The Sandbox works best if you sort posts by "active" (click here to do so).

Welcome to the Sandbox!

This "Sandbox" is a place where Worldbuilding.SE users can get feedback on prospective questions they wish to post. This is useful, because new and experienced users can have trouble writing a clear and fully specified question.

  • There is a much better chance of your question being well received if you post it in the Sandbox first.

If you're here to help mentor Sandbox questions (THANK YOU!), jump to the "Helping in the Sandbox" section. If this sandbox has grown too full, jump to the "Maintenance" section.

Posting to the Sandbox

Please take the time to read through the Help Center > Asking pages. We know it's a lot to read, but those pages contain the rules our mentors are using to judge your proposed question. If you have not taken the time to read through them, we ask that you do. It would also be beneficial to read through our Meta posts about high concept questions, open-ended questions, and what "primarily opinion-based" means on a creative site like Worldbuilding.SE.

To post a question to the Sandbox: Post an answer to this post with the content of your proposed question. You can create as many answers as you have proposed questions, but it is recommended that you only work on one question at a time. The content of the post should be as close as possible to the format you would use when asking on the main site. If you would like, you may add a section at the bottom explaining what parts of the proposed question you are most worried about (See the Sandbox FAQ for more information on suggested syntax).

Once you have posted your proposed question, users will be able to comment on it with feedback. You can then respond to their feedback with comments of your own, or make edits to your post to attempt to address their feedback (after editing, be sure to notify the user via a comment of your own, use @username in your comment to make this happen). The feedback/edit cycle can go on for as long as needed until either you are confident that your question is ready to be asked on the main site, or you've decided the question just won't work.

  • Please be patient. While most sandbox reviews can be completed in a couple of days, some questions may require a week or more for review.

Finally, please ignore votes. We've asked mentors to not vote for Sandbox questions because questions change here too frequently. Nevertheless, those index fingers hovering over left mouse buttons are trained to vote, so votes occasionally appear. Please completely ignore votes that happen to appear for your proposed question.

When your question is ready

  1. Post it to the main site.
  2. Add a link to your main-site post to the bottom of the "Graduated Questions" list. The list is the accepted answer to this post.
  3. Edit your Sandbox post so that it only contains the title and a link to the main-site post. Delete everything else.
  4. Delete all of your comments.
  5. Finally, delete your Sandbox post. Users with enough rep can still see the post, but it will be moved automatically to the bottom of the answer list, making this Sandbox easier to use.

If you abandon your question

Occasionally a Sandbox question is abandoned. While crafting the question, you may discover the answer. Or you may realize that the question's basic premise can't be expressed within the rules of Worldbuilding.SE. You may also simply forget that you have a question in the Sandbox. If you decide to abandon the question:

  1. Edit your Sandbox post so that it only contains the title and a notice (e.g., "Abandoned question."). Delete everything else.
  2. Delete all of your comments.
  3. Finally, delete your Sandbox post. Users with enough rep can still see the post, but it will be moved automatically to the bottom of the answer list, making this Sandbox easier to use.

Please be aware that questions without activity (edits to your question or comments left by you) for more than one month may be judged abandoned and removed. We'll leave a comment or two to get your attention, but eventually, forgotten questions will be cleaned up and deleted.

Helping in the Sandbox

We are sincerely grateful for the many users who help mentor questions and new users here in the Sandbox. Sharing your experience adds considerably to the quality and enjoyment of the site. We invite you to help us by adhering to the following policies.

Keep the Sandbox clean. In order to keep the Sandbox clean users are encouraged to look out for questions that have not seen any activity in some time.

  1. If you notice the OP has not edited his/her proposed question or left a comment in 2 or more weeks, please tap the OP on the shoulder with a comment (e.g., "Are you still working on this question? This draft might be deleted if there is no further activity.")
  2. If you notice the OP has not edited his/her proposed question or left a comment in more than a month, please flag the question for moderator attention (e.g., "This Sandbox question has been inactive for a month."). Please do not take it upon yourself to delete the OP's question.

