The Language Of Life

[Flusercom]

Good Video. Very Infomative..

[Spasatcom]

Cool, Good Video, Thanks for shared

[DarienVictoria]

@7:42 I knew it! Carl Was a vampire!

At least I don't feel so alone anymore...

[socomplete]

@ACspainDC Do you think because scientific terms sound complex , that believers in gods, just cannot comprehend why it doesn't, take a creator to form DNA?

[joergsattler]

we need more visionaries like Karl Sagan , and maybe we would not be in as much trouble as a race (human race) as we are

[Mu5clehead]

This is so beautiful.

[nicolanthon25]

i will not feed my future kids with information about heaven and hell, how god hates it when we sin, etc. i will feed them with these type of information. :D

[bttrflykiss7701]

So Frikin amazing...

[spamvigilante]

Nothing short of amazing. And for the idiot creationists who negatively rated this clip, please tell us why you think science should be outlawed. Keep sticking your heads in the sand. Hey, keep praying for a cure for Grandma's cancer instead of seeking a scientific cure. Wow, you are all stunningly and embarrassingly ignorant.

[TooMuchToo0ften]

lots left out the process but who could blame them this is 30 yeaqrs old

[LightningNC]

What was that orchestral piece starting at 3:39 and again at 7:25? I know I've heard it before....

[devourerofbabies]

This shit kicks the fuck out of ass!

[CAlex6977]

Ohhhh Pachelbel why do you keep following me.

[CipherSpectre]

I remember watching this as a little kid.

[MilletGtr]

So beautiful.. Love it so much!

Modern poetry

[thudmother]

Sagan is my hero.

[goldgoku3264]

funny, but Dna is an argument used for inteligient design.

Dna is a language, "ATGGTAGAATTAG"

ect.

the question is, did this complex information come about on its own?

if we can decode the information in Dna, who encoded it? i honestly don't see ANY naturalistic explanation of information giving rise by itself, and then operating on its own to create a human being.

[gavinplaysbass]

the difference between DNA and a human language or code is that the building blocks of DNA are chemically attracted to eachother. In otherwords, you wont find a book or poem congealing out of random words floating around, because words dont have any natural, chemical affinity for one another. But you will find self-replicating molecules forming out of sheer chemistry.

[goldgoku3264]

can u give me an example.

[gavinplaysbass]

Well a simple example would be that the hydrogen atom is attracted to the Oxygen atom. Without this attraction the water molecule wouldn't exist. The principle being that you don't need intelligence for complexity to arise out of simplicity due to the attractive nature of atoms. Laboratory experiments such as the famous Miller Urey experiment have succeeded in generating amino acids etc. out of simpler chemicals present in the early earth as well as other planets.

[goldgoku3264]

it amazes me that people use the miller experiment when the experiment actually did a diservice to hypothosis.

miller excluded oxygen from the experiment. yet what he created was right and left handed amino acids. yet this process HAS to be random and you'd have to have left only. furthermore do u know how complex 1 single cell is? amino acids are just the building blocks.the demonstrated that even with intelegence behind a so called naturalist cause. life is not that easily expalined.

[puncheex]

@goldgoku3264: No, you don't have to have all left-handed molecules. It may be that life develops to take advantage of only those; the existence of the other is simply ignored. No, a total explanation isn't easy; years of research have gone into it and will continue to be. Early cells would be very simple, unlike those here today.

Miller left oxygen out because the ancient atmosphere had none. Any free oxygen would have gone immediately to oxidize iron in the water and been locked up as rust.

[goldgoku3264]

donald brownlee wrote a book called rare earth. " why complex life is uncommon in the universe".

you made a statement " without this attraction the water molecule wouldn't exist."

my question is where did the laws for that attraction come from if a naturalistic explanation.

life it seems is rather fine tuned for life. AND we have universal laws.

the gravitational force, the weak and strong nuclear force, the electromagnetic force. how did these come about?

[gavinplaysbass]

I am fully aware of how complex a single cell is. What i'm saying is that the complexity built on itself from a simpler point. The reason Oxygen was excluded from those experiments is because the prebiotic earth apparently had little or no atmospheric oxygen. The plants life that arose was what put the oxygen in the atmosphere.

[gavinplaysbass]

To address your question about where the 4 forces came from: Simply put I don't know. What you are doing is describing the universal laws as if they were literally laws set forth by someone else. What they are are predictable ways in which matter and reality behave, we chose to call them laws. Just because the universe acts in predictable ways does not mean it had to be designed.

[goldgoku3264]

the thought that we can even comphrehend the external universe is a miracle itself.

have you ever seen the video the privilaged planet? its here on youtube.

in it, they explain the mathmatical odds of our planet with all it's laws, with all it's chimistry with all of its complexity to have came about by naturalistic explanations.

do you know what the odds are?

1 over the trillion trillionth gavinplay.

THAT is alot of zero's.

[gavinplaysbass]

The only reason this planet is so perfect for us is because we evolved to live on it. Planets don't conform to life, life conforms to planets. We could be two aliens in the methane oceans of titan right now having the exact same conversation because we only know of life as it is here. But we can see from various types of bacteria and deep sea life that organisms can thrive in a variety of places.

[goldgoku3264]

can bacterias thrive on other planets?

