How would a planet need to be changed (gravity, air pressure, air makeup, etc) to allow for the realistic flight and take off from a small hill of a gryphon with a human rider? You can assume the ...
I want to partially terraform Venus, enough to make it feasible to mine minerals etc,. there. To do this I need to do a few things but for this question I'm focusing on stripping away at least some...
4+ light years away, aliens living on Proxima Centauri B have space travel and incredible technology, but are not interested in traveling out of their system or in returning our radio-babble, rathe...
OK, so I'm writing a Star-Wars-esque science fiction book set some centuries in the future. Rather than break the laws of physics and say that faster-than-light travel is possible, I've chosen to g...
Hope this isn't too broad. I tried to make it as easy to understand as possible. A list of these technologies would be great
This is one of a series of questions centered around living on a giant tree. The setting/scenario is described below: In my fantasy world, elves live on a giant tree, very similar in structure...
As some of you have pointed out, the only universal problem of stun guns is their "dosage", as some people may survive getting hit by a lightning bolt... seven times, others get themselves killed b...
I was told that building a tunnel into the centre of Enceladus is not possible, since it has subsurface ocean and molten, rocky core. But its brother, Mimas is a bit smaller, and shows no sign of ...
I am building a science fiction universe, and I am currently thinking of many different unique sentient alien species that would populate the galaxy. I have thought of a rocky planet with Earth le...
Rana sylvatica, the only amphibian found north of the arctic circle, has a very unique survival strategy: it pumps its body full of glucose and hormones just before freezing so that ice crystals do...
I'm my previous question I asked about the longevity of caves, now I'd like to figure out the longevity of the cave dwellers. Specifically, I'd like to put some bounds on how long they can hibernat...
So I writing a story where we terraform Titan using super heavy green house gases where the lower part of the atmosphere near the surface stays warmer. Because of this, a portion of the moon's icy ...
I'm creating a universe where ftl space travel is possible by folding space. You can only travel point to point with direct line of sight. The example I plan to give in the book, to clarify, is th...
The extreme pressure and temperature greatly reduces our ability to drill holes deeper than some kilometers into Earth's mantle. However, on a body smaller, colder and less dense, this would be a ...
In this Answer I suggested that an animal could have a tampani acting as a loudspeaker, as in Vernor Vinge's The Blabber, later featured as the race called Tines in A Fire Upon the Deep. In the ori...
I'm thinking of adding humanoid squid into my world, as an expy of the bloodsuckers from the S.T.A.L.K.E.R. games. These cephaloids somehow fell into our universe from a parallel one (they don't kn...
I just want to make sure my science and animal biology is correct here. If there's an increase in gravity to 2-3G, would livestock develop to be more lean due to muscle development or would they ma...
Crude Oil, is a term used to describe petroleum products harvested from geological formations beneath the Earth's surface. As a fuel they maybe called hydrocarbons, hydrocarbons can be found/creat...
In 1815 Mount Tambora erupted throwing so much dust into the atmosphere that the year became known as "the year without a summer". *There were a few other mitigating factors but Tambora is thought ...
I love chocolate. Today, when I was making myself a cup of hot chocolate, I was thinking about Easter and about all the chocolate I am going to eat. And at some point I was wondering: How awesome...
Someone made the Earth. They placed man on the surface and gave them plants, animals, the waters, and the mountains to make their life compete. The Earth exists within a spherical firmament upon ...
All our mammalian friends are replaced by domesticated giant insects! Man's best friend are now dog-sized hissing cockroaches, fireflies are lighting our houses and harvestmen are used for transpor...
This plant I am designing grows on earth, in locations where competition between plants is fierce, water is scarce and also nutrients in the soil are diluted. The dilution requires the plant roots ...
For example, a street this wide to have enough blood run down the length shown in this photo? Assume that the blood isn't going down storm-drains for whatever reason and assume the stretch of road ...
I define "generalization" as the ability to put things together into groups based on common characteristics. I define "abstraction" to be the ability to articulate what those characteristics actua...
