Something I've wondered about is the ability to harness fire as a great filter. At least for intelligent life. It's been crucial for humans to develop increased mental capacity, for working metal and more. But also, there's a small window of just the right oxygen levels for fire to be harnessed. Too little and you can't have fire, too much and it's too dangerous. Think it's like 14% to 21/23% is the atmospheric O2 levels to be just right. And what about our trees and wood being basically perfect for burning. What about a planet where there is no analog for wood? Id love to see a video exploring this, and any way a species could become a technological civilization without the same access and control of fire that we've had
Interestingly enough, it has been theorized that the land plants since the carboniferous have been the Oxygen-stat controlling and stabilizing atmospheric O2. Annual terrestrial cellulosic production is balanced by aerobic decomposition and wildfires. If O2 goes too high, even green or wet wood will combust, pulling gigatons of O2 out of the atmosphere almost instantly (in geologic time) as the forests and soils all burn. Ocean geochemical cycles, though bigger, aren't generally able to operate on as rapid a response loop.

My pet theory: life started deep underground in warm, wet micro-fissures, an environment not so different from, and in some ways maybe better than, a volcanic vent. If so, there might be life in almost every rocky planet, moon and asteroid in the universe that retains any warmth in its core and liquid water at some depth.
I like that theory. My own pet theory is that the first life may have arisen out of the natural growth of crystals. That could have happened within the micro fissures.
Yeah I also suspect this to be the case particularly since analyses looking for deeply conserved genes likely shared by our Last Universal Common Ancestor haven't found any evidence for genes related to cell membranes, You have genes for iron mediated chemosynthesis/respiration (which in modern life depends on ATP which itself depends on reduced iron based enzymes as a catalyst) and genetic replication(which in all known modern life depend on reduced iron mediated chemical reactions)but nothing related to membranes under supercritical conditions you can presumably catalyze. So metabolism and genetic replication but no cell membranes what kind of conditions could allow that to proliferate or function? The answer turns out to be rock cavities or inclusions like those found deep in hydrothermal systems. There is even some evidence which based on studying impacts suggests that the force of such an impact creates lots of spongey/porous rock the exact sort of conditions which such "proto life" might have needed to thrive before a mechanism to encapsulate genetic material catalyzed metabolism could evolve. Its even possible in principal that if this was the case then such proto-life might still exist deep down within the hydrothermal and or magmatic plumbing of active volcanoes on Earth. We naturally wouldn't have found it yet because we have been looking in far more "hospitable" (to Us) conditions near the surface rather than kilometers below the surface under hundred to potentially thousands of degrees temperature. I wonder has anyone looked at the stability of RNA or RNA like molecules under supercritical high temperature and pressure conditions? I would guess not since those are a bit more extreme than most laboratory conditions can handle.
Considering there are rivers and lakes almost everywhere underground, this is very possible. In many areas there is more water underground than on the surface. Where I live, you can drill anywhere 100 to 200 feet and have almost unlimited water. Even 5 feet in a lot of places you will hit water, just not clear water.
Certain fish can be counted as "land builders",as their droppings make up sand. Some tropical islands, especially the ones with beautiful "white sand",have fish that eat the coral and the "beautiful white sand" is what comes out their back end and ends up making the beaches.
The beaches of Jervis Bay in NSW Australia are exactly that, the sand are some of the whitest in the world. I use to tell my friends the sand is poop from fish that ate coral, but they didn't believe me

Excellent video. Another one of many. The idea that came to my mind after watching it is that maybe complex and intelligent life is actually pretty rare and so if any aliens ever discover that we are here (maybe they already did?) they would most likely be very interested, no matter how technologically advanced they were. We seem to underappreciate, at times, how miraculous our existence is, given the circumstances.
