Civilization Type One or Two status based upon Michio Kaku, Nikolai Kardashev and Robert Zubrin! Such a cosmopolitan society would be post religious and post Darwinist who are self governed and grateful.

[daemonboi2]

kinda mind blowing

[clovano]

If I had a nickel for every pixel in this video, I'd have a quarter.

[Kaeralho]

@clovano lolol

[ZildjinIsTaken]

We can only hope alien species are less intent on destroying themselves than humans are.

[wybo2]

@ZildjinIsTaken Errrmm......What?

Did I miss a memo?

Did the human race distruct itself last week?

[ZildjinIsTaken]

@wybo2 keyword: intent

[latinoheat300]

@wybo2 Indeed. If anything in due time WE will be the older and wiser civilization making contact.

[utube2344]

he is very smart but are we so arrogant to assume that all intelligent life can only discover the certain types of technology that we do at certain time periods? Perhaps others can discover a new type of technology which may be viewed as more primitive than our current civilization but a whole new type of tech. What if the universe is infinite? There are really so any mysteries we have barely even tapped into what reality is.

[xbuster17]

omg carl sagan was a pothead? amazing! legalize it NOW !. for us may never reach type 1 civilization without cannabis !

[starlogic99]

10 per galaxy is actually a lot

[Viperatti]

@starlogic99 10 per galaxy is a lot? Yeah but if that's one planet in our galaxy sparks intelligent life every million years, chances are we would never exist at the same time...

[odysse14]

what year was this made?

[LBJTV]

@odysse14 Don't know about the exact year but it's obviously mid-70s

[odysse14]

@LBJTV how is it obvious??



[LBJTV]

@odysse14 Well, the clothes and hair give it away..

[odysse14]

@LBJTV Not really...there's alot of people who have still have the hairstyle and sometimes the clothes...

[LBJTV]

@odysse14 Yes, but c'mon, Carl Sagan isn't from the 1940s is he? At the age he looks here, it was the 70s..

It's like watching a video of Marvin Gaye in a white leisure suit, red silk ruffle shirt with an open collar, and platform shoes..it'll obviously not be the 80s but rather the 70s..

[odysse14]

@LBJTV he has to follow all the trends? nope.It could be the 70s or 80s.

[LBJTV]

@odysse14 Look, this is from Cosmos, his tv show..and I know already know this particular episode is from '74-75..

The appearance is just a back-up justification for somebody who doesn't know that

[odysse14]

@LBJTV yes,i didnt know this...that's why i asked-duh..but my whole point was it isnt obvious...Clearly-if it was obvious I would have known :/

[LBJTV]

@LBJTV It was actually from 1980.

[loosekarrott]

suddenly math is interesting

[fballplayer2324]

this guy is my biggest hero because he was a huuge pothead. o you thought weed made you dumb?

[batistaker123]

@fballplayer2324 So many successful potheads out there people just don't acknowledge them lol

[HambleThornberry]

@fballplayer2324

It depends on the person. Some people cant work while smoking weed, some do it when their off work, some on the weekends. I persume that Carl Sagan didn't really do it ''on the job'', but im sure he did it at home and when he wasnt doing much. It all depends on the person, some just cant work while they toke and end up doing nothing and going to sleep. Im one of these type of people.

[hybriddefect]

What about the ones that get wiped out by something more aggressive. A community can be completely docile to each other and downright savage to another community.

[JohnF30Music]

shit, if i was gay, i'd be sagan's lil bitch. he's the man.

[2pacalypse25]

@JohnF30Music what the fuck dude, haha thats a weird thing to say

[jedirambo]

@JohnF30Music : Your language is crude but the statement is correct.

[taicleis]

@MaoiMaea

... nor can we begin to calculate the innumerable potential exceptions to our understanding of a 'habitable' world.

[taicleis]

@barto11000

Sagan does not dismiss their claims out of hand. He dismisses them for lack of a single shred - a SINGLE IOTA - of evidence.

And even still, he does not dismiss them as you describe. He simply remarks that extraordinary claims require extraordinary evidence, and leaves it at that. Very respectable.

[barto11000]

Yet when humans relate their experiences with other beings, Sagan calls them "hallucinations", experiences dismissed out of hand, with no scientific investigation whatsoever. As the saying goes, 'white man speak with forked tongue.' And the other saying applies with this clip here also, 'figures don't lie, but liars do figure'. This guy is nothing more than a cliche.

