Setting: Western world nation, Earth as we know it, May 2016, Gregorian calendar. Eccentric billionaire, large multinational corporation or similar; lots of money, and ability to enlist the help of...
The dwarves in my world are humans who starting digging caves in the Maumturks and Twelve Bens in Ireland during the Iron Age, and eventually connected the caves via tunnels rather than trudge acro...
While I do know that there is no possible explanation for how we might wake someone up from such a long sleep, I was wondering what food would be edible after one million or so years where the huma...
Satyrs, fauns, pan, and even the devil are commonly depicted as humanoid bipeds with goatlike unguligrade hooves for feet. However, common as such beings may be in fantasy and mythology, I have bee...
In my story where thousands of humans are transported to the planet with dinosaurs that is 400 light years away, there are bound to be lots of warnings on the generation ship. Friendly aliens are t...
Is there a way to either counteract the effect of gravity on a planetary scale or create a planet with a low enough density so as to replicate the effect of weightlessness? My world takes place o...
What scientifically would make it possible that certain large bodies of water be impassable while others that seem very similar are able to be navigated? This is not what I am attempting to do, bu...
If we want to be realistic, we imagine ships pushing stuff out the back and relying on the conservation of momentum to move forward. Gravitational waves carry momentum. Are they viable as a kind o...
One of the settings I've been working on is a retro-futuristic world with a technology level and aesthetic of the early cold war era, something quite similar to the setting of the Alien franchise i...
Enter the [Insert cool and awesome Latin name here] - this species is 3 times the size of a lobster from front to tail, and a powerful hunter. Operating in swarms, they are my worlds equivalent of ...
Is it possible for a earth-like planet to orbit a neutron star & have intelligent life-forms, even if said neutron star 'moves' through different galaxies? as seen in this video - https://www....
I recently read this article (http://www.space.com/5985-hottest-planet-discovered.html) about a hot Jupiter that orbits it's star about once a (earth) day. This and remembering how high of an albed...
In my universe, spaceships use a device that can generate a bubble of gravity that is homogeneous and unidirectional. You can manipulate the direction and intensity of gravity in any way you want. ...
A scientist has recently invented a gravity machine. This machine pulls all mass within a certain radius (say 50 feet?) towards it at an adjustable rate. The machine can... create as strong a g...
In the latest Artifexian video, he talked about terrestrial moons, bringing up great ways they could and would exist. But the video ended with an interesting concept, Horseshoe Habitable Moons. F...
Ideally this would be some sort of sun or star-related natural disaster that would affect the entire planet and make life outside of protected/shielded areas extremely dangerous. This is a human-in...
Is it safe to assume that any two binary planets of 0.5 to 1.5 Earth masses having mass ratios of 1:1 up to 2:1 would always have become tidally locked to one another long before any life could nat...
As anyone who has watched the Jurassic Park series knows, Hollywood likes to exaggerate a bit when it comes to dinosaurs and their scientific accuracy. Many facts are fairly easy to prove right or ...
Could a creature reasonably have both armor (in the sense of armadillos or pangolins) and be able to change color over the short term (less than a day)? I'm afraid I don't know enough about biolog...
This creature is a waterdweller that somewhat resemble a fish. It lives in the retreating oceans of a planet orbiting a star that is reaching its red giant stage. The planet is now experiencing ver...
Let's presume there's a world much like ours in the not so distant future, but as time goes by storms become stronger and more frequent. That as far as I understand this is already something relat...
I recently finished reading the novel "Seveneves" by Neil Stevenson. The central premises of the novel is that an unknown object has caused the moon to break into several large pieces, with an imme...
In a question about mermaids, it was proposed that they might have evolved to look like humans to lure them in and prey on them. How could a creature survive on a diet of nothing but lured-in huma...
Let's say that after decades of development there are now cities on Mars. Most of their facilities are located underground in order to protect them from radiation and small meteorites, as well as p...
So what size comet/meteor/rogue planet could wreak havoc on a populated world without killing off intelligent life entirely or actually ruining the planet for life? Assume the world being affected ...
