12:41 that's not impossible to imagine. We've sent one off signals ourselves at random stars just hoping for a reply. I can imagine an alien civilization receiving a wow signal from us and not knowing what to make of it.
That’s a great point. We always seem to assume that other intelligent life-forms are infinitely more organized and competent than we are, or we forget, like you say, that we might look like bumbling, belligerent bumpkins. Actually, uh, I think I made both profiles sound dead-on target.
The issue isn’t when they’d emit one offs but whether we’d detect them. It’s incredibly improbable that Big Ear would have swept across that precise correct position at the exact right moment to observe it.
@@Graeme_Lastname yep, it’s the scientific method. If you discovered something outstanding but cannot repeat or replicate it the scientific community tends to look down on it. A good example is cold fusion.

You make it interesting by sounding interested, yourself, which again I'm sure you are, but nobody can be that passionate 100% of the time. Life makes sure of that. so good job!

Maybe the WOW project was just getting started when the Alien's version of Congress, in a cost-cutting measure so they could give massive tax breaks to their ruling class, cut "unnecessary and unproductive scientific projects", which shut the project down! (sarc!)
This probability all depends on how focused the antennas are and as well as how focused the signal is. Say both sides are tightly focused, then chances of catching a repeat signal is very very small. Good example would be like going up in an small airplane to the ocean looking for someone missing out at sea. You take your camera with telescopic lens and scan record the ocean looking for that missing person. After a full day of searching, you review your video and find that at 2:37pm there is a very clear pulse of flash coming from some part of the sea. Seems likely it was that missing person floating aimlessly and desperately flashed the plane with a mirror. The next day you desperately fly back to where you guess that spot was, and scan again with your telescopic lens. What's the chance with a telescopic scope like lens looking for that missing person will you spot him? And what's the probability he'll be able to reflash his mirror to you just in time for you to see? Now the universe is way bigger than the Pacific Ocean and everything is in motion as well Just a few micrometers off and you are scanning a different area of the universe by milions of miles.

