Carl Sagan's Cosmos Episode 2 part7

[joppadoni]

i think the likelyhood of a god is about equal to that of quarks forming atoms to form molecules to form life without the idea of predestined requirement to form life/anything in the first place. seems idiotic the complexity of everything is random. but hey if i wanted to know/no longer care theres plenty of bridges around... lol :D it is nice to just marvel at it all and wonder.. or maybe kill others who dont agree with you ^^ whateva ya pleasure i guess :S

[elmonorizzo]

i had no idea he imagined life on jupiter that's awesome

[bingofingers]

Why do scientists keep saying life on other planets is 'likely'. Sagan said it, Hawkins said it and Dawkins says it.

Nobody knows how likely it is that life evolved at any of the crucial stages. Based on one event you don't understand it is simply not possible to predict the probability that it will happen again. It doesn't matter how vast the universe is; you can't say that it is probable that life is common if you don't know the probability.

[InfinityWarriorInc]

Hypothesis: If just all species of dinosaurs died, could it also have been a pandemic that only affected them?

[tsartodd]

(beavis & butthead voice): LOL "Floaters"

also, i love the idea that there could be planets that look like Roger Dean-drawn Yes album covers XD XD

[aquanaut145]

I wonder if Carl Sagan ever read Bernard Werber's book ''Empire of the Ants'' I'm sure he would have enjoyed it.

[goldenrod4]

1:15 we call these creatures... koffing

[Embraer091]

I'm 21..I really miss guys like that nowadays..Those episodes go far beyond from a religion issue.I believe in God, but the fact of believing in God DOES NOT prevent me from wondering how things work or how things were made.People are used to believing in God and consequently think that everything were made as fast as a blink of an eye (That's totally unacceptable)...I really feel sorry about those people. If I am right and God really exists, he must be thinking how stupid we all are.RIP CARL

[sneeb]

This is masturbatory. For all we know, x-7g flexes have eaten their way to glory.

[artugal86]

Oh how I would have loved to have shared a joint with this man and listened to some of his stories, theories and opinions on everything. R.I.P Carl Sagan and thank you for being who you were.

[MisterEvasion]

Another reason for longing for the days of the 1980s was Carl Sagan. He was a regular on late night talk shows and had featured articles written by and about him in many science magazines such as OMNI throughout that decade. OMNI itself was a 1980s phenomenon too, that died around the same time as Carl.

[karkovice10]

Wow! Dr. Sagan has certainly aged in the span of 10 years!

[Jammed9000]

@karkovice10

He was VERY sick you see....

[MindAndMarzipan]

I love you, Carl. TY for getting me started.

[cicero1453]

I wonder if Uranus might contain sinkers and floaters.

[SanGuevara]

My brother, the scientist of the family, said that once energy enters a system it cannot be nullified, and that this same principle applies to the universe. Did Sagan say anything about this? Any thoughts?

[3LARI]

@SanGuevara yes that's the basic conservation of energy principle. The result is that energy can never be created or destroyed, it can only be turned from one state into another. Its what SirNewt was talking about above. The atoms that make your body will always exist in one state or another, as long as the universe does. As for applying that principle to the universe as a whole... well that's above my head :)

[iraul20]

@SanGuevara He said that once energy forms it cannot be destroyed

[arvinart]

@SanGuevara its true. energy never dies it just changes to other forms of energy, even a desk has a form of energy which we call it potential energy. In space if you push an object such as a book or a chair, the objects starts to travel to the direction that you pushed it and you will start to travel the opposite way and this traveling will last forever unless a source of gravity such as planets moons black holes or wormholes change ur direction.

[Scast046]

I've been thinking about something new lately. About the possibility of multiple realities. Now we all ready experience 2 of them on a daily basis. One being the normal life after we wake up from our sleep. The other being the world we live in as we sleep. The are different, but our brain tells us that what we dream about feels real. I doubt the possibility of a rebirth, for the simple fact that we don't remember anything about our formal lives if it did work that way. I think maybe when you die

[obbabob]

Was Carl Sagan an alien?

