I really hope you enjoy this supercut! Parts of 12 different episodes have gone into this one, plus a lot of extra content made specifically for this video. I know this is a very long video, so I'm curious to know how you get on with it, so I can gauge whether I should ever do something like this again in the future. Thanks for watching! Alex
Every so called "scientist" that does not see that the universe is a living thing is just a mechanic. His mind can only process the obvious parts of life before his eyes. Everything is alive. Life does not end at the other side of a cell's membrane. A city is an organism too. There is no isolated system in the universe. It's systems within systems, overlapping each other. God is life itself. Everything in life is connected. We are part of a greater being. Religions are just different languages, they are an attempt to communicate this insight to other humans. With science getting more and more of the picture (macrocosm, microcosm), and people getting educated about it, it will be easier and easier for everyone to understand it. For that:☮️, you have to see this:☯️
Hello Alex, I’m a grandma from Manchester UK and I really enjoy your videos. I think they’re extremely well done and your delivery is perfect for me. You explore and explain things with a direct, clear manner. Plus, I enjoy the topics you share - even in my sixties I still love to learn.
This has given me nearly 2 weeks of content to fall asleep to. Everytime I go to bed I resume the video to the point I last remember. Theres few things more comforting in my life than being able to watch this channel and a few other similar ones most nights.
@@stevecooper6515 lol, I don't think OP meant to say it's so bad ' can't stay awake while watching it. At least _I_ didn't mean it that way. It's that we intentionally only watch the video when we're about to sleep, for me because I'm always busy for most of the day and I truly enjoy the content so I just have to squeeze in time to watch it.
Astrum, your voice is so calming that I always try listening to them to go to sleep, the only issue is that the content is so interesting I can’t help but to stay awake so that I can enjoy it in it’s entirety. By far one of my favorite channels man, please keep them coming.
Going all the way back to the 1970s, I was confident the world could cope. But the past 5 to 10 years in this country have changed my mind completely. We’re deeply awash with masses of people who can’t seem to handle or process much of anything. We seem to live in Gooberville, and there will be no quick way out of it.
Have to agree, there is no unity, there is no empathic ability, there is no self reflection, and behind all of that there is no rationality or critical thinking. The older I get the more the percentage estimate grows in my mind of children in adult bodies.
People have survived concentration camps, tortures, world wars, slavery, and the bubonic plague just to succumb to the knowledge of alien existence... Seriously?
@@kurt7937 This. General look and feel of western society is vastly more degenerate than it was even one hundred years ago. I don't believe in conspiracy, but our use of capitalism and marketing has really affected our values and priorities. I think this will be our undoing as a species, unless something brings about a complete flip in that regard. Unfortunately as Mark Fisher once said "it's easier to imagine the end of the world, than the end of capitalism". Perhaps a reset of society via a natural disaster or mass pandemic will nudge us into a better direction.
Hey Alex, thank you. I hope you see this and know how much you've helped so many. It's neither here nor there what I, or anyone else is going through, or has been through but your contributions have helped countless people get through some seriously tough times and been a wonderful escape from our struggles here on Earth and pointed our eyes toward the skies. Toward things greater than ourselves and anything we could possibly imagine. Much love, bud.
Once I understood the scale of the observable universe I came to a realization that discovering or contacting any potensial extra terrestrials was a slim one. Then I also realized the the scale of time and how small we are in that dimension as well. Even within our own galaxy there doesnt seem to be any reasonable setting for us to make any contact with others if they exist, have existed or will exist. In astronomical timescale, we just came into existence and are likely to be just about to vanish. Lets just make sure to fully appreciate the moment as long as it lasts.
I'm afraid the basis of your analysis is fatally flawed, the evidence suggests we have been "making contact" back and forth for thousands of years, you think the fantastical tales of mythical creatures and Gods was some elaborate mushroom trip? This simply cannot fully account for the way words like Demon were created which in Latin means, "warn away from" you think men formed our entire society around keeping these warnings alive for thousands of years, century after century, for all this time!? Think about the ridiculousness of that, those men saw something that completely altered their perspective on the nature of society itself and enacted a multiple millennial plan to get word to us in the modern age that these creatures brought nothing but pain and suffering down upon them, they poured all their lives work into getting the let out in such a way no one ever thought of before or since! That's too much dedication not to heed their warnings. It happened, we met them before, it went... Poorly on every occasion. So I wear the mantle of the people who no longer speak with us, who left us only subtle clues, because there's going to be a reveal soon, and Humanity has the right to know if they've been played and we have a moral obligation to pursue restitution of the highest for the atrocities left in their wake! Of course, this may never bear fruit, but it's gotta be the main reason why they haven't invited us into the Fold yet, Imagine having to explain to hundreds of other societies that you interfered with a developing world and altered their entire societal model because you were so bad at it that thousands of years later they still want a piece of your A$$! We'll likely be boycotted and further oppressed by any such Federations just so they don't have to have their dirty laundry put on display, the moment they set foot on our world, was the day they effectively wiped out our species, we never had a choice because of them, I want justice for my Planet!
at least out of all the comments there is someone who actually gets it . congratulation to you! and as terrifying as it is most likely with all the evidence we have at this time, and knowing how amazing the fact of life becoming from a chemical broth...and the stretch of time we have to be ok with 1: not knowing ,and 2: excepting that more likely then not we are alone! means that this is just a wonderful moment in time meant to be enjoyed!
They Shadowbanned hypothetical beings from space negative talk about their theoretical motivations, what's that tell ya huh!? I gotta be nice to some mythological being from the stars!? Make that make sense hmm!? You not telling us something!?
100% i really wish people understood the percentages of chance and how much time has passed exclusively to earth. I don’t think our brains really conceive of the number 1 million. Let alone 4 billion years and this planet has to be perfect for 4 billion years to only begin life at the very very tail end of that. Remarkable. It’s certainly not impossible others exist, as we do exist. It is still insanely unlikely we ever make contact. Intelligence isn’t always the most adaptable. Billions of creatures are alive just as we are, yet we are the only ones to get off the rock.
This was really interesting, but the question "What Will Humanity Do If We Ever Discover Aliens?" was barely touched? The title should be: "What we know about-, and how we look for alien life"
@@Vicus_of_Utrecht in such a claim it is most likely the first since in the grand scheme of things the universe is still in its infancy. The eventual heat death of the universe is predicted to take place trillions of years from now. Let's presume this to be correct. Then the scary scenario exists that we have to carry the torch of consciousness out into the vast expanse or it will (most likely) die out with a wimper.