Made me imagine a transmitter out in the unfathomable distance, going on and on, sending signals at certain intervals for ages before it ceased to function, and the Wow signal was its final pulse. We caught the last (at least from our perspective) whimper of a long-gone species, and we can't even recognize it as such, because we are unable decode it.
Thanks Alexander - Ye we know it, the actual specific star from this signal originated isn’t really relevant for the discussion of repeatability though
I recommend you check out the recent statements by the Pentagon stating the fact that they have in their possession crashed vehicles from another planet.... And has released the videos just recently of alien spacships visiting our planet right now
@@thehassaankhalid because you don't listen. It's a 95% chance to catch a repeat in that timeframe, leaving a 5% chance that you missed it, 5% aka 1/20. Makes perfect sense. 5% obv being the complementary probability of 95%
Aliens:”just send them a powerful narrow band signal… should it repeat?…. Why? If they’re listening, they’ll get it the first time, no need to repeat it”
It's not at all a science facts channel. It's a space related facts, philosophy and discussion channel. It's very specifically space, which is only a part of science, obviously. And it's very much not a "leaning about science facts" themed channel, that's a very different kind, like SciShow. This really shouldn't be hard to understand, or define. It's clear and simple. You've only managed to show idiocy with your comment.
I can already imagine this video being made by an alien talking about the arecibo signal. Or maybe on an extremely rare case both species, us and them, one recieving our signals and us recieving theirs, both doubting if the other exists.
You sir are a great communicator. An interesting follow up video would be on how a civilization might set up a repeating beacon of their own. Something that, presumably, would last past their civilization.
A shame in the context of "Black Swans" it is neglected that several pulsars had been detected well before CP1919 by persons that were not allowed to publish due to national security, or for that matter had been visually noted by observers in the 40s but those observations were dismissed.
F yeah Event Horizon has the best video on the WOW! signal; JMG's personal interest and curiosity on the subject is phenomenally contagious. Great shout out.
I agree, I love Astrum & Cool Worlds. They're two of 12 channels I'm subscribed too. I just vehemently disagree with Alex on his views on SETI, more specifically, Fermi's paradox. For starters, an advanced alien civilization isn't going to be using radio to communicate over vast interstellar distances. It's ridiculously insecure to begin with (even encrypted, anyone in the broadcast path will be able to have a general idea of where it came from), but perhaps most importantly, it's insanely inefficient (read: inverse square law, SETI's kryptonite) - an advanced alien culture will be an efficient one so it won't be using radio, that would be like us using smoke signals. Heck, we lowly humans have already begun moving away from radio to lasers to communicate with our satellites in orbit due to the increased bandwidth it offers. Fun Fact: Our terrestrial radio signals (signals meant for consumption here on Earth, think FM/AM, TV, Cellular, etc) don't ever leave our solar system. Thanks to the inverse square law they become background noise before they even get close to leaving our solar system.
i agree the biggest admission from government in humanity's history = and he is still faffing on about the wow signal ....we should shut seti down and search earth because they are already here
@@Bitchslapper316 cos u can see it yourselves .... you scientists are all deep rooted athiests lol ...wake up If ET knocked on your door you would go back to bed and call it a dream ... the pentagon admitted the footage is real so why keep searching out there when they are already here ?
You have of course seen Jim Benford's latest paper on the subject? He suggests that the Wow! signal is non-repeating, caused by our catching a random fragment of overspill from a microwave power beam used to drive a sail spacecraft.
Yes! I have a lot of thoughts on that. I think if it truly were non repeating then the chance that Big Ear looked at the right moment in the right place is so minuscule to the extent that I would reject the hypothesis. However, I think really he might just mean non-periodic, sporadic leakage, which means over some time frame it will happen again and then it’s really not different from an intermittent beacon.
You know, now that people are more seriously looking into concepts like Starshot, it might be possible to run a simulation to see how likely that circumstance is (ie would the beam overspill a lot or only very rarely? would the overspill only be as direct radiation aimed at the target star or would it refract off the edge of the sail enough to be visible to other nearby stars? etc)
Shouldn't we calculate it based on the total amount of time that _any_ radio telescope has observed that region, not just Big Ear? After all, there is nothing special about Big Ear. It's a bit like calculating the chances that a specific person will be hit by lighting, which of course will be very very small. But in this case we don't care what the chances that some random person specifically will be hit by lighting are, but that _anyone_ would be hit by lighting. That any detection of the Wow! signal would be made. It doesn't matter if it's Big Ear or someone else. It has to be _a_ telescope but there is no predetermined significance as to which telescope that happens to be. So shouldn't we calculate based on how long _any_ radio telescope has observed that region instead of just Big Ear?
Laymen question: Are there black swan events in geology that would speak to the statistics methods, or even evolutionary biology ? Maybe I should check greatcourses for any series on statistics, but it bugs me that we can model probabilities for N=1 events, especially with scales being unknown. Loving the vids as always, seems a fine balance between inspiration and skeptical prudence but the cool worlds studio/team/why seems to nail it.
The LIGO GW150914 detection occurred only months - not even a year after resetting the instrument. A 0.2 second event. That seems almost as improbable as the Wow-signal.
