I once had an idea of a dark planet that, despite its distance from its star, it was kept warm by a very thick greenhouse atmosphere. Due to the darkness it would cause more animals to be ambush predators because it is near impossible to actively hunt prey in darkness. Plants would use methods of chemosynthesis, or other non-light based ways to produce energy.
Another thing about high gravity is it might actually compress the atmosphere more and also tend to hold onto it better. So high gravity probably implies a thick anywhere rich in light gases. Methane and water escape are unlikely and even helium and hydrogen might last long enough to be a significant portion of the atmosphere billions of years later. Depending on just how high the escape velocity is.
Well we have to remember that Hydrogen and Helium would still be the lightest elements in the atmosohere and thus lay on the upper layer and thus have the easiest time escaping. So even with a higher gravity, we'd still need an extreme amount of those gases for the atmosphere to hold onto it. Also the Moon Titan actually has a high ammount of Hydrogen in it's atmsophere despite it's low gravity
You can find a lot of variables that can affect the atmosphere once you really start digging into the science. A large magnetosphere protects the atmosphere from solar wind, active volcanoes can vent a different mix of gasses, relatively small changes to the planetary chemistry can encourage different gasses to collect, and the planetary temperature is both affected by and can affect the atmosphere. Life itself is responsible for the present nitrogen/oxygen mixture of Earth, and hypothetically there could be a planet where photosynthesis uses a different chemical and doesn't produce oxygen. The real trick, however, is figuring out how any of this will be interesting to an audience outside of the astrophysicists and biologists. Sometimes it's more useful to start at the end point--the planet full of aliens--and use science to work backwards and find a plausible reason for it to exist.

Tidally locked planets might also allow life well outside the habitable zone as we conventionally know it. Either on the cold side of a hot planet using wind and temperature imbalance as a power source, or the hot side of a cold planet using photosynthetis.
There is also the possibility that a tidally locked world in the right spot in the habitable zone and with an especially thick atmosphere could have the entire day side being habitable, since wind currents could theoretically cause thick cloud cover and constant downpour in the center of the sunward side, cooling it off, and in a thick atmosphere the hot, dry air could blow away towards the "iris" of the eyeball planet faster than it was heating up the "pupil."
There's actually a whole genre about Old Planet settings called 'Dying Earth' (similar to but distinct from Post-Apocalyptic), named after a Jack Vance short story compilation. Other than his, the most famous example of a Dying Earth setting would be Zothique by Clark Ashton Smith, a contemporary of Robert E. Howard and H.P. Lovecraft at Weird Tales. Feel that Gas Giants also deserve a mention, given that half our solar system is made up of them. Of course they made be hard to use as settings due to their lack of surface, but there's still stuff like Star Wars' Cloud City for inspiration. About Dyson Spheres, there's also a proposed type of space habitat called a Bernal Sphere, which is similar but on a much more contained and (relatively) manageable scale, using an artificial light/heat core instead of a whole star
Fairly sure a tidally locked planet, or “eyeball planet” could have a larger habitable area, as long as it has a dense enough atmosphere. The reason Mercury has such extreme temperature differences is because it has little to no atmosphere. An atmosphere can easily regulate the temperature of a planet, even a tidally locked one. What you would see on the day side is a constant hurricane assuming there’s sufficient ocean coverage on that side of the planet, or at least constant precipitation.
There would also have to be extremely harsh winds crossing the twilight zone as the atmosphere on the hot and cold sides attempt to moderate. Said winds would likely make it impossible for anything resembling Earth life to exist on the surface, but in exchange I suppose they would also increase the concentration of atmospheric gasses dissolved in the ocean. Of course, ocean currents would also be quite severe for the same reasons.
you both forgot that mountains, rifts and valleys could be vital for the development of life on a tidally locked planet. if the planet had something like the andean mountain range or swiss alps, life could technically develop in lakes on valleys, fish like aliens could salmon their way up and end up in a fresh water lakes or ponds, maybe even piggy back algae and plankton there too alongside other microorganisms. also the mountains and hills would protect the valley from extremely harsh winds and yet if they are forward enough, the valley could be bathed constantly on light or if big enough they could find caves or move to the shades to sleep. with a constant supply of fresh water from the frozen icy winds of the dark side of the planet, you can have a feasible ecosystem even more stable than of earths. the only true dangers life could face there would be geological activities or be unlucky enough to get hit by an asteroid inside the valley. life in a tidally locked planet could survive well there, also the cave systems would be pretty good for refuge, just having a hill protecting you from the wind would be enough for life to develop. even in deserts, dunes would be vital for the ecosystem to grow, since dunes would remain unchanged with delivering shade to lifeforms. technologically, they would sail the winds via zeppelin or air balloons to conquer their world.
