- If life exists elsewhere in the Universe, would we be able to communicate with it? In this clip from the 1977 CHRISTMAS LECTURES "The planets", Carl Sagan demonstrates how we could send a signal that would make sense to intelligent beings that have evolved independently from us.

This is why Carl Sagan was so unique, he could explain complicated matters in a way that kids were able to understand, but at the same time it makes me amazed as an adult
are you sure that kids understood?
@@rolomovement9811 lol a few kids understood.
Most were bored and had no concept of what was being said. ... Ironically exactly like most adults navigating society today :(
Andrew: possibly the bored kids in the vid actually ARE the adults of today to whom you refer...
@Oskars Lielmanis I'm 12 and I understood.
he chose topics that COULD be explained to 12 year old kids lol. You simply can't explain actually complicated ideas, like the fundamental theorem of calculus, using pictures and slides.
A student tracked this down for me - I was one of the graduate students. What this video doesn't show is that we had 48 hours to decode the message (or fail), and be recorded after the fact by the BBC, whatever the outcome. Failure was not an option, but success wasn't guaranteed - what was fun was that each grad student made a separate contribution (although I confess that I'm not sure that my insights were that profound, or that if we reassembled now we'd be able to do it again!
You guys still did great. Not sure I could have done it! Also, what an honor to study under such a legend!
Nostalgia....
Formaldehyde: So the molecules have a particular radio frequency and that's the frequency we should use. What is the source of this information?
@@AdeelKhan1 I think it wasn't much before this event that astronomers had detected the presence of formadelhyde in interstellar clouds in our galaxy - every molecule has its own 'fingerprint' of frequencies of that it can absorb or emit, and from measurements on Earth in laboratories the radio frequency of formaldehyde had been measured. This made it possible to identify this rather simple molecule as having been produced in abundance in clouds of gas and dust in the Milky Way. The idea was that the signal we had decoded had been sent at LOTS of different frequencies, but at a very slow rate so that it was easy to detect and decode. It was like a billboard on the highway saying 'tune your radio dial to WQXR to hear the latest news.' The recipient would then know where to listen for the real message that would contain much more information. One of the challenges of this kind of imagined alien communication is figuring out where to tune your radio dial, and this was an ingenious solution.
@@richardgfrench5357 Formaldehyde appears to be a precursor to amino acids as the foundational building block of life. I see, so you are saying that it absorbs or emits a certain radio frequency. So it's a precursor channel, which if were an alien signal, is a suggestion to tune into a particular frequency. Because there are indeed be many frequencies. If I understood correctly. So we are talking about a precursor signal.
Carl Sagan was the biggest influence in my life. I had hope back then. Wow... How I miss this great man...
He seemed to have died very young!
@@Dyslexic-Artist-Theory-on-Time Yes, he was only 62.
His legacy remains.
Hope dies last. Hope you're doing well all these years later.
Alien 1: huh its a formaldehyde molecule
Alien 2: I think they want us to preserve their species once they are all dead.
😂
"Beep BEEP beep beep BEEP!" -- Carl Sagan, 1977
D Q contact...........prime numbers......?
He was singing 3 frequencies, not 2. I just have to take advantage of an opportunity to correct him.
Finally I have discovered who composed the track Mr Krabs requested!
That's a LOT of swears in one sentence, Dr Sagan! @.@
Beep beep bop bop boop - mr krabs
Living in Ithaca from 1972 until 1984 I had the distinctly awesome pleasure to listen to this gentleman lecture us a Cornell in person, numerous times.
At risk of sounding like the previous comments, Mr. Sagan became one of the most influential in my life and one I hold in highest regard. I seriously miss his influence on our world.
unlike his physical body, Carl Sagan's influence on our world lasts as long as we care to preserve it.
@@busTedOaS true today it's ag great need for humans all around earrh
So true for me…….heartbreaking he’s gone
Carl Sagan really is the best
And is book Cosmos!!!
CybranM the way he educates paved the way for the likes of Tyson, Greene, and many other personalities who now do it well like Sagan did
He was my advisor. I owe him a lot.
