One possibility for locomotion within planetary rings of gas giants - electrodynamic tethering. If an organism can develop a voltage across its length, it can push around on the intense magnetic field of the gas giant, allowing slow but zero-propellant movement. The cool thing is that this could work even on a microscopic scale, and would be easy to evolve if the organism used photovoltaics for energy.
Archer01 when he was talking about needing to give their spores enough thrust to disperse, I definitely thought imparting even a tiny electrostatic charge on such a lightweight particle would be enough to give it a decent push. It would probably start with having its electron transport chain oriented in such a way as to generate voltage at cross the length of its body, with one end being near its gonad. That would give it a reproductive advantage by dispersing it’s offspring further away into non-competitive territories and spread to unexploited areas more quickly than others. Breaking that voltage chain down into discrete cells would make it more efficient and create electrostatic “ripples” across its body, right? It shouldn’t be too hard to go from there to an electromagnetic caterpillar sort of thing like I think you’re describing...
We have a recently discovered bacterium (I can't recall the full name, "D. antarcticus") from Antarctica that is said to "live off of air alone". It seems to require no sunlight, nor any water, and though it's mostly dormant, it has an absurd gamma ray and temperature resistance. Really cool. And really weird. Makes you think just how far evolution could be pushed.
Those kinds of species are highly specialized, though. Cacti, for example, can only thrive in an arid climate. It would die very quickly in a place that gets more than two or three inches of rain a year.
The Nerds: "We want deadful and majestic monsters of the void!!" The scientists: "Space Moss." The nerds: "...." The scientists: ".... fart propulsion?.."
I really am only interested In large space creatures space plants or fungi doesnt interest me which is odd for me since I have a small obsession with botany
@@enklaev1465 what about humanoids that generate their own source of sunlight and thrive on space popcorn? imagine just pop the popcorn in their own hand? its not real popcorn though. what is it?
And then there’s me, writing a science fiction novel that includes space algae that functions similarly to nanomachines, can mimic larger technology, and gets more intelligent as more of it collects together (to the point where the largest possible size, a gas giant with a nutritious core and a living atmosphere, has superhuman intelligence, and a mass the size of a rat is already sapient). Oh, and if they so choose, they can permanently genetically modify themselves to fit in with any potentially habitable planet’s ecology, or start said ecology if it doesn’t already exist.
Yes, bonus episode today :) We've one next weekend too, though this is more part 1 of this Thursday's video as the combined script seemed too long for one episode and we're considering one or two more follow ups anyway. Just as quick apology, I won't be around to answer comments most of today, I'll try to get back to everyone tomorrow, but I promised to help paint my village's pavilion this afternoon and forgot I had an episode planned to come out.
Well, you DO have to consider the implications of timezones. Timezones dictate that if you take the planet as a whole, rather than any given location, the length of a single calendar day is 48 hours, not 24... So depending on your location on the planet compared to Arthur, and his typical upload schedule... You could be looking at wednesday or friday without violating it being 'thursday' at the time of uploading. however, since it's currently in the range of saturday to monday, that doesn't explain the present situation.
There are some bacteria in the oceans that have magnetic particles inside them. They seem to use it to navigate (or at least orient themselves upwards) in water using earth's electromagnetic field. I can't see why microscopic organisms wouldn't develop such strategy to navigate a planet's electromagnetic field in space.
Life on earth remained "simple" for 3.5 billion years before more complex forms emerged- It's hard to imagine life doing better in an environment without pressure and a liquid solvent.
I would agree. Life did not even reach the relatively hospitable areas of tropic and wet land until relatively late, and even to day, is quite scarce on much of the earth's surface. The artic and deserts are relatively lifeless compared to the forest regions, as is the deep sea and even much of the open surface oceans. If life exists in the outer space, one would assume that someone on earth could evolve sub-zero photosynthesis, covering the ice caps in moss, or flying microbes would exist on earth, creating "cloud algae" ecosystems.
@@blkgardner flying microbes do exist though, and there are single cellular algae in the air. And what generally stops inhospitable regions of Earth from supporting big ecosystems isn't inability to survive there, but lack of enough resources. This is backed up by existence of ecosystems in underwater geothermal vents, there are resources to be consumed so in spite of inhospitable environments an ecosystem has formed
Great episode. Really got me thinking. One thing that occurred to me is that if we were to find some form of space whale and were considering 'taming' it to serve as the newest beast of burden to assist our exploration, it would almost certainly be one of the greatest controversies in history, and not simply because we found an alien life form.
