One of the solutions I think is making the muscle go inside the bone, something look like an exoskeleton creature. either mechanical or organic making the artificial muscle developed inside the mar...
The industrial company Astor since 2124 has equipped all "Long Hauls" (voyages beyond 3 months) with cryopofs in accordance with a new company bylaw and cost cutting measure (less resources the cre...
In JJBA: Stardust Crusaders, there was a two-parter with a falcon stand-user, called Pet Shop, as the antagonist. The character kinda intrigued me, so I decided to steal it while Araki wasn't watch...
In my world, humans encounter an alien species. They want to communicate verbally with each other, so I'd like to know what sounds could be shared by both species. The species has no/very thin li...
One day, you suddenly get superpowers! Whoo-hoo, you can speed up or slow down the flow of time for yourself. This means you can run faster than a jet, right? So you decide to test it out. You ...
I am building a sci-fi universe where humans have colonized the moons of Jupiter. They are very small and thus have low gravity. In fact, some of them have gravity equal to less than 5% of Earth. ...
My dragon So to give a quick description, this is a 2 mile long, nuclear powered dragon of doom. I think I'll going with a fission/fusion hybrid creature for this beast. Another piece of relevant ...
My world is at the outer edge of the habitable zone. There is enough heat and geological activity to start life, but a snowball earth is looming and threatens to freeze it all. There is some spring...
My world has a continent in the northern hemisphere that lies primarily in the Ferrel cell where the westerly winds are. The continent is fairly large, just a tad bit smaller then than North Americ...
We, humans, hold a lot of livestock. 19 billion in chickens alone. Cattle, sheep and pigs each also number over 1 billion. Currently these animals cannot evolve freely; they are selected on certain...
Warning picture showing dissected Russian Doll My theory I believe that Russian Dolls reproduce asexually. They are born pregnant. At the time of birth, the outer doll dies. What is now th...
The Romans had pumps, aqueducts, water wheels (which were used to grind flour, saw wood & stone etc), valves & pipes (they are known to have used stone, clay, lead & copper for pipes). ...
As we all know, a majority of the Martian soil is composed of ferric oxide ($Fe_2O_3$), which is also coincidentally the formula for hematite, one of the most common ores of iron. I think (persona...
I'm writing a story about a race that has space travel capabilities without rocket technology, instead is using a portal to space and was wondering whether it's possible for them to put something i...
Idea I'm interested in exploring the following concept: people have discovered a certain kind of matter, let's call it "Unobtanium" (as it always goes). Unobtanium actually has mass and is compri...
For a SF story I'm wondering how thick a planet's rings can be? When viewed from the inside, can the ring material be so dense that visibility would only be a couple of meters? What would it take t...
On my fantasy planet, humanoid peoples are at war and ride different animals into battle, including wolves. People and their wolves are, for all intents and purposes, extremely similar to humans an...
2 informational references for Alcubierre fields can be found at the end of this question. Warp-lanes aren't a novelty in science-fiction. Space ships can use a specific route to go through a Gala...
I made a question regarding floating cities coming from a misunderstanding of this great answer. Luckily one comment showed me how floating cities could be possible in a slightly different scenari...
Building on this question "Discovery of life on Mars" Mars is habitable (40% the mass of Earth, 6.06 m/s² gravity, escape velocity of 7.88 km/s, a satellite big enough to stabilize its axis an...
In my part of this (Earth-like) world, there is a stable community of completely isolated pre-industrial humans, numbering perhaps 1,800. They live at an altitude of (at least) 25,000 feet (7620 m...
So, we know that big creatures will generate lots of heat if they're active. We also know that wings are very good at venting excess heat. Now for most animals, this heat isn't exactly spectacular,...
Living in polar climates can be quite difficult, and staying warm can often be such an issue. But not anymore with the heat sponge! This nifty little organ draws heat from even the coldest water to...
Following my last question asked regarding oviparous humanoids, is there a way for evolution to 'regard' females as the more dominant gender without going down that road, forming a heavily matriarc...
