I love these ones with JMG it might be 15 mins long but I find I have to listen to it 2 3 times as it eases anxiety and of to sleep sometimes within 5 mins , you've a real gift to the community thanks again John and anyone helping behind the scenes these episodes really make my week ♥️😁
I love that I can have that effect. Seriously, that's very important to me. It makes my content valuable above and beyond science commentary. Sleep, relax, and escape from the anxiety and dream of what may be. And be well.
@@JohnMichaelGodier the fact you take the time out of what I'm sure is your busy schedule to interact with one of your fans just shows how much of a down to earth and caring person you truly are thanks again can't wait till thrusday for my next instalment wither it's exploring space with you and your guest or the history EPs which I really enjoyed a couple months back, keep up the amazing work! 😄
@@JohnMichaelGodier I love your videos for that! You have a very relaxing voice and im always fascinated by these subjects so it really does help relaxation.

God likes you.
ryan smyth - I can relate. JMG’s ‘Fermi Paradox’ playlist works better for me than ANY anti-anxiety medicine. If I fall asleep to it, then awake, it’s profound how at peace I feel 🥰
I totally buy into that solution of the Fermi paradox: that there is microbial life everywhere in the universe, but that the step up to intelligent, technological, space faring life is exceedingly unlikely and the time window with most stars is too short.
Seems like it would be amazing but anti-climactic at the same time: life starting is common in the universe (wow!) but life lasting and/or evolving to meaningful intelligence almost never happens (oh....). We're not technically 'alone', but it could seem like we might as well be....
the common rebuttal would be, that this earth still has a couple of hundreds of years left and life only took 400Mya to get from walking fish to talking apes. If humanity was snuffed out today it would probably not take another 400Mya for intelligent life to get on track again. There are decently intelligent animals with potential alive today that are not apes.
@@Eckendenker The point was that although microbial life showed up very early, multicellular life did not show up for a long time. In our case, it took more than half of the Earth's habitable lifetime before that happened. Once that happened, there was an explosion of complex life as evolution was able to diversify to fill all those available niches. If it is that much harder to progress from microbial life to multicellular life than for microbial life to arise, then multicellular life could be rare even if life is not.
Study estimates there may be up to 6 billion Earth-like planets in our galaxy. I find it hard to believe that a couple of those “earth like planets” don’t have intelligent and technological life on them. That being said this does not necessarily mean that any of those intelligent civilizations on other planets have made enough technological advancement to contact us. I also can’t help but speculate that there have been other civilizations on other planets outside of our galaxy that have perished from catastrophic elements and events.
Most stars have life spans of trillions of years, wtf are you talking about?
I have some strange obscure thoughts from when I was a kid and I love when John validates one of them from time to time .
Tell me that username is ironic
I love your username
Such a awesome channel and made me realize my love for all things space. Never stop making videos JMG
th-cam.com/video/JdHytrXVoQo/w-d-xo.html best video from John imo
🪶 🐍
What if he starts making antisemitic, holocaust-denying videos exclusively, like total hogwash? Should he never stop making those? What if he becomes some kind of leader-figure among white supremacists, gaining a huge and rapidly growing audience/fanbase through these videos? You still want him to continue churning out videos?
Jon I’ve watched all your videos for a long time now and I love all of them. Not only do they help sleep but I have found a new passion and curiosity with space and the origins of life. I hope you continue to make content for years to come. You and Sea are the two channels I always recommend for space content, your theories and interesting views on the universe mixed with the long documentary style videos that Sea creates just fascinating! and nobody does it quite like you two. Thank you Jon for being yourself and please know that you do have some really loyal subscribers including myself.
Thanks Jacob, and I'm not going anywhere. This is what I love and this is what I am. There is nothing I'd rather be doing.
Geo Girl recently did a video about water ice, illustrating that the ice we know - Ice 1h - might be rare. It's possible that life as we know it may depend on more than just liquid water, but the phases of ice that are possible on a given celestial body.
That clip of alien birds landing on a tree is driving me nuts. I know it's from a discovery documentary from pre/early HD television because I remember it every time I see it used. But for the life of me I can't remember what it was. It's personally lost media lol
.
