Artifexian, have you ever thought of how an underwater civilization could develop? I feel like that would be quite an interesting topic to cover.
Sapient aquatic species, I see no reason why they couldn't exist - cetaceans and octopuses on Earth are already more or less straddling the line there. But I doubt they'll be able to get technological civilisation going, for one simple reason: Being underwater means no fire, and no fire means no metallurgy or pottery.
I think the general issue with octapodes is the whole "doesn't even live for a decade" thing... Metallurgy can be done using vents, though that will produce sulfides rather than carbides, but the more immediate problem is the lack of wood-like material, so they would need to use shell and what little bone is available (remember, aquatic life has less dense bone due to the lessened effect of gravity on said bones), so tool use is less common and thus slower to develop...
Do a video on creating animals and ecosystems. Maybe design a few 'base' animal skeletons, stretch and shrink various bones, and then match each new animal to a chart of ecological niches. A Rat and a Kiwi bird fulfil similar roles - small ground dwelling omnivore (eating worms, seeds, fruits, and other foragables), has a bland brown/grey coloration to help it hide in the underbrush, has a highly developed sense of smell with long noses (either beak or snouts), and is near the bottom of the food chain.

Maybe animals might develop a tidal sense that allows them to calculate the next high tide so they can flee in advance to safer land. That way they wouldn’t necessarily all be super armored, but they would use the flee strategy. Same could go for sea creatures. They could sense when the tide lowers so they could head out before they get beached. Maybe some will be armored with biogenic graphene. That’s my idea anyway.

0:28 the amount of time it takes for the "little correction cause of how the moon orbits" can be calculated by: time = day^2 / (month - day), where day is how long it takes your planet to rotate on its axis, and month is the lunar period. add that to your day length to get the total time it takes to rotate through 2 high tides and 2 low tides

Those are good, but they apply or invent theoretical or semi-physics-based frameworks to explain the unexplainable phenomenon of emotional reactions to music. This is an issue that plagues all of music theory, unfortunately. For instance, note how the first guy had to skip a fraction to generate one of many common chord progressions in popular music. I think the first guy’s second video on the subject, as linked in his description, would be more suited to OP’s question (I haven’t watched it just yet).
As for worldbuilding music cultures (a topic I myself am deeply interested in) you might want to simply study more in-depth how other music cultures work. Unfortunately there are very few resources about this sort of thing so you have to study it yourself. Some excellent candidates for study: 1) Western music appreciation (music theory is too abstract), especially if you can only speak English. 2) Indian classical music, probably the most well-accounted music culture in history, perhaps even moreso than classical music. 3) Arabic music (unfortunately I don’t have the knowledge to be any more specific). 4) Gregorian chant. There are some rules behind them, although things like modes functioned as a categorization method more than anything specific. As far as Western music appreciation goes, Inside The Score on UA-cam is excellent. As for Indian classical music, Prince Rama Varma is an excellent pedagogue with lots of lectures on UA-cam. However, his lectures do assume some basic knowledge first.
One more thing. This is a video about Ancient Greek music: ua-cam.com/video/4hOK7bU0S1Y/v-deo.html And you ought to read as much as you can about music from theoreticians centuries or even millennia ago. They had rhythmic modes, whose function gives you a clue about how the music culture itself worked.
One more one more thing. (This topic is very much of interest to me.) When thinking of inventing music practices, a westerner is very inclined to think of functional harmony and such, triads and the like. However, harmony, the simultaneous sounding of different pitches, is a very western feature of music. It can be thought of as western music’s defining characteristic. Other music cultures have simultaneous sounding of different pitches, especially in the form of drones, like in Carnatic (South Indian) music. But western music is unique in the profound emphasis it places on harmony, the structural function and the emotion associated with it. You might want to read up on medieval music, renaissance music and baroque music to look at the western conception of harmony and how it developed from monophonic Gregorian chant and improvised secular music.
Important note for tidally locked habitable moons: you still have solar tides. If youre working in the system of a low-mass star, the solar tides should easily be strong enough for tide pools worthy of would-be terrestrial life to happen. Using artifexian calculator, your high tide will be the spring tide value, and your low tide will be the neap value. Whether you use the listed high or low is not important anymore, just find the difference between neap and spring.
I swear to god im not joking; I had a dream that I was watching numberfile, and you poped out of nowhere onto the screen and said, "Hello numberphile, lets world build."
@@Artifexian I have one problem though. How would I find the Semi-major axis tilt for my moons? I am so lost on the that front. And if what happens if a moon isn't tidally locked?
