[Question] [ I'm in a D&D campaign where astronomy plays a big deal. I want to name drop and reference some good astrology myths about evil or cursed stars, but I'm having an awful time finding anything. The only one I have for a reference to start searching is Algol, the demon star, which I found from an old Lovecra...
[Question] [ If I were to have a generally earth like world, with water and land masses very similar, what could you add to make storms happen more often, and more specifically, lighting storms. I know lightning happens because of friction in the clouds between dust particles, but could increase the amount of lightni...
[Question] [ (Please see diagrams) This is a question regarding an area of a Rocheworld scenario that I haven't found anything on. It is suggested that the OUT side of a planet that is tidally locked with another is actually exposed to the vacuum of space because the gravity has pulled the atmosphere away from that a...
[Question] [ I understand that asteroids are very very far apart, but everything I am reading about asteroid mining omits any information about what happens to the waste rock or "tailings" that would presumably be left over. Is it loose rubble or ground powder? Does it not become an operational hazard, at least to th...
[Question] [ Let's say a setting contained a world like ours. Due to unfortunate circumstances, a large portal to hell opened up in the middle of the planet. Numerous demons spilled out into our reality, overthrowing governments and killing billions of people. These demon hordes were led by devil archons, who settled...
[Question] [ And not some big space gun a mile wide, I'm talking more like "could you pack a nanogram of antihydrogen into a shotgun shell or rifle casing and fire a bullet with it?" A few conditions and assumptions: * The gun is made from futuristic polymers, alloys, metamaterials or whatever that would allow the b...
[Question] [ Most of the planets that we know of have a sidereal day (rotational period) that is shorter or on the same order of magnitude as their sidereal year (orbital period), the latter being the case in tidal locked bodies.

[Question] [ One of my characters has the ability to manipulate time, and thus I've found that if used properly, that ability isn't presented with much in the way of obstacles. Once time has stopped, unless they are facing someone with the same abilities or some physical challenge that would be difficult regardless, ...
[Question] [ I’m writing a post-apocalyptic novel, but I have a problem when dealing with daily life in a post-apocalyptic war zone.

[Question] [ I'm writing a graphic novel on the premise of a world that has a liquid or semi-liquid atmosphere, separate from a true liquid sea. But since I don't want 'Magical Underwater Adventure!' I've decided (tentatively) on a 'gaseous semi-liquid with non-newtonian-fluid-like physics' - i.e. under low pressure,...
[Question] [ I was watching the movie The Martian and I realised afterwards that thanks to its really great CGI, some people think it is based on real story and there are even some who think it was made on Mars.

[Question] [ Would a salt flat be near a river? I have a world with a Nile River-like region and within a few miles, perhaps 10-20, I have a massive salt flat. The arable land of the river brushes up against eastern edge of the salt flat but all the other "borders" are surrounded by a Sahara-like desert. Is this real...
[Question] [ In my world there was a sentient being who was able to witness the evolution of life on the planet for a few million years. He watched as human beings evolved from monkeys.

We have Gas Giants that contain a solid core but are mostly atmosphere. We also have the possibility of a liquid planet as discussed here: 3. [Could a pl...
[Question] [ What could drive a human civilization to use base-12 system? As far as I know there have been such civilizations and they probably used their phalanges to count (instead of their fingers).

[Question] [ Terraforming would not strictly be the appropriate term for the type of planetary modifications I am asking about. Say humanity develops advanced AI robots, who are then left alone in space (as humans have completely perished and Earth destroyed). The robots may have a vague memory of what Earth was like...
[Question] [ Here I'm thinking about something loosely similar to what Clarissa Mao has in The Expanse, in which she is able to have limited superstrength and agility for a short period before she passes out.

[Question] [ My fairies are hunted for food by basically anything that’ll eat bugs, mice, and small birds. Humans also target them because wild fairies are seen as a nuisance (and a tasty nuisance at that). How can they fight off all of these creatures?

[Question] [ Cold and Flu, are common viruses which normally infect us in the cold of winter. Ironically, those people who always keep themselves warm, stay less out-of-the-house and office, keep their windows shut, and don't venture out beyond essential travel seem the most affected. I usually prevent those infectio...
[Question] [ We Eldar are a beautiful race that have a maximum life span of 500 years. We are stronger, faster, more intelligent, sexier, and frankly just superior to you humans in every way.

[Question] [ In this answer <https://worldbuilding.stackexchange.com/a/25219/50641> (to the attached question) one of their counter points was "oh, crows use tools, therefore, human advantage negated". That got me thinking, could crows build a spaceship? Obviously not with their current level of intelligence, so I pr...
[Question] [ **The Society** The society in question is feudal in structure. The most advanced widespread technology defining this society is the flintlock muzzle-loading firearm (I'm undecided as to rifled or not, but leaning towards not).

[Question] [ This planet is fictional, but I want it to be credible all the same. It is the same size and composition of Earth, orbiting a sun-like star. But that's where the similarities end. The planet's orbit is far more elliptical, coming just into the 'too hot' section for a few days twice on its closest approa...

[Question] [ So an area has a bunch of dragons. These dragons are intelligent, but instinctively solitary (that is, the way they feel about living in a group is analogous the way a human would feel about living alone) and therefore do not have a very integrated society.
