We may not be truly “alone”. But I suspect that intelligence life is so widely separated in time and space, and so short lived, that we may as well be.
That's been my guess too. There may have been plenty of intelligent life out there in the past, but their time has come & gone. Granted, if any is out there now, even huge distance can be covered with a powerful enough transmitter, even if it takes years
@@corey2232 I wonder about a horizon effect. If intelligence is rare enough to develop and late enough to emerge, its detection would be not just practically but actually impossible this early in the universe's history (though not forever). IOW we could be just a few hundred million years too early for any evidence being produced 'right now' to reach us.
@corey2232 can't remember the video I watched, but according to said unknown individual (may have been Isaac Arthur) we may actually be the first intelligent life in the universe - because of the steps required to get to intelligent life. I tend to think that is a likely answer. Not that we are the absolute first, but in that first grouping of life.
Also keep in mind we've only started recently looking for life within a very limited scope of the universe. It's like scooping a tablespoon of water out of the pacific ocean and concluding that there's no fish in it because you haven't found any yet.
I hear than analogy frequently, but I think it's a poor comparison. We've barely done that. All we can do is optically look for signs of aliens and scan for radio frequencies, all within the observable universe. And the overwhelming thing is the observable universe is but a small fraction of what we assume to be the entire universe
7:43 Former signals analyst here. The difficulty with frequency hop signals is not so much detecting them- they have a distinctive appearance on a spectrograph- as it is deciphering them. Since the signal hops to a different frequency so quickly, it's hard to tell the exact hop order. And when there's dozens or even a hundred or more separate frequencies being used, it becomes harder and harder to decipher. If the signal was so weak that it was difficult to detect, then that would likely be the case for the intended recipient too, unless they were closer to the sender. This is true regardless of the type of signal used.
"gravitational wave communication" of a sort was postulated by Ursula K. LeGuin in her "Hainish" novels. It was called an "Ansible". I am sure that you were already aware of this. 😊
DSP guy here. i am SO glad you mentioned spread spectrum communications. all the wacky digital modulations making full use of the spectrum can amount to high entropy noise! you're the man john. i appreciate all your work. thank for your doing what you do.
I really want your take on the current possible reality, that aliens beings are already here on Earth (flying in our atmosphere, solar system, oceans), have been quietly observing, interacting with us in highly controlled scenarios, etc, and have potentially been here maintaining a secret presence for a very long time. I'd love that video. It seems to be the only one most people aren't willing to explore the possibilities of, and it's becoming the most likely scenario in recent years
@@KnightspaceORG nasa literally just said that one of the biggest hurdles they have to get over is the ridicule for investigating uap’s…yes its being explored but not nearly as it should due to the stigmatism
@@Bella-vt7olIf the human race is holding itself back because it don’t want to be picked fun of then we don’t deserve to advance and we should do this beautiful planet alone and take care of it and destroy ourselves and not her
We know so little about what goes on around stars. It’s entirely possible somewhere out there an alien civilization received our first radio transmissions a few decades ago and have been actively listening and studying us ever since. All while taking steps to not broadcast themselves for us to learn of them. Maybe they broadcast for a period then learned of us and made the decision to go dark. Maybe on earth we pick them up, learn about them, and then see their discussions about detecting our radio waves, their reactions, and decision to go dark. We get cut off bc they don’t broadcast any more…Sorry got carried away but this scenario is really interesting… what would we do then? Having just seen these aliens with space tech and nukes decide to go dark. What if we had only just discovered them and only had a year or two of time we could tune in?
The infinitesimal amount of time in which we have begun delving into the electromagnetic spectrum for fun and for profit, versus the age of the universe, the lightspeed delay obscuring "current events" even as close as 4.2 light years away (let alone those at the extreme edge of our observations), the objects/structures obscuring observations past themselves (I don't know of any telescopes which have seen through the hub of our own galaxy to the other side with any clarity, for example), and our lack of comprehensive coverage of the "sky" surrounding our solar system, means that I won't be surprised to learn they are very nearby; nor surprised if we receive communications from a billion years ago or more, once we learn how to tune in just right.
I don't know what our best chances are of alien communications, but I believe our best chance to find alien life is within the solar system, just because we can reach it and there are some good candidate environments on several moons and maybe even Mars.
11:44pm and I can't sleep (work in morning) and I was just listening to the most recent JMG video, to see ANOTHER video is posted 3mins ago!!! YAY! 😂😂😂👏
I feel like people often forget just how vast the universe is and how incredibly slow the speed of light really is. It's not like the sci-fi movies and books...there is effectively no practical way to communicate in real-time with any civilization, including our own, should we ever venture far enough.
