Life has existed on one planet for about 4 billion years, for all we know. But it might have started right after the Big Bang, when the universe was much stranger and more fantastic than today. A universe that might have allowed life to develop absolutely anywhere. The cosmos might be full of the seeds of life, sleeping in a dead desert, waiting for a few drops of rain to explosively bloom and grow. Tiny and not so tiny aliens might be everywhere.

Hi

Can we just all appreciate the quality of these videos, they never fail to amaze me! I’d never miss a Kurzgesagt Upload!
Ur a legend b
Ok.
Nice
Mad lad
HOLY FUCK HE DID IT
As someone who is studying for a PhD in medical genetics, I am simply amazed by this video. Even though evolutionary biology is not my field, my mind was blown by the idea of the universe being warm enough to support life everywhere for millions of years, in the past.
Bring on all the anti-science religious people! This should be good.
Okay but imagine if there was a single civilization as intelligent as we are alive during those first few million years
Would they know that in a few million years their world would be completely chilled because they are in the middle of space, not orbiting any star?
Would they be able to figure out how early they are in the universe?
With 10³⁰ planets I will bet that it did happen at least once during that time
@@Litkeen man.
@@Litkeen Ok, now I want someone to write a sci-fi story with this idea.
@@Litkeen hmm, I think it's unlikely that complex life, as ourselves, would exist so early on in the universe.
This is the first time the alien-seed-theory actually seemed based in logic and science and wasn't just an 'I dunno' cop-out! Thank so much for explaining it so well
I agree, and it really seems like the theory makes sense. But just like everything else, just because it is self-consistent doesn't mean it is actually valid, regardless of how much we may enjoy the idea of it. While it may appear that life is older than Earth, the theories may be a mad dash for an excuse that Earth is not special to justify the wrong doing by so many corporations to, as far we know, the only life that exists in the entire universe. It matters that we don't know what's out there, but at the same time it doesn't because the 'bad guys' can use these kinds of theories to justify whatever they want.
@@CoffeeKillersClubbit of a stretch to think people doing bad things need to go to such lengths just to have another excuse for doing bad things. There's always an excuse. Doesn't matter what our scientific understanding is or ever will be. People will take anything to justify their actions, good or bad.
If the first genomes were alien in origin... then it's another chicken-and-egg paradox. Which one came first, the alien genome or whatever it was that the genome needs to make life and more of itself?
@@user-li1tb3od8lThe primordial universe was so dense and hot that the first genomes and/or proteins may have assembled by chance on asteroids or planets. The argument is that the first genomes were simple enough to have formed by chance, allowing for primordial extremely simple life forms to exist.
@@jovazquez6102the primordial universe did not have a high enough metallicity to form planets or asteroids, and probably not life either
As a professional plumber of 15 years, I am absolutely astounded by this video. To think that the microbes in toilets and pipes could have originated not in our colons, or even on earth, is nothing short of incredible. Thank you for introducing me to these fascinating concepts
It is incredible. So is kurzgesagt now that it's mostly b&m gates foundation globalist propaganda. I did enjoy this one though.
You would think a plumber would be used to the thought of aliens... (Ben10 joke)
Another plumber here, thinking the same thing :)
yes they may have come from Uranus
@@us89na😭
When I was at university, I went to a talk from a scientist working on the (then proposed, now funded) Titan Dragonfly probe mission. One of her answers from the q&a at the end always stuck with me:
Someone had asked her what kind of guidance systems The landing stage would have to avoid obstacles on the ground. She said they would use existing ground maps and on-board radar to detect large obstacles like boulders and chasms. Smaller obstacles, like trees, would be a lot more difficult to detect and dodge -- "but if we land in a tree," she said, "we win."
"damnit, our probe is stuck in a damned tree, and it looks like something is chewing on it as well! Guess we will never know if life exists on that planet!"
That's such an awesome answer
Took me a second to relise why he Said we win
@@raffibagus3035 that is because we find life
>:D
Even after all these years of watching Kurzgesagt, I still can't believe these amazing little documentaries are completely free for everyone to watch. Everyone really should watch them too.

