If a type 3 civilisation exists it can be inferred our planet and species have already been surveyed simply because they have the technology to do so. They know we are here and they are not interested in contacting us. Even if we manage to detect them they will simply not care. They know what we are simply because they have the technology to know. If you were a leader of a type 3 civilisation, would you donate technology to a species that point nuclear weapons at each other? There will be no short circuiting history.

I think you are ignoring the fact humans are predators. That's given us a serious advantage in that predators are generally smarter. But the downside of being a predator is that you are totally dependent on resources provided on the food chain below you. If anything happens to upset the delicate order of that chain, then everything above that link goes extinct. Now fair enough, if you think all links in the chain below humanity are perfectly okay, then you have nothing to worry about.
Seti is based on a flawed premise, which is that extraterrestrials are using radio-frequency to communicate. Seems to me that advanced extraterrestrial beings would have evolved to a level where they can communicate across Interstellar space which would disallow RF transmission because of the slowness of the speed of light. What is more logical to me that these Advanced beings would have evolved to a level whereby they communicate via telepathy which the large SETI antenna arrays they're using cannot detect. Even if aliens were using RF to communicate there's the issue of synchronicity.
@Baltimorean Adventures raw unedited content and that is assuming the life on that planet is synchronous with ours. If their Planet came and went 12 billion years ago the signals might have passed through us already long before we're able to detect them. Synchronicity greatly reduces the odds
Good points. If you have an open mind, read these books by Marshall Summers : Allies of humanity (4 books) Life In The Universe. These books will confirm your thoughts but also answer why ET is not openly here.
Hopefully death holds the answer. Probably not, but wouldn't it be nice to die, and immediately open your eyes in a new world, and hear someone yell "next!!" As if the life you just lived was actually just a complex simulation you paid to experience.
The give away for our planet being here and having life on it, would be detected by aliens in the same way we are going about looking for alien worlds that support life. The give away would be the spectral analysis of the earths atmosphere where large amounts of oxygen would immediately indicate life. And there's almost no chance that our planet hasn't been surveyed.
His point is that any ET that we would get a signal from would have to be as advanced or more advanced than we are for us because if they weren't they wouldn't have built technology to communicate via radio waves. He's not saying that less advanced ET don't exist, only that we wouldn't know they were there, at least with this type of exploration.

Exactly, some people don't understand how silly we are scanning for radio waves, we might as well be scanning the skies for alien carrier pigeons with binoculars, if it is a radio wave it will be from a long ago (billions of years dead civilization) if the signal would even reach us after that distance, supposed smart people don't even realize how stupid they are even looking in this manner, at least you understand callum, one in ten thousand might even begin to grasp how complex this issue is. I don't scan for wifi networks by looking for smoke signals, and that's not even a close comparison of how lame our attempt really is using radio waves (light).
@@laceygreentrees1299 intelligence can be learned how much is different from person to person some just absorb more than others it doesn't mean that one unable to reach a high IQ is less than one with a high IQ it means to achieve are highest potential we all have to work together
"I don't know what's scarier, the thought that there's no other intelligent life in the universe, or that there is other intelligent life out there." I can't remember if it was Clarke or Asimov that said that.
They don't have to be more advanced. In fact most alien life is microbial. However, if we detect an alien broadcast signal, the statistical probability(given the age of the Milky Way galaxy) would be that they are a much older civilization provided that they have been broadcasting throughout their existence. However, this is a questionable premise given our planet will go radio broadcast quiet in the next 100 years. This would suggest that the radio broadcasting alien civilization (cont'd)
He is not extrapolating the exponential trend terribly far into the future so it is probably reliable. As for the distances and times involved, who cares? Hearing anything of intelligent origin would still be incredibly profound.
The answer to the Fermi Paradox.There is a beautiful loving Universe many people claim they experience when they are undergoing an NDE. Long before any Advanced Civilization gains the technology necessary for Interstellar Travel - they find a way to escape to that Universe. In other words, it is technologically easier to get to that other very pleasant and safer place, than it is to develop the Type II Civilization Technology necessary for Interstellar Travel. This explains why we have found no sign of an Advanced Alien Civilization anywhere in our Universe.