Void Ecology is one the most amazing and badass concepts I've ever come across. Thanks for the video, I'm sure going to have some fun thinking about life in the vacuum of space now.
I would be inclined to call a space apex predator an Orca -- seeing as they are known to grab a large Great White shark, flip it over inducing _tonic immobility,_ and then rip out and eat its liver and gonads. Orcas are the apex in the ocean.
Thanks, Isaac. I've given some thought to void ecology too, and came to similar conclusions about space-coral and the like. I had an idea for a sort of space whale that evolved to survive in the vacuum as its planet lost its atmosphere, as you suggested. However, my idea was that its larvae needed an oxygen atmosphere to develop in, kind of like how a dragonfly larva or tadpole goes from living in the water to living in air, and the parents' respiratory organs adapted to excrete oxygen and absorb CO2, so they could carry their young until they could survive in space. It was a contrivance to make the creatures also usable as human spacecraft. I also had the idea that the only way they could get enough energy to do that in deep space would be to have some kind of molecular machine like the ATP synthase, that grabs atoms and fuses them together one at a time by pressing them together like a vice. The energy released would be strong enough to break chemical bonds inside the molecular machine so that things like carbon dioxide could be turned back into oxygen and fuel, kind of like photosynthesis, as well as allowing the creatures to manufacture elements rare in their natural diet, while eating nothing but interstellar hydrogen, collected with a massive magnetic field; another contrivance; not sure how realistic it is, but I hope my ideas can spark your imagination as much as yous have sparked mine. Thanks again for the videos.

I get the usage of Sharks as the apex predator analogy as it works largely within public opinion, but Killer Whales are the current apex predator of the oceans for accuracy. Oceanic (Offshore) Orca prey on Great Whites and this only seems to be increasing likely due to ecological pressures. Packs near the Gulf of Mexico and South America have been seen to specialize in it. They exploit the shark's "tonic immobility" which is rather fascinating.

I love this channel! I just want to say about the purposes of evolution-- things can develop even if they don't give an evolutionary advantage. This happens all the time. Most mutations are adaptively neutral in that they don't change the survivability of the species. I should note that there are "sensitive" areas of the genome that have little wiggle room or certain death, and there are others that change easily and often without messing with the survivability of the species. The cool thing is which areas have wiggle room and which don't can be different depending on the type of life, such as Cephalopods' use of "RNA Editing" which is considered disease in humans, but allows them to adapt rapidly. Anyway, the idea that something won't proliferate unless it gives more survivability isn't correct, is all I'm saying.

So it's not some weird local accent but just a personal speech defect/disorder? How disappointing. This should be upgraded to some kind of national dialect.
Man my imagination was running wild watching this. A most wonderful surprise to have this Sunday and watch while eating lunch. Fantastic and informative as always.
If there was complex life living in the void. I would imagine it being a very thin ribbon, so it can collect the most energy from radiation, and with the least mass. It would be very long and have two massive eyes, both to collect light, and use parallax to find food. It can use comets tail as a food source. It may be able to move around space by using a type of ion thrust by using the suns energy and there "alian" biology. Or if thats impossible, it could change its body to reflect or absorb light. With this, it could act like a solar sail. Any thoughts this? Edit, wrote this before watching :/
Assuming it was living around a star with high enough energy to be at least somewhat productive in the blue-light range of wavelengths (if you're worried about evolutionary time constraints, don't be, as due to how much light stars make, blue-light photons need not even be the primary output, a star only slightly bluer than Sol could work fine), it absolutely could alter its own blue-light reflectivity to act as a solar sail quite easily, if it were to possess barb-knit (like on birds on earth) pseudofeathers (not on a derived dinosaur, not a true feather) (They also further increase its surface area!) with the "quill" being more like a muscle-controlled sea-urchin spine than a hollow feather shaft from an earth bird, and with the barbs having blue-light-reflective microstructures similar to those in the wings of jays on Earth. The easily-movable nature of the pseudofeathers would allow the creature to separate and re-hook the vanes of its feathers to respectively disrupt and restore the microstructures reflecting energetic blue-light photons to propel it around the star system, as well as possibly helping it more easily sweep dust particles towards whatever it uses to absorb nutrients.
I love the fact that there is a bit of a science group of individual youtube channels that all collaborate together, "Physics Girl", "Up and Atom", "Vsauce", "Veritasium", "SciShow "ect,...

I think the creepiest thing about this is that the ISS stuck Salmonella out in space and it not only survived but grew like crazy and became unkillable. They had to toss it at the sun. I couldn't find the name of it but I did find the NPR article from 2007 if that helps you look it up.