Tell us more
I could listen to Sagan speak for hours. Great speaker, story teller and lecturer!
Wish he was still around
He's in Sagittarius A
Maybe he is here and you just don’t know it 😉.
Mee too
Those bored grade schoolers didn't know what they had in front of them.
Especially the one in the brown shirt. lol
dude even the Sagan's students had a hard time tryin to figuring out what this thing was, I think you're expecting too much for the grade schoolers lol
Alejandro Betancourt - he’s a legend
@David Lamb why the hate bruhh? Carl was a star man, a curios one that was highly evolved as a human being.
@@lumigg2556 He wasn’t asking the grade school children to decipher it; he was showing them how his grad students figured it out. It was a demonstration of one method of communicating with an extraterrestrial species. Humans have trouble communicating with each other, especially with language barriers, even though ultimately virtually all human languages are related to each other.
The problem is how does one communicate (using radio waves, a form of light, and thus traveling at the speed of light) with alien beings, who would obviously not understand ANY human language. Sagan was involved in the design of the plaque on the Pioneer Probes, and the record on the Voyager Probes, which are headed out of our Solar System forever, and may, deep into the future, be picked up by some interstellar aliens. How would one communicate with them? So Sagan has had a lot of opportunity to examine this question. And the scheme developed for his grad students was used in his novel, “Contact”. (The movie is good, the book, even better.)
Cheer up, folks! Carl Sagan still IS a great influence on many, and he STILL inspires a lot of people to continue his work. That's why he smiles in most pictures... ;o)
True and the search for an objective understanding goes on!!!
I love how years later we see this exact example of first contact used in his book/movie Contact ,.,.
I was thinking the same thing. What a treat to see the experiment unfold and how it influenced his novel and the film. What a genius. So clear in his thinking. I can only marvel.
Wow I’m not alone on this one
Look at all these young children getting educated on such an adult matter. It' s really nice to see.
Well to be honest , most of them looked like they'd rather be sniffing glue than be there.
Lmfao
They were miserable. Such a waste.
Happens every year at the RI Christmas Lectures, they're great
These Christmas lectures were televised on the BBC at the time. I used to watch them every year, although I am slightly too young to have seen Carl Sagan's lectures. It's been something of a pleasure to discover all the old lectures, and those in the intervening decades.
Carl Sagan is responsible of me becoming a scientist. Profoundly in dept.
Bruh... profoundly in department? Do you mean debt?
Shoulda taken a language class first.
positron underVolt , game point
He's also responsible for Hugo Weavings rendition of the agent Smith character from The Matrix.
Ryan Peters I want this to be true and so I must pull from my reserves of skepticism. ❤️
Carl Sagan = one of the greatest brains of the 20th century.
2:07 He was forced to come to this lecture and would rather be watching the football.
Carl Sagan is the legend which lives on for ever in our minds... Love from India
Carl Sagan is still a great influencer, recently i read his book "A pale blue dot" and he inspired me to study astronomy and Physics, what a Great man!
Aliens: Why are they sending us message of Mickey Mouse?
Also Aliens: Tune into Looney Tunes and spend decades trying to decipher it
“Either way we win”... wise words Carl.
We will always miss this amazing Soul. He not only had tremendous knowledge & an analytical mind but also the power to deliver in his mesmerising talks on the universe. It was as if he took you on a journey. God Bless his departed soul. There will never be another like him. ✊✊✊✊✊
Carl Sagan is responsible for making me fall in love with astronomy
Carl Sagan was one of the most eloquent persons ever, gifted with an uncanny ability to articulate most complex ideas and deliver with such ease that a 9 year old me could understand. Love you, dear Carl.
I love the archive's video serie!
They are the best!!!
I love this series. Keep em coming
😂👍
I could listen to Carl Sagan speak all day long, everyday.
