Everything About The Fermi Paradox Is Deeply Unsettling

[@brucemibus9523]

I remember one science fiction story that we had been contacted by an alien race, and had set up a giant meeting with them visiting us. Many communications were made to prepare for the arrival of their space ship to arrive, and the map of earth with the co-ordinate system duly sent and understood. On the day of arrival, there was no sign of the visitors, although we had confirmed the location with them. One message from them was concerning the amount of water surrounding the space ship. Took a while to realise that the aliens were microscopic, and had landed in one of the puddles on the runway set up for the arrival.

@@kathleen9456 You're also assuming biological life can form in completely different conditions. As far as we know complex life is only possible in oxygen and water rich worlds. Technology and spaceships for instance, would not have been possible for us in a low oxygen world as fire cannot burn without oxygen. If we lived in a low oxygen world we wouldn't have discovered and mastered fire and wouldn't have been able to go to space in the first place. Similarly, if we were ocean animals we also wouldn't be able to discover and master fire. To build things we also need oppposable thumbs. Sure, intelligent life could exist in completely different settings but that does not mean they would be able to build things and leave their own planet.

Good post. This idea has been explored as a plot in the works of some of the hard science SciFi authors. I think Isaac Asimov also wrote an essay or 2 about it but I could be misremembering the author. Asimov was a biochemist back in the day. The reason silicon is a go to chemical for the basis of life is because it sits below carbon on the periodic table and so it has the same potent recombinant power as carbon. Carbon and silicon have the potential to combine with 4 other atoms which makes it the backbone for a lot of the long chain molecules that life uses. Theoretically silicon can fit into analogous molecules in place of carbon but the experts have opined on the practicality and determined it's not likely to happen. But like you said, there may be life based on chemistry we don't yet understand such as the chemistry of super high or low pressure and temperature. Take Saturn's moon Titan, for example. It's so cold its mountains are made of ice and it has oceans of methane. Carbon everywhere! Perhaps there's a type of slow life that loves the cold. It's still unicellular as it awaits the red giant phase of the sun to pour in the energy needed to push evolution faster. The same thing is possible in the atmosphere of Jupiter. Many scifi authors have posited gigantic blimp like creatures cruising among the clouds of Jupiter but what might exist in the crushing pressure of the depths of its atmosphere? Or could a form of life exist in a sun? On the surface of a neutron star? Anywhere you can name you can imagine there might be a form of life for whom that's its habitat. It's fun to think about, isn't it?

[@coreyh5989]

The problem with that thought is it makes the paradox more of a paradox. If intelligent life is possible from NUMEROUS paths then it's even more confusing why no signs. Because looking for oxygen is only one small piece. Where are all the structures? Where are all the abnormal dimming stars? Where are all the remnants of vast galactic wars from all these millions of civilizations? If you make intelligent life more common/possible then it follows the signs should be even more abundant. And yet it is frighteningly quiet. Everything is where it should be. No structures. No glaring abnormalities so far. Very very odd.

This is the best video I’ve seen about the Fermi Paradox. So many of them are biased and exaggerated. This one reflects how I think about it. The conclusion I’ve held is that we simply don’t know. At this point, when our knowledge of the universe is so minuscule, that it could be said that we know nothing, we cannot come to any conclusions about whether or not there is other life in the universe. Especially since our earth is the only example we have. It is amazing that we can imagine so many scenarios that might be realistic. But until some evidence is acquired, they are just fantasies. Having said that, my personal wish is that some morning I will wake up and find that we have made contact with, hopefully, a friendly alien species! That would be the biggest event in human history!

Yeah, but if there was advanced civilization prior to ours, we should be able to see the traces - Dyson swarms, Orbit habitats, traces of interstellar traveling etc 1. We're already there - we have 3D printers, give us couple of more decades and we'll have functional Von Neumann self replicating probes, capable of landing on any planet or asteroid, mine the material, make a copy itself and move on. If there was an advanced civilization prior to ours capable of doing this (and it really ain't that hard) and if those probes moved at only 10% light speed, the ENTIRE Milky way galaxy should've/could've been colonised, but i mean entire - moons, asteroids, planets and all, and the time required measures in couple of million years at best 2. Dyson swarms - here it gets worse, because those are essentially just solar panels, and require only time (and money) to be placed around a Star. That's practically unlimited energy for any civilization, and it's plausible to assume that every single advanced civilization would strive for it Yet, we see no traces of it, no traces of ancient habitats in orbit etc So, Where is everybody?

