Honestly, if aliens ever intercept our movie broadcasts without a concept of fiction, they're going to think we have transformers and sand worms. They're avoiding us.
Most importantly - Keep It Simple! - The message should be: "Hello, this is not random noise, spurious interference, nor a malfunction", i.e., sending confirmation that they found an ETI, us, is the most important information to convey on the first round of communication. That implies that an extremely low entropy message is needed. We have received intriguing signals such as Wow and BLC1 but could not investigate them during reception because the signals did not repeat or persist. We could not get independent stations in on the analysis nor could we configure our observatories to optimally capture the signals. It was too late! What I find frustrating is that when we send messages, we do little repetition ourselves, making it so much harder for ETIs to effectively receive us. It is unlikely that they are pouring all their resources into their SETI so, if they have the needed receive technology and they just happen to be listening from our direction, they won't corroborate the find and will be unsure it was us if it does not repeat. For us, SETI is a thankless task that needs decades or centuries of effort just to scan all reasonable source locations for an alien signal, so the vast proportion of the time, we are not looking at any particular place. Similarly, ETIs rarely look toward us. If we send signals, we need to keep repeating, perhaps continuously for years, so that ETIs will have a good chance of stumbling upon and confirming our message.
Given we appear to be in a period of universal history much much closer to the beginning than the end, then for all we know most alien life is at a similar standard of tech to our own.. probably not even extra solar yet for most of them. So yeah id send a 'Hey if you get this your not alone, we're out here'. Doesnt tell them where we are, but the thought that some alien radio astronomer at a desk one omglarc afternoon suddenly gets confirmation other life is saying hi... they'd be happy. Granted the poor aliens could make a beeline in the wrong direction and bump into some nasties, but personally I think any species able to travel extra solar distances are way beyond things like resource scarcity and conflict (we arent gonna do it until we fix those issues ourselves).
In old scifi movies they often solved the communication barrier by evaporating the aliens with lasers. Following that the aliens were quick to learn english, often with the help of Lt Uhura.

Intelligence is arguably the ability to both recognize patterns and problem solving. Without either of those, you effectively have nothing more than an unthinking creature that just gets born into existence, may learn a thing or two about hunting for food from its parents, before either getting sick with old age or being eaten itself.
@@Gogglesofkrome you could also include when the behavior of a concious being is founded upon mutable, abstract goals. Though I feel like there's still a lot of room for concteptual gerrymandering in there.
@@ianmeade7441 I don't think it is productive to label intelligence as a binary value that's either on or off. It is better to think of it as an gradient. There is a lot of variance in the amount of intelligence even within our species but especially so when considering all the species. There is no contest that many apes show some level of intelligence and can think abstractly to solve simple problems and to learn things, but it is far from what a typical human expresses.
As someone who has a master's in intelligence testing, currently doing my PhD in emotional intelligence testing, I would say that what Anton said made sense, but it's complicated. Concepts have difference definitions even between areas of science, so intelligence can mean different things. In science, while we aim for a descriptive definition that accurately represents reality, we often use definitions that are pragmatic, and geared towards the goals we have in research. In that sense, we know pretty well what intelligence is because we define what it is. In fact, areas that have different goals will have different definitions. You'll find a definition of human intelligence in cognitive psychology, but a different one in computational sciences that applies to artificial intelligence systems. Anton's sentence makes sense in the sense that we don't know what criteria we would use to classify a completely new life form from another planet as intelligent. And that doesn't even get into epistemology, and the fact that things in nature don't come in predefined boxes that you can just label; doing science is not like exploring a map where you slowly uncover, for example, where Europe ends and where Asia starts. It's more like looking at all the data you can get about the land (including the people and the culture there), and using common sense to guide data analyses to decide whether there even is something such as Europe and Asia. This is specially true in sciences that are more "abstract" than biology. Like, within physics there are natural "borders" like atoms; in chemistry, you have molecules and in biology, you have organules and cells. But even then, when you *really* get into it, things aren't nearly as clear as you'd imagine. For instance, what are the boundaries of an atom? What are the boundaries of a polymer? And in, biology, recently there was even news about "discovering" a new organ in human body (which was merely a change in classification; illustrating that the boundaries of an organ isn't clear either). But then there is psychology where you don't seem to be able to find borders at all. So science and scientific definitions are not at all "a copy" of reality as people think, it's instead very human, and different cultures might classify things in a completely different manner, and, in this sense, intelligence is what people say it is.
@@ianmeade7441 I believe that it's possible for something to be intelligent without having the ability to understand abstractions; something like an AI can be more intelligent than the average person, and still entirely lack the ability to abstract concepts in the same was as a person might
It’s nice to have this channel to take a break from all the ugliness of humans. Helps us remember that we are capable of more than destroying our home, being at war and ignoring injustice.