[aboveyourself]

Byebye Mr. Sagan :[

[euphoritch]

what a elegant mouth this man has ...love it to listen to him . never heard of the person

he makes me change my mind after \each vid , just a litle more ....i learn quick with this kind a education...how about you guys?

[sammara60]

fat bastard left a floater

[ThomasHaberkorn]

my god.. 2 beers and vangelis givea me goosebumps

[euphoritch]

hahahaha , the right subject aswell??, the music is beauty....also a story of the universe .

like your comment!

[Benjamin666face]

I've definitely seen some vast, buoyant floaters in my day. Floating in a rapidly swirling ocean of toilet water, blown over the four corners of the bowl by a ripe, brown breeze.

[jonathanswift]

floaters the size of cities

after a vindaloo, maybe?

[petergao15]

What I wouldn't give for him to update us again, today. :(

RIP Dr. Sagan.

[Zee96969696]

i still can't get over the fact that carl sagan talk exactly like agent smith from the matrix

[48Donbray]

Seeing what we know, and what is possible, it's amazing to me that there are still a majority of the population that believes in things that can't possibly be true, or realistic. Knowing whats out there, and assuming that it's the same throughout the universe, is just ammmaaaazzzinnnngggg.

[mandolinroad]

@48Donbray My thoughts exactly.

[Zee96969696]

you're just a moron what would you know? i don't know, i just know that what you don't know you may or may not know, look your a little confusing, just except the fact the nobody knows anything for sure ok? we're all just taking the best guesses that are available ok? look, you made me a little upset

[48Donbray]

@Zee96969696 - actually, I'm not a moron. But thanks for the attempt at summing me up from my two sentences I put on here. Looks like you have thought about it yourself a bit, and are aware that it might be true, and you feel guilty about it. Good guess? How do you like me telling you how you are? Take it or leave it, I don't care, but your delusions will show it's true colors eventually. You know it, I know it, and the intelligent one's know it. Funny, you get upset? Hmmmmmmmmmmmmmmmmmm

[Zee96969696]

i don't understand what you said there, look, carl sagan said that those creatures are plausable on one of the planets like Jupiter thats all, he may be right and he may be wrong, I think that carl sagan is right about alot of things but even the smartest people on earth can be wrong as well, chris longan i think is wrong about alot of things and is also very right about some things.... but carl sagan is talking science, he's a scientist, plus he mentioned that those creaters were just fiction

[datalal624]

Ah... The music of Vangelis. :)

Thank-you, Carl. We miss you!

[iceland111]

Awsome!

[AlphaCrucis]

That artistic image of Jupiter had been imprinted into my mind when I was, possibly around five years old, in a book, and now it has finally appeared to me again, this time with new meaning. The music there was very stimulating.

[themagicmusician]

Reply to AlphaCrucis: Was the book an oversized blue one entitled "Our Universe", and did it weigh a ton in your five year old hands as it did in mine at the time? I LOVED that book! Unfortunately with as many times as I've had to move, I've lost it. Three years ago in a non-profit thrift store, I came across the poster companion to that same book. It hangs in my room today.

[shalashaskalives]

Update from the graaaaave!!!!

[acs328i]

:P thats how he would want it to be!

[eggory]

Update? That's sweet. This must be from a dvd or something.

[mandolinroad]

@eggory My guess would be a vhs edition. It seems strange that he would do an update in 1990 or so and then not release it until - when did DVD become readily available? - 1997 or so?

[pioneer101112]

Perhaps this is one answer to the Fermi Paradox: Most life exists as giant gasbags in the atmosphere of Jovian type worlds - and most of the exoplanets we have discovered are Jupiter size or larger.

[Gazzar]

That's true but remember we are experiencing an instrumental selection effect. Large exoplanets are more readily detectable than smaller and less massive worlds, hence we are more likely to find them given our current technology. Small rocky worlds (or the moons of giant planets) are currently below our detection threshold - although mayeb not for long. I do wish Carl were still here to appreciate these new discoveries.

[coozno1977]

Like a galactic seed/flower pollinating the universe.

