I would like to have a space whale type creature that can fly through space. It would be very large and fly from planet to planet using orbital maneuvers. I want this creature to be able to do it n...
On the generation ship in one of my stories and possibly more, there exists a positive relationship between the egg laying humanoid aliens who have an egg pouch on their chest and the humans they a...
NASA received a telegram from the direction of Proxima Centauri stating that the abominable snowman are coming for a visit and they expect snow to fall everywhere even along the equator. They also ...
There is a alien species known as the Titanians. The Titanians are organic biologically, but of a alien biochemistry much more cryophilic and oily. They drink ethane, breathe oxygen (you can ha...
Here's an idea that I've been toying with. The aliens are real, they are here and they dominate at least a part of our galaxy. How did they overcome the vast distances and why haven't we noticed?...
A common problem I have with modern science fiction and fantasy (Halo, Mass Effect, Narnia etc) is that the aliens and animals are somehow able to speak in perfect human speech. How does an alien o...
Being inspired by the lovely concept art of Star Trek's Nibiru, I have long thought that the Nibirans would use the tiered pools for aquacultural purposes, and would like to implement tiered aquacu...
An alien race wants to test out its new technology that modifies the atmosphere of Earth and other terrestrial planets, they decide to center it over Central Park, NYC. One of the first things they...
Its the year 2050, and extraterrestrials have popped up next to the Solar System. We know they are coming our way and we know they are most likely hostile. As Steven hawking said: Such advance...
I can think of at least 2 movies that had aliens invading Earth for water. Is this a feasible motivation? I was thinking that Water is H20, i.e. dihydrogen monoxide The vast majority of the uni...
Some information about their homeworld: Their homeworld, 0.34247 (M⊕) 0.54 G, 10156 km. The atmospheric pressure of their homeworld is 62% of the Earth's, and the planet has an average temper...
I'm writing a story about an alien race that is blind and deaf: They communicate based on touch and scent, and have a tech level generally similar to us. I'm assuming that they can measure frequen...
The hybrids were created when unseen aliens sent SETI a message explaining how to combine human and alien DNA. (Ignoring the scientific illiteracy and contradictions in the films) Under the constra...
Would non-water based alien life have different life speed than us? (I have studied some chemistry in CPGE in 1978-80, but I was very bad at it) IIRC, chemical reactions are (exponentially) faste...
Let's say the dots on Ceres are abandoned alien outposts. Within the next 40-200 years humanity manages to send a team of research scientists to the location. The scientists quickly found a way ins...
Alternatively, could DNA be a language (the normal coding that exists within DNA to tell it what to build) that is capable of telling us anything. This question is based off of this article about...
Vertebrate tooth enamel is made from Hydroxylapatite, however this need not be the only material available that an alien species could use to make teeth or tooth-like structures. Given that an ide...
What would be the most effective feet design for sustaining massive weight and also allow for the ability to climb? The organism in question has 12 limbs, 8 of which are large and strong legs that...
Let's say you're an alien and you want to make sure your species outlives your planet or whatever disaster you currently face, whether it be natural or engineered. You load up a bunch of self-repli...
I'm trying to design a species that is largely aquatic and yet capable of walking / running (loosely) on land. I've already figured out a gill and lung type respiratory system to allow them to brea...
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 ...
I have a more or less primitive (They can not talk to other races nor was any encoding or morsing or smoke signals invented) alien race the MLPARs (10000 individuals), which was parted in half and ...
Like this question I'm wondering about design considerations for an intelligent aquatic species that wants to travel into space. Would they have to try and create special body suits to keep moistur...
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...
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...
The obvious hitch with a superdense atmosphere is that, even without being super deep as well, it absorbs light. Just as the bottom of the ocean is dark even just miles deep, an atmosphere as dense...
Would it be possible for a moon that receives a lot of tidal heating from its gas giant parent planet like Io to develop intelligent life? Assuming moon is big enough to support an atmosphere and i...
Let's say an alien species discovered Earth and wants to land here and establish contact, however their homeworld's gravity is only 46 percent of Earth's, Would it be possible for them to be able t...
Let's say I have been chosen to evaluate whether or not alien worlds contain sapient life before we terraform them. Just assume that we learned to work together and live as a species in peace, trea...
I have a captured planet/moon orbiting HD 37124 c, known as HD 37124 c m XVIII, and I was wondering: since the moon has 1.7 Earth masses, 1.1 Earth radii, a density of 7.038 g/cm^3 and a gravitatio...
One day, in modern time, the space agencies of the world detect a strange structure drifting through space. NASA manages to redirect the course of this structure, and with their new solid handwaviu...
Would scientists on the other side of blast survive in a bunker? I got an alien using telekinesis abilities to move Moon with the speed of " 1 hour till collide from the moment Moon left the orbit"...
In the book The Host by Stephenie Meyer, a parasitic species (Souls) attach to the back of the spinal cord of alien creatures to control their brains, but I find this a wee bit unbelievable. As it ...
In my story where thousands of humans are transported to the planet with dinosaurs that is 400 light years away, there are bound to be lots of warnings on the generation ship. Friendly aliens are t...
I was thinking of an organism that lives its entire life in outer space. It would be shaped like a rocket and have skin to pressurize its insides so that its internal organs are pressurized even w...
I am wondering if alien race detecting our signal could actually understand such broadcast. But for my story, I need the aliens being unable to understand what we are broadcasting. How can I achie...
Merfolk can be easily described as humans with the lower half of fish. On this site we have discussed; How their tails work, How they sleep, And how they hear. But there is one question that has no...
Aka: What I am asking is: what are the basic elements a society capable of space travel needs? What key factors determine a species'capacity to become spacefaring and what cultural and societal asp...
I have this idea of homicidal alien beings that upon death (after their body ceases living and begins to decompose) release enough poisonous gas into earth's atmosphere to wipe out all life on the ...
I came up with an alien species that has the following reproductive life: They hatch out of eggs, tended by their mothers, and by the end of the first year (about two Earth years long) they are ...
I know water would be out of the question, but what about liquid nitrogen or liquid hydrogen, Would silicon work instead of carbon?
I'm fond of a insect race in a videogame, and want to base a race off of them, or write a fan fiction, but they flex a bit in the torso, and I wasn't sure... Hope this makes sense. :) Animated pi...
I have an alien species that is my pet project. Now I'm to reproduction, which I have a specific idea for, I'm just not sure exactly how it works. My creatures are aquatic, and everything goes on u...
From the answers I received in my previous question explaining why a humanoid society couldn't live atop giant mushroom caps, I have considered going back to my previous idea of them building their...
Purely hypothetical and kind of creative quesiton. My idea is an alien humanoid-like civilization (and basically everything alive on that planet) which uses methanol/ethanol or other alcohol as a s...
If yes, what are some possible ways they could break through the ice and explore the surface?
Background Information Let's say that we are trying to catch the attention of other potentially intelligent species. This signal would be used to attract the attention of other intelligent species...
I am creating a hypothetical race of aliens native to a planet orbiting an F class star; the mass of the star is 1.50 (M☉). Would this star live long enough to allow the evolution of intelligent ...
Imagine that, without any aliens having been ever found, we get to a point where we can build sub-atomically precise simulations of reality, spanning at least something the size (if not the likenes...
Could there be life on or around Planet Nine (a real-world planet in our Solar System, which has recently been discovered through indirect methods)? Of course, it probably receives nearly no solar ...
