- The galaxy has many stars orbited by many planets, and many of these are orbited by immense icy moons, but could others have oceans on their surface, or even life?

Oceanic Moons

Subnautica is easily my favorite example of an aquatic moon. Obviously the planet is close to Earth because it's orbiting a gas giant, but still very cool.
The moons of the Subnautica planet are massive yet there are no tides or even waves
I'm really disappointed that the thumbnail wasn't a picture of Laythe.
I think it might not be as clear what it was to non-Kerbalites :)
@@isaacarthurSFIA even playing ksp years ago with great pleasure, i wouldn't recognise laythe
I was more taken away by the amazing timing of the shot--to have an explorer standing on a slightly submerged islet and then get a dramatic shot of them staring off into the distance at the exact moment that a rogue wave trough hits and reveals the islet.
The Aquarians should call their human visitors the Bubblians because they are always expelling bubbles from their aqualungs. 🙂
Thumbs up for this because it is cute.
Would it be pedantic of me to bring up that humans visiting Aquarius would likely be in fully-sealed suits with closed-circuit rebreather gear to avoid biological contamination and that bubbles would therefore be a bad thing?
Yes, that would be very pedantic of me. At least they aren't calling us Bubblians because that's what we make when we scream in pain and/or terror...
For those interested in an interesting sci fi portrayal of an alien civilization living under the ice on a Europa-like moon I would recommend ‘A Darkling Sea’ by James Cambias … some great worldbuilding in that book, and some lovely/bizarre ideas!
Sounds good, I'll check it out. Thanks for the recommendation.
Coconut trees should be the first prority for ocean type worlds or moon if we terraform them.
And maybe avoid almonds before further research only ecological impacts of the cosmic bodies being colonized. 😅 IDK terraforming is a touchy subject; mastery of it on your own planet by yourself and other local flora and fauna is already difficult. 😊
They're important to keep the modesty of young nubile maidens on desert islands.
@@John-ou4rm Food, clothing, shelter, and fuel. All four uses in one plant.
Good point, but it does none on these surprisingly well.
Bamboo can be used for food, clothing, shelter and fuel, but grows and propagates much faster.
By the time they need to colonize a planet, yeast, algae and fungi will be much better options - and probably the same tech they used on board their ark-ship.
@@HobbesNJoe Yeah. Bamboo isn't that iconic in an ocean world. Coconut trees and crabs are.
Behold! I have seen this 4min after it was released
11 minutes here 😋
I was going mention 32 minutes, but it’s already too old 😂
Let's all rejoice
Would be more impressive if this had seen after 4 minutes
I saw this two days ago on Nebula! 😎
A planet-sized moon around a massive gas giant or brown dwarf could maybe be called an Olympian, as in one of the gods "in orbit" around Zeus. Just a suggestion, but it probably deserves its own classification - too large to be a moon, but still in orbit around a larger sub-stellar object.
Or, how about a bastard, because Zeus fathered so many of them?
Happy Arthursday!!!!!
I love SFIA story mode
Missing Grand Admiral Whatshername of the Unity
Thousands of years later the Aquarians’ History Channel will have strange documentaries every Friday night speculating about the “Ancient Aliens” (humans).
Nah, their channel will have a "we did it all" channel, explaining the submarines, floating cities and other things forged by fire as "those could have been smelted on hydrothermal vents long since dormant"
@partciudgam8478 🤣”We wuz sea kangz and sheeeet!”🤣
Happy Arthurs' day Everyone
Just like with the Apollo 13 astronauts trying to get home; even if I haven’t done the math myself, it still makes me feel good that SOMEONE has done the math. So you should never be hesitant to throw up a graphic with a chart, function, equation or calculation. One or two of them makes the video look smarter; and makes us smarter along with it!
Also, I KNOW it must be a drag on your time to pick out the musical score for every video, every week. But the music YOU pick, inspires, and moves people, just as it moved you when you heard it. Epidemic Sound is meh… It’s okay for background sound, meaning it’s better than silence. But when you don’t pick the music, it is noticeable in the finished production (I will add) by those of us who have been enjoying you for a number of years now.