Was it ancient aliens? I thought I remembered it from that. Maybe has been reused by discovery
Or reused by history channel
Yyyyyy
There's a documentary about an astronaut traveling to the far future that I've been looking for for years.
I'm guessing a lot of science documentaries are lost media
Been absolutely enthralled in these videos. Your way of explaining subjects and the angle you come from is so interesting... can safely say is one of the only channels that gets me properly thinking!
i suggest 'history of the universe', 'sea' and melodysheep, melodysheep i kid you not has the BEST space computer graphics i have ever scene and the music he uses is top tier, highly recommend it!!
Yea this one was pretty dark. Thanks for the reassuring fact that most likely we'll run into terminators instead of biological life. Really starts my morning off with existential dread. This is what I'm here for. Thank you for the upload Mr. Godier, exceptionally spine chilling.
Take heart in the fact that your own existence was so stupendously unlikely that you've already won the biggest lottery imaginable. Whatever happens to you from now on just adds or removes a couple decimal-9's from the probability.

I like that. "Are we alone? ...No, not always..."
Betteridge's Law of Headlines says, "No!"
But I will listen anyway - just because it's you, John.
Never been a fan of Betteridge's law. If it were 1935 and I wrote a newspaper article entitled "Will the Human Race addict itself to a handheld supercomputer that fits in the palm that everyone obsessively checks multiple times a day in less than 100 years?" no one would have published it and the answer was yes, it's the smart phones. I actually collect headlines that violate that so called law. My favorite is from 1904, and in a nutshell it's a criticism that Mr. Carrier's Cold Air machine will never have a practical use, and was hype. It's now known as the air conditioner. You can play with all sorts of violations of it. Write a headline in 1950 that says "Will we be on the moon in 20 years?". We were. In 1780 you could sensationally ask "Can we Preserve Food in Vessels for four years and eat it?" Yes, it's called shelf-stable food canning. Or 1789, "Can we blow up a Japanese city with the rock Klaproth recently found?". Yes, in 1945. Not really sure why putting a question mark at the end of a sentence became some kind of law.
Look forward to your vids. Keep it up! Love them!
Best part of any day is discovering you’ve posted a new video! Amazing work
Just discovered your channel, currently binging your content! Keep it up, sir, very good stuff here.
It's important to remember that there isn't a clearly defined boundary between chemical reactions and self-sustaining life. Even nowadays it's entirely feasible to watch microbes gorge themselves until they drown in their own filth; it happens every day in countless petri dishes around the world. I 100% support the idea that a plausible solution to the Fermi Paradox is that life rarely manages to become widely-varied enough fast enough to start regenerating the environment as fast as it burns through the available resources. Hell, we're doing that again right now.
It seems that spooky October goes on and on forever. Thank you for another great video, kalimera from Greece, currently happy that you have included references to greek mythology into this interesting subject.
Always in bed, drifting away to your chilled narration.
I was just looking back in all your video’s, hoping I forgot to see one. Just to have a new one to listen and watch. But nope didn’t miss any of your videos. Thanks for the good work. 👍😄
Just realized I always click "like" at the beginning of each JMG video instead of waiting for the middle or end.
Great segment, keep these coming John. Love to just sit back close my eyes and and take all this in that you provide
I love your videos and all the possibilities! Thank you JMG, please continue to expand our possibilities.
I’m Martian and I’m right here. I have dual citizenship.
Do Martians tax expats?
Tay, do you come in piece? Or whole?
This is like seeing Bryan Cranston buying milk at the grocery store.
I knew it.
You have a duel personality problem. There are no more martians. They died out completely 500 million years ago. The last of they're technology sleeps deep beneath the Antarctic ice sheet called the Oberon Module. 👽
This makes me think of the giant Crystal Cave. A horrible generic name I know. It was completely sealed off, it had its own atmosphere which was extremely deadly to us humans but there's a whole range of Critters living down there. Not microbes but actual Critters.