Don't get me wrong, the existence of life is truly miraculous real magic. That said you're taking for granted life is indeed rare. Fact is we don't have a good way to look for life on another heavenly body in our own solar system, much less another star system. The whole Fermi paradox hinges on the assumption intelligent species would be directly blasting us with radio waves from across the galaxy, which seems unlikely. The universe could be teeming life, with intelligent species relatively rare, but even if they had a way to confirm life on Earth from 400 LY away, what would they do about it? Light only moves so fast.
@@zachb8012 Yeah, what if their technology doesn't use any radio waves? Isn't it faster and better to send data through wires like Comcast cable? I'd think that they might quit using wireless or not even develop it. Or, if they do, say satellite based communications, then they could use light ... much more energy efficient and incredibly faster. So, aliens out there could be using fiber cables even faster & cheaper. So, just because we're not getting bombarded by radio waves (as you say, @Zach), I agree that lot of life could be out there -- that we haven't even begun to identify and can't identify because of what technologies they are using.
The best definition I've heard for life is that it is a self-organizing, self-replicating system utilizing cyclical flows of energy. That suggests we should be looking not for water, but energy. Hence, Io.
16:41 Europa, not Io. “All these worlds are yours. Except Europa. Attempt no landing there.” So we were warned in '2010: Odyssey Two', by Arthur C. Clarke.
:) Yeah. Just adding what little I've seen so far: they're officially NOT balloons and the United States doesn't know HOW these devices would stay aloft, as yet. Nothing is off the table. This according to mainstream media sources I've seen on freakin' Yahoo! =))
My thoughts so far are we really need more data. We know the first one was a Chinese balloon, but what these new developments represent is up in the air.
so just what is the recipe for this mysterious process 'abiogenesis'? sure, all the constituent ingredients are ubiquitous, but what is the recipe? i have a closet full of flour and sugar and soda, but that doesn't make a cake.
It seems that super Earth's will tend to be water worlds if they are in the habitable zone. Smaller planets like Earth can have high mountains but gravity would keep most of the land low on super Earths. So any water will tend to just spread all over. They would be somewhere between Earth and ice giants like Neptune. In the habitable zone, such a planet would probably still be most inhospitable, with a very dense and hot atmosphere, with the water vapour having a strong greenhouse effect. The air pressure would be severe. In a sense, these conditions may have echoed those of the early Earth at some stages. Also, deep down at the bottom of a water world ocean, the oceans could be so deep that it becomes ice 7 at the floor, making it difficult for the rock to interact much with the ocean. Perhaps a collision like Theia could remove some excess water, making the oceans shallow enough to be enriched by black smokers. I think it's possible that abiogenesis was happening a number of times before the Great Oxygenation Event seemingly rendered the planet non-urable. However, as soon as new life evolved back then, the "new kids" wouldn't be able to compete with the seniors. Abiogenesis might have a range of triggers (especially given how quickly it happened here)
The "urability problem" and the "water paradox" are two concepts related to the sustainability of human societies. The urability problem refers to the fact that, despite our advanced technological capabilities, human societies still struggle to create long-lasting systems that can support future generations. This is especially relevant when it comes to issues like climate change, resource depletion, and environmental degradation. While we have the tools and knowledge to address these problems, we often struggle to implement effective solutions that can stand the test of time. The water paradox, on the other hand, refers to the fact that while water is one of the most abundant and essential resources on the planet, it is also one of the most scarce and poorly managed. The paradox arises from the fact that even though water is essential to all forms of life and to many human activities, it is often taken for granted and poorly managed. This can lead to water shortages, pollution, and conflicts over water resources. Both of these concepts highlight the need for sustainable and responsible management of natural resources, as well as the importance of taking a long-term perspective when it comes to addressing global challenges. To tackle these problems, we need to develop innovative solutions that prioritize environmental sustainability, social equity, and economic prosperity.
If our solar system had three rocky planets which could've developed life and still has one remaining after billions of years, then it's a fair assumption that other star systems probably have them too. The more time passes, the more we discover that we're not as special as we once thought.
