If astronomers confirm that there is a gas giant orbiting Alpha Centauri, I hope they name it Polyphemus.
why would they name it after a cyclops shepherd?
@Birbology ! Good point. If they find evidence that it once had a "Great Spot" - type cyclone (and only one such storm), but no longer does, then it might be a fun reference to the Odyssey (since Odysseus gouged out his only eye in self-defense). Of course by the time we get information *that* precise on the planet, we likely would've named it long ago.
😂😂😂😂❤
Don't bet. They didn't respect Bellerophon nor Osiris. The names given for the discoverers to the first extrasolar planets.
There should be international law, that if a science fiction work predict some phenomenon, and it is later discovered to be real, then it has to be named after that scifi.
If you have unobtanium, sure.
The problem with unobtainum is that as soon as you get some, it becomes obtainedit.
it becomes gotsomeonium
@@thearmchairspacemanOG 😂😂😂😂😂😂😂😂😂
In theory it would also allow you to build a craft capable of drilling to the Earth's molten iron core to deposit several nuclear bombs in case our dynamo ever shut down.
@@AceSpadeThePikachu i got the reference
“Obtainedium”
Cameron has already revealed the main antagonist of the next film will be a fire tribe of na'vi similar to how there were water tribes in the latest film. If Pandora is tidally locked I'm fascinated by a possibility that there could be a "twilight" tribe that lives in this eternal darkness. A cinematic challenge no doubt
Fire tribe? You aren't referring to other "Avatar"franchise, are you
Twilight*
@@rosyidharyadi7871 nope, Cameron has said that there will be a fire nation called the "ash people," and they'll be much less friendly than the water na'vi, probably playing a villain role in some capacity
I hate to crush your hopes, but I think if it was tidally locked, it would be permanently facing the planet, not the star, so there would still be day and night time. But, depending on the axial tilt of both the moon and the planet, there could be some sort of twilight on the polar regions of the moon? Sort of like an eternal sunset?
There's still a day and night on the moon, it's just that one side always sees the gas giant and the other side never does.
I lived in Alaska for 23 years, and one of the best auroras I've ever witnessed had green, blue, violet, red, and white in it. And it really danced (meaning it moved and jumped around quickly. Some auroras just slowly drift by.) We even caught this on camera. Absolutely breathtaking.
I lived in Toronto most my life, I moved 5 hrs east of Thunder bay 3 years ago. Seen about 5 Auroras so far but with no color, all were white and could be mistaken for clouds if the weren't so bright
I could watch hours of just fictional documentaries set on pandora. The human conflict is something i oersonally would cut in favor of telling Navi Stories.
Yeah I second this, like I don't care for a story on human greed and war and conflict or anything, just show me the wonders and marvels of all the amazing animals and plants and different Na'vi groups on Pandora, please! Like we need a tv series of documentaries on just the Na'vi and the fauna and flora!
@@Manj_J cringe
really? you dont realize its just the same old stories with blue aliens?
I've never seen an Avatar movie. My religion forbids watching movies with blue, sentient creatures. J/K. Seriously though, many people have gotten 'spoiled' from seeing the beauty of a fictional world, and can't appreciate the real beauty of our amazing world. So, I'm not sorry that I didn't watch them. I probably will eventually.
I haven't seen the new movie, but I loved the old movie as a kid. There's something about dystopian but still futuristic human culture that grips me, even if it's mostly American culture.
It gets me moreso when there's interaction between two communities like that, first contact stories (and first contact by us, done wrong) fascinate me to no end because I loved coming up with ideas on how it could've been handled better and more peaceably.
And I didn't even get to mentioning cool mechs or crazy VTOL craft juxtaposed with natives, they're so deeply detailed and I think it's because that's how the Navi would see them too. You'd have to be searching for weak points or things you can exploit so you kind of have to be looking for detail.
These avatar movies are different than just normal movies imo, they are more an experience and an escape from everything and i absolutely love them, especially at the cinema. Can't wait for the future avatar movies.
yeah they’re visual experiences because the world is just pretty but poorly built and the story is bland, very very bland
Explains why we will never get enough of these idiotic bland empty spectacles.
@@pabloalonso9162 "poorly built" - I assume you didn't watch the video?