Then think about how long it took us to find it. We humans has been digging and Drilling and leveling entire mountains at times, looking for a resources. This cave was a fairly new discovery.
I absolutely love your videos! Keep up the good work :)
always a nice night when john posts a vid
My favorite night time channel when I'm unwinding, trying to get ready to sleep.
you never disappoint John. a great video and a great concept as always
true tho
It's good having you back!
How would the Great Oxygenation event look if it happened on Mars? Is it reasonable to think it would have happened over a shorter timespan, and would shorten the timer for aerobic life to evolve and stabilize the environment?
I really dislike having a biosphere sample size of 1.
Another fantastic video, John! Thanks!!! 😃
Stay safe there with your family! 🖖😊
Greetings to you John Michael... I've just had your video with a cup of coffee.. Absolutely stunning as always! Thank you from Cape Town South Africa 😎🌻🇿🇦
Always good to see John upload
Glad to hear your voice again!
Great way to start my Tuesday. Thanks for the video.
I happened to be looking up sand dunes and saw a picture of Dune 7: Namib Desert, Namibia. I wanted to read about it so I reached over to pause your vid, Michael. I paused it at 5:38 and it is breathtaking how similar Dune 7's structure looks to the deposits shown on your Mars image.
Hey John, long time fan. I just want to thank you for some beautiful sound quality in your videos. Dunno if it's you or a team or what. Either way, your voice sounds great and the sound quality is very consistent across videos.
Content's always been on point but it's SO nice to put your channel on to fall asleep to. It really helps when the volume isn't peaking all over the place, I can focus on what you're saying instead of constantly fiddling with the volume button.
That's audio normalization, it takes the recording as a whole and smooths out the volume overall to prevent peaks and retain consistency. I use the same settings for all videos. Event Horizon has a team, but on this channel it's still just me. Other than researching and writing the script, the audio editing takes the longest for a video. Luckily, I used to be a musician, so I already knew the process for polishing up audio and was able to adapt it for spoken word. The strange thing is that the sleepy effect also works on me. I can edit the raw audio no problem, it's just me talking, but the moment I bed the music these tracks take on a life of their own and become JMG videos. As a result, I'm ready for a nap after my final listen through, as though it wasn't me that just recorded it. Very odd trance-like effect. Works on Event Horizon as well, I often have very little recollection of conducting those interviews, as though I go on some kind of autopilot. And I can then go back and listen to those interviews without ever consciously realizing it's me hosting. Pretty weird, but that's how it works.
Usually youtube does not notify me about your new videos. But for some strange alignment of the planets, it did today, and now, it's a better day.
Good Stuffffff Bro, can't wait for more, I liked and dinged the bells, all of them
That was very well done and thought provoking.
Anyway, so long and thanks for all the fish.
Hi John
Here’s a few ideas you never hear alien theorists talk about.
What if aliens are microscopic and are in fact the ship itself rather than travelling space in a disc.
We anthropromorphosise thinking they would look like us and be in a metal craft but it’s very earthling way of thinking
What if we are microscopic aswell? Have u imagine that too?
Thank you for this wonderful video I've learned so much from your Channel I'm now taking up astronomy as a hobby
I really need to rewatch all these instead of listening to them. Ok and also picking a playlist and falling asleep to them too XD. The visuals are great.
Perfect timing, again!! 😁
Great vid. Really puts into perspective how important RNG is for an intelligent species to develop.
In which we liiiiiiiiiiive. Thanks mate, you make life here on earth here a lot easier to handle by posting.
Very nice, and I appreciate the darkness. 🙂
Thanks for th'introduction to the Medea hypothesis.
Typically awesome video! Thank you JMG! At about 13:00 in the video you mention one aspect of the habitability of a planet as being its size. There's a condition of Tsiolkovsky's rocket equation that describes an upper limit of a planet's mass versus radius where chemical propulsion is impossible, due to the sum of propellant mass and payload to achieve escape velocity. There could be habitable worlds featuring intelligence that cannot achieve escape velocity using our path of chemical propulsion. Scientists have proposed that the solution would be to build vast aerial platforms to raise a reasonably gigantic rocket to achieve orbit. Of course, there is always the nuclear solution.
