If we assume their homeworld is similar to Titan, but instead orbiting a Neptune sized gas giant and a bit bigger and receiving the same amount of Solar energy as Titan, The star is a main sequence...
I'm writing a science fiction novel set 100 million years in the future, but humanity is still the same basic form we have today, biologically speaking. Would 100 million years of evolution drastic...
In this alternate scenario, there is a clear ecological distinction between broad-leaved deciduous trees and coniferous trees based solely on altitude. The broad-leaves and other angiosperms are t...
Within software environments there is a variety of malware such as viruses, trojans, bots and so forth. This malware is created by human programmers to accomplish specific purposes (e.g. steal pers...
In an old story of mine, there happened to be a species of humanoid who could produce a variety of mutants and hybrids from stolen and harvested DNA, sperm, and biological tissues. They would produ...
Let's assume this planet has had a normal lifecycle up to this point, becoming an Earth-like world with around the same climates, size, landmass, day/night cycle, and has a single moon of similar s...
So I've got a bunch of freeze-dried colonists traveling in torpor to a solar system 55 light years away at 92% c. From an outsider's perspective it takes them sixty years to get there, but how long...
Consider an Earth like planet is orbiting around a Sun like star, it is almost identical to our Solar system, except the orbital inclination of the planet is 90 degree to the equator of the star (n...
Is it possible that a large, multicellular, naturally evolved organism with an advanced intellect on the order of a human's could have evolved to pass on its knowledge and memories in a fashion tha...
For my story I am working on, a peaceful alien race that is studying Earth wants to terraform the Moon by building a giant sealed dome over its entire surface, then they will create forests, desert...
In my latest draft, a worm-like species buries itself deep below the crust of their world and consumes/gathers tiny amounts of heavy metals. Can you think of any plausible reason why a wormlike cr...
In this alternate scenario, five million years ago, a mass extinction hit Earth. Not a massive volcanic eruption or a devastating bolide impact, but a sudden cold snap, a transition from Miocene h...
One Czech sci-fi author presented idea on his feed on how people might deal with contacts in not so far future: Imagine you can have your own "personal assistant AI" loaded to your smart phone. I...
Imagine an alien race. They are the creators of Unspecified Advanced Alien Technology™. One day they lose one of their ships. The crew had to evacuate, and the ship kind of crashed on a random plan...
These moons orbit a Jovian planet with 0.52 Jovian mass and at 1.02 AU from a star with 0.98 Sol mass. 3.85 Days, 0.351 Earth, 0.68 G 15.4 Days, 0.242 Earth, 0.59 G 30.8 Days, 0.118 Earth, 0.44 ...
I'm trying to work out some really basic biochemical details for cold-world aliens whose bodily fluids are based on liquid methane rather than water. I figure they have to be hydrogen breathers, be...
So a scientist in the somewhat distant future is living on the final pages of the chapter that we call 'humanity.' For various reasons it's impossible to sustain human life (outside the scope of th...
There's a species called Foos. Foos are fairly similar to humans. In a primitive society, in fact, they would appear identical to humans in actual physical appearance, mannerisms, and base behavior...
As a follow-up to this question: Could an asteroid aerocapture around Earth? The answers seem to indicate that it would be possible for such a thing to happen (an asteroid aerocapturing using the ...
Due to an unforeseen malfunction your intergalactic spaceship suddenly drops out of hyperspace and comes to a near full stop. The ship is damaged, and will need to be evacuated soon...very soon. Y...
The story situation is that a generation ship is headed to another solar system where there are several planets in the star's habitable zone and once the ship arrives, it will approach these planet...
So this question is about a humanoid species I was thinking of: They are semi-immortal and live long life spans, which poses the problem of not having enough space for new memories after a long t...
The idea of a collective consciousness (Or Anthill) is pretty simple: instead of cells you have small sentient animal that make up a larger creature. This is different from a hive mind in that the ...
The primary purpose of the human nose is to detect scents. This is an obvious statement, as is that the primary function of the mouth is to eat. The secondary purpose of both of these features is t...
Let's say that a secret laboratory creates a simulated miniature universe- in which modifications to people, places, and their 'state'(say age, gender, powers, DNA composition, among other things t...
