Carl Sagan's "Cosmos"

[raoulhery]

what are the flat business he is talking about

[BananaOverlord]

@raoulhery It is based on a book called "Flatland" written by Edwin Abbott Abbott. It is very interesting, I suggest you look into it.

[xXxEL1TExXx]

[hellysonmanaus]

God will come to judge who doesn't believe in Him.

I believe and Jesus is my savior.

[borastro]

I can not belive he ruined a perfectly good apple

[Mustamaggara]

my brain is full of billions and billions of fuck.

[msapplesass]

It is not a 'flaw' that he does not explain what would happen to the Flatlander if he were to visit the third dimension, as "Flatland" is not Carl Sagan's book. It is Edwin A. Abbott's book of which Sagan is speaking. He is simply using the concept of Flatland and the difficulty that the Sphere character has describing himself to the character A. Square to help explain the difficulty in helping us to comprehend the idea of a fourth dimension.

[rico343343]

@humbertojimmy he wouldn't feel "strange" if thats how he spent his entire life. Even if there was an "extension" that we could feel but couldn't observe we would be used to quickly and probably eventually forget about it.

[humbertojimmy]

There's a flaw... Carl never explains what would happen if the Flatlander visited the 3D world. Would he find out he was also a 3D entity or, instead, would he be a lesser flat shape still? If he was a 3D being, then he should have spent all his life feeling "strange", with extra room within himself beyond what he could see and he couldn't have 0 height cause that's a paradox in a 3D reality. If we lived in a hyperdimension, we should feel an odd "extention" of ourselves that we couln't observe.

[kinglito93]

Thumbs if you are watching this because you had to read "FlatLand", and write a report on it!

[finalfrontier001]

thank you carl sagan for proven religious facts and unknown dimensions that god only knows

[Quartrez]

@finalfrontier001 lol you're funny

[Quartrez]

@finalfrontier001 Those dimensions (or THAT dimension, for that matter) is not unknown to us. If it was, we wouldn't know about Tesseracts. If you understood how the hypercube worked and why its 3D shadow is the way it is, you would understand how out-of-topic your comment is. The fourth dimension has got nothing to do with a god.

[finalfrontier001]

thank you carl sagan for proven religious facts

[matthewjamal]

im 20 and i feel like im being told a bedtime story. lol i love this guy

[Rocinantex1]

Reminds me of Agent Smith...

This is a cube.... Mr anderson......

[websharky2k]

"Professor X" looks fucking baked in this video. My money says 90% of people have NO idea what I'm talking about haha.

[nbrothergtr]

that square barely fit in the door

[StrikaAmaru]

@nbrothergtr It's an overweight square; let's not pick on it.

[hellonearth1066]

It's agent Smith...

[jonc172]

If the square was taken out of 2 dimension into the third dimension, the square would not be able to look "down" on flat land since the square has "evolved" only to look in 2 dimension and would only be able to see a cross section of 3rd dimension, much like the square could only see a cross section of the apple.

[FluffyBunniesOnFire]

We now return to Carl Sagan's Cosmos [Edited for Rednecks]:

I'm Carl Sagan. Just how old is our planet? Scientists believe it's four bi-[Hundreds and hundreds of years old].

Scientists have determined that the universe was created by a [GOOOOOOOOOOD]-ig bang.

If you look at the bones of a [Jesus]-saurus Rex, it's clear by the use of carbon dating th-[Mountain Dew is the best soda ever made].

[gersane]

@FluffyBunniesOnFire That's funny :-DDD

[KIMBOSLICE66666]

@FluffyBunniesOnFire screw you ...Dr. pepper is better

[FeelTheSexualTension]

I have no idea why, but this video seems hilarious to me. x3 I mean, Sagan is absolutely right, and this explanation is brilliant-- but his voice tone and his style of enunciation is so very... different. It's the type of voice I'd expect in a cartoon.

[Justas923]

He perfectly explained: We cant understand 4th dimension

[haznick]

Why does he sound like Reverend Lovejoy off The Simpsons?

[jimbobeire]

Rev. Lovejoy has a jaded voice, reflecting how tired and cynical he has become. Sagan does not sound like that, but he does have a very distinctive voice.

[zaitesushion]

I want to do some flat business with Carl. ;D

[hurley3kgt]

So, based off of this concept, everything that we see is just a shadow of the 4th dimension?