I don't think alien worlds will be single biome planets. That being said, one that's very different from Earth could definitely *FEEL* like, even if diverse, it's diverse within a certain extreme direction. For example Mars has: Very cold giant volcanoes with thin air. Very cold giant canyons with thin air. Very cold giant icecaps with thin air. Very cold giant rocky deserts with thin air. Are you seeing a pattern here? Yes other worlds are likely to be equally as diverse as Earth, but it might be all in a specific direction. A world with very little water would for example have many different kinds of deserts. But everything there besides a narrow region around the one big sea would be some flavor of desert.
None of those are biomes though, because life doesn't exist there (as far as we know). They're just climates. I think you'd expect different biomes on a planet with an actual atmosphere, no matter what.
I've always like the idea of a bioluminescent world, one that also kinda doubles up as a dark, midnight world. It would be its own source of light and the intelligent species there would put the various flora to good use by using it to light up their cities, alongside their electricity powered lights, it would be a neat mixture of natural and synthetic
If you use Universe Sandbox, you can also run a simulation for what if scenarios, though environmentally seen, its a bit vague, on the other hand, you can see when an atmosphere gives up, how water reacts on high gravity- high density worlds, etc, etc.
I feel like one of the best ways to change it up is to mess juuuust slightly with the athmosfere, so as to not have it be earthlike but also not have it be completely alien and unfamiliar. Some examples: -Put a very toxic/caustic/acid/etc. chemical in it. -Put the nesessary chemicals for widespread chemotrophy in it. -Fill it with spores, pollen or some other biological aerosol or powder. (Entering the more crazy side here) -Make it flammable. -Make it VERY thin or thick.
"More flammable" isn't that crazy, honestly. A modestly higher oxygen concentration would make fires burn hotter and stronger than on Earth and also be corrosive and caustic.
@@ThreadbareInc I mean, like, oxidizers AND a lot of regularly replenished fuel in the athmosfere. This would create an environment where a spark could wipe out a city before the reaction burns itself out. Think about the implications: mini mass extinctions would be commonplace, fire and firearms couldn't be used...maybe any civilization would need to be fireproof dome colonies so that fireballs can't enter or exit as easily, firestarting materials would be ridiculously strictly regulated and terrorism and total warfare would just be about turning on a match at the marketplace.
@@user-ft3jq5vi2l Well, the issue with this setup is that lightning and volcanoes both create enough heat to spontaneously ignite fires, and these phenomena would have to be common on a planet capable of sustaining Earth species.
1.5 G would not cause a regular elephant to collapse. Regular elephants are strong enough to avoid damage by tripping. Most animals are nowhere near the limits of compressive structural failure.
An elephant wouldn't go from zero to crushed with a minor increase in gravity, but the reason animals are overdesigned in this respect is because of extreme moments like predator attacks and injuries. For instance, an elephant that trips and suffers no injuries in regular gravity could very well break its leg if it tripped the same way in 1.5 or 2 Gs. Higher gravity would also cause an animal's heart to suffer extra strain thanks to the need to pump blood against gravity's pull.
The planet I'm working on is: a little bit smaller than Earth, almost as much gravity as Earth, tidally locked, an eccentric orbit, higher atmospheric pressure, four intelligent species, deserts, jungles, sea of ice, mountains, etc. I cheated a little and used an existing exoplanet for things like mass, radius, orbital period, etc.
I have heard that on some tidally locked planets the sunlight may not often reach the ground in the area directly facing the sun, as this is the point where the winds converge with whatever water vapor they may be carrying. The air then rises leading to condensation, similar to rain falling on one side of a mountain range. Boom, permanent rain cloud
One thing I considered recently is that- in theory Cloud City in Star Wars isn’t impossible. At higher altitudes, gas giants like Neptune or Uranus actually feel like 1g. It’s also not impossible the higher altitudes could be made of the correct combo of gases to allow humans to breath.
The upper atmosphere of gas giants would probably be too chaotic to rely on breathable air; one bad gust of methane and you're done for. However, some sort of invisible shield could protect a station and you could certainly filter the surrounding atmosphere to create a breathable nitrogen-oxygen mixture.