Light speed isn't slow, space is just that big. And if the speed of light is the speed of causality, it stands to reason that the maintenence of a galactic or inter-galactic empire is highly impractical if not impossible.
That's such a close-minded point of view. If a civilization is thousands of years ahead, they could have science or technology unfathomable. Remember, people said the same thing about the moon.
It's like walking through a dark forest at night, yelling "Hello!", and then 5 seconds later hearing someone/something yelling something unintelligible back. What would you do? Probably stay quiet.
But isn't the problem with "we don't see any in other galaxies" the fact that those galaxies are so far away that the light we're seeing is from millions of years ago? For all we know entire galaxies have been swallowed up by alien empires today but we won't know that for another few million years.
What if asking "Where are the aliens?" is somehow the wrong question in itself, because there's some fundamental concept about this universe we are simply unaware of?
yeah. What then? I mean, your question could make sense, if we KNEW that "there's some fundamental concept about this universe we are simply unaware of." But we don't know whether "there's some fundamental concept about this universe we are simply unaware of."
@István Sipos you really don't think there are some fundamental concepts of the universe we're not aware of? Explain dark matter, explain FRBs, explain Gravitational singularities, explain string theory. Since you know all the answers please let me know I'm super interested in knowing all the fundamental concepts of the universe. Thanks.
I'm a big fan of the "subspace comm" idea. It feels perfectly plausible to me that we might not know everything a million year old civilization would figure out about how to communicate. But that doesn't explain why *nobody* seems to have built Dyson spheres or the like. Some of the effects of a large old technological civilization would be visible to us regardless of the specific technologies they are using. I think that implies there aren't many million year old technological civilizations. Whether they kill themselves, or "ascend" to some cool kids club, or stick themselves in a computer or a pocket universe, but they wind up either no longer a civilization or no longer in our galaxy long before they would grow to be the sort of large empire we would expect to be able to detect somehow.
When we set off our first Atomic bomb, we sent a pretty significant "signal" unintentionally in EVERY direction. If there's been a dormant probe along our asteroid belts or planetary rings near by, they coulda woken up to signal who left it. Then depending on the distance they've travelled SINCE leaving it, would be how long it'd take for them to return. Maybe probing is all the "traveling" machines do, until the signal is received at home world, and "prospectors" sent our way to "see" what our progress will become. I love your channel brother, great and inspiring stuff. Thought experiments are ALWAYS guaranteed watching your vids.🤘👍🤘😁
You know what video nobody wants to watch? A sad story of a planet surrounded by endless space and unreachable worlds. It seems to have gained more traction, popular cosmologists suggesting one active intelligent civilization per galaxy per era might be as probable as we could hope. Reconciling why we haven’t seen or heard anything is difficult at many levels. Great and thoughtful video again!
Another great show John , No wonder we can't decode the wow signal I can't get my satellite box to behave itself, it changes where the channels are at random!! . PEACE and LOVE to EVERYONE.
If it turns out some UAPs are actually extraterrestrials despite doubts, I halfway expect mainstream scientists to _INSIST_ the aliens communicate in a way which makes use of their radio dishes, and refuse to talk to them in person.
We put a lot of weight on the idea that nothing we see can be that unusual. Yet, when Oumuamua was the first interstellar object spotted and it also had one of the highest albedo differences of any object ever seen, it didn't seem to register on people. Then there was the mysterious acceleration without the off gassing that usually accompanies a comet's acceleration out of the system. Then there was the very difficult to explain position that it was hanging out in interstellar space. But, "It is a comet. Nothing to see here." We use the rule that nothing is statistically overrepresented to knock down hypotheses, but when faced with a statistical anomaly, we ignore it.
Great video as always, always a good day when you post a video. I am increasingly leaning towards inter-dimensional/parallel universes for answers to the Fermi Paradox, if you just look at the "physical" universe I think there should have been some indication of life elsewhere by now, but if there are 11 dimensions as String Theory suggests, some existing virtually on the same "membrane" as us maybe they can somehow cross over? Might explain a whole load of paranormal stuff?
It makes me think... On the vast history of Earth, how many times, if ever, may this planet has been visited and photographed by B. Starshot like tiny probes.
One day we'll discover some brand new physics that unlocks a brand new way of communication. We'll build the very first receiver and the second we turn it on we'll hear multiple alien species reading a news broadcast and space weather reports.