Interesting but I had the opposite reaction. While it’s cool to find rocky worlds with generally appropriate conditions for life, the hit rate of actually developing complex life on such planets might not be that good. We may not be “special” but we might be a rare anomaly- perhaps so much so that it will be very hard to find any others… and thus we could seem kind of special after all…
I think it's safe to say Earth's status as a habitable world (for billions of years) with a technological civilization is pretty damn special in a universe full of threats to such a situation lasting, or even arising. There's a reason the Fermi Paradox is a thing, and the dearth of observational evidence of advanced civilizations makes it pretty clear this is rare. Maybe not exclusive, but certainly rare.
To the stars, that is where our understanding of "world" has to go. Only this way we can understand who we are, why we exist, find a point and meaning in thriving for generations. We have a whole galaxy to explore, just by itself it is worth to exist and do all the things that lead to our goal.
I'm forgetting what we're calling the protoplanet fragments we're detecting in the mantle (there's 2 big ones) but considering the billions of years since collision with *Theia protoplanet, could it be that such fragments 'stirring' the mantle + Uranium in core = One of the solutions to Fermi Paradox? IE something helping to keep the mantle liquid AND molten is key to any sort of long-term plate tectonics, which being semi-disruptive (via volcanism) also pushes evolution (to prevent stagnation). Without the fragments OR the uranium the mantle could have maybe cooled faster.
Oddly enough, I've had dreams like that all my life. Not all the time but every few years or so my beach returns with its pumice islands floating in the bay. :)
The possibility of ammo acids to organize themselves to form one protein, let alone many, seems so unlikely as to not be possible. That's not to mention proteins forming a single cell, let alone many and then somehow becoming "alive" all on its own even more impossible. I hope I live to see the day where we have a better understanding of how this happened.
There is an habitat that nobody considers yet: great impact craters. A large impact crater forms a hot basin that will accumulate rain and rivers waters, and after some time, salt will accumulate in this place, harboring a differentiated habitat in a life-friendly environment . Best example is Sigsbee Escarpment, a giant salt deposit. What the relation of it with a crater? By my theory, 201.4 million years ago a 1,000 km impact crater caused the Central Atlantic Magmatic Proviince that resulted in the Triassic-Jurassic Extinction. Evidendce of its ring is the Lesser Antilles Volcanic Arc and the semicircular rock formation of Eagle Mills, dated from that epoch. Both are semicrcles sized roughly 1,000 km. Tectonic plates drifting apart cut the crater in two halves, the continental half is heavily eroded, but its rocks were dated precisely with the age of 201 My. The explanation for the Antilles Arc, of a colision of tectonic plates, is unsubstantiated. Its datation of few millions years ago is based on accessible rocks near the Earth surface; someday scientists will find rocks dating from 201 Mya also in that region, as way al slready done in Eagle Mills. The matter is complex, anybody interested on knowing my scientific evidence, it will be a pleasure to talk about it.
Not only could water in the habitable region be rare, we also need a large moon to create tides and stir the oceans. Then once we have the water, rain will remove atmospheric CO2. So we need a perfect amount of volcanism to replenish the CO2 to counter the rain removing it. But it must be balanced so we have enough CO2, but too much volcanism and we end up like Venus. These are just a couple things that must be perfect for billions of years for a planet to evolve intelligent life. The odds are so poor, it's a good thing space and time are so vast, if not infinite.
What if an answer to the Fermi Paradox is just that Aliens don't have technologies that use radio waves? Isn't it faster and better to send data through wires like Comcast cable? I'd think that they might quit using wireless or not even develop it. Or, if they do, say satellite based communications, then they could use light ... much more energy efficient and incredibly faster. So, aliens out there could be using fiber cables even faster & cheaper. So, just because we're not getting bombarded by radio waves (as asked by @Zach below), I agree that lot of life could be out there -- that we haven't even begun to identify and can't identify because of what technologies they are using.