[duchashes]

the cosmos could be many many times larger than we think it could be that each galaxy in the universe is equvlent to each atom in a galaxy

[charlieking100]

Miss you Carl!!

[MoaiMaea]

Hahaha, Carl Sagan is full of shit. The opportunity for life as we know it to occur lies between the freezing point and the boiling point of water which means in the small range between 273 and 373 degree Kelvin (out of the million degrees of the temperature array in which cosmic matter exists). For advanced life forms to emerge this small range has to stay constant for billions of years. In case of our Earth with its oceans this is the case because of its exact distance to the sun.

Part 1

[HotaruZoku]

@MoaiMaea You're basing the ability for life to exist within a near, if not totally, infinite cosmos on the understood climate of -one- /form/ of life? Us? How can that reasoning predict the existence of anything at all but ourselves?

How does it not pre-suppose an assumption I find, with all due respect, to be short sighted: That the only way anything can exist...is if it exists JUST like us?

[MoaiMaea]

As far as I can tell the current theories concering life based on other elements than water and the like are woolly at the best ... so yeah, since we can’t tell if life is even possible without aforementioned elements I didn’t bother including them in my thesis. And I clearly stated that as well, did I not? Besides, what are you talking about an infinite cosmos?

[TralalFace]

@MoaiMaea stfu you stupid ignorant tool face gtfo hater

[MoaiMaea]

Put a shirt on, you little joke.

[instereovideos]

What is Carl Sagan doing in my living room?

[Scrumpilump2000]

I wonder how recent scientific discoveries would alter the Drake equation. I'm talking about things like (a) the discovery of a slew of extra-solar planets, (b) the discovery (proven?) of there being more red dwarf stars in the galaxy than previously thought, something that would increase the total number of stars by up to a third, and (c) the tantalizing discovery of the organism that has incorporated arsenic into its metabolism (as an example of extremophile life forms). ???

[DandAinTac]

@Scrumpilump2000 This is a great question. For example, he estimates the number of stars with planets at 25%. I'll bet many astronomers would put that number a lot higher now. Also, given what we now know about "extremophiles"--those organisms who survive and even thrive in very harsh environments, I think the estimate for the number of planets on which life arises would probably also be higher. Where the numbers will pare down dramatically I think, is the last few parts of the equation.

[DandAinTac]

@Scrumpilump2000 I ran this equation through other assumptions I made with new discoveries in mind, but with more pessimistic numbers for the later parts. My estimates yielded high numbers for the number of planets with life, but very low numbers for the number of planets with advanced life capable of interstellar communication.

[Snowmoto]

Thats the Drake Equation...damn I love the "life in the universe" class I'm taking at my college B-) and Carl Sagan!

[istvanklein]

I'm inclined to say we're alone in the galaxy at this point of time. This is not to say that other civilizations have not emerged, or will not emerge, somewhere else, but the time scale is so enormously long that it's perfectly possible that no two civilizations exist alongside each other at the same time. Others may have gone billions of years before humans appeared, or will only emerge billions of years after we have gone.

[AcronymEjr]

@istvanklein I hear there's a video somewhere on this page discussing the possibility of other civilizations in the galaxy! It even has some calculations which include the factors you mentioned! You should check it out.

[istvanklein]

@AcronymEjr There are a lot of other videos discussing it but most of them have the same thing in common: as we haven't got a clue about several key factors, all calculations are bound to be based largely on speculations. So is the Drake equation, the most famous of them. The chance of SETI or any other search projects stumbling across other civilizations that are close enough both in distance and the stage of development for us to be able to detect them are infinitesimal.

[AcronymEjr]

@istvanklein Well, my point was that he took the time scale into account and tried to incorporate it in to the formula (correctly or not). You just said that the time scale is so large that it's probably unlikely, a strangely unscientific/unmathematic comment on a video based around science/math. You also changed from "other civilizations in the galaxy" to "other civilizations close enough to us."

[istvanklein]

@AcronymEjr You're right, my comment is indeed unscientific and unmathematic, as I am neither a scientist nor a mathematician, just someone who is a compulsive reader of anything about SETI. But I do think we can agree that the current SETI approach is not much more than looking for a tiny needle in an almighty haystack, with no-one having a clue about what exactly to look for and where to look for it, and how.