I've often wondered if the WOW signal was artificial, perhaps the reason its not repeatable is because its not coming from a fixed point in space. Perhaps it was transmitted from a moving spacecraft traveling through the galaxy. So looking in the same region of space its no longer there. As the transmitter has perhaps moved on but i guess we may never know. Great videos cool worlds 👍🏻
It may also be, that the beacon is stationary, but directional, only sending the message towards a very specific angle at each repetition. If that's the case it might be years before "our" direction is pinged again (considering the other civilization might target every single one of their known stars before they get back to us). A reason to do this could be that they need to use a very high energy transmission to even expect to reach us (or anybody), if e.g. they're even further away than we ordinarily would expect.
Did not tune in to learn the extensive history of Black Swans, and the meaning of the term is pretty apparent. Tuned in to see if you had any actual info about the "Wow" signal.
This approach seems similar to determining the decay rate of a proton, or to determine if it even decays at all. I guess the twist is that the lack of a data point may tell us more than if we had a just a single data point.
What about a signal that is constantly sent out straight out in the sky in a narrow beam from a planet orbiting around its star? In that case on a far distance you have a very small window in which you can detect the dignal. To know when you can detect it again you ‘only’ have to know the planet it came from and its orbit data. What I’m trying to say here is that we might just have been extremely lucky and that the planet might have a very long orbit.
I don't fully understand the physics behind the signal but aren't you discounting another, very real possibility? That the signal was not intentionally aimed at us, and happened to reach us due to some incidental maneuvers of an alien ship? It would still be an unlikely event that we happened to be pointing there at the time, but unlikely events DO happen.
The purpose of the signal is not assumed to be of a specific form here. It could be a comm, it could be leakage, it could be accidental. It doesn’t actually matter. It was a ship, over time more maneuvers would be done given sufficient time and it would again occasionally leak our way, so then it’s in fact no different from an intermittent beacon.
If Milky Way has 3 billion stars approx, then 0.3% would actually be a huge amount of pulsars dotted around in our own galaxy (9000000 aka 9 millions perhaps?) which is absolutely fascinating.
We'll never be able to decode it if so, unfortunately. It was not recorded. The signal was in the form of intensity variations in radio waves at a specific frequency. We only know that, the intensity of them.
So interesting! I love these videos and papers from Cool Worlds. A very good format, level of details, and explained in an excellent way! Looking forward to the next upload. I'm staying curious.
I watch this video from start to end, yet understand nothing. I just pretend I do, and thats what makes it interesting. I cannot even memorize the multiplication table.
I'm skeptical that this was down to alien intelligence. I think that it was probably either created by man made interfierance somehow or a mal functioning receiver. Or possibly natural causes as a result of a rare situation of multiple elements in space coming into contact with each other and giving off a short radio signal as a result.
That's a great point about hot Jupiters. I also wonder if silicate life is possible, we might find it in the mantle. Having a shadow biosphere which may possibly be larger than the one on the surface.
I feel that a great thought experiment in this context is how would you transmit such a signal? May give some clues on intervals to expect. However, just gathering as much data as possible is a better method to be fair. Have to have some sort of balance between clever methodology and brute force methodology.
Trying to guess how or why an alien civilization would do something is rather pointless. We've only truly been technological for about 100 years ourselves, we truly have no clue what an advanced technological civilization would be like. I expect 99% of what most people talk about (O'Neill cylinders, traveling through space as biological beings, etc) are probably very wrong and unlikely. Besides the how is much less important than why a civilization would send out signals. And we really have no basis for even guessing at alien psychology. So best to just do much, much better at listening and see what we can here.
1974, the Arecibo telescope send the most powerful broadcast ever deliberately sent into space. We are now visible in the distance of 47 light years ^^
Can the frequency of expected signals detected happen without considering the only example we have of high-powered transmissions from an intelligent civilization, namely, us? If that transmission took the form of something like the Arecibo message, how does that affect the probabilities?
I have dyscalculia too and I can say that it wasn’t until 15 years ago that somebody laid things out in this manner that things changed. Dr kipping nails it every time I
I've replied to this comment a few places elsewhere but the point is that such a signal is inherently incredibly unlikely to be detected, since it demands an short-duration signal (~ of order minutes) to be sent out way once in *all time* that we just happened to be looking towards at the right place and at the right time (the odds are genuinely astronomical)
Oh the irony LOL.... We're talking about this about signals from millions of Miles away distant Stars and such.... And the aliens are here and have been busy with us for hundreds of years.... And actually just recently the department of defense of the United States of America has released videos of aliens spacecraft.... They even stated the fact that they have unearthly vehicles that have crashed here they have in their possession right now.... It's funny huh the irony is killer...
@@christopherfields2015 Its definitely possible. physicist michio Kaku was just suggesting that. If ETs exist, they likely travel in digital form by lasers, and occupy 3D-Printed bodies, and blend in with the people on the planet they are visiting