My try on this: Two earthsize planets orbit eacht other in a double-planetary system. Just far or near enough that they won`t affect each other to much or distance themself further through time. This system would be around a "big" Red Dwarf Star with 0,30 times the mass of the sun. The plants would be black in color and would be white blooming. The oceans, rivers and ponds would be red. The heaven in a almost steelgray color with a huge sun. I imagine this would be a awesome sight. And I made this a double planetary system so the planet of my storys would be tidal locked to the other planet and vice versa and not to the star to improve the quality for live to form.
I did a little bit of research on tidally locked planets. If the atmosphere is thick enough and enough water is present on the planet to generate lots of clouds, it could be possible to have less storms and more stable bioms.
One thing people get wrong about tidally locked planets is their habitability. The night side will always be uninhabitable, no matter what, but if there were enough water on the planet, then the day side would be very tropical.
I’m a big fan of high-gravity worlds, personally. The main planet from my speculative biology/technology project has a gravity of about 1.8x earth’s or so
11:52 I love how they don't even try to explain where would all the building material come from for making that sphere :J And I don't think that even bunching together all the solid matter from the entire solar system would be enough for that :J
Sentient species could 100% evolve on oceanic worlds because their way of thinking and how their technology advances could be entirely different from ours, and while we need fire they might not
Fire is less of an issue in technology and more of an issue when it comes to evolution. Fire played a key role in the development of the Homo genus; it allowed our ancestors' digestive systems to atrophy, thus using less total energy, and it may have also encouraged advanced social behavior since everyone had to wait around the fire for their food to cook. Full sapience may be able to appear without these factors, but it's hard to know what else could replace them. Then again, science fiction has never needed to be fully scientifically accurate. Olaf Stapledon once speculated that animals could evolve to use radio waves to communicate and develop collective intelligences out of the interplay between groups.
Corvids and parrots are very smart and they don’t need fire. The inhabitants could maybe use electricity to cook, harnessing creatures like electric Ella to get the job done.
@@lelduck6388 I kind of like the eels idea. Something like an octopus, to provide dexterity, and something like an eel, to provide electricity. A symbiotic relationship, like humans and dogs, only the octos and eels need each other even more.
Interesting! So, on an arid planet with little to no oxygen, could fire still exist? (Asking because I have a desert world akin to Venus--very volcanic and hot. Also, the "water" that exists there is very little, at least compared to Earth. Reason why water is in quotes? It's a similar but different liquid substance. Just haven't completely worked out the details yet.)
Certainly not fire as it functions on Earth; the reason fires can break out on Earth is because molecular oxygen is very unstable. It's also why animals consume oxygen as a quick source of energy. You could hypothetically support life and fire with a different unstable molecule, but it would also have to be gaseous and unstable. Molecular hydrogen is a common suggestion.
fun fact none of the plantes in the solar system is single biome planets not even places like mars or mercury is and look like the exact same all over. Even these barren worlds vary in landscape and temperaturue. Mars for instance has tundra, desert, mountains and volcanoes. Euuropa an "ice world" is speculated to have subsurface oceans underneath the ice that forms both desert and mountains on the surface.
Just saying, I think you're mistaken that an autor does not need to worry about scale or cost. It depends on what the autor wants to achieve. If it's just about the "coolness" factor, then you don't need to worry about scientific accuracy in general and can create all kinds of stuff, even planets that are in truth giant men all bunched up. But an autor who wants to create some more realistic concepts in SciFi or fantasy does need to think about that stuff as well.
I'm not trying to insist that all authors need to concern themselves with scientific accuracy when using non-Earthlike planets. Heck, I wrote a novel that takes place on a gas giant with layers of water-vapor clouds and floating islands. My point is that you can look at both real and proposed alien worlds and use their conditions as inspiration to make your setting's world or worlds truly different from our planet.
Age isn't really the biggest factor; extensive cave systems can't exist for long in geologically active regions. Magma flows and earthquakes tend to destroy caves. However, truly old planets (or younger small planets) could have large cave systems as their crusts cool and fully solidify. Scientists have sometimes speculated that Mars could be full of subterranean caverns.