@@Thsovahbowgpwbjajfjwjfeifirjfj not just he but the whole crew.
One of the things I love about Kurzgesagt. All of their masterpiece videos are free for all to watch instead of putting them behind paywells like Patreon or whatever
there is records on where they get their funding. Some of it reaches the political realm.
Kurzgesagt has the 2 sides, the "Look the amazing ways life could actually have started" and the "An alien species has shot a laser to our planet and we dont know till we all die"
Whatever their mood are on each video, the quality is galactic and the fact they do it for us all for FREE makes this deserve all our attention 🗿👌👏👏👏
Hey now, careful throwing that F word around like that
Don't forget "Look at this ant"
Damn, the way you displayed the early universe seems so cozy and colourful. Skies would've been so beautiful with all these galaxies nearby, neabulae etc. Yes, it would be very hostile as well to us, but beautiful as well. Another amazing video Kurzgesagt! You never fail to amaze me!
Unfortunately I don't think that's a very accurate image of the early universe. Galaxies would be very rare back then and the universe would have a glow to it from all the heat still, so nights would not really exist and so seeing anything in the sky would be unlikely. But it is fun/sad to thing about what craziness could be seen in the night skies in the past when stuff was a lot closer to each other.
The idea of primodial microbiotic life soaring through space on comic dust is so terrifying yet so inexplicably amazing
For me it is beautiful and poetic. It is the universe's way of bringing life to all its corners and experimenting with itself.
@@vicentelira4468I agree, its hard to articulate that sense of existential beauty into words
뚜비뚜바
its like cosmic pollen @@vicentelira4468
@@vicentelira4468 yes nothing about it is terrifying.
The perception that it is terrifying is only due to the film and fiction influence on people's perception of alien life.
From a scientist perspective it is simply beautiful, inexplicably fascinating and it evokes so many questions and wonders.
I am actually mindblown by this idea that life could have formed so early, and essentially 'be everywhere'. It would imply even a teeming universe could have life essentially from the same origin, which I think is truly fascinating
What is the Universe? Nothing exists outside of YOUR experience of it. The universe is you. Consciousness is the natural property of existence, it has no beginning or end. You live in a dimensionless space and a timeless now, and there is only one of thing, the only thing that exists is existence.
@@rangarolls6018 What solipsist woo-woo are you peddling here?
@@rangarolls6018I'm sure all that sounds profound in your head, but it's really just a meaningless word salad.
Yeah
It's a beautiful idea. The resilience of life on earth and it's "miracles" walking around is beautiful as it is; but i find the idea of life surviving even space, even more beautiful.
If i had to describe it, it's like admiration for something that just refuses to die; it's admiration for something that fights so, so hard against entropy, wich in turn, starts to look like a villain whose only goal is destruction, even when it really is no more than a physical concept.
If this idea was proven true, it would give a whole different meaning to "life finds a way". That's truly fascinating; life is just, beautiful.
I haven't been in a great spot financially lately, so I've been keeping personal, unnecessary purchases to basically zero.
I think this year's calendar will be the first guilt-free purchase I've made for myself in the last half year. The entire collection is gorgeous, and I've been a fan of Kurzgesagt for about 8 years now. I bought their first calendar and have been wanting to buy another one since then, but I kept forgetting until it was too late; I'm really excited for this year's =)
same! I dunno why I haven't but this year is gonna be my first calendar purchase - Love Kurtzgesagt...
Relatable! A long term Kurtzgesagt fan with consistent financial issues here too, never buying anything unnecessary. I would still love to decorate my place. And I absolutely love the calendar and some other stuff like posters I've seen in the videos. I haven't even dared to open Kurtzgesagt merch store, because there would be so much stuff I want! But I definitely know what to ask my family or friends for a Christmas present this year ;) Or if I reach some sort of financial stability, this merch stuff will be early on my shopping list. :)
my parents have gotten me this calendar every year for Christmas for five years now. I’ve been following this channel since your first video on black holes and how to destroy the universe. I’m so happy to be part of this community, and so proud of how far this channel has come. 😊❤
I can’t explain precisely why, but this video felt extremely magical to watch. I don’t know if it was the story of the idea the whole universe could’ve been alive at one point (and maybe still is), the idea that every potential alien civilisation out there has the same roots, or maybe the stunning soundtrack. Great job Kurzgesagt because I really really like this video.
It's because of that good old indica ;)
This. The possibility that all life in the universe might have the same roots, and that there could be millions of worlds with some kind of life is awe inspiring.
I liked my own comment and yes
@nepaliens6479 you may of found it surreal because it has deep ties to our evolutionary origins. a key example of this bioevolutionary primordial starting block is mushrooms. Their networks make up 60% of earths total biomass, all higher cognitive creatures are extensions of fungal networks and their spores are so electron dense they can survive space radiation. Allowing them to float planet to planet.
The interesting thing is they have symbiotic relationships with higher cognitive beings on planets it has permeated. And can access all previous chained worlds in the form of a trip to provide heavily distilled wisdom. Which is why they were partially seen as gods by old religions. Something to ponder.
the mystical backround sound majority helps out with that