When you spoke of Rose Bush thorns and so on, for some odd reason while this movie isn't exactly related in the sense of Aliens, communication, and so on. Just reminded me of it. But is called A Sound of Thunder. Time Travel back into time when dinosaurs existed, a mistake, then totally changed the time from the previous travel in the beginning. Was thought provoking for me.
This planet would be interesting to an advanced alien civilization with us or without us. Planets capable of supporting life for billions of years are rare. We also look for them. If the distance wasn't prohibitive, those aliens would come to check this place out, perhaps rendering themselves undetectable.
No, the argument against radio-wave is valid for the simple fact that these civilization already move on to newer physics as you said. If they can travel trough wormholes or warp-speed, they should be able to communication via larger distances using the same principles. They could even be using the entanglement particles for all we know, and that is a know physics. In fact I think there's even studies about the practical applications in communication already. We don't know if their own path of knowledge had gave them better and easier ways to communicate. There's even the consciousness theory, where they are communicating via a conscious field that allow them to communication where distance becomes irrelevant.
Thank you for that awesome exploration. In the case of the aliens being in orbit down to the troposphere, light communication would seem to be most readily receivable by the most humans, as demonstrated in the movie CE3K. If these aliens have been here for awhile and listened in on our communications, they should be smart enough to have deciphered our languages, and things like Morse code and ASCII (text data) transmissions. Both Morse code and ASCII lend themselves to light communications very readily. A little bit of tech would be needed to pick up and process the light pulses coming from the aliens to record and decipher the incoming message into text and speech., and to produce the outgoing beam . Sounds like that would be a fun project.
Making a Von Neuman Probe sounds like a very difficult task. The largest (or one could say the smallest) problem is making it able to create a chip fabrication plant. I presume this probe would need at least 1 CPU. Once the fabricator has been created, it wouldn't be all that much more difficult to build 100 chips than 1 (or chips for 100 probes rather than 1 probe).
Let's say we can make universes and know everything that will ever happen there. Making random universes, you would probably run into ones with no life, and ones with ever-present life, but how many would only have 1 intelligent species, or they're just so distant that they never notice each other, or even ones that question what we mean by life and intelligence. I don't really think we can call it likely or unlikely we are alone in the universe, because we don't know much about how universes work since we only have access to one, and our access is severely limited
Will you explain to the aliens about the Dinosaurs? Aliens know all about that, very dismayed. Scared them away for the most part so I extend gratitude.
0:10 Still the best coordinates of space to take a picture of with any future technology. On this particular picture you can even see the two galaxies overlapping forming a 90° bend (bottom left), several gravity lenses, but most stunning of all: you can see some gaps in the spectral lines from some of the interference patterns on stars. I would not be surprised if we discover later there was an actual super nova hidden in this picture somewhere.
You hit on my belief here. Its not that the universe is devoid of life except for us, but it is simply too spread out for us to find other intelligent life.
Fire never goes obsolete, but we do use microwaves to cook, not fire. And describing a microwave to an ancient person, they would think it is overkill from just using fire. So, I think it is a matter of perspective.
Fermi Paradox solution: maybe we're in a designated radio quiet zone. The Earth's biosignatures having been observable for billions of years, perhaps advanced aliens in the Milky Way wanted to see if Earth would evolve intelligent life, and so designated it as a radio quiet zone, prohibiting anyone from transmitting radio signals towards the Earth, so that any signals that did come from Earth could be picked out of the background. I mean, there are techniques for multiplexing signals together, but not knowing ahead of time what kind of signals intelligent Earth life would employ, they decided to just prohibit transmissions in our direction altogether.
I was just watch8ng a video on neutrino based communication and picture this. The first neutrino "radio" comes online and all the sudden the great silence is replaced with the great cacophony. Just imagine turning that thing on, getting conformation of alien life and the realization that we're basically surrounded. I can see a technician reaching for the off switch going "nope, nyet, nein, hell no, f@#k no"
If we were that surrounded though? And if it was as simple as finding the "tachyon" oscillation of neutrinos? I think the bigger problem might be trying to figure out what the signal (present day activity) is in all the noise ("information" echoes from iterations of the past and future that may or may not have happened). There might only be a dozen-ish exo-species using that kind of tech to talk, but in the process they could end up sounding like _billions_ of people without the right methods of parsing and filtration.
Honestly, if I were an alien living on Proxima B / in the Alpha Centauri system... I'd be shit-scared right now. Light sails come first, then robotic probes. Then the Imperium of Man shows up...