Indeed, the rocket equation limits chemical rockets to about 1.5 earth masses. But it's thought habitability goes all the way up to two earth masses. There's always nuclear as you say, but that may suffer a different problem. More massive worlds may have more rare nuclear resources, less uranium at the surface etc. It really is an uphill battle for worlds larger than earth and it wouldn't be surprising if there are locked in civilizations on larger worlds.
What music/songs are used in the background of the videos?
I often wonder how people who don't wait on John's uploaded with held breath and just stumble upon a video react to the ever growing length of 'universe in which we liiiiiiiivvvvvvveeeee'.
Your videos are the favorite part of my daily routine. I get the notification on my phone on nights like this and think to myself today's a good day
I've always thought it possible for all of humanity's stories of the "Battle of Evermore", the Yin/Yang, the Good vs. Evil, all of these might be referencing the two worlds of Earth and Mars.
John, one thing you may not have talked about is balloon type habitats floating high in Venus's atmosphere... They would have adiquate gravity along with lots of gasses, chemicals to make what you need... and the temps are Earthlike at altitude...
Plant life on land didn't develop until the Earth's magnetic field reached sufficient strength, I think this is when the inner core fully formed. Until land plants form its very difficult to envision any kind of animal life evolving on land. This may also be a great filter that explains why on a planet did life evolve so quickly yet took so long for sentient land life to develop to a point where it could put a tesla into solar orbit.
Great stuff!
Thanks for the upload
Love this channel ❤️

fantastic episode :D
Nice overview
Greta video as always
It's always a good day when JMG posts
Hi micheal what do you think about the earth core not rotating anymore
This reminded me of what happened to life down in Antarctica. As the continent moved to the south, and S.America and Australia separated from it, so the ocean currents swirling around Antarctica had an unimpeded path. This cut off global ocean currents bringing warmth to it, and without warmth, the continent froze. Coupled with global temperature changes, in a span of a few million years, flora and fauna had to adapt from temperatures similar to today to way below freezing. Remember, life was trapped with no way to escape to the other continents. And so entire ecosystems simply froze to death, unable to evolve to survive the cold and dark conditions. Sure, you have still Antarctic Moss and Penguins, but the extinction rate was punishing. It must have been a slow, bleak outlook for those organisms. And even though they didn't cause the great freezing, Antarctic life was lost to time anyway. Did this happen to Mars, and could this happen to Earth? In the vast scales of time, it is anyone's guess.
Main Video: So it looks like there ought to be math to apply here. Perhaps you plug some numbers (modal planetary temperature, modal planetary pH, water content, magnetic field strength, etc.) into a *Statistical Extinction Equation.* Most of the time you get a Medea world (self-destructive) but occasionally the world reverts to the *median* versus the mean (average) or mode (most common). Meaning if a planet dwells in the middle numbers long enough, then you get a Gaian world. But that's the catch: statistics don't usually hang out in the middle that way. That's why you get to avoid calling it the Life Equation--which is good for lawsuit prevention. ;)
Ending: And I don't bring up Tabby Boyajian's Star all that much either, for precisely that reason. =)) IF the superficial appearance of rampaging Dyson Swarming around line-of-sight stars in the parsecs around Boyajian's Star are what they seem to be, and not just magic weirdo DuUuUUUUuuustt, then it would seem OUR star could be on someone's list. I Do NOT Like To Think Like That. (please pardon the Southern Caps, but I don't want to completely scream that) If I have to dote upon stars with possible wayward life, I'd rather stick to flagrant necro-signatures and/or star systems so young they barely have planets, never mind life. Meaning: Easy Mode. =)) Because there's nothing I could do--hell, nothing anyone including the late Stephen Hawking could do--about a mid-stage Diamond Age bunch of exo-technological-persons like what could be snarfing up Boyajian's Star. If they showed up here they could just TAKE our sun from us, ignore us entirely, and there would be less than nothing we could possibly do.
