Extraterrestrial Civilizations And Why We Can't Detect Them
HTML-код
- Опубликовано: 28 сен 2024
- In this video, I take a look at the reasons as to why extraterrestrial civilizations currently exist or will eventually exist and then go over the reasons as to why we can't detect traces of extraterrestrial civilizations that currently exist or the traces of ones that existed and went extinct.
(I also try to calculate as to what approximately the number of planets in the observable universe is and connect it to the idea of extraterrestrial civilizations existing)
The majority of the footage in this video was made with Space Engine.

I wonder how far away from earth there actually is someone who thinks about the same topic? What is the actual distance? It probably is ridiculously far away from us and that is kind of sad...
It's not sad, it's beautiful that they're likely to exist either way :)
Technology will get us there one day
Why would you say "probably", did you do any research to come to a probability estimation?
life is probably so common the gas giant orbiting proxima centauri could have moons with microbial life but intelligence is probably at the other corner of the galaxy
@@GlorifiedPig In all the history of the universe there hasn't been any alien civilization that has been able to visit us. Why would humanity be?
@@churrascodupao6410 we don't know that!! What a stupid a comment. I'm not insulting you as a person let's get that straight but the comment is absurd.
I MISSED YOU OMG 😿😿
SAME
No
Great video. I will publish soon a paper suggesting where could the WOW! Signal have come from. I think we should try to find exoplanets around that star.
Hell ya
That stuff is just facinating to me!
The wow signal shot out from uranus
Its from a planet going in front of its suns sum light if I remember correctly
@@carletouk that's not the only signal that shot out from my anus🤦🏼♂️
I truly feel like there is life outside of earth ,considering the size of the universe and the amount of planets we found I cant see earth being the only place with life in this universe.
Technically there already is life outside of earth and no I'm not just talking about the ISS. We contaminated the moon and Mars with earth microbes when we landed probes on them. Yes scientists did thier best to sterilize the equipment but no matter what they were not gonna be able to kill off everything.
@@lightyagami3492 What I meant to say was life that does not come from earth ,Pretty much alien life.
@@Hamzaben710 Well said. I believe that us as a civilization might just not be advanced enough to even detect any alien activity. If there even is any alien activity in our galaxy though...
Maybe in a few hundred or thousand years we will know. I hope so. Or who knows, maybe we will find something within this decade - but even if we do find alien civilizations, we definitely could not reach them, unfortunately...
@@oilersridersbluejays There is a theory that the reason we have not met aliens is simply because the distance between us and them is so great we have not had any contact with them
Are we alone in the universe? Yes we are. So there is no other life out there? Yes,
there is, but they are alone too.
Extra terrestrial life exists out there. There are even species that can travel between stars. The problem is humans aren't actually advanced enough to be noticed. We can't even send a human to the edges of the solar system. It's terrifying but before we reach a stage where we will evolve sufficiently, we'll allow something to wipe us out because of inaction. The human race is divided and always will be. As one race we'd be amazing. But we're simply tribes playing at being grown ups. 😔
"Humans aren't advanced enough to be noticed"
If aliens have the technology to travel between galaxies they have the technology to "notice" us
@Alwyn Ash We simply are not evolved enough, were so so so early in our development. Just 100 years ago, people weren't having these conversations on the internet - that's literally just how new of a civilization we are...
Not necessarily. If another civilization had the technology to see this planet right now, they’d easily tell we are here. Look at how this planet looks on its night side, cities/towns brilliantly glow each part of civilization throughout the planet. I’d highly doubt they’d think that was anything natural.
no stupid, extraterrestrial life would be seeing us million of years in the past and so thus they would have low expectations to even find us if they were to be looking at earth which let me remind you would be looking at it from millions of years in the past and by the time they would go to our solar system the sun would prob be a big red gient most lickely consuming earth
You have to remember if they are a Billion life years away they are seeing our planet the way it looked a Billion years ago.
They might not see lights or cities because they could possibly be beyond that threshold.
Even electricity is new in the grand scheme of things.
I love you channel so much, I hope you’re always making videos 🖤 thank you for all the hard work
The most interesting videos in the observable universe.
Really enjoyed this video Drekser you really put effort in your videos, Well done.
Your English has gotten so smooth man! Great work!
Essentially no accent, I just watched the seeing earth from andromeda video and it’s such a huge difference.
I believe that if a species evolve to become "inteligent" and is wired such as termites, ants or bees, that specie can cross the filter because it can evolve as a single group, avoiding war and focusing in space colonization.
Our current exoplanet detection methods have a bias towards detecting large planets in close orbit to their parent star. Small planets in the habitable zone are more difficult to detect.
Thank God you started uploading again
So relaxing to learn and listen to
Love your videos man. Please keeping knock in them out.
The reason we can’t detect them is is very simple. The universe is 97 billion light years across. The nearest life may be 4 million light years or a hundred million light years away. A message at the speed of light would take 4 million or 100 million years to get there. The universe is so unbelievably huge that we are alone in our isolation, separated by huge spans of time. So that we most likely will never come into contact with another planet like ours over the course of the very short life span of our civilization which probably at best will not last over 10,000 thousand years
I agree this is the most logical solution
In addition to what you said. Messages going out towards said systems millions and billions of light years away, by the time those one-way trips complete, some systems could die via super or hypernovae.
The expectation that life exists elsewhere in the universe comes from the fictional idea that life on Earth emerged spontaneously from nutrient-rich warm ocean water. This science fiction continues to be thought as common knowledge, despite it was never proven experimentally. There is zero scientific proof that life naturally emerges from non-living matter - exactly the same amount as for the belief that life is divinely created by God! Actually the religious proposition has better standing because as spiritual and philosophical account it does not require the exact experimental proof, required for the acceptance of an admittedly scientific theory.
@@lounatanasov4344 we already have two reasonable scientific models that partly explain the origin of life because of abiogenesis. Abiogenesis is the default theory assumed by the overwhelming majority of scientists.
Exactly the problem: the abiogenesis theory was never proven experimentally, which is a required step of the scientific method. A theory which cannot be proven experimentally is merely a speculation. Scientific community's opinion is not substitute for experimental proof.
A gently, sympathetic voice & magnificent documentation & soundtrack!