-All the best to you and your family, and I do hope to meet you one of these days! -C.
I love Aquarians.
Garlic butter, squeeze of lemon and a dash of salt, mmmmmm.
Parsley, sage, rosemary and thyme....

"Remember me to one who lives there."
16:40 when talking math, I find it very helpful if the number are shown on screen, so I can follow along better.
This is the dawning of the age of Aquarians.
Is this the dawning of the Age of Aquarians? I'd like to think so!
All joking aside, I think this has been my favorite piece of framing fiction on SFIA so far. I hope we see them crop up in future topics. Excellent world building!
A fellow OVRHVN enjoyer?
Never heard of it, but sounds interesting. I think we were both referencing the song by the 5th Dimension.
@@MADGator OVRHVN is a Sci Fi world building project on DA about the trials and tribulations of humanity expanding out into space after the Outer Space Treaty is never ratified.
One of the more recent and best entries on the project was Age of Aquarius which focused on the Moon of Ganymede in the year 2585 and its ruling nation state of the Jovian Empire. It’s an interesting setting I recommend you look into.
This was the most cozy episode I watched.
Floating continent? Send the Space Battleship Yamato!
It would be awesome to see what discussion and theories about Gas Moons would be really interesting.
Interesting, but my understanding of physics has convinced me gas moons or smaller planets than Venus can't be gaseous. Maybe you mean a gas giant orbing a bigger gas giant?
Really liked your intro scenario story! I think it's a good way to lead to the topic of the episode.
I love all of your content, but this is where you really shine; storytelling. Videos of this format keep me interested the entire time. I love how you humanize these far future scenarios, making then seem almost mundane and normal, which of course they would be to the people born in that time.
Earth-like oceanic moons (that orbits Gas Giants) make starter planets in Dyson Sphere program game
As humanity find exoplanets and exomoons, ocean moons would be common compared to the earth like planets with life. Plus, we might find alien life first in the ocean moons in the example of Europa from Jupiter.
I suspect we will find 'Alien' microbes all over the solar system, but they came from Earth originally. Distributed from asteroid impacts. Ancient life evidence is waiting to be discovered.
welp, guess Imma play some Subnautica now.
Isaac needs to make a science fiction book (hopefully to become a movie some day) about Aquarius. Nothing interesting ever actually happens in real life which is part of what makes science fiction so important.
What? You are living in a time that may lead to world war 3
We do need that book/movie, for sure. That said, I kinda have to ask for your definition of the word 'interesting'.
I like the way the humans in the story treat the less technological (I prefer that term to "primitive") aliens. Not wiping them out, as many scifi has happening with us being the less technological civilisation, but neither basically putting them in a kind of zoo or safari in a Prime Directive kind of way, which, as well as letting more of them die of diseases and such, is (I feel at any rate) rather infantising.
The cynical part of me remembers humans have it in them for this story to have gone VERY differently, and it is tempting to assume we would always act in that way, playing to the worst of our natures (indeed a high tech civilisation going around exterminating other civilisations might be truly "primitive"), but we are capable of both.
Indeed storywise, if people would indulge me in some "fanfiction" of what you could call the "Isaac Arthur verse" maybe in the story's Universe, humanity has yet to meet more technologically advanced aliens (so far?) and there are some humans going around exterminating aliens and it is pot luck for an alien civilisation which group of humans finds them first.
I remember in the Dead Aliens episode (I think) it was mentioned as a possibility that the captain of the human colonists might decide to destroy the last remnants of an alien civilisation that could otherwise be sort of revived. Maybe she does decide to do that, and to even do it to living aliens, and that eventually causes SSWI (Solar System War One) back home between those who support the decision and those who think it is terrible crime, with both sides suffering many, in absolute terms (trillions), of casualties (and lots of those are "for really real" since both sides are advanced enough to blow up/delete people's digital backups), and both genuinely believing they are fighting for the good of humanity and the Universe.