[gavinplaysbass]

Based on the fact that we've seen them live in poisonous sulpheric acid pools and we've seen them breathing arsenic and we've seen them living around above-boiling-temperature ocean vents spewing out poisonous chemicals, i say why not? Astrobiologists have speculated that both Mars and Titan could be home to these kinds of extreme-conditions bacteria, and by extension perhaps other things as well.

[JarradIRONEAGLE]

@goldgoku3264 Depends on bacteria and the planet, but we are finding bacteria entering from space in asteroids, most of them anaerobes, so the answer will be yes.

[Zskillit]

link? i think that would be some of the biggest news in the history of the planet. and as far as i know it has never happened. the one asteroid that came from Mars that everyone thought had a small fossilized bacteria on it, turns out that it wasn't. if you have proof, please share it. im not calling you out, im just genuinely interested.

[puncheex]

@Zskillit: Panspermia has been an idea that has been going around for a while. The problem is it only moves the creation of life back farther, into realms that we cannot even speculate about, so, like creationism, it cannot answer how life began, but unlike creationism, it is still a natural possibility. Google the term.

[devourerofbabies]

@JarradIRONEAGLE Bacteria entering on asteroids?  Link?

[puncheex]

@devourerofbabies: Google "panspermia". See my comment below.

[WOWJBEOWULF]

@gavinplaysbass If we find something swimming in Saturn, as it has a strange north pole structure, it would be a miracle. The premise of DNA is feed a mix of chemistry enough energy under the correct conditions; then the random actions of chemicals eventually creates life at the DNA, simply organizing, and the survivors are the parts of life that organized the best feeding on the less capable. No right path, humans must have been terrorized, until we made our first tools, we only have brains.

[gavinplaysbass]

@WOWJBEOWULF

For sure, i definitely agree there are likely some constraints on likely places for our type of complex chemistry to form... My point was just to point out the backwards reasoning in the design argument.

[BoxOWater]

so much fail :(

[paw965]

I never realized how much Sagan sounds like Hugo Weaving's Mr. Smith character from the "Matrix" movies.

All this structure and purpose and no God for Mr. Sagan. Pity.

[hsantos20091]

Hi. Im from brazil... Someone speak with me

[viewtiful12345]

Now this is why life it is beautiful....

[deefsound]

I assume this video was vote-botted. Because three stars for this beautiful slice of science narrated by one of the most inspiring individuals in science is just plain weird.

Absolutely fantastic stuff!!

[y2knoproblem]

So one rouge enzyme could potentially unhinge all life on earth?

[RodHullIOnceWasHim]

Makes you want to pat yourself on the knee (but bnot too hard) and say "Good work Guys"... :)

[MaDrung]

So when the wrong part is built in the DNA (mutation) it changes how that cell reproduces and that makes cancer?

So if I get a blood from someone else I will start developing partialy by his code? confused here... :/

[320iguy]

No the mutation only comes from the creation of NEW DNA strands during reproduction (birth) process. there isn't any mutations during the replication process cell division.

[DarkAngelGuyver]

Nope, your blood is actually produced from bone marrow. When you get a transfusion it only supplements things when your body can't produce enough blood to make up for what was lost.

To change "you" would require changing the DNA sequence in the cells in your bones and even then that only goes so far. As for cancer, everyone has cells that develop poorly from quirks and genetic damage, just normally it doesn't spiral out of control and is quickly cleaned up :)

[Shalek]

Blood cells don't reproduce, they are made by the bone marrow, if you recieved a bone marrow from someone else then yes, some of you blood cells would differ in genetic material.

[Shalek]

recieved bone marrow*

some of your*

[MTAJ78]

Sagan is just the greatest. If you want to read another fantastic description of a cell pick up "A Short History of Nearly Everything" by Bill Bryson. Apparently each strand of DNA, if unwound, would be about 2metres long!! (annoying, because that's taller than me...!) One of the best science books ever written.

[deefsound]

Yeah, it's a great book isn't it. I've read it twice and loved it both times.

On the subject of books I heartily recommend A Briefer History of Time.

It's a great update to Hawking's seminal work.

[satansaysdie]

Just to let everyone watching know, scientists have now synthesized RNA with basic abundant chemicals. Actual RNA not just nucleotides and bases. This "stuff" they made it out of is detectable in comets meteors etc. I.E. In space where we live. Woot. All it took was evaporation and condensation of the water the chemicals were in. Very basic fundamentally occurring type stuff.

[luckystrke]

Insta-favorite. :)

[purplejugnut]

i just decided to click on the ad as many times as i can while watching this video. i hope the advertiser pays by the view/click.

[DeemotheAtheist]

seeing phagocytes at work is amazing

[abyssquick]

Yeah that "atheists' riddle" AD is unwarranted.

[fatmanprime]

My firefox has an addon that stops all ads from loading, so i can't even see it.

[MilletGtr]

Awesome.. Thank you for uploading this

[abigor315]

sagan was such a great dude! what pisses me off that there are adds for "the atheist riddle" with his face on it...

[Shigren]

are you serious? That angers me. Carl Sagan was a brilliant man and he would never stamp his face on such broken logic.

[abigor315]

yes its on the right of videos... makes me RAGE.

[BananaHurricane]

Agreed. I wasn't sure if I was the only one seeing it.

[abigor315]

sent a pm to saganappriciation group here on youtube, hopefuly they can foward it to someone more powerful or even they themselfs, could make some progress in removing it...
