Comets are like stellar versions of pollinators or spore launchers when it comes to chemistry.
I was thinking "space sperm" while planets are the eggs. When enough "sperm" find a fertile" egg" you get life...But then I'm a sick puppy...
Not even focusing on the numerous limiting factors concerning the generation, viability and longevity of free floating amino acids.
Just the information paradox alone cannot be bypassed, causal potential within natural laws are incapable of producing viable proteins with the sufficient nucleotide arrangement required for viability both in survivability, functionality and most of all - replication.
Secular naturalists just keep reaching, the more complex life becomes the more you think it self generated without feasible natural functions that could actually result in organic nanomachinery (which proteins are).
Which is incredibly beautiful to think about

Hello wonderful peptides!
Sometimes its hard to not think of the Earth and our thin veil of survivable environment, as separate from the universe. All of these discoveries, amino acids, peptides, even DNA bases floating around the universe…..its wild.
Dude we’re like all connected.

In 1992-1994 I worked for a physicist professor Johnson who swore that he had perceived and measured simple amino acids and petites throughout the universe, and he claimed that only comets presented with the correct temperatures to generate these complex chemistry. He claimed that comets were seeding the universe with biological building blocks.
In particular, porphorines chemical structure were extremely common in the specs throughout the galaxy.
Did he ever publish anything about this? Would be fun to read about
Here on Earth all you need is obsidian and percolating water and it will build up everything you need to make RNA. The channel _Event Horizon_ by John Michael Godier has spoken about it a few times. He's actually citing this info from a written paper. He's gone pretty deep into, more than I can here.
@@pacotaco1246leaving a comment too, so I can get notified in case any papers are shared
Thank you so much for sharing your translations of scientific papers! We hobbyists appreciate you Anton. ❤
Absolutely ! Anton's is about the only Astronomical Website I Trust.
I remember the project Stardust, man time flies. This hypothesis was already around back then, it's sad it didn't became more popular because it makes the most sense. A detail you didn't mention and that few people know as well is that micro-meteorites coming from the comet's ejecta are so small that they cause no friction in the atmosphere while falling to Earth. But maybe you keep this for your next video 🙂
Wildest idea: comets are the ejecta from earth getting blasted by periodic biblical solar events. Hence the elliptical orbit. Also explains the organic local compounds.
That's actually quite an interesting idea. They could act as life preservers in a sense, allowing life to eventually reseed on worlds.

@@shaydorahl6740what are you yapping about dog
@@RussSmith uh no
From a chemistry standpoint, comets give us a much wider "natural" laboratory for the basics such as distilling that we assume happened on Earth over billions of years. It means that the high/low temperatures we normally use to try to figure out nature are much more intense than we normally screw around with in the lab. Normal chemistry in the past couple hundred years never had access to a freezing point close to absolute zero, along with zero gravity tossed on top for good luck. Abiogenesis seems so much easier using this perspective. Gr8! Peace ☮💜Love
The earths water did not come from comets. The isotope ratio is different
Source Deuterium-to-Hydrogen Ratio
Earth's Water 1:6,700
Comet Water Typically much higher (e.g., 1:1,900)
@@oldmech619 I wasn't referring to water, but thanks? How every molecule of water got to Earth wasn't on my mind, but the complexity of water depending on quantitative amounts does interest science and our gathering of knowledge while we're here on the planet. Gr8! Peace ☮💜Love
Fantastic insights! Thanks for sharing 👍
@@BrianFedirkoMaybe what we think of as the Biosphere needs be expanded to include the entire solar system, and possibly the galaxy.

Thank you, Anton for reading through all the stuff I cannot comprehend and making it comprehensible! ❤
I have for decades wondered what effect low temperature chemistry had on the origins of life. I think I saw an article in maybe the 1980s about how scientists had taken the sludge produced in one of the early attempts to replicate the conditions under which life developed, and froze it (the chemical sludge full of amino acids and other complex molecules). Think the Miller-Urey experiment from 1952 - that kind of research.
Years later, someone decided to analyze the frozen sludge and discovered that it hadn’t been sitting there, inert. Chemical reactions had continued to occur and now the molecules it contained were even more complex.
In cold temperatures, reactions happen more slowly. Perhaps these conditions were what allowed the first cells with a lipid membrane to slowly assemble and begin to develop metabolism and reproduction?