More likely “our galaxy”. There will be life elsewhere in the universe but sheer distances mean we can never meet. Not to mention the temporal issue. We are here before or after they were there.
@joesands8860 Think about the infinite vastness of space. If we are the only intelligent life in all that, that is a horrifying prospect. When we go, space would be completely void of life. Just meaningless, endless nothingness.
Ants would say humans are really large and really indecent pests who do not have the decency to watch where they step and are a warlike being who try to annihilate us. Is there any wonder why we sting the hell out of them?
I got really high at work one time and me and my co worker stood staring at an ant hill and we were determining which ones were Foreman and helpers and which one was the main superintendent of the ant hill project. You'd see one bigger ant going around and checking on different groups of ants and that ant would go and talk to another ant and that ant would pass on the information to the helpers. Then, we'd cause a collapse of part of their hill then watch the workers being directed to put their dirt in certain places and developing new tunnels. If you looked really close you could even see tiny blue prints the bigger ant was carrying under it's arms. It was so hilarious we stood there for 30 minutes laughing like crazy.
We should learn to get along with each other even if there aren't aliens out there. Being this aggressive as a species is no longer necessary, but we still take aggressive approaches to solving our problems in situations where it would be better not to be.
Outstanding! Many thanks for the long form today, needed something to listen to while getting chores done and getting to learn stuff while I do it makes it win win! I will gladly watch more of these.
The scale was originally designed in 1964 by the Russian astrophysicist Nikolai Kardashev (who was looking for signs of extraterrestrial life within cosmic signals). It has 3 base classes, each with an energy disposal level: Type I (10¹⁶W), Type II (10²⁶W), and Type III (10³⁶W). Other astronomers have extended the scale to Type IV (10⁴⁶W) and Type V (the energy available to this kind of civilization would equal that of all energy available in not just our universe, but in all universes and in all time-lines). These additions consider both energy access as well as the amount of knowledge the civilizations have access to.
Let's imagine that a thug watches these videos as well. Next time in court: "Your honor, in my defense, it must have been a koala that has the same fingerprints as I have." ...
As always, informative and beautiful. I almost shed a tear towards the end. How can so many people still want to cause suffering by being so violent instead of working together to form a more perfect union? If only there was a way to skip ahead to the part in our existence where we are part of the Galactic Union and living the dream!
Awesome commentary, extremely thought provoking. I have heard a lot of the arguments and theories before but to have them presented together in a well thought out progression was very helpful. Thanks for your hard work, well worth listening to the whole way through, look forward to further content.
Note on the lack of a dynamo for a magnetic field: Tidally locked planets are not without rotation. They do in fact rotate because there would be a night/day cycle based on theplamet's yearly orbit. Tiddal locking is not due to rotation ceasing, but by the rotation matching the orbit around the star. Additionally, due to the close in orbits of a tidally locked planet, its year would be much shorter than our Earth year, potentially only a couple weeks or even a few days. Would this be enough of a dynamo for some, all be it weaker, magnetic field?
Great explanation. It is one of the most common misconceptions that people have about tidal locking. Like most people think far side of the moon or the misnomer "dark side" of the moon is not at all lit by sun. But that is not true. Moon just rotates at the rate at which it revolvves around Earth.
How would there be a day and night cycle if a planet is tidally locked to a star? One side would be facing the light source all throughout the yearly orbit
You had me at: About Life Beyond Earth. I enjoy your content very much. I share what I can synthesize with my sons, aged 7 and 5. Keep up the good energy!
I took my nieces through both Cosmos series after the oldest got interested in the book version by Carl Sagan I had on the shelves. They absolutely loved them and are 6 and 11.
I'll quote somebody else "when you walk close to an an anthill, do you stop and try to communicate with the ants!? Do you exchange knowledge and technology with them, or do step on a few and be on your way!" This will most likely be the outcome of discovering aliens, we have this weird thing where we projecting human traits onto non-human organisms, what we consider "aliens" might have a totally different agenda than we could ever imagine...
Would you step on or walk over a dog or a kangaroo or koalas...I think at the very least an ant who has made a nuclear bomb, watches sport and imagines movies and literature will at least be studied as smart humans study ants
The analogy relies on thinking about how a human would behave around ants and calls it the most likely outcome, then dismisses all other outcomes by claiming that we are projecting human traits onto non human organisms. ????
How would you know that that's what would happen tho? Saying for sure that that's what would happen is just ignorant and lazy. Ants don't have advanced tech. We do. Ants don't cultivate crop and animals for mass consumption. We do. Ants don't have the world wide web. Who does tho? Humans. Hell humans have left the planet. We do more than Ants, were the dominate species, not Ants. Such a lazy and frankly stupid analogy.
Amazing video. I just recently discovered your channel and you've already hit the top of the list. Looking forward for everything to come as I make my way through your older videos.
That's one of the best videos I've ever seen on UA-cam. It's a fantastic recap of our knowledge on the topic and of most hypotheses. I just think that talking about Fermi paradox answers would have been nice. Talking about the big wall, and all the interesting propositions for answering the Fermi problem. Not all of them, but all the interesting ones. I find that the big wall that any civilization reach but can't pass really fascinating. An event that happens no matter what and destroys the civilisation. But fantastic video, you're one of my favourite youtubers
Even if the galaxy is bursting with planets full of life, we are still alone and we’ll be alone probably forever. Distances in between these worlds are just too immense….
Agreed. There doesn't seem to be any viable means of traversing interstellar distances, even in theory. We are therefore essentially isolated, and alone.
yes but if/when we reach 5% the speed of light , that means our (robotic) ships can investigate all planets in the milky way in less then 100 million years while that's an enormous amount of time just realize the milky way is roughly 100 times older.
OP is correct, just like we'll never colonize Mars. The reason we exist is because the Earth is a self sustained ecosystem, without it we eventually die. Not to mention humans are more interested in war, we'll destroy ourselves long before ever exploring another solar system....LONG before.