I think we're being a bit to narrowly focused on how life starts. For all we know, there could be many paths that lead to the same end. We just accomplished it in a corrosive atmosphere, which may be unique in itself. Let's not blind ourselves with our biases and expectations. Life, loosely defined, may be widespread, with some percentage of this life persisting long enough to gain sentience. IMO.
No doubt the development of life, and in particular advanced life, is rare. However, with an estimated 2 trillion galaxies each containing hundreds of billions of stars, the universe is likely teeming with life even if it's only on 1 in a million exoplanets or less. But the sheer vastness of space and time have prevented contact and likely always will.
can you do a video talking about why titan isnt like earth with lots of trees and animals since it has liquid and we have made a hypothetical cell that could live there yet we havent found anything
There remains the currently unanswerable additional question - how many viable pathways of abiogenesis could there actually be? Is the way life arose on Earth the ONLY way life can arise in this universe, or could there be other sets of starting conditions and pathways that could also suffice? Without even knowing how abiogenesis arose here on Earth, there's no way we can answer this question, but if there are more ways for abiogenesis to occur than just the pathway that Earth took, then what we learn about the origin of Earth's life will not necessarily be generalizable to the universe at large, and will not be able to inform us on the Fermi Paradox.
why is the relative abundance of elements in our galaxy, in our solar system, in our gas giants, and in our sun so consistent yet so different from the elements found on earth?
Hey jmg! What do you think of the ufo phenomenon that’s been going on recently? Is it political tensions regarding not wanting to seem incompetent, or is the lack of information about the objects speeds and dimensions conspiratorial perhaps? Idk just thought it was very weird
To be honest, I don't yet know what to think. We don't have a lot of information yet. But I'd tend to agree, it seems very likely that it's some espionage operation by China and or perhaps Russia followed by a questionable response. What will be telling is if in two weeks time we still haven't been told anything of substance.
I've often wondered about whether or not Earth is occasionally spawning new life here and there. I never thought about the possibility that the modern biosphere might not allow that to happen anymore.
One more point if you will indulge me: I find it hard to imagine life growing up in fresh water as the dialectic charge resulting from the pumping of salt ions across cell membranes is literally the very fundament of the metabolism of all life on earth and most of the oldest and least changing enzymes common to all branches of the tree of life on earth are ion pumps suggesting to me the unlikelihood of anything earlier which now leaves no trace in the genetic structure of life to be suspiciously improbable. These ion pump enzymes are so fundamental not just because of their high invariance across the tree of life but also their forming the basis of so many other, often themselves highly fundamental, proteins and enzymes found across the ToL.
So from what I have seen in this and a few other videos? -- There's apparently water/carbon based life that does metabolism with phosphorus, and then there's everything else, that has to do it with iron, arsenic, whatever else works. -- And apparently, the water/carbon combination works out best for the relatively temperate and generalist-friendly conditions of Earth. If you're looking for carbon-silicon or silicon based life, you'll have to look up rarities in extreme environments, or places where heat, cold or acidity favor the different chemistry. -- This would imply that as long as the metabolic chemistry is the same (phosphorus-driven or otherwise), then water/carbon life is going to largely be compatible with itself wherever you go, and that there MIGHT even be future medical technologies that would allow exotic iron-metabolism life to be made compatible with its phosphorus-driven counterpart. -- Meaning we're way closer to _Star Trek_ convergence and commonality than we are to a "mutually poisonous" scenario where life exists but can never make direct contact with us, or us with them, due to the chemical differences from the Periodic Table. So, good for some mutual contact (eventually) but also bad if you consider that contact includes microbes and diseases. Strange days indeed. Especially with our suddenly going from shooting Chinese surveillance balloons to shooting at . . .whatever those three things were. ;) Here's hoping we didn't ventilate our version of Kal-el. =))

It's interesting that assuming life developed on earth we dont see other independent examples of the process that we can study. It's seems like it happened once a long time ago and then those conditions have never been met again, or at least we have never found them. I wonder why that is? If earth is such a great place for life why don't we see more recent independent examples of life arising?