It’s such a crazy yet simple concept I’m actually blown away I never thought of it. The universe at one point was really hot and cooled to where it’s at now. Not sure why I never considered the fact that for a period of time the entire universe felt like going outside on planet earth temperature wise. Guess you’re so often reminded of how hostile the universe is that the idea of it being a comfortable temperature is immediately discarded. At least for me anyway
It is quite fascinating to imagine isn't it! Although it is important to note that it was a pretty short length of time on cosmic scales. First molecules formed after ~100,000 years when the universe had cooled to a chilly 4000° K. Then, somewhere between 10-17 million years after the big bang the universe would've been cooling from 100° C to 0° C which is when this early universe habitable period would've been conceivable. ~7 million years is kinda short for the emergence of life potentially, especially because there likely were few (if any) dense concentrations of matter like a planet yet, but maybe it's enough to make for some extremely primordial life!
@@treyshafferThe most important part for me when looking at this theory is not the amount of time, but the amount of source space that qualified for life. Considering most scientists think the origin of life is a monkey with a typewriter kind of situation, considering that for 7 million years there was a nigh-infinite legion of monkeys makes the whole thing a lot more plausible.
@@treyshafferShort timespan perhaps, but on the other hand the universe is inconceivably large, possibly infinite. So if *all* of it was like a warm summer day it seems that almost anything could happen.
Also interesting the universe was much smaller with the same amount of matter so it was very compact
Meaning the entire Universe would of had an Atmosphere . Imagine going to space without the need for a space suit
I am wondering, maybe because the speed in which the universe cooled down or something else prevented any complex life forms from taking shape or perhaps those creatures died before they could do anything? Seems a bit odd how we are alone. Unless there is truly no possible way to travel faster than light.@@treyshaffer
That's an incredibly beautiful hypothesis. I always felt it was so amazing to look at all life on earth being relatives to each other since we all share common ancestors.
Now, the solution to the life paradox presented here would imply that there are family members of ours out there, in space, possibly all across the universe, as we all origin from the same life seed that first enabled dead molecules to reproduce and spawn the first metabolism.
Since when the whole universe had habitable conditions, there might have been multiple different original seeds, leading to what we could call different dynasties of life, all of which span across large portions of the universe.
I would say, you can't make it up, except some did, haha.
These animations are brilliant. These common simple ideas would have been known to most anyone with an interest in science and reading books decades ago and I was worried that as we continually dumb down, read less and lose interest in anything that isn't digitally done for us younger generations would not be as thoughtful about these topics (or anything really) as generations before them, but with brilliant animation like this sparking interest in bigger topic the following generations still have a pretty good chance.
the idea of the universe being warm enough to support life in the past really blew my mind and I love it
And now only us remain
humankind aka the cockroaches of the universe :P@@soulin11
And yet it makes perfect sense when you think about it: if the Universe went from "very hot" to "very cold", it must have gone through "just good".
It's the first time I hear about the concept of the Goldilocks universe. It absolutely fascinates me. This video (both the visuals and the narrative) is one of the most beautiful works you've made so far.
The fact that content of such astounding quality is available for everyone for free still keeps amazing me. Your project is awesome (it has always been), and contrary to my belief that it could not be done any better, you manage to top yourselves every single time. I can't thank you guys enough for this content, keep it up!!
The peer-review note on one of the main source-papers for this video:
"In this contribution, the author attempts to characterize the functional form of the relationship between the sizes of the functional genome of organisms and their appearance in the fossil record. Using five data points (prokaryotes, eukaryotes, worms, fish, and mammals), the author deduces an exponential increase in functional size with time. He then uses this functional relationship to hypothesize an origin of life that exceeds the age of the Earth by a factor of two. From this he concludes that the origin of life cannot have taken place on Earth, but points towards hypotheses of the panspermia type.
This paper is an example of how not to analyze data."
I recommend checking out their Fermi Paradox videos if your interested in this kind of stuff
First time for me too, which is unusual. I'd really tired of the channel because of all the endless overviews, so I hope this is the start of a trend of giving viewers more credit.
It's not a new concept but it certainly is good. The thought of globs of water in space instead of comets has been such a crazy concept to me.
Another fascinating era of life will be trillions of years from now when red dwarves turn into blue dwarves. they get hotter and will push their habitable zones outward, warming more distant planets. Being the most common of the stars this will mean an insane amount of planets will thaw out and life will have its last, and possibly longest, golden age. There are currently no blue dwarves in the universe because the universe is far to young being in the billions of years old not trillions.
@@elfanarion Well said, this is stepping into the realm of fantasy more than science. Even so, I am glad this video has interested many people in these fun and thought provoking topics. I must say that Kurzgesagt's videos about the medical field are much more credible and well written than their scientific videos.
One of my absolute favourite videos ever!
I just rewatched it, and... WOW!
This video takes you on a journey, explaining everything you need to know a an awesome, precise yet simple way, building of block after another until you can make the most astonishing, well reasoned conclusions!