When he said "Unless we intend to just throw insulting messages at each other through the void" All I could think of was.... " HEY!! " -" H E L L O ? ! " " WHAT'S YOUR NAME?! " -" T O N Y ! " " F*** YOU TONY!!! " ( If you know.. You definitely know 😂)
We would be happy with bacteria. It would whisper of more to find.... We most seek life, though, that will "respond" to us. That is our... heart's desire. Thank you for this message, and including the part on aliens. I listened all the way through, when I did not intend to, originally. It was very well done.
1:33:04 this is actually most likely a Boeing 737. The flashing sequence of the lights and flight path at that time both match a certain flight taken by one of those planes.
Hey Alex, at 7:51 you say photosynthesis has evolved dozens of times, but my understanding is that it occurred only once. Theres convergence in the carbon concentration mechanisms and a bit of debate re oxygenic vs anoxygenic but even there it looks like there's a shared origin or at least co-evolution muddled with horizontal gene transfer, which still isn't de novo convergent evolution. Either way, I absolutely love the content so please keep it coming! Cheers
One thing is for certain: there is no stopping them; the ants will soon be here. And I for one welcome our new insect overlords. I'd like to remind them that as a trusted UA-cam personality, I can be helpful in rounding up others to toil in their underground sugar caves.
Well, this UA-camr was possibly a little hasty earlier he’d like to reaffirm his allegiance to this planet and its human leaders. They may not be perfect but it’s still the best governments we have. For now.
Remember or read a book called communion and you respect for this planets insect kingdom our scientist call a genus I call genius. I really believe a mosquito is as wise Albert Einstein or Wiser for the insect knew to split an atom as a weapon to hurt the natural world is the apitamy if inferior way and that book called communion with as much live as him you will see. The CIA and scientists glue cameras and electronics to steal and betray another sight and embodiment, can you see what else they di they don't want you to believe the do do and hope we don't go the way if the doe doe.
I really loved this documentation! Very carefully edited and extremely informative while also being very entertaining. My new favorite documentary! Thanks a lot for this masterpiece!
Given how destructive humans are, we will go from friendly to enslaving as soon as we have an upper hand, but who knows they could be just as the same or even worse
They are already here! - we are not alone! - there is no question about it - I witnessed a UAP back in feb 2004. Zig zagging side to side, up and down - moving fast and stopping without slowing down, no sound whatsoever, moving at speeds that are beyond belief. I live in Norway and I am convinced what I witnessed was an alien craft over the mountain directly across from my house. The way it moved defied physics. I made a video about it and posted it on my youtube blog channel if anyone is interested in hearing my story.
Alex, huge fan been watching for years and have seen all your videos starting from a realistic representation of the solar system. Last time I commented it was asking for a new video on venus and i like to think my comment wasnt overlooked because you delivered as you always do. Im always excited when i get a notification that you or Astrum Extra posted a new video. Anyways i was wondering if youve seen the netflix show “3 Body Problem” it incorporates aliens, quantum physics, and has a great story to it based on the Wow signal. I wanted to know if you thought maybe “3 Body Problem” was more realistic than alien, avatar, interstellar, or any other movies youve covered. Thanks!
it's great that you do these long videos because I just love this topic. I have no problems with these long documentaries on interesting subjects like this one. so thank you very much for giving us the opportunity to learn more and more.
In addition to the celestial mechanics mentioned as factors that may be requisites for life--a habitable distance from a stable star, within a protective magneto-sphere--we should probably add: * the near-ideal periodicity of orbit and rotation--length of years and days; * our orbital eccentricity, nearly circular, not extremely elliptical; * orbital obliquity--our 24-degree tilt of planetary axis; * plate tectonics, preventing atmospheric or evolutionary stasis; * fractions of elemental carbon, oxygen, phosphorus, nitrogen, iron, sodium, calcium, potassium, zinc, silica, magnesium and, of course, water; * a single, hefty moon, to induce tidal cycles that oxygenate the seas, humidify the air and regularize circulation between thermal and mineral concentrates; * weather that circulates the atmosphere and erodes topography, again defying stasis, distributing isostatic compression and rebound, and correcting derangements of temperature & turbulence toward terrestrial equipoise. Then there are nearly endless contingencies that retrospectively seem necessary for complex intelligence to emerge: * An abiogenic event that birthed a first ancestor of all vital beings, with a double-facing hydrophillic/hydrophobic lipid membrane capable of cell individuation from hostile externalities, and an exchange of nutrients and waste for internal metabolism, and a mode of reproduction that consequently launched an enduring germ-line for every species for the following 4,000,000,000 years, * cell nuclear complexity (the eukaryota), * RNA, DNA or a similar molecule for highly condensed archiving of reproductive information, * random assortment of genes in meiosis, * sexual reassortment of parental alleleic sequences, * photosynthetic potential, * endothermy and oxygen for optimal metabolism and energy expenditure, * motility with jawed skeletal, sufficient circulatory and neuromuscular anatomy for intentional directionality, sensation, perception and prey/predator dynamism, * something like fungal species to recycle environmental nutrients, * a robust dynamic like natural selection for best-adapted phenotypes and their default proliferation constantly refining vigorous genotypes, * omnivory, bipedality & dexterity, and neoteny balanced by mortality & longevity, * consciousness, cognition and sentient volition, an inextinguishable reflex for survival, reciprocal regard of conspecifics, loyalty to kith & devotion to kin, * a number sense, innate geometric form recognition, pulse, tone interval and metric patterns for generating lyrical sounds of music, * concepts of ciphers, zero, triangulation, symmetry and proportion, * capacity for imagined projectile trajectories, navigation of gravity, leverage, rotary motion, inclines, pulleys and cantilevers, * gymnastic tumbling, running, swimming and brachiation, * intellectual inquiry, experimentation, productive skepticism, * valence of logic, access to deduction & induction, intuition & counter-intuition, * a sense of play, creativity, exploration, discovery and invention, * anatomy & social compulsion for syntactical language, noun/verb/object world apprehension, metaphorical schemata, poetic