[Question] [ In my story, some aliens try to conquer humans by slowly copying their mind into humans heads. This copy process is called “enlightenment” by the ones who undergo the transformation. For example, by using [subliminal stimuli](https://en.wikipedia.org/wiki/Subliminal_stimuli) based technology like 25th fr...
[Question] [ An ASI (Artificial Super Intelligence) has [come to the conclusion that we humans should be put in a simulation](https://worldbuilding.stackexchange.com/questions/13696/what-directive-would-cause-an-asi-to-put-everyone-in-a-benevolent-matrix). It has also decided that it would rather not turn the Earth i...
[Question] [ Within my setting, there are many wild and unexplored lands, some of which are very dangerous, some of which are very benign, but few know how dangerous or safe a place is from the outside. So, there is a very well established Empire, that encompasses all of civilized humanity, with the power of administ...
[Question] [ Imagine we build a space station much larger than the ISS with more or less today's technology. (For example in a scenario in which price of transport to orbit per kg is significantly reduced by technological progress.) The design of the station might look approximately like the [Space Station V](http://...
[Question] [ I was answering [this](https://worldbuilding.stackexchange.com/questions/2655/living-planet-possible/) question about how a living planet-organism could be possible, and realized I didn't know how such a planet-organism could produce a magnetic field. I postulated that it could somehow use revolving magn...
[Question] [ A staple of time travel stories is a moment where the meaning of “before” or “past” can't be taken in the simple normal way, and everyone laughs at the novelty. In reality, a trained ChronoCop Agent would have the vocabulary to succinctly refer to the situation. Now an extended set of tenses is overkill ...
[Question] [ Chlorophyll as we know it on earth is estimated to be between [3% and 6% efficient](https://en.wikipedia.org/wiki/Photosynthetic_efficiency) in converting light energy to useable biomass. This support slow growth and no movement of plants like that observed in herbivores or carnivores. Higher up the food...
[Question] [ While we develop space travel technologies, the Moon will always be the first destination. By its proximity to Earth is the obvious target to test our technology. Before we can establish some kind of mining base in Mars, for example, we probably will do that in the Moon first. Isn't altering the Moon mas...
[Question] [ [Some species](http://animals.pawnation.com/examples-marine-animals-external-fertilization-9753.html) that [reproduce sexually](http://en.wikipedia.org/wiki/Sexual_reproduction), don't actually *have sex* as such. Instead the female might lay soft scaled eggs, which the male then [fertilizes extrenally](...
[Question] [ First off, let's get definitions out of the way: A "race" here is defined as stable, heritable, phenotypic, clearly visual distinction between large demographic groups living in different geographic areas - but all of whom actually belong to the same biological species (e.g. can freely and effortlessly i...
[Question] [ Let's say that I, like many other worldbuilders before me, want to have 'classical' (space-operatic) space fighters and carriers in a space setting. However, I *don't want to do it by fiat and handwaves*. Instead, I would like to make such a military doctrine (of having classic space fighters) to **emer...

[Question] [ Alien and fantasy creatures can be designed in an infinite number of ways. But are there physiological traits that would be common among all tool-developing (technology-building) species? As an example, I suspect all such species must have some means of manipulating small things. Whether it be fingers an...
[Question] [ I'm working on a planet that has very similar conditions to earth. Now, I had the idea of animals having four (or even more) lungs. Would that be possible (I imagine there must be a possibility to inhale large masses of air to sustain all lungs?) and if yes, what would the benefits and other effects be? ...
[Question] [ OK, here's the problem: I want to have a spaceship that is built for transporting large machines (in particular, heavy mining equipment). It does not and is not designed to leave space; transport down to a planet (if necessary) is done by other, specialized ships. It is operated by two people, and its fl...
[Question] [ Imagine if Earth's atmosphere was shrouded in a perpetual layer of clouds or haze. Enough sunlight gets through to make agriculture still possible, but people are completely unable to see the stars. Thus, the science of astronomy can't develop until the invention of aircraft capable of rising above the c...
[Question] [ Ok, I know the rather annoying mathematics of animals that rely on photosynthesis. But another question got me thinking about this and I had a thought: what if my planimal gets only *some* of its energy from photosynthesis? **Juvenile phase:** The juvenile planimal is a very small organism that can swim ...
[Question] [ For the sake of analogy, let's take the Chixclub impactor and move it a mountain range akin to the modern Himalayas. Obviously we're dealing with an extinction level event here so I'm not concerned with the effects on life, and only loosely interested in the atmospheric effects. My primary concern is wit...
[Question] [ I would like to include a world in a story that is located on the upper plane (or bottom, doesn't matter, but call it upper for the sake of reference) of the galaxy. If you think of the galaxy as a cookie, the world is on top near the rim, not in the middle of the cookie. I could imagine that inhabitants...
[Question] [ **Is it possible to calculate/estimate the size of a star's heliosphere? If so, how?** I am working on a semi-near future, sci-fi novel. As part of the technology base, humans are able to travel between stars near-instantly, however they must first get to a warp-gate of sorts outside the heliopause (oute...
[Question] [ How to design a realistically looking technocracy? I mean that’s a standard problem in even mildly SF setting.