It may be that several similar options appeared and then earth got free oxygen. That alone could have wiped out most contenders and prevented new ones.
Maybe they smelt with ocean lava and use biocomputers made from jellyfish and sea cucumbers. Just different tech. Possibly more carefully crafted than our fire and hammer methods.
I don't like the story very much in 'songs of distant earth'. However the world-state Clarke creates is one of his best, as is the elegiac tone of his prose. In my opinion it is only bettered by 'Childhood's End' which I consider to be his best book. It is _also_ about evolution and the transition of life... Ironically in 2010 super-Bowman makes only a trivial examination of Io, his interest primarily focussed the native life below Europa's surface and in the cloud-banks of Jupiter itself. Given what he does to the gas giant and the likely effect on the first moon that was probably wise!

So, just because we're not getting bombarded by radio waves (as you say, @Zach), I agree that lot of life could be out there -- that we haven't even begun to identify and can't identify because of what technologies they are using.
Did I hear you right, you're a fellow child of st Louis? Is so, that's awesome, I've been listening to your content for years.
You did indeed. I was born in St. Louis, MO.
The Great Oxygenation event reminds me of the process by which yeast creates alcohol which it can live within but almost nothing else can.
I love your brain,, Mr Godier.
Brilliant as always
The news that salty oceans may not host early life really put a bitter taste in my mouth.
2:00. It’s easy to imagine if you try, John. 👍🏻
The best definition I've heard for life is that it is a self-organizing, self-replicating system utilizing cyclical flows of energy. That suggests we should be looking not for water, but energy. Hence, Io.
16:41 Europa, not Io.
“All these worlds are yours. Except Europa. Attempt no landing there.” So we were warned in '2010: Odyssey Two', by Arthur C. Clarke.
Yes, I thought I had experienced the "Mandela Effect" again. Europa not Io.
Any thoughts on all the UAPs being shot down over North America right now??
:) Yeah. Just adding what little I've seen so far: they're officially NOT balloons and the United States doesn't know HOW these devices would stay aloft, as yet. Nothing is off the table.
This according to mainstream media sources I've seen on freakin' Yahoo! =))
My thoughts so far are we really need more data. We know the first one was a Chinese balloon, but what these new developments represent is up in the air.
so just what is the recipe for this mysterious process 'abiogenesis'? sure, all the constituent ingredients are ubiquitous, but what is the recipe? i have a closet full of flour and sugar and soda, but that doesn't make a cake.
Great video 👌👍😍
Great video!
JMG ought to create a set of space trading cards. Imagine how cool that would be!
It seems that super Earth's will tend to be water worlds if they are in the habitable zone. Smaller planets like Earth can have high mountains but gravity would keep most of the land low on super Earths. So any water will tend to just spread all over. They would be somewhere between Earth and ice giants like Neptune. In the habitable zone, such a planet would probably still be most inhospitable, with a very dense and hot atmosphere, with the water vapour having a strong greenhouse effect. The air pressure would be severe. In a sense, these conditions may have echoed those of the early Earth at some stages.
Also, deep down at the bottom of a water world ocean, the oceans could be so deep that it becomes ice 7 at the floor, making it difficult for the rock to interact much with the ocean. Perhaps a collision like Theia could remove some excess water, making the oceans shallow enough to be enriched by black smokers.
I think it's possible that abiogenesis was happening a number of times before the Great Oxygenation Event seemingly rendered the planet non-urable. However, as soon as new life evolved back then, the "new kids" wouldn't be able to compete with the seniors. Abiogenesis might have a range of triggers (especially given how quickly it happened here)
As I remembered Arthur C. Clark's 2010, the quote is: "All These Worlds are yours, except Europa, attempt no landing there."
The "urability problem" and the "water paradox" are two concepts related to the sustainability of human societies.