Now that I've watched the whole video, I'm glad you touched on the aurora. That would be an indicator that Pandora has a magnetic field. Given that it is rich in superconducting minerals, this would only serve to enhance the magnetosphere of the planet. It makes sense that it would have one powerful enough to protect from the radiation belt.
The Mother of all Mag fields! That close to a gas giant, it would fry.
In China, Avatar 2 was surpassed by a local Chinese sci-fi epic called The Wandering Earth 2. I find it quite curious that both films deal with Alpha Centauri as the main target for human survival, and reflect on the limits of today's technology.
Is Alpha centauri really is humanity last survival?
@CosmoTube well yea I guess humans could go to other planets and reach destination to alpha centauri
@@CosmoTube-ox1ep Actually no! Solar sails can accelerate a spacecraft to a fair fraction of the speed of light!
Chinese are just good at copying Americans ideas and inventions.
@@CosmoTube-ox1ep
That sounds epic
Next tackle How Realistic Is the World of Three Body Problem by Liu Cixin
If Pandora had a very short orbital period around Polyphemus, then it would be deep in the radiation belt. Better if it's more like Callisto's distance from Jupiter. But what sci-fi maker can resist close-ups of a gas giant? Cameron deserves a medal for restraint in not giving Polyphemus unrealistic rings.
I think of the floating mountains like the giant wave in Interstellar - a scientifically implausible liberty taken because it's awesome in a movie that otherwise tries to ground itself in the possible. Ditto the giant tree.
Came here to say just this and saw your comment. Anything that close to a gas giant, the amount of radiation bombarding that surface, I highly doubt anything could survive let alone flourish.
@@erdrickcapet3945 Yes, to live around a gas giant, you'd probably need far enough away from it for it not to look spectacular in the night sky. A shame, perhaps.
Gas giants also have dangerously powerful magnetic fields.
Based on the changing position of Polyhemus in the sky during both movies, Pandora is not tidaly locked. Sometimes we see it high in the sky, sometimes just touching the horizon, and a few times intersecting it.
But are those in shots taken from (approximately) the same location on the surface?
I really love the point you brought up about tribes on one side not even knowing they orbit a gas giant.
Cartoons need there planets ship fleets? Try designing one in children cartons! The company pland was cooked about maintaining Pandora? Keep useing if on let's see who needs it more!

@@sysomphonemanuthong3953 I think your phone managed to do a pocket response to à CZcams comment, that was basically unintelligible nonsense.
I think unobtainable is the most interesting thing about this franchise. It’s a superconductor that has a magnetic field which is not what we observe in reality. Such a sci-fi metal would allow us to make extremely powerful and controlled magnetic fields. So yes the mountains do act as a sort of magnet probably being drawn to Polyphemus’ magnetic field until it gets to an altitude where gravity takes over so you get various mountains floating at various altitudes.
I would love a video about The Expanse. Imho it is a very possible future - at least the technology and the story of colonizing on mars and the belt.
Yes, The Expanse!
Damn that was a good show, I might rewatch that again thanks
sadly it's on indefinite hiatus since s6 :(
@@alveolate I guess bright side is you got a chance to watch other shows 🤷♂️
The Expanse isn't "very possible", in its general contours it's the future. There will be space mining for the simple reason that (eventually) it will cost less to mine iridium and other high-value elements in the asteroid belt than on Earth. Mining creates settlements, as we've seen over millennia of human history. Settlements bring society, which spawns other industries. Now you've got a space economy. Putting aside the drama and liberties taken with scientific details, The Expanse nailed our future.
I would like to see the science of a plant based neural link to animals and restoring consciousness via its connections too. Supposedly there was an intense battle scene he cut from the movie because of current world events and violence but I bet it was stellar, hope its in the extended cut.
I'm a sucker for speculative biology so Pandora's ecosystem with the lands and creatures is what hooked me in the first place.
One interesting issue regarding a tidally locked moon (which would be almost all moons in most star systems) would be that there would be a higher prevalence of the night and twilight compared to light day. This is not necessarily a bad thing, on the contrary: The gas giant would shelter and act as a shield, diminishing the amount of harmful radiation that could reach from the star. Also, as the star development during millions of years increases the amount of radiation and heat, the moon would be able to adapt much easily than a planet to such changing conditions, thus protecting life.