The most important question we will have to answer when finally finding alien life will be if we are the first civilization that *they* have found or if we are the 100th.
@@Name-cz5jj the universe, as far as we can tell now.. is infinite... if we literally find one.. we can expect there to be infinite other civilizations, however far spread out.. up untill then... im 100% sure the earth is a multi dimensional egg in a womb universe.. just waiting for the AI to pop out and transcend... you think a biological entity could rip out of reality... my bet its the AI?
If Aliens do receive our transmission they might unfortunately be like us and refuse to accept it as authentic unless it repeats, but we only broadcast these transmissions as one-offs so they never get that confirmation, just like we never got a confirmation of the WOW signal.
I assume that they send the message to the point in the sky where the target system will be when the signal arrives after the travel time in light years.
@@shanerooney7288 we aimed for where stars were 25,000 years ago, not where they are now, and not where they'd be 25,000 years from now. Not to mention in huge turn around time we won't be where we were when we sent it either..
A very interesting topic Anton. I see the desire to communicate with extraterrestrial life as captivating but at the same time something of great risk. We should keep silent in the face of the danger that more developed extraterrestrials will come to our planet with plans of conquest. Better let them send their signals to Earth.
I've heard this point before, and I'm split on whether I agree. The problem is that it assumes "conquest" is a thing that developed alien civilizations would be interested in. I think that's a flaw we're projecting from us to others! And for me personally there remains hope that a more advanced species was less stupid and figured out how to be happy with what they got, rather than striving for eternal expansion. So, while of course there's the risk that other civilizations will be hostile toward us, I think going in with that assumption says more about us than about them. Maybe you're right, we're just not ready to communicate with aliens.
@@barryscannell conquest is literally what they said. Besides, that's a purely theoretical problem; if we were a bit kinder to our planet, there's no reason we would be running out of resources anytime soon. I expect a super advanced alien civilization to be sustainable.
@@barryscannell ok I did, Dark Forest Theory doesn't refer to finite resources (which on the universal scale is a purely theoretical issue). I kind of get the reasoning behind it.... and I disagree. I've explained this disagreement above. And even if hostile entities exist in the universe, it seems pretty cowardly to just stop reaching out for fear of that being a possibility. I want to see as much as possible of the universe. If there are alien species, I want to meet them and make positive exchange with them. And I would hope that most advanced species think the same way. If these desires turn out to be our downfall in the long run, then so be it. At least we died doing what we loved, rather than cowering in fear in our corner of the universe, waiting to be found and killed eventually anyway. But I guess that's just a matter of priorities, and it's fine if you disagree on that.
Evolutionary biologist Ernst Mayr debated exobiologist Carl Sagan in the late 1990s. He argued, not that there was no extraterrestrial life, to the contrary, but that "intelligence" itself is a evolutionary dead end. After all, the only example of "intelligent life" we know anything about are Homo sapiens which have existed only a few 100,000 yrs. and already, compared to all the creatures on earth that have existed for millions of yrs, we're seemingly dedicated to our demise as well as the planet on which we reside.
I think this Ernst Mayr guy was full of crap. Plenty of species on Earth have unwittingly driven themselves to extinction throughout the ages. Our intelligence and adaptability might be the very thing that will save us.
Of all the proposed solutions to the Fermi Paradox, my personal favourite (if for no other reason than it's a most optimistic...and nerdiest) is the "Prime Directive hypothesis." The idea that perhaps an advanced alien civilization has known about us for a while and has been monitoring our progress for some time now, but by their own cultural laws are not allowed to make first contact or intervene in our development in anyway until with reached a certain technological, sociological or biological threshold. Like, maybe they want to wait until we get over this whole "waging wars and polluting the ecosystem" phase before they deem us ready to be invited into their Federation.
@@Name-cz5jj Thing about space is...it's big. I highly doubt there will be any resources in our solar system that won't be abundant everywhere else in the universe.
It does seem pretty cool...I guess. It's definitely not the most realistic, but, if anything, it just feels kind of rude. Can't they just help us out themselves instead of letting us all die? IDK
@@xiphactinusaudax1045 That's one major criticism levied against Star Trek's Prime Directive. But the thing is even within our own species the concept of "ethics" and "right and wrong" differ from group-to-group and even individual-to-individual. Who's to say an advanced alien race might not have an extremely complex and sophisticated set of "morals" and "laws" that to us seem cold or bizarre because they are literally alien to us? Maybe they've tried making first contact with other civilizations before they were ready and it ended badly for both parties so they decided it's better to let a species figure it out for themselves than be partially responsible if things go wrong.
@@Name-cz5jj No, they could help them along the way. They are advanced, there's no reason they can't just ease into it and help them out. Who ever said that they would be getting technologies they aren't responsible enough to possess? There's many ways of going about contacting an intelligent civilization that wouldn't end badly
@@AceSpadeThePikachu But wouldn't it make more sense to come up with solutions to the problem rather than avoid the problem whatsoever? Isn't that how innovation occurs?
I'm not an advocate for METI (SETI is fine) however, instead of sending our location as a stationary point in space, (at the time of the transmission of the message), would it not make more sense to outlay our path in the universe for the next, say, 1,000 years? that way any recipient of the message could 'simply' check our stars path to find us, hopefully peacefully (hence my apprehension for METI)
There seem to be a lot of obvious process steps that never get mentioned in most of these videos. Either because they're so obvious that they can be taken for granted, or because they've been overlooked/brushed under the carpet by the teams who are proposing to send the messages. You decide. My list starts with: (1) "Radio" is really electromagnetic radiation, so where on the spectrum of potential frequencies are "we" broadcasting [why would aliens be looking where we're broadcasting?]; (2) is it aimed in the right direction to arrive at the targetted place at the right time after years of travel [already montioned by another commentator - it's pretty pointless aim where we see the target today]; (3) what is the message's duration [how long have the aliens got to receive it before it's gone past them]; (4) how many times is it immediately repeated [to allow for potential signal dropouts to be filled in]; (5) is it rebroadcast multiple times after some amount of delay [to demonstrate that it's not a fluke]; (5) if the target is close enough is anyone here listening for a possible reply; (5) how easy is it to decode [viz Nobel Prize winners need not apply]. There are doubtless many other issues that others could add.
1) my training and passion being electronics and radar.... the EM spectrum is pretty large, even when considering "radio" and microwave. From a physics standpoint, provided our local understanding of physics scales to large distances, we are broadcasting in ranges likely to be monitored by aliens that use anything similar to what we understand as technology. There is some possibility they advanced straight to magic as far as we are concerned, but if they understand electromagnetism half as well as we do, or twice as well, then monitoring the radio and microwave spectrum would be rather obvious to do, if you are looking for other aliens. A full explanation goes a bit beyond a YT novel, but suffice to say that we can monitor a very broad range of the spectrum using the same or very similar equipment with no major material processing hurdles. Things get a bit different when you enter the visible spectrum and the wavelengths start to intersect with metal grain sizes or sub-micron structures. That is when physics doesn't really change, but our models of what happens go through a very janky set of transitions to describe why bulk behavior doesn't continue down to the atomic scale. As for whether or not they have the systems to decode the message... hopefully they are recording and can analyze it to start trying to make sense of it. 2) probably. Hard to know for certain, but even if we shot heavily collumated laser beams, the wave front spreads out enough that there's a rather high probability that failure to account for a systrem's movement would prevent them from intercepting. Basically, the wave trades amplitude (probability of detecting a photon per volume area/moment) for coverage (same number of die rolls, just more locations rolling spot checks). 3 and 4 .... going to have to ask someone who worked on it or studied it more than me. I would presume they had some kind of broadcast schedule and broadcast several times, possibly over the course of weeks/months. We do have systems listening for things in general. There is a healthy chance we would notice if someone broadcast back. Though this assumes they would reply in kind. They may just hop in the proverbial car and come over to say hello. We, still back in the days of crawling on our stomachs, may not appreciate the growing show of people walking around. 5 ... the question about encoding.... (or was it six).... is a long, long discussion about math, assumptions fundamental to humans, theories on how aliens may think or structure information, etc. You can bet that if we got a signal from another star which did not appear natural would have all manner of scientists and theorists pouring over it for clues on what it was and how to make use of it. To some extent, we have to presume aliens would be similarly attentive and be willing to search our signal for patterns or clues as to how to make sense of it. And be sure to leave enough clues and mathematical relationships in the structure to try and check our human intuition and let math do the talking. We can't do much with aliens who see an obviously unnatural signal and don't bother to study it. There's no "give a damn" ray we can package along with it. In all seriousness, it's all a bit of a long shot. But it's not like we are sacrificing large amounts of resources to toss a few radio signals out and see if anything comes back, either. If I gave you a ten billion sided die and said you could roll it as often as you want to try and get ten thousand ounces of gold... and rolling costs you nothing but a bit of attention... you would probably roll it a few times out of sheer curiosity.
And i would add to all of this:i think the life in the universe(especially intelligent life) is so RARE in the universe,and the universe is so VAST,that,we,as a species,will be long gone before something else catches these broadcasts or everything else the humanity sent into deep space.
@@Aim54Delta I like your points. I feel your 1 runs on many assumptions, given how meandering our path of science has been throughout history, and that we’re speaking of evolution on another planet with a different atmosphere and geological structure… I don’t think taking for granted an ease of developing a certain technology is very prudent…. To me that’s as much of a blind spot as believing your universal code could be understood by anyone, because you authored it, when even the brightest couldn’t figure it out. For 2, I love the physics, yet we’ve only practiced and interpreted them in our little bubble out here on the edge. I feel a simpler explanation could assist your points too; tracking orbital movements is an ancient science and to suddenly not account for trajectory in sending a signal doesn’t follow the current model. Unfortunately, because we’re in that bubble we don’t really know how our signals may degrade. I would also add, I feel it’s also a bit presumptuous to assume any pattern to repeat a signal would be perceived by extraterrestrials as an intended signal. Have we ever tried deciphering a repeating signal (:edit: from outside our bubble) after discovering it’s machination? Why would they?
Great comment. Since we don’t see any information in space that leads us to believe there is nothing out there but we know there must be them maybe intergalactic space is not following our rules of electromagnetic radiation. Maybe dark matter is essentially erasing the information. Or just coding it in a way we haven’t learned to read or even look for yet. We are so primitive that we can’t even explain light or gravity yet. We are only a few hundred years into this new era. Time will tell us many new and amazing things. I have no doubt about that.
I think it's incredibly naive for us to think we can communicate with aliens when we can't communicate with a single other species *on earth*... Edit: Lots of people in the replies saying that "we can train animals to communicate" are entirely missing the point... First, you aren't "communicating" with your dog because you can tell when they want walkies. Second, we aren't talking about the domestication of a known alien species. We are talking about sending a disc with some scribbles on it into unknown species territory and expecting them to have the intelligence and sophistication to understand *extremely* foreign languages. It's like trying to train a dog by throwing flash cards at them... Domestication of animals is a long and arduous task, your dog is bred purely to be domestic and still it's a struggle sometimes... The only arguments I see for aliens understanding our language are: 1) "*Intelligence* was made in the image of God, not just man." Meaning all intelligence in the universe was seeded by a common ancestor and that language develops the same regardless of external stimuli. Why would life, separated by lightyears, evolve so closely as to develop language structures similar enough to understand? (Just look at how different written English is to something like hieroglyphics, and that's *only* separated by time; Compare it to Cyrillic for a space seperation. And now multiply both these dimensions by orders of magnitude...) The only answer I've heard is "intelligent design". But seeing as we made pugs and poodles out of wolves and dingos; Either evolution is real and susceptible to influence, or all actions must be preordained by "God". Which in itself is a logical fallacy as it's a completely unprovable appeal to authority that sets up another unanswerable question; If there is no freewill in existence, no chaos in the universe, why is everything? 2)They are so far advanced in there cryptography that they can decipher completely alien code. If this is the case and we are in proximity to get a message to them, they know we exist and have chosen not to communicate. It makes no sense that they have the technology and intellect to decipher our message (which many of our own scientists, who have much common knowledge, couldn't do) but don't have the technology to reach out to us in a more acceptable language.
We can communicate with other species in as much as they are willing and able. My dog and I communicate at the level he is capable. We have established norms and can convey needs, commands, warnings, emotions, etc. Granted we both know the other one can see and hear. If my dog was smarter then we'd communicate even more. Sure, he was bred to care what I do, but other non-domesticated animals can communicate similarly...they just aren't predisposed to care as much about what man does if it isn't survival related.
We are also the only technological civilization on earth, so.... We also domesticated plenty of animals and even changed their genetic makeup to suit our desires (dogs and cats)
I hope you've read at least some Ted Chiang short stories, he deals A LOT with language and communication. But one of his stories is precisely about this (communicating with other species on earth), it's called The Great Silence. It is in his collection called Exhalation: Stories.
I've seen a lot more concearn for the Dark Forest theory expressed recently (probably from Kurzgesagts fantastic video about it) and I'd like to add something I really hope everyone keeps in mind. Picture a super-advanced, entirely genocidal race of beings; powerful enough to make the whole galaxy look devoid of any intelligence, except for us, who they haven't found yet. So why would we even be here? If their urge to purge is so absolute, why even wait for other intelligence to develop in the first place? Let's say this super advanced, genocidal civilization detects primitive radio messages from another star. Given the timescales of interstellar travel, they know that any fleet they send there won't be arriving to a primitive civilization. In all likelihood they have a multi-thousand year long voyage ahead of them, so if the original senders of the message don't wipe themselves out, then there is easily enough time for them to progress to the same (or even greater) level of technology as the inbound fleet, given they already have radio by the time the fleet first departs. So how does the super advanced civilization solve this problem? They don't wait. They look for any planet with any kind of biosignatures (or even potential for habitability), and they send a probe to dismantle it ASAP. This is perfectly in line with the logic of something so aggressive as what the Dark Forest hypothesis suggests. Because if they ever detect radio signals, then they'd know they're already fucked. In all likelihood, they would now already share the galaxy with another monsterously powerful, incomprehensible, multi-headed super organism. And they know it will eventually learn what they've been up to. From this you could potentially have a 'Dawn Forest' Fermi-paradox solution, in which this scenario did actually play out in the Milky Way, except the super predator civilization recently faultered, and subsequently got it's ass kicked. Only just now would intelligence like us have a chance to get going again naturally. Perhaps most of us aren't advanced enough to detect one another yet, and the galaxy still looks very empty. Considering that Earth has had detectable oxygen for the last few billion years, and nothing in all that time has wiped us out, I think we're ok. Anything that could come and destroy us before we're advanced enough to fight back would have probably already been on it's way here long before we invented radio.