generativity, fictional drama and story-telling, * writing systems for consensus proclamations and extra-somatic archives of civilization, * notions of wonder, truth, beauty, art, initiative, fairness, transgression, cruelty, transcendence, magnanimity and the sublime, * memory and the appreciation and veneration of ancestry, * empathy, love, social ethics, integrity of character, self-sufficiency & cooperation, individuality and culturally defined virtue, * arc of life achievement, shared resources & future anticipation of progeny, legacies and an ancient vestigial impulse to make one's mark on civilization, and leave a better world than the one that greeted us. In other words, anyone who cultivates a cavalier certainty of life on other planets hasn't understood the forbidding threshold of life's requisite circumstances. And I think they have particularly neglected the above requirements whose absence would make improbable a world permitting our own existence, and its web of complex, compound contingencies. That web of fortuities has hosted preposterously wonderful examples of humanity, like: Sappho, Cyrus, Thucydides, Eratosthenes, Pythias, Arminius, Quintillian, Mencius, Viriathus, Lucretius, Tacitus, Hadrian, Zenobia, Hypatia, Boethius, Ibn Rusd, Frederick II, Ibn Sina, Hildegard, Al-Haithm, Alcuin, Casimir, Ibn Battuta, Leonardo, Kepler, Petrarch, Shakespeare, Bruegel & Bruegel, Jahan, Fibonacci, Bartolome, Dossi, Murasaki, Balboa, Rembrandt, Descartes, Bernini, Bellini, Velasquez, Purcell, Bolivar, Rameau, Bach, Levoisier, Kant, Euler, Powhaten, Lafayette, Tecumseh, Pushkin, Hokusai, Geronimo, Dumond, Volta, Montesquieu, Goya, Linnaeus, Ingres, Sacajawea, Tubman, Red Cloud, Crazy Horse, Byron, Lovelace, Mendelssohn, Mendelssohn & Mendelssohn, Saint-Saens, Darwin & Darwin, Borodin, Humboldt & Humboldt, Brahms, Koch, Soule, Ramanujan, Sargent, Pasteur, Dvorak, Husserl, Ravel, Ataturk, Joplin, Modigliani, Lili'uokalani, DuBois, Whitman, Zola, Hubble, Dewey, Cavafy, Bartok, Melville, Vavilov, Sibelius, Curie, Maxwell, Woolf, Ramon Y Cajal, Marti, Sun Yat Sen, Wilde, Keller, Stein, Prokofieff, Bohr, Joyce, Mahler, Turing, Lemaître, Sanger, Bonhoeffer, Katchaturian, Chang, Cassin, Malek, Roosevelt, Anderson, Saroyan, Lorca, Barber, Gandhi, Trilling, Berlin, Ginastera, Boulanger, Tagore, Renoir, Renoir & Renoir, Forster, Akhmatova, Wittgenstein, Luxembourg, Elgar, Gropius, Puccini, Gershwin, Beckstein, Atlee, Brecht, Salk, Perkins, Faulkner, Armstrong, Kollwitz, Saarinen, de Beauvoir, Nabokov, Garbo, Crick, Franklin, Liuzzo, Carson, Vargas Llosa, Bishop, Meir, Biko, Sontag, Henze, Garcia Marquez, Simone, Lessing, Bhutto, Ashrawi, Calder, Alvarez & Alvarez, Folkman, Pamuk, Bischoff, Callas, Chomskey, Gorbachev, Tutu, Goodall, Fairuz, Chatergee, Merkel, Mantel and Ardern. That is the smallest, glancing fraction of all the powerful but humble humans of blistering intelligence and surpassing conviction, historical characters of geared comprehension of the world and deeply plumbed self-knowledge. They typified our profoundly emotional yet stubbornly rational encephalons; an entity of intentional, self-propelled understanding that can emerge only in social obligates who maximize neoteny and the generational accumulation of knowledge, who manage to keep aggression and arrogance less destructive than incurious ignorance, and who insist on empathy over selfishness, justice over rage, equanimity over cruelty and nobility of sapient agency over self-indulgent isolation, to steward the sustained vigor of our garden planet and cherish the fortune of our evolutionary endowment. Those sorts of creatures don't pop up everywhere; in fact, they are probably occupying the one cosmic circumstance they seem least prepared to accept: A lone existence on the distant shores of the only world that ever countenanced animated vitality and reasoned intentionality; moreover they are the only 8,000,000,000 bundles of such wonder that evolution produced in all of spacetime. I say stop tilting at exoplanets and revel in our singular, exuberant, self-determined lives.
I don't know how this one escaped me. I have seen a few of the parts, but not others. As an astrobiologist, I think it's great that you put an easy to digest, entertaining look at the science to life and the ways in which we are working to find the origins and future of life
Given the amount of Space rocks, asteroids and general space junk that Jupiter sucks up with its gravity, is it not possible that over millions of years it will eventually have a rocky core and not just be a gas giant?
It's worth mentioning that there actually a few species of bacteria that do live and reproduce in environments entirely bereft of water. They are the most extreme of the extreme found in natural asphalt, tar pits and heavy oil. Most microbes that live in oil deposits still need tiny amounts of water that's present but their tarpit relatives discovered in California recently live in environments totally bereft of water. They seem to use the hydrocarbons and what oxygen is available locked up in other compounds to produce any of the water they use in their internal chemistry. They also are extremely long lived and slow with some spending their lives on a timescale longer than most plants.
A good additional thing to mention about the Nimitz case is that the location the UFO reappared to 60ish miles away wasnt just a random spot, but the squads previous designated location. They had very clearly intended to head to the point the UFO reappeared
why everyone forgets the K type Orange dwarf stars. longer lived than our sun but more stable than red dwarf stars. + there are more of them than sun-like stars, not as many as M-class stars, but still far more than sun-like stars. the habitable zone is further away than for red dwarf stars and thus tidal locking is not guaranteed. thus they can rotate like the earth on its own axis. and thus they are superior in almost every way to solar-like G-class stars and M stars / red dwarfs.
Thank you very much for this thought-provoking and awe-inspiring video. Too long? I was sad when it ended! You could announce an asteroid was hurtling to Earth to end us all, and I would probably think, "Goodness, isn't his accent lovely!" Oh, please, YES! Do MORE! Thank you 💖💖💖
"They are not building massive structures that might tip us off to their existence", he says, completely oblivious of the fact that megalithic construction has occurred throughout the world, and the best guess of who was involved in that construction has got to be some aspect of the NHI currently interacting with humanity. We've been "tipped".
The first time I have come across ur channel. I found this documentary genuinely fascinating and really informative. Thanks man! Will defo be watching again. First time I've seen the Drake equation be calculated 2. Amazing. I'm definitely on the optimistic side of that!
I feel that when a lifeform is able to create its own environment as we do it no longer is subject to the pressures that have moulded it's evolution. It then would remain static in evolutionary terms and kind of tidally locked until it exhausts all of its naturally based resources.