The radiation from the planet is the biggest problem for life. If unobtanium is a superconductor, though, its occurrence on Pandora could mean a far bigger magnetosphere than a moon would generally have.
@@nagillim7915 Bioluminescence can protect against radiation and flares from an M class star. There's a lot published about it.
Wouldn't the higher prevalence of night time compared to day (at least on the side facing the gas giant) create a runaway cooling effect? If there's more night than day, then wouldn't it cool down more than the day can heat it up, essentially covering the facing-side of the moon in ice?
I was thinking of this while watching and trying to imagine a reason why this *wouldn't* happen, but couldn't think of one.
@@foosic1742 - depending on the size of the gas giant it might be giving off large amounts of infrared generated by its own gravitational contraction. That could heat the side of the moon facing the planet. And that's assuming the moon is tidally locked, which will largely depend on its distance from the gas giant and their relative masses.
If the moon is tidally locked then its day/night cycle will be determined by its orbit around the planet and not its own rotation around its axis. The length of that day/night cycle as well as the diameter of the moon and the thickness of the atmosphere will largely determine the climate. If Pandora is less than half the size of Earth then you'd need to half the length of the day/night cycle to about 12 hours to keep an atmospheric circulation pattern like Earth's: the coriolis effect has to be high enough to form Hadley cells in the tropics and a polar front or else atmospheric circulation collapses down to a single cell per hemisphere, meaning equatorial jungles, icy polar deserts and nothing but cool semi-arid scrub and savannah between the two. There'd be no jetstream, no temperate rain bands, no deciduous or taiga forests, no bread baskets of civilisation.
@wildfirex666 Who's in the what now? Is that a sarcastic joke? If not, what the hell are you on about?
I add to the floating mountains as a possibility that they AREN'T non-living chunks of rock in the air, but a living organism that has other tiny organisms controlling it entirely similar to coral, they create billions of air sacs that help keep the organism afloat, and the surface of the organism looks like rock because of it's peculiar armor that it uses for defense and camoflauge. I speculate these organisms are preyed on by flying creatures that favor the tiny organisms that create the air sacs, and to protect themselves, they'll sometimes lower themselves down to the surface so that they can blend in with the mountainous regions they hail from.
I've wondered about the factor of the Roche limit. A body of given size/density, if located within the Roche limit of the parent body it orbits, will be torn apart by tidal stress. This is the cause of Saturn's ring system. Visually it seems possible that Pandora might be too close to remain intact.
There isn't enough surface area on the top of the floating mountains to collect enough rain to feed the waterfalls.
Best explanation i have is condensation. Water evaporated from the planet surface condense in the lower pressure and clings to the surface of the floating mountains, creating runoff
I'm just a major fan of anything bioluminescence, which made me fall in love with the world of Pandora very quickly . I just wonder how likely it is for planets dominated with bioluminescent life to exist out there.
I mean certain parts of our ocean fit that description. I suppose the question is how likely it is that the surface and atmoshere of a planet would be dominated by bioluminescent life.
@@jeffbenton6183 Yes. This is what I mean. Just imagine walking through a bioluminescent version of Central Park in Manhattan. Or perhaps how we can possibly use bioluminescent plants and life to our advantage such as a replacement for streetlights.
@@jacksonbarkerthebluehairedfox I think in india we have forest of bioluminescent actually there are some mushrooms, Herb's and plants which glow in dark in monsoon ( rainy season) it glows more you can visit it
The question is what bioluminescence does for life on Pandora?
Like flowers are bright to attract pollinators while fruit is bright to get animals to eat it and defecate the seeds out elsewhere. Seeing the abundance of bioluminescence in plant life on Pandora might be wanting to imply a similar function... BUT why is this actually better then just simple bright colors seen in daylight? Answer: it very probably is not because maintaining that pretty glow (well beyond anything you see here on earth) all night ends up needing too many resources for any extra attraction factor. They'd be out competed.
You could still force a confirmation bias with more explanation, like maybe Pandoran animals can't detect regular colors well enough, but we know this isn't true of the Na'vi so why not others?
@@blacksage2375 The answer is simple: there is so much bioluminescence and only tammed eclipse "night" because it's a movie searching to be visually appealing. An horror film like Pitch Black did the absolute opposite choice to serve the scenario.