Btw E Square, time is a meaningless concept in the pit that is the TH-cam comment section. 3 hours spent writing an argument to "no u" is a warm-up for almost anyone you find here.
The dark forest hypothesis parts from the false premise that intelligent species would "compete" for anything in the galaxy: Space, resources, etc. But in reality the need to compete for any of those things may be non-existent. Our stellar vicinity alone contains more real estate and more resources than the human civilization would ever hope to consume. Combine that with the fact that more advanced species will most likely be more efficient and consume less resources than any of our estimates, and there is no reason for any aggressive civilization to exist, let alone spend their time fighting any potential "competitor" in the galaxy. Space is too empty and too big, and the galaxy contains so many resources, they may as well be unlimited. Hypothesizing about extraterrestrial politics by drawing comparisons with the history of humanity assumes many false premises. Extraterrestrial civilizations will not share one planet with non-renewable resources, to begin with, and space is more difficult to travel than any ocean. Maybe they would have ideological reasons to expand aggressively and attack their neighbors without provocation, but not for resources or territory, and the chances of such civilizations to exist and survive for a reasonable amount of time are very low.

@@fiona8627 lmfao no you’re right it’s hilarious but it gives me second hand embarrassment, like why does the stick figure have no head?? Why are we giving them the recipe to life?? In Tetris form??
Why don't we just send out a unique signal that repeats every 20 seconds (like the first 60 numbers of PI or the like) an transmit it at different frequencies. That's what SETI is looking for.
It's because the beacon transmiting this signal would have to be extreamly powerfull, if you want your signal to be detectable on significant distances. Building such a thing is a waste of time. We know that there is nothing in our neighbourhood, so we would have to reach further, and then time comes into play. Nobody is going to wait for hundreds of year in hope that someone will reply to a signal sent millenia ago, on random frequencies hoping that someone is actually listening. All the resources we waste on SETI should be allocated into developing and building powerful space telescopes, because they potentially can detect biosignatures, and if they do, we've got something to work with. And even if they don't, they will discover a bunch of other thing, so it's not a waste.
@@tomekkruk6147 The more advanced society becomes, the more we integrate ourselves with nature around us, instead of trying to change nature and the more we try to become quiet instead of loud and obnoxious. And the fact that communication through gravitational waves is a thing now, and quantum communication.

