📄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.

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.

@jb7650 Ай бұрын

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.

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.

@therealspeedwagon1451 5 ай бұрын

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.

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 !

@JasonElliott88 7 күн бұрын

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.

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.

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!

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

@jb7650 Ай бұрын

"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.