Holy moly he already uploaded a new video???
upload more frequently my good bro
I think it's possibly as noted on an episode of Star Trek. They're here, they've always been here. We simply/ don't see them because they move faster than an eye can see
Heavily underrated content, keep up the good work man
All these kind of videos are calmful to my mind. They give me a peaceful feeling. :)
, Thanks for the video! As Aaways quality content!
The amount of stans are uncountable
Earth like planets or Moons (if around gas giant) are common. With life like us is rare
You deserve millions of subscribers
Great vid, but there is one point I cannot follow you:
What would be the point of sending out von Neumann probes if they can't report home? At least within the timespan your civilization still exists?
It would be the same as sending out self-replicating drift bottles containing only the message: "I was here once". Some individuals could be inclined to do something like this to create a monument to themselves even if they don't know if ever any kind of creature will see it. But a civilization? Why waste resources to pollute the galactic environment with a self-replicating resource-wasting mechanism? That would only be at least a bit rational if you created real AI and a way to upload your minds into it, making the von Neumann probes your own new bodies.
I don't believe there would be many civilizations sending out von Neumann probes, and if they did, they would probably come into conflict with the very first civilization their probes encounter because that civilization disagrees with the dismantling of the comets and asteroids in their solar systems by replicating machines - and therefore try to shut (or shoot) them down.
My brain starts to hurt thinking about all this stuff.
Human life form is so complex that it's almost hard to believe we came from a single cell organism.
There is something far greater than we know off.
My question is if we built a Saturn 5 with all 1 stage earth orbit? How fast could it go? and could a human survive the trip in vacuum space?
Maybe we don't need to detect them, because they _already detected us._
:)
Clearly there is life, probably many many life forms, out there.
Unfortunately distance stops us finding them.
Great work!
Keep I mind because of gravitational clustering of galaxies, it is likely completely impossible to ever travel between clusters of galaxies, which includes traveling outside our cluster. Unless faster than light travel is possible, the expansion of the universe would likely prevent the possibility of ever finding out if there was life in most of the observable universe due to this phenomenon
great work
For as long as we've been looking, you'd think we'd have seen SOMETHING by now, even if that something was only able to strongly suggest of life elsewhere. What if it turns out, in spite of all odds, that we are the only sentient beings in the universe?
Also, it’s not like we’ve been looking for eons upon eons, we have only started sendjng radio signals into space 124 years ago
Can you upload more?
Why do most of us assume that alien life has evolved into intelligent technological societies? Why do we also assume the potential cultures of intelligent / technological alien life has figured out fusion energy and faster than light travel?I say most alien life right now throught the universe no intelligent life has yet to become organized beyond animal, plant, and fungi life. Life like humanity are unique in the universe for the lifetime of a species. Even if two such species with technology are in the universe at the same time. neither of us would be able to visit let alone communicate with each other.
In the 80s, we actually sent out a message through vibrations saying, “hello”
You mean the golden record
he mentions this around the 6:30 mark.