I'm glad you brought this up because that's another thing about the video I don't understand. Why would anyone think that radio waves are a technology that a) anyone thinks an alien civilization would be broadcasting into space and b) that anyone thinks aliens would be even able to detect the radio signals we have been putting into space. First of all, the period of time we will have been putting radio signals into space is almost over. And those signals themselves are very weak.
If you think about it logically, where they are from they probably thought at one point they were the only life in the universe. Just like we do. Imagine when/if we find any form of life elsewhere, dont you think we would be studying it? just as they would with us?
@@nahCmeR I believe intelligence Aliens exists 👽 but they would watch humanity because we are competition/ war like . Intelligence aliens 👽would not openly contacted humanity because it's dangerous . Humanity would have to traveller to different solar systems to contacted aliens 👽 I believe now . The answer has to be if intelligence Aliens exists they're hided/ watch humanity . The 2nd problem would be what doe's humanity have that intelligence Aliens would want and they can't get some where else or by watching humanity 🤔?
@@joyhouse4625 of course they are watching us, thats what they have been doing for hundreds thousands of years. They also interact with us, evidence by abductions and close encounters. They aren't afraid of us, we are literally ants to them, they have so much more power then we do they have nothing to worry about.
@@nahCmeR I don't believe intelligence Aliens are more powerful but they watching humanity/ Get information about earth. More information saying humanity/ earth 🌎 is being watched now. The information proves something is out there but scientists should re-think they're idea's. Intelligence aliens may see humanity has competition/ war like. This maybe good/ bad thing but this means humanity should move forward into solar system and universe. Humanity needs to pass forward because something going on/ something out there.
An intriguing issue is the capacity to travel such huge distances through space. Beyond our solar system the nearest star is about 280,000 equivalent distances from Earth to Sun, i.e., the nearest star is about 26 trillion miles from Earth. At the speed of light it takes just less than 10 minutes to reach the sun but 4.3 years to get to the nearest star. Obviously, if advanced life has been hovering in our neighborhood, then they figured out how to circumvent the speed of light barrier.
A commitment for something greater to understand and possibly achieve is always something to be admired. Hopeful to see results in near future. That is what i´ve got as a human being.
You may be thinking about radio waves such as those used by AM/FM radio stations but we broadcast a lot more than this. And it gets only bigger. Obvious examples are mobile phones, GPS but also all the electromagnetic radiations produced by all kinds of electronics. Maybe we can imagine an advanced civilisation which wouldn't produce any artificial radiations but the likelihood that we're not the only one to produce those is pretty high in my opinion.
I think that is an issue he effectively ferreted around. What about nuclear explosions? Those seem like they would be easy to detect somehow, but it also seems like any place we detect those would be on its last legs.
This was a beautiful talk, engaging, thoughtful and inspiring. Dr. Seth keep up the good work. I find it sad that so many people believe in ET without any scientific evidence but don't believe in global warming with all the evidence around us!
Radio signals can only travel at the speed of light so any signal we can receive could be thousands of years old if the signal survives. If faster than light communication is possible there would be a small period of time where a civilization uses radio and FTL communication, with FTL communication eventually replacing radio when the technology becomes cheap enough to implement everywhere. We most likely have a small window to catch radio signals.
Yes the real problem is synchronicity and it doesn't address the more significant issue that advanced alien beings probably are not using radio signals they're using telepathy which cannot be detected on the SETI arrays
in two dozen years seth will be in his 90s, so hopefully he does get to see or hear evidence of aliens, like all of them that dedicate there lives to the 'are we alone' question, hope its sooner rather than later.
Apart from all the technology and politics of SETI (which are all important in its own sense) the only lasting philosophical importance would be that ... dang! we are all alone after all in this vast real estate. Thanks to Science... Life is indeed a miracle, after all.
Everything we need is a common goal. It is not the intelligence of a species which differs from the others. One can very well kill one another by being intelligent. We only need to have an idea, a common dream. All we have to do is move forward collectively. For now, all we are doing is seeing in the short term, according to territories (countries) and their resources. We could have the universe, by our intelligence, but we prefer freedom, comfort ,security(in one way) and individual power.
