- 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.
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 MISSED YOU OMG 😿😿
SAME
No
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 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.
@Adoragun 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
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.
Damn i subscribed to you at 10k, you are growing everyday. You deserve it.
Great content as always. Realistic with data to back it up but still leaving room to wonder.
I love you channel so much, I hope you’re always making videos 🖤 thank you for all the hard work
Finally more from my favorite channel !
I miss your old, soothing voice,,, awesome video as always. I wish you uploaded more regularly
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.
The most interesting videos in the observable universe.
Thank God you started uploading again
Love your videos man. Please keeping knock in them out.
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
Really enjoyed this video Drekser you really put effort in your videos, Well done.
Your back and I am happy :D
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.
Pls never stop!!! You are my favorite
, Thanks for the video! As Aaways quality content!
great work
Hi Dreksler Amazing Video 👌😊
Great work!
You deserve millions of subscribers
Finally, you are back! 🙏🏻
A gently, sympathetic voice & magnificent documentation & soundtrack!
☝🏻✨🌍🌟🌏🌠🌛🤩
Fascinating episode. Man may not be able to invent lightvspeed travel, but the AI man creates could; possibly.
I believe AI is the next phase of evolution. Robotics will replace biological life. It’s more sustainable, doesn’t rely on atmosphere or temperature, and can live indefinitely.
So we’re done? We don’t get to see the universe, they do
I LIKE YOUR VIDEOS KEEP IT UP
Youre back again nice is there any way to contact you?
Sweet. Lovin' it. Subscribed.
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.
So relaxing to learn and listen to
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 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.
Yeahhh he is back!
upload more frequently my good bro
The king of the cosmos is back
Holy moly he already uploaded a new video???
Nice to hear from you again!!!
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?
Can you upload more?
I love space
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.
The belief that life emerged 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.
I've missed you so much 😭
When you got into the shit about simulations it blew my mind. Crazy shit
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.

@@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.
I really love your way of thinking about this. Everywhere on CZcams or Internet I see people thinking about this problem closed in a box with the importance on Fermi Paradox, or the number of potential intelligent civilizations in our observable universe, but the thing is, we dont know how really big our universe is, we dont know what created our universe and why, every explanation is just a fancy solution made up by scientists and believed automatically by everyone, but we really dont know the real answers to these things. And thats a thing I dont see anyone admitting. In my opinion, it is certain, that there are many intelligent civilizations, but it is also obvious that the ones that didnt destroy themselves or something didnt destroy them, could have very different way of thinking and maybe the “concurring space” thing is just a human desire becuase we are still such a young spieces. The way I look at this is that humanity thinks how advanced it is and how modern of civilization we are, but 200 years ago there were people riding on horses and battling with swords. We are not advanced, we are in our early puberty and you can see it in every corner of this society. Okay im going to stop preaching and im sorry if this sounds stupid to you, but it is just my opinion and the way i see things. Yes. Ofcourse there are aliens. And no, we may never contact them in any way. And thats okay.
200,000 years ago people riding on horses and battling with swords and shield??? Nah brah I think your math wrong bruh I think you ment 2000 years ago not 200,000
Reminded me of Galileo with this. A very interesting way to think. As he once said: 'In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual"
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
Idk but I like your accent it really fits the type of videos your making! Hope it didn't sound weird lol
Love this page
My explanation is that space travel may be harder than we think so developing technologies which we assume are coming are not coming in order we think of
yes
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.
The amount of stans are uncountable
I think without a doubt that we aren't alone, humanity just don't have the means to travel far from home.
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
There maybe more planets in the solar system than we thought so there actually might be 34 planets
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?
Does anyone know at what speed space is expanding?
Earth like planets or Moons (if around gas giant) are common. With life like us is rare
I love this channel
Maybe we don't need to detect them, because they _already detected us._
:)
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.
I like the way this author thinks. The number scenario as evidence that there is more intelligent civilizations out there is also evidence of how far and dispersed we are to ever communicate with any of them or even believe that UFO's are the aliens we think of.
YES! The 👑 is back, keep up the great work!
Be more active please we miss you 💔
kind of ironic how he is talking about how superb simulations might stop a civilization from exploring the universe while footage from space engine which is a superb simulation plays in the background lol
why did u make the vid private e😡
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
Clearly there is life, probably many many life forms, out there.
Unfortunately distance stops us finding them.
Wow I never even considered the whole simulation thing. Very interesting
Make more videos weekly wise
Missed you
Maybe Kepler 452b have an alien in their planets now.
Cosmos is a giant shooting gallery. So many ways for life to get “ended” before it even begins, let alone before it becomes intelligent.
Microbial life is probably relatively common
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 think advanced civilization are very rare and on the other hand it's very hard to do interstellar travel because of the huge distances between stars and hostie environment of the interstellar medium which is even more hostile then space in a stars protective magnetosphere. And maybe a lot do indeed destroy themselves or they do not develop advanced technology needed for space travel. However there are possibilities an advanced civilization did visit Earth about 6000 years ago and this has resulted in the large religions.
I miss ert!
Can you do what if murcery was the moon of Earth
Clever
Anyone else think the first few music notes at the beginning sound like a Beck song?
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.
I do wonder if there is life out there or we are alone
Hola Dreksler 😁
By posing the question "whyyy we can't detect them?" shows how ignorant one can be. It's like filling a tablespoon with ocean water and doubting sharks exist because there is no shark in it. Everything is too vast for us, for a civilization which hasn't even reached level 1 in the Kardashev scale. Will continue to be too vast for us even in millions of years. So if we keep "failling" in detect intelligent life out there is simply because maybe there is still no shark in our ship (not a tablespoon anymore) amid all the oceans...
aren’t we about a 0.65?
Giga Olive 0.73
@@scherebeatle Ah better lmao
This comment ! We think we’re so advanced, we are no where close !
👌👌👌👌👌👌👌
My guess is because when we look at the planets that may have later developed advanced civilizations, we are seeing them way back in the oast, before they could have developed those civilizations.
Your videos are awesome
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
I think there may be plenty of earth like planets out there but without a decent enough sized moon to stabilise them life could struggle our key is our moon.
I personally believe that the only way for us to get here to there is to die. I mean when we die we reincarnate randomly be it still here on earth, through time or through other planets or even other universes.
All these kind of videos are calmful to my mind. They give me a peaceful feeling. :)
Heavily underrated content, keep up the good work man
I heard there's at least 7 at bare minimum planets like Earth in universe
In universe? 7? There’s most likely quadrillions of them
@@dosomestuff1949 with beings who have tech
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.
The sad part is that there may already be extinct alien civilizations....
Cool
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.