The urability problem refers to the fact that, despite our advanced technological capabilities, human societies still struggle to create long-lasting systems that can support future generations. This is especially relevant when it comes to issues like climate change, resource depletion, and environmental degradation. While we have the tools and knowledge to address these problems, we often struggle to implement effective solutions that can stand the test of time.
The water paradox, on the other hand, refers to the fact that while water is one of the most abundant and essential resources on the planet, it is also one of the most scarce and poorly managed. The paradox arises from the fact that even though water is essential to all forms of life and to many human activities, it is often taken for granted and poorly managed. This can lead to water shortages, pollution, and conflicts over water resources.
Both of these concepts highlight the need for sustainable and responsible management of natural resources, as well as the importance of taking a long-term perspective when it comes to addressing global challenges. To tackle these problems, we need to develop innovative solutions that prioritize environmental sustainability, social equity, and economic prosperity.
Sources for life first developing in fresh water and on land being more favorable to oceanic hydrothermal vents?
If our solar system had three rocky planets which could've developed life and still has one remaining after billions of years, then it's a fair assumption that other star systems probably have them too. The more time passes, the more we discover that we're not as special as we once thought.
Depends on the scale. From space we look like grey mold on a green fruit. And we dont act so differently. We are not special.
Interesting but I had the opposite reaction. While it’s cool to find rocky worlds with generally appropriate conditions for life, the hit rate of actually developing complex life on such planets might not be that good. We may not be “special” but we might be a rare anomaly- perhaps so much so that it will be very hard to find any others… and thus we could seem kind of special after all…
I think it's safe to say Earth's status as a habitable world (for billions of years) with a technological civilization is pretty damn special in a universe full of threats to such a situation lasting, or even arising. There's a reason the Fermi Paradox is a thing, and the dearth of observational evidence of advanced civilizations makes it pretty clear this is rare. Maybe not exclusive, but certainly rare.
Great listening to you whilst I fall asleep 👽
I listen to JMG to go to sleep...I end up staying awake because the information is intriguing.
To the stars, that is where our understanding of "world" has to go. Only this way we can understand who we are, why we exist, find a point and meaning in thriving for generations. We have a whole galaxy to explore, just by itself it is worth to exist and do all the things that lead to our goal.
I'm forgetting what we're calling the protoplanet fragments we're detecting in the mantle (there's 2 big ones)
but considering the billions of years since collision with *Theia protoplanet, could it be that such fragments 'stirring' the mantle + Uranium in core = One of the solutions to Fermi Paradox?
IE something helping to keep the mantle liquid AND molten is key to any sort of long-term plate tectonics, which being semi-disruptive (via volcanism) also pushes evolution (to prevent stagnation). Without the fragments OR the uranium the mantle could have maybe cooled faster.
A water world with continents of pumice would be a cool story setting.
People would have very smooth feet
@@hakrj12 LOL! I could do with that. ;)
Oddly enough, I've had dreams like that all my life. Not all the time but every few years or so my beach returns with its pumice islands floating in the bay. :)
Right!
If I remember right, the Blue Jewel description is from the Silver Surfer.
The word "urable" or "urability" is somehow hard to google for... whats the difference between urable and durable?
The possibility of ammo acids to organize themselves to form one protein, let alone many, seems so unlikely as to not be possible.
That's not to mention proteins forming a single cell, let alone many and then somehow becoming "alive" all on its own even more impossible.
I hope I live to see the day where we have a better understanding of how this happened.
And yet here we are.
Sad to think that we have knowledge like this, but some people still have the nerve to say that our civilization or that life on earth is not special.
Did you mention an interview with Damer and/or Deamer ? When and a link please.
It will debut a week from Thursday on Event Horizon, but a full hour interview with Dr. Deamer has already been recorded.