Some animals use chemical reactions as a defense mechanism, and so I wonder if this could get modified for propulsion if an animal with this type of defense mechanism migrated to the vacuum of space.
No to space whales, but perhaps a yes(or a very solid maybe) to space kraken? Well, the cuttlefish and other cephalopods anyway ...my fav. btw Also perhaps a "coral" reef and archaebacteria...
Awesome! What a nice surprise. I got snacks and a drink and am now ready to see what the void has to offer. The future sure has a lot to offer us if we manage well these days. Love 👊🐶🌏🧙♂️👍
Great video. This highlights an issue many people appear to miss. This being that the species we find in extreme environments, such as hydrothermal vents, are clearly adaptations of existing species and thus did not originate there. Life is extremely hardy and adaptable once it has got going, but we have no evidence either way as to whether it can originate in such conditions. It could be that the under ice oceans on Europa, Enceladus etc. are currently sterile as the conditions are too harsh for life to get a foothold, BUT could be seeded with life from earth which has already adapted to harsh conditions. Only one way to find out if course 🙂
I have often wondered if life could have come to be shortly after the big bang-- and found it to be warm and leisurely, with plenty of space, plenty of time (those metrics scaled differently, to say the least). And perhaps the life evolved to the point that they could wonder whether life would be possible in the unimaginably cold, tenuous, and slow distant future which is now for us.
@@isaacarthurSFIA Yeah I'm bad with schedules but it does make my day with a pleasant surprise every time so maybe I'm training myself with positive reinforcement lol.
Oh yes! I was fascinated by the idea of life in the vacuum of space, but it was hard ti imagine how it would evolve. These ideas of cryovolcanoes, and mountains on small moons make a lot of sense! Also biological ships- can't wait for those episodes. I have a feeling that's the future, ships made by steel etc will be super crude in the future , ships will be created based on some kind of DNA, so it can fix itself and build its own parts.
BINARYGOD I, too, was very offended by him glossing over the oxygen revolution allowing for high-efficiency respiration and building large, eukaryotic cells that would be able to create specialized multicellular organisms that could even include dead cells as a part of itself... oh, and also: gross footage dude...
I know I'm late, but I found nothing bad about it. Not pleasant to look at, but certainly not gross. Then again, I just came back from, among other things, scooping heaps of horse shit unto a pile of it.
All I can say is I'm blown away by your intelligence finding your programs is a revelation for me it feels like I'm home you now have a new loyal subscriber
There's also (thanks XKCD) the whole Shadow Biosphere thing : life that is not carbon/oxygen/DNA based and that we'd never recognize as such unless we revise our criteria.

I am ecstatic that you have decided to discard your 'speech' disclaimer. Kudos, and excellent content as usual. Cheers Isaac!
I've always wondered if this sort of thing was possible. The space nautilus was hilarious in Archer.
* here's space Kraken*
* Kerbal Space Program leaves chat*
Isaac, you ever read themangas of nihei tsutomu (Biomega,NOISE, BLAME!, Knights of Sidonia, Aposimz,etc). They are Basically the things you discuss (megastructures, AI, Bioengineering, Generationships, Void Ecology) in different Scenarios. They're pretty good.
Nihei's imagination is godlike ... and disturbing in fascinating ways. Also anyone who wants to get into him should skip Knights of Sidonia. He made it to annoy his daughter who kept pestering him to make a shonen series so it's a total mess.
Blame is a mesh , just one problem, thermodynamic, but still good scy story' i like it
Five Star Stories, Outlaw Star, Lost Universe and Macross.
The last time I was this early the universe was still in the bathtub episode.
This was awesome, so many things I hadn't even contemplated before. Lifeforms evolving to live on rings is a very interesting idea and seems plausible.
Also love Jade, can't wait for the collab.
As someone who deals with psoriasis I felt deeply uncomfortably familiar with the feeling at 9:35
I love how you say Ooorth instead of earth ^^ very relaxing to listen to
Yeah it's weird, I never do that with my speech therapist anymore but keep accidentally doing it when narrating.
@@isaacarthurSFIA Don't change it! None of wants you to talk like Documentary narrator :D
I love the Stories you're telling and brighten up my day and my view on the future amongst all those news about climate change and how we are all about to die. Those videos just give me a good hope that everything will work out ^^
So it's not some weird local accent but just a personal speech defect/disorder?
How disappointing. This should be upgraded to some kind of national dialect.
Man my imagination was running wild watching this. A most wonderful surprise to have this Sunday and watch while eating lunch. Fantastic and informative as always.
