Just so you know John. Most of us wake up the next day and listen again so we can see what we missed after falling asleep. Surely I am not alone in this?
Lol, I actually hear it in my sleep. I have a headband with speakers inside, and I play a randomized playlist of both channels. I do listen to new event horizon videos on my drive into the office though. Some of the guests are just awesome!
You are not alone my friend. I just find it amazing that so many of us listen to John’s videos twice at the end and beginning of the day. One to relax to sleep and the other is listening with intent when we and our mind are awaken. It’s a most curious thing. But true it is, I’m relaxed listen to the video with interest the entire time I’m falling asleep when listening in bed.
I have always been pretty convinced that time is the solution to the Fermi paradox. Considering the vast VAST amounts of time we are talking about it seems incredibly unlikely that multiple intelligent species would be around at the same time. Like just stop and think about it. Let's say a species rose up right when earth was formed and they thrived for 500 million years (which is a really REALLY long time based on how we are going). That means they still would have be dead and gone for *4 billion years* before we came along.
There would be evidence of that civilization written both in the Earth's history and in the stars themselves. Because we see no evidence of alien civilizations, we can relatively safely assume that we are alone, at least in the galaxy.
I disagree strongly with this. I have the opinion that finding 'intelligent' life is not really a relevant question to begin with. All we need to do is find any type of life anywhere, at all. And I mean the most basic microbial or anything of the sorts. from that single point of discovery, we can basically just assume that there *is* intelligent life out there somewhere. finding any sort of life from a non earth substrate, would be proof enough for me that there is life that is lesser, and life that is greater, than humans. like I would have no doubts at all the second we find even the smallest undeniable proof of life. and I will stop calling people crazy who claim that see UFOs lol, (they are still crazy, or mistaken lol) but I would assume that it is possible that if there is life, there is more advanced life than us, and they may have technologies that we consider impossible today.
I think this is valid - that the size of time as well as the size of space make the likelihood of anyone finding anyone at the right time via comparable technologies a tiny needle in an astronomical haystack. Still, this isn't a question of one civilization detecting one other civilization, but rather this should be multiplied by some quantity of technological civilizations out there, at least the ones strewn across the area of space relevant to us. If the chances are one in a gazillion of finding intelligent life but there are a gazillion of them out there, wouldn't those odds balance out at some point...?
I find it hard to believe that there's no other intelligent life out there. The universe is simply too big for intelligent life to have only happened once. The issue is that same immense size though. We might simply be so far away from other intelligent life that we'll never be able to meet or even see them.
I’ve listened to all the fermi videos across channels, desperate to find my own educated conclusion. I really don’t think there is traditional aliens. If anything I think there is creatures living in oceans that may be intelligent like many of ours, just not in the same way as us and no real way to know they are there and not intelligent enough to look or know.
True. The problem is that this was for several centuries the basic argument for mermaids. Ocean is big, there's gotta be mermaids somewhere! The key issue is that we still don't really know what life is ir how it came to be here. Certainly every other place we've visited is 100% sterile as far as we can tell. We really need to find life somewhere else before we can make this claim. Also, the lazy claim that "nature abhors a one-off" simply is not true, regardless of how many times JMG repeats it. There are one-offs all over the place just on earth, at least in some sense. Only one Big Butte. Other places a bit similar to it, but it's recognizable and unique in many ways. One Barrier Reef. One Kilimajaro. One London. Etc. Basic physics repeat endlessly on a simple pattern, but not the expressions of those physics. The same "science" that led JMG to say this is also telling him that every snow flake is unique. It's almost a trope. But both things can't be true at once.
Or we may be trivially rejecting evidence which indicates another species has already figured out how to traverse the immense distances and has been visiting our world for some time (i.e. UAPs). Perhaps they are observing us just as we observe less sophisticated species here. We humans don't march into ape areas and announce "we are a superior species and we have come to be friends." Apes aren't really capable of understanding our motives anyway, just as we might not be capable of understanding the motives of some other intelligent life.
Humans are a anomaly in that we're the only thing ever that created technology and the ability to travel into outer space. The living organisms that are on other planets are animals that just act on instincts. Hum

I am on the short end of a) exploring space and b) discovering life elsewhere , that is, I am getting old and face the prospect of endless reiterations of these themes while we effectively stand still.
It seems like we'd hear from them via radio emissions by now. Unless you think humans are the only ones that can discover it or use it, it's the strongest argument against us not being alone.
Personally I find a combination of the rare earth, early in the game, rare complexity and intelligence, and the fact that we’ve only scratched the surface of searching to be a satisfactory answer to the Fermi paradox
It’s sad to think there are lifeforms who may have developed in a galaxy filled with life - so their civilization are able to confirm alien life - meanwhile us humans are so far away from others that we are essentially alone, left to ponder the question that can never be answered, simply because of a dice roll that had us created in a pocket of space with only us in it.
you complete my bed time ritual John, every time you upload I know I'll have no problem winding down for bed. Your podcast "Event Horizon" is for daytime listening, during commuting or down time. But it's this channel I find myself checking more nights than not, just in case I missed an upload lol
That could make a good sci-fi story. Humans build a ship that travels .999 light speed to search the galaxy for life. They find nothing the whole time and finally get to the other end of the galaxy where they discover an inhabited technological planet, only to discover it is inhabited by humans who discovered wormhole technology five thousand years after they launched.
It's remarkable, how quickly we can expect any species to evolve once it invents computers and aims for artificial intelligence. Evolution will effectively become a vertical line on a graph of the subject. All physical processes will be mastered in short order, and good luck figuring in what direction such a species might head.
I like to imagine what would have happened if the dinosaurs had never gone extinct? It's entirely possible that reptiles could be the dominating species on Earth. Environmental factors are everything and they are the deciding factor in which classes of organisms continued to evolve into the dominant lifeform. Who knows what has happened on distant worlds with different environments? I love this kind of thinking, I find it exciting and thought provoking. Thanks John 👍
I like to imagine what happened if some dinosaurs DNA got blown out into space when the asteroid hit. What if that DNA was able to grow in an environment?
Dinosaurs didn’t go extinct. We just call them birds which are very intelligent. Also dinos aren’t reptiles. However stu Art, your point is well taken. Those dinosaurs lived for over 100 million years. It’s just that the environment was not maybe “challenging “ enough to get them to the techno level. Or, maybe it was and as you know, 99% of fossil evidence is missing so we won’t know if they were that advanced
@@Boogaboioringale This depends on your definition of the word "reptile". There are at least three possible interpretations. One, the classical definition. Reptiles are only cold-blooded (again a somewhat contentious term) scaly tetrapods like lizards and snakes and turtles. Unfortunately, this means that "reptile" is a polyphyletic classification and therefore you can't really say what a reptile is or isn't since polyphyletic "groups" aren't really scientific. Two, the narrow classification. If you narrow the definition of reptile to be equivalent to Diapsid, then this would include lizards, snakes, turtles (which were once thought to be anapsid but we have since discovered their diapsid lineage), as well as crocodiles, birds, pterosaurs, and dinosaurs. This is the most common definition in scientific circles today, and that means dinosaurs are reptiles. Three, a wider definition. If you say that reptiles are equivalent to Amniotes, then not only are all the above Diapsids reptiles, but so are Synapsids which are mammals and our "reptile-like mammals" and "mammal-like reptile" ancestors.
The fact that dinosaur’s thrived makes me convinced that the aliens to be concerned about will be small in stature. Bigger creatures don’t need to be able to leave info to their offspring, the way intelligent humans can. I wonder if what small creature derivative could gives a run for our money, and I’d say a small bird is probably the base of the alien we should be worried about. … A bird-brain could be our eventual superior.
It's about intelligent life eg little green men. If they were as technologically advanced as ourselves or greater then we would've detected them in our solar system.
I liken it to this: you fall out of a plane and land in the ocean. You look around for 10 seconds and don't see any fish. “Must be no life in this here ocean!”
@@DistinctiveBlend tons of assumptions there too though. Not saying there are other civilizations in the solar system besides our own, just that we can’t definitively say that. There probably aren’t. But it is rather absurd to assume there is none anywhere. It’s equally absurd to assume we’d be able to detect them; the scale of the universe is too vast. And us detecting them also assumes our rate of technological advancements will continue at the rate they have for the past 200 years or so. Just assumption after assumption with the Fermi paradox. This is why I like videos such as this where they shit on it.