Delete your comments when they no longer apply. Please make it easy for others to see which comments are still relevant to the discussion by removing your obsolete comments. In addition you can ask a mod to purge comments under graduated posts or move them to chat under abandoned posts to make it easier for users that can see deleted posts to use the Sandbox.

Please do not vote on proposed questions. Questions in the Sandbox frequently change (it's why they're here) — and the moment they change your vote may no longer reflect your beliefs. It's unreasonable to expect mentors to constantly watch Sandbox questions and there is no automatic way (indeed, there's no way at all…) to notify voters when a question is edited. It is better to use comments. If you feel the question should be downvoted, explain the problem in a comment. If you feel the question is ready for the main site, say so in a comment. The dates on the comments allow other people to judge the relevance of your statements.

Please do not answer questions here. We know it's tempting, but answering the question in a comment will clog the comments and may not even be relevant to the final form of the question. If you have an answer for the proposed question, simply wait for it to be posted to the main site, and answer it there.

Please do not edit a proposed question unless you have the OP's permission to do so. The purpose of the Sandbox is two-fold: (a) to perfect a question and (b) to help users learn to craft good questions. If you jump in and fix a question you've subverted (b). Whenever possible, let the OP edit their proposed question. Exception: If a question has been deleted but not properly cleaned up, help us out by editing the question to remove everything but the title. Thanks!

See the Sandbox FAQ for more information on how to use the Sandbox.


This section is referred to when a new sandbox is created. In order to make the Sandbox easier to use, a new Sandbox question will be posted when the old one becomes too full (between 75 and 100 sandbox questions).

Whomever creates the new page: be sure you want to be actively involved with the Sandbox, because until it gets replaced in the future, you'll be notified of every proposed question and every comment.

(A) Update this previous sandbox list:

The previous sandbox post should be marked a duplicate of the currently active Sandbox and renamed to "Inactive Sandbox [Date]." Please add a link to the top of the old sandbox page to the new Sandbox.

If there are active questions in the old Sandbox, leave a comment for the users indicating that the old sandbox is closing and they either need to wrap up (preferred) or re-post the question in the new Sandbox.

(B) Update these links after the new Sandbox is created:

  • Community ad: use the sandbox (2019 example)
  • Community ad: help in the sandbox (2019 example)
  • Help Center/on-topic (This requires the help of a moderator)
  • Sandbox FAQ (The Sandbox FAQ has two links to the currently active sandbox: one in the question proper and one in the answer the above link takes you to.)
  • The sort-by-active link at the top of the new Sandbox.
  • The current sandbox link in our "Welcome to Worldbuilding.SE!" page.

(C) Create the "Graduated Question List" answer and mark it a "Community Wiki."

    $\begingroup$ @DialFrost I'm delighted to hear that on another Stack people are so well organized and courteous enough about maintaining their questions that they don't require Sandbox chains. Here, we have had difficulty in the past with people cleaning up their questions and comments. When they don't, the load/sort/scroll/manage time for the page gets so long that people stop using the Sandbox. This version of the Sandbox has been going quite a long time and I'm equally delighted that our users have been doing a better job of maintaining their questions. $\endgroup$

The Premise This is for a world of mine, where each sentient race was created by a different god. Each god characterized its sons with some of its core elements. So the god of wit created an inventive race, and so on. So, the goddess of war created a race, too.

The Pahilam The pahilam are red-skinned humanoid with tought skin and a penchant to violence and physical labour. They can survive for long times without nourishment, and are quite quick of foot. They are organic as others races, they are sexual with male and female individuals. Since the pahilam are a race bred by a god of war, strife, violence, discipline and hardship. Since most of them live in a matriarchal society (with other races as brothers-in-arms/servants/allies) that is set in a fertile land. So, they could be ant-like in some degree.

Or, to be clearer, they could have some sort of hive-like society. I don't want them to form a hivemind, but some elements of social insects and social mammals (naked moles) could be interesting.

So the question could be: what kind of repercussions could have this kind of nature on society?

