Carl Sagan explains the fluidity of galaxies

[rodzimanos]

What i really excited about is that this movie was shot between 1975-1980 and it remains classics forever. This is great contribution to the popularization of science. I believe Carl Sagan dreamt about the scientificaly and technologicaly developed society. What an unordinary dream!!!!

[rodzimanos]

This is so true Drake Magnum!!!

[Southernburrito]

Gosh I really like this stuff :) I don't see why not?? I mean after all we are a continent & ocean away from Jerusalem. Not try to tear anything down with that but only validate. Amos 5;8 Pleaides & Orion, Acts of Apostles & the Grey tarp shaped thing that dropped down & let animals out of it? Demonsions, Neitherworld, Revelations & House of Hades. Solomon talks about when beings came down. It gives credit to celestial beings. White Throne God of Universe, Earth & Sky fled froms presence.LE-bang

[bboyCrazyLegs]

Fuck these ads! No, I don't want a psychic reading?! I just want to listen to Carl! Holy fuck..

[ptl79]

@bboyCrazyLegs you can disable most of the ads in 'settings',

[humand1saster]

Carl Sagan really loves what he is talking about, and that is exactly why it is so easy to pay attention to these videos. I think if I had been shown this when I was in school I might've paid more attention

[hookahhookah53]

@humand1saster You are so freaking right. If you don't remember what you're comment was about, it was about how so much easier it would've been to pay attention to Sagan's videos.

[rodzimanos]

humand1saster: True. Carl Sagan is outstanding personaly because of his passion demonstrated in creation of this movies. He is a personality and inspirational teacher.

Everything in the universe is traveling through space-time at the speed of light - the maximum speed possible. If you are sitting still in space, then you are traveling through time at the maximum speed. But if you begin traveling through space, then your progress through time slows down.

[420GlassArt]

Fluidity is a big fan of Carl Sagan

[1unrealworld]

my brain just got fed a full course meal. I'm stuffed! Thank you Carl Sagan!

[420simpson]

isnt is sad that more people look up to paris hilton, lady gaga and justing beiber, that people like carl sagan, sam harris, richard dawkins, and stephen hawkins.

[Invisiblefiyah]

youtube has immortified sagan.

[KazumaKyu]

@Invisiblefiyah Immortalized?

[YuCme93]

the ego created hatred. God has a purpose i.e 2012, there is no death only to the fals mind made self of the ego

[TiTSxxMcGEE]

god i wish he was still around. listening to him makes me feel like everything is okay as it is. everything will be alright.

[Elizza01]

@TiTSxxMcGEE Yes :) everything will be alright forever if we don't listen the bad premonitions about Earth...our soul is WE TOGHETER and not WE INDIVIDUAL ...everything will be alright :)

[nehorlavazapalka]

3:19 EPIC FAIL!!!!!

[Ericmor]

Mmm... i knew Carl remade COSMOS for DVD... that explains the HUBBLE TELESCOPE images of Galaxyes on the video - the original COSMOS showed only artistical paintings of galaxyes :D

[taiko78]

Me might soot off the arm and, in say a biliion years have a different nearest star

[LucMoustache1]

i like it verry much , menny thanks for the explains Luc Clymans

[imthejman85]

Sagan say what!?! FUCK THAT CHAIR!

[ilikezelda64]

I get a strange feeling from watching this.

[LPF767]

Does anyone know what Cosmos episode this was from?

By far an excellent posting, thank you for doing so.

[VanKlaunch]

I'm a compilation of "star stuff", currently and temporarily assembled into a complex, organic machine, from which consciousness arises, named Van_Klaunch. Carl, thank you for saving my mind and soul. I am going to pursue astrophysics thanks to Carl :)

[poliser0]

where did he find that spacecraft?!

[macmacma]

carl says "fuck the chair, im sitting on the freekin bulkhead!"

[ericsbuds]

lol. Carl pronounces it Eh-pock, where as i would say EE-pock. oh well im sure he is right lol.

[LeiMagnus]

@ericsbuds

naa - i think it's a to-mah-to vs. to-may-to thing

[ericsbuds]

My favorite thing about the Milky Way, which I only discovered for myself recently, is the idea of the intevening matter between us and the center. Which is why we dont see a super bright center. Just blows my mind. At least I think thats right. The darkness which I used to perceive as PAST the galaxy, is WITHIN the galaxy.

[hippo11222]

RIP Carl Sagan.

[awefaislfdas]

Elegant truths, and exquisite interrelationships. Thank you Carl

[Annulable]

Mesmerizing.

[willyschoonover]

Carl explained why life is both precious and insignifigant.