I've always found the term "Outsiders" to seem most appropriate for possible extra-dimensional or alternate timeline intelligences that could have made the crossing to our universe. 'Alien' merely connotates strangeness or a foreignness based upon an otherwise familiar, or at least basically recognizable substrate. 'Outsiders' confers a sense of deeper strangeness where little or nothing is familiar or recognizable. "From Outside" any known boundaries or understood constraints.
Thoughtful, but I don't agree. We use the word "alien" because the word "alien" is a synonym for "other" or "unknown". An "outsider" would be a being that doesn't fit with an established tradition or society, something like that. One word is much more inclusive of possible permutations than the other. "Outsider" implies that we know something about whatever or whoever aliens could or could not be.
We are probably late or early to the game of life in the cosmos, or there is some bio filter we havent seen yet..late would mean some Coalition of Species already banned and are anonomously kept hidden from us or they went to War and total annilatiom, or we are some sort of lab test for them, or they hyper evoled and trraveling other dimensions or we are in some sort of simulation or blackhole paradox ...or intel life is just super rare ,We need to travel to find out these things its nearly imposiible to fathom out the unknowns through mere theory and analytics from a very very far distance that has a blindsude view. cause of time .. lastly almost forgot we never encountered them yet modern man is only 300k years old we are less then infants as a race in comparison with anything else in the Universe ...
I have an astonishing love of anything Sci-Fi, Space and Astronomy related. Love learning listening to this channel and Event Horizon. Yet one other thing I’ve found in listening to John’s calm voice is when it’s sleepy bed 🛌 to relax my mind to sleep. Thus, I end up listening to the videos twice. As I replay the same video after I wake up as well. Event Horizon are my getting dressed in morning routine and commute time listening with interest. Some things are just interestingly funny in life for odd reasons.
Love these videos, John. I very much lean towards the “early in the game” school of thought. Also, would love to see a Patreon goal of turbocharging the le Baron. Or perhaps trading it in for a Chrysler T.C. By Maserati.
@@dredelcottcryptozooligist4101 “…And furtha-moah, if you can find a bettah cah, buy it!”. I could just picture John at the St Louis cars & coffee. “God damnit, it’s not a fücking le Baron, it’s a TC Maserati!”.
I think the most obvious answer is... Life is likely plentiful in our incomprehensibly large universe but the distances are so great between civilizations that communication is near impossible until some insane sci-fi types of technology are created.
Two biggest mysteries in life: is there life out there in outer space? And how can JM Godier maintain a constant flow of good videos on the subject like he is doing right now? No one knows the answer but I'm sticking around to find out.
With out evidence you cannot know .. :) I am definitely open to the idea that even in an infinite universe some things might only ever occur once ! :) Let's call it a nice and neat trillion trillion stars that we can see, that's a 1 with 24 zero's after it, and then realise there are easily more than 24 considerations with odds of ten to one or greater for intelligent life to arise on a given planet, which means realistically, that it is highly unlikely there is anyone else out there.... Which is a great shame because I really want to meet ET :)
@@freezatron Do you consider evidence from usa air force as not good enough,,, If so all eye witness in court cases in law cannot be used as enough evidence to put people in jail for life.
@@enternext2210 An Unidentified Flying Object that does not appear to move according to known aerodynamic principles is not the same thing as an intelligently controlled craft of extraterrestrial origin.
"to detect other alien life" right at the beginning... hmmm... "other"... Hmmmm... makes me wonder if JMG isn't holding something back. Better go listen to @eventhorizon to see if I missed the "other" alien life 😊😊😂
Holding back quite a bit at the moment Mark. We have a very good chance of answering the question this year far more so than any other year I've been doing this. Watch JWST closely.
@@JohnMichaelGodier i knew jest was going to be awesome 10-15 years ago when we all thought it would launch in like 2015 or earlier. Didn't think it would be this impressive as it has been. Exciting tikes we live in. Thanks for all the great videos my friend
there's a specific kind of voice and intonation that penetrates my dreams and gives me dreams about what I'm actually hearing. you have that type of voice and I'm so glad I found this channel.
The notion of time being the primary constraint preventing intelligent life from interacting is a kind of existential horror to me. Or at least an existential tragedy.
Once intelligence spreads beyond its original star system, killing it all off before the stars themselves begin going out seems less possible than collecting all the COVID on Earth and sending it back to Wuhan.
Maybe millions of alien civilizations are all communicating with another technology like gravity waves. Maybe when we figure out how to do it we will suddenly have access to a universe wide web of information.
The issue there is the development of the kind of tech. we’d have to assume all aliens across the galaxy use that same technology and jumped straight to it. If not then we’d see the development written in radio waves. Remember the further we look out the further back in time we see.
@@timrobinson513 IMO they would use all of the good technologies. Like we currently use fiber optic and radio waves and copper wire for internet. Cell phone towers and satellites and cables. Different languages are auto translated. Different codes and protocols are auto translated. Example: Electromagnetic waves could still be used locally within a solar system, gravity waves used for intermediate galaxy distances, wormhole waves used to transmit between galaxies across the universe, maybe even something else to communicate to other universes. coders and decoders and translators automatically transfer the data to the correct form.
@@timrobinson513 However, the farther from the source the weaker the signal and more likely to get lost in the background. Ever notice how satellite transmissions tend to get wonky when the sun passes directly (more or less) behind the satellite you are trying to receive from? Now try to find the alignment to that radio beam from thousands of lightyears away and filter out the noise. All we really know is that there are no active transmissions within a few hundred lightyears of here. Pittance compared to the galaxy as a whole let alone the universe.
As always a sterling video, John! Your channels (JMG and EH) are truly the brightest gems in an infinite ocean of so much entropy and junk! Question: would it be possible for you to produce a similar video the likes of which you focus on the methodological difficulty of detecting technosignatures? I know you've delved into this subject before but where I'm specifically going with my question is I sometimes think we're just barking up the wrong tree by focusing too much on astrobiology. You did an amazing interview back in October with Caleb Scharf on that subject, i.e., his biome-dataome research paradigm. It's utterly intriguing and I think you said it best in a video you posted on your channel commenting on this: It could very well be that our universe has the optimal conditions for machine civilizations-- call it the selfish machine theory? 😉 In short, once technologically intelligent civilizations pass through certain great filters, They pretty much transcended their contingent biological evolutionary pathways--And once that happens then habitability becomes a totally different issue which you've brought up before (i.e., intelligent nano dust at the event horizons of black holes and interstellar space and that sort of thing.) It almost reminds me of my previous physics dissertation advisor the great David Ritz Finkelstein, Who already published a series of papers in the late 1960s hypothesizing that the universe might be a giant cosmic quantum computer, part of the early generation of "information paradigm" of physicists like John Wheeler who tried to derive "it from bit."
I love these what if questions and very useful information as well as hypotheticals bouncing around in my head as I relax Into the Night. I've been into this sort of thing since the early 1990s. Documentaries in general were much better back then as well as in the 1980s and 70s and John reminds me of those better times.
One theory that I have for why we “haven’t found anything” is that life on other planets could be so fundamentally different that we might not classify it as life or it may fly under our radar
@@elizabethsnowpaws3751wait, there’s a cookie jar somewhere that has a lock on it? That’s not really a jar anymore if it’s locked and needs a key. Whatever drugs you’re on, stop taking them
Thank you for being a bright spot in a dark world. I love the content concerning the Fermi Paradox. Hoping to see more on the Dark Forest theory in the coming months. You're truly an amazing person with a gift for speaking. Thanks again
I think the problem with progress lies in the fact that people assume that things elsewhere function exactly like where you are now, that life forms elsewhere exactly like here, that other living beings might have similar physical features to yourself. Maybe there are different sets of rules that are opposite to how things function this side. Maybe everything we think we know about the outer side is not how it seems.
I think the solution I lean towards is that space is too big and interstellar travel never gets solved. It's a really depressing thought though so I still like to pretend that it will happen someday.