Secondly, What have we viewed/looked at where we have seen a "miraculous" imprint out of no where like the apple's imprint on the 2D figures in Sagan's example that would be indicative of 4D activity popping up out of no where in our 3D world as imprints? Just thinking! Love doing it!

[r4v3nh34rt]

lol that's the whole point man.

[URProductions]

The 4th dimension is Time. Therefore your 5 year old self, 16 year old self and 40 year old self are merely 3D cross sections of your entire 4D being.

[JordanMedina]

@URProductions-- Don't be confused with the idea of the dimension of time, popularly known by the layman as the 4th dimension; this discussion is about the 4th spatial dimension, or if you want to you can call it the 5th dimension.

[URProductions]

Let's not quibble. It's just I think the flow of time is the best real world example we got of higher dimensional cross sections. Maybe the only example, really.

[JordanMedina]

If you think about it, our perception of "time" is just the flow of order to disorder; the thermodynamic, psychological, and cosmological arrows of time. I don't see how these things are a real world example of anything Sagan or Edwin Abbot are explaining.

[URProductions]

Eisntein stated explicitly that time is a dimension the same as length width and depth. That space and time aren't really seperate but part of the same continuum. We KNOW the three spatial dimensions exist and we understand pretty damn well that time is a dimension perpindicular to the three dimensions of space. Any other dimension is unproven and purely in the realm of speculation.

[Russe11john]

@URProductions this is how i view it. time, matter, and energy are all are in sync with eachother. the 1st and 2nd dimensions are representations of an infinite that can't be achieved. the 4th dimension would be a figure beyond infinite, but in an opposite direction. i would'nt call time a dimension or say past and future are those directions. time is only a measurment and the idea of future and past dont exist when your looking at them from a prespective thats infinitly undetermined

[hennishx]

@Russe11john

wat

[syngar99]

@hurley3kgt no, actually what sagan said was that we can not perceive the 4th dimension and the shadow was the best way he could illustrate it. he wasn;t representing the 4th dimension he was representing the shadoweof the 4th dimension, so even further away than just a shadow.

[fuunguus]

@hurley3kgt If you see a object that twist in on itself then you better run cause he gonna get mad at you if you don't understand him and he is gonna throw you in the 4th dimension where you suddenly gonna have gaping holes in you, and intestines and brain is gonna splatter everywhere.

[KrypticAsylum]

Dude... I wish Carl Sagan was a professor at my uni...

[ramanglass544]

11 dimensions.....bitch

[EyedHitIt]

Just because we have labeled things length, width and height does not mean there is necessarily a 4th measurement, does it?

[zaaz369]

can't believe that he explained the 4th dimension in 6mins. Sagan's the master.

[stanisbell]

Elementary. Sagan is just now conceiving what Jesus became after the "knowledge busters" killed him. Jesus appeared within the locked room of his disciples and ascended 40 days after his resurrection to the 4th dimension and beyond. No man has any right to set up his own ignorance as the limit of what God has revealed.

[fearzone2000]

He explain it, but not well.... because he is just guessing... he did not prove anything.

[BaileysBeads]

He didn't intend to prove it, he meant to explain it, which is quite an achievement in the first place.

Einstein however, did a good job at demonstrating how gravity works interdimensional, by curving space-time.

Still not proof, proof only happens in maths. Science works with evidence.

[anthony68drake]

Ha ha, while we cannot "imagine" the world of 4 dimensions, we can "think about it perfectly well". Another great Saganism.

[randy95023]

I haven't smoked weed since the 70's, but when I did I would think about stuff like this...

Thanks Carl!

[PFWoody488]

First I read the Bible.

Then I saw Cosmos on PBS.

Then I read the book, Cosmos.

All three in combination lead me to abandon my childish belief in a magical sky daddy.

Thank you Mr Sagan.

You introduced me to reality.

[B3Sirius]

PF

I completely agree!

I did the same thing!

[segmemtum]

PF

THis could account for god. If god is in the 4th dimension, that would explain why we cant see him, or touch him. That would also explain why religious people hear gods voice from the inside.

whats your thought?

[PFWoody488]

segmentum:

"that would explain why we can't see him or touch him."

You could also explain this by saying 'he' doesn't exist as you already do for every other god. Also for unicorns, ogres, elves.... In short for everything that has absolutely no evidence to support the assumption of it's existence. This explanation doesn't require any attempt to find hiding places for supernatural beings.

When I am shown evidence, then I will believe.

