I'm putting together a scenario, where a "Sun" and some debris are flung so distant that 14 billion years after the big bang, it has an "Earth" (and maybe some other minor rocky/icy objects), but n...
I would like to make something interesting about a culture of mine in one of my story proposals. I was thinking something along the lines of using living tissue for construction. Hard hides would c...
I know in fiction Sonic The Hedgehog is able to run faster than the speed of sound but could an organism actually evolve to move faster than the speed of sound? What type of fuel would such an org...
I'm working on a planet wherein the dominant species isn't humanoid (in this case, mantids.) However, I'm unsure as to whether or not it'd make more logical sense for the dominant species to be co...
In this more realistic scenario than typical fantasy, the vampire is just an ordinary human being with a certain genetic quirk that results in the following: A reversed circadian rhythm (active a...
Some of the answers to this question got me thinking: Customer service, emergency services, and doctor's bedside manner can be programmed and tuned for the task rather than having whatever-we-got ...
Discounting the actually quite good idea of having the asteroids be the site of colonization would it be better to use human miners or automated ones? Both would probably deliver the goods by unma...
Definitions Hamada: A type of desert landscape consisting of high, largely barren, hard rocky plateaus, with very little sand because this has been removed by deflation. -- From Wikipedia ...
How long can a river be? Are there any physical limits on its length, coming from the necessary altitude drop, the triple point of water, or other factors? You can alter whatever parameters you f...
As you might know, most planets that have atmospheres are not the ideal temperature to live on. For example, Venus is a very, very, very hot planet with constant volcanic eruptions and especially t...
The brain is 1 major developmental difference between us and these humanoids. These humanoids start off with larger brains to begin with and so brain development in the womb happens at about the s...
At the height of the last ice age, glaciers as thick as one mile reached as far down south in Europe as London. This is the reason why England and Wales have very little mountains, and why the ter...
Lets say we have a huge cigar shaped habitat, filled with a breathable atmosphere, and rotating on one axis at the right speed to have about 1 'g' of acceleration on the inside surface. To give th...
Earth, far future: We built multi generation ship which can get 20 000 people to another solar system in next 20 generations (600 years) For scope of this question assume that ship itself is well ...
Could I, purely in quantity of material only, build a solid bridge to a star? Ignore anything like strength, relative motions of systems, that is all taken care of, using lalalaicanthearyouium - t...
Let's say we're composing a message intended for radio transmission to intelligent alien life. We'd like to talk about sizes and distances, so we'll need a unit of length. We're already planning ...
The Hippocampus is a mythological creature and has typically been depicted as having the upper body of a horse with the lower body of a fish. Considerations Gills or lungs? Would this creatu...
Medusa is a legendary myth about a woman with snakes for hair that turns anything she looks at into stone. How can I achieve both of those features in an animal realistically? And how would these f...
The Setup A while back, I read an article in which the author compared the rise and fall of civilizations in the universe to a forest. In the forest, small plants come into being, grow, and die o...
I've recently become interested in the possibility of silicon based life. Assume these creatures developed on a planet with zero carbon (don't question, just accept it), so they have no carbon in t...
We Earthlings like to live in gravity wells but also have a taste for the exotic and are a bit lazy. Why not make colonies that take advantage of local conditions? Cloud cities over Venus, much le...
I've been getting nowhere myself on this. My goal is to create a human or humanoid that absorbs heat to survive. As a result this can quickly freeze things solid. I need a way to make this, for lac...
So we have the animal that breathes ice and the traditional fire-breathing dragon. We even have animals on Earth that can emit electricity of over 800 volts. But what about another element, wind?...
When we think to interstellar communications, we immediately think to radio signals with medium or large antennas : We all know about radio signals in seti. In the case of fictional stories, s...
So we all know that Lemmings are known for following blindly to their death but that is not the reality. I would like to create the myth in the real world, or rather I would like to know how suc...