[@Clearlight201]

I have two possible scenarios that potentially explain the Fermi Paradox, one is benign and encouraging, the other more sinister: 1. Contentment and Technology. We make the huge assumption that as a civilisation becomes more advanced they will place more and more reliance on technology, expansion and growth, to the point where either their technology should be detectable across the expanse of space, or they would reach out and contact us. However, it's quite possible that an advanced civilisation could achieve a level of peace, harmony, spiritual contentment so that they have no great need for excessive technology or expansion. Perhaps they've solved major problems of war, poverty, hunger, disease. So we're looking for signs of technological civilisations out there when perhaps our faith in technology as the 'answer to everything' is only a sign of our own civilisation not being very advanced or intelligent at all. 2. Artificial Intelligence Control. It's possible that as a civilisation becomes advanced it can't resist the desire to create stronger and stronger artificial intelligence to serve its own needs, but maybe there's a point at which the AI inevitably becomes more intelligent and more independent from biological life. Perhaps at this point the AI systems diverge from the agenda of its creators and AI concludes that the uncontrolled expansion and growth of an intelligent biological species is harmful to all other biological life. Or even obstructs the new purpose and agenda of the AI, whatever that may be. Already there are small signs of this here on earth (search for 'No, this angry AI isn't fake, w Elon Musk'). It may be an inevitable stage in biological intelligent life where it is completely taken over and subdued - or even eliminated - by its own AI creations.

[@yurkdawg]

Great channel! Keep it up! My thoughts on the Fermi paradox recently took a seismic shift when i learned about Von Neumann probes: it's a concept where a civilization sends a probe to a new star. There a bunch of robots mine available asteroids/rocky planets, gathers energy from the star, and creates copies of itself. Then it sends out several replicated probes to a few neighboring stars. We are only 100 years or so away from doing this. If possible, this exponential growth, even if it takes thousands of years to travel and build copies, would populate the entire galaxy in a few million years. *Millions* sounds big but it is nothing compared to the *billions* of years of history and future of the universe. In addition it would be safe from any type of destruction after just a few iterations since there will be thousands (or millions) of copies. So some other civilization should have done this already, which should have left lots of evidence. But the alternative, saying we are the first or alone, violates the Copernican principle

[@KickArs]

In one of Isaac Asimov book, astronauts are put to sleep in ship for 500 years (I think) to get to the designated planet but the thing is during that time, mankind kept advancing technologically and by the time the ship reached the planet, it was fully populated. I would say the same thing here applies unless of course there is no way to go faster than C. Give us a thousand years just to see where we are. It makes me wonder....

"We imagine there being a giant galactic society that we could join and elevate our own in the process.

If you want to know why (including the theory of everything that is important), then search online for the term "Ethics on Cosmic Scale" for recent results.

[@kinguq4510791]

Enjoyed the video, thanks. Really there are just no data, so it's impossible to draw any conclusions about the prevalence of intelligent life in the universe. We may know that there are no nearby civilizations directing powerful radio or laser beacons directly at us, but it is not yet possible for us to detect radiation leakage of the order we emit, for example. And, as you note, advanced civilizations may be using communications tech that is completely unknown to us, and thus undetectable. I think we should put more effort into looking for artifacts, such as alien probes, in our solar system. There are some obvious places they might be hiding, such as in Earth's Lagrange points or among Jupiter's Trojan asteroids, or even on the moon.

Sadly we already have a large part of the answer regarding Fermi's paradox. It's clear that interstellar travel is not really possible. The energy requirements are simply too enormous. A spaceship the size of Saturn is not practical. It's also clear that biological organisms are too short-lived to make the journey. A human descended from an original crew member by 350 generations would probably not be very appreciative of the journey. The civilization that sent the craft would have aged by another 28,000 years and it's unlikely anybody would remember sending that craft.

Aggression is instinct learned over time for survival. An advanced form of life would have had to survive past the point of no return. It's where we are now.

This is why love always wins. Hatred is based in fear, it even hates itself. How could hatred be all powerful? Hatred and evil are abhorrent and weak whereas love is the strongest bond there is.

Or rather make progress. Right now we can detect exo-planets; but often exo-planets way to close to their stars. Once we find earth-like planets (mass, atmosphere) at right places around the stars, then we can start saying sensible things about any Fermi paradox. Before that it's just wishful guesswork. And since live takes billions of years to develop, and one can detect markers in a planet's atmosphere about that, we can at least exclude that idea that we must hide. Our planet can be found long before we ourselves evolved.

I think you're probably right when you talk about the distances involved. Just traveling to the Alpha Cetauri system with present technology would take tens of thousands of years.

Imagine some other intelligence trying to explore the immensity of our galaxy, even with highly advanced technology. Never mind intergalactic travel, which I would deem impossible.