Thanks for this video. I always wondered a lot of these same questions regarding the habitability and the likelihood of intelligent life evolving on tidally locked planets that orbit a red dwarf.
Whenever I think about this subject, I speculate there’s only 1 intelligent species per galaxy. Even at that, it would mean there’s many in the vastness of the Universe… still doesn’t grant we’ll find any, since galaxies are speeding away from each other. This was a great video to spur one’s thinking about the subject, thanks for the effort.
I think we will look for life that "may be smarter than we are." The wording is key. If we find aliens that are obviously smarter, we will not be interested. We want what seems might be smarter, like apes and elephants. We would be intimidated by any seeming smarter, like creatures of our planet that we study but do not set apart safety for them to ensure their environment.
Solar systems are all moving around. If you aim a radio message towards a star that’s far enough away, you’ll miss by the time the message gets there. Also, the message will probably be weaker the further away the star you’re broadcasting to is. It could be inaudible by the time it gets there.
I really hope you enjoy this supercut! Parts of 12 different episodes have gone into this one, plus a lot of extra content made specifically for this video. I know this is a very long video, so I'm curious to know how you get on with it, so I can gauge whether I should ever do something like this again in the future.
Thanks for watching!
Alex
We are the aliens of this world 😏🫶
Thanks Alex!
Every so called "scientist" that does not see that the universe is a living thing is just a mechanic. His mind can only process the obvious parts of life before his eyes.
Everything is alive. Life does not end at the other side of a cell's membrane. A city is an organism too. There is no isolated system in the universe. It's systems within systems, overlapping each other.
God is life itself. Everything in life is connected. We are part of a greater being. Religions are just different languages, they are an attempt to communicate this insight to other humans. With science getting more and more of the picture (macrocosm, microcosm), and people getting educated about it, it will be easier and easier for everyone to understand it.
For that:☮️, you have to see this:☯️
Everything is made up of pure energy. Particles are vibrations in energy fields (Quantum Field Theory). Matter is an illusion.
Biological humanoid aliens far more advanced than us may already have transitioned into cyborgs or full synthetics 💟🌌☮️
My wife and I are about to celebrate our 55th anniversary. We have set this video as our movie for the night. Thanks for putting this together.
Congrats!
That is the sweetest thing 🥲 congrats and enjoy!
AWW STAY BLESSED ALWAYS AMEEN AMEN 🙏
aww, and here i am about to sign my divorce papers.
Congrats!! I too like to watch material such as this and I hope to find a nice lady to enjoy this with some day 😭
All in good time I suppose.
Hello Alex,
I’m a grandma from Manchester UK and I really enjoy your videos. I think they’re extremely well done and your delivery is perfect for me. You explore and explain things with a direct, clear manner. Plus, I enjoy the topics you share - even in my sixties I still love to learn.
Hello Grandma! Hope you're having a nice day 💛✨
Learning should be a life long pursuit. The older I get the less I realize I know.
I do not understand your reply but I think what you said was important, but did you intend it negatively or positively?@abumohandes4487
I hope you are doing well Grandma ❤️
Gran PLEASE stop hitting the bong, litle luno needs new shoes, you cant keep spending it all on the devils lettuce
*"Temperature can affect size"*
"I WAS IN THE POOL"
🤣
Sure
George?
"You mean like laundry?"
It shrinks? 😮
This has given me nearly 2 weeks of content to fall asleep to.
Everytime I go to bed I resume the video to the point I last remember.
Theres few things more comforting in my life than being able to watch this channel and a few other similar ones most nights.
Same here. Just tucking in and happy that I don't have to search for videos to fall asleep to for a long time.
I listen to these too. So soothing
It's not that bad.
@@stevecooper6515 lol, I don't think OP meant to say it's so bad ' can't stay awake while watching it. At least _I_ didn't mean it that way. It's that we intentionally only watch the video when we're about to sleep, for me because I'm always busy for most of the day and I truly enjoy the content so I just have to squeeze in time to watch it.
Ugh you dont know what insomnia is
Astrum, your voice is so calming that I always try listening to them to go to sleep, the only issue is that the content is so interesting I can’t help but to stay awake so that I can enjoy it in it’s entirety.
By far one of my favorite channels man, please keep them coming.

Going all the way back to the 1970s, I was confident the world could cope. But the past 5 to 10 years in this country have changed my mind completely. We’re deeply awash with masses of people who can’t seem to handle or process much of anything. We seem to live in Gooberville, and there will be no quick way out of it.
GOOBERVILLE.???

Have to agree, there is no unity, there is no empathic ability, there is no self reflection, and behind all of that there is no rationality or critical thinking. The older I get the more the percentage estimate grows in my mind of children in adult bodies.
People have survived concentration camps, tortures, world wars, slavery, and the bubonic plague just to succumb to the knowledge of alien existence... Seriously?
@@kurt7937 This. General look and feel of western society is vastly more degenerate than it was even one hundred years ago. I don't believe in conspiracy, but our use of capitalism and marketing has really affected our values and priorities. I think this will be our undoing as a species, unless something brings about a complete flip in that regard. Unfortunately as Mark Fisher once said "it's easier to imagine the end of the world, than the end of capitalism". Perhaps a reset of society via a natural disaster or mass pandemic will nudge us into a better direction.
Hey Alex, thank you. I hope you see this and know how much you've helped so many. It's neither here nor there what I, or anyone else is going through, or has been through but your contributions have helped countless people get through some seriously tough times and been a wonderful escape from our struggles here on Earth and pointed our eyes toward the skies. Toward things greater than ourselves and anything we could possibly imagine. Much love, bud.
Once I understood the scale of the observable universe I came to a realization that discovering or contacting any potensial extra terrestrials was a slim one. Then I also realized the the scale of time and how small we are in that dimension as well. Even within our own galaxy there doesnt seem to be any reasonable setting for us to make any contact with others if they exist, have existed or will exist. In astronomical timescale, we just came into existence and are likely to be just about to vanish. Lets just make sure to fully appreciate the moment as long as it lasts.