I am a genetics scientist, and I love your videos - here are my notes regarding it.
The evolutionary clock is a tool that should be used with caution. Typically, evolutionary clocks are designed to detect discrete changes in evolution when coupled with heuristic systems and advanced AI's and programs to approximate (essentially, to periods within a million years) when species diverge. However, when we roll it back, this type of data becomes untenable and stochastic the further and further we push it. Also, size of DNA does not confer complexity - for example, Corn has a comparable size and is extremely complex, and the "size of functional genome" is a misleading term, because genomes carry innumerable functions that exist in benign or seemingly "empty" sections of genetic code. For example, the "function" of color changes in maize kernels is no where to be found when sequencing their genetic code, but a function of their code has huge sections of DNA sequences morphing around - constantly changing position of certain sequences which changes the organism itself, in real time modifying the output of pigment (changing some kernels to black, polka dot, etc). These are called "transposons" and play a huge roll in diversity and function in both corn and humans alike - so much so, that we have to say that they are apart of a "transposome" - like genes are apart of a "genome". Elements of the genetic code like this are inextricably entwined with essentially all life, and therefore size of genomes (in itself) rarely denotes or confers complexity (e.g. Corn is 1/3 as large as humans, but we seem vastly more than 3x as complex than an ear of corn, right?). Thus even if we deny the existence of elements like transposons as being "nonfunctional" and forget that these nonfunctional sections of genetic code harbor huge "game changers" regarding function on both micro and macro molecular scales, and just look at size itself, we see that this is rarely a dimension that can be relied upon when determining complexity and therefore the pathway that evolution has taken to reach it. Although we would love to be able to use molecular clocks in this way, for instance, we could take it a step further. If we could iron out the kinks in genetic data, we could in theory use these clocks to reverse engineer down to pinpoints in a temporal landscape - as in: "On what date and time in history did human beings diverge from the neanderthals?" - do a bit of mathematics and genetics legwork with the help of our best ai models- and begin to synthesize prehistoric (and pre-human) events. We are already able to do this, but the degree of precision is lackluster (millions of years of deviation) and already cloudy and unreliable due to the presence of things like transposons.
Please keep in mind, this is not a request for Kurzgesagt to recant (or whatever the yt equivalent is) - but to consider a few things. For example, in biomolecular evolution, certain plants develop things like poisons extremely rapidly, seemingly within a few generations. How is it possible for these plants to evolve the protein mechanisms neceseary to make such refined poisonous chemicals, any of which, a stray or missing hydrogen atom in their composition along the way will ultimately cause the "poison" - (which we are going to to infer was caused due to a survival of fittest paradigm where these chemicals are evolved as defense mechanisms) to fail because it has no potency with a specific rearrangement of these particular atoms. So, how do the plants know? Also, the plants do not possess scientific capability to potentiate its biochemicals through any other means then by allowing the ones who have produced the best and most potent poison the ability to reproduce more. The answer here, is that biomolecular evolution (a precursor to regular evoltuion) happens, in some cases, very, very fast on a relative evolutionary timeframe. And in some cases, it is explosive and exponential and never regressive in the "long run" when considering things on the cosmic scale. However, this notion does not discredit the video, because survival of the fittest is in theory something that will apply universally , across the entire cosmos, to every DNA and DNA-like-yielding organism. While we may not have come from the same baby-universe source of biochemical stew, we all, and all of our future generations until the end of time, will have to abide by its rules, and cosmic life will need to abide by its commonalities. Thus, this evolutionary clock may not be a great indicator of the past, but it could end up, with much fine tuning, to being an exemplary predictor of the future of universal life.
This was highly informative, and not just because it's the biggest "read more" drop down I've ever seen.
Probably the most thoughtful YT comment I've ever read. Kudos
Though we cannot use the evolutionary clock to confirm it, it doesn't outright reject the hypothesis that all life stems from a period where the entire universe was room-temperature does it?
I think bro likes his content
I recently conducted some research on the origin of life. To be frank, I'm not particularly fond of this video. As a scientific and informative channel, Kurzgesagt chose this topic and presented a highly debatable hypothesis, seemingly for the sake of garnering more views rather than promoting mainstream scientific consensus.
Now, we have knowledge that the Last Universal Common Ancestor (LUCA) existed around 4 billion years ago in hydrothermal vents, equipped with relatively intricate biological mechanisms, potentially capable of transcription and translation. Is it complex? Absolutely. Did life evolve too quickly on Earth? Not necessarily. Once the process of "selection" commenced, evolution played a role, and complexity could have been achieved relatively easily. "Selection" here refers to the molecules essential for primordial life. These molecules weren't randomly assembled by chance. Perhaps the pore size of hydrothermal vents favored larger molecules, or the aggregation of macromolecules facilitated the accumulation of these vital building blocks. Whatever the exact process, it led to the emergence of early life, and evolution took the reins from there.
Regrettably, the Pyramids and Moai statues were not constructed by aliens, mermaids don't sing to lure sailors into the sea, and the Loch Ness Monster remains a legendary creature with no verifiable evidence of existence. While some hypotheses lack concrete evidence, the idea of universal alien life may possess some basis. Nevertheless, it's crucial to prioritize scientifically sound and convincing theories, especially given the abundance of alternative hypotheses that are more plausible than this one.
I'm not entirely certain, but perhaps I simply prefer dry textbooks over audacious and groundbreaking perspectives.
Such a rare moment when Kurzgesagt creates a warming video as opposed to the usual ones with existential dread.
What are you talking about? They have plenty of videos on global warming.
Exactly, it's like a whole new genre I've never experienced before, the opposite of existential dread. Existential calmness? Existential joy?
I just got goosebumps from this video. Thanks to you guys a lot of people, myself included, started to read into scientific fields in order to think big.
Our universe is truly amazing and we humans need to stay alive. There's so much more to learn and achieve and I believe that we could do it. We only need time!
Imagine if this turns out to be true, that would mean that most lifeforms in the universe are related to the same ancestors. Incredible.
An Adam and Eve of sorts
Not necessarily. Just love created at the same time but millions and billions of times at the same time
You have to be crazy to believe this trash video 😂
If that is true then it is almost certain that there is other lifeforms in the solar system and maybe there is even some life underground on Mars.
so that's why most of the aliens look so similar on Star Trek
This left me speechless. The idea that life could be nearly as old as the universe and it being everywhere gave me a warm feeling, because if in the future if we do find alien, and if this is correct, we would know that we are all connected long long ago, like finding a cousin that you didn't even know existed. If this is true, then this could bring all life in the universe together, like a large branching family.
an amazing and awe inspiring thought
I'll try not to spoil it for you, but yes life/consciousness has existed since the big bang. Before it as well. Inorganic or interdimensional beings of energy exist in higher dimensions all around us
Do you have sources or did you just make it the fuck up? @@WILLed_into_Existence
@@WILLed_into_Existence you’re joking right
Not if, but when.
Thats the reason why we are so curious about the stars because in reality we are just homesick 😔
It feels like he is explaining the whole universe lore and drags us in. It feels like we are flying around with him. It’s so goooood!!
I love the idea that all life in the universe could share the same origin back in the early days, but have then evolved differently on each local biosphere. The miracle of life would have happen just once, which is statistically easier to believe, and then spread to every corner of existence.
That would kinda make any alien out there our very distant cousin, and that's a fantastic thought!
I find this idea very comforting, except for the fact that with each passing year the universe expands more and the chances of meeting our cousins grow weaker and weaker... :(
maybe the expansion was set, in order for us to not collide with other existence and cause galactic troubles
@@ak..4359imagine offending an alien so hard that they decided your kind wasn't worth it and just uses exterminatus
It isn't statistically easier to believe that life arose in a brief 7 million year period rather than in a period of over 500 million years.
@@ArawnOfAnnwn That is correct, if both periods had the same number of opportunities for life to arise per year.
But what's interesting is that, in this new model, there may have been bazillions to the bazillionth power more opportunities for life to arise during that 7 million year period (further shortened to 4 million if we account for needing the first 3 million years to produce heavy elements) than we previously thought, perhaps raising that likelihood enough to not seem strange at all, but almost expected.
Consider the sheer number of opportunities for life to arise if we're talking about an entire volume of a universe as being hospitable, versus just some tiny mass clumps at the bottom of vastly separated gravity wells like we see in the current universe. It's like the difference between a gallon of water and a gallon of rock with tiny bits of water trapped in points throughout it: the rock wouldn't just need 100 times more time, statistically speaking, to evolve life in its water, it would need a billion times more time (or some such huge number multiplier). Which is to say, the probability of life arising during that 4 million year window might be comparable to the probability of life arising during a 4 quadrillion year window on planets after the universe had cooled.
@@greenfinmusic5142 You're assuming that life arose in the middle of space in your model. It wouldn't, it would still need to form on large clumps of matter (at least for life as we know it, which is what this model is about anyway else there's no point postulating a temperature range to begin with). Temperature isn't everything, you also need other factors. Like pressure for instance. The universe wasn't just one giant ocean just cos the temperature was right. Water isn't liquid even at 10C if the pressure is too low. Then there's the needed elements, which the video mentioned but didn't dwell on much. Some are abundant sure, but phosphorus in particular is rare even today. You need them to not only exist, but exist together in sufficient concentrations in the right environment. And so on. Most of the universe was still not suitable even during that brief window. The themselves admitted they were simplifying a lot. The hypotheses sounds more likely than it is if you consider it from 10,000 ft up, but getting down close into the finer details and you'll find things aren't so easy. Hence why it's still just a speculative idea.
This is such a fascinating idea. I once had a cosmology/astronomy professor argue that it wouldn't matter whether life originated on Earth or elsewhere, because it would only move the problem: i.e. it would still not explain how it originated. However, this video makes me realise it may really make a difference.
For the first time the panspermia theory sounded actually exciting and not just like an excuse to not have to explain how life came to be here.

