Writing a story in which a human is trapped on an alien planet with an average temp of 6 Celsius, and I want to have the atmosphere be too rich in oxygen, but not to the point where an air tank is ...
Suppose that humanity has spread across the universe, colonizing various habitable worlds, until their empire spans the entire galaxy (or near enough) - but there is no sign of alien life. There ar...
In order for different humanoid races (humans, elves, orcs, dwarves..) to evolve, they need to be separated for a long time, in different environments. However, if all races are supposed to be sent...
My team of researchers has created an AI to increase human suffering and the machine has started earning money on the market. The ministry of economics has sent a technician to review the machine a...
So my planet is tidally locked, it constantly faces its star like the moon faces Earth. One side is completely frozen, the other is burning hot. There is an atmosphere that allows life, and people ...
In a world I am building, a race of humans exists on a tropical archipelago with a very hot climate. Their skin, naturally, is very dark, but I want to have their eyes [most, if not all of their e...
Let's say it's sometime in the future, and humanity has expanded outwards into the solar system, and we've genetically engineered some really big plants that can for some unimportant reason, surviv...
First the reality-check: In a sci-fi world where humans have interstellar travel but "nice" Earth-like planets are rare, what reasons might an algae farm be "better" than a plant farm, especially ...
The Intergalactic Colonization Authority has a problem. They've recently discovered this awesome planet they want to colonize, but it's located in a part of the universe most of the rest of the civ...
In the real world, humans have tamed horses and use them as mounts. Horses have very specific characteristics that make them a viable mount, such as size, back-strength, stamina, diet, behavior, et...
On my fictional planet humanoid aliens have evolved on one continent, and have since spread around the entire planet, just like humans did on Earth. On Earth humans have since developed slightly di...
Yes, I know that this is quite a BORING question (get it ;) ), but I really DIG this kinda stuff (no really). If you have watch an action children's show or a cartoon of some kind, we have all see...
Imagine an Earth-like planet with a moon that is closer to the planet than ours with a lunar cycle of 18-19 days. I am trying to imagine how this different cycle would affect human beings and anima...
A fault that ruptures causing an earthquake can cause a chain reaction of dynamically triggered earthquakes in nearby faults, thus causing a much larger seismic event. What are some high unlikely b...
Right, you are standing on Earth 100 million years in the future and observing the sky. What would you see during night and how would a day look like when you look up. Weather is not relevant (no c...
Alien AI DoomFleet has a mission: Destroy threats to their creator. They do this by detecting the signature of FTL drives, going to the system, and blowing everything up, up to and including the ho...
Because water ice is less dense as a liquid than a solid (as an aside - this is due to the basic structure of the oxygen atom) it floats when frozen. Without this property ice would sink, basica...
I'm attempting to write a story, in which the main character needs to be in stasis for a couple hundred years. Upon researching the idea of cyro-stasis I have found that there is really no way to p...
Which body in the Solar System is the best candidate for being an artificial construct, placed there by a Kardashev Type II Civilization? Some notes: The purpose of this body is to monitor eart...
So I put JDlugosz's answer, the MJOLNIR Mark VI and the utility fog into a blender to get 100% pure AT-Field (copy). How does this work? Small nanites make up the shields intercepting part. T...
How long would it take for the earth's crust to move in such a way that we, as a species, will be forced to migrate to other different lands than the ones we inhabit today? The result being that ou...
I am trying to figure out the climate on my planet. If there is an asteroid ring around the equator will it cool down the equator? And if it does cool down will the planet still be habitable? My ...
Can I use nanotechnology to make the strongest possible non-nuclear explosive (when compared to the equal amounts of other explosives) or are we already at the peak-level of what can be achieved wi...
What could cause the majority of a rocky Earth-like planet to have to have persistent extreme weather at least for part of the year? By extreme weather I mean cyclones, lightning storms, tornadoe...
Ok I'm not exactly sure how to tag this or where to ask, but... Could someone create living, breeding-viable wolf adults with the genes responsible for Siamese points (as found in the cat breed), a...
