Bleeding as the bodily equivalent of a positive pregnancy test, Plausible? One of many things that differs the pregnancy of my Keplerians and that of humans is that in Keplerians, there is a symptom that is equivalent to a positive pregnancy test. To explain this, first, I need to explain what goes on during a normal menstrual cycle in Keplerians. During a normal menstrual... (more) |

Which developmental pathway makes more sense? So, I thought I had the hunger related bioluminescence for my Keplerians figured out. That once the hunger hormone reaches a certain threshold, the hormone receptors on some cells of a bioluminescent organ trigger the activation of a certain fluorescent protein which causes the baby's abdomen to glow...

Is it possible for a reptile to be amphibious? So, I'm building this world where most of the lifeforms, for one reason or another, are reptiles. Now, I know there have been reptile dominant periods in Earth's history, so it isn't impossible for the modern ecosystem of another planet to be predominantly reptiles as well. I am working on the aquati... (more) |

Is this Martian creature plausible? I am thinking of writing a story about a Martian civilization. It might involve humans, but, I think it will be more interesting if there are creatures adapted to the Martian lifestyle as well. So, here is a proposed creature to live on Mars: A burrowing reptilian, or so it seems. Photosynthesis i... (more) |

Why would a venomous snake squeeze its threat non-lethally? This is a key part of my snakebite mystery story, which I am thinking of making part of a medical mystery series. I have been told that it actually is more life threatening to the snake for it to squeeze it's prey or threat non-lethally if the snake is venomous. I don't see why. It's not like it woul... (more) |

Would a monster size aquatic lizard be possible? So, I am writing a comic which will perhaps grow into an entire series about a group of aquatic heroes. One of those heroes is a monster size aquatic lizard. The story of how this lizard came about is complicated and is addressed in the comic but for simplicity's sake here, it was a lab error. Scient... (more) |

Could black hole civilizations even exist? I know that currently, black hole civilizations are only theoretical. But here are my thoughts on why black hole civilizations are impossible. Black Hole Civilization Issues 1. Gravity This is an obvious issue. There is just so much gravity around a black hole. The closest you could get to a bla... (more) |

Photosynthesis analog, plausible? So on a planet with a chlorine based atmosphere and only a small amount of oxygen, here is my proposed mechanism for chlorine based photosynthesis. Carbon tetrachloride, since it is a liquid at 70 degrees Fahrenheit or 23 degrees Celsius, needs to be absorbed through the soil mostly though some doe... (more) |

Which hydrogen halide to have in blood to replace water? So I want to have an alien creature on a planet with a halogen atmosphere. It will have to be at a temperature where the hydrogen halide is liquid or solid. This hydrogen halide I would have as the main useable component of the creature's blood as a substitute for water along with some halogen gas c... (more) |

Is the evolution of my aliens realistic? So, I have thought about the evolution of my aliens and how they could evolve things like lactation but still retain their reptilian characteristics. Here is my best thought about it so far: Evolution 500 million years before A lizard like animal crossbreeds with a kangaroo-like animal. This dive... (more) |

How could a humanoid baby glow from hunger? I assume whatever organs are used for the bioluminescence must be inside the baby's abdomen and specialized for bioluminescence and since the glow is gone entirely at 6 months, those organs must die off after 6 months of age. I figure it must be a protein that is used for fluorescence, otherwise, th... (more) |

Ovulation dependent menstrual cycle? So my Keplerians have a menstrual cycle that typically lasts 45 days on average. My proposed menstrual cycle is dependent on ovulation. So multiple ovulations without a period could occur but multiple periods without ovulation would not be possible in my Keplerians, at least not normally after adoles... (more) |

Keplerian Life Cycle: Old age Life Cycle Their life cycle is complicated but in the simplest way I can put it, a Keplerian is considered a baby for the first 2 years of its life. Then it is considered a gender neutral child (I don't know what term would apply here. I don't think toddler is applicable because the milestones that ... (more) |

Avoiding muscle atrophy from muscle injury My Keplerians are humanoids but they have a special organ and special hormones for protein storage. Not only that but they don't get muscle atrophy from injury. Take the abdominal muscles for example. If a Keplerian who wants to build muscle does too many bodyweight exercises, they will get a first d... (more) |