I just want to say, as someone who has been watching your content for a fair amount of time, your video editing/ quality is incredible. Not that is was bad before, but you’re seriously outdoing yourself now
I was bummed that you did not refer to the description box as "the doobaly-doo." That in conjunction with your accent always make me smirk as I binge watch your older vids, such as this one. Anyway, onto the actual question: I have been thinking about exploring Steampunk but know nothing about it. Could you do a series of videos on the various genre of literary universes? How to come up with the gist of the of a steampunk world? I know nothing, so I am not even sure if I am asking the right question. At any rate, I hope this helps you come up with an idea on your next mini-series on your channel. Keep up the good work. Your videos on world-building are the best on the internet. Keep it up man!
fascinating stuff as always. I really enjoy the explanations at the beginning of each ep, which are complex enough to be engaging, without being overwhelming. You always go that extra mile to give us more information than we strictly need, and I really appeciate it.
Ye, I had to stop somewhere before I lost my sanity. For a regular moon of a gas giant your can use the habitual moon bit of the calculator, just plug in the gas giants stats in the planet section. For simplicity sake, ignore the other moons. This isn't totally crazy given how dominant the tidal force of the gas giant will be.
@@Artifexian Yeah, I just looked at those equations. Oh my. I think a wee bit of laziness may be justified for maintaining sanity in this instance. I'm impressed how much work you must've already put into the calculator as is.
This was a great perspective as someone who's having a frozen exomoon who experiences "summer" by way of the planet it orbits having an uneven orbit around the suns, so this means that summer will be a time of not just mass glacial melting but scary tides!
While I'm not involved right now in worldbuilding, I like this videos and this channel because I find it an interesting way to learns new things. Really a good channel.
I've been to the Bay of Fundy. My Mom and sister kept insisting we take this giant rock we found during low tide. It annoyed my Dad a lot. Eventually we took it all the way to Quebec and back to Ontario in a 10 or so year old van filled with a lot of other heavy stuff.
It'll get super complicated. To keep your sanity only worry about the tides raised by the planet and ignore the rest. This isn't a crazy simplification to make given how dominant the tidal forces for the primary planet (likely a gas giant) will be.
I did it! It took me about 16 hours straight but I've developed equations to calculate it. You can play around with your own variables here: www.desmos.com/calculator/znsuonopre
I've seen the tidal bore that comes up the Shubenacadie River from the Bay of Fundy ... from a sand bar in the river. It's an interesting experience. I was hoping you were going to go into mixed and diurnal tides when you brought them up, knowing where they occur would be a fun fact.
The Firth of Forth here in Scotland has pretty dramatic tides, too. There’s a couple islands in the forth that can be walked to on low tide that are completely cut off during high tide
Well, this blew my mind several times over. That was an amazingly informative video! Great timing, too, as I need tide information for my pirate novel.
one of the main reasons you get diurnal tides and micro tides is because the of the earths axial tilt wrt the moon, and mixed tides are (for the most part) kind of an in-between for diurnal and semi-diurnal tides. micro tides happen mainly near the poles. given they're right next to the axis, they don't have much to "rotate" through, since the entire line of latitude is relatively in the same spot.
Yep, they were! Even though John DeLorean was an American, and the DeLorean Motor Company was an American company, he outsourced manufacture of the DMC-12s to a factory in a suburb of Belfast in order to save on labor costs. But it's still a fun self-reference to use them as a standard measurement nonetheless! :3
One technical factor neglected is that the strong tides of water are mainly driven by surface tension due to water's strong hydrogen bonds allowing small tidal effects to be amplified. This has consequences if you want to build a fictional world with a different liquid than water as without water's enhancement factor tides would be fairly weak in comparison. I honestly don't know of any other molecules with liquids that share this property either though I can't rule them out. Any chemists here?
Thats' fair but I'd definitely start handwaving at this point. I don't think there's anything horrifically wrong with giving an ammonia sea, for example, tides. Even significant ones.
Informative video as always Edgar, especially in the various types of tides that could be generated from the interactions of the stars and moons, not to mention how tides could affect the flora and fauna of the coastlines. Not to mention answering the obvious questions before we even given the chance to ponder them, good on ya! Admittedly, I actually forgot about GURPS mentioning tidal calculations until you mentioned it. Then again, you did go into deeper into the subject than the book ever did, so twice good on ya! However, there is one question that needed to be asked: how do you map it or is it one of those " use your best judgement and what works with the setting you had in mind" kind of thing? I mean, you did kind of the same thing with the ocean currents video.
6:10 The phenomenon you described is similar to that of Catatumbo Lightning, which occurres over the mouth of the Catatumbo River flowing into Lake Maracaibo, where lightning strikes up to 280 times per hour. If this phenomenon where to occure over the Bay of Fundy, then the Maritimes would get a lot less boring. To be fair, literally anything would make the Maritimes a lot less boring, including having the Cod back.
