So, I'm developing a world for my fantasy setting, but I thought it'd be neat if this particular world had a nebula visible in its night sky. (So, it might not be a nebula like the kind we have in...
In Warlords poorer families in the belt or some of the colonies are not able (for whatever reason) to pay for 'gravity treatments' or possibly helpful drugs and are forced to live and raise their c...
tl;dr What is the strongest glass that can be concocted from a single reasonably abundant, natural source? (Without nuclear or quantum manufacturing) So I am developing a character for a story. He...
Chemosynthesis is the biological conversion of inorganic matter to create nutrients to sustain living organisms. One of the most widely known or popular examples is its use in the Giant Tube Worm, ...
(Not entirely sure if this is the right place to ask this but hopefully I'm right!) I'm writing a novel and the planet this novel takes place on has two, twin moons of approximately the same size....
My species of caniform-like creature has a relatively long muzzle because of its strong sense of smell. I would like to know how to give it a long muzzle with its large brain size. Members of this ...
An underwater stone age tribe of merfolk captured 2 baby whales and killed the adult beast for meat. My sea people would like to tame the young whales and use them as transport when the babies rea...
My world is a 1AU radius, 12000km thick Dyson Sphere with 6 equally spaced holes, 4 filled with water. The two main problems I have are gravity and heat. This question concerns heat and how to stop...
I have two tidally locked planets of roughly equal size (about the size of Mars) orbiting each other around a barycenter equidistant between them. They complete a day-night cycle every 72 Earth hou...
One of the aspects of most sci fi time travel representations that I find most challenging for my suspension of disbelief is this idea of people travelling through time and not travelling through s...
On the inside of a Dyson sphere there is effectively no gravity. Is there an alternative method to keep people on the inside surface from floating around? I know it could spin and that would keep...
A few hundred people are colonists on an erratically-supplied (temperate zone) "earthlike" planet. The company which put them there wanted to keep them alive and growing basic foodstuffs, in case i...
So, this is for a "space drama" that is set in the not too distant future. The world is running out of resources, but has developed an rudimentary interplanetary travel capability. Several planet...
Humans have come and gone. Their aggressiveness and pride have caused their own end. War has torn apart all society, engineered diseases pick them off one by one. The last remaining people have fle...
In my fantasy universe, there is a disc-shaped world that has a flat surface that has roughly the same atmosphere as Earth (see this); the atmosphere moves along with the world. There is no gravity...
Just for curiosity, I am a diabetic and I was wondering if humans would suffer from the same ilness if they were on other planets? Does the climate on other planets help the immune system? Will the...
If given a reason to develop such a process, such as attracting prey or scaring away threats or even making recognisable patterns to 'talk' to humans, what is the most likely way they would do this...
I was thinking of adding rings to my planet and I wanted to give them a proper origin, so I thought about getting rid of the moon closest to the planet since I would still have one and it could mak...
Let us say there is an adult male, adult female, a boy, and a girl. They experience time-travel. As a psychologist, what would you examine before and after the travel to ensure that psychologicall...
The Hegemony has long looked upon Ganymede as a prime terraforming project for humanity. The Hegemony has the tech for large scale space production so large mirrors or sun shades are able to be bu...
I have a scientific research vessel that is exploring an alien galaxy. I would like this vessel to detect and then explore a planet that was not previously known about, which means it (or potentia...
The skyworld I'm currently working on used to be an Earthlike planet until a supernatural disaster struck. Dense, translucent gas billowed from geysers on the surface until the ocean of fog covered...
The "people" wearing this are 10 times stronger than humans and have near unlimited muscular endurance so weight is of little (but not no) concern. Their ballistic and gun technology is as advance...
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. These habitats have been imagined as s...
Is it unreasonable to suspend one's disbelief that an asteroid belt naturally formed with enough mass distributed through the belt to justify the formation of a belt-wide atmosphere given the follo...