And only 80 years since it was built in theory.
@@SMGJohn Gravitation waves communication? Mate, Less sci=fi more science. We can barely detect them at present, and it takes a catastrophic event like neutron star collision for us to even hope to detect something, not to mention creating them to communicate on interstellar distances. Same with quantum teleportation (i assume that's what you meant, as quantum communication is basically an idea to protect data you send) - no information is being sent as superluminal speed, so yeah, you're talking nonsense i'm afraid. Obviously, there is a possibility that some laws of physics exist that allow these things, but we yet have to discover them. But at the moment nothing really indicates that that's the cases, so we should stick to what we know and to methods that actually produce meaningful results. SETI and similar programmes have nothing to show for, despite years of trying, so all the resources should be allocated somewhere else.
@@tomekkruk6147 What? I am telling you that we do not fully understand everything and aliens might try to avoid beeping out radio signals left and right to begin with, communication through radio waves is extremely energy consuming and not to mention the time delay is irrational for space com. Whatever they are using, has almost no delay over vast distances, is not detectable by little children like humans playing in a sandbox with technology thats probably thousands of years behind anything thats remotely intelligent enough to travel between star systems. And even if there were civilisations on equal terms of us, we would been able to detect changes in the atmosphere from their activity, something we have not yet been able to do apart from a few anomalies here and there that are not well explained and could equally have natural explanations just as much as the alien one.
I never thought about self reflection giving such insights. It's possible, but I think humanity's inhumanity needs to be reigned in first. Gives me hope to think about that though, thanks Anton.
@@theluftwaffle1 Yeah i read this and thought: we have no fucking clue who's listening. Just think about what we are capable of and add intergalactic travel n shit... terrifying!
I disagree. Any species with the ability to travel interstellar distances will have secured the technology to detect us millennia ago. This is a great way to reach any potential neighbours and declare "We're here, we're friendly, we just want to talk". Of course, our best current understanding of the situation is that we are alone. We might be the only intelligent life in the Milky Way.
It would seem that the only signal that could be received and make sense to an alien civilization would be a binary signal, Morris code if you will, in which we tap out prime numbers. Otherwise how could any alien civilization possibly understand how to interpret different codex that we have created for sending images? Always great to watch your videos!
I read a short story where aliens came to Earth after a global ice time had wiped everything out -they find a strange can with a roll with a long strip of images. Their scientists find out that if you play the pictures after each other in a fast progression it creates an illusion of motion. They play the images and become really confused by all the strange things it shows especially the series of symbols that ends the whole thing and becomes a riddle for the scientist for the years to come -the words "Walt Disney".
I don't remember the title. I saw it in a short-lived magazine back in the eighties. It's possible it was written by Arthur C. Clarke but I'm not sure.
We should send the message “26” in binary to indicate how many letters we have, then give binary equivalents for each letter and a good bit of numbers. Then say: “we are sentient. We are here.” Hopefully that is enough, in binary and Morse as image and sound
@@willhall4037 Face it some are already here. They have been helping us. They have been warning us not to send messages into deep space because not all aliens are helpful.
I think the main point of the original message was to have fun putting symbolic meaning into something that is really mostly about designing a message that “looks” distinctly artificial. I’m curious how the messages were modulated
Harrumph! I have two serious issues with deliberately sending messages: 1) It's a really, really, really, bad idea! Made worse in providing a return address. Do I have to explain why it's such a bad idea? 2) For any individual or group to take it upon themselves to send a message to the stars on the behalf of the human race is the very definition of hubris!
Does a radio signal travel to the target planet and pass by (needing a civilization there at the moment it passes by to receive it) or does it stay there forever?
Passes right on by. That’s why it’ll never work as a non repeating signal. The chances of timing it just right in the grand scheme of the things is just not plausible imo.
that why i like being a nerd, other peoples when drinking. throw party, got into a fight etc... nerd ? drunk? let send love message to those sexy aliens!
@@striker851 hmm yeah. But at a point we have to think about how when it comes to aliens our logic and representation become subjective. I would say that they need non scientists on that team, because of the nature of thinking required. Like if I was an alien species looking out for life everywhere then any narrow band signal with patterned pulses maybe showing a temporal, spatial location of earth using hydrogen would spark my interest, maybe they are also assuming hostile species but giving them more info is detrimental to us, like hey these are our weaknesses come kill us. And maybe just what humans look like. Like the japanese scientist did.
Honestly, the idea of sending messages is almost pointless because there are so many things that need to be just right. The astronomically low chance that something actually picks up on a message, most non scientific people/ aliens would have no clue what they're seeing and would most likely discard it. The thing that we need to focus on is more non-natural shapes. If we show something that must be unnatural, they are going to take it serious and not discard our message. Much like the WOW signal we got, we still have no real answer to it and it is something that is brought up all the time. Being said, while sending messages is almost pointless, it does have value; just on the off chance, just maybe, somewhere, somehow, something will pick it up.
Broadcasting our existence, level of technological achievement, and location, seems to me about as wise as walking through the bad part of the city at 2am, carrying an enormous, heavy bag with a dollar sign on it, and leaving breadcrumbs in the form of dead presidents. That is, it seems very unwise.
Not really If aliens can do harm to us they can sterilize planets so that life cannot even appear, they also have bigger telescopes and are generally more advanced so they could detect our radio signals that we use for communication
Such messages are like mosquito buzzing, they only prompt real universe powers to end us with one move of "hand". We are stupid mosquitos... . You have COMMON SENSE MAN!!!!! One of few in this thread....
Repeat the Fibonacci sequence 1, 1, 2, 3, 5, 8, 13, 21 in simple pulses of energy in multiple frequencies and at different rates in a cycle. Then they can easily detect and confirm that they are seeing a signal.
there's no way to hide in space. we can't block our transmissions and if we could there should be an IR signal showing something is odd. if you have a species out there capable of doing anything about our messages there are some safe assumptions. first, we can assume there is a logic to their actions because they would need advanced logic to make any kind of communication. second, we can assume that they have some form of cooperation that allowed them to build technology, which implies compassion or at least some kind of value system. third, we can assume that they don't have either or both the ability or the desire to conquer the galaxy because if they wanted to and could they would have done so already. it's not hard for a k2 civilization to use their star(s) to sterilize every rock in the galaxy and wouldn't take long on cosmic scales to colonize every star in the milky way at sub-light travel times. fourth, we can assume that any extraterrestrial intelligence would evolve some kind of sensory perception, and if they have technology they would use it to interpret things they cannot perceive. if not for curiosity's sake then for science, defense, or just because they can. they're going to be very different but will certainly have commonality with earthlings. if i, an octopus, can learn to think and write in human, humans can learn to think and wrote in extraterrestrial.
No reason to worry about sending messages when the entire planet is projecting "here we are" like some kind of car dealership at night with those giant lights seen for miles away. Heck could just ignore radio and just point a telescope at earth and detect phosphine, methane, oxygen.
Might be an idea to send Morse code alphabet. Then send same message in Morse code in a couple different writing type of language. On repeat to various areas. If they can pick up radio, they might figure out some simple messages. Or linear message that shows initial different tone for arrow direction, that shows our Sun and planetary system. One type of radio pulse for a while to say straight, one to determine left and one to determine right. Messages can be sent in the form of pictures using three different radio pulses. Like drawings where as the pen is never lifted off of the paper. Very simple and basic.
The other thought is the use of the words “intelligent” and “alien”… 1. Intelligent - we use ourselves as a baseline but look at what we’re doing in Ukraine… 🤷♂️ 2. The concept of “alien” describes something foreign to us but…, how foreign are we to them? ie. we’re the aliens…! I wouldn’t be surprised to learn there are hundreds of other civilizations operating in a federation and have all agreed to NOT communicate with us in anyway because of our poor behavior and until such time we actually mature and evolve as citizens so we can join and participate in this federation as well - until then we’re on our own… 😔
They did respond to Sagan's message from Aracebo - the reply came back in crops flattened , and still harvestable. The response was Similar, with genomic info , star system layout , some codeing in binary format .
They've been here already. Ancients watched a war in our skies. I forget my source for that. I saw one a few years back. They hang out around nuclear sites too. I hope they're going to disable the damn things.
We had a response from that first message in the form of one of the most complex crop circles ever made, it was so complex that was only truly visible during a certain time of day to provide the perfect shade on the crop. Proven to not be fake.
If I thought for just one moment that this would be my last breath, I'd tell you I'll love you forever, even beyond death. If I thought for just one moment that your face would be the last I'd see, I'd take a million pictures and save them just for me. If I thought for just one moment that your voice would be the last I'd hear, I'd listen attentively and promise not to shed a tear. If I thought for just one moment that your touch would be the last I'd feel, I'd embrace you and know that this has all been real. If I thought for just one moment that my heart would beat its last beat, I'd thank the Lord for allowing us to meet.
While it's fun to imagine an alien civilization receiving an old I Love Lucy episode and having a "wtf" moment, the reality is that most of those radio and TV signals lack the power to propagate very far once they leave Earth. By the time they reach the Kuiper belt, much less another star system entirely, most of those signals will be barely discernable above the background noise of the universe. If they're more advanced than us, then it's more likely they will detect our atmospheric composition and determine that life exists here -- possibly even technological life if they can detect certain artificial compounds in our atmosphere.
Fyi it now says: "hello wonderful aliens, this is anton"
doesn't the fact that ever signal found in the background noise for 1970s was never aliens mean that background wasn't the background

Honestly, if aliens ever intercept our movie broadcasts without a concept of fiction, they're going to think we have transformers and sand worms. They're avoiding us.
I love this, it's so wholesome and fun.
Galaxy Quest illustrated this quite nicely.
I mean, if they don't have fiction/imagination how would they dream up a radio telescope to listen to the message in the first place?
They'll see the Nuclear detonations flashes first and assume we've killed ourselves.
I don't think they'd be that dumb, but yeah, pretty funny to think about.