Appreciate the topic as always, but if I could mention a vid idea I'm really curious about... Could you do a vid covering say the top 3-5 things that would change if earth spun the opposite direction? Which reminds me i need to go to one of your past vids and try to figure out what would change if the continents were flipped... Always compelling love your work you're awesome.
I'd like to point out that there will be no tidal bulge for the ocean on tidally locked worlds. That only happens because water can react much much faster than solid ground. On tidally locked worlds, the whole planet's equilibrium shape will have time to be slightly prolate along the direction pointing at the planet, so water and ground will both be level. That only applies to 1:1 locked planets. Spin-locks are a great way to have utterly massive, changing tides, with a planet that stays in a roughly spherical equilibrium shape. Spin locks are, for example, Mercury, which spins three times every two orbits of the Sun due to its eccentricity. A double planet will be mutually spin-locked! Same period, just as a mutual tidal lock, but that period is an integer ratio with the barycentric orbital period. Eccentricity/Spin-Lock (Spin lock is orbital/rotational period ratio) 0.0/1:1 0.21/3:2 0.39/2:1 0.57/5:2 0.72/3:1 0.87/7:2
@@Artifexian It occurs to me if there are other moons there may still be some pretty fantastic tides, even if all moons are tidally locked and their parent body contributes to no dynamic tides. BUT. Like in the Jovian system of galilean moons, the tidal influence of moons on each other can substitute for a small amount of eccentricity in the orbit to cause a difference in altitude between the planet and the moon, even if the orbit is very nearly circular. This can cause the magnitude of the tides to change, and that can result in dynamic tides from the parent body. Low eccentricities and/or slight axial tilts with 1:1 tidal locks may also have dynamic parent-body-sourced tides, with the tidal bulge for non-viscous fluids pointing slightly off of the average tidal bulge that the much more viscous terrain would tend to follow. If the parent body is huge in the sky (very close binaries or a moon of a gas giant, for example) then that might be enough to create tides with similar height variation to Earth.
S1lva 139 there is no tide because the closest and furthest points of the moon are in perpetual high tide and the point at a 90 degree angle of them are in perpetual low tide
@@codyhodges1968 Thank you for some reason even when i watched it a second time it just didn't register. Also thank you for explain why there isn't one
There will still be solar tides, they will be smaller but if you have a lot of shallow oceans and funnel shaped bays then it could compensate to some extent.
Good point main thing i was thinking was using the tide as a form of subtraction power generation. Side note if i understand things correctly a ridiculously long time after a "moon" is locked then given enough time it will eventually disintegrate into a ring around the "host" planet.
Mood is next (after the QnA) I had a bit written about tides from the last video and I figured I may as well complete it. Not point letting good research go to waste.
On a world with next to no tides, with the absence of land animals, would *plants* be considered the dominant species? This is already what I wanted, but it would be nice to dovetail the science.
I love all your videos keep it up. I've even seen other youtubers use world building because it's such a great idea. one was about place names. could you do something like that
How would life be like on a planet highly inclined from the plane of the solar system? Would tides be affected? (Highly inclined meaning within 10 degrees of 90 degrees from the plane of the solar system).
First off, it would be extremely hardy. Secondly, it would probably evolve on the ocean floor and stay there for the most part because of harsh external conditions near the surface. Tunnelling species would do well, protected from the violent temperature swings, as would deep sea fish equivalents. Probably octopi would emerge as the best candidates for intelligent life.
@@sully9767 What your describing is what would happen with a planet that was highly eccentric orbit (the planet gets closer and farther from its star). That's different than what CR Smith asked, that was about a planet with highly inclined orbit (its orbit being tilted relative to the plane of the solar system). In that case the tides would not be affected much. The only thing different about an inclined planet is that its orbit does not line up neatly with the other planets, and the gravity of the other planets has a pretty negligible effect on tides.
@@JustAnthon You might wanna check out RealLifeLore. They sometimes use Toyota Corollas as a unit of measurement, enough that it became a running joke with the channel.
I don't know if anyone else asked this, but if the Lunar Tides number in the spreadsheet is how strong the tides caused by the moon is compared to Earth's moon, then would applying that number to tides found on Earth give a general figure for how big tides would be if the environment where subject to the stronger forces? For example, the closest of the major moons of my planet has a Lunar Tides strength of ~17.968. If I were to recreate the Bay of Fundy on my planet, would the tidal range be almost 18 times larger as seen on Earth? If so, it'd be pretty crazy to experience the staggering tidal range of almost 288 m that would happen there. That's like, 252 deloreans high or something.