We need Carl Sagan today more than ever to counter the war on science
There is no war on science. There is a battle against biased prejudiced corrupt science which we can see in the covid19 scam and the climate scare scam. Follow the money and you find out that those people who want to shove that so called science in our throats are the same people making billions of dollars by doing so. Science has become corrupt. In the covid19 scamdemic and in the climate scare scam real scientists have been silenced, deplatformed, demomnized and fired from their jobs. Carl Sagan is turning around in his grave
I think Richard Dawkins, Noam Chomsky, Margaret Geller, Alan Guth, Neil Degrasse Tyson, Jane Goodall, Peter Higgs etc etc...are all doing just fine in Sagan's absence.
Carl Sagan. The best of the best. Not nearly enough people like him today. A great communicater.
stephen hawking
Carl Sagan, for sure, one of my heroes of the 20th (and 21st) century
2:07 .... I can't believe I'm missing Scooby Doo for this...
xD
I love his voice
I wish I had Mr. Sagan as a professor.
The quality of this is amazing for a Sagan video.
Still amazed by his approach to teaching n explaining!!
Carl Sagan is not a national treasure, he was a treasure of humanity.
It is a pity he is gone, My dad enjoyed astronomy astronomy programs watching Carl Sagan's programs when i was growing in teen years and I enjoyed watching with him. Good quality of programs of they day you don't get this today quality.
Carl was an inspiration
I absolutely adore his voice!
Wouldn't it be funny when we've tried our best to figure out such a complex way to communicate with them, and then when they arrived, they just telepathically learn our language and speak with it fluently?
Can you give an example of any animal or organism ever communicating by "telepathy"?
@@MuantanamoMobile My dog keeps telling you that you smell funny. Gonna answer him or what?
If I were first high schooler at that time, maybe I'll be loved to join on these class, It's totally interesting lecture 😀
This is awesome. I love seeing your videos on my bell notifications lol
This is incredible.
This is an OUTSTANDING video!!!!!
As a person who recognizes, and decodes impossible messages for a living, this talk is wonderful.
Carl Sagan is and will always be my hero.
Absolutely amazing
Really enlightening video. Thanks.
you can see how he used this approach in the film Contact. one of my favourites.
Nice of Bill Nighy to step in and assist.
The original and still the best
Really nice video!!!
Why is this video clip of a higher quality than the video of the full lecture?
Had it been up to me to decode the message, I’d still be working on it today, some 44 years later.
I can listen him all day.
Fascinating!
Wow. I learned something today about decoding those crazy 1's and 0's. I'm an artistic type that has a tempestuous relationship with math and physics. My brain does not compute. But if anyone could teach me...it would be Sagan. What a trip back in time to hear his voice again. The country was different then. Miss it. Thanks for uploading this little gem.
He's my all time fav.
The smartest person/communicator ever in my opinion.
I watch this episode time and time again, and it still makes my blood race
Sagan explaining pixels and basics of graphical computing hh,awesome...
"either way, we win"
Indeed!
This is good social skills advice!
This guy is awesome.
Genius iin explaining in easy methods
I am not a scientist by any means. I found that absolutely fascinating.
This really made me realize how much technology helps in teaching. Its hard to see without a comparison to the past. I bet visualization in 3D was extremely hard in the past and is now something we take for granted. What other things might become easy to visualize in the future? (thus leading to more people being able to understand it and become interested in it)
Takes me back to glorious Saturday afternoons whiled away with Hoffman's elixir and Sagan's Cosmos.
Me too!!!
Good thing celestial & terrestrial beings are patient with us. They understand that our emotions can often frustrate us and get in the way of communication. Most things are a lifelong marathon, consistent learning, not exactly an event. Though there can be major events that help us.
i really have to give credit to sagan, the day i saw his video on light speed posted on youtube 14 years ago was when i started asking why
share the whole lecture please
When reason takes a cue from art: confronted with the sheer impossibility of language, turn to use images.
This assignment in 1977...
In 1985 Carl Sagan releases his novel, “Contact”, where an alien species sends a message which, when decoded, reveals a video image and hidden in the message is a three dimensional drawing of a device that allows one person to travel to the origin of the message as a first step in interstellar contact...
In 1996, the World loses Carl Sagan.
In 1997, Jodie Foster stars in the motion picture adaptation.