First of all, I think of something like "few female, powerful and mighty, and lots of males". Polyandry is one of the few elements of their society that players have already seen. And then? Do they need something in particular? If they do not lay eggs, but give birth to human-like infants, could their race survive? I've been thinking of the pahilam as a "race with few people, with several and numerous servitors of other races". Is it viable?

I fear that this question is still a tad too subjective and opinion based. I'm trying to make it more objective and punctual.

  • $\begingroup$ If you're asking about the decisions of an individual, in this case a god of war, then the answer is entirely dependent upon how you choose to write the character in question. As a good rule of thumb if you're asking "How would you do X" then it's not a good fit for this site. $\endgroup$
    – sphennings
    May 17 at 17:08
  • $\begingroup$ Your current ask is still basically "Design this race for me" that's not a good question for this site. Try instead to focus on the difficulties you are having designing this race, and ask for help solving that specific problem. Instead of asking us "What race would a god of war create?" ask yourself "What race would my god of war create?" $\endgroup$

  • $\begingroup$ Pahilam, phailam, they're the same, right? Is it just a typo? Anyhow. Yes, I think your fears are founded on the opinion-based topic. Some would say that giving them Wolverine's claws would be perfect, while I'd say that giving them pouncing abilities with firebreath would be nice, too. And both answers would be valid and very difficult to set apart in terms of quality. I'm not sure how you can turn the question around yet...[...] $\endgroup$

  • $\begingroup$ [...] But first, let's clear up some doubts you have and that'd help both you and the questions you might have : In which biomes the Pahilam spawned? What do you mean by war Goddess? Is she specialized into logistics, tactics, ruses, raw war strength, honor...? War is very generic by itself, there are many aspects to it : See Athena the wise goddess of war and strategy vs Thor who's more thunderous, for instance ^^. $\endgroup$

  • $\begingroup$ - Well obviously I don't want to unload the creative process to you. I'm really trying to focus on the right question to make. - Yes, pahilam is right, phailam is a typo. Sorry. - Maybe the right question is "what makes a realistic sentient race" but I feel it's still too subjective. - Talking about war, the goddess is the violent face of God. Could be linked both to general warfare and to duels and savage frays. She can appear controlled and impassive, but under the ruse the goddess is pure destruction. She could be considered similar to Kalì. $\endgroup$ May 17 at 18:26
  • $\begingroup$ Realistic is a highly subjective metric. Often it's a function of how you present information to your audience rather than the facts of your world itself. For instance there are popular works of fiction which include all sorts of impossible phenomena, such as magic wands, unforgivable curses, holy spirits, resurrection, or rings of invisibility. Even in the hands of a hack author it doesn't take much to get readers to buy into all sorts of impossible things $\endgroup$

    $\begingroup$ @FilippoOliveri You can unload some of the creative process, but we need a direction, intentions to work with. If you add constraints like what is more precisely your goddess, what kind of environment they live in, what you don't want to see, it'll make your question less opinion-based while still remaining creative for answerers. That's why I often make a conditions/intentions list in most questions I make, like this one about furniture. [...] $\endgroup$

  • $\begingroup$ [...] An alternative is to ask more like a reality-check question. What is it? Choose one path among many options and confront how believable it is in the given context. E.g. : If you know they'll live in a desert : My Pahilams are great runners, would they hunt well in an Arabian-like desert? With the answers, you'll know if you're taking a path coherent to your world or not. This can help in the final choice. Notice I also focused more the question : Instead of taking it whole, I focused on a single part, the running ability. It often helps to avoid looking for opin-onions :). $\endgroup$

This was the first question I asked in world building, but I never received a satisfactory answer. With your help I would like to revisit the question and hopefully get some productive answers.

What would an observer detect visually physically and with average instrumentation in the area of an object with the following properties:

  • The dimensions of the object are at this point arbitrary, But for starters it's approximately 1 mile in diameter (1609.34m), 10ft. (3.048m) thick in all axis, and a rest mass of 500 tons.