Such messages are like mosquito buzzing, they only prompt real universe powers to end us with one move of "hand". We are stupid mosquitos... .
I was thinking more like:oh so they still have no idea that we are already visiting earth.
earthlings is a pretty ugly name for us. Terrans are better.
Most importantly - Keep It Simple! - The message should be: "Hello, this is not random noise, spurious interference, nor a malfunction", i.e., sending confirmation that they found an ETI, us, is the most important information to convey on the first round of communication. That implies that an extremely low entropy message is needed.
We have received intriguing signals such as Wow and BLC1 but could not investigate them during reception because the signals did not repeat or persist. We could not get independent stations in on the analysis nor could we configure our observatories to optimally capture the signals. It was too late! What I find frustrating is that when we send messages, we do little repetition ourselves, making it so much harder for ETIs to effectively receive us. It is unlikely that they are pouring all their resources into their SETI so, if they have the needed receive technology and they just happen to be listening from our direction, they won't corroborate the find and will be unsure it was us if it does not repeat.
For us, SETI is a thankless task that needs decades or centuries of effort just to scan all reasonable source locations for an alien signal, so the vast proportion of the time, we are not looking at any particular place. Similarly, ETIs rarely look toward us.
If we send signals, we need to keep repeating, perhaps continuously for years, so that ETIs will have a good chance of stumbling upon and confirming our message.
Excellent point!
Which is exactly what those clever Vegans in "Contact" did!
Given we appear to be in a period of universal history much much closer to the beginning than the end, then for all we know most alien life is at a similar standard of tech to our own.. probably not even extra solar yet for most of them. So yeah id send a 'Hey if you get this your not alone, we're out here'.
Doesnt tell them where we are, but the thought that some alien radio astronomer at a desk one omglarc afternoon suddenly gets confirmation other life is saying hi... they'd be happy. Granted the poor aliens could make a beeline in the wrong direction and bump into some nasties, but personally I think any species able to travel extra solar distances are way beyond things like resource scarcity and conflict (we arent gonna do it until we fix those issues ourselves).
Your logic is impeccable sir. I believe you are correct.
@@NZBigfoot Where is yours is all over the place. You are coincidentally presumptuous.
25,000 years from now some alien observatory receives their "wow signal"
In old scifi movies they often solved the communication barrier by evaporating the aliens with lasers. Following that the aliens were quick to learn english, often with the help of Lt Uhura.
Might explain why ET isn't too keen on picking up the phone :P "Those furless monkeys on Earth are totally cray-cray!!"
Zapping with lasers works for all kinds of training

Frankly, to decode anything what you need is a context and a big enough sample. So far, no deliberate METI signals have provided these.
I always appreciate your hard work - like the video every day like clockwork - your attention to details - like always remembering the relevant links - and your dedication to humanity, like your current fundraiser. You are, indeed, *the* wonderful person!
A wise statement: We don't know what intelligence is. A sign of intelligent questioning and observation :)
Intelligence is arguably the ability to both recognize patterns and problem solving. Without either of those, you effectively have nothing more than an unthinking creature that just gets born into existence, may learn a thing or two about hunting for food from its parents, before either getting sick with old age or being eaten itself.
@@Gogglesofkrome you could also include when the behavior of a concious being is founded upon mutable, abstract goals. Though I feel like there's still a lot of room for concteptual gerrymandering in there.
@@ianmeade7441 I don't think it is productive to label intelligence as a binary value that's either on or off. It is better to think of it as an gradient. There is a lot of variance in the amount of intelligence even within our species but especially so when considering all the species. There is no contest that many apes show some level of intelligence and can think abstractly to solve simple problems and to learn things, but it is far from what a typical human expresses.
As someone who has a master's in intelligence testing, currently doing my PhD in emotional intelligence testing, I would say that what Anton said made sense, but it's complicated. Concepts have difference definitions even between areas of science, so intelligence can mean different things. In science, while we aim for a descriptive definition that accurately represents reality, we often use definitions that are pragmatic, and geared towards the goals we have in research. In that sense, we know pretty well what intelligence is because we define what it is. In fact, areas that have different goals will have different definitions. You'll find a definition of human intelligence in cognitive psychology, but a different one in computational sciences that applies to artificial intelligence systems. Anton's sentence makes sense in the sense that we don't know what criteria we would use to classify a completely new life form from another planet as intelligent.
And that doesn't even get into epistemology, and the fact that things in nature don't come in predefined boxes that you can just label; doing science is not like exploring a map where you slowly uncover, for example, where Europe ends and where Asia starts. It's more like looking at all the data you can get about the land (including the people and the culture there), and using common sense to guide data analyses to decide whether there even is something such as Europe and Asia. This is specially true in sciences that are more "abstract" than biology. Like, within physics there are natural "borders" like atoms; in chemistry, you have molecules and in biology, you have organules and cells. But even then, when you *really* get into it, things aren't nearly as clear as you'd imagine. For instance, what are the boundaries of an atom? What are the boundaries of a polymer? And in, biology, recently there was even news about "discovering" a new organ in human body (which was merely a change in classification; illustrating that the boundaries of an organ isn't clear either). But then there is psychology where you don't seem to be able to find borders at all. So science and scientific definitions are not at all "a copy" of reality as people think, it's instead very human, and different cultures might classify things in a completely different manner, and, in this sense, intelligence is what people say it is.
@@ianmeade7441 I believe that it's possible for something to be intelligent without having the ability to understand abstractions; something like an AI can be more intelligent than the average person, and still entirely lack the ability to abstract concepts in the same was as a person might
It’s nice to have this channel to take a break from all the ugliness of humans. Helps us remember that we are capable of more than destroying our home, being at war and ignoring injustice.

The most important question we will have to answer when finally finding alien life will be if we are the first civilization that *they* have found or if we are the 100th.

If Aliens do receive our transmission they might unfortunately be like us and refuse to accept it as authentic unless it repeats, but we only broadcast these transmissions as one-offs so they never get that confirmation, just like we never got a confirmation of the WOW signal.
I assume that they send the message to the point in the sky where the target system will be when the signal arrives after the travel time in light years.
We aimed for the stars.
But we should have aimed for where the stars are going to be.
@@shanerooney7288 we aimed for where stars were 25,000 years ago, not where they are now, and not where they'd be 25,000 years from now. Not to mention in huge turn around time we won't be where we were when we sent it either..
A very interesting topic Anton. I see the desire to communicate with extraterrestrial life as captivating but at the same time something of great risk. We should keep silent in the face of the danger that more developed extraterrestrials will come to our planet with plans of conquest. Better let them send their signals to Earth.
I've heard this point before, and I'm split on whether I agree. The problem is that it assumes "conquest" is a thing that developed alien civilizations would be interested in. I think that's a flaw we're projecting from us to others! And for me personally there remains hope that a more advanced species was less stupid and figured out how to be happy with what they got, rather than striving for eternal expansion.
So, while of course there's the risk that other civilizations will be hostile toward us, I think going in with that assumption says more about us than about them. Maybe you're right, we're just not ready to communicate with aliens.
@@ilonachan Not conquest. Resources are not infinite. It’s an evolutionary imperative.
@@barryscannell conquest is literally what they said. Besides, that's a purely theoretical problem; if we were a bit kinder to our planet, there's no reason we would be running out of resources anytime soon. I expect a super advanced alien civilization to be sustainable.
@@ilonachan No I mean resources in the universe are limited. Look up dark Forrest theory.
@@barryscannell ok I did, Dark Forest Theory doesn't refer to finite resources (which on the universal scale is a purely theoretical issue). I kind of get the reasoning behind it.... and I disagree. I've explained this disagreement above.
And even if hostile entities exist in the universe, it seems pretty cowardly to just stop reaching out for fear of that being a possibility. I want to see as much as possible of the universe. If there are alien species, I want to meet them and make positive exchange with them. And I would hope that most advanced species think the same way.
If these desires turn out to be our downfall in the long run, then so be it. At least we died doing what we loved, rather than cowering in fear in our corner of the universe, waiting to be found and killed eventually anyway. But I guess that's just a matter of priorities, and it's fine if you disagree on that.
Thank you for your hard work in researching these topics, you put out the most interesting stuff!
Evolutionary biologist Ernst Mayr debated exobiologist Carl Sagan in the late 1990s. He argued, not that there was no extraterrestrial life, to the contrary, but that "intelligence" itself is a evolutionary dead end. After all, the only example of "intelligent life" we know anything about are Homo sapiens which have existed only a few 100,000 yrs. and already, compared to all the creatures on earth that have existed for millions of yrs, we're seemingly dedicated to our demise as well as the planet on which we reside.
Well, I'd argue we're also the product of all that 'evolutionary struggle,' we're just kinda neurotic about it right now. :)
I think this Ernst Mayr guy was full of crap. Plenty of species on Earth have unwittingly driven themselves to extinction throughout the ages. Our intelligence and adaptability might be the very thing that will save us.