I'm afraid the basis of your analysis is fatally flawed, the evidence suggests we have been "making contact" back and forth for thousands of years, you think the fantastical tales of mythical creatures and Gods was some elaborate mushroom trip? This simply cannot fully account for the way words like Demon were created which in Latin means, "warn away from" you think men formed our entire society around keeping these warnings alive for thousands of years, century after century, for all this time!? Think about the ridiculousness of that, those men saw something that completely altered their perspective on the nature of society itself and enacted a multiple millennial plan to get word to us in the modern age that these creatures brought nothing but pain and suffering down upon them, they poured all their lives work into getting the let out in such a way no one ever thought of before or since! That's too much dedication not to heed their warnings.
It happened, we met them before, it went... Poorly on every occasion. So I wear the mantle of the people who no longer speak with us, who left us only subtle clues, because there's going to be a reveal soon, and Humanity has the right to know if they've been played and we have a moral obligation to pursue restitution of the highest for the atrocities left in their wake!
Of course, this may never bear fruit, but it's gotta be the main reason why they haven't invited us into the Fold yet, Imagine having to explain to hundreds of other societies that you interfered with a developing world and altered their entire societal model because you were so bad at it that thousands of years later they still want a piece of your A$$! We'll likely be boycotted and further oppressed by any such Federations just so they don't have to have their dirty laundry put on display, the moment they set foot on our world, was the day they effectively wiped out our species, we never had a choice because of them, I want justice for my Planet!
at least out of all the comments there is someone who actually gets it . congratulation to you! and as terrifying as it is most likely with all the evidence we have at this time, and knowing how amazing the fact of life becoming from a chemical broth...and the stretch of time we have to be ok with 1: not knowing ,and 2: excepting that more likely then not we are alone!
means that this is just a wonderful moment in time meant to be enjoyed!
They Shadowbanned hypothetical beings from space negative talk about their theoretical motivations, what's that tell ya huh!? I gotta be nice to some mythological being from the stars!? Make that make sense hmm!? You not telling us something!?
100% i really wish people understood the percentages of chance and how much time has passed exclusively to earth. I don’t think our brains really conceive of the number 1 million. Let alone 4 billion years and this planet has to be perfect for 4 billion years to only begin life at the very very tail end of that. Remarkable. It’s certainly not impossible others exist, as we do exist. It is still insanely unlikely we ever make contact. Intelligence isn’t always the most adaptable. Billions of creatures are alive just as we are, yet we are the only ones to get off the rock.
Yeah... Rare earth is one that makes most sense.

Let's presume this to be correct. Then the scary scenario exists that we have to carry the torch of consciousness out into the vast expanse or it will (most likely) die out with a wimper.
More likely “our galaxy”. There will be life elsewhere in the universe but sheer distances mean we can never meet. Not to mention the temporal issue. We are here before or after they were there.
I don't understand why some people think it would be "terrifying" if we learn one day that we are truly alone in the universe.
@joesands8860 Think about the infinite vastness of space. If we are the only intelligent life in all that, that is a horrifying prospect. When we go, space would be completely void of life. Just meaningless, endless nothingness.

If ants could talk I would be quite interested in what they have to say out of pure curiosity
Who wouldn't be if ants of all things could talk
What do you think they'd say?
Ants would say humans are really large and really indecent pests who do not have the decency to watch where they step and are a warlike being who try to annihilate us. Is there any wonder why we sting the hell out of them?
I got really high at work one time and me and my co worker stood staring at an ant hill and we were determining which ones were Foreman and helpers and which one was the main superintendent of the ant hill project. You'd see one bigger ant going around and checking on different groups of ants and that ant would go and talk to another ant and that ant would pass on the information to the helpers. Then, we'd cause a collapse of part of their hill then watch the workers being directed to put their dirt in certain places and developing new tunnels. If you looked really close you could even see tiny blue prints the bigger ant was carrying under it's arms. It was so hilarious we stood there for 30 minutes laughing like crazy.
If ants could talk, they'd be war criminals.
Great Job Alex! You actually made me feel less certain that meeting other intelligent life is unlikely and I appreciate that.

We should learn to get along with each other even if there aren't aliens out there. Being this aggressive as a species is no longer necessary, but we still take aggressive approaches to solving our problems in situations where it would be better not to be.

The scale was originally designed in 1964 by the Russian astrophysicist Nikolai Kardashev (who was looking for signs of extraterrestrial life within cosmic signals). It has 3 base classes, each with an energy disposal level: Type I (10¹⁶W), Type II (10²⁶W), and Type III (10³⁶W). Other astronomers have extended the scale to Type IV (10⁴⁶W) and Type V (the energy available to this kind of civilization would equal that of all energy available in not just our universe, but in all universes and in all time-lines). These additions consider both energy access as well as the amount of knowledge the civilizations have access to.
My favorite thing about that scale is that we aren't even a type 1 civilization so imagine how many other planets never make it past where we are

Note on the lack of a dynamo for a magnetic field:
Tidally locked planets are not without rotation. They do in fact rotate because there would be a night/day cycle based on theplamet's yearly orbit. Tiddal locking is not due to rotation ceasing, but by the rotation matching the orbit around the star. Additionally, due to the close in orbits of a tidally locked planet, its year would be much shorter than our Earth year, potentially only a couple weeks or even a few days.
Would this be enough of a dynamo for some, all be it weaker, magnetic field?
Great explanation. It is one of the most common misconceptions that people have about tidal locking. Like most people think far side of the moon or the misnomer "dark side" of the moon is not at all lit by sun. But that is not true. Moon just rotates at the rate at which it revolvves around Earth.
How would there be a day and night cycle if a planet is tidally locked to a star? One side would be facing the light source all throughout the yearly orbit

I'll quote somebody else "when you walk close to an an anthill, do you stop and try to communicate with the ants!? Do you exchange knowledge and technology with them, or do step on a few and be on your way!" This will most likely be the outcome of discovering aliens, we have this weird thing where we projecting human traits onto non-human organisms, what we consider "aliens" might have a totally different agenda than we could ever imagine...
Brilliant analogy 👏🏻
Would you step on or walk over a dog or a kangaroo or koalas...I think at the very least an ant who has made a nuclear bomb, watches sport and imagines movies and literature will at least be studied as smart humans study ants
The analogy relies on thinking about how a human would behave around ants and calls it the most likely outcome, then dismisses all other outcomes by claiming that we are projecting human traits onto non human organisms.
????
@@Magistrate17 the analogy flew over your head faster than a F15...
How would you know that that's what would happen tho? Saying for sure that that's what would happen is just ignorant and lazy. Ants don't have advanced tech. We do.