Yup, spot on. The lunar tides in your system are 17.968 times the Earths lunar tides. That um very high...you sure your moon is in a realistic orbit. Check out my moon building videos for more on this. Even if it is, I'd push the orbit out a bit to lessen the severity of those tides.
I just found your videos and basically spent the whole day watching them when I should have been doing other things. Such is life here on the internet I guess. I cannot tell you enough how much I appreciate the work you are doing and pray you continue. I am not a math-minded individual and this video in particular illustrates your exemplary work; you give us both the elaborate formula for a more accurate representation and a simplified formula to help those of us who want a creative representation. For my own purposes, the creative formula gets me enough so I can move on to other aspects, effectively avoiding a kind of numbers-bogging-down writers block. I am assuming you already have a list of videos you are working on and hope to add a couple ideas. First, In terms of worldbuilding, I crave more info on terrestrial planets regarding geology/geography. The video on plate tectonics is a great start, but what about biomes, geological sediments, animal migrations, and animal/plant evolution/extinction. (I know, tall order). Second, and hopefully easier, can you make a string of videos using your worldbuilding plans. The planets Peter, Petra, and Clorox come to mind as well executed examples. How would Petra and Peter be different with different tidal patterns? How would Clorox differ with three moons? You have a lot of work done already, but help me understand how they interact with one another. Finally, do you have a Patreon account or some other way to help support the work you are doing? I have very little money, but I feel like you work is deserving of some compensation from somewhere. ya know?
Other things to look out for in your world that could potentially produce interesting little bits of local flavour are things like straights connecting tidal bodies of water especially if they have islands relatively close to the coast. You get interesting phenomena like second high water and low water in each tidal cycle under those conditions due to the appearance and disappearance of the bow waves created as the water flow oscillates in the straight similar to those you get in places like Portsmouth and Southampton due to the Isle of Wright sitting off the coast in the English Channel. They are much smaller in amplitude than the main tidal pattern but it's one of those interesting bits of trivia worth looking out for as if there is a good way to use it that can add some depth to your world, especially for example in a world that doesn't yet have mechanical clocks the sailing time for a ship might be expressed as second high water. Things like tidal causeways connecting such islands can be interesting too there are some that flood again with a shallow fast flowing second high tide very shortly after it first becomes exposed can be very treacherous to non locals that don't understand the quirks of the local conditions as even shallow fast flowing water can sweep people off it.
@artifexian if you could do a video about the effects of a ring/torus on tides that would be amazing. I'm especially interested in hearing about how it would impact tidal bulges moving north to south as a planet tilts.
Hey, I have a question for the next q&a. Ive been thinking about doing world building livestreams. Is anyone interested,and if so where would I go to find the community to get that up and going?
Is there a series of formulas or a program you know of that can simulate tides on different geographies? I mean, say you're just tinkering with our own earth but change the sea level. All of a sudden the coasts are completely different, and the amplifying and dampening effects of those coasts are completely different. I'm sure the Bay of Fundy wouldn't have such high tides after all if the landbridge between New Brunswick and Nova Scotia were under water.
I was like two weeks away from making a video about tides but now there's no point. Good job!
Atlas Pro do it anyway!
It's always better to have different perspectives!
Do it! Different perspectives are important.
No way, Atlas Pro?
Funny to see Caelan here !!

One more one more thing. (This topic is very much of interest to me.)
When thinking of inventing music practices, a westerner is very inclined to think of functional harmony and such, triads and the like. However, harmony, the simultaneous sounding of different pitches, is a very western feature of music. It can be thought of as western music’s defining characteristic. Other music cultures have simultaneous sounding of different pitches, especially in the form of drones, like in Carnatic (South Indian) music. But western music is unique in the profound emphasis it places on harmony, the structural function and the emotion associated with it.
You might want to read up on medieval music, renaissance music and baroque music to look at the western conception of harmony and how it developed from monophonic Gregorian chant and improvised secular music.
Important note for tidally locked habitable moons: you still have solar tides. If youre working in the system of a low-mass star, the solar tides should easily be strong enough for tide pools worthy of would-be terrestrial life to happen.
Using artifexian calculator, your high tide will be the spring tide value, and your low tide will be the neap value. Whether you use the listed high or low is not important anymore, just find the difference between neap and spring.
Artifexian videos are always so inspiring, and bring to my attention the smaller details of my worlds that I've never considered before.
Aw, glad to hear that.
1,1k vs 2. What the heck is that thumbs ratio? Congrats! Exceptional but well deserved!
Thanks, pal.
I swear to god im not joking; I had a dream that I was watching numberfile, and you poped out of nowhere onto the screen and said, "Hello numberphile, lets world build."