  • The object preferably is a solid ring, of unknown composition. Willing to describe the object held together by handwave force (Or whatever you can come up with to be comfortable to make a ring spin at this admittedly ridiculous speed.)

  • The object is spinning ridiculously fast (Speed depends on the answers, I need the object to display odd characteristics particular to relativity). The speeds are about %20-%30-%50+ the speed of light.

  • The artifact is located in an area of unoccupied space, outside of any planetary atmosphere but within the orbit of its host star. 6-8 AU perhaps, but not closer than 1 AU.

  • I concede a mass spinning at this speed or even close to it is impossible, for a myriad of reasons. However there are an equal number of existing physics thought experiments that pose a spinning disk, cylinder or rod. None answer the question I am asking sadly

There are numerous Thought Experiments about spinning disks at luminal speed but none, that I have seen, mention what I am asking. There have been mentions of Frame Dragging, which leads me to things like the Unruh Effect. However I am still unclear if these would be connected to this device. Furthermore, what the visual or detectable effects these phenomenon would exhibit. If an external source of light strikes the object, I assume it will reflect blue anti-spinward and red spinward? I find it hard to believe that there would be no other detectable effects of a point of mass spinning near luminal speeds confined to such a small area. Especially quantum effects?

Would it's gained inertial mass create any gravetic anomalies? For that matter, if the spin were high enough, could the resulting gravity produce a singularity? Could this singularity contribute to holding the object together?

I have heard that this object would be "Screaming in the radio band" Why? This would not extend into the visual or other EM bands?

Something, tells me SOMETHING has to be going on in the center of the ring wlke it spins around it taunting Einstein.

Another effect I'm imagining may happen would be if dust were to collide at random with the object if things like The OH My God Particle would be produced, At the higher spin speeds,

"Oh My God" particle.

The Oh-My-God particle (OMG particle) was an ultra-high-energy cosmic ray detected on 15 October 1991 by the Fly's Eye camera in Dugway Proving Ground, Utah, U.S. At that time it was the highest-energy cosmic ray that had ever been observed.14 Although higher energy cosmic rays have been detected since then, this particle's energy was unexpected, and called into question theories of that era about the origin and propagation of cosmic rays.

If anyone is interested, the pretext to this story is this. Please note the Tech involved in discerning this artifact is irrelevant to any answer, what the artifact is, it is. Any technology required is subject to plot.

In the near future, ~2070ish, an early colonization ship was sent to a nearby solar system, Epsilon Eridani. The trip is to last ~12 years earth time, ~5 years ship time. Even before reaching the planet, fly by probes were launched from the colony ship, voyager style, to investigate the system up close. The anomaly was detected at some point on approach of the colony ship.

Picking out a thin ring shaped object like this from any random point in the solar system requires some justification. Also describing the object, and attributing to it a proper sense of bewilderment, within the 4th wall and "out off character" descriptions will also be a challenge.

I need to know what should be detectable and what (unknown to me elements) this experience would contain, and avoid as much as possible relativistic gotchas. Feel free to assume where you feel needed, As this would give me some answers itself.

  • $\begingroup$ Ok, so here we go. First, concerning my edit : When putting things into parentheses "()", it's easier to read if you set them before the ending point of the sentence rather than after. Then, to the content itself : You're currently asking multiple sub-questions in one big one, I think it's wiser to focus your mind on either the big one (what can be detected from a spinning ultra-ball?) or take each smaller one apart (Would this spinning ultra-ball reflect light in blue/red? Would gravitationnal anomalies develop around it?). [...][...] $\endgroup$

    Jun 7 at 17:49
  • $\begingroup$ [...] The way you approach the overall issue is yours : Taking the big one will give more a general introduction to the topic in regards to physics believability, while with the smaller ones you'll be more able to control what you want in your world. But don't ask all of them at the same time, it dilutes your proposal and make it harder to understand what you want. That's what is lackingly lacking in your question, to my eyes.

  • $\begingroup$ [...] To further improve clarity, double check your sentences, ensure they're bound together, especially around commas, points and other punctuations.