There is no point to search scientific explanations inside that Pocahontas rip-off blockbuster series. It's really not that deep in every level.
As a Communications Engineering graduate, I found this video extremely interesting. The technology itself was astounding and the explanations were outstanding. Such videos would have been very helpful in my student life.
What about tides on Pandora??? Since, according to your video, Pandora is not tidally locked with its home planet, and since the home planet is MUCH larger (and presumably more massive) than Pandora itself, then the tidal effects of the home planet on Pandora's oceans would be ENORMOUS. On Earth, with a relatively small single moon, we experience tides that can often range from 10-20 feet, depending on the local geography. On Pandora, the tides would be immensely bigger. This would have major consequences for any areas near a Pandoran ocean.
I love Avatar but had no idea it was based in the Alpha star system. Thats awesome
When I heard that I was surprised too. I had no idea it literally takes place in our back yard. Our closes start system.
@@-TheMaskedMan- it’s literally a film
@@justsean6199 It is??? I was really hoping to visit the Navi sometime 2040😔🙄
Floating mountains are probably unlikely as depicted in the film. Perhaps if there are some magnetic forces involved, maybe combined with gravitational effects of the gas giant the moon orbits (so floating mountains would only be on the side facing Polyphemus?), and toss in a thick enough atmosphere and make the mountains out of material that's relatively low mass to boost their buoyancy. Like Alex mentions in this video, I agree that the waterfalls just wouldn't happen - aside from where all that water is coming from, would whatever forces that allow the floating land allow for the water to fall instead of just float away?
If the magnetic forces were enough to lift rocks, unobtainium or not, they’d practically rip the iron right out of living creatures’ bloodstreams.
I LOVE your videos!!! Not just narration, you provide opinions, and delve deep. Providing extra content like this just adds to the interest.
THANK YOU!
It has floating mountains, so I'd say that scientific accuracy wasn't a priority?
Everything that are innacurate on Earth science doesn't always the same on another planet
James Cameron pours an incredible amount of research into his projects, so I'm not shocked that life imitates art. Conversely, as we see with the Halleluja Mountains, he's also able to suspend disbelief in order to give license to artistic creativity. Personally, after watching the second film I can honestly say that the Avatar franchise is probably right up there next to Alien & Predator as the best xenos-based series of all time.
He messes up big in _Avatar 2_ in that humans apparently have the technology for interstellar travel but can't build space habitats like O'Neill cylinders. Building a space habitat is a far simpler engineering and technological task than interstellar travel.
@@primmakinsofis614 Devil's advocate counterpoint is that technology doesn't progress in a purely linear fashion. We could have a monumental breakthrough in space-time manipulation before we figure out all the engineering & logistical aspects of making a space habitat. That said, I do find it highly suspect that they'd actually struggle as much as they do on the planet itself. Being from a higher gravity planet should give Humans an insane physical advantage over native wildlife, including the tribesmen, regardless of their size. Humans having the same physical capabilities as they do on Earth always struck me as a bit annoying, although these are gripes I moreso had with the first film. Still, wish Cameron poured as much effort into astronomy & physics as he did into marine biology & ecology.
@@primmakinsofis614 Simpler, yes. But simpler does not mean easier. An O'Neil cylinder is a megaproject, plain and simple. Meaning that building one would take decades at the very least, cost an incredible amount of resources, and they have to be durable to a degree that a smaller spaceship, even an interstellar one, would need to be. So don't think Humanity couldn't, it chooses not to because of the cost. Not only in money, but time and resources.
Not to mention the exacting specifications one would have to be built to, which means that it has to be able to work perfectly, all the time, every time, without an expectation of full maintenance, for decades to centuries. I know what goes into making something that is going to space and is expected to be there for the long haul.
And that's just the construction. What about atmosphere? What about sustainable water or food supply? Easier to do ships that are smaller and more temporary or can be repurposed for other things.
@@bustavonnutz The strength difference isn't just because of gravity. Which, mind you, we would have to adapt to as well. It's also things like musculature and how it is used. Also, mass doesn't change regardless of gravity.
While I have never been infatuated with the Avatar movies I have really enjoyed your realistic exploration of them.