(cont'd) would be at most 100 years more advanced then us. Now they couldn't be technologically equivalent to us in the 1600's simply because we hadn't invented radio transmission in the 1600's. Furthermore, since we have been radio broadcasting for about 100 years, the odds would be about even that they are more advanced then us. Finally, the odds for SETI's success are really remote given that they(radio capable civilizations) are on average much older and silent.
Well, do this as a hobby between your 20's to your 50's and see what's different at that time. But in the meantime, put your efforts into a better life for yourself and family and friends, right here, right, now.
We may be more unnoticed than you think. Most exoplanets discovered so far are more than 100 light-years away from us. It means the only signals they can currently see coming from Earth are from 1900 or before, certainly not a lot of interesting signals for them to study. So, if they're really more advanced than us, it's actually very likely that we find them before they find us.
Seth just going by the headline. I invite you to stay at my home and watch as supposed Stars move to questions you ask and that should help answer your questions
Stephen Hawking said if ET is out there, let him stay out there. Anyone reaching us by technology would not be intimidated by our pathetic defense measures. But that's the rub: we have no way of knowing if we are missing out on the wisdom and goodwill in the Universe, or avoiding annihilation. Sadly, the stakes are such that perhaps we should remain quiet, but only for now...
They are closer then you think!!! its all based of understanding of communication, vibrations, frequencies, energy, your thought process and your heart and it's harmonics
What is e.t. is using something more advanced then we are? Sub space or s faster than light communication things we can't even pick up? Besides we are trying to call France with a toy walkie talkie. I don't think we are going to reach them with are current methods.
I hear that Sleestak has grown up a bit since 2012, but it's still sad that such a prominent scientist who makes his living looking for ET, was in denial about the likelihood of ET. At 11:15 he makes a very apt analogy of pioneer ants exploring our kitchen counter, and thus being crucial to ant society. Then it takes him only about 70 seconds to completely forget and literally contradict that analogy by _mocking_ the idea of alien pioneer ants exploring our planet. I know that evidence is thin for the alien visitation idea, but it's not nonexistent. And seriously, you either believe in pioneer ants or you don't. If you expect to be taken seriously by thoughtful people, you can't literally praise an idea one minute and mock it the next. Which is a good example of why academia has been losing the alien visitation argument.
they show up on advanced radar systems. experienced pilots see them and report it frequently. the govt spends millions investigating them. thats good enough for me.
The problem in America is religion. There should be no religious activities whatsoever in ANY school. By all means teach the basic values of ALL religions but leave out the fundamentals. This leaves the mind open,otherwise religion closes the mind. Our children deserve the right to think unheeded. Would you agree ?
Great, Great Point !!! Organized religion or crime ? the universe is vast and endless - agreed ? religion implodes the day we have that 'close encounter' - maybe not in my lifetime BUT a lifetime - absolutely !
Video published in 2012, it is now 2021 and he is WELL on his way to losing that bet. He loses it if he dies first, but it could be truly lost for all time in 2 different ways, if there's no life within the milky way galaxy, or if the human race goes extinct, which is far more likely than he's giving it credit for.
It is obvious that terrestrial continents could not be formed by any known geological of chemical process. There are speculative articles in scientific journals, but non of these speculations enjoy much support. Hoffman's claim that it was a grazing collision between Earth and Theia does not make sense because the enormous heat of the collision would have melted the entire surface of the earth and liquid sial (granite) would have coated the entire surface of the earth (like Venus and Mars).
I have studied this subject for many years, I had no option really as a metallic disc came over head one evening in the 70's while I was outside my house with my friends, it was totally silent and looked like brushed aluminium and at about 1,000 feet. I have long yearned for the truth to come out over this whole thing. Does anyone see what I see in this broadcast?.....he is so precise about the time scale of 2 dozen years. WHY?.....looks like a classic case of priming to me. I believe SETI know full well about the E.T. visitations and have done for years, and that now we have so many credible people going public on you tube...Edgar Mitchell ...Gordon Cooper and ex-military bods...official disclosure is only a matter of time. Double chocolate on my cappuccino please Seth you old rascal.