It may be a mistake to say never. I don't think walking on the moon or instantaneously seeing/talking to anyone on Earth whenever you want to seemed any more possible to humans living 1,000 years ago than interstellar travel seems to us, today. It's like how it took modern humans a couple hundred thousand years to figure out fire, but we went from not even knowing of the existence of 40% of the planet's landmass, to sending cameras to Neptune in under 500 years. Interstellar hopscotch may be something we don't figure out for a long, long time. Or it could be within reach in a (relatively) short amount of time. Either way, just because something seems totally impossible, it doesn't mean it will always be so. It only takes one brain to make one leap into a completely new idea to change everything.
It really could tho. Maybe not for us tho. We could easily get to 10-20% the speed of light. Then we could send a large group of humans on that ship to another star.
Just finished the book All Tomorrows and it is insane and makes you wonder about if we really want to contact extraterrestrial life even if they’re “friendly”. They could see us like we see grass when we mow it, changing and “destroying” it in an effort to make it more beautiful and help it grow.
"The Great Silence" might better be renamed "The Great Rejecting Assumptions." The "Rejecting" part is for trivially rejecting any evidence of possible visitation without adequate investigation (i.e. dismissing UAPs) and the "Assumptions" part is for trivially rejecting any unknowns in physics and technology which might enable efficient travel between star systems (i.e. assuming our _current_ limitations will be perpetually limiting). The paradox is only a paradox when employing assumptions which may not be true.
I LOVE Carl Sagan. 💘 The movie Contact came out when I was in middle school and it changed my life. Not even exaggerating. My cats are named Carl and Sagan and Annie. (For Anne Druyan, who Carl called "Annie") "The Demon Haunted World" is easily one of my 5 favorite books ever. Lol, just nice to run into someone who appreciates him too. 🤓⭐🪐🌎
Given the lightspeed barrier, and that humans have only been looking for signals for such a tiny fraction of time, then to me it is no surprise at all that we do not see any signs of intelligent life. Such signals may have long since come and gone, or may still be thousands or even millions of years away from reaching us. All I need to assume here, is that intelligent life is a relatively rare event, at the cosmological scale, which I think is a not unreasonable prior.
There was once an impenetrable barrier called "the speed of sound". We clever humans figured out a way to travel beyond that barrier. Perhaps in the future we clever humans will discover how to cross the lightspeed barrier. If we do, then I submit others will have done it before we did. Where are they? Maybe they're already here, studying us as we study apes. Apes aren't necessarily aware of us just as we aren't necessarily aware of a more intelligent extraterrestrial species. It doesn't seem that improbable to me. The only thing preventing us from seeing this might be human ego.
@@quantumac Comparing speed of sound with the speed of causality (you know it's not really the speed of light, right?) is pretty silly brah, but I'll leave it at that, because you are conflating science and philosophy, and for sure, in a Universe that may well be infinite, who knows what is actually possible, including of course, the Flying Spaghetti Monster.
@@MrBendybruce There are loopholes. Now, if any of them can actually be used (heck if any of them are anything but quirks of looking at the math in a certain way) is still up in the air. But if the equivalent of FTL travel is possible ET would still have to be actively hiding from us to be here but not seen.
Wow, caught a Godier video 5 seconds after it was posted, I'm pretty proud (just coincidental - I don't use the notification bell or anything). Coincidence? ..I think it was ALIENS!

We could barely detect a nearby civ like our own. We should only expect to detect aliens if they were A) ridiculously common, or 2) ridiculously flashy/noisy. We should expect any non-ridiculous ET to be invisible to our current telescopes. (Even if many ETs made lots of Von Neumann probes, and they all passed through this system, we still shouldn't expect to see one very often.)
@@MH-up1xe exactly! we expect to be looking for something large like the probes we make and send into space. Maybe if other civilisations exist, they might use millions of microscopic nanotechnology type probes instead of a few large ones. Alien life could be staring us in the face but we might not recognise it for what it is.
Kind of weird when i think an alien civilization looking at us now, but will be looking at us in the past. How would one species of alien know who we are now than looking at dinosaurs (If they're 65 million Lys AWAY)
One of their vast fleet of AI probes would focus in on the dinosaurs. And the watchers would be staggered to find that another planet also had crazy monsters roaming the world in its prehistory. And think there's point going there to meet what has surely by now evolved into intelligent life because we'd arrive millions of years too late.
A philosopher once asked, "Are we human because we gaze at the stars, or do we gaze at them because we are human?" Pointless, really..."Do the stars gaze back?" Now, that's a question.
What about a tidally locked gas giant orbiting a red dwarf with habitable moons? If that planet is in the habitable zone, wouldn't that moon's assumed tidally locked orbit around the planet evenly distribute the heat of the sun, further enhancing its habitability?
That's where the thinking is going. The problem is in detecting the exomoons, it's extraordinarily difficult and to date there are only a few candidate detections. We need bigger telescopes.
It is always interesting to ponder such things, especially when considering the infinite possibilities. Although I am on the side that there is life out there, I cannot deny that it is possible that we are alone. We could be the first planet with life and we could just as easily be the last. Even when speaking about infinite universes, one would have to accept the possibility that ours is the only one that came to be in such a way that life was possible. Though I do not subscribe to that. We could even be on verge of life from another universe crossing over into ours enmasse because they have found a way to escape their dying universal dimension. The possibilities are endless.
This is what I think. We’re probably not alone, but the equation for intelligent life might be actually so stacked against it that there could be no other else where.
I'm fairly convinced that there's a place at the end of time where all of the waste heat and light ends up. If information if somehow fundamental to existence, than this place/object at the end of time should look a lot like a singularity with this universe iteration information encoded on it/in it. Imagine civilizations from across time meeting there, functionally the end of the universe as we know it.
All that waste heat and light will end up at MilliWays, the restaurant at the end of the universe !! ..... where an Octurian cow will suggest to you which parts of it will make for the best dining :D :D :D
What if that's what black holes are? They're just deconstructing matter and concentrating it back into a singular point. Probably not accurate, but it's a thought
Apparently, that study on red dwarves flaring at their higher latitudes has been largely upheld. That's great news for the prevalence of potential life bearing planets.
That's my sense too. A total reversal of a trend. I must have made 10 videos over the years citing the dropping chances of red dwarfs being habitable and all of a sudden they came roaring back to the table.
@@JohnMichaelGodier Now let's combine that with all the studies that indicate that a tidally locked planet in a red dwarf's life zone could support life. Now they become even more promising. For other reasons, they'll never be as welcoming as a rotating planet under a mid-mass main sequence sun. But they are, as you say, back on the table. That's at least 70% of the stars in the universe! Quite a haul.
Fermi Paradox forever ❤ I would also LOVE more videos on cloning and updates on bringing back extinct species. Easily the best channel and I can’t sleep without you now!
You know all those sci-fi novels and films and games where there's an ancient precursor race that dies out, but seeds the universe with tech and ruins? It's kinda rad to think that in this universe, WE are that ancient race.
I find it hard to believe a species could achieve any level of technology and not have curiosity. Virtually every vertebrate species and some invertebrates like cephalopods display curiosity. It's an essential part of intelligence. A creature without it would never progress past being a worm.

The origin of Eukaryotes and the theory of endosymbiosis could be one of the keys to the fermi paradox. The theory goes that a prokaryotic organism engulfed another prokaryote, and they lived together in a symbiotic relationship. The engulfed prokaryotic bacteria eventually became our mitochondria giving rise to eukaryotic cells (the cells humans and plants are made of). I wonder if at some point, AI will become a 4th branch on the tree of life, engulfing biological humans or plants to preform some function and benefit them creating a 4th evolution of life.
*Love you videos so much. Makes me sad AF, though that I'll never get to explore other plants and travel to other solar systems and see aliens. So depressing lol* 😭😭
In short, inspired by all of these ideas, including the Great Filter, I have an idea of my own that has a celestial analogy. Quite simply, we're as far from other alien civilizations in TIME as we are by distance. The celestial analogy is a comparison between the collisions of alien civilizations to that of galaxies. When galaxies collide the stars do NOT. They're too far apart. Likewise, there might have been civilizations right near us, but they've died out. Now is OUR time in the sun, but we'll be gone one day too. And a new civilization will arise in THIS neighborhood. We're as far away in TIME as we are by DISTANCE from alien civilizations!
It's kind of a realistic take on our place in this universe. A bit bleak, a bit cyclical, but a believable scenario. I still wonder if we'll ever reach an Interstellar level of travel.