Even if the galaxy is bursting with planets full of life, we are still alone and we’ll be alone probably forever. Distances in between these worlds are just too immense….
Luckily there’s still a lot not understood about fundamental physics, and it’s easy to underestimate the possible advances in our future.
Agreed. There doesn't seem to be any viable means of traversing interstellar distances, even in theory. We are therefore essentially isolated, and alone.
yes but if/when we reach 5% the speed of light , that means our (robotic) ships can investigate all planets in the milky way in less then 100 million years while that's an enormous amount of time just realize the milky way is roughly 100 times older.
OP is correct, just like we'll never colonize Mars. The reason we exist is because the Earth is a self sustained ecosystem, without it we eventually die. Not to mention humans are more interested in war, we'll destroy ourselves long before ever exploring another solar system....LONG before.

Hey Alex, at 7:51 you say photosynthesis has evolved dozens of times, but my understanding is that it occurred only once. Theres convergence in the carbon concentration mechanisms and a bit of debate re oxygenic vs anoxygenic but even there it looks like there's a shared origin or at least co-evolution muddled with horizontal gene transfer, which still isn't de novo convergent evolution.

In addition to the celestial mechanics mentioned as factors that may be requisites for life--a habitable distance from a stable star, within a protective magneto-sphere--we should probably add:
* the near-ideal periodicity of orbit and rotation--length of years and days;
* our orbital eccentricity, nearly circular, not extremely elliptical;
* orbital obliquity--our 24-degree tilt of planetary axis;
* plate tectonics, preventing atmospheric or evolutionary stasis;
* fractions of elemental carbon, oxygen, phosphorus, nitrogen, iron, sodium, calcium, potassium, zinc, silica, magnesium and, of course, water;
* a single, hefty moon, to induce tidal cycles that oxygenate the seas, humidify the air and regularize circulation between thermal and mineral concentrates;
* weather that circulates the atmosphere and erodes topography, again defying stasis, distributing isostatic compression and rebound, and correcting derangements of temperature & turbulence toward terrestrial equipoise.
Then there are nearly endless contingencies that retrospectively seem necessary for complex intelligence to emerge:
* An abiogenic event that birthed a first ancestor of all vital beings, with a double-facing hydrophillic/hydrophobic lipid membrane capable of cell individuation from hostile externalities, and an exchange of nutrients and waste for internal metabolism, and a mode of reproduction that consequently launched an enduring germ-line for every species for the following 4,000,000,000 years,
* cell nuclear complexity (the eukaryota),
* RNA, DNA or a similar molecule for highly condensed archiving of reproductive information,
* random assortment of genes in meiosis,
* sexual reassortment of parental alleleic sequences,
* photosynthetic potential,
* endothermy and oxygen for optimal metabolism and energy expenditure,
* motility with jawed skeletal, sufficient circulatory and neuromuscular anatomy for intentional directionality, sensation, perception and prey/predator dynamism,
* something like fungal species to recycle environmental nutrients,
* a robust dynamic like natural selection for best-adapted phenotypes and their default proliferation constantly refining vigorous genotypes,
* omnivory, bipedality & dexterity, and neoteny balanced by mortality & longevity,
* consciousness, cognition and sentient volition,
an inextinguishable reflex for survival, reciprocal regard of conspecifics, loyalty to kith & devotion to kin,
* a number sense, innate geometric form recognition, pulse, tone interval and metric patterns for generating lyrical sounds of music,
* concepts of ciphers, zero, triangulation, symmetry and proportion,
* capacity for imagined projectile trajectories, navigation of gravity, leverage, rotary motion, inclines, pulleys and cantilevers,
* gymnastic tumbling, running, swimming and brachiation,
* intellectual inquiry, experimentation, productive skepticism,
* valence of logic, access to deduction & induction, intuition & counter-intuition,
* a sense of play, creativity, exploration, discovery and invention,
* anatomy & social compulsion for syntactical language, noun/verb/object world apprehension, metaphorical schemata, poetic generativity, fictional drama and story-telling,
* writing systems for consensus proclamations and extra-somatic archives of civilization,
* notions of wonder, truth, beauty, art, initiative, fairness, transgression, cruelty, transcendence, magnanimity and the sublime,
* memory and the appreciation and veneration of ancestry,
* empathy, love, social ethics, integrity of character, self-sufficiency & cooperation, individuality and culturally defined virtue,
* arc of life achievement, shared resources & future anticipation of progeny, legacies and an ancient vestigial impulse to make one's mark on civilization, and leave a better world than the one that greeted us.
In other words, anyone who cultivates a cavalier certainty of life on other planets hasn't understood the forbidding threshold of life's requisite circumstances. And I think they have particularly neglected the above requirements whose absence would make improbable a world permitting our own existence, and its web of complex, compound contingencies. That web of fortuities has hosted preposterously wonderful examples of humanity, like:
Sappho, Cyrus, Thucydides, Eratosthenes, Pythias, Arminius, Quintillian, Mencius, Viriathus, Lucretius, Tacitus, Hadrian, Zenobia, Hypatia, Boethius, Ibn Rusd, Frederick II, Ibn Sina, Hildegard, Al-Haithm, Alcuin, Casimir, Ibn Battuta, Leonardo, Kepler, Petrarch, Shakespeare, Bruegel & Bruegel, Jahan, Fibonacci, Bartolome, Dossi, Murasaki, Balboa, Rembrandt, Descartes, Bernini, Bellini, Velasquez, Purcell, Bolivar, Rameau, Bach, Levoisier, Kant, Euler, Powhaten, Lafayette, Tecumseh, Pushkin, Hokusai, Geronimo, Dumond, Volta, Montesquieu, Goya, Linnaeus, Ingres, Sacajawea, Tubman, Red Cloud, Crazy Horse, Byron, Lovelace, Mendelssohn, Mendelssohn & Mendelssohn, Saint-Saens, Darwin & Darwin, Borodin, Humboldt & Humboldt, Brahms, Koch, Soule, Ramanujan, Sargent, Pasteur, Dvorak, Husserl, Ravel, Ataturk, Joplin, Modigliani, Lili'uokalani, DuBois, Whitman, Zola, Hubble, Dewey, Cavafy, Bartok, Melville, Vavilov, Sibelius, Curie, Maxwell, Woolf, Ramon Y Cajal, Marti, Sun Yat Sen, Wilde, Keller, Stein, Prokofieff, Bohr, Joyce, Mahler, Turing, Lemaître, Sanger, Bonhoeffer, Katchaturian, Chang, Cassin, Malek, Roosevelt, Anderson, Saroyan, Lorca, Barber, Gandhi, Trilling, Berlin, Ginastera, Boulanger, Tagore, Renoir, Renoir & Renoir, Forster, Akhmatova, Wittgenstein, Luxembourg, Elgar, Gropius, Puccini, Gershwin, Beckstein, Atlee, Brecht, Salk, Perkins, Faulkner, Armstrong, Kollwitz, Saarinen, de Beauvoir, Nabokov, Garbo, Crick, Franklin, Liuzzo, Carson, Vargas Llosa, Bishop, Meir, Biko, Sontag, Henze, Garcia Marquez, Simone, Lessing, Bhutto, Ashrawi, Calder, Alvarez & Alvarez, Folkman, Pamuk, Bischoff, Callas, Chomskey, Gorbachev, Tutu, Goodall, Fairuz, Chatergee, Merkel, Mantel and Ardern.