The fact that a single point of contact with an advanced alien space faring civilization could have them at our doorstep in just a couple minutes is ... quite terrifying.

Hello Mr. Godier! Would you be interested in doing a speculative video on the possibilities of alien life that is not "bound" to matter, sentient with energetic form?
One seriously has to deduce the fact that Scientists or Researchers have already detected multiple super habitable planets or planets that are more habitable than Earth. They seriously put real research into those worlds
4:54 I believe this is a misperception. An interferometer "the size of a star system" might be quite insensitive. It will have a phenomenal resolution, yes, but telescope sensitivity is a function of collection area, not mere diameter.
10:44 There are plenty of encryption algorithms that are immune to quantum computers, and the quantum computers we are currently building are useless for breaking encryption. You are in the vicinity of a good point though - and it ties into the earlier point about spread spectrum broadcasting. The more advanced our signals get, the harder they are to distinguish from noise. Compression and encryption both make transmissions look more like noise, and the transmit power keeps going down as receivers get better and the need to pack more transmissions into limited space (both physically and in terms of frequency availability) keeps increasing. The only signals that we are likely to have a chance to pick up are radar, which is intrinsically high power. Communication signals will be compressed, likely encrypted, and on a narrow beam likely not aimed at us, unless we are the target.
I think there is a recking between General/Special Relativity/Standard Model and a 'detached' (from human preconceptions) assessment of, and explanation of different aspects of the universe. - Neg mass particles, non-linear chronitons, variants of M theory (most destroy the above models),

Great video as always, always a good day when you post a video. I am increasingly leaning towards inter-dimensional/parallel universes for answers to the Fermi Paradox, if you just look at the "physical" universe I think there should have been some indication of life elsewhere by now, but if there are 11 dimensions as String Theory suggests, some existing virtually on the same "membrane" as us maybe they can somehow cross over? Might explain a whole load of paranormal stuff?
Well said John..
always excellent.
If this ain't the best channel on youtube, I dunno which is.
It makes me think... On the vast history of Earth, how many times, if ever, may this planet has been visited and photographed by B. Starshot like tiny probes.
What if they received all messages,but doesn't want to respond?
One day we'll discover some brand new physics that unlocks a brand new way of communication. We'll build the very first receiver and the second we turn it on we'll hear multiple alien species reading a news broadcast and space weather reports.
Or maybe an alien Hitler announcing the commencement of alien Olympic games.
I think anything subluminal will not be able to fill that role.
When you spoke of Rose Bush thorns and so on, for some odd reason while this movie isn't exactly related in the sense of Aliens, communication, and so on. Just reminded me of it. But is called A Sound of Thunder. Time Travel back into time when dinosaurs existed, a mistake, then totally changed the time from the previous travel in the beginning. Was thought provoking for me.
This planet would be interesting to an advanced alien civilization with us or without us. Planets capable of supporting life for billions of years are rare. We also look for them. If the distance wasn't prohibitive, those aliens would come to check this place out, perhaps rendering themselves undetectable.
I met Seth Shostak a couple of days ago. He actually said he expects we will receive an alien radio signal within the next 10-15 years.
No, the argument against radio-wave is valid for the simple fact that these civilization already move on to newer physics as you said. If they can travel trough wormholes or warp-speed, they should be able to communication via larger distances using the same principles.
They could even be using the entanglement particles for all we know, and that is a know physics. In fact I think there's even studies about the practical applications in communication already.
We don't know if their own path of knowledge had gave them better and easier ways to communicate.
There's even the consciousness theory, where they are communicating via a conscious field that allow them to communication where distance becomes irrelevant.
Thank you for that awesome exploration. In the case of the aliens being in orbit down to the troposphere, light communication would seem to be most readily receivable by the most humans, as demonstrated in the movie CE3K. If these aliens have been here for awhile and listened in on our communications, they should be smart enough to have deciphered our languages, and things like Morse code and ASCII (text data) transmissions. Both Morse code and ASCII lend themselves to light communications very readily. A little bit of tech would be needed to pick up and process the light pulses coming from the aliens to record and decipher the incoming message into text and speech., and to produce the outgoing beam . Sounds like that would be a fun project.
That's probably how the U.S. government has been communicating to the aliens this whole time.

Making a Von Neuman Probe sounds like a very difficult task. The largest (or one could say the smallest) problem is making it able to create a chip fabrication plant. I presume this probe would need at least 1 CPU. Once the fabricator has been created, it wouldn't be all that much more difficult to build 100 chips than 1 (or chips for 100 probes rather than 1 probe).