There is a big difference between extraterrestrial life, which has to be abundant give the size of the galaxy, let alone the universe, and intelligent extraterrestrial life, which while likely, could be exceedingly rare. Intelligence is not an evolutionary necessity for survival of a species. On Earth of the billions of organisms that exist or have existed, exactly one has been what would be considered highly intelligent. Could easily be a very rare exception.
Only one? I count at least ten currently existing. Perhaps our anthropocentric view driven by religious falsehoods is the reason we are blind to find other types of intelligence.
It does not have to be abundant. The conditions on earth might be unique and the chance of something like that being repeated vanishingly small. Statisticians cannot possibly know the actual chances for life popping up, so who knows.
I wonder if there were any intelligent dinosaurs Perhaps one that was on the path *Imagine if they rock up in a thousand years* ...as in they left Earth before the meteorite hit
@@godamid4889 really, 10 that are capable of planning or conducting space exploration? 10 capable of producing technology that could be detected through SETI or other searches? Please name them. The point is there could be millions of planets with life forms intelligent as dolphins or gorillas and we will never know. It would take a species at least as intelligent as humans (and probably much older) to create any type of signature that would prove other life exits in the universe.
We've only been actively searching for not even a full century. That time is almost insignificant compared to the eternity of the universe. We would have been very lucky to find any life within that short amount of time.
My absolute favorite idea is time dilation I’m so happy to hear it on the list! I’ve always thought heavy about that one, to me it makes the most sense without having to call in a big idea like the multiverse.
It's not as if these relativistic spacecraft would have winked out of existence, though. We'd see (assuming we had the technological capability) objects moving at very high speeds. They're not jumping to the future. They're going through time at a rate of 1 second per second, like everything else. Hoping to get a clarification, from JMG, of what he means by this one.
I cut that entry down too much in editing. The idea is that relativistic aliens with the intent of time dilation would probably do it in intergalactic space. That's a detection problem because you can't know just where to look, especially with today's targeted SETI programs, and if you did unless they were beaming out an extra huge signal we'd never know they were there.
I'm honestly discouraged with the idea of finding anything. When you look at the situation Earth is in it is very rare. We can't even find a planet within 20% of our size around a similar star. I believe liquid water 93 million miles from a star is exceedingly rare in our current universe. I believe we will find this out and our race will never have contact. 13ish billion years may be very early. When I look at the life cycles of these things like blackholes and stars. 13 billion years is really not that long at all. I believe our universe has chilled out enough to allow our life to emerge but I fear it is the monkey with type writers situation. Billions of light years of matter and voids and dark matter and things we don't know, the right things ended up being able to happen and here we are. I think chaos accidently spat us out and we get to struggle until chaos claims us back.
@@freezatronin a weird way I think I can take solace in that. Even in an infinite universe, I'm unique just through being myself. It's kinda lonely though tbh
When you look at human history, maybe its a good thing we are alone . War, Greed, envy, mistrust, hate. These are qualities the universe can do without. These are qualities I can only hope are unique to this planet.
Boo hoo. I tend to focus on the good humans do. I'm not one of those "humans are the worst things Earth has ever produced" snowflakes. Being negative is so counterproductive. I would hate to be miserable like that all the time. Always finding bad in thnigs. Must suck.

@@ddmarty Its people like u that will atract a dangeous species to wipe us out im all for contacting aliens but not before we can defend ourselves and study them good thing u are not a scientist
I know it may sound silly, but I really wonder if there is something to the whole Star Trek prime directive thing. There are more advanced civilizations, but they’re not making contact because it would be dangerous for us and them. Maybe even a lesson learned the hard way with a contact that did not turn out well. Possibly, We have been deemed too primitive. They’re just watching to see if we evolve.
I was kind of thinking along this line. Maybe there is something they are watching for before they make contact. Some sort of technology event that triggers the contact. I think in Star Trek it was warp drive. The aliens are fine with us sitting on Earth, but want to catch us before we make a surprise visit to their planet.
Distance is a matter of perception. If it took you a week to travel across the universe then you wouldn't believe it to be very large. We used to think the Earth was huge and look at us now?
What's funny is, people keep forgetting about the Zimbabwe school encounter. When all those kids saw the UFO land and saw the beings come out the UFO. And they were 3ft away from the beings. They had the kids draw what they saw and they extensively interviewed them. That was like 19 years ago and they are grown now and they did a documentary on this where they gather like 6 of the kids who are now adults tell their experience and how the beings telepathically spoke to them. How much more evidence do you need after something like THAT!??????? The movie documentary is called "The Phenomenon" ... literally the most amazing documentary out there. This suppose to go down in the history books globally. And should be globally publicized.
How much more evidence than that? We I'd say some evidence at all would be nice. As in any actual evidence of any kind. All we have is a story. Do you have any proof that they're not just making it up?
Witness testimony, even when detailed and emotionally charged, isn't considered the most reliable form of evidence, especially in extraordinary claims like alien encounters.
I've always wondered why I never hear anyone talk about the literally Hundreds of temporary ultra bright mini start we created in space, with not pattern, whos light is traveling out in all directions from the many hundreds of H-bombs we detonated in outerspace from the 50s through the 60s. These ultra bright, omnidirectional bursts have been spreading out presently at a distance of over 70 light years, an will continue to go out at the speed of light in every direction for millions of more years
It occurs to me that when an object(spaceship) travels at relativistic speeds it's mass increases. As its mass increases its gravity increases. Since we are now beginning to detect gravity waves, couldn't we with a sufficiently sensitivity gravity wave detector be able to find ships traveling through space at relativistic speeds?
one question John Michael.. the recent launch of the JWT. If it was to spot something of an undeniable techno signature.. would it be even made public ??
Thanks, lots of great ideas and thoughts! I’d say that if there’s life in a different universe or life beyond our visible and reachable universe, that does not qualify as making us not alone. Here and there in other galaxies but none in our own - I’d say we’re still alone. The real question is, are we alone in this galactic neighborhood at this time? You might even say that even so, we are still alone, alone on this planet because this is what we are adapted to and this is the one place we can live easily and comfortably, and it’s unlikely we’re going to find others that can come here and live just as easily as us in this spot. About the possibility that that other life isn’t curious or is uninterested in other life. We know that evolution works with variation and we know that every species on our planet is full of variation, including humans. Some of us have no curiosity, others have great curiosity. There’s every reason to think that other beings will be the same way, and some individuals might not be curious but definitely some of them will be. Radiodurans - undoubtedly there’s a good explanation for its high radiation tolerance but we just don’t know it yet. Earth has probably been exposed to massive radiation at various times from nearby supernovas or a hyperactive sun. And then there are the natural sources of radioactivity that some life might’ve adapted to and thereby acquired efficient mechanisms of tolerance. And perhaps other types of substances or processes might be present in some environments, that damage DNA and other life molecules and require nearby organisms to adapt. I wonder if estimates have been made of the number of earth-like planets out there by estimating what are the differences in our ability to detect them versus the ability to detect larger exoplanets, and comparing that to the number of earthlike planets we’ve found versus the number of larger planets we’ve found but that would not have been found if our instruments were less sensitive to the same degree.
I assure you, relative to the size of the observable universe, to say that life is exceedingly rare is a huge understatement. Out of an estimated 10 septillion planets, only a few thousand have or are capable of supporting life and sadly, humanity is unlikely to detect any of them. I'll bet the farm on it!

Just so you know John. Most of us wake up the next day and listen again so we can see what we missed after falling asleep. Surely I am not alone in this?
Lol, I actually hear it in my sleep. I have a headband with speakers inside, and I play a randomized playlist of both channels. I do listen to new event horizon videos on my drive into the office though. Some of the guests are just awesome!
You are not alone my friend. I just find it amazing that so many of us listen to John’s videos twice at the end and beginning of the day. One to relax to sleep and the other is listening with intent when we and our mind are awaken. It’s a most curious thing. But true it is, I’m relaxed listen to the video with interest the entire time I’m falling asleep when listening in bed.
I do the same.
LOL! Same here!
❤ always !!
I have always been pretty convinced that time is the solution to the Fermi paradox. Considering the vast VAST amounts of time we are talking about it seems incredibly unlikely that multiple intelligent species would be around at the same time.
Like just stop and think about it. Let's say a species rose up right when earth was formed and they thrived for 500 million years (which is a really REALLY long time based on how we are going). That means they still would have be dead and gone for *4 billion years* before we came along.