These cometary studies supply intriguing glimpses into the origins of life. Who knows? Perhaps life has developed on some of the ice moons with subsurface oceans? Instead of solar energy, it is the heat from gravitational tidal energy fueling such organisms.
I am a 70 year old boomer and I am sorry I won’t be alive long enough to see more such discoveries. But I will eagerly read and listen to whatever I can in the time I have left. Gen Z has a lot to look forward to!
No astonishment here. Except that it still astonishing.
Although I don't remember the details, this hypothesis was suggested years ago. Still a great video, thanks Anton!
Europa and Enceladus along with their parent planets and sibling moons cross the paths of various comets. They have most likely collected some amino acids and peptides too.
Amazing and mind-blowing. Thanks, Anton!
The point of this mission, known as STARDUST...
Im fascinated at how humanity is able to reach out and touch comets, and return to earth.
Merci Anton, this makes wonderful sense to me👍, I’m a believer😁.
Wonderful as always Anton. Thank you. ✌️😎
You rock Anton
Thank you Anton! I recently read that there are non-organic compounds in the earths mantle that are essential to the formation of life. Olivine is one of about 5. How about it?
This seems to make a lot of sense, and as a universal process, it could potentially seed life (or at least the building blocks of life) wherever it can take root. A fascinating episode and beautifully explained as always.
But doesnt the peptides/organic matirial break by the suns rediation in space ?
The galaxy, and the universe must be infested with life on any habitable zone planet in some form. This process creating peptide molecules would be ubiquitous throughout the entire universe.
"Must be infested with life ..." There is no independently verified 6σ evidence of non-terestrial life.
it's important to remember that life on earth basically formed the moment it could
Fenomenal vídeo! Very informative. Thank you.
This is the hypothesis i tend to be leaning towards, and that it's happening everywhere in the universe. All that is needed for life to start is a stable hospitable planet. We cant be alone in the universe, there has to be other life out there of some kind.
Oh wow I loved that aerogel trap dust test neatest shit I had seen to date at the time
Thank you, Anton 😁👍🖖✨️
This is incredible, and awesome
I remember watching that video in 2016, it was fascinating. Really interesting data, thanks
Highlight of my day
This has a beautiful implication
Comets are the universe's honeybees!
Thank you, Anton.
I like comets. Comets are beautiful and mysterious and kind of eerie in a way.
Imagine that. Somewhere out there beyond our reach someone is giving a talk on life dust across the universe and wondering if there is life like them and what they may look like.
Very interesting indeed, thanks 👍😊
I watched long time ago experiments in Japan shooting rocks against earth surface , surprisingly amino acids were produced by such a impact, they thought thats how life gets all it needed to start
we are still far away from knowing how it really went, maybe we will never find out.
Mind blown as usual Anton! But I'm confused about why peptides can survive in a meteor shower but not in a big chunk of comet. My (amateur) mind insists that they would survive better deep inside a bigger chunk of rock. It would be awesome to see a follow up episode on this! Peace brother 💛💙
Finally! Panspermia is slowly being redeemed. I've been waiting for this, for over 50 years.
Whyis46stillapedophileracistwarmonger?
I mean, it was always something that made sense... But, more than panspermia in the sense life traveling from planet to planet, or solar system to another, life might be just a intrinsic part of the structure of the universe... Like a completely unavoidable configuration of the matter... Salutes!!!

@@davidramirezrodriguez3373
I agree. Life, (or more precisely, it's "building blocks"), is more than likely ubiquitous across the Universe. However, if you espoused this just fifty years ago, you were labeled cuckoo.
I've always thought it quite arrogant and myopic, to think otherwise. Thank you, Abrahamic religion. 🙄
This isn't panspermia. Panspermia means life is transported on comets etc. from one planet to another, and this is abiogenesis beginning in space, instead of on surface of the planet.
Thank you Anton. Without your wonderful website, my understanding of these wonderful discoveries (made possible by modern technology) would be about 50% less than it is now !