And you are perfect example of what he just said, actually doubt there much intelligence to be found of you now that I think about it.
Well aren't you a little bucket of sunshine.☀️
Of all the proposed solutions to the Fermi Paradox, my personal favourite (if for no other reason than it's a most optimistic...and nerdiest) is the "Prime Directive hypothesis." The idea that perhaps an advanced alien civilization has known about us for a while and has been monitoring our progress for some time now, but by their own cultural laws are not allowed to make first contact or intervene in our development in anyway until with reached a certain technological, sociological or biological threshold. Like, maybe they want to wait until we get over this whole "waging wars and polluting the ecosystem" phase before they deem us ready to be invited into their Federation.
@@Name-cz5jj Thing about space is...it's big. I highly doubt there will be any resources in our solar system that won't be abundant everywhere else in the universe.
It does seem pretty cool...I guess. It's definitely not the most realistic, but, if anything, it just feels kind of rude. Can't they just help us out themselves instead of letting us all die? IDK
@@xiphactinusaudax1045 That's one major criticism levied against Star Trek's Prime Directive. But the thing is even within our own species the concept of "ethics" and "right and wrong" differ from group-to-group and even individual-to-individual. Who's to say an advanced alien race might not have an extremely complex and sophisticated set of "morals" and "laws" that to us seem cold or bizarre because they are literally alien to us?
Maybe they've tried making first contact with other civilizations before they were ready and it ended badly for both parties so they decided it's better to let a species figure it out for themselves than be partially responsible if things go wrong.
@@Name-cz5jj No, they could help them along the way. They are advanced, there's no reason they can't just ease into it and help them out. Who ever said that they would be getting technologies they aren't responsible enough to possess? There's many ways of going about contacting an intelligent civilization that wouldn't end badly
@@AceSpadeThePikachu But wouldn't it make more sense to come up with solutions to the problem rather than avoid the problem whatsoever? Isn't that how innovation occurs?
I'm not an advocate for METI (SETI is fine) however, instead of sending our location as a stationary point in space, (at the time of the transmission of the message), would it not make more sense to outlay our path in the universe for the next, say, 1,000 years? that way any recipient of the message could 'simply' check our stars path to find us, hopefully peacefully (hence my apprehension for METI)
Eh, fuck it, if they blow us up they blow us up, nothing we can really do about it.

There seem to be a lot of obvious process steps that never get mentioned in most of these videos. Either because they're so obvious that they can be taken for granted, or because they've been overlooked/brushed under the carpet by the teams who are proposing to send the messages. You decide. My list starts with: (1) "Radio" is really electromagnetic radiation, so where on the spectrum of potential frequencies are "we" broadcasting [why would aliens be looking where we're broadcasting?]; (2) is it aimed in the right direction to arrive at the targetted place at the right time after years of travel [already montioned by another commentator - it's pretty pointless aim where we see the target today]; (3) what is the message's duration [how long have the aliens got to receive it before it's gone past them]; (4) how many times is it immediately repeated [to allow for potential signal dropouts to be filled in]; (5) is it rebroadcast multiple times after some amount of delay [to demonstrate that it's not a fluke]; (5) if the target is close enough is anyone here listening for a possible reply; (5) how easy is it to decode [viz Nobel Prize winners need not apply]. There are doubtless many other issues that others could add.
1) my training and passion being electronics and radar.... the EM spectrum is pretty large, even when considering "radio" and microwave. From a physics standpoint, provided our local understanding of physics scales to large distances, we are broadcasting in ranges likely to be monitored by aliens that use anything similar to what we understand as technology. There is some possibility they advanced straight to magic as far as we are concerned, but if they understand electromagnetism half as well as we do, or twice as well, then monitoring the radio and microwave spectrum would be rather obvious to do, if you are looking for other aliens. A full explanation goes a bit beyond a YT novel, but suffice to say that we can monitor a very broad range of the spectrum using the same or very similar equipment with no major material processing hurdles. Things get a bit different when you enter the visible spectrum and the wavelengths start to intersect with metal grain sizes or sub-micron structures. That is when physics doesn't really change, but our models of what happens go through a very janky set of transitions to describe why bulk behavior doesn't continue down to the atomic scale.
As for whether or not they have the systems to decode the message... hopefully they are recording and can analyze it to start trying to make sense of it.
2) probably. Hard to know for certain, but even if we shot heavily collumated laser beams, the wave front spreads out enough that there's a rather high probability that failure to account for a systrem's movement would prevent them from intercepting. Basically, the wave trades amplitude (probability of detecting a photon per volume area/moment) for coverage (same number of die rolls, just more locations rolling spot checks).
3 and 4 .... going to have to ask someone who worked on it or studied it more than me. I would presume they had some kind of broadcast schedule and broadcast several times, possibly over the course of weeks/months.
We do have systems listening for things in general. There is a healthy chance we would notice if someone broadcast back. Though this assumes they would reply in kind. They may just hop in the proverbial car and come over to say hello. We, still back in the days of crawling on our stomachs, may not appreciate the growing show of people walking around.
5 ... the question about encoding.... (or was it six).... is a long, long discussion about math, assumptions fundamental to humans, theories on how aliens may think or structure information, etc.
You can bet that if we got a signal from another star which did not appear natural would have all manner of scientists and theorists pouring over it for clues on what it was and how to make use of it. To some extent, we have to presume aliens would be similarly attentive and be willing to search our signal for patterns or clues as to how to make sense of it. And be sure to leave enough clues and mathematical relationships in the structure to try and check our human intuition and let math do the talking.
We can't do much with aliens who see an obviously unnatural signal and don't bother to study it. There's no "give a damn" ray we can package along with it.
In all seriousness, it's all a bit of a long shot. But it's not like we are sacrificing large amounts of resources to toss a few radio signals out and see if anything comes back, either. If I gave you a ten billion sided die and said you could roll it as often as you want to try and get ten thousand ounces of gold... and rolling costs you nothing but a bit of attention... you would probably roll it a few times out of sheer curiosity.
@@Aim54Delta i understand what you saod and Immediately forgot everything i read, but was an interesting read 👍
And i would add to all of this:i think the life in the universe(especially intelligent life) is so RARE in the universe,and the universe is so VAST,that,we,as a species,will be long gone before something else catches these broadcasts or everything else the humanity sent into deep space.
@@Aim54Delta I like your points. I feel your 1 runs on many assumptions, given how meandering our path of science has been throughout history, and that we’re speaking of evolution on another planet with a different atmosphere and geological structure… I don’t think taking for granted an ease of developing a certain technology is very prudent…. To me that’s as much of a blind spot as believing your universal code could be understood by anyone, because you authored it, when even the brightest couldn’t figure it out.
For 2, I love the physics, yet we’ve only practiced and interpreted them in our little bubble out here on the edge. I feel a simpler explanation could assist your points too; tracking orbital movements is an ancient science and to suddenly not account for trajectory in sending a signal doesn’t follow the current model. Unfortunately, because we’re in that bubble we don’t really know how our signals may degrade.
I would also add, I feel it’s also a bit presumptuous to assume any pattern to repeat a signal would be perceived by extraterrestrials as an intended signal. Have we ever tried deciphering a repeating signal (:edit: from outside our bubble) after discovering it’s machination? Why would they?
Great comment. Since we don’t see any information in space that leads us to believe there is nothing out there but we know there must be them maybe intergalactic space is not following our rules of electromagnetic radiation. Maybe dark matter is essentially erasing the information. Or just coding it in a way we haven’t learned to read or even look for yet. We are so primitive that we can’t even explain light or gravity yet. We are only a few hundred years into this new era. Time will tell us many new and amazing things. I have no doubt about that.
After watching the latest KurzGesagt video and reading the Three Body Problem i'm not so sure we want to be sending messages out there !
I think it's incredibly naive for us to think we can communicate with aliens when we can't communicate with a single other species *on earth*...
Edit: Lots of people in the replies saying that "we can train animals to communicate" are entirely missing the point... First, you aren't "communicating" with your dog because you can tell when they want walkies. Second, we aren't talking about the domestication of a known alien species. We are talking about sending a disc with some scribbles on it into unknown species territory and expecting them to have the intelligence and sophistication to understand *extremely* foreign languages. It's like trying to train a dog by throwing flash cards at them...
Domestication of animals is a long and arduous task, your dog is bred purely to be domestic and still it's a struggle sometimes...
The only arguments I see for aliens understanding our language are:
1) "*Intelligence* was made in the image of God, not just man." Meaning all intelligence in the universe was seeded by a common ancestor and that language develops the same regardless of external stimuli. Why would life, separated by lightyears, evolve so closely as to develop language structures similar enough to understand? (Just look at how different written English is to something like hieroglyphics, and that's *only* separated by time; Compare it to Cyrillic for a space seperation. And now multiply both these dimensions by orders of magnitude...) The only answer I've heard is "intelligent design". But seeing as we made pugs and poodles out of wolves and dingos; Either evolution is real and susceptible to influence, or all actions must be preordained by "God". Which in itself is a logical fallacy as it's a completely unprovable appeal to authority that sets up another unanswerable question; If there is no freewill in existence, no chaos in the universe, why is everything?
2)They are so far advanced in there cryptography that they can decipher completely alien code. If this is the case and we are in proximity to get a message to them, they know we exist and have chosen not to communicate. It makes no sense that they have the technology and intellect to decipher our message (which many of our own scientists, who have much common knowledge, couldn't do) but don't have the technology to reach out to us in a more acceptable language.
We can communicate with other species in as much as they are willing and able. My dog and I communicate at the level he is capable. We have established norms and can convey needs, commands, warnings, emotions, etc. Granted we both know the other one can see and hear. If my dog was smarter then we'd communicate even more. Sure, he was bred to care what I do, but other non-domesticated animals can communicate similarly...they just aren't predisposed to care as much about what man does if it isn't survival related.
We are also the only technological civilization on earth, so....
We also domesticated plenty of animals and even changed their genetic makeup to suit our desires (dogs and cats)
I hope you've read at least some Ted Chiang short stories, he deals A LOT with language and communication. But one of his stories is precisely about this (communicating with other species on earth), it's called The Great Silence. It is in his collection called Exhalation: Stories.
We're trying to communicate with intelligent aliens. There's only one intelligent species on Earth, us.