[brandtaylor93]

and people don't believe there is intelligent life out there.

well it certainly out there but not on earth.

[Planetary0]

And somehow keyboard cat gets 3 million + views.... sigh.

[ThePipersNicks]

I know what you mean and you're right, but don't pick on keyboard cat. That thing is brilliant. I can picture Carl Sagan laughing at it.

I do get mad at the judge judy's, and bikini clad hotties eating bugs. Reality tv and Fox news. Etc. :D

[blaksin]

such an interesting man, thanks Carl

[opiates]

LOL something freaky about this video...

At about 6:55, when the galaxy spirals, I let my eyes go mildly out of focus and was looking at the center of it as the video went on and it kept spinning, and when it was done i looked around the room and what I was looking at (my hand, the chair, whatever) and they started spinning. Like being on acid.

[mohfoz77]

EXCELLENT.

CARL SAGAN is an inspiration.

[Q9R42]

An inspiration to say the least.

I've told alot of people about Carl Sagan since I first heard of him..

If only more people would watch it..

[keggerous]

imagine being on a planet around one of those stars flying through space.....carl sagan was the coolest :)

[Annulable]

We are on a planet around a star which is flying through space ;)

[keggerous]

i speak of the stars that get flung out from the galaxies.....no stars in the sky for them. only darkness.

[drmanyuka]

not only stars, planets flung out of their stars into the eternal darkness

[ericsbuds]

Positively :P

[dson144]

Its either that, or maybe it has more to do with the fact that everything is just so far away in our galaxy, that it's too dim to see.

[cawkanos]

"Like a bullet through a swarm of bees"....brilliant.

[SagansMoon]

Could you just imagine sitting on top of a mountain with a perfect night sky and Carl to explain it all?  Brilliant man...

[lifeisgummo]

Carl could read me the small print of a legal document and i'd be in awe of it. He could literally talk about anything.

[TomthatiscalledTom]

Centuries from now, Sagan will be remembered as one of the greatest minds of the latter 20th century, the same way we now regard the likes of Galileo, Kepler or Newton

[DrakeMagnum]

I never tire of Sagan.

[Peanutbutterbucket]

Agreed, but if I was going to pick someone to sing me a lulybye..

[HylianSpirit]

I love how he spoke.

[Airicks1]

lol when ever i hear Carl Sagan talk i think of Spock off Star Treck

[kciNJNadon]

Miss you Carl

[evilchimp69]

imagine having carl sagan for diner

[evilsinz]

...and a nice bottle of Chianti

sssslplsssplslp

[Racki123]

EATING HIM?

[mosquitobight]

Imagine a planet at the center of a galaxy evolving intelligent life, and that life discovering astronomy, just in time to realize their sun was heading for the central black hole. :-(

I guess they'd be cooked by the jets of radiation from the accretion disc long before they felt any other effects.

[stet1965]

Finally the Cosmos series from 1980 is available for free viewing on hulu - all episodes. This clip comes from episode 10 "The Edge of Forever". Click on the "TV" option and browse the Cs and there it is.

[kvan1917]

Watching this video makes all my dilemmas temporarily disappear...

[booste30]

You can also kind of think of spacetime as a fluid in comparison to matter.

[booste30]

I love the background music.

[the666drum]

this guy is a genius... i mean it  looks nerdy stuff.... but no ....i just loved the 4th dimentions.... and now this ^^

[ByronC900]

Thousand Years of Darkness and Pale Blue Dot are my two favorites.

I love Sagan!

[mistermuffin420]

have u read the dragons of eden? he makes u really appreciate ur brain

[Lanparth]

lmfao

[summersonset]

evilsinz, best comment I ever read on YT.

[shockfox7]

it appears that way lmao

[WashingMachine0]

evilsinz, you have just won the entire internet. Well done!

[evilsinz]

Thank you, Thank you all,

But I really can't take all the credit. I'd like to thank (because I don't have a choice) the previous events in the universe that determined the events of the present, destroying my freewill and ability to be anything other than so damn awesome.

Thank you causality, big bang, gravity, and all that stuff.. without you, none of this could be possible.

[booste30]

Your gratitude is not required for what is just. Whatever happened, happened.

[evilsinz]

Two astroids collided billions of years ago and then some other stuff happened that caused me to be grateful.. its a long story, but I didn't have a choice.

One of the perks to not having freewill is- you run around naked with a rubber glove on your head while yelling "I'm a squid!"... and its not your fault.

[booste30]

Whatever happened, happened and so here we are. Giving gratitude to your own existence is irrevelant to the reality of this seemingly infinite causality. Embrace it, instead.

[evilsinz]

Embrace it, you're right! These pants are coming off!! wooohoo!

