Let's assume that the earth has stopped spinning. To be clear, the earth did not end up being tidal locked with the sun, but instead, it would just stop rotating around its own axis. This should re...
I have a sailing ship. It leaves port. As it goes away, it grows smaller and smaller. In our world, it eventually is hidden by the curvature of the Earth, such that the top mast stays visible longe...
I'm trying to devise a planet where the atmosphere can sustainably combust in certain conditions. However, this planet must be able to support human life when the atmosphere is not undergoing a com...
In the Halo series there's a habitable planet called Harvest with a diameter of 4,012 kilometres, and gravity 99% of Earth's, though the planet only has 9% of Earth's mass. If such a planet is poss...
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...
If there was to be a habitable planet, similar to earth, but with varying gravity at different points on its surface - lets pretend that it varies from .8g to 1.2g - what sort of terrain or form wo...
Essentially, two stars of identical mass but different temperatures are in a binary system. One planet is directly in their barycenter, tidally locked to one and therefore both stars. The effect I'...
I need a meteor to deliver an extraterrestrial algae-like cellular life form to an urban environment/city. The meteor needs to be far enough that it will not impact the Earth and will not cause ...
A concept in ethics (specifically, Kantian ethics) is that a perfectly rational being, without dependencies, will not act immorally, because immorality itself is an irrational concept, only effecte...
I've been mulling over the idea of nanites (microscopic machines that perform work - usually to transform one material into another). I've come to the conclusion that at a macroscopic level, nanit...
I have a character who loses her forearm. To up the cool factor (and because this once happened in a dream of mine), I'd like for her to dip her stump in gold. Would this actually result in gold ...
Could these moons be tidally locked between them or would they get locked to Earth? What consequences would the orbital cycle of these two moons have on Earth's surface?
I'd like to send my protagonist permanently into the near-ish future. I suspect that something as simple as the common cold could be deadly to my protagonist once we get a little further along. I...
I am making a universe and I thought that it would be unrealistic for all life forms in my entire universe to be based upon carbon. I am aware of silicon as a possible replacement, but I'm looking...
Current Settings Humanity could no longer access earth for some reason (it could be anything from alien invasion, third world war, ecological disaster, etc) starting at 2028, and they know about t...
Something I'm working on- originally I intended for this particular species to build cities up in the treetops of massive forests, but that's been done before. So I considered maybe they built thei...
Another question on this site deals with the question of interstellar trade without faster than light travel. I'd like inspiration for a related but more generic question. Why would people choose t...
As we know, solar power is the ultimate source of energy for mankind, and it's the most abundant(I have read that we receive more than 1000 times the energy we currently use, if we were to have a w...
Inspired by Frank Herbert's Dune: Action Joe is kept prisoner in Doctor Evil's prison. Doctor Evil knows that Joe's escape is inevitable. So he decides to introduce poison to Joe's body. Joe gets ...
Many different books and novels contain creatures that have human upper body. But have the legs and thorax of spider. They are usually called by different names but they're sort of like centaurs b...
Tantalus is a character from Greek mythology who did some bad things (trying to feed his son to the gods), and in turn was punished in Tartarus: Tantalus (Ancient Greek: Τάνταλος, Tánt...
The host star for this hypothetical system is 1.05 (M☉) The gas giant is 20 percent more massive than Jupiter and orbits at 1.40 AU, now I need to know if these three orbits are stable around th...
As a variation to my previous question about the domestication of microbes So my question is : which animals lend themselves to domestication?
I am constructing a two dimensional world, but ran into a problem with one of the fundamental forces, gravity. I first tried to see what would happen if I just used the normal law of gravity, $\fr...
I need an event man-made or not on Earth that can generate consistent earthquake that never grow weak, sky is the limit meaning any astronomical events will be ruled out. My story can take place du...