Wow I never even considered the whole simulation thing. Very interesting
YES! The 👑 is back, keep up the great work!
Do we give any signals to the potential allien neighbors ? if you're on alpha century would you even notice that there is civilization on the Earth?
Your videos are getting longer and better! Ok, extraterrestrial civilisations? We might not be able to identify them because we might not even think they’re alive.
The main question that needs to be asked is if a civilization smarter than humans exist and how likely they will contact us or alternatively as humans overall as much as we admit are far below down the civilization scale and the only way we could hope to survive is to establish contact with aliens even if they end up colonising others we could have a chance to survive among their ranks hopefully compared to dying alone while being unheard from the rest of the universe
As of right now with the war humanity is with wars and old century ways limiting space exploration one of the only hopes we can have is for a alien civilization able to colonize multiple galaxies or planets to approach our planet and even if they colonize us the positives will be access to their technologies and understand to gain control with them or reach a understanding about human flaws and showing the positives of human potential and the drive and will to do anything and imagination of the human mind, if any alien sightings are present or will be present we probably should understand than instead of being fearful like the majority of population is
Sweet. Lovin' it. Subscribed.
Even if such technology does exist for us to reach them and if we're more advanced than them and making contact with them would probably go bad for them.
Yeahhh he is back!
Another theory that were intelligent life probably gets started is around F Type Stars of all main sequence stars i know right. But they say their high luminosity and solar radiation kicks starts much faster than our close in size G Type Star G2V and with a much wider HZ . These F Type Stars they are referring to are F7V- F9V and those are close to GV0-G2V so there might be something to it. And they can reach 6-7 billion years before exhausting there hydrogen fuel. And I can't forget K Type Stars either but only K0V-K3V the larger end.
Ah yes Another video let's go
Yes! A new video! I love your channel so much! I hope you continue to succeed! I’m a big fan! I learned so much by watching your videos! Thank you! 😊
I miss ert!

why did u make the vid private e😡
Love this page
Your videos are awesome
Hey Dreksler, Do you think that if we ever find intelligent extraterrestrial life, it will be like when the Spanish discovered the Aztec and Inca civilizations?
Dark astral a RUclips video on building dome cities on ice planets
Keep in mind even though it was possible for complex life like us to grow on Earth under the right conditions, it can still be possible for other complex life to grow on other planets with their own biological makeup and complexity unique to them. Humans are so limited in their understanding about the universe, that unless mankind one day grow advanced enough to travel off of Earth into other planets way deep in space, everything is just assumption until proven otherwise as far as humans can observe. We still don't know all there is to know about our universe. Maybe on other planets, there are animal-like extraterrestrials just like the many animals here that look unlike anything we have ever seen before. Just not as intelligent.
I was taught in school that there are nine planets in our solar system with Pluto being the last one, but that was some time ago like in 1989 or in 1990.
I clicked this thinking “this is all speculation but I’ll give it a go anyways” and you literally opened by saying this was all speculation. You 1 me 0
Cool
Are every stars have own planet?
No not all stars have planets, if a star has planets then it's a solar system
Humans will slowly spread out across the universe so much that when they encounter an alien civilization, they might think that they are just humans
You mean they won't have eight eyes? I'm serious. Your point is very interesting.
@nickchannel5364 I mean that with so much spreading, isolation, and time, groups will change and evolve. Eventually diverging quite a lot. And after a very long period of time could be unrecognizable as humans.
@@sm1522 you are obviously a genius.
Well done!! 🎉
Another way of saying that the chances of a DNA analog self-assembling at one random bond per second being the same time it would take a tortoise to crawl from one end of the universe to the other and back again.
Can’t really speak on that sd we don’t know how abiogenesis works
Why are you speaking so fast

Or maybe, God created us, and no one else.

Who created Mr God?
Asking who created God is like asking who came up with the idea of light or gravity - we can only observe their presence in the univerese, but we can't put them in a box or follow them home. God is the unknowable source of all there is. Mockery can no more insult God, than it can insult light if you call it mr.Light. It's just a closed minded dismisal of difficult to contemplate ideas which only limits the understanding of the ones doing the mocking.