Steve G, you need to get it drawn or have what you saw compared to other sighting which are similar to the craft you saw. That's what I would do if I was lucky enough to see it! You're damn lucky!
nice guy, interesting ideas - i believe that it would be selfish to support that we are alone in this galaxy... BUT on the other hand is crazy cause we are spending so much money on these equipment the same moments there are people starving. Thank you.
One trillion planets in our neighborhood alone and we still try to beat each other up over this tiny piece of crap we call earth. Can't we just go to space already?
Great speaker, funny, very interesting and comitted and pasionette about his chosen field. Of course we are not alone, the odds are against it completely
Saying we don't get along & we exploit everyone is rather simplistic. Do you expect Humanity to be perfect??? Also nations and alliances and even the Internet proves that we do get along. Any advanced civ would seek out and embrace new knowledge and diverse species they meet...since that's how we are moving forward right now. Evolution encourages increasing complexity. Intelligent life is inevitable given enough time and life is resilient, it has survived many catastrophes on the Earth.
In 2020 a spacecraft opened a porthole on a photo on the natal coast south Africa and left back to were it came from we still looking at the stars , they were on planet earth we did even know.
If you reject my argument about the continents, you still have to deal with the fact that no ET civilization has colonized the earth. All species living on earth are trying to colonize as many habitats as possible. If spiders could colonize outer space, they certainly would do it. If there are many intelligent species living on a planet, the most aggressive and ambitious of them will colonize outer space. It is not possible that all ET civilizations refrain from space colonization.
polka23dot well, if spiders colonised outer space it would be no threat to us. What makes you think all intelligent species would compete about the same habitats? An ant doesn't compete with a penguin, neither would they if they for some reason would be forced live in the same place
1. Is "nothing" possible? 2. How did the universe come about? 3. Is there a god? 4. What caused abiogenesis? 5. Does consciousness survive death? Please add YOUR questions 🙂
I hate when they take Moore's law for granted, and don't forget that any signal we might pick up, most probably traveled thousands of light years. ( Milky Way has radius about ~50k light years 'horizontally' and 500 'vertically', and while the center shadows a lot of the other part, we are still in an outer region. ) So those who sent it are either extinct or thousands of years more advanced than us. (Moore's law? :D) With that said, I am kinda hoping for a cup of coffee anyway. :)
I don't, back then i didn't know what i was talking about but now i have read several books on about the study of evolutionary biology and anthropology, its safe to say i am now a misanthrope. The guy i commented, i fully agree with now.
If ET civilizations had existed, they would have colonized the earth billions of years ago. The earth is unique because it has continents. Our continents are the most exotic geological features in the universe. Nobody knows how our continents formed, but it must have been extraordinarily rare event. Our continents made long evolution of life possible because they stabilized temperature of our planet. Extraterrestrial planets cannot support life for a long time because they have no continents.
How about millions or maybe just thousands? Do you know Cairo stands for Mars? Do you know there are pyramids on Mars? Maybe you are not so crazy. I would imagine that if Mars a million years ago, just to say a random example, had water, and an atmosphere similar to our own, and all of the sudden a nuclear war happens, or a meteorite crashes, then all the environment on Mars would be lost, so now they need to travel to the closest planet. Maybe even make it better. I don't know, make a moon or something, to regulate the climate. All that can happen and there is no way for us to dismiss that possibility. And that's just a single planet in our tiny solar system. There are at least a billion stars with planets and moons just in our galaxy. A galaxy that looks insignificant next to trillions of galaxies, many immensely bigger than our own.
I understand that, but the point i was trying to make is that most people don't think extra terrestrials can have worse technology than us, but about the same intelligence, which to me, is a "stereotype".
I for one applaud SETI for continuing their search even with all the skeptics ridiculing them. Just because we have been searching for 60 years means absolutely nothing! The problem is people are so wrapped up in themselves that they don't think of generations ahead of them. I, for one, think it's well worth the hard work even if it doesn't happen in my lifetime.

Exactly, some people don't understand how silly we are scanning for radio waves, we might as well be scanning the skies for alien carrier pigeons with binoculars, if it is a radio wave it will be from a long ago (billions of years dead civilization) if the signal would even reach us after that distance, supposed smart people don't even realize how stupid they are even looking in this manner, at least you understand callum, one in ten thousand might even begin to grasp how complex this issue is. I don't scan for wifi networks by looking for smoke signals, and that's not even a close comparison of how lame our attempt really is using radio waves (light).