Makes perfect sense. 5% obv being the complementary probability of 95%
Aliens:”just send them a powerful narrow band signal… should it repeat?…. Why? If they’re listening, they’ll get it the first time, no need to repeat it”
Cool World is the best channel for learning the most Interestingly wonderful science facts.
He explains it in a way that everyone can grasp………..
It's not at all a science facts channel. It's a space related facts, philosophy and discussion channel. It's very specifically space, which is only a part of science, obviously. And it's very much not a "leaning about science facts" themed channel, that's a very different kind, like SciShow. This really shouldn't be hard to understand, or define. It's clear and simple. You've only managed to show idiocy with your comment.

I don't understand how you can make any determination on when the next "black swan" event would be when you are working with a data point of one.
Even horizon knows a ton about Wow! Thank you for mentioning him!
I can already imagine this video being made by an alien talking about the arecibo signal. Or maybe on an extremely rare case both species, us and them, one recieving our signals and us recieving theirs, both doubting if the other exists.
You sir are a great communicator. An interesting follow up video would be on how a civilization might set up a repeating beacon of their own. Something that, presumably, would last past their civilization.
Check out the Cool Worlds video on ancient alien civilizations.
as a west australian with a black swan tattoo I can confirm we are all anomaly's that exist but shouldn't
A shame in the context of "Black Swans" it is neglected that several pulsars had been detected well before CP1919 by persons that were not allowed to publish due to national security, or for that matter had been visually noted by observers in the 40s but those observations were dismissed.
F yeah Event Horizon has the best video on the WOW! signal; JMG's personal interest and curiosity on the subject is phenomenally contagious. Great shout out.
I agree, I love Astrum & Cool Worlds. They're two of 12 channels I'm subscribed too. I just vehemently disagree with Alex on his views on SETI, more specifically, Fermi's paradox. For starters, an advanced alien civilization isn't going to be using radio to communicate over vast interstellar distances. It's ridiculously insecure to begin with (even encrypted, anyone in the broadcast path will be able to have a general idea of where it came from), but perhaps most importantly, it's insanely inefficient (read: inverse square law, SETI's kryptonite) - an advanced alien culture will be an efficient one so it won't be using radio, that would be like us using smoke signals. Heck, we lowly humans have already begun moving away from radio to lasers to communicate with our satellites in orbit due to the increased bandwidth it offers. Fun Fact: Our terrestrial radio signals (signals meant for consumption here on Earth, think FM/AM, TV, Cellular, etc) don't ever leave our solar system. Thanks to the inverse square law they become background noise before they even get close to leaving our solar system.
What are your thoughts on all these ufos and the admissions from the pentagon?
He already uploaded a video year ago regarding this matter.
@@realbabychad There is new stuff out there but it's still premature to speculate on it. We will probably have a lot to talk about by mid summer.
i agree the biggest admission from government in humanity's history = and he is still faffing on about the wow signal ....we should shut seti down and search earth because they are already here
@@byromtaylor6482 Yeah but there hasn't been any admission so why should we stop talking about what we know.
@@Bitchslapper316 cos u can see it yourselves .... you scientists are all deep rooted athiests lol ...wake up If ET knocked on your door you would go back to bed and call it a dream ... the pentagon admitted the footage is real so why keep searching out there when they are already here ?
The wonder and curiosity you have is epic. 😮❤
You have of course seen Jim Benford's latest paper on the subject? He suggests that the Wow! signal is non-repeating, caused by our catching a random fragment of overspill from a microwave power beam used to drive a sail spacecraft.
Yes! I have a lot of thoughts on that. I think if it truly were non repeating then the chance that Big Ear looked at the right moment in the right place is so minuscule to the extent that I would reject the hypothesis. However, I think really he might just mean non-periodic, sporadic leakage, which means over some time frame it will happen again and then it’s really not different from an intermittent beacon.
You know, now that people are more seriously looking into concepts like Starshot, it might be possible to run a simulation to see how likely that circumstance is (ie would the beam overspill a lot or only very rarely? would the overspill only be as direct radiation aimed at the target star or would it refract off the edge of the sail enough to be visible to other nearby stars? etc)
Shouldn't we calculate it based on the total amount of time that _any_ radio telescope has observed that region, not just Big Ear? After all, there is nothing special about Big Ear.
It's a bit like calculating the chances that a specific person will be hit by lighting, which of course will be very very small. But in this case we don't care what the chances that some random person specifically will be hit by lighting are, but that _anyone_ would be hit by lighting. That any detection of the Wow! signal would be made. It doesn't matter if it's Big Ear or someone else. It has to be _a_ telescope but there is no predetermined significance as to which telescope that happens to be.
So shouldn't we calculate based on how long _any_ radio telescope has observed that region instead of just Big Ear?

