📄𝗧𝗿𝗮𝗻𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:
In 1977, the Voyager 1 and Voyager 2 space probes were launched to study the outer solar system. After 45 years, Voyager 1 has traveled 23.8 billion km, or 159 times the Earth-Sun distance, and Voyager 2 has traveled 19.7 billion km. They’re the most distant human-made objects. A signal from Voyager 1 takes about 22 hours to reach Earth.
Because scientists knew these spacecraft would reach interstellar space, they decided to fix to their sides a pair of golden disks. If any intelligent extraterrestrials come across Voyager 1 or 2, they could learn about us and our planet by decoding the information on the disks. This wasn’t a new idea. Gold-anodized aluminum plaques had been placed on board the Pioneer 10 and Pioneer 11 probes which had been launched earlier. The golden records, however, contained much more data.
On the first side of each golden disk are greetings in 55 different languages, some sounds such as wind, thunder, a train, a bus, various animals, footsteps and some well known music such as parts from Johnny B. Goode by Chuck Berry, The Well-Tempered Clavier by Bach, and Beethoven’s Fifth Symphony. On the second side are images in audio form. Let’s think about, if intelligent extraterrestrials got hold of a golden disk, how they could decode the information it contains.
Step 1: Examine the appearance of the disk. As you can see there are some symbols on the record. For example, these symbols explain how to play the golden record. If we look at the first symbol there are vertical and horizontal lines. These represent ones and zeros. If we convert this binary number to decimal we get 5,113,380,864.
If we convert this binary number to decimal, we get 4,587,025,072,128. At first, these numbers don’t seem to make any sense. But if we have a key, we can transform them into something understandable. The key is this symbol. It represents hydrogen atoms. But notice that the electrons aren’t the same. One of them points up, the other down. The reason for this is hyperfine transition.
The electron in a hydrogen atom changes the direction of its spin spontaneously in about 10 million years. When this happens the hydrogen atom emits electromagnetic waves with a wavelength of about 21 cm and a frequency of 1420.406 MHz. As you know hertz means 1/seconds, so 1420.406 MHz is equivalent to about 7.04 x 10-10 second. Now if we multiply the numbers we found by 7.04 x 10-10 seconds, we get about 3.6 seconds and 3,229 seconds. 3.6 seconds is the time in which the record is to be spun around once, and 3,229 seconds is the total run time of the record. So we’ve found the speed at which to run the turntable. Now all the sounds and music can be listened to as they were recorded.
Step 2. If we listen to the 2nd side of record we hear these sounds (3). As mentioned before these sounds are actually the data of images. If we look at this symbol, we can clearly see audio waves and binary numbers. If we convert the binary numbers into decimal we get the number 11,845,632. Again if we multiply this by 7.04 x 10-10 seconds, we get 0.0083 seconds or roughly 8 milliseconds. When we examine the first symbol, it seems, the scan time should be 8 milliseconds. So we need to scan these audio waves every 8 milliseconds. Also this symbol shows that 512 audio waves form an image. So we’re ready to decode the audio waves.
Step 3: We need some powerful audio software, so we’ve chosen Audacity. It’s free and we’re familiar with how to use it since our videos’ sounds are processed with Audacity. Interestingly we struggled to find a copy of the golden records image sounds. After a lot of searching, we finally were able to find it. If we open the image sounds with Audacity we can see that the sound is stereo. That means there are 2 channels and both of them should have image data, since they have audio waves. Let’s split the audios and try to decode the first one.

Crossing our fingers the aliens have audacity installed
😂😂
Otherwise they're not as civilized as assumed.😁
We also have the hope they will look for a tutorial and find this one
(yes I am joking)
@@ritishifylets hope 😂
😂😂
Great tutorial! Helped me solving this puzzle. Gonna visit earth soon!
Without that key, I’d never know to figure out the length of the record by multiplying the numbers above by 7.04 x 10 to -10 power. Thank goodness for that key
Me as a alien trying to decode the golden voyager. But now i can decode it. Thanks for the great tutorial!
I feel like aliens are going to bring this back and tell us to stop dumping our trash in space 😂
EXCELLENT explanation of the decoding process! Good thing there is no photos of WINDOWS stored in the golden disk; that would greatly disappoint the aliens!
it's confused the greeting in chinese is“我们都很想念你们”which should translate as “we are missing you all”. how could the aliens be missed before we meet them?
I can imagine an alien civilization finding this and it being a huge deal for them. Just imagine if we found something like this
Next time, let's just send out a timelapse video of the space probe's journey, hoping the eyes of whoever will view it can perceive the screen's wavelength 🤞🏻
And how long battery will last? Or how long will be lifetime of your instrument?
This golden disc can last 10billion years!!

