In a setting I am presently working on, I have envisioned a world similar to Star Wars' Takodana, in that its water is mainly in the form of large rivers, or smaller seas (I generally picture it b...
Let's pretend the clouds got there via magic or some bizarre scientific experiment gone wrong. The why isn't important for the question. Question: How would the earth be affected if its entire sky...
____________Useless Backstory_________________________________________________ In my world, A hurricane has washed a group of 8,000 pachyderms off of Afro-Eurasia and onto a large island cl...
Is it possible that a monkey-like creature, in the mountains, could evolve to have no legs and a really strong set of fore-arms? I was thinking that this might be possible because of the climbing s...
The habitat of the creature in question is most commonly atop mountains (or in moist areas). Such an idea would mean that the creature wouldn't need a heart or stomach to break down things into blo...
Please assume the following: A spaceship in the far future. Output: The ships systems have a high base demand of energy and sometimes you need extreme amounts of Energy in a very short period of ...
This is a follow-up to question about a transmuting 3D-printer Assume you need to store all stable elements in a spaceship. On board, a chemical assembler is used to compose everything, if you hav...
Far Future. Almost every household has a 'fabber'. You put raw materials in it (can be almost anything) and it does what you program it to do. It transmutes the raw materials into what is needed. T...
Assume there is a point in time when every planet in our Solar System consists of colonies. Each colony is inhabited with civilians that primarily serve the purpose of its colony. Some colonies m...
If half the earth was made antimatter and contacted the other half all at once, would the resulting energy be enough to "destroy" the observable universe? I did some math based on the mass of the ...
In my world, there are a race of microscopic humanoid organisms (0.3 mm - 0.33 mm). They live in a variety of biomes, such as leaf litter, stone and on plants and trees. In terms of technological a...
In my pre-bronze age city, there are roughly 20,000 individuals. 9,000 sexually mature males, 9,000 sexually mature females, and 2,000 children. For a variety of unimportant reasons, they have been...
As a variation to my previous question about the domestication of microbes So my question is : which animals lend themselves to domestication?
Essential Question : what adaptations can be made to a crawling vine that would allow them to obtain as much energy as a top level consumer if the vine was on a planet 1 au from a sun sized star?
On a world like Venus, where the surface is unlivable , would it be possible for life to evolve in caves? And if so , is there any reason for intelligence to evolve in a subterranean organism?
The consensus (1, 2) is that the reason most continents have relatively few large animals compared to Africa is that humans, even stone age humans, were able to drive them to extinction. African a...
In my world, I am attempting to design a primitive organism to be the ancestor of life on an artificial planet with all chemicals necessary for life. I want the organism to be as small as possible ...
If a matrioshka brain where constructed specifically for AI , and , say , 1,000,000 AI were placed within it , also with many hostile enemies and various obstacles which may cause the destruction o...
I was wondering if a full aquatic bird could exist and not be on, or return to land at any developmental stage, basically, to be completely independent of land. I already know that there are some a...
In one of my fictitious planets, there are large cells that reside in the ocean and are 3 feet (almost 1 metre) in diameter. The cells themselves are aggregates of many amoeboid cells, have only on...
I am in the process of creating my universe, and have based it on semi-hard science. The universe that I have created is quite extensive, and I thought that it would be unreasonable for the only ki...
In the year 2020 A.D. , the inhabitants of earth are visited by a not-so-friendly race of techno-pathic AI aliens ,numbering about 500,000, and originating from a type 2 ¾ civilization from a gala...
For a highly intelligent avian dinosaur whose grasping and manipulating appendages have all but vanished, there are options : for the species to evolve beaks that are better fine manipulators, or c...
On my fictitious planet, a 1/2 pound mammal had a brain to body mass ratio similar to that of a human , could they have human - level intelligence, or would the brain be too small the develop that ...
Continuing from this question: The rodents on the synthetic planet ( which I am now calling Ark ) can now walk/run erect when desired. The scientists continue with biological forging and work on t...