"If we're not in, please leave a message"
I've seen a lot more concearn for the Dark Forest theory expressed recently (probably from Kurzgesagts fantastic video about it) and I'd like to add something I really hope everyone keeps in mind.
Picture a super-advanced, entirely genocidal race of beings; powerful enough to make the whole galaxy look devoid of any intelligence, except for us, who they haven't found yet.
So why would we even be here? If their urge to purge is so absolute, why even wait for other intelligence to develop in the first place?
Let's say this super advanced, genocidal civilization detects primitive radio messages from another star. Given the timescales of interstellar travel, they know that any fleet they send there won't be arriving to a primitive civilization. In all likelihood they have a multi-thousand year long voyage ahead of them, so if the original senders of the message don't wipe themselves out, then there is easily enough time for them to progress to the same (or even greater) level of technology as the inbound fleet, given they already have radio by the time the fleet first departs. So how does the super advanced civilization solve this problem?
They don't wait.
They look for any planet with any kind of biosignatures (or even potential for habitability), and they send a probe to dismantle it ASAP.
This is perfectly in line with the logic of something so aggressive as what the Dark Forest hypothesis suggests. Because if they ever detect radio signals, then they'd know they're already fucked. In all likelihood, they would now already share the galaxy with another monsterously powerful, incomprehensible, multi-headed super organism. And they know it will eventually learn what they've been up to.
From this you could potentially have a 'Dawn Forest' Fermi-paradox solution, in which this scenario did actually play out in the Milky Way, except the super predator civilization recently faultered, and subsequently got it's ass kicked. Only just now would intelligence like us have a chance to get going again naturally. Perhaps most of us aren't advanced enough to detect one another yet, and the galaxy still looks very empty.
Considering that Earth has had detectable oxygen for the last few billion years, and nothing in all that time has wiped us out, I think we're ok. Anything that could come and destroy us before we're advanced enough to fight back would have probably already been on it's way here long before we invented radio.
The dark forest theory has been popularized by The Three Body Problem series of books. The second book in the series is literally The Dark Forest.
You have way to much time on your hands.
@@esquare807 , no, it's you who has to much time. Because he used his valuable time to tell us some substantial and reasonable. But you waste your time to write short but compltetely useless non-content.
@@holdinmuhl4959 Hey now. I do really appreciate the support, though I think E Square was being sarcastic or semi-serious.
Btw E Square, time is a meaningless concept in the pit that is the TH-cam comment section. 3 hours spent writing an argument to "no u" is a warm-up for almost anyone you find here.
The dark forest hypothesis parts from the false premise that intelligent species would "compete" for anything in the galaxy: Space, resources, etc. But in reality the need to compete for any of those things may be non-existent. Our stellar vicinity alone contains more real estate and more resources than the human civilization would ever hope to consume. Combine that with the fact that more advanced species will most likely be more efficient and consume less resources than any of our estimates, and there is no reason for any aggressive civilization to exist, let alone spend their time fighting any potential "competitor" in the galaxy. Space is too empty and too big, and the galaxy contains so many resources, they may as well be unlimited. Hypothesizing about extraterrestrial politics by drawing comparisons with the history of humanity assumes many false premises. Extraterrestrial civilizations will not share one planet with non-renewable resources, to begin with, and space is more difficult to travel than any ocean.
Maybe they would have ideological reasons to expand aggressively and attack their neighbors without provocation, but not for resources or territory, and the chances of such civilizations to exist and survive for a reasonable amount of time are very low.
Let's definitely send GPS out in space to a potentially more advanced species and let them know where to come wipe out the competition.

Anton, that's awesome!
Why don't we just send out a unique signal that repeats every 20 seconds (like the first 60 numbers of PI or the like) an transmit it at different frequencies. That's what SETI is looking for.
It's because the beacon transmiting this signal would have to be extreamly powerfull, if you want your signal to be detectable on significant distances. Building such a thing is a waste of time. We know that there is nothing in our neighbourhood, so we would have to reach further, and then time comes into play. Nobody is going to wait for hundreds of year in hope that someone will reply to a signal sent millenia ago, on random frequencies hoping that someone is actually listening. All the resources we waste on SETI should be allocated into developing and building powerful space telescopes, because they potentially can detect biosignatures, and if they do, we've got something to work with. And even if they don't, they will discover a bunch of other thing, so it's not a waste.

The more advanced society becomes, the more we integrate ourselves with nature around us, instead of trying to change nature and the more we try to become quiet instead of loud and obnoxious.
And the fact that communication through gravitational waves is a thing now, and quantum communication.
Who are you to say there is nothing around us, our neighbourhood might be thriving with lives for all we know, we just cannot hear or see them since our technology right now is basically in its infancy, its only 100 years since the electronical computer was a theory in paper. And only 80 years since it was built in theory.
@@SMGJohn Gravitation waves communication? Mate, Less sci=fi more science. We can barely detect them at present, and it takes a catastrophic event like neutron star collision for us to even hope to detect something, not to mention creating them to communicate on interstellar distances. Same with quantum teleportation (i assume that's what you meant, as quantum communication is basically an idea to protect data you send) - no information is being sent as superluminal speed, so yeah, you're talking nonsense i'm afraid.
Obviously, there is a possibility that some laws of physics exist that allow these things, but we yet have to discover them. But at the moment nothing really indicates that that's the cases, so we should stick to what we know and to methods that actually produce meaningful results. SETI and similar programmes have nothing to show for, despite years of trying, so all the resources should be allocated somewhere else.
@@SMGJohn when you watch interstellar once
@@tomekkruk6147
What? I am telling you that we do not fully understand everything and aliens might try to avoid beeping out radio signals left and right to begin with, communication through radio waves is extremely energy consuming and not to mention the time delay is irrational for space com.
Whatever they are using, has almost no delay over vast distances, is not detectable by little children like humans playing in a sandbox with technology thats probably thousands of years behind anything thats remotely intelligent enough to travel between star systems.
And even if there were civilisations on equal terms of us, we would been able to detect changes in the atmosphere from their activity, something we have not yet been able to do apart from a few anomalies here and there that are not well explained and could equally have natural explanations just as much as the alien one.
Sorry to know that you lost your dear child. He is in Heaven at Eternal Peace.
I never thought about self reflection giving such insights. It's possible, but I think humanity's inhumanity needs to be reigned in first. Gives me hope to think about that though, thanks Anton.
I’m with Hawking on this. Let’s keep our trap shut until we know the aliens aren’t malevolent.