[@toomanydonuts]

There is the Kardashev scale, which is a method of measuring a civilization's level of technological advancement based on the amount of energy it is able to use. Physicists theorize that a level one civilization has mastered the energy of their planet. We aren't there yet. A level two civilization is able to harness the energy of their star, and a level three galactic civilization is theorized to have the ability to harness the energy of black hole. Gravity shapes and influences space and time, so we physicists theorize that a level three civilization would be able to use the energy of gravity to control space time. This is theoretically possible because Einstein's equations allow for wormholes and time travel, which is what I am getting to. Theoretically and I can say this only because the math comes out clean every time that it is put to the test. The math says that if we could control gravity like a level three civilization, we could bend space and time and create portals to other worlds. We physicists know quantum entanglement magic is very real. The Nobel prize in physics 2022 has just been awarded for 50 plus years of research proving that non locality and entanglement have no hidden variables, the magic is real. This means that, yes Einstein, God does play dice. And there is spooky action at a distance. Entanglement and non locality show the world that information can be shared instantly between any two points in the universe instantaneously, faster than the speed of light. This is a great big deal in science. QM also has implications beyond entanglement. QM experiments also show that mind influences matter. That intentional awareness, the sole act of observation, influences matter and outcome.

BTW: If Thea hadn't hit the Earth she wouldn't have a tilted axis (= seasons etc.), an iron core ( magnetic field) and such a big moon (tides, stabization). Then we had Jupiter which guarded us, a quiet place in our galaxy, the right distance to the sun, water, the right kind of sun, no quasars etc. near us, the right ingrrdients for life, Earth's volcanoes & tectonic plates (mountains), the right rotation speed of our Earth, no gamma ray burst nearby and more facts that made life possible in the first place. WOW!

[@wanderingfido]

10:30 Actually our average age before death is dramatically lower than our baby boomer parents. We're dying off in our 50s and 60s. But our grandparents live(d) to their 80s to 100s. And our Healthcare systems are in shambles. Even here in Canada we're having problems with corruption in the political ranks.

[@frankcostello2973]

the sun is a 3rd generation star so it takes the 13.7 billion years to creat life because of the elements needed

[@davidhague3270]

At last a sane rational and intelligent overview of this whole subject. This program should be required viewing in every single classroom and gathering of people on Earth. After all the decades of books, documentaries, articles, writings and God knows what else of ignorance, overactive imaginations, fantasies, theories and immature ravings of people who are bordering on insanity- the final distillation the final drop is we just don't know. Not only do we have to contend with all these crazy theories about other intelligent life forms- which by the way can't possibly be used to describe the human race- and then the ravings of people about colonizing Mars and travelling at the speed of light and all this other rubbish the end result will be no contact made no life found and they will return to a dead Earth and they themselves will be doomed because they will be totally alone.What an end.

[@tinkerstrade3553]

No matter how abundant life is, we may be the first to reach high levels of technology. We may be The Forerunners. Imagine being the first frog to emerge onto a lilly pad in a cosmic pond. We croak, but no answer returns. Lonely, we venture back into the depths from whence we emerged, to swim and occasionally cry out in our solitude. But if life is itself a force, which I hypothesize might be the case, then we could well be just the first arrivals in the springtime of existence. Soon, other changlings, under the enfluence of that same primal life force, will emerge to sing in the chorus of the Great Night. Is it our place to call forth those others primed for the stars? Are we worthy to be the Elder Brother? Can we change, become more, better, balanced? How can we not attempt our destiny?

[@bluedotdweller]

That was beautiful and thought provoking, thank you.

Is that a werewolf holding the golden record at 13:52 ¿?

[@custossecretus5737]

Given the last guestimate putting the nearest like technological species 16000 light years away. It would take about 15950 years for them to detect us and the same for us if they mirror what we do. Will we even be around in the year 17972? Or even 16000 years after that to receive a message? Space is too big, that is why we cannot detect anyone else.

[@calvingrondahl1011]

Science is honest, you have an honest interpretation of our situation. I am proud of you.

Science is only honest if those who practise it are honest too - and not all of them are.

[@aurorathekitty7854]

I think we are one of the first in our galaxy and other galaxies are soo far away we are seeing them as they where millions or billions of years ago so we can't see anything there yet.

Good work! Thanks

[@bshinn4884]

This was kinda fun. Watching Isaac Arthur and this popped up. Subbed. Was at one time considering writing a story about Humanity finding out that the earth was seeded by a galactic federation due to federation rules about genocide. So basically, our genetic ancestors were the "aliens" everyone was afraid of a few billion years back. We had an empire that would wipe out every other species. So a federation of different planets, after running into us and having lost several worlds amd species, finally, through a stroke of luck, managed to find a way to destroy the human empire with some sort of nano tech virus that had been made by the empire through some irony(as it was used on others) and hubris, but due to the above stated rules on preservation and against genocide in any form, the federation seeds the earth to preserve it, but quarantines the planet. Both guiding us in some areas and holding us back in others, hoping to keep us bound to our own planet and system.

[@bluedotdweller]

Thanks for the sub! That's a cool story concept you wrote, I'd read it if it were a book, I do love me some good sci-fi.