Love topics like this
I am pretty shocked one of those rovers has not seen something definitive
It very well could have, and has been scrubbed to control the narrative. As slim as that chance is, it is still possible.
Aside from ruined buildings/tech or dead aliens, what would you consider definitive that could be seen?
I'm still waiting for the notification.
Do you have audio books?
Good video.
Mars potentially having had life at some point is terrifying but Mars never having life would be just as scary. Same with Venus if we can ever explore there to find out. Having had life and then losing it shows just how on the razors tip of habitability we really were and still are. Same if both of them turned out to have always been dead planets. If Earth were the only planet to have developed life let alone advanced life in a solar system with 3 planets with water in the habitable zone then those are lottery odds against developing life.
All traces of any life on Venus are likely to have been erased by the extreme heating of the surface and geological activity.
Mars may have had simple unicellular level life very early in its history. We may be able to find microfossils.
But it's obviously that they are lottery odds against developing life even if you have water and are in the habitable zone, if life were that easy we would have already find life or we would have been colonized
That went so dark at the end. And I am here for it.
Looking at the dark “streaks” in the crater at 8:40, one can assume that the same shadow shown on left side would appear on the opposite side at a different time of day. Given the huge temp fluctuations Mars is know to have from light to dark, could it be likely that said streaks form from condensation that forms on particular rocks during temp changes and the small amount of gravity pulls the liquid towards the base of the crater? Depending on the amount of moisture in the tiny atmosphere of course.
Recently saw a documentary on curiosity stream regarding new discoveries in the field of underground life. Especially chemosynthethic life seems to be basically everywhere it can be so it is reasonable to assume that there is a layer of microscopic life going down somewhere around 10 km below the surface basically everywhere(varying on local geography of course).
That being the cas I find it hard to believe that if Mars ever had life some vestiges of it don't stick around in a similar manner below the surface.
happy Lunar New Year
Totally off topic but just wondering if you ever read much Clark Ashton Smith, John?
John, great video as always. I'd be curious to know if you personally think Mars is worth investing in (such as building bases or even terraforming one day), or do you think we should invest elsewhere like focusing on other parts of space to explore?
I support missions to Mars of course, but I'd tend to favor building fully self-sufficient O'Neill cylinders as far as colonies go, but there's also the upper atmosphere of Venus that's interesting since it's actually more earth-like than anywhere in the solar system.
would be better to focus on the earth from now, humans might not even be alive when the sun expands! we'll get to terraforming mars and possibly venus once we've managed to save our own planet first, for the next few hundred years mars will be best left as scientific study and nothing else.
@@JohnMichaelGodier The scary thing about floating structures in Venus's or a gas giant's atmosphere is losing buoyancy or lift. What contingencies can there be if something goes wrong?
Mr pibb is better, however I don't want war. I simply want choice. Good question though
@@JohnMichaelGodier Good point. I wasn't even thinking about Venus until you said it. A future Europa mission will be interesting to see as well.
Mars still has a liquid core and more magnetic field than previously thought, but still not enough for humans.
Love you john!!!
I think that "intelligent" life on earth is currently "self-destructing".
Possibly the darker video of this channel. Really cool paradigm
Excellent channel
There is a lot of this Martian history which is highly dependent on the assumptions used to interpret the limited data we have. For example some work indicates most evidence of water on Mars has characteristics which best match subglacial flows which could mean Mars never had a substantial atmosphere being an ice shell world instead punctuated by violent transient flows largely localized to volcanic regions.
We really need more data, however with the little seismic data we got from Insight before it died to Martian dust showing a larger less dense core which if the majority of the lower density material is hydrogen as seems likely then that could naturally have self terminated the Martian dynamo before it could even begin.