Very nice channel! 😃 Great find. Thanks
Laymen question: Are there black swan events in geology that would speak to the statistics methods, or even evolutionary biology ?
Maybe I should check greatcourses for any series on statistics, but it bugs me that we can model probabilities for N=1 events, especially with scales being unknown.
Loving the vids as always, seems a fine balance between inspiration and skeptical prudence but the cool worlds studio/team/why seems to nail it.
Funny thing is: the few messages we sent to other planets didn’t repeat either
I would resubscribe to Great Courses Plus if you had a course on there.
Agreed! Cant believe your post hasn't gotten a thousand thumbs up.
The LIGO GW150914 detection occurred only months - not even a year after resetting the instrument. A 0.2 second event. That seems almost as improbable as the Wow-signal.
I've often wondered if the WOW signal was artificial, perhaps the reason its not repeatable is because its not coming from a fixed point in space. Perhaps it was transmitted from a moving spacecraft traveling through the galaxy. So looking in the same region of space its no longer there. As the transmitter has perhaps moved on but i guess we may never know. Great videos cool worlds 👍🏻
It may also be, that the beacon is stationary, but directional, only sending the message towards a very specific angle at each repetition. If that's the case it might be years before "our" direction is pinged again (considering the other civilization might target every single one of their known stars before they get back to us).
A reason to do this could be that they need to use a very high energy transmission to even expect to reach us (or anybody), if e.g. they're even further away than we ordinarily would expect.
Thanks, Excellent spending time watching the videos. I feel very good
One of my favourite YT channels. Thanks 🙏🏻👌🏻☄️🌎🪐💫☀️🌌🕳
Did not tune in to learn the extensive history of Black Swans, and the meaning of the term is pretty apparent.
Tuned in to see if you had any actual info about the "Wow" signal.
I like the story arc you manage too span while presenting the story of (your/an) actual paper.
Cool Worlds somehow got overlooked for binge watching - good job I'm not in charge of any surveys
This approach seems similar to determining the decay rate of a proton, or to determine if it even decays at all. I guess the twist is that the lack of a data point may tell us more than if we had a just a single data point.
What about a signal that is constantly sent out straight out in the sky in a narrow beam from a planet orbiting around its star? In that case on a far distance you have a very small window in which you can detect the dignal. To know when you can detect it again you ‘only’ have to know the planet it came from and its orbit data. What I’m trying to say here is that we might just have been extremely lucky and that the planet might have a very long orbit.
I don't fully understand the physics behind the signal but aren't you discounting another, very real possibility? That the signal was not intentionally aimed at us, and happened to reach us due to some incidental maneuvers of an alien ship? It would still be an unlikely event that we happened to be pointing there at the time, but unlikely events DO happen.
The purpose of the signal is not assumed to be of a specific form here. It could be a comm, it could be leakage, it could be accidental. It doesn’t actually matter. It was a ship, over time more maneuvers would be done given sufficient time and it would again occasionally leak our way, so then it’s in fact no different from an intermittent beacon.
If Milky Way has 3 billion stars approx, then 0.3% would actually be a huge amount of pulsars dotted around in our own galaxy (9000000 aka 9 millions perhaps?) which is absolutely fascinating.
Love your uploads.
The "wow signal" was another hunter in the dark forest who angrily shouted to us that we should finally put out our campfire.
Have you considered auditioning to be a James Bond or Bond Villain? Got the voice, charisma, looks, smarts
I can see him being a relatable supervillain who the audience is secretly hoping succeeds in his schemes.
Lol.If I remember right, Stephen Hawking suggested himself for the same role.
I always thought: what if the wow signal was a warning but we cant decode it. And by the time we do itll be too late.
We'll never be able to decode it if so, unfortunately. It was not recorded. The signal was in the form of intensity variations in radio waves at a specific frequency. We only know that, the intensity of them.
you just described the Remembrance of Earth's Past book trilogy
Good job recommending John Michael Godier's channel! It's well worth a watch 👍