Billions of planets & stars same numbers as Jeff Bezo’s money
Dark astral how about a RUclips video on how would it be like to stand on trapist planet
He already did that
Where have you been 😭
So many UFO have been seen in space and on earth. Your calculations are pointless.
You state rjat it took such and such time for earth to develop complex life capable of creating civilization, however is civilization the correct name and goal for the creation of a lifeform that has already set course firmly towards self extinction for itself and likely the rest of life here? With the uncontrolled growth of the population since reaching its sustainable number of 1 billion in 1800 its doubling time mathmatically continues to shorten. For instance at my birth in 1954 it was already 2.5 billion, an unsustainable number and now approaching 8 only 66yrs later its clear that with the impending collapse of the oceans fishery not to mention our use of that 3/4 of the planet as a dumpsite for billions of peoples human waste daily and toxic wastes we seem to think of as out of sight out of existance that we've gotten kicked out of paradise for bad behavior unfortunatly taking millions of innocent species with us. Instead of worrying about life on other planets and finding other earthlike planets to destroy shouldnt we have concentrated on taking care of this one to begin with? I take umbrage(sic) with the self bestowed moniker of " smart monkey" as no other species has wrought the amount of destruction to the planet that we have. With just a tad less of our preprogramed software for survival ie: selfishness and greed, we almost could've reached for that banana that the tv show Star Trek so suductivly offered. Damn shame , as from what i know of the situation has doomed us and its too late now to reverse course especially considerimg theres no will to do so. Do any of u ever consider that with some 200 plus coumtries on the planet i believe, that at least 3/4 of them spend significant resources on weaponry for armed forces and that all of this waste of resource and thought put into destruction of each other if funneled into constructive education and research would have yeilded the utopia all dream of at nite while polishing their guns.Damn Shame and who knows if therell be another chance somewhere sometime to reach for the golden ring. Rich/San Jose
Dick C. Head is absolutely right about the dangers of population growth, which by 2050 will see the population increase nearly 10 fold since 1800,a blink of an eye in geologic time. But humans lack the will to tackle this and other problems, problems getting worse with every passing year. If by stopping wondering about whether life exists elsewhere, in the Solar System (apart from Earth of course!) or beyond, that could solve the world’s problems then of course I would have no problem with that at all. But such a simple solution to problems can never or will happen - other, many many other things need to be done as well, changing human nature, which to a large degree has always been aggressive and warlike, being just one.
If alien civilizations are like us, then they too will destroy themselves before too much time has passed. And that reduces by a huge extent any chance that they and us can contact each other.
Also remember the Apollo moon landings were not motivated by science or exploration, but by racing the Russians to see who would land first.
As we all know, the Americans did but it was an empty triumph as things turned out. And if Alan Shepherd ‘s flight in May 1961, only 3 weeks after the flight of Yuri Gagarin, taken place before the Russian’s mission as it could easily have done, or if Werner Von Braun had succeeded in getting Explorer 1, America’s first satellite, launched before Sputnik, then the Apollo landings would almost certainly have never taken place.
The point I am making is that humans would never have undergone space exploration for the sake of exploration, knowledge or science without some other less benign motive being involved.

I love your videos, but it's time to accept that life is SACRED and there is a higher power.

I love your channel, but there are traces of ET, both ancient and current, EVERYWHERE. Open your eyes.
I don’t like the way your new video has a different type of commentary.. it sounds like you are constantly trying to avoid controversy/arguments by clarifying that you’re estimating.
We all missed you a lot tho :)
Hmm what’s so bad about that? I think we could all loosen up on being so certain about things all the time.
@@xuclarockerx he just sounds way less confident now. Speaking As a person who has seen literally all his videos, this one just seems less pleasing and less fun. He sounds almost as if hes scared of being attacked by people for using estimated values and not clarifying it.

Great content as always. Realistic with data to back it up but still leaving room to wonder.
In the movie The Sphere one scientist said, that if we ever meet extrterrestial inteligence, the first feeling would probably be an absolute horror
@@yajanon-yor7304 Erian is right. Look at how life interacts on our own planet. It's easy to figure out.
I think it's a good thing that the distance between possible advanced civilizations is so great, for if it were closer and they routinely came into contact, call me a pessimist, but I have no doubt entire advanced civilizations would be annexed through war and conflict. I suspect Darwinism plays out beyond the stars.
Many earth people have met ets and horror was not necessarily the reigning emotion from what I gather. It depends on the et and the context. Some are not so different. Indeed, I have felt horror meeting certain earth people.
I miss your old, soothing voice,,, awesome video as always. I wish you uploaded more regularly
Finally more from my favorite channel !
I love space
Hi Dreksler Amazing Video 👌😊
Man I remember watching Your videos from way back when and your the reason I learned so much about space. You taught me about planet 9, the Milky Way, the planets, the moons, everything. I remember when you had a very thick accent now you speak perfect English and you sound like a professor. Your videos have inspired so many of us and glad people like you exist and make such amazing content. Keep up the great work. You’ve come along way man. Proud of you :)
i think the first vid i watched was the sedna one abt 3-4 years ago and same here. this guy i think started my interest in space but im not sure lol
When you got into the shit about simulations it blew my mind. Crazy shit
Trully mind blowing video. After it, it's hard to move on to everyday banal activities like going to work or shopping, having all these considerations in mind. Masterwork.
I think without a doubt that we aren't alone, humanity just don't have the means to travel far from home.
yes
There maybe more planets in the solar system than we thought so there actually might be 34 planets
I LIKE YOUR VIDEOS KEEP IT UP
Be more active please we miss you 💔
