So I'm working on a fictional planet which would experience a daytime sky similar to this. This particular picture is from the movie Valerian: City of a Thousand Planets. Fictional alien atmosph...
I am looking for as hard science answers as possible, but I am willing to bend some rules for a good answer. Assume they need to move 10 million 100 million people off of a planet what technology...
Set in the not-so-distant future, interplanetary travels are the norm. Most spaceships are powered by fission reactors, and accidents do happen due to negligence or flaws in the system. It will pro...
I apologize if I continuously ask different questions about different concepts for stories. It's just that I can never make up my mind on what to write, and sometimes, my ideas change. But anyway...
My character is traveling aboard a spaceship through inter-galactic space (it has left the Milky Way). The ship is traveling at the speed of light or so and has been for the last six thousand years...
Say you see a fellow human walking on the street, nothing special, nothing new, but suddenly, BLAM, they're dead. You reasonably run away from the scene out of fear, but when you look back, the bod...
Let us assume at some time in the near future, medical science perfects a biologically safe liquid air solution. It can fill up the lungs of the adult human subject and they can breathe it potentia...
This is a submission for the Anatomically Correct Series Gargoyles are a staple of Gothic architecture and I've decided to give these creatures the time of day. Gargoyles are closely related to Ny...
I have an idea for a faster-than-light spacecraft that I would like to run by the expert minds in this community for a plausibility check. Basically the interstellar ship itself is of unspecified d...
We've just started 36th century, humanity is colonizing stars right and left. Technology is well developed, you know, typical Sci-Fi stuff. In 23rd century we finally were able to create true AI. ...
A long time ago a group of proto-giants moved high up into a the Sodo-Himalayas. Yetis commonly live up on high mountain plains some of basic characteristics of Yetis are: are as intelligent as ...
Inspired partially by this comment on one of my answers, I got to thinking on what the quickest way to communicate would be on an intergalactic scale. Say humans have colonised the galaxy, and use...
Strange! this question does not seem to be on site with a search (only what to wear). I am concerned about the psychological aspect of food production and eating. Clearly tube food is out and I thi...
Anyone who has studied ice ages would know that during the last two-and-a-half million years of Earth's history, there have been periods where there was enough ice to suck up a lot of water. As a ...
As a thought project, I wanted to make an alien species that eats without any use of the tongue, but I've run into the problem that it's almost impossible to swallow solids without choking without ...
Do you think it will become possible to create opposite sex clones in the future? A male clone from a woman or a female clone from a man? I think it will become possible. To create a female clone ...
So, aqua regia is a somewhat safe material for a living being to work with, but the problem is that it isn't metal enough. Somebody suggested in an answer to another question, that dragons would f...
A super-reactor was created by SRE, Inc (Super Reactor Energy), and it can provide as much clean energy as needed. There's no way to copy it or make another. It operates without problem or fuel - t...
Humanity has spread out in the cosmos, colonizing various worlds, cataloging countless creatures, the usual interstellar species activities. One day, however, humanity finds a species that is argua...
Of the living great apes, humans are most closely related to the chimpanzees and bonobos. We retain quite a few features from that side of the simian family, and it got me thinking about what a hu...
Say you somehow invented 50 thousand nanobots that are the size of medium sized bottle caps. Each are capable of hovering for a limited amount of time but do recharge with both solar energy and plu...
Contrary to popular belief, Unicorns are not related to horses but instead are descended from the Siberian Unicorn. Over time: their fur became whiter they became slightly smaller they have an...