Yep. It's kinda depressing to think about lol.
There would be evidence of that civilization written both in the Earth's history and in the stars themselves.
Because we see no evidence of alien civilizations, we can relatively safely assume that we are alone, at least in the galaxy.
@@TheFinalChapters Exactly, and how would a space faring civilization with it's eggs in countless basket's wipe themselves out.
I disagree strongly with this. I have the opinion that finding 'intelligent' life is not really a relevant question to begin with. All we need to do is find any type of life anywhere, at all. And I mean the most basic microbial or anything of the sorts. from that single point of discovery, we can basically just assume that there *is* intelligent life out there somewhere. finding any sort of life from a non earth substrate, would be proof enough for me that there is life that is lesser, and life that is greater, than humans.
like I would have no doubts at all the second we find even the smallest undeniable proof of life. and I will stop calling people crazy who claim that see UFOs lol, (they are still crazy, or mistaken lol) but I would assume that it is possible that if there is life, there is more advanced life than us, and they may have technologies that we consider impossible today.
I think this is valid - that the size of time as well as the size of space make the likelihood of anyone finding anyone at the right time via comparable technologies a tiny needle in an astronomical haystack. Still, this isn't a question of one civilization detecting one other civilization, but rather this should be multiplied by some quantity of technological civilizations out there, at least the ones strewn across the area of space relevant to us. If the chances are one in a gazillion of finding intelligent life but there are a gazillion of them out there, wouldn't those odds balance out at some point...?
I find it hard to believe that there's no other intelligent life out there. The universe is simply too big for intelligent life to have only happened once. The issue is that same immense size though. We might simply be so far away from other intelligent life that we'll never be able to meet or even see them.
I’ve listened to all the fermi videos across channels, desperate to find my own educated conclusion. I really don’t think there is traditional aliens. If anything I think there is creatures living in oceans that may be intelligent like many of ours, just not in the same way as us and no real way to know they are there and not intelligent enough to look or know.
True. The problem is that this was for several centuries the basic argument for mermaids. Ocean is big, there's gotta be mermaids somewhere! The key issue is that we still don't really know what life is ir how it came to be here. Certainly every other place we've visited is 100% sterile as far as we can tell.
We really need to find life somewhere else before we can make this claim.
Also, the lazy claim that "nature abhors a one-off" simply is not true, regardless of how many times JMG repeats it. There are one-offs all over the place just on earth, at least in some sense. Only one Big Butte. Other places a bit similar to it, but it's recognizable and unique in many ways. One Barrier Reef. One Kilimajaro. One London. Etc. Basic physics repeat endlessly on a simple pattern, but not the expressions of those physics.
The same "science" that led JMG to say this is also telling him that every snow flake is unique. It's almost a trope. But both things can't be true at once.
Or we may be trivially rejecting evidence which indicates another species has already figured out how to traverse the immense distances and has been visiting our world for some time (i.e. UAPs). Perhaps they are observing us just as we observe less sophisticated species here. We humans don't march into ape areas and announce "we are a superior species and we have come to be friends." Apes aren't really capable of understanding our motives anyway, just as we might not be capable of understanding the motives of some other intelligent life.
Yeah and I hope we are stronger and enslave them.
Humans are a anomaly in that we're the only thing ever that created technology and the ability to travel into outer space. The living organisms that are on other planets are animals that just act on instincts. Hum

Personally I find a combination of the rare earth, early in the game, rare complexity and intelligence, and the fact that we’ve only scratched the surface of searching to be a satisfactory answer to the Fermi paradox
It’s sad to think there are lifeforms who may have developed in a galaxy filled with life - so their civilization are able to confirm alien life - meanwhile us humans are so far away from others that we are essentially alone, left to ponder the question that can never be answered, simply because of a dice roll that had us created in a pocket of space with only us in it.

They find nothing the whole time and finally get to the other end of the galaxy where they discover an inhabited technological planet, only to discover it is inhabited by humans who discovered wormhole technology five thousand years after they launched.

It's remarkable, how quickly we can expect any species to evolve once it invents computers and aims for artificial intelligence. Evolution will effectively become a vertical line on a graph of the subject. All physical processes will be mastered in short order, and good luck figuring in what direction such a species might head.

I like to imagine what would have happened if the dinosaurs had never gone extinct? It's entirely possible that reptiles could be the dominating species on Earth. Environmental factors are everything and they are the deciding factor in which classes of organisms continued to evolve into the dominant lifeform. Who knows what has happened on distant worlds with different environments? I love this kind of thinking, I find it exciting and thought provoking. Thanks John 👍
I like to imagine what happened if some dinosaurs DNA got blown out into space when the asteroid hit. What if that DNA was able to grow in an environment?
Dinosaurs didn’t go extinct. We just call them birds which are very intelligent. Also dinos aren’t reptiles. However stu Art, your point is well taken. Those dinosaurs lived for over 100 million years. It’s just that the environment was not maybe “challenging “ enough to get them to the techno level. Or, maybe it was and as you know, 99% of fossil evidence is missing so we won’t know if they were that advanced
@@Boogaboioringale This depends on your definition of the word "reptile". There are at least three possible interpretations. One, the classical definition. Reptiles are only cold-blooded (again a somewhat contentious term) scaly tetrapods like lizards and snakes and turtles. Unfortunately, this means that "reptile" is a polyphyletic classification and therefore you can't really say what a reptile is or isn't since polyphyletic "groups" aren't really scientific. Two, the narrow classification. If you narrow the definition of reptile to be equivalent to Diapsid, then this would include lizards, snakes, turtles (which were once thought to be anapsid but we have since discovered their diapsid lineage), as well as crocodiles, birds, pterosaurs, and dinosaurs. This is the most common definition in scientific circles today, and that means dinosaurs are reptiles. Three, a wider definition. If you say that reptiles are equivalent to Amniotes, then not only are all the above Diapsids reptiles, but so are Synapsids which are mammals and our "reptile-like mammals" and "mammal-like reptile" ancestors.
Dinosaurs weren't reptiles.
The fact that dinosaur’s thrived makes me convinced that the aliens to be concerned about will be small in stature. Bigger creatures don’t need to be able to leave info to their offspring, the way intelligent humans can. I wonder if what small creature derivative could gives a run for our money, and I’d say a small bird is probably the base of the alien we should be worried about. … A bird-brain could be our eventual superior.
We can't even decisively say if we're alone in our solar system, let alone the universe. I find the fermi paradox incredibly presumptuous.
It's about intelligent life eg little green men. If they were as technologically advanced as ourselves or greater then we would've detected them in our solar system.
I liken it to this: you fall out of a plane and land in the ocean. You look around for 10 seconds and don't see any fish. “Must be no life in this here ocean!”
@@Nunya.Bidness yup easily equivalent to massive machinery
Very refreshing to see this perspective.
@@DistinctiveBlend tons of assumptions there too though. Not saying there are other civilizations in the solar system besides our own, just that we can’t definitively say that. There probably aren’t.
But it is rather absurd to assume there is none anywhere. It’s equally absurd to assume we’d be able to detect them; the scale of the universe is too vast. And us detecting them also assumes our rate of technological advancements will continue at the rate they have for the past 200 years or so.
Just assumption after assumption with the Fermi paradox. This is why I like videos such as this where they shit on it.
I've always found the term "Outsiders" to seem most appropriate for possible extra-dimensional or alternate timeline intelligences that could have made the crossing to our universe.
'Alien' merely connotates strangeness or a foreignness based upon an otherwise familiar, or at least basically recognizable substrate.
'Outsiders' confers a sense of deeper strangeness where little or nothing is familiar or recognizable. "From Outside" any known boundaries or understood constraints.
SciFi has been using the term for exactly this for a very long time. I see no reason not to use it in real science.
Thoughtful, but I don't agree. We use the word "alien" because the word "alien" is a synonym for "other" or "unknown". An "outsider" would be a being that doesn't fit with an established tradition or society, something like that. One word is much more inclusive of possible permutations than the other. "Outsider" implies that we know something about whatever or whoever aliens could or could not be.

Maybe millions of alien civilizations are all communicating with another technology like gravity waves. Maybe when we figure out how to do it we will suddenly have access to a universe wide web of information.