Is SETI seriously still monitoring radio waves??? Tell me it ain't so. Please. How embarrassing.
This is what stand up is to a physicist.
They're so advanced we honestly couldn't comprehend the truth
Love the guy, smart, funny, informative.
He has NO idea about this topic. Clueless, IMO
well its been 7 years sense this talk...lol...thats 7 years of wasted money , and 7 more years of him getting a paycheck for nothing
Love the way he presents the material.
The subtitles are not mismatched, it's the light faster than the sound.
"Science is hard".
Yes. But stupid is easy.

geoff2204 being smart is hard...you have to be strong and smart to cohabitate with all these other sillies on the planet 🙄
That's why the Left is successful - stupidity is rampant.
@@laceygreentrees1299 intelligence can be learned how much is different from person to person some just absorb more than others it doesn't mean that one unable to reach a high IQ is less than one with a high IQ it means to achieve are highest potential we all have to work together
"I don't know what's scarier, the thought that there's no other intelligent life in the universe, or that there is other intelligent life out there." I can't remember if it was Clarke or Asimov that said that.
They don't have to be more advanced. In fact most alien life is microbial. However, if we detect an alien broadcast signal, the statistical probability(given the age of the Milky Way galaxy) would be that they are a much older civilization provided that they have been broadcasting throughout their existence. However, this is a questionable premise given our planet will go radio broadcast quiet in the next 100 years. This would suggest that the radio broadcasting alien civilization (cont'd)
He is not extrapolating the exponential trend terribly far into the future so it is probably reliable. As for the distances and times involved, who cares? Hearing anything of intelligent origin would still be incredibly profound.
Believing ET has already visited Earth is sad? Well I guess I'm part of the sad group..
Seriously. The ridiculous arrogance of his certainty in that statement is infuriating.
@@PatrickRob82 no its.. sad
@@ntme9 you're saf
The answer to the Fermi Paradox.There is a beautiful loving Universe many people claim they experience when they are undergoing an NDE. Long before any Advanced Civilization gains the technology necessary for Interstellar Travel - they find a way to escape to that Universe. In other words, it is technologically easier to get to that other very pleasant and safer place, than it is to develop the Type II Civilization Technology necessary for Interstellar Travel. This explains why we have found no sign of an Advanced Alien Civilization anywhere in our Universe.
Seth has a podcast called "Big Picture Science", if you're interested. It's freely available on iTunes.
I'm glad you brought this up because that's another thing about the video I don't understand. Why would anyone think that radio waves are a technology that a) anyone thinks an alien civilization would be broadcasting into space and b) that anyone thinks aliens would be even able to detect the radio signals we have been putting into space. First of all, the period of time we will have been putting radio signals into space is almost over. And those signals themselves are very weak.
Why are we so full of ourselves that we think ET would even have any interest in us much less contacting us?
If you think about it logically, where they are from they probably thought at one point they were the only life in the universe. Just like we do. Imagine when/if we find any form of life elsewhere, dont you think we would be studying it? just as they would with us?
@@nahCmeR I believe intelligence Aliens exists 👽 but they would watch humanity because we are competition/ war like . Intelligence aliens 👽would not openly contacted humanity because it's dangerous . Humanity would have to traveller to different solar systems to contacted aliens 👽 I believe now . The answer has to be if intelligence Aliens exists they're hided/ watch humanity . The 2nd problem would be what doe's humanity have that intelligence Aliens would want and they can't get some where else or by watching humanity 🤔?
@@joyhouse4625 of course they are watching us, thats what they have been doing for hundreds thousands of years. They also interact with us, evidence by abductions and close encounters. They aren't afraid of us, we are literally ants to them, they have so much more power then we do they have nothing to worry about.
@@nahCmeR I don't believe intelligence Aliens are more powerful but they watching humanity/ Get information about earth. More information saying humanity/ earth 🌎 is being watched now. The information proves something is out there but scientists should re-think they're idea's. Intelligence aliens may see humanity has competition/ war like. This maybe good/ bad thing but this means humanity should move forward into solar system and universe. Humanity needs to pass forward because something going on/ something out there.