@@theluftwaffle1 Yeah i read this and thought: we have no fucking clue who's listening. Just think about what we are capable of and add intergalactic travel n shit...

Now imagine if something like the BORG is out there.
I disagree. Any species with the ability to travel interstellar distances will have secured the technology to detect us millennia ago. This is a great way to reach any potential neighbours and declare "We're here, we're friendly, we just want to talk".
Of course, our best current understanding of the situation is that we are alone. We might be the only intelligent life in the Milky Way.
It would seem that the only signal that could be received and make sense to an alien civilization would be a binary signal, Morris code if you will, in which we tap out prime numbers. Otherwise how could any alien civilization possibly understand how to interpret different codex that we have created for sending images? Always great to watch your videos!

I read a short story where aliens came to Earth after a global ice time had wiped everything out -they find a strange can with a roll with a long strip of images. Their scientists find out that if you play the pictures after each other in a fast progression it creates an illusion of motion. They play the images and become really confused by all the strange things it shows especially the series of symbols that ends the whole thing and becomes a riddle for the scientist for the years to come -the words "Walt Disney".
Name of the short story? :o
I don't remember the title. I saw it in a short-lived magazine back in the eighties. It's possible it was written by Arthur C. Clarke but I'm not sure.
We should send the message “26” in binary to indicate how many letters we have, then give binary equivalents for each letter and a good bit of numbers. Then say: “we are sentient. We are here.” Hopefully that is enough, in binary and Morse as image and sound
Except different common languages have different alphabet lengths.
I wonder what we would do if we one day build a telescope able to see other solar systems in detail and what we see is a telescope looking back at us.

The Dark Forest. 'nuff said. Thanks as always Anton!
I think the main point of the original message was to have fun putting symbolic meaning into something that is really mostly about designing a message that “looks” distinctly artificial. I’m curious how the messages were modulated
Harrumph!
I have two serious issues with deliberately sending messages:
1) It's a really, really, really, bad idea! Made worse in providing a return address. Do I have to explain why it's such a bad idea?
2) For any individual or group to take it upon themselves to send a message to the stars on the behalf of the human race is the very definition of hubris!
Does a radio signal travel to the target planet and pass by (needing a civilization there at the moment it passes by to receive it) or does it stay there forever?
Passes right on by. That’s why it’ll never work as a non repeating signal. The chances of timing it just right in the grand scheme of the things is just not plausible imo.
The way he explains stuff is so easy to understand
I heard that scientists beamed into space a recording of John Lennon's song, 'Across the Universe.' Pretty cool.

I like to think there is an alien Carl Sagan out there searching the stars, too.
@@striker851 hmm yeah. But at a point we have to think about how when it comes to aliens our logic and representation become subjective. I would say that they need non scientists on that team, because of the nature of thinking required.
Like if I was an alien species looking out for life everywhere then any narrow band signal with patterned pulses maybe showing a temporal, spatial location of earth using hydrogen would spark my interest, maybe they are also assuming hostile species but giving them more info is detrimental to us, like hey these are our weaknesses come kill us.
And maybe just what humans look like. Like the japanese scientist did.
Would you consider doing an interview with Dr. Becky Smethurst from Oxford? I bet you two could do 90 minutes just on black holes alone.
Honestly, the idea of sending messages is almost pointless because there are so many things that need to be just right. The astronomically low chance that something actually picks up on a message, most non scientific people/ aliens would have no clue what they're seeing and would most likely discard it. The thing that we need to focus on is more non-natural shapes. If we show something that must be unnatural, they are going to take it serious and not discard our message. Much like the WOW signal we got, we still have no real answer to it and it is something that is brought up all the time.
Being said, while sending messages is almost pointless, it does have value; just on the off chance, just maybe, somewhere, somehow, something will pick it up.
Thank you Wonderful Person

If the answer to the fermi paradox is the dark forest hypothesis we are screwed
They already answered back and visually left [crop circle] of the Silica molecule as new human basis of life.
Broadcasting our existence, level of technological achievement, and location, seems to me about as wise as walking through the bad part of the city at 2am, carrying an enormous, heavy bag with a dollar sign on it, and leaving breadcrumbs in the form of dead presidents. That is, it seems very unwise.
Not really
If aliens can do harm to us they can sterilize planets so that life cannot even appear, they also have bigger telescopes and are generally more advanced so they could detect our radio signals that we use for communication
Imagine they watch John wick
Such messages are like mosquito buzzing, they only prompt real universe powers to end us with one move of "hand". We are stupid mosquitos... .
You have COMMON SENSE MAN!!!!! One of few in this thread....
I say let´s focus on try to receive THEIR messages first instead of trying to give them our location, strategic enhanced
Repeat the Fibonacci sequence 1, 1, 2, 3, 5, 8, 13, 21 in simple pulses of energy in multiple frequencies and at different rates in a cycle. Then they can easily detect and confirm that they are seeing a signal.
Sending out these kind of messages can be very dangerous we don't know what is out in the universe and we are just sending out messages 😤😤😤
I agree with Steven Hawking on this.
Best to keep silent in a jungle.
If the microcosm reflects the macrocosm.
I'm afraid aliens will be dazzled by our animal life and start raiding us as a pet shop
there's no way to hide in space. we can't block our transmissions and if we could there should be an IR signal showing something is odd. if you have a species out there capable of doing anything about our messages there are some safe assumptions.
first, we can assume there is a logic to their actions because they would need advanced logic to make any kind of communication.
second, we can assume that they have some form of cooperation that allowed them to build technology, which implies compassion or at least some kind of value system.
third, we can assume that they don't have either or both the ability or the desire to conquer the galaxy because if they wanted to and could they would have done so already. it's not hard for a k2 civilization to use their star(s) to sterilize every rock in the galaxy and wouldn't take long on cosmic scales to colonize every star in the milky way at sub-light travel times.
fourth, we can assume that any extraterrestrial intelligence would evolve some kind of sensory perception, and if they have technology they would use it to interpret things they cannot perceive. if not for curiosity's sake then for science, defense, or just because they can.
they're going to be very different but will certainly have commonality with earthlings. if i, an octopus, can learn to think and write in human, humans can learn to think and wrote in extraterrestrial.
Space is wast very very wast

No reason to worry about sending messages when the entire planet is projecting "here we are" like some kind of car dealership at night with those giant lights seen for miles away. Heck could just ignore radio and just point a telescope at earth and detect phosphine, methane, oxygen.
Might be an idea to send Morse code alphabet. Then send same message in Morse code in a couple different writing type of language. On repeat to various areas. If they can pick up radio, they might figure out some simple messages. Or linear message that shows initial different tone for arrow direction, that shows our Sun and planetary system. One type of radio pulse for a while to say straight, one to determine left and one to determine right. Messages can be sent in the form of pictures using three different radio pulses. Like drawings where as the pen is never lifted off of the paper. Very simple and basic.

While it's fun to imagine an alien civilization receiving an old I Love Lucy episode and having a "wtf" moment, the reality is that most of those radio and TV signals lack the power to propagate very far once they leave Earth. By the time they reach the Kuiper belt, much less another star system entirely, most of those signals will be barely discernable above the background noise of the universe.
If they're more advanced than us, then it's more likely they will detect our atmospheric composition and determine that life exists here -- possibly even technological life if they can detect certain artificial compounds in our atmosphere.