There is an habitat that nobody considers yet: great impact craters. A large impact crater forms a hot basin that will accumulate rain and rivers waters, and after some time, salt will accumulate in this place, harboring a differentiated habitat in a life-friendly environment . Best example is Sigsbee Escarpment, a giant salt deposit. What the relation of it with a crater? By my theory, 201.4 million years ago a 1,000 km impact crater caused the Central Atlantic Magmatic Proviince that resulted in the Triassic-Jurassic Extinction. Evidendce of its ring is the Lesser Antilles Volcanic Arc and the semicircular rock formation of Eagle Mills, dated from that epoch. Both are semicrcles sized roughly 1,000 km. Tectonic plates drifting apart cut the crater in two halves, the continental half is heavily eroded, but its rocks were dated precisely with the age of 201 My. The explanation for the Antilles Arc, of a colision of tectonic plates, is unsubstantiated. Its datation of few millions years ago is based on accessible rocks near the Earth surface; someday scientists will find rocks dating from 201 Mya also in that region, as way al slready done in Eagle Mills. The matter is complex, anybody interested on knowing my scientific evidence, it will be a pleasure to talk about it.
Not only could water in the habitable region be rare, we also need a large moon to create tides and stir the oceans. Then once we have the water, rain will remove atmospheric CO2. So we need a perfect amount of volcanism to replenish the CO2 to counter the rain removing it. But it must be balanced so we have enough CO2, but too much volcanism and we end up like Venus. These are just a couple things that must be perfect for billions of years for a planet to evolve intelligent life. The odds are so poor, it's a good thing space and time are so vast, if not infinite.
What if an answer to the Fermi Paradox is just that Aliens don't have technologies that use radio waves? Isn't it faster and better to send data through wires like Comcast cable? I'd think that they might quit using wireless or not even develop it. Or, if they do, say satellite based communications, then they could use light ... much more energy efficient and incredibly faster. So, aliens out there could be using fiber cables even faster & cheaper. So, just because we're not getting bombarded by radio waves (as asked by @Zach below), I agree that lot of life could be out there -- that we haven't even begun to identify and can't identify because of what technologies they are using.
I think we're being a bit to narrowly focused on how life starts. For all we know, there could be many paths that lead to the same end. We just accomplished it in a corrosive atmosphere, which may be unique in itself.
Let's not blind ourselves with our biases and expectations. Life, loosely defined, may be widespread, with some percentage of this life persisting long enough to gain sentience. IMO.
clap-clap!!! (I have been waiting for this post!)
No doubt the development of life, and in particular advanced life, is rare. However, with an estimated 2 trillion galaxies each containing hundreds of billions of stars, the universe is likely teeming with life even if it's only on 1 in a million exoplanets or less. But the sheer vastness of space and time have prevented contact and likely always will.
Concur. There is no evidence for life elsewhere and we will be lucky if there's even one other life-world in our galaxy.
Im pretty sure were just such horrible creatures we've been banished 😂
...or....the entire universe exists to provide that one small area where life can happen. Our planet is incredibly fine tuned for life....
can you do a video talking about why titan isnt like earth with lots of trees and animals since it has liquid and we have made a hypothetical cell that could live there yet we havent found anything
There remains the currently unanswerable additional question - how many viable pathways of abiogenesis could there actually be? Is the way life arose on Earth the ONLY way life can arise in this universe, or could there be other sets of starting conditions and pathways that could also suffice? Without even knowing how abiogenesis arose here on Earth, there's no way we can answer this question, but if there are more ways for abiogenesis to occur than just the pathway that Earth took, then what we learn about the origin of Earth's life will not necessarily be generalizable to the universe at large, and will not be able to inform us on the Fermi Paradox.
why is the relative abundance of elements in our galaxy, in our solar system, in our gas giants, and in our sun so consistent yet so different from the elements found on earth?

Hey jmg! What do you think of the ufo phenomenon that’s been going on recently? Is it political tensions regarding not wanting to seem incompetent, or is the lack of information about the objects speeds and dimensions conspiratorial perhaps? Idk just thought it was very weird
To be honest, I don't yet know what to think. We don't have a lot of information yet. But I'd tend to agree, it seems very likely that it's some espionage operation by China and or perhaps Russia followed by a questionable response. What will be telling is if in two weeks time we still haven't been told anything of substance.