[segmemtum]

PF:

Im not trying to convert as I am not a believer. You are probably right. No evidence of a creator.

[lelia72]

that is the BEST description of God I have EVER HEARD!!!

[segmemtum]

Irony???

ANyway I dont believe in a god, and thats why I dont understnad people have downvoted my comments.

Seems nowadays people have the sense of atheists vs theists. I am just philosofying.

[muertos06]

A youtuber by the name of UNFFwildcard has made a series using this very clip of flatland to explain a little about natural theology. You should check it.

[segmemtum]

maybe I will. But you might as well put elves, lepircons and whatnot in the 4th dimension, and claim they existed. so It boils down to no evidence at all.

[muertos06]

I suppose a person could adhere to a layman's understanding, and make that insinuation.

Perhaps if a philosopher could make the argument that natural theology regresses back to, and reveals that what Leibniz was referring to as the PSR, is indeed elves, unicorns, etc... then maybe I'll concede that point.

But ultimately, a person is merely using a different name, for what logically follows as the supreme contingency of things. Especially for empiricism's reliability.

[segmemtum]

no, its not certain that ONE supreme being exists in the 4th dimension. there exist numerous religions which has several gods.

also it still has to be proven that a god exists in the 4th dimension and even that the dimension exists.

[muertos06]

So you're merely extending your first comment into your second? Okay.

Then I won't reply with any more references to philosophy, if they are simply going to be conveniently ignored.

[segmemtum]

Im not that good at english so please elaborate your references, and what was your point?

[segmemtum]

what is, PSR and who is leibniz?

[muertos06]

PSR is the acronym for the Principle of Sufficient Reason.

Gottfried Leibniz was a renowned philosopher, who's name is among the serious collection of prestigious historical figures in the field/discipline of philosophy, such as Hume, Descartes, Kant, Kierkegaard, etc...

To turn our backs on such people is laughable.

I made several points actually, and it is rather hard to break down higher-level advanced studies into simple English words. Sorry.

[segmemtum]

yes it indeed is. Also PSR is not an acronym, becasue you cant say it. NATO is an acronym for example but nevermind that.

can you try to elaborate your points?

Because what I can make of it, is that elves, unicorns can not account for theology?

Im guessing im wrong.

[FeelTheSexualTension]

@PFWoody488 Wow, it took only two books and a movie to shatter your entire faith base? That's incredibly depressing, actually.

[PFWoody488]

@SexTens:

1-Since one of the two books was the Bible, the basis for the so called 'faith base', it should be neither surprising nor depressing.

2-The "lead me to" in my comment does not imply a an instant on/off switch for my mystical beliefs. As with most people who manage to overcome childhood religious indoctrination, my awakening to reality was a gradual process that involved time and an effort at using my mind instead of relying on 'faith' (not thinking).

Faith/gullibility are depressing.

[FeelTheSexualTension]

I would hope it was that gradual.

My comment was less about how quickly you dropped your beliefs and more about how little it took. Though, based on how you talk about your previous faith, it wasn't that strong to begin with.

But you're right in that it shouldn't be surprising. More and more people are renouncing their religions these days--that's the depressing thing. Honestly, I'd give a lot to be able to have that sort of belief system, but it's probably just the grass-is-greener syndrome.

[PFWoody488]

@SexTens:

Abandoning mythological thinking in favor of reason and logic is not something to be depressed about.

For me, the depressing thing is that so many people still waste their lives believing in such obvious nonsense as magical invisible beings. I prefer to think for myself as opposed to accepting the nonsensical, self serving ramblings of so called 'holy men'.

The grass really is nice and green over here in reality. I hope that you can join us someday, but believe whatever you want.

Bye

[FeelTheSexualTension]

I'm already where you are, unfortunately. And it seems awfully depressing to me. Religious people, when they lose absolutely everything, can at least cling to the fact that there's a reason for all of it and that there really is somebody out there that cares for them. Atheists (like you, I'm guessing) and agnostics (like me) have nothing to hold onto.

When our lives are fine, it doesn't matter whether there's a god or not. But when our lives are terrible, I bet it would be nice to believe it.

[rkyeun]

@FeelTheSexualTension

Well, we don't actually lose anything there. Atheists still have the option to sit with their hands folded talking to empty sky instead of doing something that might help their current situation. Most of us just realize the latter is a better option.