An intriguing issue is the capacity to travel such huge distances through space. Beyond our solar system the nearest star is about 280,000 equivalent distances from Earth to Sun, i.e., the nearest star is about 26 trillion miles from Earth. At the speed of light it takes just less than 10 minutes to reach the sun but 4.3 years to get to the nearest star. Obviously, if advanced life has been hovering in our neighborhood, then they figured out how to circumvent the speed of light barrier.
A commitment for something greater to understand and possibly achieve is always something to be admired. Hopeful to see results in near future. That is what i´ve got as a human being.
You may be thinking about radio waves such as those used by AM/FM radio stations but we broadcast a lot more than this. And it gets only bigger. Obvious examples are mobile phones, GPS but also all the electromagnetic radiations produced by all kinds of electronics. Maybe we can imagine an advanced civilisation which wouldn't produce any artificial radiations but the likelihood that we're not the only one to produce those is pretty high in my opinion.
Problem with subtitles...
I think that is an issue he effectively ferreted around. What about nuclear explosions? Those seem like they would be easy to detect somehow, but it also seems like any place we detect those would be on its last legs.
kowalityjesus just like this one, maybe it won't survive more than 1000 years after its first nuclear explosion :-(
This was a beautiful talk, engaging, thoughtful and inspiring. Dr. Seth keep up the good work. I find it sad that so many people believe in ET without any scientific evidence but don't believe in global warming with all the evidence around us!
Oh Bobby *heavy sigh*
Radio signals can only travel at the speed of light so any signal we can receive could be thousands of years old if the signal survives. If faster than light communication is possible there would be a small period of time where a civilization uses radio and FTL communication, with FTL communication eventually replacing radio when the technology becomes cheap enough to implement everywhere. We most likely have a small window to catch radio signals.
Yes the real problem is synchronicity and it doesn't address the more significant issue that advanced alien beings probably are not using radio signals they're using telepathy which cannot be detected on the SETI arrays
ET is here and has been all along , just part of life every where.
in two dozen years seth will be in his 90s, so hopefully he does get to see or hear evidence of aliens, like all of them that dedicate there lives to the 'are we alone' question, hope its sooner rather than later.
MegaBspark if hes in his 90’s we can dress up and tell him we’re aliens
I wonder how good old Seth is taking the revelations coming out from ‘to the stars academy’....with a stiff drink I should imagine.....oh dear.
Apart from all the technology and politics of SETI (which are all important in its own sense) the only lasting philosophical importance would be that ... dang! we are all alone after all in this vast real estate. Thanks to Science... Life is indeed a miracle, after all.
It takes 4 million years for a radio wave to hit the end of our galaxy...
Everything we need is a common goal. It is not the intelligence of a species which differs from the others. One can very well kill one another by being intelligent.
We only need to have an idea, a common dream. All we have to do is move forward collectively. For now, all we are doing is seeing in the short term, according to territories (countries) and their resources.
We could have the universe, by our intelligence, but we prefer freedom, comfort ,security(in one way) and individual power.
(cont'd) would be at most 100 years more advanced then us.
Now they couldn't be technologically equivalent to us in the 1600's simply because we hadn't invented radio transmission in the 1600's. Furthermore, since we have been radio broadcasting for about 100 years, the odds would be about even that they are more advanced then us.
Finally, the odds for SETI's success are really remote given that they(radio capable civilizations) are on average much older and silent.

Well, do this as a hobby between your 20's to your 50's and see what's different at that time. But in the meantime, put your efforts into a better life for yourself and family and friends, right here, right, now.
We may be more unnoticed than you think. Most exoplanets discovered so far are more than 100 light-years away from us. It means the only signals they can currently see coming from Earth are from 1900 or before, certainly not a lot of interesting signals for them to study. So, if they're really more advanced than us, it's actually very likely that we find them before they find us.
Seth just going by the headline. I invite you to stay at my home and watch as supposed Stars move to questions you ask and that should help answer your questions
joseph uscila where do u live?