Okay so this is probably an extremely stupid question, but why did they write the images on a record where an alien would have to decode everything with no clue what it actually does instead of just sending photos or printed images?
Not a dumb question, I was wondering the same and I found that the complexity of the decoding process was intentional, as the record was designed to be deciphered by an advanced civilization that could understand the instructions and decode the images
Because the memory of the computer in voyager is several kb not in gb
Because over time radiation and other hazardous parts of space would slowly destroy any printed images. The disk is made of a special material specifically to avoid this
Because computers back then were extremely primitive compared to today. The Voyager computers only store data in kilobytes, compare that to computers today, many of which can store data in gigabytes or even terabytes. Also over time data on computers can break down due to radiation and other factors, so encoding them on the very grooves of the record will allow them to far outlast any kind of flash drive or memory stored on a computer.
@@therealspeedwagon1451 That wasn't my question. It's obvious why they didn't store it on the probe's memory. I wanted to know why they didn't send physical printed images.
Very informative
your voice is so perfect for this i love it
Great video. I guess if it’s intelligent life they should know how do do all this lol. I wouldn’t be able to
If the average person or even an astrophysist can't figure out how to decipher the encoded information. without instruction, from someone that knows how. How in heck do they expect aliens to figure it out. 😂 This is insane. Not to mention they have to construct and analog phonograph. I guess this would be like the Incas or Aztects, sending us a message of their civlization, to the people of 2024
Like bro they gotta be Nikola Tesla of math, metro booming on audacity and mark zuck with the coding... Like how the hell aliens supposed to look at that disk and be like ahh yeaa they're they are.
Should've drawn a picture of 2 humans and the sun or some shit.
@@timmartin7664A group of scientist could easily figure it out
Such great video and no comments! Guess I should do my part atleast
Yeah man i can feel you
If you're from future reading this i dont know how advanced your technology is right now
I just want to say
There is science for everything
You will find your answers in science
Awesome contents on this channel
Really cool
Well done, very cool, thanks
no way they gona solve that, they might eat it
thx for this great video!
Thanks for the great video, this video actually helps me quite a bit -because I am an extraterrestrial- because the voyager golden record is the subject of my grand presentation worth 10% of my diploma's grade
INFO #1 : @6:40 - According to NASA, this pictogram does not indicate that decoding should start when the third audio wave ends. It shows how these lines are to be drawn vertically, with staggered "interlace" to give the correct picture rendition. I assume that the circles represent the data (pixels) that form the image. You draw the first image line (From top to bottom), then go back to the top and draw the second image line and so on, up to the 512th image line. This being said, there is an image "EXPLANATION OF RECORDING COVER DIAGRAM", indicating scan triggering after the third audio wave. IMO this makes no sense, looking at that pictogram, there is no way for anyone to logically come to that conclusion without the footnote.
INFO #2 : @7:00 I believe the speed issue is due to the fact that these 12 in LP record are usually played back at 33 1/3 RPM and the Voyager record was recorded at half that speed at 16.65 RPM.
Are the stereo channels for the same image (as in combining the info from the two tracks produces a higher quality or color image), or do they each contain different images?
As I know each channel contains separate images.
Best wishes for you.
Realy I like this video so so much like you can imagine
Some questions for you :
After some research and trial and error , I managed to make a very simple code in python that takes as input the txt file exported from audacity and prints the image . The first time it printed the blurry , grayish image of the Earth I was speechless .
Here are my questions :
1) from what I understand audacity's sample data export just extracts the signal waves converted to dbm , right ? If that is true could you explain me the value you put in the sample data export window to "100000" ?
2) In the code , you extract the dbm's in each line of the text file , and then convert them to float , then do a round , and finally convert them to int , then I don't understand the calculation you do *(-1)*3 , what is it for ?
For my python code I did not need to convert them to hex .
Thank you very much for any answers , and great video !
Yes a bit more detail on those lines of code would've been nice. I was confused by the intval(round(floatval(...))) too, and the (-1)*3... presumably something to do with generating 3 RGB colours to make 1 pixel, but I don't understand the logic either.
What if the Alien getting hold of these records are outcasts Interstellar gold smuggler?
aliens coming here to see how to decode this damn thing
Who said this is simple to understand😮
Can you share the file to the image sound .wav?
Here you are drive.google.com/file/d/19IBBTMHq3mMhQxg1iSsOWEJEy6krA7y-/view?usp=sharing
Thanks, we appreciate you!
shouldve just put spiny disc image on it.. or make it auto play
I don’t think aliens will ever decode it.
Do you think we can solve wars, or climate change not yet. That 84 movie Starman was interesting to me.
It is crazy to think that in the 1970s there was no audacity or GarageBand or whatever fancy audio software. All this had to be done with primitive computers and human thinking.
I am crying
Now i realize this disc is meant for smarter more complex species who could somehow figure this out
Of course. What's the use of it being captured by some oogabooga aliens who can't even appreciate the presence of an alien civilization
It’s insanely difficult to decipher. I mean that key being the hydrogen hyperfine transition constant is such a huge leap to convert the binary code. They should give it to the best physics and maths students who have somehow never heard of the records to see if they would be able to crack the code.
Well you need a "key" which is available to an alien species, so you can't use anything like meters or square inch bald eagle democracys as a unit because it's made by humans. U need a fundamental unit which is universally available and the most fundamental thing in the whole universe is the hydrogen atom. So it kind of makes sense to use that.
What if our technology is unique and aliens are in totally different kind of intelligence
This seems very confusing are we sure there really gonna be able to read this?
We can only hope they are able to decode the map to earth on the front
the ironic thing about latin is it was stopped taught at public school after Vatican II conference decided that mass could be carried in respective language of a country where it's held, effectlvely killed latin as a spoken language.
If many humans can't. Don't think that aliens can . Question
. can humans understand if aliens sends their golden discs?
Kismat par ji rahi hai duniya 😅😅😅😅😅😅😅😅😅😅😅
How they can read that
Its way hard for an alian
Wouldn’t time be different for someone that’s not us??
Actually it doesn't matter. If they measure hyperfine time in their time, everything will work.
I hope aliens have Google out there…
Hi I saw her by Tim Hortons
Human’s greeting aliens in “peace” is funny. We are not even in peace with ourselves. We deserve to be alone in the universe if you ask me.
i always wondered how this would be done thanks. part of me would love aliens to find and decipher it, a bigger part of me thinks it's just going to get smashed on a rock in a billion years 🙃
The record will likely burn up with voyager on entry to another planet or star. Chances of it being caught by alien life while travelling is about the same as catching a grain of salt somewhere between our sun and the core of the Andromeda galaxy.
So first aliens have to watch this video before decoding.
So the key is hydrogen atom symbol, and you need to know that this particular symbol is a sign of something that happens every 10 million years, and apparently it’s common knowledge that this symbol tells you to multiply other parts of record by this symbols secret code key of 7.04x10 to-10 power which equals 3.6 seconds….safe to say this will never be understood if found.
Alien ethu kittiyal thalla thalli marikkum 😂
I really hope they know python or Java programming 😅. They can apply for a job on Earth
The aliens already have Voyager. Unfortunately, their copy of Audacity had expired.