[syngar99]

@PFWoody488 for me the depressing part is seeing barely educated people lecture and insult others because they still believe in god.

what is the purpose of enlightenement, if all you do with your "greater" knowledge is insult people.

i am an athiest myself, but i am smart enough to know walking around calling religious people stupid only leads to hate and bad feelings, if you can't educate without being condescending, you are certainly no better than the worst fundamentalist.

[PFWoody488]

@syngar99

#1- If you read my comment, you might notice that the only beliefs I refer to are my own. I lectured no one. I insulted no one. If you choose to read more into it, that's on you, not me.

#2- Thanks for the insults in your lecture/response. I love irony.

[syngar99]

@syngar99 you make the false conclusion that shooting a murderer is the same thing as being a murderer.

you DID insult and lecture, though a bit on the passive aggresive side, you DID assert that believing in god was believing in mythology and you did assert your own (self proclaimed i might add) superiority. Do you think because you did not outright call theists idiots, that it absolves you fromb eing held accountable for insulting?

[URProductions]

peas and carrots.

[syngar99]

@PFWoody488 childish is assuming that god could only be a "magical sky daddy"

the inability to recognize the complexity , breadth and width of the universe is beyond some internet trolls capabilities to understand

[alcabanzo]

I did exactly the same thing...

[Thycid]

@PFWoody488 And then you read the Qu'ran, and realize it talks about many things that are in Cosmos, and you become a Muslim, a religion that is appreciative of science.

[Rocinantex1]

@Thycid

....or the religion of hate, which is what it is.

[Rocinantex1]

@Thycid

It's not really even a religion, it's political. If it were a "religion", it'd be accurately deemed the "religion of hate"

[Thycid]

@Rocinantex1 1.5 billion people disagree with you...

[Flyboys243]

@PFWoody488 either sarcasm? or totally retarted. wow dude :(

[syngar99]

@PFWoody488 it seems it also led you to a pretentious condescending attitude towards those with differing beliefs.

bear in mind i AM an atheist myself, i just cant stand all the self congratulatory snark from people that are usually not much -if at all- brighter than theists.

[PFWoody488]

@syngar99 So you didn't like my comment, huh?

Oh well.

Since your snarky opinion is ever so important to me, I guess I will just have to try to find some way to carry on despite the crushing weight of your disapproval.

Oh woe is me. : ]

[beefypotato]

I'm loving that chair. I wish I had one like that.

[RevStaplehurst]

I can remember watching some of this when I was a kid...

Shame there isn't stuff like this around now

[spike0804]

yeah...you really can't imagine it....

you can think of somethign like this though..

imagine your in the 2nd dimension....only can move up or down and forward or backward.....if there is a blockage...you can't get passed...

however..in the 3rd dimensions...you simply can move left or right to get around it....

now...if you have a wall in front of you in the 3rd dimension...you can't get around it....similar to above however...in the 4th dimension...there is a way around, "through" the wall

[livenlearnathome]

Doesn't he remind you of Agent Smith from Matrix?

[YodelRock]

TAHT WAS INCREDIBLE!! THSI GUY IS BRILLIANT! I WATCHED THE WHOLE THING!

and lol hes funny at times too lol haha

[ripelivejam]

he was- well, still is- my hero. able to instill wonder while still championing rational thought at the dearth of pseudoscience. a true inspiration like no other in my youth. he will be sorely missed.

[ZoomBFX]

shit too deep for me

[kablamo9999]

If flatland has no height, then how can there be a crossection when a 3D object goes through it?

[Idiedintothe]

It's an analogy.

[collapseofthedollar]

for anyone whos seen imagineing the tenth dimension, you can see why this is a much, much better comparison

[medic007]

I've always found it amusing that, as in a 2D world a 3D object can move through walls (by using the Z axis) that a 4D object in our space could do the same.

[pxhidalgo]

I have always thought at the fourth dimmension something like the "time dimension"

start with a dot

1 dim is a series of dots (line)

2 dim is a series lines (square or shapes)

3 dim is a series of shapes (apple or object)

4 dim is series of objects in differrent consecutive places (time) that is the same apple moving accross the room, every instance of time is a three dim. So if you could go to the fourth dim, you could travel in time, im not a physicist, does it make sense?

[devonherrington]

UFOs, aliens, and Astrology, Carl Sagan can debunk anything, and with a remarkable flair for language.

He would be every little child's idol forever.