Never thought I'd see this video happen. I admire all your material... and I also really like Avatar, so this is a nice bonus for me.
You can count on Astrum to change the thumbnail and title 5 times within a day for new videos 😂😂😂😂
@@SeriouslyWeirdDream yea it’s unprofessional and annoying though .
Seeing this video talks about many speculative biology topics, Id recommend the channel Curious Archive. They have a series dedicated to these kind of works. Not just alien biology but fantasy biology and also how life on Earth would be like millions of years in the future. Etc.
What would the planet's gravity do to the moon? Thinking about about the inner moons of Jupiter are basically ripped apart by the intense gravity of Jupiter
It would have more volcanic activity, but that wouldn't make it uninhabitable. Earth has quite a lot of volcanic activity as well compared to other planets in our solar system after all.
We can feel that James Cameron takes good care to polish every little detail in his movies ! that's what makes them so great !
There is only one thing that bother me with Avatar: All the fauna seems to have evolved to a 6 limbs creatures! the na'vi are the only exception to that! does that mean some catastrophy happened? or maybe even the na'vi are alien to this world? We can go very far and think that maybe they are the result of the human federation experiment to create a humanoid creature on this planet! hence the avatar program !
I think it´s more likely the na´vi do just occupie a different ecological niche, which favors four limps.
@@ancientcolors But every other mammal-like creature, including the small pseudo-primate from the first movie has six limbs.
There actually is an explanation for why the Na'vi have 4 limbs in the first movie, though it is hard to explain without images.
Basically the Na'vi are not the only 4 limbed creatures on pandora, in the first movie we see creatures called Prolemurus who are the closest living relative of the Na'vi, like the Na'vi they have lost 2 of their 4 eyes, have lost one of their neural queues and have hair on their heads, most importantly they have 2 and a half limbs, they used to have 6 limbs but over time their 2 sets of forelimbs have fused up to the elbow
Not only that but the prolemurus have 2 fingers on each of their 4 hands and the Na'vi have 4 fingers on each of their 2 hands which leads us to presume that in the evolutionary history of the Na'vi they ones had 4 forelimbs each ending in 2 fingered hands which then fused over time
The prolemurus are a living missing link between the Na'vi and the other animals of pandora
This whole thing will be a lot easier to understand if you look up what prolemurus looks like, their arms are pretty interesting
This fusing of limbs is the reason why Na'vi also can't punch, their arms just aren't developed for it, their hand and wrist bones arent built to take the impact
@@kieramcadams4103 the prolemurus don't actually have 6 limbs or 4, they are in a stage of transition from 6 limbs to 4 limbs, the same way that the Na'vi lost their extra limbs due to the 4 forelimbs fusing together
There are lemur-like creatures on Pandora that have 4 partially merged arms, the upper part of the arms is merged into one while the part below the elbow is split into 2 pairs of arms. Maybe they are an inbetween step of the evolution of the Na'vi where their 4 arms fully merged into 2 arms. Or maybe they just lost a pair of limbs over time like how whales lost their hind limbs.
Or maybe the Na'vi just have different lines of ancestors than the other creatures there.
Good video, thank you. I wasn't hooked by the Avatar storyline but the film is beautiful. A similar video on the planets shown in Interstellar or Dune (Arrakis) would be good.
I think the mountains wouldn’t be possible under two teslas, as stated in the movie. Superconductor or not, that would require about 100000 Tesla to lift those mountains which is like magnetic field of neutron star.
In that magnetic field, your blood will fly one way, while water will fly another.
Theres an old MMO that never had much popularity called Shores of Hazeron. Habitable moons orbiting gas giants were always my favourite places to colonize. Theyre so pretty!
The only problem with Pandora is that it would be in planet’s shadow for a substantial period of time. How this would impact its heat would be dependent on its GHGs, and the length of time in the planet’s shadow.
Considering the fact they a bit bigger star which doesn’t sound like much but it would make a difference so my guess would be that it’s wouldn’t be that big of a difference with temperatures
It might be close enough for tidal heating to affect it's temperature and that would also be close enough to orbit in a few hours, depending on Polyphemus's mass
@@FleshWizard69420 : True.
Would not be a problem.