The issue there is the development of the kind of tech. we’d have to assume all aliens across the galaxy use that same technology and jumped straight to it. If not then we’d see the development written in radio waves. Remember the further we look out the further back in time we see.
@@timrobinson513 IMO they would use all of the good technologies. Like we currently use fiber optic and radio waves and copper wire for internet. Cell phone towers and satellites and cables. Different languages are auto translated. Different codes and protocols are auto translated. Example: Electromagnetic waves could still be used locally within a solar system, gravity waves used for intermediate galaxy distances, wormhole waves used to transmit between galaxies across the universe, maybe even something else to communicate to other universes. coders and decoders and translators automatically transfer the data to the correct form.
@@timrobinson513 However, the farther from the source the weaker the signal and more likely to get lost in the background. Ever notice how satellite transmissions tend to get wonky when the sun passes directly (more or less) behind the satellite you are trying to receive from? Now try to find the alignment to that radio beam from thousands of lightyears away and filter out the noise.
All we really know is that there are no active transmissions within a few hundred lightyears of here. Pittance compared to the galaxy as a whole let alone the universe.
JMG is one of the only creators whose videos can make me stop whatever I'm doing to watch
Dude. You have an S-tier channel. I offer thanks from the depths of my soul. You rock more than the moon. And megaman. And Lemmy.
As always a sterling video, John! Your channels (JMG and EH) are truly the brightest gems in an infinite ocean of so much entropy and junk! Question: would it be possible for you to produce a similar video the likes of which you focus on the methodological difficulty of detecting technosignatures? I know you've delved into this subject before but where I'm specifically going with my question is I sometimes think we're just barking up the wrong tree by focusing too much on astrobiology. You did an amazing interview back in October with Caleb Scharf on that subject, i.e., his biome-dataome research paradigm. It's utterly intriguing and I think you said it best in a video you posted on your channel commenting on this: It could very well be that our universe has the optimal conditions for machine civilizations-- call it the selfish machine theory? 😉 In short, once technologically intelligent civilizations pass through certain great filters, They pretty much transcended their contingent biological evolutionary pathways--And once that happens then habitability becomes a totally different issue which you've brought up before (i.e., intelligent nano dust at the event horizons of black holes and interstellar space and that sort of thing.)
It almost reminds me of my previous physics dissertation advisor the great David Ritz Finkelstein, Who already published a series of papers in the late 1960s hypothesizing that the universe might be a giant cosmic quantum computer, part of the early generation of "information paradigm" of physicists like John Wheeler who tried to derive "it from bit."
I love these what if questions and very useful information as well as hypotheticals bouncing around in my head as I relax Into the Night. I've been into this sort of thing since the early 1990s. Documentaries in general were much better back then as well as in the 1980s and 70s and John reminds me of those better times.

I think the problem with progress lies in the fact that people assume that things elsewhere function exactly like where you are now, that life forms elsewhere exactly like here, that other living beings might have similar physical features to yourself. Maybe there are different sets of rules that are opposite to how things function this side. Maybe everything we think we know about the outer side is not how it seems.
I think the solution I lean towards is that space is too big and interstellar travel never gets solved. It's a really depressing thought though so I still like to pretend that it will happen someday.
Then explain the UFOs which nations are confirming now. Including the USA.
It may be a mistake to say never. I don't think walking on the moon or instantaneously seeing/talking to anyone on Earth whenever you want to seemed any more possible to humans living 1,000 years ago than interstellar travel seems to us, today.
It's like how it took modern humans a couple hundred thousand years to figure out fire, but we went from not even knowing of the existence of 40% of the planet's landmass, to sending cameras to Neptune in under 500 years. Interstellar hopscotch may be something we don't figure out for a long, long time. Or it could be within reach in a (relatively) short amount of time.
Either way, just because something seems totally impossible, it doesn't mean it will always be so. It only takes one brain to make one leap into a completely new idea to change everything.
It really could tho. Maybe not for us tho. We could easily get to 10-20% the speed of light. Then we could send a large group of humans on that ship to another star.
Just finished the book All Tomorrows and it is insane and makes you wonder about if we really want to contact extraterrestrial life even if they’re “friendly”. They could see us like we see grass when we mow it, changing and “destroying” it in an effort to make it more beautiful and help it grow.

The "Rejecting" part is for trivially rejecting any evidence of possible visitation without adequate investigation (i.e. dismissing UAPs) and the "Assumptions" part is for trivially rejecting any unknowns in physics and technology which might enable efficient travel between star systems (i.e. assuming our _current_ limitations will be perpetually limiting). The paradox is only a paradox when employing assumptions which may not be true.
Your voice literally relaxes me so much. Also, love the videos. Keep it up 👍
This is absolute gold! 1-10 individually you could think on for days.
Does anyone else remember Carl Sagan’s description of possible alien worlds, and how they could look very different from our own. He was a classic ❤️
I LOVE Carl Sagan. 💘 The movie Contact came out when I was in middle school and it changed my life. Not even exaggerating. My cats are named Carl and Sagan and Annie. (For Anne Druyan, who Carl called "Annie") "The Demon Haunted World" is easily one of my 5 favorite books ever. Lol, just nice to run into someone who appreciates him too. 🤓⭐🪐🌎
Great show, as always. You always find new corners and wrinkles to this body of thought.
Given the lightspeed barrier, and that humans have only been looking for signals for such a tiny fraction of time, then to me it is no surprise at all that we do not see any signs of intelligent life. Such signals may have long since come and gone, or may still be thousands or even millions of years away from reaching us. All I need to assume here, is that intelligent life is a relatively rare event, at the cosmological scale, which I think is a not unreasonable prior.
There was once an impenetrable barrier called "the speed of sound". We clever humans figured out a way to travel beyond that barrier. Perhaps in the future we clever humans will discover how to cross the lightspeed barrier. If we do, then I submit others will have done it before we did. Where are they? Maybe they're already here, studying us as we study apes. Apes aren't necessarily aware of us just as we aren't necessarily aware of a more intelligent extraterrestrial species. It doesn't seem that improbable to me. The only thing preventing us from seeing this might be human ego.
@@quantumac Comparing speed of sound with the speed of causality (you know it's not really the speed of light, right?) is pretty silly brah, but I'll leave it at that, because you are conflating science and philosophy, and for sure, in a Universe that may well be infinite, who knows what is actually possible, including of course, the Flying Spaghetti Monster.
@@MrBendybruce There are loopholes. Now, if any of them can actually be used (heck if any of them are anything but quirks of looking at the math in a certain way) is still up in the air. But if the equivalent of FTL travel is possible ET would still have to be actively hiding from us to be here but not seen.
This is an excellent discussion of this topic. The most thorough, thought-provoking, and wide-ranging I have ever seen.
The relativistic time travel theory is an interesting new one I hadn't heard. Honestly my vote for best solution to the Fermi paradox.
Wow! Lots of great content dropping! Guess I'll have a new video to fall asleep to tonight, thanks John!
Wow, caught a Godier video 5 seconds after it was posted, I'm pretty proud (just coincidental - I don't use the notification bell or anything). Coincidence? ..I think it was ALIENS!
another one already?? awesome, thanks! watching this at 3am after seeing the notification in the middle of the night
as an old school youtube viewer, i appreciate i top ten list format
New favorite TH-cam channel, even bought your book :)
Hope you enjoy it!
I love these Fermi paradox videos to death. John they should name a few stars after you!
We could barely detect a nearby civ like our own. We should only expect to detect aliens if they were A) ridiculously common, or 2) ridiculously flashy/noisy. We should expect any non-ridiculous ET to be invisible to our current telescopes.
(Even if many ETs made lots of Von Neumann probes, and they all passed through this system, we still shouldn't expect to see one very often.)
What if we couldn’t see the probes like they were shielded by something incomprehensible or microscopic probes.
@@MH-up1xe exactly! we expect to be looking for something large like the probes we make and send into space. Maybe if other civilisations exist, they might use millions of microscopic nanotechnology type probes instead of a few large ones. Alien life could be staring us in the face but we might not recognise it for what it is.
A type II civilization in the galaxy would be as ridiculously flashy/noisy to us as we are to Mars.
Are we ridiculously noisy/flashy though?
@@multi-purposebiped7419 Brighter in the radio than the Sun.
love your channel, you and Issacs channel are the best on youtube, hands down. Keep up the great work! we are listening.