Eventually, neither side can triumph over the other (especially since some nations are "fluid" in their allegiances to the general coalitions of both sides), and a truce is struck. And now both ideologies are being spread across the galaxy...
EDIT:
And as both sides prepare for a potential SSWII, in a VR simulation of a military training camp, a grizzled old veteran of the first war says to some fresh young recruits "You must remember the first rule of warfare...".

2 episodes ago i suggested sports in space and isaac informed me that there was already an episode on the subject. Just wanted to say thanks for the recommendation, it was really enjoyable to watch and a pretty fun episode.
Brilliant episode, covers exactly the worldbuilding settling I'm doing - the concept of a stormy ocean 'Superhabitable' planet, not because it's particularly analogous to Earth, being bigger, wetter, and more volcanic, but its conditions are basically supercharged for life.
I was planning on the 'Moon' in question actually having a rotation period similar-ish to Earth while it orbits a Brown Dwarf, but your info on tidal-locking being greased by a thick atmosphere and water is really helpful - the intense tidal heating and gravitational forces (mixed with the very deep oceans) cause tidal zones hundreds of metres high, flooding and then draining huge swathes of continents, while under near permanent thunderstorm and rain. Funnily, 'night' wouldn't be all that dark unless both the sun and the brown dwarf were on the other side of the planet, and the cloud density usually means that the sky is darker during storms than actual nighttime. Large amounts of sulphur and ammonia in the atmosphere too, terrible for humans, great for the native life.
Interesting
The gasses in the atmosphere are mostly the results of the ground and water. It changes and determines what kind of environment suits need to be worn.
How do you NOT run out of ideas?!?!?
Well space is huge and there's so many potential worlds out there, or types of world.
Eventually, humanity in whatever shape and abilities will be able to leave a planet in danger of destruction from local problems or exploding nearby stars. Some people might stay, but most will choose flight and find another home.
Anybody remember that Far Side where the guy is fishing in the rowboat in open water, and on either side of the frame, huge fangs and the beginnings of lips are coming up out of the water around him? The picture popped into my head as soon as I saw the title.
The videos of the creatures tht live on thermal vents is fascinating to me. It wasn't to long ago scientist all agreed there couldn't be life in the deep ocean or under icecaps.
Love you Isaac!
Activating emergency CPR. Vital signs stabilizing.
More seriously though, I wonder would dust from fall of the crushed asteroids be enough source of heavier-than-water elements for complex life to exist?.. For something more interesting than just algae and filter-feeders...
There is nothing like working while having my mind taken to another world and place by Isaac's storytelling and world building.
Superb and informative as always, Isaac.
I love your short stories. Would love to read a book if you were to write
You should write science fiction!
I think he mentioned something about writing a book in one of his livestreams a few months ago. Or maybe he just said he was thinking about it.
Isaac's world building in his informative videos is amazing.
I'm still not entirely convinced that space is real.
But i love your videos' and i have listened to over 150+ of them over the years.
Keep up the good work sir.
5:28 "deserve tears of joy" lol 😂 because aquatic beings even know what tears are let alone have them?
It would be so cool to find life in the ocean bellow Europa. I hope future missions find it. I would love to see what is lufe that evolved from a different ancester. Part of it is probably equal to Earth's. But it muat have a lot of differences. I hope they find it close so we can study it soon.
The ultimate weekend getaway
I loved all the math in this episode. It's one thing to say a thing happens (like tidal heating), but it's quite another to bring the receipts (or literally show the math).
its about time you did this topic, Isaac, been waiting for this for half a decade! lol
I love this channel ❤️🙏🏽❤️
Thanks Isaac for inspiring me with this optimism 😊
I wonder how much of a diplomatic fauxpas it would be to serve bouillabaisse at a Aquarian reception.