They would have a team of scientist figure it out 🤡
Hi how are you

Could of just sent a record player....
they are need audacity first..
Should have sent a hard copy as well too, right?
The real question is: how the aliens are suppose to catch a space ship travelling at 35000 miles an hour without damaging it?!!!
Just keep in mind that it's 35,000 mph in relation to the Earth. For context, the earth is moving something like 67,000 mph around the Sun but we obviously don't feel it because we're moving with it. All this is just to say, is that speed is always relative. So the aliens could see this at a speed that's less or maybe much more than 35,000 mph. Earthlings can get things to that speed with rockets but who knows how it'll go down for the aliens. The bigger issue is that voyager still isn't moving fast enough to hit any stars for tens of thousands of years!
By catching up to it, grabbing it, then slowing down. Simple astrodynamics
@@muddybasilisk7526 simple on the paper
This is all mind blowing…. But how the hell is anyone supposed to know the equation of turning 1s and zeros into a billion number, and that needs to be multiplied by another equation that two circles equal….why not just write the final numbers out and equation instead of making it almost impossible to decipher?? These mathematicians are too smart for their own good…so smart they’re actually dumb in common sense
"write the final numbers"
and how are you supposed to do that in a way that an alien species can read it?
You can't use human-made conventions because they are random. Base 10 number system? Random. Seconds? Random. U need to use a universally and fundamental unit-system and the most fundamental thing in the universe is the hydrogen atom. And tbh a base 2 number system is also more fundamental than base 10.
This is ridiculous. 😂 The hoops you have to jump through and the assumptions made, I mean “it’s obvious this represents a hydrogen atom” 😂
Seriously? If another human can’t simply decode the message, what chance does an alien have? NASA, you’re too clever.
FACTS. HOW CAN ALIENS 👽 DECODE IT . IMPOSSIBLE
If a species is capable of retrieving voyager, surely they have a great understanding of chemistry, mathematics, and astronomy. They would likely be able to decode this given time. It might not be immediately obvious that the diagram represents a hydrogen atom but if you're a scientist trying to decode this you would be making a lot of guesses and trying to put yourself into the shoes of whoever sent it, and you'd probably figure it out eventually. Heck even without knowing that detail they could probably figure out the units of time by experimentation
@@dawson6294 or they could just keep adjusting the speed while spinning the record to get the perfect sound.
@@NateWithWho They could end up thinking we sound like Alvin and the Chipmunks

The audacity of this guy...
Typical human - Send a fax and before it leaves the solar system, it become obsolete.
Hate to think how much money NASA squandered on this. In the vast emptiness of space there is zero chance of Voyager ever being discovered by intelligent life form. They must have been very naive back then to think it was a good idea 🤣
Bruv, what alien bum is gunna have the slightest clue how to do this. They probably wouldn’t use numbers like we do
Number systems are universal. Same applies to equations. Only things like symbols differ.
How the hell is anything decoding this
I believe they were looking for complex species if they cant solve this the travel to earth is impossible
Alien life so intelligent they can hear pictures, lol