The earth, its crust, and particularly the oceans, store a very high ammount of thermal energy. This energy has little means of escaping beyond radiating in space, which is very inneficient
Would the sun dissapear suddently, the air temperature at surface level above ocean would still be above 10 celsuis around the equator 6 months later. And continental land would be above 0 around said equatorial zone at that time
A few days without the sun is not sufficient to freeze everything. Its a relatively slow cooling process that takes a couple years.
After a year, the ocean surface temperature around equator will be around zero celsuis.
The ocean thermal energy firdt dissipates into atmosphere, and then said atmosphere will dissipate it into space very slowly
During the couple days into the shadow of Pandora’s eclipse, you could expect a drop in temperature of a couple degrees celsuis, specifically over land far from oceans a drop of maybe 5 or so degrees.
In coastal and ocean regions however, you will likely lose only a degree or so.
Such a temperature change would not be dangerous as temperatures already vary more temperature from day to day due to weather patterns
@@FlorenceSlugcat: I agree, the heat capacity of water is huge. I guess it’s just a matter it’s equilibrium as it cycles through. We have our milankovich cycles and I’m sure Pandora has its cycles.
A spectacularly crafted video here. I was mesmerized. The speculative/analysis stimulates the imagination. Well done. Astrum.
This video was a nice change of pace, Alex. You should do it more often.
Not going to lie... when I clicked I was thinking Pandora from Borderlands...
What about the tides created by the gas giant’s gravity so close to Pandora? It would be full planet tides, I imagine.
I would love to see more videos like this talking about fictional space settings.
Same. I've often wondered just how feasible some of the science in movies is e.g. Dune's ornithopters.
Dan Simmons’ ‘Hyperion’ written in the 80s has floating islands that are explained to be fully alive with motility and sentience .. perhaps the inspiration?
Awesome content with great topics
Small correction: it is not widely accepted that during the Mesozoic era there were more oxygen than now. As far as I know, most experts do not think it's true, and there is no evidence of it. Other than that, it's a really nice video. I learned a lot, thank you!
I heard before from a documentary that there was considerably more oxygen back then. That doesn't mean it's true of course, but there must've been some reason why some scientists (or at least science enthusiasts) in the past thought that there was more oxygen back then. Would you happen to know where this idea came from?
@@jeffbenton6183 Unfortunatly, I do not know what is the exact source of this idea. However, it looks to me like it is really old (I might have seen something like it in old russian textbooks, but I am not shure about that). After some searching, It appers that it is not so much the lack of evidence, as absence of consensus. As a modeling study from 2016 states: "The results of such studies differ greatly, to the extent that today’s atmospheric mixing ratio of 21% might be either the highest or lowest level during the past 200 m.y. " (Benjamin J.W. Mills et al, 2016). It seems that different studies look at different aspects (like air trapped in ancient amber, gasses trapped in rocks and paleobotanical evidence), and all of their results do not really agree with each other. I am not an expert in this field, far from it, but if I had to bet, I would say that Mesozoic was a thery long era and surely O2 levels flactuated during it, but I doubt that they ever reached anything close to the Carboneferous, and most likely were much closer to the modern levels.
@@absentfish1706 Maybe confusion with the Carboniferous O2 levels is a reason for the idea's spread.
I only remember reading about them being higher during the Cretaceous period rather than the entirety of the Mesozoic era. But I have never been exposed to a consensus the other directly, interesting.
@@absentfish1706 Air, or gasses in general, can easily diffuse through thin solid matter.
Amber is generally not large and thick enough to not allow diffusion of air particles and molecules.
Gasses in rocks however might be the best we have as evidence of past atmosphere mixtures.
Despite this even gasses trapped in rocks don't show much signs of high O2 levels in the past.
Perhaps somewhere far away in another Galaxy or within our Galaxy there may be world like Pandora..... we will never meet them neither they will , they are busy in their own life and we too 💔💔💔
I mean yea obviously There's gonna be life in another planet cuz millions of galaxies
I've been becoming increasingly interested in realistic near future science fiction that doesn't break the laws of physics.
Yooo! Didn’t think a video like this would come out!
If humans are advanced enough to modify genes and interstellar travel, can't they just farm raw materials from asteroids or space dust and synthesize the substance they want on Pandora?
Yep
That's probably why the sequel introduced a second, more impossible MacGuffin for the humans to chase after.