Good speaker, like the ant anecdote . The ant queue vs the few ones who are explorers but make or break the ant colony
Stephen Hawking said if ET is out there, let him stay out there. Anyone reaching us by technology would not be intimidated by our pathetic defense measures. But that's the rub: we have no way of knowing if we are missing out on the wisdom and goodwill in the Universe, or avoiding annihilation. Sadly, the stakes are such that perhaps we should remain quiet, but only for now...
HERE'S what this lecture doesn't point out: If intelligence life is out there, there's a 0% chance they don't already know we are here.
They are closer then you think!!! its all based of understanding of communication, vibrations, frequencies, energy, your thought process and your heart and it's harmonics
What is e.t. is using something more advanced then we are? Sub space or s faster than light communication things we can't even pick up? Besides we are trying to call France with a toy walkie talkie. I don't think we are going to reach them with are current methods.
What if we're so insignificant that we're the pioneer ant on the counter 😶
I hear that Sleestak has grown up a bit since 2012, but it's still sad that such a prominent scientist who makes his living looking for ET, was in denial about the likelihood of ET.
At 11:15 he makes a very apt analogy of pioneer ants exploring our kitchen counter, and thus being crucial to ant society. Then it takes him only about 70 seconds to completely forget and literally contradict that analogy by _mocking_ the idea of alien pioneer ants exploring our planet.
I know that evidence is thin for the alien visitation idea, but it's not nonexistent. And seriously, you either believe in pioneer ants or you don't. If you expect to be taken seriously by thoughtful people, you can't literally praise an idea one minute and mock it the next.
Which is a good example of why academia has been losing the alien visitation argument.
they show up on advanced radar systems. experienced pilots see them and report it frequently. the govt spends millions investigating them. thats good enough for me.
18:30 Dumbledore was there...he must be planning something big😳

Holy shit I can see him

Well would you look at that! ...indistinguishable from magic! Lol.
We can’t even treat each other humanely let alone ET
The problem in America is religion.
There should be no religious activities whatsoever in ANY school.
By all means teach the basic values of ALL religions but leave out the fundamentals.
This leaves the mind open,otherwise religion closes the mind.
Our children deserve the right to think unheeded.
Would you agree ?
Great, Great Point !!! Organized religion or crime ? the universe is vast and endless - agreed ?
religion implodes the day we have that 'close encounter' - maybe not in my lifetime BUT a lifetime - absolutely !
You are pointing the antennas the wrong way. They are underground and under the sea in the Mariana's Trench
Video published in 2012, it is now 2021 and he is WELL on his way to losing that bet. He loses it if he dies first, but it could be truly lost for all time in 2 different ways, if there's no life within the milky way galaxy, or if the human race goes extinct, which is far more likely than he's giving it credit for.
I just looked Seth Shostak up. He's 77 years old. Yep, I'd take that bet, if not for the fact that he won't be alive to pay out.
It is obvious that terrestrial continents could not be formed by any known geological of chemical process. There are speculative articles in scientific journals, but non of these speculations enjoy much support. Hoffman's claim that it was a grazing collision between Earth and Theia does not make sense because the enormous heat of the collision would have melted the entire surface of the earth and liquid sial (granite) would have coated the entire surface of the earth (like Venus and Mars).
ET is out there because he's definitely not here.
I have studied this subject for many years, I had no option really as a metallic disc came over head one evening in the 70's while I was outside my house with my friends, it was totally silent and looked like brushed aluminium and at about 1,000 feet. I have long yearned for the truth to come out over this whole thing. Does anyone see what I see in this broadcast?.....he is so precise about the time scale of 2 dozen years. WHY?.....looks like a classic case of priming to me. I believe SETI know full well about the E.T. visitations and have done for years, and that now we have so many credible people going public on you tube...Edgar Mitchell ...Gordon Cooper and ex-military bods...official disclosure is only a matter of time. Double chocolate on my cappuccino please Seth you old rascal.
Steve G, you need to get it drawn or have what you saw compared to other sighting which are similar to the craft you saw. That's what I would do if I was lucky enough to see it! You're damn lucky!
nice guy, interesting ideas - i believe that it would be selfish to support that we are alone in this galaxy... BUT on the other hand is crazy cause we are spending so much money on these equipment the same moments there are people starving. Thank you.