I'm a squid! I'm a squid!

[TadRaunch]

@evilsinz he is such a showoff

[danthemanzizzle]

@evilsinz dont forget he took a day off at the end cause he was pooched

[eckels3000]

I concur...Sagan does rule.

[TheFinalCut2207]

"The Nitrogen in our DNA, the Calcium in our teeth, the Iron in our blood, the Carbon in our apple pies - all were made within the interior of a collapsing star - We are made of Starstuff".

The first time I ever heard it phrased that way really blew my mind. Cosmos, and the Varieties of Science, changed my perception of things forever.

Sagan, does infact RULE.

[AnnandoX]

Sagan rules

[Tanru2000]

What is the next bit!?! I want to know about large scale structures of the universe! Anyone got link to next bit?

[sneezesneeze1f]

I want to eat star stuff.

[flyingdiamond]

I had star stuff for dinner tonight, like you. Mine tasted like chicken...

[mrpossibilities]

We are all made of star stuff

[CruxAustralis]

It's a shame that Carl Sagan never got to find out more about dark matter and dark energy and about the discoveries of the Hubble Space Telescope.

And he is wrong about galaxies - all parts of a galaxy revolve at the same rate around the centre.

[airrocker001]

of a supermassive black hole

[astronomer85]

that's right. I thought it was interesting that the simulation at 3:10 showed the inside of the galaxy spinning faster than the inside.

Of course, the inside spinning faster than the outside does produce spiral arms, ASSUMING that the spiral arms were primordial, yet this would only allow spiral arms to be a temporary phenomenon - on the time scale of 10's of millions of years - not nearly long enough to explain the observance of spiral arms like we see them in the universe.

[TeslaSagan]

Carl you are the man. Almost 30 years on this & this still rocks.

[SamsungSyncMaster940]

How are we (humans) supposed toknow that??

[HoloMatter]

know what?

[SamsungSyncMaster940]

the galaxies will react like that...like fluids

[alanochanman]

some galaxies are similar to each other, but they are in different stages. with advanced mathematics, a few seconds of measured movement can show the path of an object

[danieleriskay]

Because on a massive scale, gravity behaves somewhat similar to the surface tension and other adhering forces in liquids.

[Salladsdressing]

Carl Sagans cosmos is like poetry

[MoparDRVR]

plz correct me if im wrong.. but from what i learned the end of this video is a bit out dated.. by the fact that i think they proved that the outside stars of the galaxy does not spiral any slower that those at the middle... think its relevant to black matter.. plz correct me so i can get my facts strait :D

[HoloMatter]

The Dark Matter you are talking about is MACHO Dark matter that causes stars in the outer rim of galaxies to spin faster than the inner stars at the core which goes against Kepler's third law of gravitation. MACHO stands for masssive compact halo objects, so called because MACHO dark matter exists in the galactic halo; the region that surrounds the galaxy. MACHO dark matter would make up planets,stars, even life out of Dark matter whic appears invisable to us but makes gravity waves.

[MoparDRVR]

Fucking A man.. that was beautiful thanks

[kamz16]

very interesting and calm video.

[intigfx]

the music is "Création du Monde" from the album 'Apocalypse des Animaux' by Vangelis.

[fvaletudo06]

Carl is always in some type of aw sum room, I want my house to look that innovative.

[Gazzar]

It would be great if he was still alive today and could do Cosmos Volume 2 or something to popularise all the recent discoveries, of which there are many.

[bandgeek5804]

WHY DOES IT END?!

Rhetorical question, just in case you couldn't tell.

[AlmightScoop]

simply awesome. The way he explains things is very accessible.

[eatmyshorts5]

What room is he in? I totally want to be in that room!

[3dcow]

no just a deep voice ...

[uglyguido]

Thats deep, makes you realize how improbable our existence is as a race let alone all the other life forms on this planet and how lucky we all are to be alive. Fuck War.

[exinferiz]

Everything is probable. It is our self-importance that makes us feel as if we are special or as an improbable thing. There are a lot more improbable things in the universe. Existence is perpetual neverending war.

[gdmiller5]

always loved the way he talks...loved cosmos as a kid

[KN0MADD]

I could watch Carl Sagan vids all day.

R.I.P.

[weteyemoon]

inconceivably immense,

beautifully trivializing

[Vazquez71]

Were soooo small; way beyond our imagination...

[mangog1]

The series and the man himself was excellent, and so was the music for this clip

[MishuTaste]

The people the built the set provided a chair for Dr. Sagan and he didn't use it!

[sappy09]

I mean i know that the button gives links to related things but why porn? just asking.

