What would a planet's rings look like from the surface of that planet? Would the rings be perceived to be stationary or move across the sky, and would the alignment of the rings relative to the ax...
There are plenty of threats out there that could terminate all life on our little planet in varying amounts of time (Solar flares, meteors and supernovas to name a few). Are there any disasters th...
I want to make a hot planet habitable for mankind. It could be a planet in the habitable zone like Venus or outside of the zone like Mercury. These are just examples. Someone said here:Â Terrafor...
I'm looking for a solution to generate a strong enough magnetic field for planets with iron-cores - in my case, Mars - to keep the atmosphere from getting blow away by the solar winds (and ignoring...
This question asks what would happen to the solar system if the sun vanished for about three days, the mass and energy of the sun simply ceasing to exist. This answer (as of this question, anyway) ...
When you look at the history of earth, the last ice age had major impacts on the flora and fauna of the world as well as biological migration. If I am creating an earth-like world and am developin...
I'm building an alien world for a game mod, and want to avoid any blatant mistakes from a world-building perspective. The world has three moons visible in the night sky - two on one side near each ...
Although a question about how large a living thing could be has been asked and answered, would a being such as Mogo from DC's Green Lantern series be possible? Mogo is the size of Earth roughly ...
I was looking at these two questions: Expanding Occupied Underground Habitations Safely Does Living without access to Sunlight have known Physical/Psychological effects? And in a story I'm writi...
Several science fiction books I have read (including, IINM, Nightfall by Asimov) have featured planets with several suns. Some worlds where this happened wrought interesting effects on the inhabita...
On a planet without axial tilt and with a roughly circular orbit, there would be no seasons. The climate on the planet would be, as far as I can tell, exactly the same at any time of year, and the...
(Disclaimer: I tried this question earlier in the scifi site as well as real science sites, and was told should be on topic here) I'm writing a speculative story about aliens coming to earth - and...
After reading the question on inbreeding (Could fictional species benefit from limited inbreeding?), I started to wonder if there could be any reasons why an species (intelligent or otherwise) woul...
Ragnarök is the Norse rendition of the apocalypse. A major event during this apocalypse is Fernir devouring the sun. If we assume that the sun and all of its influence disappear entirely for 3 day...
On earth most of our sealife is fishlike (excluding a few other species such as squid/octopus). As far as I'm aware there are no legged creatures which live solely in the sea. In my world I'd like...
I'd like to set a story in our solar system with Earth and the inner planets becoming uninhabitable and a new planet being required. If human beings decided to build a world by making slight deviat...
One thing that a few science fiction films seem to get wrong: it is extremely unlikely for two civilizations to evolve completely independently and yet be within a few hundred years of each other t...
Could a planet have an orbit in the shape of a figure 8 around twin (possibly binary) stars? Mostly curious about the physical possibility of such an orbital arrangement; is it stable over a long ...
What immediate effects would a small, short-term black hole have if it appeared in a residential backyard? How small or short-lived would it have to be to be survivable, if it is survivable at all?...
Suppose such an organism had evolved from using sound like most life we know to use different intensities, wave lengths, and hues of light to communicate. This is assuming that these creatures are...
Within the Star Wars Extended Universe, there is a science base on a small object within a near impenetrable sphere of Black Holes. Is this possible? The place referenced is called the Maw Install...
I was answering this 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 ...
Is it scientifically plausible for reincarnation to exist? When I think of reincarnation I am thinking of the following: Memories, personality, biases, opinions and feelings carry over from one ...
Following up on this question, Would Living Underground during Impact Winter be Ideal, I realized I have more questions. I was asking about an impact winter that was caused by an asteroid and lead...
I want to know about the plausibility and required parameters of the following scenario: Take an Earth-like planet, about the same size, composition and gravity. It has no plate tectonics to speak...