[Question] [ In [this question](https://worldbuilding.stackexchange.com/q/8978/75), I proposed a system of democracy for a city state that is being encouraged away from autocratic rule, however the system I proposed appeared to have many faults. As a bit of background, this is a city state with an area of influence a...
[Question] [ Is it possible (for humans)? My main concern was heavy gravity because they are much bigger and heavier. But it appears that in our system, the gas giants (but not Jupiter) all have a similar [surface gravity](http://en.wikipedia.org/wiki/Surface_gravity) as Earth. Actually I'm not sure if by surface the...
[Question] [ Normally we watch the sun descend, it's dimmed a bit by the atmosphere before dropping below the horizon. What I'm interested in is how big it would have to be so the atmospheric dimming is sufficient that the point it dips below the horizon is unnoticeable. --- **External Edit:** This is how I understan...
[Question] [ I'm working on a tidally locked world. I would like to have some life in the dark side of the world. The sun heats all the air on one side of the planet and winds high in the atmosphere transport it to the dark side of the planet where the air cools, drops and reverses flow back to the hot side. That mea...
[Question] [ In a class discussion last week, someone pointed out that a typical core collapse supernova releases $\sim10^{46}\text{ J}$ of energy in the form of (anti-)neutrinos while only radiating $\sim10^{44}\text{ J}$ in the form of photons. This then means that the energy flux from neutrinos is about two orders...
[Question] [ Many species of amphibians, fish, arthropods and even certain reptiles go through metamorphosis. But, to my knowledge, there are no mammals that go through metamorphosis. Let's say I want there to be a mammal species that goes through a metamorphosis. During this metamorphosis they would start and finis...
[Question] [ There are theories of ancient cultures which might have been visited by aliens. Most of them have been proven wrong but the I like the idea and want to set up such a culture which has been visited. **Background:** There are many ancient buildings of civilizations which suggests a knowledge about stars th...
[Question] [ Assuming a civilization has the technology and capability to build a worldship, a planet that doubles as a spacecraft, installs an FTL drive on it and has the energy to power it, what would the effects be, on the object and it's inhabitants, of traveling at speeds faster than light? There are two cases t...
[Question] [ If you want to have a smaller star but you also want to keep your planet in the habitable zone, you need to put the planet closer to the star. This means shorter years. It is also possible to have a larger star and a longer year. Specifications: The planet is not tidal locked to the star. To have any...

[Question] [ I am trying to come up with an explanation for how a creature could create strong magnetic fields with a high level of control. I'm thinking that their 'writing' would be similar to how computers write to hard disks, which is why I'd like them to have a fine degree of control over this ability. I do have...
[Question] [ I've got a home-brewed D&D setting. Diamonds, in D&D, are needed for resurrection magic, so access to diamonds is literally life and death for any country with clerics capable of casting such spells. The outcomes of wars will likely hinge on which side can control access to diamonds better. So, where do ...
[Question] [ Okay, let's assume that travel between star systems is done through stable, stationary wormholes on the outer boundaries of each system.

[Question] [ My first post here, and it's more about destroying worlds than making them. Consider this scenario: An earthlike planet where a powerful magic spell has been cast, protecting *all positrons* from annihilation on contact with regular matter. Stable antimatter can finally exist (in a sense). And positroniu...
[Question] [ I did a little looking and it appears stars outside of 10 parsec/33 ly will have very little effect on the Earth. What it did say was that inside that range the gamma rays would affect our [ozone layer](http://en.wikipedia.org/wiki/Near-Earth_supernova) which would reduce our radiation protection. How cl...