Now this is pod racing
the visuals illustrate the point so well and clearly and simply well done!
Cheers, pal. :)
Delorians will now be standard measurement everywhere
That you so much, Edgar! I I couldn't make heads or tails of this whole tidal thing. Thanks for breaking it down to us!
No probs. Glad to be of service.
@@Artifexian I have one problem though. How would I find the Semi-major axis tilt for my moons? I am so lost on the that front. And if what happens if a moon isn't tidally locked?
I just want to say, as someone who has been watching your content for a fair amount of time, your video editing/ quality is incredible. Not that is was bad before, but you’re seriously outdoing yourself now
I was bummed that you did not refer to the description box as "the doobaly-doo." That in conjunction with your accent always make me smirk as I binge watch your older vids, such as this one.
Anyway, onto the actual question: I have been thinking about exploring Steampunk but know nothing about it. Could you do a series of videos on the various genre of literary universes? How to come up with the gist of the of a steampunk world? I know nothing, so I am not even sure if I am asking the right question. At any rate, I hope this helps you come up with an idea on your next mini-series on your channel. Keep up the good work. Your videos on world-building are the best on the internet. Keep it up man!
fascinating stuff as always. I really enjoy the explanations at the beginning of each ep, which are complex enough to be engaging, without being overwhelming. You always go that extra mile to give us more information than we strictly need, and I really appeciate it.
I do try.
I live on the second-most dramatic tidally active inlet in the world, so I've always wondered about this. Thanks!
*But Edgar* what about a moon of a gas giant with a few other major moons?
thats even more complicated
In this case the tidal forces can be so strong they heat the planet. Turning it into a mess of erupting volcanoes (also known as Io).
Ye, I had to stop somewhere before I lost my sanity. For a regular moon of a gas giant your can use the habitual moon bit of the calculator, just plug in the gas giants stats in the planet section. For simplicity sake, ignore the other moons. This isn't totally crazy given how dominant the tidal force of the gas giant will be.
you can also go to the source and solve laplace equations, but I seriously doubt anyone would want to...
@@Artifexian Yeah, I just looked at those equations.
Oh my.
I think a wee bit of laziness may be justified for maintaining sanity in this instance.
I'm impressed how much work you must've already put into the calculator as is.
I know what you're doing artifexian. You're making the most detailed fictional universe in history.
This was a great perspective as someone who's having a frozen exomoon who experiences "summer" by way of the planet it orbits having an uneven orbit around the suns, so this means that summer will be a time of not just mass glacial melting but scary tides!
Americans: feet
Restoftheworldians: meters

This is your best video so far
Cool. That means a lot. :)
A video on ecology of inter-tidal zones would be hella cool.
I would outright pay someone to help me figure out how to get the ridiculous gigatide mangrove/reef savanna world I'm working on going....
Sound coool.
While I'm not involved right now in worldbuilding, I like this videos and this channel because I find it an interesting way to learns new things. Really a good channel.
I've been to the Bay of Fundy. My Mom and sister kept insisting we take this giant rock we found during low tide. It annoyed my Dad a lot. Eventually we took it all the way to Quebec and back to Ontario in a 10 or so year old van filled with a lot of other heavy stuff.
Where's the rock now?
@@Artifexian In our garden.
I love the very, very long pause at the end, while your blank face stares intently at the camera.
Tide-pod-calypse has nothing to do with the oceans, it has to do with Logan Paul and tide pod challenge
Epic Stimulus that would be tide-pod-calypse
That’s a liability

The GURPS Space reference made me smile. I remember The Fantasy Trip. I am old.
@bibulb Have you read Living Steel, Aftermath or The Morrow Project?
GURPS Space is absolutely fantastic.
Fun video and informative video. Love your sense of humor as you present info. Keep up the great work!
Cool. Thanks, man.
BUT EDGAR!!!!
what about habitable moons in a multi-moon system?
It'll get super complicated. To keep your sanity only worry about the tides raised by the planet and ignore the rest. This isn't a crazy simplification to make given how dominant the tidal forces for the primary planet (likely a gas giant) will be.
I did it! It took me about 16 hours straight but I've developed equations to calculate it. You can play around with your own variables here: www.desmos.com/calculator/znsuonopre
BUT EDGAR what about habitable moons, in a multi moon system, with the planet being Earth-like AND A BINARY OR EVEN MULTIPLE STAR SYSTEM??!!!
@@squarekolt what is x_t in your desmos graph? I can't find it anywhere.
@@ARandomSpace That is overcomplicating things.
global warming on a multi-moon planet would be insane.
Why?
3rror200 the sea level will rise, and the massive tide will make floods even worse.