[sappy09]

Whats with the porn links? If you watch this in full screen theres a button next to the play/pause button that has porn vid. links.

[gfrancavilla]

interesting very interesting

[RMERDINGER]

this video put me to sleep!

[RantVideos]

you have a week mind. excersise by reading bigger words and technicol books than run dick run spot is chasing you in the video game.

[stephenetienne]

weak

[beflap1991]

damn, you suck, really, asshole.

[69330066]

That sort of behavior seems to happen from time to time among lifeforms that have less intelligence.

[tackzam7]

We are truly insignificant.

[kwolf002]

"The cosmic pond"... great quote

[phoenixshade3]

I get chills when I see this. "Cosmos" was the birth of my interest in science. At age 9, I watched every episode in its first run.

It is not an overstatement to say that this program shaped who I am today. Thank you, Carl Sagan.

[ChaseKittens]

It's the same for me, with his pale blue dot speech. He is the best kind of scientist, imo. Very philosophical and was always mindful of the beauty found in science and the universe (keeping the beauty of science to the forefront), and all of his science was kept in the bigger context of humanity.

[trueuniverse2100]

Hundreds of millions of years. The atoms of Carl Sagan will continue through interstellar space forever.

[magicplants211]

i love how carl sagan smoked pot

[tfctc]

I love how you would love Carl to smoke pot with you. But let's get real. We're talking about galaxies, NOT about your pot smoking habit or whatever other drugs you are on.

Kisses,

TFCTC

[araxar]

now that sagan is dead, ignorance will once again wander without question

[maurice]

... which comment exactly proves wrong his unreal optimism about people. Assuming most of the mob are far better than they are and could be convinced to get interested in science that still interests only a tiny minority, instead of football.

Does the ignorance that will wander, include the Hindu creation mythology about the universe being dreams of Brahma, that he spent half this episode of Cosmos admiring and calling half-true ?

[BoozyBeggar]

Not while we have Richard Dawkins, Neil Tyson and Daniel Dennett. Also you clearly have an American bias. The rest of the westernized world understands the things they're taught because their school systems aren't totally fubar.

[YeaWhiplash]

and u would know?

[YeaWhiplash]

what a nice vocab u have.r u 2 yrs old???

[aesrp]

I wouldn't want to correct him on vocabulary. When you, yourself, can't even type out words themselves...you're both wrong.

[YeaWhiplash]

Why does there always have to be a assface who puts his 2cents in when NO ONE CARES.AESRP,stfu.Your the kind of guy that butts in a conversation and no one listens to you.Got a name for guys like you,SMD-Small Dick Syndrom!!!!

[aesrp]

you spelled syndrome wrong, and it's an assface buddy. you're not doing much to shut me up when you don't understand basic english when, i'm assuming, it's your native language.

[BLOOKAKAKA]

Infact, you've both made pre-school errors in your grammar and spelling. Give each other arse to mouth now. Thank you.

[schaits]

whats an arse?

[stet1965]

I've been searching for this music for a long time but finally found it ...it's "Creation du monde" by Vangelis on the album "L' Apocalypse Des Animaux". It's about a 10 minute piece. Absolutely hypnotic -

[msmit118]

I hope he wasn't unique, or now that he's dead we are in so much trouble...

[mototubular]

Carl... Carl,... your speech is always with us, you inspired me.... RIP...

[alejandroperes]

jcpiano it´s rather simple if two galaxies are moving appart from one another the moving appart it´s only relative to those two galaxies so it means they will encounter other galaxies in their path and collide ofcourse there is also there is the speed matter

[jcpiano]

If all galaxies are moving away from each other, I don't understand how galaxies collide. One day Andrameda and Milky Way will collide I hear.

[phoenixshade3]

It's a question of scale. On very large scales (clusters and superclusters of galaxies), the general rule of expansion holds true. Superclusters are moving away from each other as the universe expands.

On a more local scale, however, gravity can overcome this expansion. Individual galaxies orbiting the cluster's center of mass can and do collide. This was much more common in the early history of the universe, when it was more dense.

[phoenixshade3]

This is seen in direct observation. When we look at distant galaxies, we are looking back in time. (The light takes billions of years to reach us.) The further away we look, the more frequently we observe galactic collisions.

[saganemc2]

i love carl

[USernamessuckbad]

Does anyone know the name of this music? Please post the title and artist!

[Earthlinked]

It is called "Creation du monde" by Vangelis on the album "L' Apocalypse Des Animaux".

[yaddayadda]

sagan will always be unique one of the most amazing people science will ever see

[icecorescientist]

thanx for posting!

Sagan was unique

[saganemc2]

"ice-core"?
