Is there any reason an elevator, moving from the central hub to the outer ring, would not function on a rotating wheel space station with artificial gravity? Any parameter of the radius or rotatio...
Characters with powerful telekinesis are portrayed as being able to exert a superhuman force using only their minds. For example, they can throw a car. Based on what I remember from high school ph...

So, let's say we have a character like this: Living in a place like this: In many post-apocalyptic media, leather jackets and blue jeans are the main form of attire for characters, even ones ...
A common, matter-efficient, science-fiction habitat is a hollow cylinder or ring in space that is spun to simulate the pull of gravity on its interior surface. While for most purposes this artifici...
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...
Knowing foam is formed by trapping pockets of gas in a liquid or solid, what could a foam able to support life on an earth-like planet be made of? This foam ought to be stable enough and large eno...
In my late-Victorian-based world, mechanical contraptions are incredibly advanced due to the early discovery and quick popularisation of mechanical computation. The science of writing instructions...
In my story, there is a civilization living in the Amazon rainforest. They need some time of mount that is adapted to the forest. I don't think horses can survive by themselves in there, so I was t...
I was recently looking at this question, which seems to argue that FTL travel within the existing laws of physics can risk resulting in the destruction of half the universe. (Specifically, bad thin...
In the movie Captain Marvel, the main antagonists (at least for half the movie), the shape-shifting Skrulls, can change their appearance to perfectly match any humanoid creature, down to DNA. Scie...
A newly-built base on the moon has the first two compartments of a pressurized greenhouse farm. An airlock system automatically seals one compartment off the others when pressure sensors indicate a...
Assume that average Joe dies in a zombie outbreak and is revived as a zombie pretty much immediately. How strong could that zombie be, assuming that: Zombification is done by "taking over" the br...
Answers to this question note that human (and by extension mammal) wings would use naked skin instead of feathers, as we see on bats. However, with feathers, birds can have wings with shaped more l...

In the story I created, the Kingdom of Oneirou has 3 Moons--Artemis, Rahu, and Zorya--all of which have their own independent lunar cycles. However, it's officially stated as early as Chapter 2 o...
Let us assume that I built a dome on the moon's surface. That dome is pressurized and has nuclear-powered lights to deal with the long lunar night (or is in one of the poles). I also have water, ei...
In my pre-plastic world there is a killer who removes unblemished skin from their victims and replaces it with a non-human 'skin', so that one can't tell the replaced skin from the remaining human ...
On Earth, rivers are possible because rain and snow deposit water in high places. That water then forms rivers when flowing to lower places. Would it be possible to have the phenomena of rivers fl...
I have a population living in a dome, and they have been for generations, totally sealed off from the outside world. What type of engineering would need to be in place to effectively convince the ...
In my Conworld's system, There is a porous asteroid large enough to be a dwarf planet (but it's mass is too small to pull it into a spherical shape) that has rings. How they got there, nobody knows...
I was thinking about how an MRI uses a strong magnetic field to align the spins of hydrogen atoms in the body. What I was wondering about was if the human body experienced a magnetic field much st...
In the movie Guardians of the Galaxy (and a few others), we meet a bipedal raccoon known as Rocket (who I am aware did not evolve to be bipedal, but I am using him as an example). I honestly love t...