2:08 - the body language of the kid in the sweater is great. I bet he bragged about it later, telling his friends that he enjoyed Professor Sagan's lecture.
Brilliant
Able to figure out the message is very cool
Thank God for people like that carry us all into the future.
This is gold dust.
One of the greatest humans to ever live in my mind
Where is the rest of Sagans full lectures in HD pls?
This... Dawkins...and Simon Conway Morris where the best Xmas lectures ever.
Smile, wave, and hope for the best.............
Cool to see a vintage Stony Brook University sweatshirt on kid in center @ 4:02. It looks like his little-brother to his right had one on too.
The third, and in fact generic, alternative is that that particular scientific endeavor neither "succeeds" nor "fails" conclusively (i.e., never halts).
In this case, the body of scientific knowledge got through ancillary hypotheses and experiments, as well as the body of methods and techniques (and even physical technologies) developed in conjunction with (or co/incidentally, alongside) the former developments/advances -- all, at least originally, in the aim of deciding the hypothesis -- _all accrue without limit._ The ROI for R&D is strictly positive. Always.
In other words: Science is a win-win-win enterprise.
More like dog-eat-dog.
We're all in this together. Happy New Year to you.

Listening from the ukwales❤️
While this is interesting to think about, it relies on many assumptions. The most prominent being that if we are putting a beacon out there for a more advanced intelligence to intercept, wouldnt that intelligence have already put out a beacon of its own that we are ignorant of? It seems to me that a higher intelligence would have a more efficacious strategy to start communication with us than we would have to initiate communication with it. We are the ones that need to pay attention and identify information with intent... aka meaning thats everywhere around us.
The kid at 2:06 is a grumpy boy lol
Contact was a really good movie.. I perfectly plausible possibility to the existence of alien intelligent life..
I love that kid at 2:10.
He's all like... this sucks. It'll take 2 years at light speed to get to the nearest star.
Math is a universal language everyone knows math to some extent EVERYONE
I don't
Yea you do
Not to the universe
@@joeyyc8515 I said universal language
That Kathy is smart! She realized it's a 31x31x31 cube and correctly guessed it's formaldehyde. I wonder what she accomplished in her career.
Why not upload the whole thing? would love to rewatch them, I know it's out there but not in this quality.
People like short videos!
so by that logic we are not people then...
We're glad you're enjoying some Sagan. All of the Christmas Lectures are covered by a rather complex set of copyright rules between several parties so unfortunately we are unable to upload full length videos onto KRplus. We are aiming to get our entire back catalogue online here though: www.rigb.org/christmas-lectures/watch
At 2:40 in, when you see the grad student at the head of the table, it's the Mitch Taylor character from the 1985 movie, Real Genius, that you're thinking of. Played by Gabe Jarret. You're welcome. I know it was bugging you too.
Great scientist.
Carl Sagan is my homeboy!
I think Dr. Sagan would be impressed at how many “channels”, or rather frequencies we are able to “listen” to at once. I don’t think it improbable at all that 50 years from now, listening to or rather being able to monitor frequencies from DC to Daylight all at one time will be possible while the antenna is pointed at one spot in the sky. And either the antenna rapidly moves to different spots, or perhaps dozens or even hundreds of antennas could provide instantaneous surveillance of most, if not the entire sky. Or rather, building on what Dr Sagan alluded....our ability to read all the local highway billboards and hear all the local radio stations, all at once, isn’t too far fetched? Perhaps this is nothing more than a pipe dream.
No you're right. New telescopes are going up all over the world. And the new move in SETI is to use all the resources of the internet to sift and store this data. Pretty soon, what you're describing will be fully realized.
Hadn't seen this before. Clever message but wouldn't they be scanning all frequencies for transmission anyway? It seems like the message in the movie Contact was better formulated.
The first thing you would do is establish the foundation of the communication method. Then one would ask about the third conceptual step if steps 1 and 2 in the universe are 1. matter/energy and 2. information. What is the third, higher step, in that sequence.
i love the internet, we can now, like never before watch and educate ourselves profoudnly in most sunjects for almost a penny, and listen back to the words of great people long gone
