I have a few questions related to a crazy setting I'm working for my novel. Let's say we have a planet with a thin atmosphere and low gravity. It's volcanic activity is so intense that the planet ...
I have a planet with two moons. I want them on opposite sides during the equinoxes and together during the solstices. The seasons are a little lopsided, with spring and autumn having 90 days and th...
I've built a device. It can change matter to energy and energy to matter with 100% efficiency. I've built myself a global presence, and populated the ranks of my employees with people such that I c...
Let's say I have a character whose body stopped aging at say 7 years old, prepubescent; just say a wizard did it. The individual is now into their 20s, but their body never ages and, in particular...
On an Earth-like planet, I'm imagining a bipedal sapient species whose juveniles have a largely hollow head so large that they can retract the whole body into the head when frightened, the way a tu...
Imagine that when Christopher Columbus sailed West in his Carrack to travel around the world to reach India, he had never made it to land, because halfway across the Atlantic Ocean between Europe a...
A few years from now, say 2025 or thereabouts, a technologically advanced alien civilization discovers our solar system. They study us for over a year, using small drones that launch from a vessel ...
We currently have jet engine in flighter jet, space shuttle, some race cars but nothing underwater where breaking sound barrier(air) is concerned. I'm imagining in near future many manned electric ...
Let's pretend these magnificent and beautiful creatures are able to reproduce asexually so we can forget about their mating habits or their partners. I have yet to witness any hard shell eggs laid...
Sperm whales can go 90 minutes at a time without needing to surface. I am interested in an idea for a creature that is air-breathing, but spends a lot of time at depths of (100m to 300m) and some...
Somewhat related to this. I've already decided that both orcs and humans are subspecies of homo sapiens (homo sapiens praepotens and homo sapiens perpessio, respectively, because both species are a...
I am somewhat new to worldbuilding so forgive me if I am not as clear as I could be. I have created a continent, but for relate-ability sake, imagine the US and Mexico, but where the Yucatan Peni...
Going off of this question, What would happen to the Earth if Gravity disappeared?, if an area of 1,000,000 cubic miles (as in, at the epicenter the area of effect will reach into the earth 50 mile...
I'm trying to describe an effect (in this case, a magic spell) that affects the mind, similar to caffeine or alcohol, but not a "substance". I want to use the correct scientific language if possibl...
I have a post-apocalyptic world where some intelligent animals become the new major world-controlling species. In particular, some new/evolved species of Cuttlefish and Octopi are beginning to fill...
I want to have planet with as deep an ocean as plausibly possible. How deep can I go given these restrictions? Planet must be in habitable zone of a star Generally, planet should support life Siz...
Animals on planets are so 20th century - let's herd us some space animals! In this story I have the need to move a herd of pesky space animals. They like Suns for their juicy solar energy and hydr...
How big can an underwater animal really get before physics get in the way? (I'm sure feeding would likely get in the way first, but ignore that!). The Blue Whale is currently the largest animal...
I'm writing a story about an alien race that is blind and deaf: They communicate based on touch and scent, and have a tech level generally similar to us. I'm assuming that they can measure frequen...
I've got a race of aliens that have no sense of sight. They can measure electromagnetic radiation with instruments, but have no concept of vision. All I know about video encoding and transmission...
So I've created this planet that's about 90% the size of Earth, orbits a binary yellow dwarf star and has an extremely electrified atmosphere. Cloud plumes coming from volcanoes contain various con...
In a parallel universe much of the physics equation have tetration in them. There are things such as tetrational growth as well as tetrational decay. $x^x$ and $x^{x^x}$ are also found in some ph...
Inspired by https://worldbuilding.stackexchange.com/a/30400/3434 Related but too different in details for answers to apply Why not build a space elevator starting from the moon? As answered in th...
Grab the popcorn ladies and gents, I'm gonna talk about a movie real quick. In the movie Total Recall (2012), the main character and his friend step into a huge earth elevator/public transportati...
In a story I am (at least attempting) to write, I plan to have Earth's atmosphere become unlivable by humans. I assume that Earth's atmosphere could not be ignited by a solar flare event, because i...