Very cool video, as usual! This one made me think of Octavia Butler and Earthseed right off; I think she would have loved this theory. Thanks for all your videos that make science accessible even for us language arts types :)
This actually kinda makes the absurd sense of scale of the universe a great deal more comforting than a lot of it is usually described. I hope these theories are true, they're quite lovely and to think we all have some great ancestors out there in the big expanse of this crazy universe, is a really cool sounding idea. Thank you for making this video, it's definitely going to my favorites.
This is complete pseudoscience
@@NPCSpotter That doesn't mean that one can't hope the theories are real. I mean there's still so much we don't know about the universe, it's not utterly impossible to fathom such ideas.
@@NPCSpotter pseudoscience is not the same as speculation/theory
what would be wild is finding aliens and finding out we have a common ancestor. Like what the heck?
@@NPCSpotterCheck the description, read the source. Scrutinize if you are so much inclined.
There's just something immensely wholesome behind the idea that the universe itself, through its very existence, _wants_ to have life in it.
There is self Organisation and the quantum foam is a source of endless possibility.
Also energy can not been created or destroyed.
So yes - the universe wants to watch itself through your eyes.
Giving a large amount of time, a monkey can type Shakespeare sonnet on a typewriter. I don t understand why are they amazed that life came into existence 500 minion years after the planet was formed. 500 milliohm years is a long time for things to happen and trial and errors to occur.