Well, It may require a rewrite of Genasis but to my way of thinking it does two positive things for Humanity. One; It tells us we are ALL aliens so that ends that debate, Yes Johny There Are Alines, and you are one of them. TWO; It adds a new piece to the puzzle that we did not really have before in the evolution of the Humen race. God's brilliant and endless creation never ceases to amaze and entertain me. Think about the odds we as a species had to overcome just to get to crawl out of the soup and then swim. From there the odds of a single person to be here, now and the innumerable people that did not beat the odds and never got to exist. Yup, God Is great and I am blessed to be able to enjoy this universe. Thanks for another one Anton, Bless and be well all.
strikes me as an interesting version of the tidal pool theory. comets also receive cyclical heating and cooling, and apparently collect material from around the system like a dust bunny. perfect environment for chemical evolution to begin, or at least complexify. then deposit on earth, if done on a coast then these system spanning petri dishes now find themselves in an environment to continue complexifying even with materials that couldn't ever form on a coast like that. really interesting, should be able to calculate an estimate for how many comets earth needed before robust chemically diverse oceans were made and then see how long until life. the missing ingredient to abiogenesis is the diversity of chemistry as induced by the diversity of conditions met in various places in the solar system, deposit a couple billion years of said complexifying onto an early stabilized earth and boom, life.
As well as being rained down from comets, maybe the amino acids are introduced as the planets gets built - so life could originate in the centre of mini-planets and percolate out to the surface as they get bigger...?
.
That'd explain the Mole People and their planet-wide tunnels. 🤣
Unless there's some physical or chemical process out there we don't know about that would make the jump from peptides to proteins and then from proteins to cells, RNA and DNA extremely difficult...life MUST be everywhere.
Also where does this put the panpsermia hypothesis? If peptides can form and hang out in comets for billions of years, could entire dormant microbes do so as well?
I remember last year studying a lot of this stuff to write my university thesis. Amazing discoveries. I kind of believe that the comets could have been a key to bring on earth complex molecules to kickstart a process of abiogenesis here on earth, but really anything could be possible... maybe there are really multiple paths to develope life and maybe they are happening right now around the universe... so freaking cool. And scary. But mostly cool.
Makes a lot of sense
The intro to Spore was right all along
Super exciting, but I feel if it was that universal we would have biosignatures on semi and habitable worlds showing up a lot more. Really interested to see if more proof can be gained from further solar system study like Anton mentioned.
My trusted nightly video before bed
Comets giveth and comets taketh away.
Ok. I understand the sprinkle effect. Could a slow approached drop in ok or is it still no?
Personally, I suspect that exo-biogenesis occured in the cycle where interstellar dust grains collapse into proto-planetary disks and ejected when the proto-star ignites.
This gives biogenesis billions of years to occur over a galactic scale, rather than hundreds of millions of years on a planetary scale.
While technically obsolete, I highly recommend A.G. Cairns, "On the Mineral Origins of Life."
I think that comets are like cosmic sperm, and planets are like eggs, to ultimately unite into the self-awareness of the universe, which is manifested by some representatives of our species, albeit not as often as we would like.
Good to have as many possibilities on how life arose out of the Deep void of Space.
Thanks!
This was definitely intriguing. Thanks for info Anton!🪐
I am surprised the Japanese probe hayabusa isn't mentioned in this video. That probe found amino acids on an asteroid.
i've been saying for a while now that maybe life is really common, that once we get out into space more frequently that we will find life everywhere we go - the reason life is rare is not because it rarely starts but that it rarely survives. it has been suggested that life on earth, and in fact civilisations on earth, have happened more than once, humans have only been around for millions of years at most, how many times could life appear and be wiped out completely in a billion years?
There always seem to be so many moving parts to the creation of life it makes me wonder if there is a need for all the processes to be perfect or is there many combinations of factors that can create life.
There are so many comoving parts that it seems likely that not all of them are necessary for life, and if some were missing, life may look different but would still exist.
Life is a technology of sorts.
And worse, it is much more ruthless about recycling raw materials from obsolete prior versions.
We are going to have a real hard time sussing out the simpler prior versions, as pretty much in every environment they may have occured in their new name is "Nutrient Broth".
Define life and describe two independent examples. I was not able to ever answer that question@@AR0ACE
It's the mushroom. The spores hitch rides on comets. Sometimes they try to metabolize them if the conditions are right. The comets bring the spores to planets and the spores do the rest.
7:07 "flavors" 💀
If life comes from a comet, just makes the question bigger, how did life form on that comet? If it is from a destroyed planet that had life, how was it created there?