If there was complex life living in the void. I would imagine it being a very thin ribbon, so it can collect the most energy from radiation, and with the least mass.
It would be very long and have two massive eyes, both to collect light, and use parallax to find food.
It can use comets tail as a food source.
It may be able to move around space by using a type of ion thrust by using the suns energy and there "alian" biology. Or if thats impossible, it could change its body to reflect or absorb light. With this, it could act like a solar sail.
Any thoughts this?
Edit, wrote this before watching :/
Assuming it was living around a star with high enough energy to be at least somewhat productive in the blue-light range of wavelengths (if you're worried about evolutionary time constraints, don't be, as due to how much light stars make, blue-light photons need not even be the primary output, a star only slightly bluer than Sol could work fine), it absolutely could alter its own blue-light reflectivity to act as a solar sail quite easily, if it were to possess barb-knit (like on birds on earth) pseudofeathers (not on a derived dinosaur, not a true feather) (They also further increase its surface area!) with the "quill" being more like a muscle-controlled sea-urchin spine than a hollow feather shaft from an earth bird, and with the barbs having blue-light-reflective microstructures similar to those in the wings of jays on Earth. The easily-movable nature of the pseudofeathers would allow the creature to separate and re-hook the vanes of its feathers to respectively disrupt and restore the microstructures reflecting energetic blue-light photons to propel it around the star system, as well as possibly helping it more easily sweep dust particles towards whatever it uses to absorb nutrients.
Best channel for those obsessed with life, physics, and transcendental evolution.
But today isn't Thursday. How confusing, yet appreciated.
Dude! Most unexpected. And I thought I was already having a great Sunday! Thank you Mr. Athur. Happy Arthursdaysunday!?!?
Sunday became Arthursday? Is this time dilation?
A R T H S U N D A E -- a delicious apertif to beat the summer heat.
@@leeterthanyou and now I'm hungry, good thing I've got ice cream in the freezer lol
@@skyemorningstar166
Good snack choice. I went for the classic tortillas and humus.
My imagination is going absolutely wild after this one.
Did you listen to the Momentum story?
Lithobraking? I am unfamiliar with the term, but I am all too familiar with the experience, as the dents in my car will attest.
lithos is the greek for stone.
The quality of my day has just quintupled.
I love the fact that there is a bit of a science group of individual youtube channels that all collaborate together, "Physics Girl", "Up and Atom", "Vsauce", "Veritasium", "SciShow "ect,...
I am glad I get to enjoy regular surprise-content from Isaac.
Refreshing, nice topic. Thanks
Just wanted to say
You’re speech has gotten amazing. Sincerely. Man I tell people that are worried about how there voice sounds
I tell them to head to your channel
Your inspirational
Also love your content
I have waited for this episode since forever
Me too!
I think the creepiest thing about this is that the ISS stuck Salmonella out in space and it not only survived but grew like crazy and became unkillable. They had to toss it at the sun.
I couldn't find the name of it but I did find the NPR article from 2007 if that helps you look it up.
Ahhh, this is the part of RUclips I always feel great after experiencing.
So maybe there could be a real “Treasure Planet”-like system out there somewhere. Space Whaaaaaaaaaaales!
Wouldn’t you be able to make whales in space with a nuke and an Infinite Improbability Drive
Or a bowl of petunias.
@@D1SCORDANT3 Oh no, not again.
"Life on Orth is very divorce". heheheh great content as always!
I just invented rock hopping jumping void spiders with telescope eye's.
Are you talking about the rock-hopping spider story he linked?
A video on Monday? A surprise, to be sure, but a welcome one.
I see what you did there...
Hello there...
Some animals use chemical reactions as a defense mechanism, and so I wonder if this could get modified for propulsion if an animal with this type of defense mechanism migrated to the vacuum of space.
No to space whales, but perhaps a yes(or a very solid maybe) to space kraken? Well, the cuttlefish and other cephalopods anyway ...my fav. btw
Also perhaps a "coral" reef and archaebacteria...
Awesome! What a nice surprise. I got snacks and a drink and am now ready to see what the void has to offer. The future sure has a lot to offer us if we manage well these days. Love
👊🐶🌏🧙♂️👍
12:30
finnaly, ive waited for this from my comment since last year
You've got so many GREAT videos, but i have come to realize this is my all-time favorite.
Thanks for the extra upload!