John, sorry if I bother, but do you still plan to make a new video on Kardyshev scale just how you have mentioned not long ago?
It'll come up eventually.
@@JohnMichaelGodier thank you John. Big fan of your work.
I've often wondered about whether or not Earth is occasionally spawning new life here and there. I never thought about the possibility that the modern biosphere might not allow that to happen anymore.
Can you post these Videos on Spotify?
One more point if you will indulge me: I find it hard to imagine life growing up in fresh water as the dialectic charge resulting from the pumping of salt ions across cell membranes is literally the very fundament of the metabolism of all life on earth and most of the oldest and least changing enzymes common to all branches of the tree of life on earth are ion pumps suggesting to me the unlikelihood of anything earlier which now leaves no trace in the genetic structure of life to be suspiciously improbable. These ion pump enzymes are so fundamental not just because of their high invariance across the tree of life but also their forming the basis of so many other, often themselves highly fundamental, proteins and enzymes found across the ToL.
Who is the author of the painting in your thumbnail?
So from what I have seen in this and a few other videos?
-- There's apparently water/carbon based life that does metabolism with phosphorus, and then there's everything else, that has to do it with iron, arsenic, whatever else works.
-- And apparently, the water/carbon combination works out best for the relatively temperate and generalist-friendly conditions of Earth. If you're looking for carbon-silicon or silicon based life, you'll have to look up rarities in extreme environments, or places where heat, cold or acidity favor the different chemistry.
-- This would imply that as long as the metabolic chemistry is the same (phosphorus-driven or otherwise), then water/carbon life is going to largely be compatible with itself wherever you go, and that there MIGHT even be future medical technologies that would allow exotic iron-metabolism life to be made compatible with its phosphorus-driven counterpart.
-- Meaning we're way closer to _Star Trek_ convergence and commonality than we are to a "mutually poisonous" scenario where life exists but can never make direct contact with us, or us with them, due to the chemical differences from the Periodic Table. So, good for some mutual contact (eventually) but also bad if you consider that contact includes microbes and diseases.
Strange days indeed. Especially with our suddenly going from shooting Chinese surveillance balloons to shooting at . . .whatever those three things were. ;) Here's hoping we didn't ventilate our version of Kal-el. =))
"We are bags of salty water."
Makes sense we left from fresh water. More electrolytes? Connectivity for our brain usage. Plus warm blood.

@@JohnMichaelGodier Count me in as a customer if you do!
Fascinating 😊
It's interesting that assuming life developed on earth we dont see other independent examples of the process that we can study. It's seems like it happened once a long time ago and then those conditions have never been met again, or at least we have never found them. I wonder why that is? If earth is such a great place for life why don't we see more recent independent examples of life arising?
Honestly, the news, The Times we live in.
I think the necessity of salt in the evolution of life indicates why hardened arteries are so common throughout the galaxy.

It may be that several similar options appeared and then earth got free oxygen. That alone could have wiped out most contenders and prevented new ones.

Just because I dont comment doesn't mean I haven't been here for years and have been doing this for 32years I've been at this since I was 11
I don't like the story very much in 'songs of distant earth'. However the world-state Clarke creates is one of his best, as is the elegiac tone of his prose. In my opinion it is only bettered by 'Childhood's End' which I consider to be his best book. It is _also_ about evolution and the transition of life...
Ironically in 2010 super-Bowman makes only a trivial examination of Io, his interest primarily focussed the native life below Europa's surface and in the cloud-banks of Jupiter itself. Given what he does to the gas giant and the likely effect on the first moon that was probably wise!
Isn't it attempt no landing on Europa?
How did you resist the pun "saltwater is the solution that might be the solution to the Fermi paradox?"