That is the smallest, glancing fraction of all the powerful but humble humans of blistering intelligence and surpassing conviction, historical characters of geared comprehension of the world and deeply plumbed self-knowledge. They typified our profoundly emotional yet stubbornly rational encephalons; an entity of intentional, self-propelled understanding that can emerge only in social obligates who maximize neoteny and the generational accumulation of knowledge, who manage to keep aggression and arrogance less destructive than incurious ignorance, and who insist on empathy over selfishness, justice over rage, equanimity over cruelty and nobility of sapient agency over self-indulgent isolation, to steward the sustained vigor of our garden planet and cherish the fortune of our evolutionary endowment.
Those sorts of creatures don't pop up everywhere; in fact, they are probably occupying the one cosmic circumstance they seem least prepared to accept: A lone existence on the distant shores of the only world that ever countenanced animated vitality and reasoned intentionality; moreover they are the only 8,000,000,000 bundles of such wonder that evolution produced in all of spacetime. I say stop tilting at exoplanets and revel in our singular, exuberant, self-determined lives.
I don't know how this one escaped me. I have seen a few of the parts, but not others. As an astrobiologist, I think it's great that you put an easy to digest, entertaining look at the science to life and the ways in which we are working to find the origins and future of life
Absolutely great doc/analysis of "Aliens" issue. Well balanced, logically structured, without annoying sensationalism. Love it! Will share on X!
Too damn unlucky that Mars is just so slightly uninhabitable. Imagine how nice it would be to have a backup planet right next door when we need it.
Given the amount of Space rocks, asteroids and general space junk that Jupiter sucks up with its gravity, is it not possible that over millions of years it will eventually have a rocky core and not just be a gas giant?
It's worth mentioning that there actually a few species of bacteria that do live and reproduce in environments entirely bereft of water. They are the most extreme of the extreme found in natural asphalt, tar pits and heavy oil. Most microbes that live in oil deposits still need tiny amounts of water that's present but their tarpit relatives discovered in California recently live in environments totally bereft of water. They seem to use the hydrocarbons and what oxygen is available locked up in other compounds to produce any of the water they use in their internal chemistry.
They also are extremely long lived and slow with some spending their lives on a timescale longer than most plants.
As always mind blowing 🤯 thank you ❤
A good additional thing to mention about the Nimitz case is that the location the UFO reappared to 60ish miles away wasnt just a random spot, but the squads previous designated location. They had very clearly intended to head to the point the UFO reappeared
Hard to imagine, we don't even have the capability of making peace with each other much less with another species
why everyone forgets the K type Orange dwarf stars. longer lived than our sun but more stable than red dwarf stars. + there are more of them than sun-like stars, not as many as M-class stars, but still far more than sun-like stars. the habitable zone is further away than for red dwarf stars and thus tidal locking is not guaranteed. thus they can rotate like the earth on its own axis. and thus they are superior in almost every way to solar-like G-class stars and M stars / red dwarfs.

The narrator has a nice soothing voice, very comforting.
"They are not building massive structures that might tip us off to their existence", he says, completely oblivious of the fact that megalithic construction has occurred throughout the world, and the best guess of who was involved in that construction has got to be some aspect of the NHI currently interacting with humanity. We've been "tipped".
The first time I have come across ur channel. I found this documentary genuinely fascinating and really informative. Thanks man! Will defo be watching again. First time I've seen the Drake equation be calculated 2. Amazing. I'm definitely on the optimistic side of that!
Six months after first contact aliens will be the mystery ingredient on a cooking show.
omg a astrum podcast tyvmmm!!
Ooh I’m glad I came by this channel. Wonderful video, very well made!
I feel that when a lifeform is able to create its own environment as we do it no longer is subject to the pressures that have moulded it's evolution. It then would remain static in evolutionary terms and kind of tidally locked until it exhausts all of its naturally based resources.
Thanks for this video.
I always wondered a lot of these same questions regarding the habitability and the likelihood of intelligent life evolving on tidally locked planets that orbit a red dwarf.
Whenever I think about this subject, I speculate there’s only 1 intelligent species per galaxy. Even at that, it would mean there’s many in the vastness of the Universe… still doesn’t grant we’ll find any, since galaxies are speeding away from each other. This was a great video to spur one’s thinking about the subject, thanks for the effort.
Great episode! Thanks for all your diligent and thoughtful work👏👏
Beautiful work, my friend. Inspiring and informational!
Thank you for this amazing, educational and informative documentary.. I had a very enlightening experience watching it.
I think we will look for life that "may be smarter than we are." The wording is key. If we find aliens that are obviously smarter, we will not be interested. We want what seems might be smarter, like apes and elephants. We would be intimidated by any seeming smarter, like creatures of our planet that we study but do not set apart safety for them to ensure their environment.
If humans found alien life it would try to use it, or eat it or fight it. That's what we have always done to all the life all around us already.
Your videos are the best. So informative. Awesome editing
Solar systems are all moving around. If you aim a radio message towards a star that’s far enough away, you’ll miss by the time the message gets there. Also, the message will probably be weaker the further away the star you’re broadcasting to is. It could be inaudible by the time it gets there.
If you want to communicate with other planets. Why haven’t we put an antenna out in space? It will cut down on the distances for transmissions.