[istvanklein]

@AcronymEjr And given our still very underdeveloped detection technology, ET must be close to us in cosmological terms for us to be able to spot them. And also close to us in terms of how developed they are. And we don't even know that they use radio technology for communication, or something else that we wouldn't be able to understand. Putting all this together, it seems very unlikely that we will ever find someone or something out there.

[tomdugan123]

Fact: Carl Sagan is only pointing out the obvious. We Humans love to dream up

movies and write novels based on E.T. All he is doing is showing us how likely

it is that we are right.

[615Deathdealer]

To believe that Earth could be the ONLY planet to ever support life in the galaxy let alone the universe is narrow minded and foolish.

[marineaddict]

@615Deathdealer thats what i think.

[profjaykay]

@PeterRoeder31 how is it impossible to believe anything?

[profjaykay]

@PeterRoeder31 wait what are you saying is impossible to beleive? mabye i am misunderstanding.

[KenyanObama]

I'm not religious so naturally I'm not taken in by Darwin's Sumerian-based fantasies. Dogmatic Darwinism proves nothing. It merely extrapolates beyond human reason, without 1 viable (to date) human ancestral relic, that Man's impossibly-distant ancestors were caudates. Darwin's lickspittles are under the misguided impression that the burden of proof, in what they suppose, is not incumbent upon those who make the supposition.

[GRIJZEKAK]

@KenyanObama : can you explain what you mean in easy language?

[KenyanObama]

@GRIJZEKAK : I will not.

[GRIJZEKAK]

@KenyanObama : k then mister friendly. what's the point of a message?

[MrAdee28]

sagan is punk rock!!

[lacquercandy]

And out of those millions of civilizations that are advanced, how many grow through the dimensional barrier? How many outgrow physical reality and move on to higher realms of perception? Most I bet. And that is why we cant find "proof "of them. We can't perceive the "proof"

[dayoflords]

Why do i hate this guy

if he smoked a lot of bud i wll let him off

[Ulrna]

It's funny, grooming the majority in just the right way makes them purr, but if you groom them the other way the hiss and claw at you.

As smart as Carl Sagan was, even at philosophy, he never did void from the common understanding of alien life.

Back then lack of understanding on terms like psychology and metarhetoric was kind of cute, but now when liberty is collapsing in on itself by defining people as terrorists and denying them human rights, it’s a little more serious.

[TheHawkdaddy]

Carl Sagan lays that shit down. His shit will fuck you up son.

[vdubwhore]

I watched Carl Segan when i got high all the time when i was young .He got me to love science.....crazy.

[sirbata]

For a Scientist, you Sir are using way too many assumptions. And your formulas are WAY wrong.

[JoeyCage]

jam this shit "Symphony of science"

[StarvingForTruth]

I mean, it's theoretical right now, but the string theory crowd postulates something like 11 other dimensions intersecting with our own. How do we know the UFO's travel great distances in anything like the way we think they do? How arrogant is it to suppose we could imagine every future possibility as our own technology grows from technological infancy over another million years?

meh. Sagan was a pompous stoner hack who just liked the sound of his own voice, like stoners tend to do.

[Isnaard]

@StarvingForTruth Lay off the ad-hominems and back your claims up with good arguments and scientific proof. For now we lack any of any advanced civilization.

The threat of destroying our own species and taking some of the earth with us is pretty big, and I hope we can get through even though the economical and religious pressure that makes it difficult for science to create solutions.

[StarvingForTruth]

@Isnaard i don't need you advice to make a point, and i don't need to 'prove' carl sagan was an arrogant ass. EVERYbody knows that. it wasn't exactly a secret. no, i won't source it. i don't care to. if i made an argument that required proper backing, i'd do so. but i didn't. i was just talking about sagan and his shortcomings.

quit lecturing and fuck off.

[adamjrusso]

@StarvingForTruth looks like you're a scared little christian who's more starving for attention than truth.

Here's another point I need to make and don't need to prove because EVERYBODY knows it. Your assessment of a man who now 14 years dead still means more than you do, and more than you ever will or will hope to be. It's not exactly a secret you're a little bitch who will cry to mommy now that I hurt your feelbads. Quit being a faggot and fuck off.