In regards to the time life requires there are some interesting correlations between thermodynamic modeling and limited geologic data which suggest the late start of complex life as we know it may have been thermodynamically constrained. In particular this has to do with the faint sun paradox and the evidence that little if any land existed on Early Earth. It has been noted that the hydration of rock is a process which is thermodynamically constrained as in heat inhibits this reaction keeping water separate from silicates which given that Earth's water budget and isotope ratios appear fully consistent with its total silicate mass. Given the increasingly violent nature of models for the proto-Earth Theia collision to form the Earth Moon system it seems probable that these fluids likely coalesced rapidly along with their rockier counterpart minerals in the two molten worlds with the pressures and temperatures likely being extreme enough to result in the fluid being at least partly supercritical ergo oceans from the start before the crust can even solidify, moreover these would likely have been massive deep oceans far deeper than modern oceans as they were both hotter and contained much if not most of the water now locked in mineral hydrates within Earth's mantle so at the minimum 4 times the water of our oceans so more than enough to drown the early continents far beneath the surface. The planet would however cool so barring the bombardments and emergence of life which happened around this time the planet would start cooling down thus allowing more water to combine with silicate minerals to form hydrated minerals(clays and the likes). This would gradually cause ocean depths to drop as the planet cooled.
Based on some simulations of this process it is interesting that the emergence of continents into sunlit depths happens to coincide with a major event in Earth's history the great oxygenation event, this seems bizzare unless you have been reading up on the latest work studying anaerobic metabolisms of Earth which have identified the inherent poor evolutionary fitness of aerobic photosynthesis the extraction of molecular hydrogen for carbon fixation using water as the hydrogen source. This has to do with our good friend quantum mechanics as it turns out oxygen has one of the highest electronegativities of all elements with only Helium & Neon ions or Fluorine surpassing it. In terms of chemistry this means that it takes a lot more energy to split hydrogen atoms with their electrons intact from the oxygen atoms thus there are very few energy sources which can do this with water compared to other sources of hydrogen ranging from plain molecular hydrogen at geothermal vents, hydrogen sulfide or dissolved ions using dissolved ions as electron donors for fixing carbon. Anaerobic sources will thus naturally be able to utilize resources at deeper depths thus depleting them and preventing oxygen from taking over so long as you have resource constrained conditions where mineral resources primarily diffuse from the seafloor into the water column.
Once sunlight can reach the seafloor this bottleneck goes away as aerobic photosynthesis can compete with other carbon fixation pathways thus oxygen levels can rise, but only so far. Thus you can explain the first Great Oxygenation Event and why oxygen levels bottomed out as the oceans stayed anaerobic for the next 1+ billion years with aerobic life restricted to the shallow waters of the continents. We can actually see evidence for this hypothesis based on the phylogenetics of aerobic bacteria and metagenomics of Asgard archaea showing that Eukaryotes closest relatives are all found in shallow largely freshwater environments with the oldest known aerobic organisms in the oceans to coming about until the late Neoproterozoic.
The mineral hydration can explain that second spike too since that appears to be when the mantle cools enough to support lower density hydrated minerals which are capable of accumulating beneath subducted slabs to form buoyant thermochemical plumes highly enriched in accumulated sediments dragged into the mantle with subducted slabs. Just the sort of drastic influx of volcanic fertilizers during the formation of a new interior ocean within a rifting supercontinent to help aerobic life colonize and compete with anaerobic life to high enough concentrations to poison anaerobic primary production.
Notably this process also helps answer one of the major questions of why and how plate tectonics has gotten deeper and faster over geological time since the layer where the critical mantle hydration occurs at descends deeper into the planet as it cools and the chemical process can naturally release the energy needed to power such a dynamic process.
The interesting thing with this model is it suggests life on Earth advanced in complexity within a few million years of when it became thermodynamically possible to do so. If this thermodynamic argument can be generalized you may be able to calculate the expected timescale needed for complex life on a world of a given size and as a consequence of the square cube relationship between volume and surface area its a nonlinear relationship with the hydration process occurring far more rapidly in lower mass planets. Its very well possible if not probable that Mars underwent a similar cycle early in its history likely on the order of a few hundred million years I wonder is that enogh for complex life to make the jump? Could there be a minimum threshold?
I'm a simple man, I see you upload a video I click
The French Sci Fi drama " Missions " explores this. It's on BBC iPlayer for UK viewers.
What was the name of that movie about this? The one where they go to mars, they enter the Mars Face and its an alien artifact and it plays all this. Spot on!