One pf the most inspiring videos ever made on this channel, superb jobs, wonderful animations, intriguing narrative. Astonishing.
I’ve been going through the lowest phase of my life throughout this past year. I cant begin to describe how much this video affected me. It’s been a very long time since I had that click in my brain, realizing something that seems so obvious and beautiful. Thank you, I will not forget this feeling ever.

I love Kurzgesagt videos in general, but I really feel like this is one of the best videos they’ve done in a while. I love the topics of space, time travel, life, etc and this video hit many great points. The visuals, the story/dialogue, and the soundtrack were all amazing 🫶🏼
my fav is The Egg - A Short Story, idk why but i love it.

@@TheCoolestLifeForm Ah, yes! The Egg is a great one, too!!
oh. I felt like this was one of their worst in a while.
Man this channel always seems to answer my questions the day I have them. These videos are seriously great.
Honestly the early universe sounds like a genuinely magical place, I hope sometime in my lifetime we work out some way to literally look into the past so I can see it
Y'know, a lot of the fans of this channel harp on the whole "ah yes, my daily dose of existential dread", but then they pump out occasional gems that just fill you with absolute wonder and fascination about our own universe, and it all makes it worth it.
Honestly, the so-called existential ideas are only existential if one is still reckoning with them. It's really a matter of perspective. I feel like people yearning for humanity or just life in general to "always" exist, are at their very core struggling with mortality. To accept that we are finite is a heavy thing, which can lead to a sense of hopelessness, which sadly keeps them from enjoying what existence they do have. Reckoning and then making peace with existential ideas is both difficult and important for one's personal growth.
@@bluemooninthedaylight8073 elaborate, I’m rather curious if I fall in the same category as the individuals whom you speak of.

I don't know why, but Kurzgesagt videos like this always make me so emotional. I think it's a combo of the awe and excitement, as well as the sadness that I doubt I'll see the answers in my lifetime.
Came to the comment section to say the same thing. Can't believe I'm sitting here crying over a science video, but here we are
Crying here
The science they explain is amazing but the existential dread I get from a lot of their videos is a bit too much for me. I think I will unsubscribe for a while and find something else to watch.
The James Webb Space Telescope has the ability to read exoplanet atmospheric compositions. They just detected a good indicator for microbial life on a super-Earth 124 lightyears away. Don't lose hope!
Although all of this is highly speculative and could very well be nonsense, I'm just blown away be the mere idea. It is so simple yet so ingenious and I never thought of anything like this. And the best part for me as a scientist is: it actually seems to make sense and feels like it could be true! 😃 I love you guys for giving me this inspiration today!
One of my friends brought up a very good point about this - at that point in the universe, there would have been so much radiation everywhere that it would be impossible for any life to survive. Regardless of temperature, nothing can survive being constantly crashed into by supercharged particles, certainly not tiny single celled organisms not that big compared to the radiation itself.
This is certainly true for life as we know it today. However, we don't know what such early proto-cells might have looked like. Maybe, they weren't too susceptible to radiation because they were just much simpler than anything that is alive on earth today.
Besides, I'd say it isn't clear whether the radiation was really everywhere. The video also talked about very early planets and asteroids. Inside those, there could have been cavities that were protected from radiation to some degree. Inside such caves, cell evolution might have been easier.
Every drop of water floating through the universe in amalgamations of all sizes would have been liquid, and would have essentially been its own petri dish. Unimaginably high numbers of opportunities for life to arise; almost infinite for practical purposes, which seemingly pushes the probability up into near certainty that life arose during that epoch.
@@TerpleDerp2600 The "Goldilocks zone" is a generic term for when things are just right for something to happen (not too hot/radioactive, not too cold/inert). We live in a Goldilocks zone of time and space which has allowed life to flourish for a few billion years without being catastrophically wiped out or simply not having the resources to get started in the first place, there is nothing to say that in the unimaginably vast history of the universe that such zones haven't existed before
@@TerpleDerp2600 however the seedlings talked about in the video are not fully formed microorganisms but just template genomes formed from simple elements
I've heard of this theory before, that we came from some other place. To me it makes Earth feel even more special, like it was just right for life. I really love everything about this channel, you're doing an amazing job every video and are excellent 'teachers'! Thank you!

i’ve never heard this theory before. im currently experiencing a sense of unimaginable awe bc it rly intuitively just makes so much sense as an explanation for why life was already so complex at the time soon after earth’s origin. it makes me even more burningly curious about what the mysterious heat source inside of Enceladus could be, or what it may be potentially sustaining
It's basically just an expansion on the theory of astrobiogenesis or "bioseeding"
You could search Google to find out why Enceladus is heated
Panspermia is a common theme in scifi.
Maybe life existed all over and has died everywhere and we are among the last left till we kill our planet like everyone else.
@@stevencooper4422 or 'panspermia' lol i feel like i prefer 'bioseeding' - but yea im familiar w those ideas, but the details that rly blew my mind about this one in particular were the increases of complexity delineated backwards to arrive approximately at the age of the universe being when the simplest genomes would have arisen assuming a consistent pattern, combined with the idea of the entire universe potentially having been a habitable zone for a time. something about the idea of life being ubiquitous and a built-in feature of the universe rit large as opposed to a random anomaly gives comfort to my heart and also does away with the fallacy of something self-sustaining and ridiculously complex coming about quickly in a universe dominated by entropy
We found it, the most optimistic Kurzgesagt video yet
I believe this is personally your most interesting video yet. It puts even more thought to how amazing it is that we're all here, at this time, in this place. The chances of everything that led to our existence are just so low, they're nearly zero. And yet, we exist.

I don't know why your videos about space always make me cry, but they do. Whether about celestial bodies or aliens, something about the cosmos is just so awe-inspiring that I end up getting overwhelmed.
The issue I see with the "Goldilocks universe" is that water remains liquid at a different temperature range at a given pressure. Reduce the pressure enough, and you will get water boiling at 0ºC. So it is not just "the universe went from too hot to too cold, so for a few years it was at the right temperature." Also, the idea that genetic material, no matter how different to the current one, could have stayed "dormant" for eons after the universe cooled is quite... radical.
It may have major holes in it as a theory, but I do like that it suggests a reasonable answer for the evolution of life.
Unlike the theories about the universe being a simulation, there would be tangible evidence that we could find to either support or refute this idea. I hope we can find that evidence to evaluate this theory, since it would be very useful to know what sort of origin life had.
I agree with your first point but, regardless of the actual temperature, there must have been a span of time when water or other substances would have been liquid.
And is the hard vacuum of space not the ideal environment for preserving something akin to DNA?
Pressure probably would have been higher in the denser universe, but yeah genetic material surviving cold, radiation and burning as a meteorite through an atmosphere sounds very unlikely. Maybe it's a "very low but not 0" probability situation.
Great point. The pressure of space would have been different back then though as matter was more dense. Would have been good for him to talk about this rather than just completely skipping over it
@@RootDubz93even though the density of space was far higher in the early universe it was still low enough that we would consider it hard vacuum in relation to the boiling point of water.
So water was probably gaseous in hotter regions and solid in cooler regions
This gave me goosebumps. To think that we might be the aliens other life could be looking for is mindblowing.