I think the interview with Kaku a couple weeks ago was pretty good.
Fascinating approach to this subject. Good stuff
So interesting! I love these videos and papers from Cool Worlds. A very good format, level of details, and explained in an excellent way! Looking forward to the next upload. I'm staying curious.
I watch this video from start to end, yet understand nothing. I just pretend I do, and thats what makes it interesting. I cannot even memorize the multiplication table.
I'm skeptical that this was down to alien intelligence. I think that it was probably either created by man made interfierance somehow or a mal functioning receiver. Or possibly natural causes as a result of a rare situation of multiple elements in space coming into contact with each other and giving off a short radio signal as a result.
That's a great point about hot Jupiters. I also wonder if silicate life is possible, we might find it in the mantle. Having a shadow biosphere which may possibly be larger than the one on the surface.
'Black Swan Event' sounds like a cracking name for a sci-fi novel!
Let’s get John Godier on it!
Black Swan sounds like a great name for a band. Or maybe there's a foreign language term that sounds cooler.
“The Black Swan Incident”.
Lagoon of the Black Swans
The black swan is already a book written by Nassim Nicholas Taleb. It is not a sci-fi book but it is full of statistical fat tailed events.
I feel that a great thought experiment in this context is how would you transmit such a signal? May give some clues on intervals to expect. However, just gathering as much data as possible is a better method to be fair. Have to have some sort of balance between clever methodology and brute force methodology.
Trying to guess how or why an alien civilization would do something is rather pointless. We've only truly been technological for about 100 years ourselves, we truly have no clue what an advanced technological civilization would be like. I expect 99% of what most people talk about (O'Neill cylinders, traveling through space as biological beings, etc) are probably very wrong and unlikely. Besides the how is much less important than why a civilization would send out signals. And we really have no basis for even guessing at alien psychology. So best to just do much, much better at listening and see what we can here.
I literally just thought "Hey, let's see what Cool Worlds is up to" - "uploaded 1 minute ago"

It was awesome that Peter Higgs was in the room and got the recognition he deserved.
1974, the Arecibo telescope send the most powerful broadcast ever deliberately sent into space.
We are now visible in the distance of 47 light years ^^
It is very much worth noting that we only ever sent that ONCE. It did not repeat.
Can the frequency of expected signals detected happen without considering the only example we have of high-powered transmissions from an intelligent civilization, namely, us? If that transmission took the form of something like the Arecibo message, how does that affect the probabilities?
The shout out to event horizon! Love it! :)
How would you know anything about t1?? Surely not starting bulding the equipment that could have detected another WOW signal earlier?
Doc, I could listen to you orate the Oxford Concise Dictionary. Thanks for the brilliant content.
I love your videos. Some of the best and most interesting on youtube that really do give realistic food for thought. Great work.
IDK how, but you make math way less confusing. That's wild. I have dyscalculia and math is my enemy
Thanks! That means a lot as I think hard about how to present the math in a digestible way
I have dyscalculia too and I can say that it wasn’t until 15 years ago that somebody laid things out in this manner that things changed.

Totally agree! The math in all Cool Worlds releases would paralyze me if not for David Kipping’s skill in unfurling it for an applicable situation.

@@ravenmad9225 Either is correct, and I don’t like pluralizing abbreviations.
At 10:20 it's shown that the WOW Signal was at 1420.4 khz. That would be in the Amateur Radio 20 meter band. Was ET using CW, AM, SSB?
Was a slight error there, should have been MHz!
Out of curiosity, is your keffyiah a statement of support for Palestine?
"For in that approach lies the possibility that we will find malicious aliens who will farm us for meat."
And I'm here for it.
We only sent one arecibo message, but expect more from aliens. Oh the irony!
I've replied to this comment a few places elsewhere but the point is that such a signal is inherently incredibly unlikely to be detected, since it demands an short-duration signal (~ of order minutes) to be sent out way once in *all time* that we just happened to be looking towards at the right place and at the right time (the odds are genuinely astronomical)

I understand Dr. Kipping, I was just pointing out the irony and humor of it ;) a comedy of errors

Its definitely possible. physicist michio Kaku was just suggesting that. If ETs exist, they likely travel in digital form by lasers, and occupy 3D-Printed bodies, and blend in with the people on the planet they are visiting
