Rewriting the question to clarify: The time and location is now in our current Earth. A wandering red dwarf flare star (like Wolf 359) is moving towards our Solar System. The question: How close co...
Is a moon made entirely of water possible? Could a planet made completely of water exist? I was inspired by the above questions to ask the following: Assume that our current Moon is replaced ins...
I'm no rocket scientist, but I've been reading up on some basic concepts of rocket science (including some great talks here). As far as I've gleaned, there's two extremes of rocket thrusts: high sp...
Working on a future history setting; the question arises, since the world cannot run on fossil fuels forever, one way or another, something must end up replacing them; what will that something be? ...
In the year 2071 the Dysnomia incident happened. The Dysnomia (a mining ship) suffered a catastrophic failure and violently exploded sending its payload, an aged comet, hurtling towards earth. The ...
The original idea was a race of matriarchal desert nomads, but most desert nomad societies I could find as inspiration were strongly patriarchal. I can change this aspect if I don't find a way to ...
On the planet Blob there is an unusual phenomenon. It is known to emanate from the planet's core but 2018-level scientists have no understanding of it. The phenomenon Gravity isn't constant. It v...
I'm looking for a scientific explanation as to why smaller pebbles and rain would slowly fall upwards without the planet itself orbiting far too close to fry every living thing on the surface. A wa...
I have an idea for a story where human live on world with low gravity and a dense atmosphere. These humans have developed artificial wings that are attached to their arms so they can fly. Since the...
I've done a fair bit of research to come up with this scenario. I hope it's not "too broad" to ask for a reality check. Have I overlooked anything? Does it all sound plausible? My world takes plac...
In Warlords, my own sci-fi project, I wanted to tap into exosuits, but didn't want them to be one off rich boy toys or just make little to no practical sense. So I'm wondering what industry, if any...
In the new setting I'm making, I found an opportunity to make a species of humanoids that I simply couldn't resist. So I got to work, making the tribal herdsmen and hunters of the predominantly car...
This one might be a bit weird, but here it goes... In designing the evolutionary history of my world, I've devised an evolutionary branch of animals adapting to terrestrial environments. Lacking r...
I'm trying to work on a chapter in my lore but I'm stumped on how agricultural developments could work in tropical settings, and real world examples so far mostly include temperate places, I.e. Bri...
We are in a world very similar to ours. But, one day, 1% of the children that are turning 10 are gaining super strength (this is an ongoing process : from that date, all the children under 10 may p...
Objective: Replace the human digestion apparatus (stomach, guts etc) From my basic understanding the human body needs food, because it needs ATP (energy unit, some kind of sugar(?)) or you could s...
My story takes place in an archipelagus in world X, inhabited by people X. In the shores of the capital city of that archipelagus, there is a bay of deep, dark waters. It's supposed to be dark and...
I knew that energy is a scalar quantity, so I wonder can a character move and alter direction of an object at distance by giving it kinetic energy? Thanks.
I'm not sure if it's even feasible, but I have a server farm in my book, of a size that puts it on par with Google's. I want to wipe out all the data stored on the hard drives, without destroying ...
I writing a story about a physics student who has a difficult relationship with his estranged father, world famous physicist and strong proponent of string theory. As a revenge he wants to rule str...
(Edited for clarification) The general popular conception of how aging works is that your body grows and develops, reaching completion at some point in your late twenties or early thirties, and th...
A side shot from my series on a computer-less future; see here, here, and here. Project Rho defines a torch-drive as an engine with both high acceleration and high exhaust velocity. A torch-ship i...

Let's say that humans were biologically immortal. Once they reach adulthood, they effectively stop aging. Due to disease though, the average lifespan is 100 years. (In practice, your access to heal...