I just really loved the idea that there is a possibility the magnificent vast university we live in aren't a silent barren.
I'm having a bad time with my life and the theory just filled me with some joy. I always thought the universe is too beautiful to be left lifeless and I really appreciate the video alot.
Apart from the technical quality of the video (visuals, sound, creativity, animations, narration, text, etc) which always manages to stun us, this idea completely blew my mind! I've always been fascinated at scientific and cosmological/atronomical/universe theories, like going inside black holes, worm holes, etc, but I never seen anything comparable to this Goldilock Universe theory, this is just absolutely brilliant. Of course when it comes to science fiction/theories, there are just too many variables that need to go into account and that requires lots of studies and maths and proving to actually go on with the idea of it actually working, and that I leave it to actual theorists and physicists to do, but the base idea already overwhelmed me, who always thought about the universe in this way, teeming with life somewhere, but never EVERYWHERE... This has become my favorite theory.
Remember, just because it was hospitable everywhere does not mean that life evolved everywhere. It might have only happened a few times. Or maybe just once
That would mean the aquatic animals would look in general like a fish,flying species like the birds,reptiles,mamiferes and an inteligent specie(or more) walking on 2 legs and using its arms to manipulate tools and objects. That would explain the cases of alien kidnaping people and animals,maybe they had some cataclism (a gamma radiation burst from their sun) or nuclear war in their history,they maybe had their DNA damaged,so they collect samples of how DNA chain is originally to repair theirs,also explains why they are all described as humanoids.I'm not saying all the cases are real,but is also imposible that people from different parts of the planet to describe the same alien specie they encountered.
These visuals are tremendously impressive in so many galactic ways. Never have I ever imagined I would come across this channel out of the blue. Keep up the good work with all this. Even the dinosaurs want to be resurrected due to all the praise and recognition you’ve given them.

Greatly increasing the volume for life to evolve.... What an amazing and simple idea....
The music definitely adds.
I have a master degree in theoretical physics but this is for the first time I realized that there was a time when almost all of the Universe might have been habitable. I have never thought about that before. This video is a brilliant. It makes me feel shocked.
Similar boat for me. I had never considered that the window could be that long; I always assumed it only lasted a few seconds/minutes or some such scale of time, and also that there wouldn't have been any heavy elements around. Now I've got a 4 million year window to daydream about.
It's rare to encounter a brand new thought like this. Today is a good day :)

This is not my direct scientific field, but I have followed origin of life theories for quite awhile. While the genome size doubling is obviously majorly simplified as the video does suggest, I think it is a decent proxy. The exponential idea and reversing it was something I had never heard of before, and I think it is an absolutely stellar idea that carries some serious water. Thanks for introducing me to this concept! Definitely will be reading that source material.
kudos for "stellar" and "water." nice.
Well, there is such a thing as oversimplification, and IMHO the example of genome doubling was definitely such a thing.
And the reversal is seriously flawed as well, since we cannot at all assume that the same doubling rule can be applied to very simple genomes, which might evolve way more rapidly than complex genomes.
And no explanation how such extraterrestrial germs get to earth and survive getting here.
@@tobylegion6913 the explanation for life spreading across the universe was due to the fact that all water was liquid during that time. Life could easily hop from asteroid to asteroid, especially since everything was much closer together back then. 7 million years is easily enough time to travel across the galaxy.
@@tobylegion6913take a look at how certain microbes and tiny life can survive extreme conditions. These extremophiles (like the bacteria in hot springs or the classic water bears) have been found to withstand even the cold, hard vacuum of space through a sort of hibernation.

Every one of your videos just leave me with a gaping mouth, wide eyes and a new sence of wonder about the world.
Will go and Xmas shop to support you right now.
It is an impressive hypothesis. Two points that come to mind for me, in order in which they occurred, are as such:
1. Earth did indeed go from "infernal partially-molten rock" to "woah there's microorganisms everywhere" pretty quickly, on a cosmological scale. We do need to remember, though, that "a few hundred million years" is so far beyond our mortal comprehension as to be basically indistinguishable from eternity to us. Even 100 million years is an insane amount of time for potential reactions to occur, assuming suitable conditions hold; and, if the expansion of the genome was anything like the Big Bang itself, it's plausible that a very simple genome rapidly became a lot more complex for the sake of efficiency and potentially handling early competition from divided sibling-cells, before slowing down somewhat and "merely" doubling in length every few hundred million years.
2. That said, if this hypothesis does turn out to be accurate, the implication is that all life is indeed derived from a similar source, and therefore it is not at all implausible that aliens will eventually develop to be bipedal with two arms like humans, therefore justifying our innate desire to make extraterrestials look like us and/or sexy in media.
The ending of your comment threw me for a loop. Serious scientific thought followed by "this justifies sexy aliens". A+ analysis lmao
Even if life did first appear 10+ billion years ago, that doesn't mean there's only a single source. It's entirely possible for different locations to form very different building blocks of life and evolve completely separately.
@@TheFinalChaptersNot really.
Physics and chemistry.
Laws of Life.
Found Captain Kirk.
A technological species would be very similar to humans, or animal life on Earth in general. It would have to be mobile and terrestrial, so no sentient trees or fish or cloud creatures. It would need grasping hands and walking feet, albeit not necessarily the same number. It would most likely be radially or bilaterally symmetrical. It would need a large brain, and having the primary sensory organs close to the brain (a head) just makes sense. It would need to be social, so have some kind of system for precise vocalizations, and may as well put that mouth close to the brain too. There is nothing in chemistry that has the kind of versatility as carbon, so more than likely it's going to be carbon-based life as well.