Behold, I have seen this 6 mins after release 😊
Horrible day shopping and i come home to this gem, great timing IA ❤
Zephyr dwarfing Jupiter makes me think it's one of those "puffy planets" seen in some star systems
My man delivers the goods with scary consistency. Thanks Isaac 🙂
Did you take into account the gas giants radiation belt?
For example, Ganymede gets about 5 to 8 REM per day from Jupiter's radiation belt. That is enough to kill a person in 2 months. The average person on earth takes in about 200 mREM a year and the yearly save amount for a radiographer is 5 REM per year.
Another great video!
Isaac, when will you be writing a space epic?
When has he not been?
@@estherclawson6876 Good point. Every episode is a great story. I'd love to read a full epic (if he hasn't done one already).
Discovering the first sapient species? This is the dawning of the Age of Aquarius.
How would swimming be different in moon gravity?
Man Interstellar is my favorite movie, funny seeing stock footage like it!
I think it inspired a lot of art
I hate being that guy, but I guess today I'm that guy.
Millennium is singular. Millennia is an acceptable plural of millennium, however, millenniums is also accepted (sometimes preferred, depending on the source).
Hearing a plural when I'm expecting a singular can take me out of a story. This happened in the first 20 seconds, but not after that. Again, I'm sorry for being that guy.
Interstellar movie has joined the chat... 😏
I always thought it would be an awesome View to see a giant gassy planet especially with rings like Saturn from a earth-size moon where the planet is huge and takes up maybe not the whole sky but a quarter of the sky or maybe something that appears several times bigger than Earth in the sky from the Earth's moon, but when I talk to an astronomer one time about this at a planetarium he said you wouldn't want to live on a moon like that because the title forces would be so strong from the planet that it would always be a erupting in seismic quakez everywhere just like Iowa has volcanoes everywhere and it probably wouldn't be habitable because of the sulfuric dioxide from the volcanoes poisoning the atmosphere but I wonder how big title force is as far as waves in the ocean could be from something like that a volcanic activity wasn't an issue earthquakes I bet every high tide there'd be waves in the ocean that would be like tidal waves on Earth possibly a thousand feet tall?
Often overlooked, ocean life not only needs energy flux, but also bioavailable minerals, and there isn't nearly as much erosion under water. Sure, geothermal vents like black smokers get you that, but without erosion runoff from continental rivers the bioavailable mineral supply is going to heavily bottleneck an ecology's biomass(even on earth, minerals and the ilk are a major bottleneck), especially as light and mineral inputs on a water world can be isolated by (tens of) kilometers of water, heavily limiting productivity. And the lower an ecology's biomass, the smaller it's populations and the fewer opportunities for evolution to find beneficial mutations, etc. Tidal heating may help offset this by increasing tectonic and thus geothermal activity, but I'd still expect it to be pretty barren.
Like if you listen to Isaac before sleeping 👍🏾
Me as well!! Then I always have to go back the next day and finish the episode 😂
There is a playlist of all Isaac Arthur SFIA Videos, chronologically, from Megastructures (the first one, 9 years ago) to January 12, 2023 -- excepting the monthly Q & A.
That playlist is at ruclips.net/p/PLbuzRoLSlpe8vTHLB4UxaB7YLt7LJC208
I have been watching these, in chronological order, for a little over a year and am about at the end of that 430 video list.
IS there a new or updated playlist with the same characteristics? If so, what is it's URL?
I wonder if tidal forces could be used as a near limitless source of energy? Technically planetary orbits are what we would consider a “perpetual motion machine“, and if that motion generates heat then you would actually have an endless source of energy. Building a machine that could harvest that would be a serious undertaking, but I don’t think doing so would somehow slow the orbit down, so you’re not exactly killing the golden goose. Passing thought and something I can’t help being curious about
It's not really perpetual motion as the tidal heating is slowly slowing the object down and will eventually cause it to either enter into a more Stable orbit or crash into it
@@camp002 Good to know! After writing that I also read somewhere that many orbital bodies eventually tidally lock. So not perpetual… Useful for a few thousand years, though, maybe. I don’t know,still a fun thought.