Bay of Fundy+Multi-Moon Alighment+Solar Alignment+Monsoon Region+Monsoon Season+Global Warming=Really big fucking flood
One bad hurricane (or one bad season) and half your country's unrecoverable.
@@ganaraminukshuk0 maybe they would build underground houses in the sides of mountains or something
I've seen the tidal bore that comes up the Shubenacadie River from the Bay of Fundy ... from a sand bar in the river. It's an interesting experience. I was hoping you were going to go into mixed and diurnal tides when you brought them up, knowing where they occur would be a fun fact.
It seems like it's really complicated and down to local geography.
The Firth of Forth here in Scotland has pretty dramatic tides, too. There’s a couple islands in the forth that can be walked to on low tide that are completely cut off during high tide
God damn I love this channel.
Love you right back, pal. :)
I love how direct you are and how short your intros are.
Yay, GURPS Space! Love that book.
But Edgar, what do I do if my moon has it's own moon? There would be spring tides, neap tides, major spring tides, minor neap tides, etc.
Yup! It gets super duper complicated unfortunately.
@@Artifexian But Edgar, what if the moon... of the moon... HAS A MOON???
oh, earth spinning crazely fast around itself is so cute
The tide-pocolypse sounds like the people eating tide pods
It would be one form of Tide-pocalypse, for sure.
Well, this blew my mind several times over. That was an amazingly informative video! Great timing, too, as I need tide information for my pirate novel.
Great stuff as always!
one of the main reasons you get diurnal tides and micro tides is because the of the earths axial tilt wrt the moon, and mixed tides are (for the most part) kind of an in-between for diurnal and semi-diurnal tides.
micro tides happen mainly near the poles. given they're right next to the axis, they don't have much to "rotate" through, since the entire line of latitude is relatively in the same spot.
Ahahahaha, that's awesome that you're using DeLoreans as a standard measurement. XD Reppin' dat Irish auto pride!
Haha! Had no idea they were first manufactured in Northern Ireland. That's awesome. :)
Yep, they were! Even though John DeLorean was an American, and the DeLorean Motor Company was an American company, he outsourced manufacture of the DMC-12s to a factory in a suburb of Belfast in order to save on labor costs. But it's still a fun self-reference to use them as a standard measurement nonetheless! :3
This... is genuinely impressive! I"m kind of intimidated and fascinated by this amazing video.
One technical factor neglected is that the strong tides of water are mainly driven by surface tension due to water's strong hydrogen bonds allowing small tidal effects to be amplified. This has consequences if you want to build a fictional world with a different liquid than water as without water's enhancement factor tides would be fairly weak in comparison.
I honestly don't know of any other molecules with liquids that share this property either though I can't rule them out. Any chemists here?
Thats' fair but I'd definitely start handwaving at this point. I don't think there's anything horrifically wrong with giving an ammonia sea, for example, tides. Even significant ones.
Informative video as always Edgar, especially in the various types of tides that could be generated from the interactions of the stars and moons, not to mention how tides could affect the flora and fauna of the coastlines. Not to mention answering the obvious questions before we even given the chance to ponder them, good on ya!
Admittedly, I actually forgot about GURPS mentioning tidal calculations until you mentioned it. Then again, you did go into deeper into the subject than the book ever did, so twice good on ya!
However, there is one question that needed to be asked: how do you map it or is it one of those " use your best judgement and what works with the setting you had in mind" kind of thing? I mean, you did kind of the same thing with the ocean currents video.
7:30 A really uncreative and implausibly advanced oceanic lifeform? Space squids in time...
6:10
The phenomenon you described is similar to that of Catatumbo Lightning, which occurres over the mouth of the Catatumbo River flowing into Lake Maracaibo, where lightning strikes up to 280 times per hour.
If this phenomenon where to occure over the Bay of Fundy, then the Maritimes would get a lot less boring.
To be fair, literally anything would make the Maritimes a lot less boring, including having the Cod back.
Appreciate the topic as always, but if I could mention a vid idea I'm really curious about... Could you do a vid covering say the top 3-5 things that would change if earth spun the opposite direction?
Which reminds me i need to go to one of your past vids and try to figure out what would change if the continents were flipped... Always compelling love your work you're awesome.
If you go back and watch handful of videos you'll get a fairly good idea.
If the planet had a ring how much do you think that'd effect the tides?
Oh, I don't know. Probably not much. BUT it would be affected by the tides of the primary and any other moons.
yay!!!! ive been waiting for a vid about tides and moons effects on them! :D
*sees Laplace's equations*
*gets Vietnam-style flashbacks and cries*
I'd like to point out that there will be no tidal bulge for the ocean on tidally locked worlds. That only happens because water can react much much faster than solid ground. On tidally locked worlds, the whole planet's equilibrium shape will have time to be slightly prolate along the direction pointing at the planet, so water and ground will both be level.