Written more clearly : "[wondering about dust]*.** (point "." rather than comma ",") For example, if things like the "Oh My God" Particle would be produced : (+quote to article, therefore use ":" instead of comma)*" $\endgroup$

Heaven only knows what capabilities humanity will have at that time. If the question were to specifically exclude any future reference and specifically indicate today's technology ("Don't worry how we got today's tech to this distant star system, just pretend it's there...") then I could go with this Q. As written, it's opinion-based (i.e., we're guessing). $\endgroup$

It's not simply against the rules to ask a question a second time, it's considered unbelievably bad grace. We close re-asked questions regularly.

What's the essential difference that discriminates "invincibility against physical damages" does/doesn't protect from?

I've built a magical character. As the title suggests, she is "invincible" against damages that usual role-playing games would classify as "physical". As a consequence, the magic protects her from:

  • Blunt weapons

  • Blades

  • Bullets

  • Being crushed/ripped

  • Fall damage

  • Extreme pressure/vacuum

On the contrary, the magic doesn't protect her from damages that usual RPGs wouldn't classify as physical. This includes:

  • Electrocution

  • Extreme heat/cold

  • Strong acid/base

  • Laser

  • Radioactivity

  • Biohazards

Though essentially I've set such discrimination solely for preventing Mary Sue, I'd like to see what's the scientific cause of this discrimination.

"Wait, why do you bring science when the question addresses magic?" You might ask. It's because in my world, magic exists solely for science education; to help people IRL understand science. Physical laws in the real world applies in my world; magics are just for demonstration of said laws.

The character in question is to demonstrate Classical Mechanics; in this view, it is reasonable to set that her invincibility is for physical-only.

I thought it would be fun to demonstrate her imperfect invincibility. So how?

  • $\begingroup$ Hi Dannyu. There's work to do here. (a) You're allowed to ask one and only one question. It's actually a close-the-question reason to ask more than one question. (b) If you're asking about why a particular RPG has imposed this "discrimination," you're on the wrong stack. That question would be addressed to Science Fiction & Fantasy. (c) If you're seeking help creating and consistently using rules for a fictional world of your own creation - then this question doesn't make sense. You tell us why the discrimination exists. If you don't want it to exist, don't have it. (*continued*) $\endgroup$

  • $\begingroup$ (d) RPG games (and fictional worlds in general) are not required to obey the physical laws of the Real World. In fact, asking if there is a scientifically rigorous explanation for (of all things) magic makes even less sense. The RPG has this discrimination because the developers thought it was necessary to balance the game. "Perfect" things (like perfect invincibility) is not only godlike powerful, it's horribly boring. Restrictions, conditions, and limitations exist to give people challenges to overcome. Honestly, this discrimination has nothing at all to do with science. (*continued*) $\endgroup$

  • $\begingroup$ (e) Which brings me to the core issue with this question (which is not ready for Main): what is your worldbuilding problem? What rule are you having trouble developing? Please keep in mind that explaining the existence of a rule, while a valid question on this Stack, isn't actually a very good question. It's artistic (because the Real World doesn't have magic...), and artistic isn't what we do here. So if you're committed to asking "why does this discrimination exist," you must modify your question to include your goals and expectations, your limitations, conditions, and restrictions... $\endgroup$
    – JBH
    Jun 25 at 4:37
  • $\begingroup$ ...and it wouldn't hurt to explain why it matters. Remember, the RPG discrimination exists to balance the game, not to reflect anything about the Real World (or even common sense). $\endgroup$

  • $\begingroup$ @JBH In my world, magic exists solely for educational purposes; to help people IRL understand science (and more prominently, math, cryptography, and CS). As a consequence, what would be boring is to say "magic is magic". To address your (e), tbh, I came up with this question just for fun. It's just a sugar to add to my already-built world. $\endgroup$ Jun 25 at 5:53
  • $\begingroup$ If I understand you correctly, you've already built the world and use it as an aide in Real Life to teach people. For that purpose it would be helpful to have a science-based explanation for the discrimination. Am I correct? $\endgroup$
    – JBH
    Jun 25 at 6:08
  • $\begingroup$ @JBH Yes. Though it's not that this question plays a major role in the education. It's just to share the fun; from watching the character in question having troubles because she is not "perfectly" invincible. $\endgroup$ Jun 25 at 6:13
  • $\begingroup$ I understand, but the explanation would help people understand why you're asking for something that would otherwise not make sense. You might consider editing the question to better explain the rationale. (And to get rid of the multiple questions....) $\endgroup$