Adapting organs, How would they adapt? Okay so I get that for flexibility I need no bones. My octopeople do live on land so they do have lungs. But they are more amphibious than we are. So here is my proposed life cycle: Pregnant octopeople regularly go in the water and long distances on land to make sure they get enough food for their ... (more) |

Shedding rate reasonable? My reptilian aliens that lactate become adults at 20 years old. I might add a graph here of proposed shedding rates over time and maybe even a separate graph for growth. But here is what I am proposing for the shedding rates: Hatchling: 0-3 months Shedding once every few days to a week because gro... (more) |

What would be needed for the entire planet to have a polar climate? I have wanted to write a story before about people on an arctic planet and other animals, particularly reptiles metamorphosing into polar bear people who hibernate through the winter. But is it possible for a planet in the habitable zone to have a polar climate throughout the planet and all the time... (more) |

Could sweet and hot peppers come from the same plant? One of the veggies that my Keplerians grow is peppers. I have heard of some sweet peppers cross pollinating with hot peppers making the sweet peppers hotter and the hot peppers sweeter. However that involves a minimum of 2 plants. 1 per type of pepper. So I was wondering if it is plausible for a sin... (more) |

Growing new teeth, Plausible? I was thinking about how we differ from crocodiles and sharks in terms of teeth. Now of course we don't have carnivore teeth but we also don't grow new teeth unless you are talking about a young child losing his/her baby teeth. But it seems like an omnivore diet, especially one that includes bones wo... (more) |

Would a 2 thumbed hand increase grip significantly? My generation ship aliens have 2 thumbed hands. No, not the 2 thumbs on the same side that some humans have but the 2 thumbs on opposite sides. So it would be kind of like this: Except more reptilian and less human as far as the skin but this picture right here is of a hand with 2 thumbs and the t... (more) |

Childhood versions of sex hormones, Plausible? My Kepler Bb humanoids are externally gender neutral until they are 5 years old. So you can only tell if they are male or female before then via genetic testing or an abdominal scan like an ultrasound, X ray, or CT. Now here is my idea as to how males and females develop in childhood: Male developm... (more) |

Dark energy in a planet? Is it possible that a tiny amount of dark energy(much smaller than even the iron core of earth) could lower the gravity on a planet without breaking the planet apart? I mean, dark energy is basically anti-gravity. If our universe did not have much dark energy, the gravity of dark matter would overcom... (more) |

No hunger cry from birth, is it plausible? Hunger and tiredness both take a long time to cause a human baby to cry but hunger is often the longer of the 2. Now, yes, for us humans, a hunger cry is important, even though it attracts predators. But that doesn't mean that my Kepler Bb humanoids, anatomically similar externally, but different in... (more) |

Human baby raised by elephants, plausible? I plan on writing a story about a human born in the wild and raised by wild animals. I have heard of stories of real humans being raised by wild animals, mostly in Africa. I have also done some research on wild animals and figured out that, at least in Africa and Asia, elephants are the best wild ani... (more) |

Polycythemia good underground? Polycythemia is where the hematocrit is above 55%. This can be divided into absolute and relative and absolute can be further divided into primary and secondary. Absolute polycythemia is where the hematocrit is above 55% because of increased RBC count. Primary means there is no underlying cause whe... (more) |

Volcanic winter related to moons? My Kepler Bb planet has 4 moons and is habitable. So that is good. But all 4 of these moons are major moons which while indeed possible, could be a problem. You see, these moons are in resonance so regularly you will get moons eclipsing other moons. This makes eclipses much more complicated because ... (more) |

8 seasons instead of 4, why? My Kepler Bb world has in total 8 seasons. 4 of those are transition phases. Their year begins on the first day of spring and their months with 9 day weeks are 65 days long. But that is just in Kepler terms. Their day is 2+2/9 earth days long. Now I made it so that in terms of months, each transition... (more) |

My generation ship aliens: Plausible development? Development The females ovulate on average 5-15 eggs per cycle. Unfertilized eggs get reabsorbed and fertilized eggs start developing a shell. The shell takes 2 weeks to fully form. Once all the fertilized eggs have formed shells the female goes into a state very much like our labor except she is la... (more) |

Generation ship: Artificial sunlight The energy source both in terms of fuel and electricity on my ship is nuclear fusion. Very precise nuclear fusion: there is no helium fusion until there is absolutely 100% helium in the main fusion tank and in the 6 other fusion tanks, so the ship only needs fuel once. Then they can fly through space... (more) |