[Erech01]

too true;) Shame he is dead:( he would have been extatic at the possibility of life on mars from recent discoveries, its almost a crime that he's not alive to witness that:/

[celsius233]

Trippy

[jmfmauricio]

i have a theory of my own:

The fourth dimension is time, not as we know it but as a dimension in which you can travel. being, you could go back and foward in time as you can travel back an foward and up and down in three dimensions

[l00zekk]

yeah i've seen that in "back to the future".

[Yttrium77]

Shouldn't the 0th (or "Zero-ith") dimension be time instead of the "Fourth"? Even if something is a point mass, it should still travel through time.

I say this since the dimensions are ranked: if something is 2-dimensional, it has the ability move in a one-dimensional fashion (x-only) as well. If it is 3-dimensional, it can move in a 2-dimensional fashion (x and y) similarly.

So if something is even only one-dimensional, it also can move through the most basic dimension, which is time.

[CA2BECKER]

And then we could travel in a fourth dimension of space in a way that time doesnt exist Which also could explain the origin of our three dimensional universe

[CA2BECKER]

You can figure it by thinking in Sagans 2 dim world Time exist in this world What happens if we go to the 3rd dim. If we move in a 2 dim nothing but if we move up and down maybe time w'd be different

[CA2BECKER]

Think in an airplane. As we move it seam we go very slow. Our perception of time is different than it is on earth As we can perceive the time of landing Time seams to move faster and we notice the speed of the plane If we could move in a fourth dimensio we could then expect a difference too.

[EyedHitIt]

never heard that one before

[nizzmarshal]

why a tesseract i would rather say a cube is a result of a forth-dimensional shape but hey i disagree with this theory , as i can define one line as one dimension, 2 orthogonal lines (2dimensions) , 3ortho lines (x y z) 3dimension , you can't make four orthogonal lines otherwise you'll be back to 3dimension.

the fourth dimension doesn't exist geometrically

[awhislyle]

"i can define one line as one dimension, 2 orthogonal lines (2dimensions) , 3ortho lines (x y z) 3dimension , you can't make four orthogonal lines otherwise you'll be back to 3dimension.

the fourth dimension doesn't exist geometrically"

Did you watch the video at all, or are you completely daft, you missed every point made in the video. The point of the video is that just because we can't observe the fourth physical dimension doesn't mean it doesn't exist.

[BigT69694321]

he reminds me of agent smith from the matrix lol

[Simlets69]

oh and also saying Carl Sagan, rest in peace (RIP) notates that he was religiouse when he was infact athiest, RIP is religiouse origionaly rest being what the bible discribes fir when we die.

[Simlets69]

Ps: read my first comment first.

[Simlets69]

able to understand or comprehend anything close to his exsistance or where he exsists even with the use of more than 10% of our brains, becouse i tend to think he exsists in a way that can only be explained by saying he is somewhere inbetween exisisting and not exsisting.

[Simlets69]

(Anthony) but then that would have to be a dimention created, and their for a place for god to exsist in, but then where did he exist before that having been always exsisting as such. and humans suposedly being a creation of god, we would never be

[anthony68drake]

What's interesting is that Carl Sagan, the eternal athiest, (pardon the oxymoron) could be describing spiritualism in this presentation. The coming of Jesus and our confusion about the dimension of time from which he comes? Out of body experiences? God's knowledge of the future based on his existence in another unknown dimension ("getting into another dimension, provides as an incidental benefit a kind of x-ray vision").

[princedime11]

man shut up

[garouHH]

I seriously have no idea how to relate to your comment. Either you're one of these guys who grasp at every straw to get a justification for scripture from science, or you're a far-out new ager and I'm nearly too afraid to ask what ideas about how to flip human consciousness. Ór you're a rather science-oriented guy who'd tell himself "Okay, let's see if the 4D-guys show up again for a picture.".

Or you're really a physicist and see reality as an n-dimensional mathematical expressions anyways.

[anthony68drake]

Whew, man, had to watch that last part a few times to get my mind around it.

[wyrwich]

i suggest not watching this on drugs. I scream my ass off

[exhoicat]

Wonderful! A suggestion: If you haven't read Robert A. Heinlein's story, "And He Built a Crooked House," DO! The house is a tesseract.

[mazdaplz]

i have a copy of the book FLATLAND it is awesome really well sumarized by carl, but sagan's insight on time is priceless

[Rittoshi]

Wow.. Thanks for upload this video, I always wanted to watch it again.. when I was little I watched on Tv. and I was so amazed about this It really changed my perspective about how we look to the world.. always wanted to see it again.. Thank you so much.