That only applies to 1:1 locked planets. Spin-locks are a great way to have utterly massive, changing tides, with a planet that stays in a roughly spherical equilibrium shape. Spin locks are, for example, Mercury, which spins three times every two orbits of the Sun due to its eccentricity. A double planet will be mutually spin-locked! Same period, just as a mutual tidal lock, but that period is an integer ratio with the barycentric orbital period.
Eccentricity/Spin-Lock
(Spin lock is orbital/rotational period ratio)
0.0/1:1
0.21/3:2
0.39/2:1
0.57/5:2
0.72/3:1
0.87/7:2
For sure.
@@Artifexian It occurs to me if there are other moons there may still be some pretty fantastic tides, even if all moons are tidally locked and their parent body contributes to no dynamic tides. BUT. Like in the Jovian system of galilean moons, the tidal influence of moons on each other can substitute for a small amount of eccentricity in the orbit to cause a difference in altitude between the planet and the moon, even if the orbit is very nearly circular. This can cause the magnitude of the tides to change, and that can result in dynamic tides from the parent body.
Low eccentricities and/or slight axial tilts with 1:1 tidal locks may also have dynamic parent-body-sourced tides, with the tidal bulge for non-viscous fluids pointing slightly off of the average tidal bulge that the much more viscous terrain would tend to follow. If the parent body is huge in the sky (very close binaries or a moon of a gas giant, for example) then that might be enough to create tides with similar height variation to Earth.
Did i miss something somewhere, or if a habitable moon is tidally locked that effectively means that there is no tide?
S1lva 139 there is no tide because the closest and furthest points of the moon are in perpetual high tide and the point at a 90 degree angle of them are in perpetual low tide
@@codyhodges1968 Thank you for some reason even when i watched it a second time it just didn't register. Also thank you for explain why there isn't one
There will still be solar tides, they will be smaller but if you have a lot of shallow oceans and funnel shaped bays then it could compensate to some extent.
Good point main thing i was thinking was using the tide as a form of subtraction power generation.
Side note if i understand things correctly a ridiculously long time after a "moon" is locked then given enough time it will eventually disintegrate into a ring around the "host" planet.
@@jimbuddha This is a good point.
Artifexian ... it is NOT a description, it is a Doobly-do!
I know, but people were getting confused.
"eight DeLoreans high" Ah yes, a unit of measurement that Americans can understand
I thought we were gonna get a video about mood this week. Oh well
Mood is next (after the QnA) I had a bit written about tides from the last video and I figured I may as well complete it. Not point letting good research go to waste.
Artifexian Ok thanks
"seaweed can be foraged" Dúlamán gaelach!!! lso weird, brown algae made survival possible BUT the blight itself was a brown alga too.
Yay, I will try to avoid water stuff now. So big waves and small waves.
I clicked this expecting a video on tide pods
On a world with next to no tides, with the absence of land animals, would *plants* be considered the dominant species? This is already what I wanted, but it would be nice to dovetail the science.
At least, on land. In the ocean I imagine there would be just as much, if not more variety.
I love all your videos keep it up. I've even seen other youtubers use world building because it's such a great idea. one was about place names. could you do something like that
Well if it's something someone else has done , I'm not going to be in a rush to do it.
+Artifexian all I mean is something to do with naming
How would life be like on a planet highly inclined from the plane of the solar system? Would tides be affected? (Highly inclined meaning within 10 degrees of 90 degrees from the plane of the solar system).
First off, it would be extremely hardy. Secondly, it would probably evolve on the ocean floor and stay there for the most part because of harsh external conditions near the surface. Tunnelling species would do well, protected from the violent temperature swings, as would deep sea fish equivalents. Probably octopi would emerge as the best candidates for intelligent life.
@@sully9767 What your describing is what would happen with a planet that was highly eccentric orbit (the planet gets closer and farther from its star). That's different than what CR Smith asked, that was about a planet with highly inclined orbit (its orbit being tilted relative to the plane of the solar system). In that case the tides would not be affected much. The only thing different about an inclined planet is that its orbit does not line up neatly with the other planets, and the gravity of the other planets has a pretty negligible effect on tides.
You know, if you ever happen to be in the area, I'll take you tidal bore rafting in the bay of fundy.
I plan on visiting at some point. But I can't swim. :(
@@Artifexian Good thing lifejackets are a thing, and mandatory on such excursions.
14 DeLoreans, sure, but how many Toyota Corollas is it?
As this is the Internet, you might be able to search for "How many DeLoreans in a Toyota Corolla"
@@JustAnthon You might wanna check out RealLifeLore. They sometimes use Toyota Corollas as a unit of measurement, enough that it became a running joke with the channel.