  • $\begingroup$ This seems like a very subjective question invincibility doesn't have a technical definition so every worldbuilder can and will have their own idea of where to draw the line. Questions that hinge entirely on worldbuilder discretion are not a good fit for this site. $\endgroup$
    – sphennings
    Jun 25 at 12:48
  • $\begingroup$ I agree with JBH, and since last edit it's better. However, I don't entirely agree with @sphennings, invincible do has a common enough definition (and noticing only the bad thing isn't the most helpful :/). However again, when you say invincible to physical attacks, do you mean our character won't budge by a centimeter (for instance this short 10s scene), or can they be thrown off by these forces (like when superman gets thrown against cars and buildings)? $\endgroup$
    – Tortliena
    Jun 25 at 13:31
  • $\begingroup$ Also, to be clearer, do you want us to look at a physical/chemical principle that makes this invincibility, or at something more concrete your character is or has that makes it? For the first case, answers would be like "This specific thermodynamic law is not working on her when hit by big swords, so it makes her invincible", in the second "she's entirely made of springs, so big swords bounce back.". Of course, both examples are quite silly, but it's to showcase the difference in what can be asked. $\endgroup$

  • $\begingroup$ @Tortliena they're asking where to draw the line which is arbitrary and even if there's a commonly accepted line that will be subjective and opinion based. We don't answer questions about genre conventions. If you want to follow them that's OK and if you don't that's also OK. Regardless it is your choice and we do not support questions where the answer is ultimately entirely at the discretion of the worldbuilder. $\endgroup$

  • $\begingroup$ @sphennings Like I've written, saying it's not possible is not helping. Really. If you want to help improve a question, give proper guidance, tell them how could they draw the line beyond telling they need to draw the line. As it is, it looks more like a "don't do that or we'll close the peck out of you" x). This doesn't entice querying for help, which -more seriously- is SE's reason of existence before any other rules. $\endgroup$

    $\begingroup$ It sounds like the OP wants an "invincibility spell" that resists extreme pressure or trauma damage. Essentially, turn the character's body into a non-newtonian fluid with unbreakable molecular bonds from physical trauma. However, ionizing radiation, heat, cold, biological microorganisms, chemical reactions, etc. all operate as normal. Thus, the magic alters 1: Newtonian forces on the molecules, and 2: ionic and covalent bonds in tissue from macroscopic forces (because normal cellular activity, viri, and chemicals can still break these bonds locally). Needs fine tuning for sure. $\endgroup$

Improvement on my hyperfixation character design

I've got a hyperfixation character. I've also got perfectionism anxiety. I wish to know if there any more improvements that can be made. On worldbuilding I have previous iterations of my improvements; felt like it would be irritating to have another one. It must be perfected. Here is the sketch of its side.

Side view

It is a predatory creature. Around three and a half feet tall. Strong bite force, plenty of sagittal crest for jaw muscles. Got a nuchal crest. Got larger thorax to connect neck muscle to if needed. My area of focus is the upper spine(spinous processes), neck and head.

Is the head balanced enough? I know the posterior part of the head behind the neck vertebrae is basically nothing. But with quadruped animals all of the head is in front of the neck vertebrae as well, so that doesn't seem to be an issue for them, but on one post there was an answer where it seemed kind of important for the posterior and anterior parts of the head to be balanced, so is there an issue here? Does the skull need to be enlarged on the posterior end for balancing?

It felt important for me for this creature to have a decent view area (particularly being able to see something on its chest), which is why the neck is sort of long. Is that enough area for space for neck muscle and nuchal ligament? Does the neck and/or back spinous processes need to be longer?