One trillion planets in our neighborhood alone and we still try to beat each other up over this tiny piece of crap we call earth. Can't we just go to space already?
18:27 this guy... I think he knows something we don't.
i think it has to be .. life as we know it .. because we know of no other type of life other the one we are experiencing at this very moment ..
subtitles are very very outside of time
Great talk!
Great speaker, funny, very interesting and comitted and pasionette about his chosen field. Of course we are not alone, the odds are against it completely
Saying we don't get along & we exploit everyone is rather simplistic.
Do you expect Humanity to be perfect??? Also nations and alliances and even the Internet proves that we do get along.
Any advanced civ would seek out and embrace new knowledge and diverse species they meet...since that's how we are moving forward right now.
Evolution encourages increasing complexity. Intelligent life is inevitable given enough time and life is resilient, it has survived many catastrophes on the Earth.
In 2020 a spacecraft opened a porthole on a photo on the natal coast south Africa and left back to were it came from we still looking at the stars , they were on planet earth we did even know.
Fantastic !...Loved it
Wellseth 2021. Yep real professor
If you reject my argument about the continents, you still have to deal with the fact that no ET civilization has colonized the earth. All species living on earth are trying to colonize as many habitats as possible. If spiders could colonize outer space, they certainly would do it. If there are many intelligent species living on a planet, the most aggressive and ambitious of them will colonize outer space. It is not possible that all ET civilizations refrain from space colonization.
polka23dot well, if spiders colonised outer space it would be no threat to us. What makes you think all intelligent species would compete about the same habitats? An ant doesn't compete with a penguin, neither would they if they for some reason would be forced live in the same place
that 1997 false alarm was on the exact day that I was born.
Chance of intelligent life on that day verses reality hehe
I feel for the deaf because these subtitles are way out of sync
Thumbs up for Dumbeldor in the audiance at the end :)
But, more importantly what if ET, from the movie "E.T. the Extra-Terrestrial", is out there?
The implication that we are miracles does not imply we are exclusive
1. Is "nothing" possible?
2. How did the universe come about?
3. Is there a god?
4. What caused abiogenesis?
5. Does consciousness survive death?
Please add YOUR questions 🙂
Great, very interesting video. Thanks.
I hate when they take Moore's law for granted, and don't forget that any signal we might pick up, most probably traveled thousands of light years. ( Milky Way has radius about ~50k light years 'horizontally' and 500 'vertically', and while the center shadows a lot of the other part, we are still in an outer region. ) So those who sent it are either extinct or thousands of years more advanced than us. (Moore's law? :D) With that said, I am kinda hoping for a cup of coffee anyway. :)
Almost one dozen years since he said this. We'll see if he turns out to be right.
Seth is Great!!
I don't, back then i didn't know what i was talking about but now i have read several books on about the study of evolutionary biology and anthropology, its safe to say i am now a misanthrope. The guy i commented, i fully agree with now.
If ET civilizations had existed, they would have colonized the earth billions of years ago. The earth is unique because it has continents. Our continents are the most exotic geological features in the universe. Nobody knows how our continents formed, but it must have been extraordinarily rare event. Our continents made long evolution of life possible because they stabilized temperature of our planet. Extraterrestrial planets cannot support life for a long time because they have no continents.
How about millions or maybe just thousands? Do you know Cairo stands for Mars? Do you know there are pyramids on Mars?
Maybe you are not so crazy. I would imagine that if Mars a million years ago, just to say a random example, had water, and an atmosphere similar to our own, and all of the sudden a nuclear war happens, or a meteorite crashes, then all the environment on Mars would be lost, so now they need to travel to the closest planet.
Maybe even make it better. I don't know, make a moon or something, to regulate the climate. All that can happen and there is no way for us to dismiss that possibility.
And that's just a single planet in our tiny solar system. There are at least a billion stars with planets and moons just in our galaxy. A galaxy that looks insignificant next to trillions of galaxies, many immensely bigger than our own.
I understand that, but the point i was trying to make is that most people don't think extra terrestrials can have worse technology than us, but about the same intelligence, which to me, is a "stereotype".
Really interesting guy. Can't wait for first contact !