@@phantomaviator1318 x)
who knows, humanoid species have only existed on earth for a very small amount of time when you think about it, and on the color of plants its probably dependent on the star if anything.
1) Probably they would not, if they have well enought technologies to make it to our system. I think that a swarm of nanites, when your personality (if is) is just a brain in a vat, would be the most effective way.
2) Probably, if star is a yellow dwarf like our Sun, it would be green, but not all plants even on our Earth are green.
This seems very plausible and there's something quite pleasing about it. Great video!
Every time I watch your space videos the more I like space and the more I research about space also I love your videos especially this one
Finally, a video addressing the fact that the universe at some point was more or less room temperature and all it could imply. I find it highly likely life originated around that point, and why it should be everywhere we look, although it seems to be extremely rare to develop into anything like us (Fermi paradox). Been wondering about this for many years, and with this video I feel like I just got granted another piece of the puzzle to understanding life and the universe.
Yeah I bet the pressure was perfect for water to be liquid too ;))
Yes! Room temp universe is what I thought to lol. Super cool concept, makes sense that it would nurture life
People will come up with any supernatural theory they can just to not admit that God exists. This is not based on science… this is based purely on faith. Abiogenesis is a supernatural event believed by faith without any evidence and upon this theory the entire secular history is built.
It's possible that at some point it was at the just right temperature of water for showering
The “universe was room temp” theory makes no sense. Space has no atmosphere or structure to contain any of the heat that the “big bang” potentially released. That heat would’ve instantly dissipated and any superheated gases would cool through radiation, as what happens with supernovas, making that room temperature period last very briefly and not millions of years.
This theory is by far the best I've ever heard about. The fact that the calculation for how quickly and complex life evolved, was within the timeframe of our early universe, is such an amazing alignment and literally shacked me happy with excitement and hope that it is true. Where the temperature was pleasant for life to exist literally everywhere, when the right elements are just present, is one heck of a theory. I really hope it is true, it would mean that there is life everywhere in the universe and that there is complex life on other planets for sure. It would also mean that we would all be related by one single cell. BY ONE SINGLE SELL EVERYTHING IN THIS UNIVERSE. HOW AMAZING IS THAT!?!?!? One of my favorite vids of all time now
It is a hypothesis, not a theory. But it is a cool hypothesis indeed.
@@christianadam2907 ah
@@thevutvut. 😊 A DNA sample would strengthen this or destroy it 👍 we will find out 🔭
Temperature isn't everything. Pressure and a whole host of other factors matter too, only one of which was covered in the video (availability of the necessary elements for life, though phosphorous in particular would likely still have been an issue).
If the entire universe (though significantly smaller than now) had the right conditions, there could be a lot more than one single cell that life evolved from

These videos about life on other planets are so touching. So odd to be sitting here crying over an science video, but it makes me feel so hopeful and somehow... not so alone in this crazy empty universe?
Thank you for the amazing work, you truly make science accessible in a completely different way
I adore the idea that we alongside any other possible species might all be related and fellow inheritors of the stars that shine on us.
Knowing how life tends to be kind of cynic on itself, its unlikely we will get along at first, but the possibility of spreading and traveling across the stars, together with any possible cosmic neighbors as the heirs and children of the big bang is something touching and beautiful to think of.
Really puts into perspective the idea that we are all the universe that is experiencing itself.
Children of the big bang❤ sounds so poetic
i love seeing the animation improve and get prettier and prettier. I also love the new alien birbs scattered through the videos
This video is absolutely astounding. The idea that at some point, the universe was warm enough to support life everywhere is both exciting and scary.
2:24 Thank you Kurzgesagt, for giving me my new nightmare:
A birb with a smiley face on it.
If this hypothesis is real then we can say for sure that we are not an outlier. If life truly evolved ~10 B years ago, older than so many stars including our own, then life is as much an intended part of the cosmic "system" as any star or galaxy is.
And this gives me the chills (in a good way)
If it were real, there would still be a good chance that humans are the only or one of the first intelligent species in the universe.
Are those chills... multiplying??
This is complete pseudoscience. Just a bunch of delusional scientists refusing to believe in a creator. Fan fic material right here
Hell yeah
This just makes the Fermi paradox worse by orders of magnitude, the simple observations of the lack of alien civilizations should be pretty direct evidence to refute this hypothesis.