It was a Disney movie called MISSION TO MARS, it starred Gary Sinise. Around the same time another movie also came out called RED PLANET starring Val Kilmer.
Another winner!
Good stuff
Your statement about "stability and abundance " as a factor in the persistence of life on Earth got me thinking. Even abiotic and inorganic chemistry requires some instability to initiate and accumulate. A bit of turbulence and temperature variations in a heterogeneous solution with varying concentrations of the appropriate molecules makes abiogenesis possible, however improbable. A microbial world with too much stability cannot compel, convince, coerce or inspire microbes to mutate and diversify beyond a narrow monoculture that ultimately consumes its resources and drowns in their own poop ( where overabundance creates the mechanism of its own extinction. ) So, stability and abundance are both necessary but insufficient for the persistence of life. Diversity is the other key factor. Diversity of forms that thrive in a variety of environments require the proper amount of stability and abundance to emerge over time, and contribute significantly to the persistence and resilience, hence the abundance and stability of the biosphere as a whole, even as individual species arise and die off relatively rapidly. Fascinating post. Thanque for the inspiration! 😃
Interesting post. If you are curious about this, I would definitely recommend that you check out what nasa is doing with their rovers. They are going to mars and looking for life and other things in the sand. If anyone knew whether life would self destruct there it would be them now. Check it out.
I was wondering if you could do a video on what humans would do in relation to zoo hypothesis if we were the aliens.
Like ... if we found a Neanderthal level civilization do you think we would contact them? Uplift them? Just watch? Interfere if the eventually evolved technology and were about to go nuclear?
Given humanity's history if they have anything of value they won't last long once we're aware of it.
The more one studies the geometry and the astronomical correlations of the structures in Cydonia, the harder it is to dismiss it all as chance.
Is it possible the terrain itself contributed mars loss of atmosphere? with high enough winds and Mons Olympus caused enough uplift to slowly drain the atmosphere off into space?
I think the current theory is a decrease of magnetic field from the Martian core lets solar wind scour the atmosphere, blowing it off. Depending on how the weather works, Mons Olympus could be a spot where more than usual gets syphoned off, but personally I think the difference that terrain makes would be small, especially compared to the effects variations in the remaining magnetic field might have.
I'm not a meteorologist or an astronomer though, so take my theory with a pinch of salt.
So fascinating
I love the self-awareness, going full doomsday-esque great silence, but then topping it off with the notion that maybe a past civilization made von neumann probes and they'll fill up that emptiness just fine.
Not sure if that's even more bleak than the great silence or if that's fully solving the great silence, but that's great writing indeed.

After seeing you comment about the upper atmosphere of Venus being more earth like than anywhere else In the solar system im really intrigued
It's true. There is a layer in Venus' upper atmosphere that has both similar pressure and similar temperature to Earth. It's one of the few places in the solar system where if you accidentally had a rip in your space suit, you could take your time getting back to your habitat, no big deal. You couldn't breathe there, but in some ways it would actually be safer in that environment than very deep sea diving is here on earth. What's also interesting is that Venus' lower atmosphere is so dense it would be easy to float a habitat in its upper atmosphere. Here' a NASA concept on that for further reading, Cheers!:

@@JohnMichaelGodier thanks man! I had no idea of this concept this is awesome
Thank you
Someone left the front door open and all of the atmosphere escaped. When your dad tells you to close the door because you're letting the air out, he's not kidding!
Interesting to see Human intelligence through the prisms of the Gaia and Medea hypotheses. Which will be ultimately choose ? To self regulate or to extinct ourselves ? The fact our mythology came up with both suggests the human collective unconscious knows it is a live question. Great video.
Ahhh happy thoughts!
I love the thought that there might have been two, if not three abiogenesis events in our solar system. “third time lucky” ! 🌍 🤓💚♾️
If you ascribe to the Earth zoo hypothesis, then it's just as easy to ascribe to the idea that aliens may have moved genetic material from Mars to Earth to watch it develop further. That would make us the results of an evolutionary experiment.