Kind of weird when i think an alien civilization looking at us now, but will be looking at us in the past. How would one species of alien know who we are now than looking at dinosaurs (If they're 65 million Lys AWAY)
How the fuck would something be looking at us and seeing whole ass DINOSAURS on the ground from 65 million light years away😂😂
Only the big dinosaurs would be visible. Duh 😂😂😂☺
One of their vast fleet of AI probes would focus in on the dinosaurs. And the watchers would be staggered to find that another planet also had crazy monsters roaming the world in its prehistory. And think there's point going there to meet what has surely by now evolved into intelligent life because we'd arrive millions of years too late.
oops, correction: NO point going...
A philosopher once asked, "Are we human because we gaze at the stars, or do we gaze at them because we are human?" Pointless, really..."Do the stars gaze back?" Now, that's a question.
What about a tidally locked gas giant orbiting a red dwarf with habitable moons? If that planet is in the habitable zone, wouldn't that moon's assumed tidally locked orbit around the planet evenly distribute the heat of the sun, further enhancing its habitability?
That's where the thinking is going. The problem is in detecting the exomoons, it's extraordinarily difficult and to date there are only a few candidate detections. We need bigger telescopes.
Appreciate your shows and perspectives. Always interesting brother.
It is always interesting to ponder such things, especially when considering the infinite possibilities.
Although I am on the side that there is life out there, I cannot deny that it is possible that we are alone.
We could be the first planet with life and we could just as easily be the last.
Even when speaking about infinite universes, one would have to accept the possibility that ours is the only one that came to be in such a way that life was possible. Though I do not subscribe to that.
We could even be on verge of life from another universe crossing over into ours enmasse because they have found a way to escape their dying universal dimension.
The possibilities are endless.
This is what I think. We’re probably not alone, but the equation for intelligent life might be actually so stacked against it that there could be no other else where.
Aside from the mystery of Black Holes, The Great Filter is by far the most interesting and thought provoking thing to me.
I'm fairly convinced that there's a place at the end of time where all of the waste heat and light ends up. If information if somehow fundamental to existence, than this place/object at the end of time should look a lot like a singularity with this universe iteration information encoded on it/in it. Imagine civilizations from across time meeting there, functionally the end of the universe as we know it.
All that waste heat and light will end up at MilliWays, the restaurant at the end of the universe !!
..... where an Octurian cow will suggest to you which parts of it will make for the best dining :D :D :D
All the while a hyper intelligent and depressed robot is constantly thought to be a jukebox.
What if that's what black holes are? They're just deconstructing matter and concentrating it back into a singular point. Probably not accurate, but it's a thought
You should read "the restaurant at the end of the universe" book from "the hitchhiker's guide to the galaxy"!!
Time doesn't exist. It's a man made concept. Oh, and the big bang theory is complete nonsense.
You know the perfect time of day to release your videos.
Apparently, that study on red dwarves flaring at their higher latitudes has been largely upheld. That's great news for the prevalence of potential life bearing planets.
That's my sense too. A total reversal of a trend. I must have made 10 videos over the years citing the dropping chances of red dwarfs being habitable and all of a sudden they came roaring back to the table.
@@JohnMichaelGodier Now let's combine that with all the studies that indicate that a tidally locked planet in a red dwarf's life zone could support life. Now they become even more promising. For other reasons, they'll never be as welcoming as a rotating planet under a mid-mass main sequence sun. But they are, as you say, back on the table. That's at least 70% of the stars in the universe! Quite a haul.
Fermi Paradox forever ❤
I would also LOVE more videos on cloning and updates on bringing back extinct species.
Easily the best channel and I can’t sleep without you now!
You know all those sci-fi novels and films and games where there's an ancient precursor race that dies out, but seeds the universe with tech and ruins? It's kinda rad to think that in this universe, WE are that ancient race.
Okay, buuut, there are plenty of much older galaxies.
Perhaps you might want to check Credo Mutwa on TH-cam. You are close to the truth. Shalom
Understood, I will make puzzle temples that explains our downfall. Or I'll genetically modify potato's to become the flood of this universe.
I LOVE Fermi paradox videos from you. Thank you :)!!!
I find it hard to believe a species could achieve any level of technology and not have curiosity. Virtually every vertebrate species and some invertebrates like cephalopods display curiosity. It's an essential part of intelligence. A creature without it would never progress past being a worm.
Worms are curious by nature
From the more than 10 million specie that ever existed on earth, only one specie, homo sapiens, has consciousness and can do math, music, art, language and build his civilization and technology
I have two cats. They have tested (thankfully not to its conclusion) the old adage of "curiosity killed the cat".
@@joeme3552 A fair number use tools. Some show signs of culture. A fair few are aware of their own existence and can recognize themselves in a mirror after some experience. Dolphins, prairie dogs, and meerkats all have some form of language. Dogs and other animals can count too. Our abilities are a question of degree, not kind. (not to mention that there appear to be at least two human species that were contemporaries of crow magnon.
I’ve been interested in the ufo phenomena since a child. As an adult the more I learn about space and our knowledge of it the more im beginning to the the ufo phenomena may originate from the bottom of our oceans, rather than space as many seem inclined to believe.
To think that we're alone in this infinite universe is terrifying.
We are not.
I agree. Seems we may never find out which gives most of us enough comfort to assume one way or the other.
But illogical, as life in all forms can and will evolve and thrive if the conditions for it are right.
There is absolutely zero chance we are alone. Zero. It just doesn’t make sense
And ignorant.
These are my thoughts, as I think while pooping before bed. These are my thoughts when I wake up. These are my thoughts through my workdays, as well as days off.
I can’t escape these thoughts, nor would I ever choose to. Thank you for so eloquently purveying my deepest thoughts, aspirations, and fears.
The origin of Eukaryotes and the theory of endosymbiosis could be one of the keys to the fermi paradox. The theory goes that a prokaryotic organism engulfed another prokaryote, and they lived together in a symbiotic relationship. The engulfed prokaryotic bacteria eventually became our mitochondria giving rise to eukaryotic cells (the cells humans and plants are made of). I wonder if at some point, AI will become a 4th branch on the tree of life, engulfing biological humans or plants to preform some function and benefit them creating a 4th evolution of life.
Love your videos. You and Issac Arthur rock. Rock on!
*Love you videos so much. Makes me sad AF, though that I'll never get to explore other plants and travel to other solar systems and see aliens. So depressing lol* 😭😭

Excellent video, as always. Very interesting, informative and worthwhile video.
In short, inspired by all of these ideas, including the Great Filter, I have an idea of my own that has a celestial analogy. Quite simply, we're as far from other alien civilizations in TIME as we are by distance.
The celestial analogy is a comparison between the collisions of alien civilizations to that of galaxies.
When galaxies collide the stars do NOT. They're too far apart.
Likewise, there might have been civilizations right near us, but they've died out. Now is OUR time in the sun, but we'll be gone one day too. And a new civilization will arise in THIS neighborhood.
We're as far away in TIME as we are by DISTANCE from alien civilizations!
It's kind of a realistic take on our place in this universe. A bit bleak, a bit cyclical, but a believable scenario.
I still wonder if we'll ever reach an Interstellar level of travel.
You made my Monday, John -- thanks for posting.
Crows are smart. Other planets may have crow-things. With teeth.
That's ok....I didnt need to sleep anyway..
Really enjoyed , great narration and soothing voice
There is a big difference between extraterrestrial life, which has to be abundant give the size of the galaxy, let alone the universe, and intelligent extraterrestrial life, which while likely, could be exceedingly rare. Intelligence is not an evolutionary necessity for survival of a species. On Earth of the billions of organisms that exist or have existed, exactly one has been what would be considered highly intelligent. Could easily be a very rare exception.
Only one?
I count at least ten currently existing. Perhaps our anthropocentric view driven by religious falsehoods is the reason we are blind to find other types of intelligence.
I've encountered many humans who are far less intelligent than your average dolphin😉
It does not have to be abundant. The conditions on earth might be unique and the chance of something like that being repeated vanishingly small. Statisticians cannot possibly know the actual chances for life popping up, so who knows.