This is an amazing episode Arthur, thank you for your work and expanding my mind. Void ecologies is definitely a rad concept
Great video. This highlights an issue many people appear to miss. This being that the species we find in extreme environments, such as hydrothermal vents, are clearly adaptations of existing species and thus did not originate there. Life is extremely hardy and adaptable once it has got going, but we have no evidence either way as to whether it can originate in such conditions. It could be that the under ice oceans on Europa, Enceladus etc. are currently sterile as the conditions are too harsh for life to get a foothold, BUT could be seeded with life from earth which has already adapted to harsh conditions. Only one way to find out if course 🙂
Awesome video, 25 minutes ago I wouldn't have thought of this sort of ecology as plausible, can't wait for the follow up.
Man I usually get amazed by your topics but this video has blown my mind!
Really fascinating topic. Love hearing about ecology and related topics - reminds me of the Dune books.
Scotty, activate the Dookie Drive!
Sorry Isaac, my inner six year old took the reins for a moment.
I have often wondered if life could have come to be shortly after the big bang-- and found it to be warm and leisurely, with plenty of space, plenty of time (those metrics scaled differently, to say the least). And perhaps the life evolved to the point that they could wonder whether life would be possible in the unimaginably cold, tenuous, and slow distant future which is now for us.
I have been waiting for this mino-series since forever!
Thanks, Isaac!!!
Always love how supportive you are for others in the field and for books both scientific and science fiction..
Thursday again. I love improvised Thursdays
[Tardigrade flexing intensifies]
Wait two video's this week? This is awesome.
:) And next week too, I think a lot of folks are skipping the end-show schedule and credits
@@isaacarthurSFIA Yeah I'm bad with schedules but it does make my day with a pleasant surprise every time so maybe I'm training myself with positive reinforcement lol.
@@isaacarthurSFIA I always stay for the end credits, but look forward to being surprised by next week's announced bonus episode, too.
Nani? Sunday? Yes isaac, yes.
Oh yes! I was fascinated by the idea of life in the vacuum of space, but it was hard ti imagine how it would evolve. These ideas of cryovolcanoes, and mountains on small moons make a lot of sense!
Also biological ships- can't wait for those episodes. I have a feeling that's the future, ships made by steel etc will be super crude in the future , ships will be created based on some kind of DNA, so it can fix itself and build its own parts.
These are the things that fuel my dreams. Thanks!
SFIA on a sunday?!?! YES PLEASE!
The Void has chosen ME as its prophet.
A prophet of profit!
Isn't that wonderfull?
Good fortune upon you MR:Isaac!
*ANOTHER TENNO SKOOM DETECTED*
Only I, Vor, know the true power of the Void!
what about plants?
I always thought the most likely type 2 "civilization"
is a "dyson forest"
Hell yes, a special surprise episode! I love you IA, meow
=^~^=
Spliff, beer and Isaac Arthur 🙌. Followed by productive activities that will help transform us into a type 2 civilization👽.
The shot of that guy scratching and picking dead skin off of his hair-lined-parts was gross. Please none of that again.
BINARYGOD I, too, was very offended by him glossing over the oxygen revolution allowing for high-efficiency respiration and building large, eukaryotic cells that would be able to create specialized multicellular organisms that could even include dead cells as a part of itself... oh, and also: gross footage dude...
Agreed. I was eating lunch. Had to stop ....
I know I'm late, but I found nothing bad about it.
Not pleasant to look at, but certainly not gross.
Then again, I just came back from, among other things, scooping heaps of horse shit unto a pile of it.
@@RandyKalff I bet Isaac has some interesting theories about how humanity can someday colonise that pile of horse shit.
All I can say is I'm blown away by your intelligence finding your programs is a revelation for me it feels like I'm home you now have a new loyal subscriber
Farts are probably more useful as an RCS than as a main source of propulsion :)
I saved my view for monday. Thank you sir. Definitely have my brain going after this one.
IT'S ARTHURSDAY
Happy summer everyone
Is it Arthursday already? Amazing!!
A pleasant surprise
I love the idea of living ships are seeding life on other planets ! Another awesome episode !
ah dammit. I misread the title as "void economy" and was like dafuq???
that's pretty much the economy I operate in. ;) I can give you money tomorrow for a hamburger today? (Wimpy form Popeye)
Confused about the void? Ask Nef Anyo, the Prophet of Profit!
Excellent exercise in speculative evolution and fascinating subject!
There's also (thanks XKCD) the whole Shadow Biosphere thing : life that is not carbon/oxygen/DNA based and that we'd never recognize as such unless we revise our criteria.
You mean non cell based? Where can i read more about the topic?
@@cristiancamilovaldiviesopo6717 en.wikipedia.org/wiki/Shadow_biosphere
almost like a cooperation with anton. very appropriate for the topic.