[DjimonMoz]

wow those floaters look awesome

hehehe I wish they really existed, I'd very much like to see one

[Farcallo]

The first.

[Farcallo]

Whats the name of the soundtrack at the end?

[DaveLH]

"Entends-Tu Les Chiens Aboyer?" by Vangelis. It's on his album, _Ignacio_, as well as the compilation album, "The Music of Cosmos".

[feifeishuangyu]

My dream is to return to star.

[GoldenDynamo]

To me, the idea of a god is as likely as 1 in a googolplex, and the idea of an afterlife is absolutely implausible.

[SirNewt]

I find this stance as unsupportable as that of total faith in an afterlife. We have no idea, the impact the rise of consciousness has had on our universe. I find it possible that morality, justice, a god, and an afterlife are all real derivatives of the emergence of consciousness.

[TheArcaneAvenger]

Would you care to expound on that?

[TSBoncompte]

@SirNewt I, on the other hand, find your stance either unsupportable or irrelevant: you say that afterlifes, gods and other such supernatural phenomena are possible. sure! they are possible, anything is possible! it's also possible that there are teapots floating around in intergalactic space, or strangely carved sculptures of octopodes laying in the center of the sun; both of those are possible, strictly speaking, but they're really unlikely and their non-impossibility is irrelevant.

[oneplusonewd]

@SirNewt and yet that possibility has no support either. Empirical evidence of the laws of nature teach us nothing of a supreme being or an afterlife. So why waste time in even considering the idea plausible? It is not demonstratable and therefore has no meaning.

[3LARI]

@oneplusonewd Well yes, you are right. If to judge your correctness you are using the limited criteria of human knowledge. Stranger and stranger things are discovered as time goes by that we would have thought nonsense in the past. I mean who just 500 years ago could have contemplated the computer? I'm not saying there is a supreme being or afterlife but the world keeps throwing up surprises. Just keep an open mind. (Shit I nearly sound religious! (I'm not! (honest.)))

[oneplusonewd]

@3LARI and I wholeheartedly agree! My argument though is that if something can't be falsified then it is a waste of time believing in it. I love that science is continually changing and updated it's own knowledge-base and old theories are either discarded or built-upon but religious dogma teaching that there is only 'one' truth that cannot be falsified...waste of time!

[shrikechan]

@oneplusonewd You woud think this was a shocking new idea going by how many people are still so determined to believe in things for which there is not even the faintest trace of evidence.

[oneplusonewd]

@shrikechan let's just 'hope and pray' that those people have an 'enlightened' moment and see the truth for themselves.

[shrikechan]

@SirNewt What good is an imaginary God compared to an actual one? If God is merely a superfluous side effect of conciousness and not the creator of conciousness then there is no reason to call it God. Morality exists reguardless of whether or not it was given to us by a God, as is the idea of justice. And as there is no evidence for God or an afterlife and since an afterlife would be meaningless compared to life itself, it`s hardly radical to say that these things are implausible.

[ericberner]

@SirNewt Well put. It seems the great enlightenment is over and were heading back into the darkness of absolutes. There are so few absolutes, and even they are under constant and well deserved attack.

[thedarkarse]

@SirNewt

...more or less agree. At the end of the day we know cursed nothing.

[FFFurken]

@SirNewt " I find it possible that morality, justice, a god, and an afterlife are all real derivatives of the emergence of consciousness."

You lost me at "god".

[moechaputida88]

@SirNewt I find your last sentence as unsupportable as that of total faith in an afterlife as well. Morality and Justice have no meaning without humans, yes. But How illogical it is to believe that a God and an afterlife can be created simply by molecules becoming conscious of themselves. Life is a wonderfully incredible phenomenon, but it is entirely allowed and even encouraged by the laws of physics...how then could it be that an entirely natural occurrence has supernatural results?

[askjiir]

@GoldenDynamo

Which you base on cluelessnes. Fail.

[thatguy431]

sagan aged so much in the cosmos update portion....what a good guy, wish he was still with us

[alltheworldsastage]

still missing Sagan........we need Sagan.

