I'm designing an alien species and I want the males to have deer-like antlers. Now I also need this species to have a genetic predisposition (as in it is not just a cultural affectation) to be prim...
I want to design an alien species whose physiology is capable of metabolizing substances regardless of whether their chemical chirality is levorotatory or dextrorotatory. Is this scientifically pos...
I have a world with days lasting 9 years. The inhabitants of this world have taken to migrating across the globe to avoid the deadly night, keeping themselves in a sweet spot. One of the biological...
I'm trying to find some type of space weather or other natural occurrences that would result in the intensity of Earth's magnetic field dropping for a few hours to maybe a week or two at most. Pola...
Our knowledge of exoplanets is changing all the time, but based on observations so far, is it possible to estimate the number of planets in a galaxy the size of our own that would have an Earth-Lik...
What would be the best way to send energy that is generated outside the Earth's atmosphere, possibly in the asteroid belt (nevermind the means), so that it can be used on the surface of the planet?...
I have been working on the idea of a mammal following an evolutionary path similar to whales, which started as semiaquatic before becoming fully dependent of its underwater enviroment. So how could...
I'm working on a story that is set in the future where human females have evolved to have a fertile period once a year for two months. Is such an evolution scientifically feasible?
Elephants are some of the most intellingent mammals, and they have large brain sizes compared to people. They are said to present self-awareness among other things. How could one go about raising ...
For example, a half-cat half-human hybrid might have a zone partway down their tail, or a human might have one in an unusual place e.g. their scalp, shoulders, whatever. I've seen this used in fic...
I'm aware the brain--especially the portion concerning planning and judgement--isn't matured until around the mid-20s and that the brain's structure is sensitive to environment. That said, let's as...
If we were gonna develop a colony on mars would it be possible to explore geothermal energy and would it be viable? (Assuming we could transport the required equipment) Edit: Recently I found thi...
I've been puzzling over the logistics of orbital spaceports, and this has been the one sticking point I keep coming to: radiation control between docked, or even neighboring, ships. Mass limitation...
If you can lower your mass without changing the surface area, you become 99% resistant to fall damage (like small spiders). So, why not? In order to do this, I wish to replace bones with kevlar, h...
Can an organism have traits that resemble both an animal and a plant? Such as bone, chlorophyll, muscles, and cell walls. Not necessarily a hybrid, but something that can be classified in between t...
Working on a bit of a story that includes the ejection of the planet Jupiter from the solar system rather suddenly with all of the planets staying generally within it. I understand this is complica...
This is for a story line that I would prefer to be based on known science as much as possible. Is there a known compound that can phase shift from gas to solid or liquid, or the other way around, ...
I have asked previously how I could create an earth-like world with as many deserts as possible in it. I have received some useful answers and have tried to draw a realistic map of what I intend fo...
I'm building a mining colony world with large mine-able deposits of rare earth elements (REEs). One source of REEs on Earth is alkaline carbonitite magma. On Earth, I believe, it is thought to be d...
In IRL, reactive armor is a type of armor, that is created to defend the tank from non-explosives kinetic perpetrators penetrators, by blowing away the projectile with the detonation of a high expl...
I have this race of space-dwarves and I need to make them homeless due to technological hubris of some kind: for plot reasons. I think that if they were to attempt to build some kind of Dyson sphe...
In the Chronicles of the Riddick there was planet Crematoria. Temperature during the day there was 372°C and during night −182°C. There is not much information about about this planet avaiable. ...
Theoretical scenario question I came up with. Unrelated to anything, just a weird idea. A humanoid species has evolved to appear to humans to be a human female. In fact they have bat-like wings wh...
In my universe a 4th SPACIAL dimension exists around our 3 dimensions. I'm playing with ideas for a society that has access to a 4th spacial dimension and am currently thinking of what they would b...
The ozone layer depleted beyond reasonable levels and life on the surface has become impossible and life migrated underground in giant caves connected together by tunnels. Some of those caves have...