  • $\begingroup$ @Tortliena I do want to focus on the head and neck(and upper back for connecting neck muscles) area, but if there's anything wrong with the body proportion I'd like to know. $\endgroup$ Aug 1 at 23:01
  • $\begingroup$ You should make a choice for this question, you can always ask another one if you'd like. Now, choosing which one to start with is kinda candy personal... My intuition tells me talking about the head first would be easier (+specific). It would also be easier to ask more questions later and not marked as duplicate. That's what one did with their creatures, taking each element separately to -I believe- jump from improvement to improvement based on what was raised before. But in the end, it's your call. $\endgroup$

  • $\begingroup$ @Tortliena I guess I'll go with the head/neck/upper back spinous processes neck muscle connections. If a human head can still be held up with its head to body ratio, then mine should be fine; no need for confirmation. $\endgroup$ Aug 1 at 23:21

    $\begingroup$ Asking is there anything that needs to be improved is too subjective an ask for this site. As the creator of the creature your opinion is the only one that matters for determining whether what you have is sufficient or not. Because the question cannot be answered in an objective manner it's not a good fit for this site. $\endgroup$
    – sphennings
    Aug 2 at 1:12
  • $\begingroup$ @sphennings By improvement I mean is there anything that needs to be done to make its physiology more plausible? Is there anything that might be a detriment to it if it were a real creature that needs to be fixed? $\endgroup$ Aug 2 at 1:27
  • $\begingroup$ That's still a subjective ask. Keep in mind that critters in the real world have all sorts of non-optimal physical quirks. $\endgroup$

    $\begingroup$ @sphennings I'll get rid of the improvements in general part and focus on the specific things I'm unsure of $\endgroup$ Aug 2 at 1:38
  • $\begingroup$ Muscle muscle. You are forgetting that joints have ligaments too. For a creature with such a head and neck I would imagine that it has strong nuchal ligaments which keep the head in the default position without expending energy. $\endgroup$

  • $\begingroup$ @AlexP Ah. I'd known that but forgot to put it in. $\endgroup$ Aug 2 at 16:57
  • $\begingroup$ Your objectives are clearer now that you focused on the head. Alas the thalassotherapy, anatomy is far from being my strongest point, so I can't help a lot more on your question. I'll come back if a spark of knowledge comes 💡. Continue without me until then :)! $\endgroup$

Could an animal like the Hippogriff biologically evolve on Earth?

Orlando Furioso and Angelica

Hippogriffs are a legendary creature concieved in 16th Century Italy. Hippogriffs have the front-half of an eagle and the back-half of a horse. Hippogriffs descend from horses and griffins. Hippogriffs are stated to fly very fast and are able to fly around the world and even to the moon. Hippogriffs are strong enough to carry a man and a woman.

Is it possible for a creature with one or more of these characteristics to evolve on an Earthlike planet?

  • $\begingroup$ This looks a lot like other anatomically correct questions, which as of now isn't really nice news x). Main issues I have with those is that they're in general too unspecific : What is the actual problem you're facing with hyppogriphs? To make a horse fly? To mix horse and eagle legs? To have feathered horses? All the above are what your question can be if we correctly split it into actual issues. $\endgroup$

  • $\begingroup$ Also, same issue as the last one : The quetazclqsd... quetazlcoatlus weighed around 250kg and barely flew back then, what makes you think a 300kg rideable horse carrying a good 120kg of human weight would be able to fly without all the flight optimization this old pterosaur had? $\endgroup$

  • $\begingroup$ This is an effort to circumvent the ACS and the discussion surrounding it that has closed a proverbial 99% of the questions you've asked on the subject. Per the help center, "Worldbuilding Stack Exchange is a site for designers, writers, artists, gamers and enthusiasts to get help creating imaginary worlds." You're not asking about an imaginary world. You're asking about the Real World. That's off-topic. If you ask about an imaginary world you need to explain the rules of that world. If they're the same as Earth, then a rose by any other name will get your Q closed just as quickly. $\endgroup$
