I was wondering if planets die after a certain amount of time, perhaps because of decay? If this is the case, how do they die and how long does it take? Do they implode? Explode or perhaps just f...
Obviously the greater a planet's gravity, the stronger the material of the space elevator's cable would need to be in order to support its own weight. However, doesn't greater rotation speed reduce...
In my current setting, one of the main dominant species' is the Golem, former automatons made of assorted materials who gained sentience through some kind of life-giving explosion. As such, though ...
Given a world where a sentient species already populates, how would the population respond to another, unrelated species evolving into sentience? I think this can be effectively split into 3: It...
In many Science Fiction books and games, there are worlds or planet-like objects that are rings that orbit (or float around in space) (some examples being the Halo (from Halo) or the Ringworld (fro...
So imagine this scenario: Sapience (which I define as Human-like intelligence or better) is a relatively common occurence once a life-form is on a specific brain-arms-race path like Hominins have ...
When viewed from their planet, are moons always the same colour as ours? Or is there a variation? What other colours might be possible and what causes the differences in colour?
As part of my world's planetary history, an asteroid impact has delivered a sizable quantity of a previously unknown metal to the planet Earth. By sizable I mean a deposit large enough to sustain a...

In a civilisation similar to humans (although not necessarily humanoid) living on a planet the size of Earth, could the whole civilisation (no limits on size, although I was thinking a few thousand...
Imagine a very long bridge (Visbi Bridge - named after the designer) across an immense canyon - really almost a wide deep gorge -use on an earth-like world. My concept is that part of the support o...
In a relationship between two species, could a certain relationship become harmful to both involved species? Keep in mind, I am looking for a relationship between two species, preferably of the ki...
I'm wondering what types of firearms would be impacted if explosives and combustion in general were to have a random chance of being more potent or less potent. Could new firearms and/or ammunition...
What sort of circumstances would allow for a parasitic relationship between two dominant species of an Earth-like planet? The criteria for an answer is as follows: The relationship must involve n...
Imagine that humankind finally takes wing and reaches out into the heavens to claim its vast cosmic birthright ... ... only to find that a previous wave of dinosaurs from Earth, who left ~65 milli...
Suppose a planet is covered with floating ice on top of water ocean and has no dry land. Would it be possible to establish permanent settlements, cities? Particularly I am interested in technolog...
So I've been trying to create a world and I've been planning on the continents being drowned out almost completely in water from a terrible tsunami, storm, earthquake or an act of one the gods or s...
I've always loved well-done ghosts. However, I've always hated the afterlife-speculation that they engender if used in a story. So I need a way to get ghosts without the fluffy spiritualistic bits...
Could one construct a statue out of materials that could be made to move in controlled or semi-controlled ways? The question is essentially can one make a robot without the internal mechanics? I'm ...
This is the second question in my Arctic Airships series of questions. The first one is Arctic Airships, Part 1 - Generating Electricity. The setting is outlined in Part 1, but I'll rehash the pre...
I'm going for the ultimate in world building here: Creating a whole new star. I have a race that's about a Type II civilization (as per the Kardashev scale). The important thing here is that they'...