Real great topic! Thank you man.
I've never had an interest in these movies. So I am pleasantly shocked at how much they thought about the world building as far as the environment goes. I probably wouldn't notice it consciously while watching but subconsciously it would make the film reality vibe alive.
The problem with gas giants is their enormous gravity which attracts metaorites. It drasticaly increase the chanche of an asteroid impact on its moon. Even if there are a habitable moon around a gas giant, such impact would surely happen and will surely make the moon uninhabitable
The notion of a habitable world orbiting a gas giant was explored in depth by Robert Sawyer's 'Quintaglio' books. The fact that the main continent was always pointed away from the gas giant let to a major plot point of what happened when explorers traveled to the far side of the moon for the first time, and discovered this gigantic object in the sky, which became their god.
You should discuss the concept of the planet being almost a supercomputer, considering how the root systems and all the life connect and act as almost a brain… really cool to think about
meanwhile, dropping off a single, or at least two more BOR7 unit(s) on that said-rock, and then sit back and let those said-Old One era/pre-Sirius era units do their....work.
interesting prospect... if the earth was tidaly locked like pandora orbiting a gas giant and the center face would be the middle east jerusalem mekka lengh degree then basically the natives of the americas would never know they orbit a gas giant and probably the japanese, nz and a couple more
I'm offended by you saying I've been living under a rock sir, because I happen to be living on top of a rock.
I demand an apology sir! 🌍
I am a rock and as such I hold no grudge. Technically I live under, on top and within a rock. Space is very relative.
Thank you very much for making this video.
Loved this video!
I wish aliens in movies would not look like us, with typical head, hand and legs. I wish the producers have little bit more imagination.
I agree, but I think without human like facial expressions it would be really challenging to get the audience to connect with the characters. One of my favourite alien representation was in the movie 'Arrival'. The movie itself was average but the aliens that were portrayed and the way they communicated really intrigued me. I would say they were the most imaginative aliens I've seen on screen.
Never expected Avatar to hold up to scientific scrutiny.
Does it, though, or are y'all just a buncha blind stans?
Astrum... Tank you, I am a huge avatar fan. Its nice to see some content that doesn't bash the universe.
I would love to see you Alex to make review on movie interstellar and explain gravitational waves and gorgantua
I still don't understand how humans can jibe the time and date during interstellar travel with the time and date used on Earth
MORE VIDEOS LIKE THIS PLEASE!
I'm so happy you made this video
Glad you did this one! It's a beautiful movie.
Are there gas giants but they are oxygen and terrestrial, ? Or is this a size thing where gravity or something else wont allow it?
How about gravitational effect of the nearby planet on especially Pandora's oceans and seas? In the movie, it doesn't seems notable, but in reality you can only think of how much a small moon like earth's has on our oceans and seas activities.
Great video! Can you do a similar sci-fi analysis video on the Expanse series?
Could a gas giant form within the habitable zone of a star? Or would the habitable zone for the moon be based on the moons distance from the gas giant (i.e. the gas giant itself is providing the habitable zone for the moon)? And if so (the gravity of the gas giant provides the energy via tectonics, etc) would that moon have enough light for plant photosynthesis?
I’m not sure, but we may have ruled out Polyphemus sized planets in that system?
Excellent video
12:42 Not plausible either, if those mountains were filled with unobtanium, then there’s no reason they try to take down the large tree. They could’ve just mine the floating mountains
Before I watch, is there spoilers from Avatar 2 in this video? I haven't watched it yet. Thanks.
HELLO? CAN ANYONE REPLY? DOES THIS SPOIL THE SECOND MOVIE?
Day 8 of not knowing if this spoils the second movie.
Day 12 of not knowing if this spoils the second movie.
Month 3 of not knowing if this spoils the second movie.
Hi, does this spoil the second movie? I haven't seen it yet still.
Biggest problem I have with hallelujah mountains is where does all that water comes from?
Rain? It's a rainforest. The humidity and condensation are intense.
WOW... This video is rly good made. I knew some things you mentioned, but i'm again surprise how real this world can be.
And...Whether it's real or not, it looks great! And no one can deny that.
If magnetism was strong enough to make float heavy loads, any metal tools will be strongly affected by pull/pushed (weapons, choppers ... )
One thing that is ignored is the effect of xenon on sound wave frequencies.