[StarvingForTruth]

@adamjrusso lol. and you're an idiot. no, i've not ever been a christian, or anything else for that matter. and no, i have no hidden aspirations to be just like carl sagan - not in the slightest. it's true though what i said about him. i know you're kind of just a stupid kid, but ask a grown up who was alive to know the man's career. go to the library, and find articles where people expressed their opinion of the man. he was a world class asshole.

now be a good kid and mow my lawn

[adamjrusso]

@StarvingForTruth faggot, you don't own a lawn. You likely don't even own your computer. It's probably some throwback piece of shit that you picked up at a pawn shop or on the side of the street.

Your hidden aspirations may be to waddle your fat, loser ass up out of your parents basement and maybe see the sun once in your life. It's a lofty goal. Grab a few twinkies and try again, you might make it one day.

[StarvingForTruth]

@adamjrusso

faggot? tard? you're on a roll!

i have my own business and home, in a really nice town i might add.

you're fucking cartoon.

do you masturbate to this video?

grow up, shit head.  go read a sagan biography and shut your ignorant fucking trap. prepare to feel stupid.

[StarvingForTruth]

it's DUMB to assume other civs would communicate how we communicate. that we'd assume they transmit information using the same mediums.

dumb to assume what we think is possible, is what's possible. anyone with his knowledge of the history of science and the pursuit of truth should know better. but of course, men like Sagan and Shermer don't care about truth so much as attention. Vastly egotistical little hacks these men are. Disgraces to science and true open minded skepticism.

[Isnaard]

@StarvingForTruth

It's dumb to assume everyone who thinks differently than yourself is dumb.

[toddmorrow1]

Now that Carl lives out in the Cosmos, he has the exact answer to this formula.

How about a little help, Carl?

The number of stars of a certain age that have planets is closer to 100%, and the fraction of a planet's life that it hosts a technological civilization ought to be higher than 1/100,000,000. 

[charlieking100]

Carl Sagan - legend

[historyguy10]

Carl Sagan is sure a dreamer. But I guess that all human beings have to have something to believe in. I will give him credit for having good speaking skills. His discrptions make him sound as if he is omniscient.

[FiverBeyond]

"It's hardly out of the question that we might destroy ourselves tomorrow."

Ah... Dr. Sagan... we miss you so much.

I'm always very skeptical of any claims to predict the chance of life evolving (in truth, I think that every last one is strictly conjecture). However, Carl Sagan seems to be very aware of which numbers he is making up, and the inspirational concept is the same.

The best math I've heard on the issue is that we're either completely alone, or overcrowded!

Calvingmail, you can't just say "God made the planets..." etc and expect reasonable people to just all of a sudden say to themselves...."oh, of course! My entire belief system has been wrong all this years! Thank my newly found God that Calvingmail came along and made it all so clear." I won't argue with you though....you obviously know it all.

[calvingmail]

God made the planets and created life...there wad no evolution..Carl Sagan knows this by now...LOL

[gootmusic]

@calvingmail you want someone to write you back and disagree SO badly, don't you? So you can argue, and re-affirm your beliefs, eh? Pathetic.

[thissystemneeds]

I know I'm just being baited here, but I have to comment.

First off: Proof? Where is it?

Secondly: Carl Sagan is _Dead_ I don't think he's knowing anything right now. His metabolic processes have ceased. That has a habit of stopping your thought processes.

and Thirdly: You, my friend, are a moron. Carl Sagan was one of the finest minds in theoretical science, and humanity thanks him for his contributions to society.

[mallchris]

I saw the series when it aired originally, think of the vastness of space, the billions of years the univers has existed, also the number of extra solar planets that have been discovered, even in the last year. the earth is so small in all that space. Add to that the universe is full of the chemistry that makes life, Hydrogen, Carbon, Oxygen and Nitrogen, and also precursors of amino acids have been found in clouds of gas in space. He was a well respected scientist and we should listen to him.

[Xerxes855]

I think he way overestimates the number of planets suitable for life and the number that they developed life. But this is still a cool video!

[charlieclockwerk]

Carl Sagan was and still is awsome in whatever galaxy he is soaring through at light speeds.. People knock this vid, but what is wrong with making a very logical mathamatical equation to try to figure out what the universal language ( math ) has to say about it.. bitches ! ! !

[samymh]

Was this an anti-nuclear weapons movie by carl??

[RichardMNixon]

Now I only have an engineer's understanding of biochemistry, but for Ne, are we only looking for the existence of life similar to ours? Couldn't there exist other kinds of life that could exist in a world lit primarily by UV light, or that could live in ultra high gravity, or below freezing temperatures? Could intelligent life evolve without depending on liquid water?