I wonder if there were any intelligent dinosaurs
Perhaps one that was on the path
*Imagine if they rock up in a thousand years*
...as in they left Earth before the meteorite hit
@@godamid4889 really, 10 that are capable of planning or conducting space exploration? 10 capable of producing technology that could be detected through SETI or other searches? Please name them. The point is there could be millions of planets with life forms intelligent as dolphins or gorillas and we will never know. It would take a species at least as intelligent as humans (and probably much older) to create any type of signature that would prove other life exits in the universe.
We've only been actively searching for not even a full century. That time is almost insignificant compared to the eternity of the universe. We would have been very lucky to find any life within that short amount of time.
Its stupid to asume aliens dont exist because if aliens looked at Earth from millions of lightyears away they would also have no idea we exist
Your argument makes no sense.
Love your channel mate, it is the only channel in which I never miss a new upload, keep up the great work!!
We are not alone. The math says there is no way.
My absolute favorite idea is time dilation I’m so happy to hear it on the list! I’ve always thought heavy about that one, to me it makes the most sense without having to call in a big idea like the multiverse.
It's not as if these relativistic spacecraft would have winked out of existence, though. We'd see (assuming we had the technological capability) objects moving at very high speeds. They're not jumping to the future. They're going through time at a rate of 1 second per second, like everything else. Hoping to get a clarification, from JMG, of what he means by this one.
I cut that entry down too much in editing. The idea is that relativistic aliens with the intent of time dilation would probably do it in intergalactic space. That's a detection problem because you can't know just where to look, especially with today's targeted SETI programs, and if you did unless they were beaming out an extra huge signal we'd never know they were there.
@@JohnMichaelGodier Thank you. Makes sense. Interesting theory.
I'm honestly discouraged with the idea of finding anything. When you look at the situation Earth is in it is very rare. We can't even find a planet within 20% of our size around a similar star. I believe liquid water 93 million miles from a star is exceedingly rare in our current universe. I believe we will find this out and our race will never have contact. 13ish billion years may be very early. When I look at the life cycles of these things like blackholes and stars. 13 billion years is really not that long at all. I believe our universe has chilled out enough to allow our life to emerge but I fear it is the monkey with type writers situation. Billions of light years of matter and voids and dark matter and things we don't know, the right things ended up being able to happen and here we are. I think chaos accidently spat us out and we get to struggle until chaos claims us back.
I am definitely open to the idea that even in an infinite universe some things might only ever occur once ! :)
@@freezatronin a weird way I think I can take solace in that. Even in an infinite universe, I'm unique just through being myself. It's kinda lonely though tbh
Not sure why but I always manage to sleep through these and SEA videos . Not that they are boring just very calming . I do watch again finish .
When you look at human history, maybe its a good thing we are alone . War, Greed, envy, mistrust, hate. These are qualities the universe can do without. These are qualities I can only hope are unique to this planet.
Boo hoo. I tend to focus on the good humans do. I'm not one of those "humans are the worst things Earth has ever produced" snowflakes. Being negative is so counterproductive. I would hate to be miserable like that all the time. Always finding bad in thnigs. Must suck.
Yes yes , you do seem so positive and content . Certainly not miserable at all . No way someone could accuse you of being a snowflake despite the emotional breakdown you just had in your answer 😂😂😂
@@ddmarty Its people like u that will atract a dangeous species to wipe us out im all for contacting aliens but not before we can defend ourselves and study them good thing u are not a scientist
I get excited when John releases new videos. Very informative, In every way! Thank you
I know it may sound silly, but I really wonder if there is something to the whole Star Trek prime directive thing. There are more advanced civilizations, but they’re not making contact because it would be dangerous for us and them. Maybe even a lesson learned the hard way with a contact that did not turn out well. Possibly, We have been deemed too primitive. They’re just watching to see if we evolve.
I was kind of thinking along this line. Maybe there is something they are watching for before they make contact. Some sort of technology event that triggers the contact. I think in Star Trek it was warp drive. The aliens are fine with us sitting on Earth, but want to catch us before we make a surprise visit to their planet.
The answer is: The distances are extremely vast.
@@bb5242 And it just isn't worth it considering the time it takes.
@@bb5242 Yes that could be. The only hope I could see is we have neighbors around Alpha, Beta or Proxima Centauri.
Distance is a matter of perception. If it took you a week to travel across the universe then you wouldn't believe it to be very large. We used to think the Earth was huge and look at us now?
What's funny is, people keep forgetting about the Zimbabwe school encounter. When all those kids saw the UFO land and saw the beings come out the UFO. And they were 3ft away from the beings. They had the kids draw what they saw and they extensively interviewed them. That was like 19 years ago and they are grown now and they did a documentary on this where they gather like 6 of the kids who are now adults tell their experience and how the beings telepathically spoke to them. How much more evidence do you need after something like THAT!??????? The movie documentary is called "The Phenomenon" ... literally the most amazing documentary out there. This suppose to go down in the history books globally. And should be globally publicized.
How much more evidence than that? We I'd say some evidence at all would be nice. As in any actual evidence of any kind. All we have is a story. Do you have any proof that they're not just making it up?
@@timrobinson513 did you actually watch the documentary of the (now adults) of the kids who encountered it? If you haven't I highly recommend you to.
Witness testimony, even when detailed and emotionally charged, isn't considered the most reliable form of evidence, especially in extraordinary claims like alien encounters.
As Carl Sagan famously said, "Extraordinary claims require extraordinary evidence."
I've always wondered why I never hear anyone talk about the literally Hundreds of temporary ultra bright mini start we created in space, with not pattern, whos light is traveling out in all directions from the many hundreds of H-bombs we detonated in outerspace from the 50s through the 60s. These ultra bright, omnidirectional bursts have been spreading out presently at a distance of over 70 light years, an will continue to go out at the speed of light in every direction for millions of more years
There was only one orbital detonation.
Every Video I look forward too just amazing as always. The voice is just amazing

Thanks for the video. Not a fan of lists of ten, but your content is always top notch, thanks again.
We are, even now, an incredibly rudimentary form of intelligent life.
I agree. Humanity, as a whole, seems pretty fucking stupid and archaic imo
@Andy Witmyer No way
I like your videos. You uploading more often is a great improvement. Just don't feel pressured to upload like everyday.
Also, have you known that in December 2021, they found out that exoplanet HAT-P-11b has a magnetic field.
It occurs to me that when an object(spaceship) travels at relativistic speeds it's mass increases. As its mass increases its gravity increases. Since we are now beginning to detect gravity waves, couldn't we with a sufficiently sensitivity gravity wave detector be able to find ships traveling through space at relativistic speeds?
one question John Michael.. the recent launch of the JWT. If it was to spot something of an undeniable techno signature.. would it be even made public ??
Thanks, lots of great ideas and thoughts!
I’d say that if there’s life in a different universe or life beyond our visible and reachable universe, that does not qualify as making us not alone. Here and there in other galaxies but none in our own - I’d say we’re still alone. The real question is, are we alone in this galactic neighborhood at this time? You might even say that even so, we are still alone, alone on this planet because this is what we are adapted to and this is the one place we can live easily and comfortably, and it’s unlikely we’re going to find others that can come here and live just as easily as us in this spot.
About the possibility that that other life isn’t curious or is uninterested in other life. We know that evolution works with variation and we know that every species on our planet is full of variation, including humans. Some of us have no curiosity, others have great curiosity. There’s every reason to think that other beings will be the same way, and some individuals might not be curious but definitely some of them will be.
Radiodurans - undoubtedly there’s a good explanation for its high radiation tolerance but we just don’t know it yet. Earth has probably been exposed to massive radiation at various times from nearby supernovas or a hyperactive sun. And then there are the natural sources of radioactivity that some life might’ve adapted to and thereby acquired efficient mechanisms of tolerance. And perhaps other types of substances or processes might be present in some environments, that damage DNA and other life molecules and require nearby organisms to adapt.
I wonder if estimates have been made of the number of earth-like planets out there by estimating what are the differences in our ability to detect them versus the ability to detect larger exoplanets, and comparing that to the number of earthlike planets we’ve found versus the number of larger planets we’ve found but that would not have been found if our instruments were less sensitive to the same degree.
I assure you, relative to the size of the observable universe, to say that life is exceedingly rare is a huge understatement. Out of an estimated 10 septillion planets, only a few thousand have or are capable of supporting life and sadly, humanity is unlikely to detect any of them. I'll bet the farm on it!
Fantastic topic, JMG! 😃