Interesting hypothesis, seems logical
Life self-assembles & evolved under favourable conditions.
I recall an experiment in which electrical discharges in a mixture of gases led to the formation of amino acids.
It's not to hard to imagine comets harboring such 'experiments', but under very different conditions.
Ionizing radiation, solar wind ions, heating/cooling cycles could drive chemical reactions.
Earth-side amino acids + cometary dust = chemistry of life?
Those experiments failed to produce life.
Miller-Urey experiment.
They weren't supposed to produce life
They were supposed to create amino acids without any lifeforms making it. Since up until then the only way we knew they could be made was by a lifeform@@douglaswilkinson5700
Shortly, comets roaming around is actually sowing potential life.
Cool!
Comets took our jobs. 😋
They took uhr dur
Also a great source of science fiction movies.
I'm betting it was a meteor that crashed next to a volcanic vent which was cyclically depositing heat energy and light elements like sulfur compounds to liberate heavy elements from the meteor, and that produced the energy conditions that would benefit from being replicated inside of a cell.
Panspermia for sure hopefully the origins of where this is coming from doesn’t impede more nuanced forms of where it all came from.
cosmozoa hypothesis is fascinating and terrifying
I always had thought that too..
More like on earth when plants pollinate there seed into the air.
Seed of life
Is there any way to analyze the ejecta from comets we observe today to see if these amino acids survive their journey through the atmosphere?
"We are all made of stars." ~ Moby 🤓
Long time fan and not a chemistry/biology expert. Would liquid water on a planet/moon be needed for these polypeptides to create life? Or could polypeptides create life on a moon/planet with for example liquid methane or some other liquid compound other than water? If that were possible, then I imagine the goldilox zone around a star could be MUCH larger.
Paptides as the base for peptines !! From the comet.
ohh thats huge
While we may have received some water from a comet here and there, I can't grasp how that would result in the massive amount of water not on;y on earth but possibly on other moons and planets that has been reported.
This comet is wild
Hypothetically is an ice comet breaks up into a very large but spread out stream of ice like a river. Could the earth pass through it and somejow have comet rain
The comets delivered the mice, and they kicked off the computation; the rest is history.
Just the shear complexity of it all - it’s amazing. The comets are like giant viruses carrying around genetic information, hitting a planet and making the planet start life. The time scale is unfathomable. The gods really are up in the heavens😮 lol jk, just rocks. Next time I see Hallie’s comet I’ll say thank for the peptides.
carbon/iron mixtures that we've never seen before? space steel! mine that comet!
I mean earth is a big ass comet and it is where we find life, considering what comets are this really just makes sense
Space rocks related to life on a big space rock - shocking news
Casually proving that life isn’t random
This is nuts.
Wild
All talk of extraterrestrial life is MOOT until we simulator abiogenesis in a lab. That will finally give us a ballpark number on how rare life is
Insane how many things had to go right for the formation of life to occur... Much less evolve into hairless bipedal intelligent apes.... Wonderful.
Hello anton i am off topic but there are 4 CMEs coming i think ill get a month of supply or if you say to not worry ill will feel better 😅
The universe is throbbing with life. It's a life creation machine.
There is no independently verifiable 6σ evidence of non-terestrial life.
So, apparently, we are all space travelers. Without the fancy suit. Got it.
Life does find a way
Evan granting that all these molecules are on comets their delivery to the Earth would not provide a sufficiently concentrated solution to accomplish anything.

Just the information paradox alone cannot be bypassed, causal potential within natural laws are incapable of producing viable proteins with the sufficient nucleotide arrangement required for viability both in survivability, functionality and most of all - replication.
Secular naturalists just keep reaching, the more complex life becomes the more you think it self generated without feasible natural functions that could actually result in organic nanomachinery (which proteins are).
Supernatitalists have no evidence that magic was needed
Naturalists are content knowing that 100% of the things we once didn't know ended up having a proven natural explanation
Oh, and the information paradox is about black holes and what happens to the information of an object that falls into them. It's not at all relevant here
The leading hypothesis is that life was extremely simple when it first formed and increased in complexity as it evolved. Not that it arose complex
Is he doing it on purpose, I mean the smile at the end
How many silicates are on the moon? If you know anything reports , that would be cool to hear.