[tastyscavenger]

@RichardMNixon

yes Mr. Nixon but it would be very hard

see the wiki article on "Hypothetical types of biochemistry" to see why.

[migduh]

"A hnnnndred bullyon"

how much do I love Sagan? Really.

[WildSilent]

Waiting for a 'signal' from other intel. life from far away galaxies is not a 'logical' probebility , it is more like an story for a film, well, in that case, Okay, no one is perfect, lol,

Those who are 'waiting' for a inteligent life's signal from other planet is all about saying 'human is not the only inteligent life' around, lol,

Man is funny.... : )

[WildSilent]

Do not push it that unlogical, we are ALL ALONE !

UNTIL, we are 'not' alone!.

: )

[jileel]

interesting i love carl sagan rip

[mahones64]

why does he say 10 planets?

[ieslsei]

mahones64, this is because he just want to make an estimate of the order of magnitude, so picks up "10" to conveniently use in the calclulations.

[Valentin0o]

God, when the hell are we going to get out there?

[inuki69]

i think if there are advance civilizations out there they wont be interested on a small and primitive planet (i.e. earth)

[ThePeacemaker123]

of course they would be interested in us. just look, how we are cataloging the smallest bugs here on earth.

[Itsnick85]

Agreed.

[Wormhole908]

I believe most civilizations will be more interested in making contact then trying to take over our planet.

[ThePlaneTruth]

If we've been visited by alien civilizations and have not been taken over by now, then once we get out there we will kick their space butts and rule the galaxies...

[nickstemoeilijk]

We'll soon find out if civilizations destroy themselves.

[Deshara218]

Many civilizations didn't, really. If we end ourselves, it doesn't mean that civilizations are doomed to fail miserably, only that we have driven ourselves to fail miserably.

Translation: You have a mental capacity less than that of a common 7th grade student.

[internaut101]

because that requires an almost unbearable stretch of the odds. It requires a class II civilization at minimum for any hope of solar system travel and us being alone so far and less than a class I civ, it is impossible for us to calculate the odds that it DID happen and apart from the also meager odds that it COULD happen there is meager evidence of it HAVING happened.

[carveyournamein]

Earth is a class 0 galactic civilization.

[internaut101]

granted; less than 1 class can be 0 class

[carveyournamein]

What is being implied is that we have no way of measuring what we might consider lower than class 1 in the example, so Earth defaults to 0 until we could assess otherwise.

[brvslugger10]

if he says there are this many civilized planets, then why is it so hard for him to believe that aliens have visited our planet?

[8tripsaweek]

subjectivity and unscientific methods for testing abductees, along with lack of physical proof. i would love to experience contact in my lifetime though. fingers crossed, now only if i could believe in that helping :S

[Seldingereve]

Because of the sheer number of potential planets

[carveyournamein]

You weren't paying attention to what he was saying, dumbass.

[CommanderUTube]

1 billion civilized planets ! Holy smoke, my ambition to conquer the cosmos and be the Universal Emperor is defeated by the sheer number of stars. : )

[SkinShandeler]

rodo was right. my bad. but you have all those goldilocks zones any planets close to the center of the galazy automaticly are eliminated. so it woud not be 400 billion per galaxy. Billions would be eliminated from that number. so i dont know need to re equate that...

[zummarago]

What we do changes the equation don't you all see?...It doesn't matter that most people hav eht esilly notion of cause and effect, how we behave makes us or breaks us

[greger4520]

Nice explanation of the Drake equation.

And you are right, rodorvh. If we include the number of galaxies in to the drake equation, I think its in the neighbourhood of 100 billion, then we get a much higher number of civilizations.

I always liked Carl Sagan, but his voice sounds kinda silly to me. Like the voice of a goofy minion to the Bad Guy in a saturday morning cartoon from the 80's.

[rodorvh]

Sounds pretty reasonable to me. Very interesting. If thats the case 4 our galaxy only think about the hole universe. Special thanx to Chuky DK 4 posting this extraordinary clip.

[SkinShandeler]

no dude thats for the unierse not just our galaxy

[Davey850]

No, he said "our galaxy".. find it that hard to rewatch a video of 7:47 min?

[carveyournamein]

lol. people are morons and always will be.

[Itsnick85]

Most of them. 80+% at least of ALL humanity. Places like india and China probly closer to 99.5 %