This is why I love avatar because of all the realism it has everything from the near future technology, the flora and fauna, and Pandora itself!
A very interesting episode ❤
wow what a fantastic video
I don't know about the second movie but the first one certainly put some effort into trying to make it a bit more in the right direction than your generic scifi.
Especially with who they had help them with designing the creatures
It's not really oxygen that contributes to large flora and fauna. Plants feed on carbon dioxide. High atmospheric carbon dioxide is what allows for massive plant growth, and in turn massive animals which feed on those plants.
About the “Unobtanium”,
I think it can actually be metallic hydrogen, which is known to be a room temperature superconductor. That way it can stay suspended in the magnetic flux, thus creating the hallelujah maintains and everything else.
According to some of the theories, immense pressure inside the big gas giants can create metallic hydrogen and this metallic hydrogen can keep its metallic state even after there is no pressure.
My theory is that, in the past, two gas giants may have been collided and the metallic hydrogen got thrown out. After some time, just like our moon, pandora could be created from the debris cloud.
Awesome video as always!!! Thank you for your work
I was a bit dismayed the space travel bit at the end got cut off.
Are you planning to do a video about the interstellar spaceflight technology in the movies? That'd be cool.
Great video. I really love your content. Keep up the great work.
The first Avatar movie was much more compelling in every way.
Not every way. The first movie was pretty much just Dances With Wolves/ The Last Samurai in space, while the second, not so much.
@10:21 , more oxygen in the atmosphere didn't allow dinosaurs to grow bigger. Blue whales are larger than dinosaurs so if that was the limiting factor, they couldn't have gotten that big.
This is compounded by two facts:
1. Dinosaurs likely had the highly efficient unidirectional respiratory system characteristic of birds (which allows them to exert themselves at altitudes at which we'd asphyxiate at).
2. Blue whales are holding their breath the majority of the time and usually use ~85% of the oxygen that they inhale.
So relatively low concentrations of oxygen in the atmosphere would have an even larger impact on a whale than it would a sauropod dinosaur.
Very good vid. I have to point out though that oxygen is not why dinosaurs got as big as they did. A combination of hollow bones, efficient breathing and egg laying. During some periods oxygen was actually lower, yet dinosaurs still remained large. Although this is just a nitpick. Again great video
A strong enough magnetic field to levitate a mountain would cause the iron in a humans blood to boil.
I was thinking maybe the Floating Mountains might be possible if Pandora orbits just *barely* on the Roche limit. Close enough that a tiny little part of the planet is just a *liiiiiiittle* bit too close to the Gas Giant
Then the moon should be experiencing near-constant moonquakes 😢
@@guyman1570Not just that. It would be a volcanic inferno.
Call me a chump but the first time I saw this video in my subs the thumbnail was on an Pandora creature, and I didn't think that'd be interesting. Now you've changed it to being about the planet and that peaked my interest and here I am - thanks for the change!
Very cool. Hopefully I get to see hour exploration of the moon Titan in my lifetime
Space fantasy as a genre has some mystical magic to it (Ewya in Avatar's case) but the science part is usually grounding very firmly in hard science (the plausiblity of Pandora itself)
When a science channel becomes a series recap channel 😂😂
Videos like this are really fun.
This movie really just struck me as Fern Gully again. Visually amazing but a fairly standard plot under that.
Fern Gully is great and that leveling is still happening. The message has been lost though. I don't think people care anymore .. or not enough do. Witness the oceans becoming a plastic and chemical garbage dump. Hopefully, if you are correct, it might re-ignite some international cooperation on several fronts other than just CO2 which is a problem but there is some that are more serious and immediate
Dang, that was interesting and more possible than I would have ever thought, at least until I saw the title and I knew it had to have some interesting possiblities that would be very plausible and all... Loved it. Do we have anything like that "Masterworks" thing but instead of art, like science..... I appreciate art, but I'm more of a nerd soooo...... 🍻🌎❤️🌮🤓
Perhaps you should have bought and read _"The Science of Avatar"_ by Steven Baxter who is a sci fi author with a background in engineering and mathematics and sticks close to real science in his novels before making this episode. It's supposed to answer all the questions posed in this video.