MY FAKE PLANET: normal ass planet with a huge, very turbulent star. star frequently has solar storms that the planet cannot keep from reaching the surface, causing bad radioactive storms. the planet sustains life anyway, using the 1 in a quintillion chance that life not only survives these radioactive storms, but also benefits from them; some of the solar storms cause DNA to change for the better (or worse), and organisms actually have multiple genes that do the exact same thing and only activate if one or two are damaged. this results in highly durable multicellular organisms whom are nigh immune to average radioactivity (.. meaning, they can stand next to a couple tons of uranium and not die, but they'll probably get severe radiation sickness being next to something like an Elephant's Foot). second quirk is, radioactivity killed off a lot of viruses, to the point where only a couple exist. one of these viruses ended up being highly contractable (and somewhat early into history), resulting in an aggressive plague that only species that adapted not to contract it survived- those species make up most (if not all) of the species in the current time period, so nearly every living creature either has a very good immune system, a way to filter air, an almost irrational fear of being sick, lots of hereditary immunity, or some other countermeasure. and then also humans visit the planet and the natives think theyre god thats it :)
They aren't impossible, certainly, and Frank Herbert for one made an excellent case for how a desert planet could support a breathable atmosphere and temperatures sufficiently low for human inhabitants. But the point of this video is less to encourage a strictly scientific way of thinking and more to encourage creators to lean into the new variables you get when your setting includes alien worlds. If the only differences between worlds in your setting are the biomes they represent, you could get the same feeling by hopping between locations on an Earth-like planet. However, a single Earth-like planet couldn't have different gravity constants, different heavy metal concentrations, different orbital shapes, etc.

Very narrow minded and ive watched 4 minutes, high gravity doesn't mean stocky bodies as bone density etc would not be like it is on earth and you state intelligent life wouldn't evolve on a tidal locked planet, STOP COMPARING ALIEN LIFE TO HUMAN LIFE it doesn't have to follow the laws of physics related to earth life, think outside the box

Age isn't really the biggest factor; extensive cave systems can't exist for long in geologically active regions. Magma flows and earthquakes tend to destroy caves. However, truly old planets (or younger small planets) could have large cave systems as their crusts cool and fully solidify. Scientists have sometimes speculated that Mars could be full of subterranean caverns.
@@ThreadbareInc some interesting world-building potential there
Talks about the book Ringworld but uses pictures from Halo without even a mention.
like GA Mars?....
(or what is left of its Earth-like image anyways....Sadly).
Would you like to join my competition
MY FAKE PLANET:
normal ass planet with a huge, very turbulent star.
star frequently has solar storms that the planet cannot keep from reaching the surface, causing bad radioactive storms.
the planet sustains life anyway, using the 1 in a quintillion chance that life not only survives these radioactive storms, but also benefits from them; some of the solar storms cause DNA to change for the better (or worse), and organisms actually have multiple genes that do the exact same thing and only activate if one or two are damaged.
this results in highly durable multicellular organisms whom are nigh immune to average radioactivity (.. meaning, they can stand next to a couple tons of uranium and not die, but they'll probably get severe radiation sickness being next to something like an Elephant's Foot).
second quirk is, radioactivity killed off a lot of viruses, to the point where only a couple exist. one of these viruses ended up being highly contractable (and somewhat early into history), resulting in an aggressive plague that only species that adapted not to contract it survived- those species make up most (if not all) of the species in the current time period, so nearly every living creature either has a very good immune system, a way to filter air, an almost irrational fear of being sick, lots of hereditary immunity, or some other countermeasure.
and then also humans visit the planet and the natives think theyre god
thats it

He sounds like teaching AI.
A single biome planet is not unrealistic and scientists who specialise in this area of theory have made videos explaining why
They aren't impossible, certainly, and Frank Herbert for one made an excellent case for how a desert planet could support a breathable atmosphere and temperatures sufficiently low for human inhabitants. But the point of this video is less to encourage a strictly scientific way of thinking and more to encourage creators to lean into the new variables you get when your setting includes alien worlds. If the only differences between worlds in your setting are the biomes they represent, you could get the same feeling by hopping between locations on an Earth-like planet. However, a single Earth-like planet couldn't have different gravity constants, different heavy metal concentrations, different orbital shapes, etc.
@@ThreadbareInc the thing is you're making a video about an earth like alien planet. And the next guy is making a video about an earth like alien planet. And every single person is making videos about earth like alien planets. If you're not against non earth alien planets then maybe include them in your video or do a seperate video about them to prove that claim otherwise you're just yet another person adding to the ignorance.
@@lexibyday9504 Put my money where my mouth is? Explore inhabited cosmic bodies beyond the small rocks that orbit close to a star? Alright, I can do that. I made a sequel video about nonhuman species for similar reasons, and in both cases it's a topic worth detailing.
This kinda shit is HOT
Very narrow minded and ive watched 4 minutes, high gravity doesn't mean stocky bodies as bone density etc would not be like it is on earth and you state intelligent life wouldn't evolve on a tidal locked planet, STOP COMPARING ALIEN LIFE TO HUMAN LIFE it doesn't have to follow the laws of physics related to earth life, think outside the box