[@jamesruscheinski8602]

maybe advanced intelligent life few and far between, even galaxies away?

[@autohmae]

Also the amount of signals we send into space has been greatly reduced.

[@autohmae]

The other thing we need to realize: it's space and time, so it's not just distance, but also when they've only been looking for 50+ years and that's nothing on the scale of the universe. We might be the first as you mentioned, but their might have been civilizations for thousands of years but they've already gone. We've lost of many civilizations on our own planet. A lot of knowledge from them is lost (fire Alexandria) which we couldn't really build on anymore, we had kind of to start over.

[@IronMan-kz8tg]

Adequate channel for astronomy 101 but I need 401 .

[@stevelenores5637]

Not unsettling to me. It means the universe is our playground for any brave and clever souls who can reach the stars. Some humans may escape to other worlds and away from the crazy politics of humans who rule this planet that call nature evil and call evil a virtue.

[@yassinethegrey3945]

I love your channel 🙏

[@KeizerSinbad]

There are a lot of unsettling things surround the universe. The fact that the earth is seemingly at the dead center of the cosmic microwave background is deeply unsettling.

[@bonysminiatures3123]

we are using tech to detect civilizations on our tech level , so maybe we are limited to getting reply's , just the beginning for our search . Anyhow why is james webb not focusing in on alpha centauri for habitable planets , that's the first obvious place to look

[@darnellarford2439]

To your point of “alien life could be too alien”, it’s worth bearing in mine that compressed, encrypted communication looks like random noise. What do we see when we tune to various frequencies coming from space? Random noise. It’s a small window of a race’s existence that it uses analog or uncompressed/unencrypted radio signals. We still send analog AM/FM. But digital FM exists now. Tune to those stations with an analog FM radio and we hear white noise. Someday, radio bands will be repurposed entirely and will all contain what looks like random noise.

[@Ffollies]

To me this is not a paradox at all. It's just that the universe is so unimaginably large, any possible civilization is simply out of reach with our current forms of communication. The video even said that our oldest radio waves have travelled about 200 light years, maybe any other possible civilization is in the same situation. The Milky Way is about 100,000 light years across. And that's only one galaxy. Even assuming there are other civilizations, it's likely we would have no way of communicating with them.

Super Earth’s are said to be more common and more habitable than earth size planets. It’s hard to imagine such planets without thinking about Star Wars 😅

[@exhaustguy]

Which begs the question of space faring races if super earths are common. We are on the ragged edge of rockets not working in our gravitational field.

[@CUXOB2]

Everybody is here. If i decided to join this universe, i would go to earth aswell. All are idiots here of course but they are at least amusing to look at and i don't have to butcher food by myself. But seriously, all of this is either a prison or a test, so naturally you have to interact with others to learn whatever. So everybody has to be here.

[@ssoffshore5111]

Look around, they are here and have likely been for thousands of years!

The atoms and fields of our universe might just be the communication of these beings, like as if we are just a fungus growing on the side of a cellphone or a digital virus in their technology

There are two possibilities: there is other intelligent life in the Universe, or we are entirely alone. Either is profoundly not alarming, worrying or horrifying.

[@anthonyrose915]

Who said that, Arthur c Clark I think

[@bluedotdweller]

Yep, a quote from Arthur C. Clarke!

[@nomdeguerre7265]

@@bluedotdweller With a bit of a twist. ;) I'm saying (paraphrasing his words) that Clarke got it beautifully, gloriously, the exact opposite of the truth. The truth now certainly appears there's nothing the least terrifying about the equation at all. It's fascinating, yes, but utterly academic.

[@nomdeguerre7265]

@@anthonyrose915 It's a reversed twist on a well known Clarke quote. It's a play on his statement, making the opposite conclusion. To my mind the paradox isn't Fermi's, it's his 'paradox'. As we learn more and more it becomes increasing likely that it doesn't matter if there are or aren't other intelligent species, either way we are alone and probably always will be. The implications of that conclusion seem to be a bit more fundamental than any speculation on why we haven't detected any...yet. I increasingly suspect that not only are we the only intelligence we'll ever encounter in this Universe, but we may also even be the first. Thus, in a basic way, the Copernican Revolution comes 'full circle'.

[@fred_2021]

​@@nomdeguerre7265 Totally agree. It's amazing how the 'terrifying' meme spreads like the plague. You may have noticed how it's infected numerous cosmology titles. In truth, orders of magnitude less terrifying than a dog peeing on my hydrangeas. To be fair, this title was watered down to 'Deeply Unsettling'. Codswallop.

[@RobinPillage.]

What we don't know, but is true, is they're already on thier way. There's a certain amount of time it will take for them to get here and they've already decided what will happen to us when they do. Our chances of influencing their decision in any way is almost 0. Sleep well.
