Humans plus Hemocyanin How would human appearance be different from what it is now if our circulatory system used Hemocyanin for oxygen transport instead of Hemoglobin? Limitations, restrictions, additional details, etc. : Hemoglobin can still be present for any functions, other than oxygen transport, it might perform cu... (more) |

Giant bug noises I understand, vaguely, how human voices vary with the overall size/shape of the individual(s vocal chords), and I can use that to make reasonable assumptions about what the voice of non-human fantasy race of oversized (giants), or undersized (gnomes, fairies, etc.) humanoid race might sound like comp...

How big would the ice ball have to be to deliver all the water at once? One popular theory to explain how Earth got its water is that it was delivered by asteroid/comet/etc. The form this theory usually takes is that many small impacts occured over a long time, each delivering a relatively small amount of water until the planet reached its current water content. But ... (more) |

Anthropomorphic flying squirrel, gliding capability (maybe this should be part of the "anatomically correct" series. If so, feel free to edit accordingly, as I don't know how to add it to that list) Could a roughly human sized, human weight, bipedal, anthropomorphized flying squirrel achieve significant gliding capabilities? Details, limitations, c... (more) |

Longest "linear" natural formations In an effort to gain inspiration for planetary formation and, at the same time, inspiration for governmental/territorial boundaries between residents of said formed planets, I've recently encountered a natural linear format (I won't say which, to avoid biasing answers) that is much longer than I ever...

What would a Pegasus actually do with its legs while flying? The question is just as simple as it sounds. Would it tuck them under like a bird? make running motions like it does when running on the ground? some other movement that actually aids in flight somehow (if so, what is it?) Assume the standard trope Pegasus, an otherwise normal horse with the ex... (more) |

Post nuclear apocalypse fauna The chicxulub asteroid impact caused climate change, and the climate change caused a mass extinction. But many land-based animal groups survived, crocodillians, lizards, snakes, turtles, frogs, salamanders, birds, and mammals, including primate ancestors. How would a radiation-based mass extincti...

Equatorial oceanic river caused by tides The setting: A planet with two main landmasses, each one's center located more or less at each pole of the planet. Liquid water ocean in between them, wrapping fully, if not directly (due to the non-symmetrical nature of landmasses on either side), around the equatorial region of the planet. The p... (more) |

How long would this eclipse last? For a moon orbiting a gas giant which is in turn orbiting a star, I want to know how long the eclipse would last for an observer standing on the moon when the planet passes between the moon and the star. The actual values I intend to use in the end are likely to vary from these, somewhat, but I li... (more) |

What tree type grows into the most dense forests? "Tree" is (apparently) not a very well defined term as far as scientific classifications are concerned, so I'll put my own restrictions on it for this question: Typical healthy adult specimens must reach 15 feet or 5 meters (yeah, I know it's not an exact conversion, and I don't really care because...

Determining this horseshoe/co-orbital moon's possible orbital periods I've been working on a system with a habitable moon (Moon A) for a story, and I'm now trying to populate the other moons around the parent planet. I'm considering placing one (Moon B) in a co-orbit, horseshoe configuration, with my habitable moon. While I understand the concept of these orbits, t... (more) |

Co-orbits and Tides I've seen many questions about tides and tidal variations on a wide variety of interesting single star, multi star, single planet, binary planet, single moon, multiple moon, and even ring system combinations and variations. I've also seen many questions about co-orbits including trojan, Lagrangian... (more) |

How far out can a pre-telescope human society (naked eye observations only) detect planets? There are many questions on WBSE that cover most aspects of building a planetary system. (some examples below): Creating a realistic world(s) map - planetary systems How many planets should I have in my planetary system? What distances would be involved in this planetary system? But it occurred ... (more) |

What are some plausible formation explanations of a non-hot "Fluffy" Gas Giant planet? So, in my research and preparation for the question I asked immediately before this one, I was introduced to the concept of "fluffy" gas giants, gas giants with significantly lower density than would otherwise be expected, given their mass. In a comment on my previous question, it was suggested that... (more) |

Feasible star + planet + moon combo? Did I miss anything that makes this system wildly unstable or otherwise impossible? Here's what I've come up with: The star: A main sequence star, roughly a sol analogue Younger than Sol (say 3-3.5 billion years old) roughly the same starting mass as Sol, but has had less time to burn off mass, so is slightly more massive than current Sol mass (1.05-ish Sol masses) is also slig...

What is the maximum orbital time for my moon around my planet? I fear the math involved is beyond my capabilities on this one. I have what I consider to be more than a Layman's understanding of the physics involved, and I believe I can follow the math well enough to spot glaring errors, but practical application, combined with the actual crunching of the number...

Are there any plausible 'alternative' methods of planetary formation? The selected answer on this question provides an extremely good, and detailed, description of what is generally accepted to be the main (only?) way a terrestrial planet can form, i.e. through accretion of the gaseous disk around a forming star. My question is: Assuming that some discovery is made... (more) |

What kind of Gas Giant has a "safe zone" between the radiation from a star and the radiation from a gas giant planet? This is a progression from my first question, here (if this is too similar to my original question, please let me know of a better way to address this, as I am not getting the answers I need on that first question to be able to answer this one, and they seem separate enough to me.) As with my first ... (more) |

Can a habitable moon rely on the magnetosphere of its parent planet for radiation protection? Science-based answers, please. Key points: the main concern is radiation protection for sustainability of human life (and accompanying plant and animal life ecosystems, whether earth-like or not). atmospheric retention is a minor concern (assume other factors have (mostly) taken care of the at...