[prayfertrey]

Yeah, but... I don't put all my hopes in this universe simply because my stay here is so short. Everything in this reality is temporary. That seems like a huge clue that this life isn't everything. The only point in this life can be to not leave a mess for those who come after, just as a courtesy; but beyond that...

[SirNewt]

Everything is temporary except for everything. Long after you and I are dead, and the human race is gone, all the atoms, every one, that made every person who ever lived will be spreading and cooling or will be collecting and heating up. And all the energy that ever moved a human's heart and lungs will be the work pushing those atoms out into space or will be the heat and light of a new big bang. And I disagree, there is more or less to life. I'm just not sure which and what it is.

[prayfertrey]

I don't know what the phrase, "there is more or less to life" means. I just know that in a hand full of decades, this phenomenon I call "me" will be non-existent. Same for everyone else. Mankind doesn't travel to the stars (if you think anyone ever does); some people far in the future do. Everyone else doesn't. Ultimately, this is not our final stop.

[SirNewt]

It simply means I think you cannot sum up existence in one sentence. Life is worth more or maybe less than what you said. I do not know which.

[GunsOfTheEskimo]

@SirNewt

I respect you

[BjornPalmen]

@prayfertrey Wormholes in space could make trips to the stars possible,

[curzmg]

@SirNewt What a lovely and eloquently put idea, most profound because it is true. We may no longer be aware of the actions of our atoms, well in fact we aren't truly aware of them now, one day they will continue - those exact atoms - and we will continue to be unaware of their actions and processes. Our consciousness is just a temporary action of our atoms. Everything that made us who we were will still be there in a different formation. We are but a small memory in our atoms' prolific history.

[RJL738]

Scientists talk about everything from string throy, universal branes, and alternate reality, yet they never think that their may be an afterlife or some kind of God. I agree that this world can't be all their is and that this life is not all their is.

[prayfertrey]

Science doesn't address the question one way or the other; so you can't say scientists themselves never think about it. I like to think of science as poking around in God's attic. You know, we're alive, how can we not be curious about the reality around us?

[RJL738]

Agreed

[NAT4TONY]

That's because science is not responsible for or is supposed to deal with fantasy, it investigates to discover truths about the physical/biological world.

You would expect a scientist to discuss the metaphors in Shakespeare or the fall of the Roman empire.

[intermender]

perhaps our atoms and molecules will be incorporated in new life, recycled rather like the stuff of stars is.

[prayfertrey]

Yeah, but the particular arrangement that made "you"... never again.

[intermender]

yes but i'm not important at all compared to the greater reality of things except to myself as i enjoy my only awesome moments of existence in all of eternity.

It seems like a privilege to be a part of all that wonder and to be recycled into it again and again as 'i' travel across biosphere and stars.

Believe it or not, i don't mind oblivion (i'll have no mind lol) , but it does make every living moment more precious.

Thats why religion is a con: it usurps your only experience of reality.

[prayfertrey]

Well, I find it stark raving terrifying. But, waddya donna do?

[elemilex]

His conclusion about comets was just Beautiful :-)

[luicarr]

Damn the republicans and the right-wing throughout the entire planet!

[croscream]

What is wrong with you two; why do you attack people ideology like that. You can't just force socialism down someone throat, let people have the economic system that is right for them. I am sick an tired of uneducated, anti-intellectual and pseudo-religious communists telling people what to think and how to act.

[warrenstargazer]

True, or we might just slaughter them all...damn republicans...

[SardonicusRexx]

Floaters and sinkers... and Carl said he wasn't fond of Beavis and Butthead.

We miss you man.

[jetmanisme]

It's really cool to think about alien lifeforms on other worlds and what they might be like if they exist.

[SirNewt]

Surely they exist!

[warrenstargazer]

They are out there. We just have to keep searching.

[SirNewt]

Unfortunately, once we find them, if they are sentient, it may be hundreds of years before we can even communicate with them. This universe is relatively young as far as universes go. With our species on the verge of interstellar travel we may end being one of the oldest sentient species. Funny, considering how humans are always depicted in fantasy fiction.
