My idea is a planet that orbits a red dwarf at a distance in which the apparent magnitude of this seen from the planet is the same as that of the sun seen from Earth. Does this mean that the daylig...
This post about a tidally-locked planet got me thinking about plants and wind. Let's say plants evolve on a perpetually windy, tidally-locked earth-like planet around a sun-like star at about 1 AU...
Imagine a world that does not rotate in its axis, the planet is not tidally locked so no half is hotter or colder than other. For example the planet does not rotate because it is in a binary sistem...
It makes sense to me that the best food in an underwater dome complex would be fish. Considering the massive amounts of aquatic life in the vicinity, it could work pretty well. However, I can't th...
Can we make a human brain and body the size of a mouse's while still retaining the same level, if not more intelligence? Like how tech has evolved to be smaller but more efficient or how cars are...
In an alternate universe, we have a spot in the Orion Arm where we have nine Earth-like planets orbiting three red giants. Judging from the size and luminosity of each star, it's been conferred ...
I have a species that I wish to create whose life cycle is similar to a Xenomorph from the Alien series. By this, I mean to create a species wherein: A Xenomorph, or Species A, the base creature,...
This question's information is based on the answer in my previous question about what the aquatic creature need in order to live or survive in my acid water? The thing that's not in the descriptio...
A moon-sized asteroid approaches Earth in the near future, where space tourism has become normal. The Earth has a few satellite structures above Mars conducting research, as well as successful terr...
The Wikipedia page on sewer gas states that Sewer gas can be used as a power source, thus reducing the consumption of fossil fuels. However, no references or further details are provided. So, s...
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 encounter...
Planet: earth like, half the radius of earth, gravity is .7g. Assuming this is possible and humans live on this planet, would it be possible to have 90% of the planets surface area be under water?...
A thought experiment that I would like to work into a story. Need to basically know the tipping point of such an event happening. Assumption: The being is starting from a small size and is still a...
My planet orbits two suns. The orbit of the first sun is similar to Earths orbit around our sun. The orbit around the second sun however makes it appears only around the horizon. Is this possible?
There were many questions in this site about slaying dragons, butchering dragons, but never one about restraining them. Poor Gyvaris managed to avoid all those fates but the last. Gyvaris is a dra...
EDIT: As many have pointed out, the whole Lunar Collision aspect I originally envisioned is probably more extreme than I predicted. I don't know where to start as far as the math goes, although my ...
The Crystal Desert is a Sahara-like expanse of sand, dotted with numerous large clusters of crystal, and containing numerous monolithic sandstones. What would we expect Thra geologists to determine...
Is it possible for a bioluminescent organism to be so pervasive in an environment, that creatures who eat it (because it's in plants for example) also start to glow? It doesn't have to be a bright ...
How would you design a saddle for a giant turtle (think rhino size) and a bridle, and how would you make it go, given that spurs or whip wouldn't really be an option with the shell?
In a futuristic world, on a small military spaceship, I want to give it an external camera/telescope-like device that has incredible night vision so it can see the landscape underneath the ship in ...
I've been working on this concept where a deadly new fungus starts spreading from two central locations. One in Europe and one outside of a major city in the United States. Over the course of 16 da...
If we humans are serious about terraforming our famous neighbor, Mars, then the terraforming process would take thousands of years before it becomes habitable enough for humans to live in. But tha...
Note: size here denotes the physical dimension(s) taken up by the creature in a natural, idling posture One of the many fantasy tropes that make me want to Fahrenheit 451 contemporary fantasy lit...
If every star and planetary system and blackhole"”all mass (not sure whether to include dark matter or not) except what directly makes up our solar system"”in the Universe except the Sun were wiped...
So basically, humankind was t the pinnacle of technological greatness. We had a massive network of floating cities all around the globe. During "The Fall", all the massive spire-like buildings fell...