Love this channel..Thank-you..so much...x
Let's say we can make universes and know everything that will ever happen there. Making random universes, you would probably run into ones with no life, and ones with ever-present life, but how many would only have 1 intelligent species, or they're just so distant that they never notice each other, or even ones that question what we mean by life and intelligence. I don't really think we can call it likely or unlikely we are alone in the universe, because we don't know much about how universes work since we only have access to one, and our access is severely limited
Will you explain to the aliens about the Dinosaurs?
Aliens know all about that, very dismayed.
Scared them away for the most part so I extend gratitude.
0:10 Still the best coordinates of space to take a picture of with any future technology.
On this particular picture you can even see the two galaxies overlapping forming a 90° bend (bottom left), several gravity lenses, but most stunning of all: you can see some gaps in the spectral lines from some of the interference patterns on stars. I would not be surprised if we discover later there was an actual super nova hidden in this picture somewhere.
You hit on my belief here. Its not that the universe is devoid of life except for us, but it is simply too spread out for us to find other intelligent life.
2:01 something about that scene makes me nostalgic
Fire never goes obsolete, but we do use microwaves to cook, not fire. And describing a microwave to an ancient person, they would think it is overkill from just using fire. So, I think it is a matter of perspective.
We still use fire to cook, be it in stoves or in barbecues.
Fermi Paradox solution: maybe we're in a designated radio quiet zone. The Earth's biosignatures having been observable for billions of years, perhaps advanced aliens in the Milky Way wanted to see if Earth would evolve intelligent life, and so designated it as a radio quiet zone, prohibiting anyone from transmitting radio signals towards the Earth, so that any signals that did come from Earth could be picked out of the background.
I mean, there are techniques for multiplexing signals together, but not knowing ahead of time what kind of signals intelligent Earth life would employ, they decided to just prohibit transmissions in our direction altogether.
I was just watch8ng a video on neutrino based communication and picture this.
The first neutrino "radio" comes online and all the sudden the great silence is replaced with the great cacophony. Just imagine turning that thing on, getting conformation of alien life and the realization that we're basically surrounded. I can see a technician reaching for the off switch going "nope, nyet, nein, hell no, f@#k no"
If we were that surrounded though? And if it was as simple as finding the "tachyon" oscillation of neutrinos? I think the bigger problem might be trying to figure out what the signal (present day activity) is in all the noise ("information" echoes from iterations of the past and future that may or may not have happened). There might only be a dozen-ish exo-species using that kind of tech to talk, but in the process they could end up sounding like _billions_ of people without the right methods of parsing and filtration.
Honestly, if I were an alien living on Proxima B / in the Alpha Centauri system... I'd be shit-scared right now. Light sails come first, then robotic probes. Then the Imperium of Man shows up...
The fact that a single point of contact with an advanced alien space faring civilization could have them at our doorstep in just a couple minutes is ... quite terrifying.

Hello Mr. Godier!
Would you be interested in doing a speculative video on the possibilities of alien life that is not "bound" to matter, sentient with energetic form?
One seriously has to deduce the fact that Scientists or Researchers have already detected multiple super habitable planets or planets that are more habitable than Earth. They seriously put real research into those worlds
I will give you credit John, your apparent faith in Aliens is as deep as any religious person's faith in God.
I don't see why we cannot have both. ;)
4:54 I believe this is a misperception. An interferometer "the size of a star system" might be quite insensitive. It will have a phenomenal resolution, yes, but telescope sensitivity is a function of collection area, not mere diameter.
10:44 There are plenty of encryption algorithms that are immune to quantum computers, and the quantum computers we are currently building are useless for breaking encryption.
You are in the vicinity of a good point though - and it ties into the earlier point about spread spectrum broadcasting. The more advanced our signals get, the harder they are to distinguish from noise. Compression and encryption both make transmissions look more like noise, and the transmit power keeps going down as receivers get better and the need to pack more transmissions into limited space (both physically and in terms of frequency availability) keeps increasing.
The only signals that we are likely to have a chance to pick up are radar, which is intrinsically high power. Communication signals will be compressed, likely encrypted, and on a narrow beam likely not aimed at us, unless we are the target.
I think there is a recking between General/Special Relativity/Standard Model and a 'detached' (from human preconceptions) assessment of, and explanation of different aspects of the universe.
- Neg mass particles, non-linear chronitons, variants of M theory (most destroy the above models),
I agree with Michio Kaku, alien communication will occur soon.
We made contact a long time ago. Wake up. You’re being lied to.
