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.

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.

@CriminalonCrime

Ай бұрын

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!

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.

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.

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.

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.

There is one thought I rarely stumble upon when it comes to all those considerations about Types of Civilizations or possible Filters etc. which is that all the scaling is based on our current incomplete understanding of Everything.

True that red dwarfs provide "our" problems for life, but one of the constituents for creating life is "distillation" occurring . This would be something that is super far beyond what could happen around a red dwarf, along with the constant of "time". This process over time, that includes a tidal lock is even more pronounced. Also, heat can be generated in a planet specifically from gravity forces internally, which gives these aspects over time better odds at life being created and sustaining. We also have a negative bias here on earth, because when one type of life begins, it may destruct all other promise of a different start to a different type of life. We do know so little. Gr8! Peace ☮💜

Should’ve mentioned the sci fi concept of “Prime Noninterference Directive”. Good old Star Trek explored this concept back in the 60’s. If aliens ever showed up in Earth orbit, or even just transmitted radio/laser/neutrino/whatever signals to us, the chill down my spine such an event would cause would come from my question, “Don’t these guys have a Prime Directive? And if not, WHY not ?” You could get into speculation that they just aren’t as stupid and childishly warlike as us so they don’t have a clue, but then you could ask, “Just how long have they been traveling around the universe? How long can you have warp drive and not have learned a little caution ? And that’s what makes my neck hairs stand up ; maybe they just don’t care.

Awesome commentary, extremely thought provoking Thank you.

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.

You guys are the best! Very informative videos

"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".

This was an excellent episode! Thank you! 🌹🤙🏼

omg a astrum podcast tyvmmm!!

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 💖💖💖

I love that you added “sentient rock monsters”!

That's one of the best videos I've ever seen on KZread. 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

Last night my night sky was immensely enjoyable. I could perceive at least a hundred stars, plus the ISS, & a couple planets, for sure one 😊. I love the outer space realm. I wonder if people on the ISS consider their sleeping positions comfortable 🤔. Thanks for the upload 🙂😊

Very well put together and very, very informative...

Absolutely great doc/analysis of "Aliens" issue. Well balanced, logically structured, without annoying sensationalism. Love it! Will share on X!

Awesomely put together ❤️

Thanks for putting in this hard work Alex, great video

Well done for including the Nimitz encounter

This was absolutely amazing.

Alex...your voice and your delivery: Mesmerizing!!

The monkey that was holding onto it's child's tail to keep it from running off. I approve.

I would just like to point out that even if we are alone, eventually other intelligent life forms will evolve on earth if we are around long enough. Some have argued, for example, that certain primates are currently in their stone age. I'm inclined to agree. We have discovered in recent years that many animals are far more intelligent than previously thought. A lack of opposable fingers for fine motor control could be the only reason we don't see similar species to our own in technological advances. Maybe because of that there aren't other species as intelligent, but there could well be a species on earth capable of communicating on our level or close. There already is depending on how you define communication on our level.

How about NON-verbal communication? 🤔. 🤭.🤫. 🤗

Holy cow, this is really well done.

This is one of the best videos ever uploaded to KZread.

First time watching your videos. Keep up the good work.