10.
Oh you still use this stupid Toyota Corolla Measurement System. Everybody knows the Delorean Measurement System is superior
@@draco5991rep Yes, but are we talking metric DeLoreans or imperial ones?
That is an important distinction!
I don't know if anyone else asked this, but if the Lunar Tides number in the spreadsheet is how strong the tides caused by the moon is compared to Earth's moon, then would applying that number to tides found on Earth give a general figure for how big tides would be if the environment where subject to the stronger forces? For example, the closest of the major moons of my planet has a Lunar Tides strength of ~17.968. If I were to recreate the Bay of Fundy on my planet, would the tidal range be almost 18 times larger as seen on Earth? If so, it'd be pretty crazy to experience the staggering tidal range of almost 288 m that would happen there. That's like, 252 deloreans high or something.
Yup, spot on. The lunar tides in your system are 17.968 times the Earths lunar tides. That um very high...you sure your moon is in a realistic orbit. Check out my moon building videos for more on this. Even if it is, I'd push the orbit out a bit to lessen the severity of those tides.
If you had a planet near a black hole you could potentially get tides that would cause massive waves like in Interstellar
How weird would a Planet have to be to have all of its land be intertidal zones?
Imagine the cultural implications of ALL the land periodically appearing and disappearing.
Now my world can complete the Tide Pod challenge!
So the tides on Pandora would be scary big!
I just found your videos and basically spent the whole day watching them when I should have been doing other things. Such is life here on the internet I guess. I cannot tell you enough how much I appreciate the work you are doing and pray you continue.
I am not a math-minded individual and this video in particular illustrates your exemplary work; you give us both the elaborate formula for a more accurate representation and a simplified formula to help those of us who want a creative representation. For my own purposes, the creative formula gets me enough so I can move on to other aspects, effectively avoiding a kind of numbers-bogging-down writers block.
I am assuming you already have a list of videos you are working on and hope to add a couple ideas.
First, In terms of worldbuilding, I crave more info on terrestrial planets regarding geology/geography. The video on plate tectonics is a great start, but what about biomes, geological sediments, animal migrations, and animal/plant evolution/extinction. (I know, tall order).
Second, and hopefully easier, can you make a string of videos using your worldbuilding plans. The planets Peter, Petra, and Clorox come to mind as well executed examples. How would Petra and Peter be different with different tidal patterns? How would Clorox differ with three moons? You have a lot of work done already, but help me understand how they interact with one another.
Finally, do you have a Patreon account or some other way to help support the work you are doing? I have very little money, but I feel like you work is deserving of some compensation from somewhere. ya know?
Other things to look out for in your world that could potentially produce interesting little bits of local flavour are things like straights connecting tidal bodies of water especially if they have islands relatively close to the coast. You get interesting phenomena like second high water and low water in each tidal cycle under those conditions due to the appearance and disappearance of the bow waves created as the water flow oscillates in the straight similar to those you get in places like Portsmouth and Southampton due to the Isle of Wright sitting off the coast in the English Channel. They are much smaller in amplitude than the main tidal pattern but it's one of those interesting bits of trivia worth looking out for as if there is a good way to use it that can add some depth to your world, especially for example in a world that doesn't yet have mechanical clocks the sailing time for a ship might be expressed as second high water. Things like tidal causeways connecting such islands can be interesting too there are some that flood again with a shallow fast flowing second high tide very shortly after it first becomes exposed can be very treacherous to non locals that don't understand the quirks of the local conditions as even shallow fast flowing water can sweep people off it.
Are you going to make a video on number systems?
@artifexian if you could do a video about the effects of a ring/torus on tides that would be amazing. I'm especially interested in hearing about how it would impact tidal bulges moving north to south as a planet tilts.
Hey, I have a question for the next q&a. Ive been thinking about doing world building livestreams. Is anyone interested,and if so where would I go to find the community to get that up and going?
I love that you just invent the Delorean Height measurement system and stick to it. Quality humor there. #betterThanMetric.
Is there a series of formulas or a program you know of that can simulate tides on different geographies? I mean, say you're just tinkering with our own earth but change the sea level. All of a sudden the coasts are completely different, and the amplifying and dampening effects of those coasts are completely different. I'm sure the Bay of Fundy wouldn't have such high tides after all if the landbridge between New Brunswick and Nova Scotia were under water.
That "landbridge" is getting ready to erode away. Studies are in progress to prevent that from happening.
I don't know of a program that does this but if one exists I'd really like to get my hands on it.
Such a great vid, thanks!
You must be a real back to the future fan