Can you please make channel with jre style interviews. Long form. Not just you talking at us. Ty
It’s that time of the week again.
Is it possible for some gases to become denser than water with enough pressure?

Love the math episodes, that's what got me hooked on this channel years ago. I'm not into fantasy or sci-fi novelists much but you make those interesting with the math lol
Do these moons have whalers?
Like Mass Effects Leviathans....
Isaac broer we need a scale for tight and other side volume of atoom distentc to ethoter
Whuuuuh?
just asking for a friend but, travelling a fraction of light speed, 7200 light years away, 2400??
I think he is taking into account time dilation
We live in early third millennium. He said early 24th millenia. 21 000 years into the future. At least one third of the speed of light to get there on time if launching today
Distance appears shorter when traveling at a percentage of light speed.
24,000 AD was the date iirc
@@bassmanjr100 It takes less time to cross an amount of distance the faster you go. That's how ANY speed works.
I feel its more likely that us humans would eat the aquarians and lol
I don't mind the hypothetical stories but if it lasts for the first 7 minutes of the video it kind of gets old
I agree. I'm here for the science and thought provoking possibilities to come up with my own stories.

Random question...maybe a little bit of whining...How do RUclips ads work? Is it more dependent on the viewer's activities or the uploader's?
Perhaps I am misremembering, but I recall watching entire episodes of this channel's content with zero interruptions, besides the uploader's sponsor. Fair trade, no worries. But last night, I had no less than 4, two-minute ad interruptions in 20 minutes.
Did we pass some sort of threshold of views or subscribers?? Is the uploader attempting to make or increase their profits, if there are any to even be made?
No problems with either. Just curious if there is anything I need to do to slow them down, short of breaking down and paying RUclips their "tuition fees"...
6:26 not if the Russians or CCP get there 1st
Sentient?
Your dog is sentient, your cat is sentient; hell even my bearded dragon is sentient...
But ONLY Humans are Sapient!
At least in so far as we now know.
My point is that people often misuse words...
Even highly intelligent and well educated people.
"Decimate" for instance means "to reduce by one tenth"...
And NOT Destroy, as it is so often misused today.
Likewise, people often say "Sentient" when what they mean is "Sapient"...
As in "Homo Sapiens."
'Sentient' simply means "To be able to perceive or feel things"...
So all higher order life forms are Sentient...
And even most lower order life forms as well.
Aaaaaaawwwwwwwhhhhhhhhhh
Like 👍 !
At least thats what they teach in schools. The part about the Aquarian colonization wars and the purchasing of entire oceanic ranges for plastic beads tends to be somewhat whitewashed.

5th to comment.
I am really puzzled by this guy's accent. A little similar to Scottish, but still not.
Shetand? Isle of Man? South Africa?
Can some native english speaker enlighten me?
The accent is fake, the guy's American
Isaac Arthur is American (he lives in Ohio if I remember correctly), but he has a bit of a speech impediment (which he has been working to overcome).
Early gang
I realy like this channel, but when Isaac goes off on his math, trig, algebra, tangent, Im out.
Slow it down, so I can at TRY and visualize or even GRASP what is said, Bro.
My opinion.
i dont want do die on earth, ya allah
Thank-you.
The pictures need to be accurate too to what you are saying at least. You make tens of thousands of dollars. Japanese animation cost alot.less tha. You think
Until then. I'm unsubscribing. You can do better. Write your script then go to a Japanese animation company or vet these images you are showing. They are all just Ai art of bs
I actually listen to a lot of his videos because I learn more from words than flashy anime with inhuman proportions, huge eyes, no nose, and an emphasis on goofy

Well this reflects the tevid moon of gas giant of the book the teeming universe by the speculative evolution author christian cline where the moon is 0.9 times mass of the earth and home to sapient biological species called yeatuans please make criticism of the soundness of this speculative project becouse its densest book of any single alien species are they possible
