I'm looking to create a highly advanced insect communication network that could be broadcast on an interplanetary basis. Now, my insects communicate through chemical signals and smells which they...
Say we built two large scale portals and sent one to Venus and one to Mars much like in this question but with portals large enough that mass flow rates are not an issue seeing as nobody wants to w...
How could an earth sized and broadly / liberally earth-like planet have plate tectonics but still experience zero or weak / little earthquakes? How can I have the weakest earthquakes possible while...
From this graph it can be seen that Water Vapour can never be held by the Martian gravity, and would escape into space. How would future terraforming processes overcome this loss?
I am writing a story where the main setting is a hollowed out asteroid with an interior biosphere and an exterior city. In this case, using centripetal force to simulate gravity would not work, be...
There is an interstellar civilization somewhere between K2 and K3 and they have managed to build a dozen Nicoll-Dyson beams. These are megastructures which collect the entire power of a star, and p...
I would love to shape my planet in a way, that allows me to have an extremely cold, icy desert, next to an extremely hot, sanddesert. By "next to", I don't mean a few hundred miles apart, with gr...
I am working on a world where, instead of 24 hours, a day lasts 9 years. On this world the land far exceeds the oceans, to the point where the bodies of water are simply massive lakes (a la the Cas...
In my story, I'm trying to create a natural disaster of sorts that severely limits the amount of metal used in society. Are there any processes that would be biologically compatible that irreversi...
What would happen if the entire inner surface of a Dyson sphere (not necessarily a solid shell, maybe a very dense swarm) would be coated into a highly reflective material? Let's say it can reflec...
So say that there is this ridiculously dense object that fits on Earth. It has a bigger gravitational force than the Earth, and for some reason, doesn't break it. It also has a smaller force than t...
I have developed a fictional planet with the following atmospheric composition; 60.4% Nitrogen 27.6% Oxygen 9.8% Xenon 1.5% Water Vapor 0.64% Argon 0.06% Carbon Dioxide Is this breathable to hu...
One lab accidentally developed a species of bacteria which doesn't naturally die, but multiplies at usual rate. (And the scientists didn't notice in time, so the bacteria escaped). EDIT after Alex...
The Scenario: A group of scientists on a research space station are conducting tests on a Bose-Einstein condensate. They can't figure out why it is that every time they get their condensate to for...
If for a 'magic' Reason a second planetary mass of roughly equal proportions to earth appeared in the same orbit as earth. Is there any way that both masses could continue to orbit and remain in th...
I am making a world to be the setting of my future fantasy works, which is to say I really have no story planned but I want to have a world for it when I do and I want said world to be likely give ...
While the colonization of the Solar system is underway, a new sport emerges: Spatial Rowing. The rules are the following: Each spacecraft has one driver (the contestant) The loaded mass of each ...
You don't need to be traveling faster than the speed of light to encounter some pretty major problems. At just 30% the speed of light (90 Mm/s) a spaceship of mass 4 x 10^5 kg (about the mass of t...
Setting: In the future universe, with technologies based on real science that we know that theoretically can be implemented (though not feasible with today's technologies) and sub-light travel, a h...
I'm quite afflicted with a specific set of conditions I'm trying to figure out. I'm trying to find a way (if there is one) that someone could be unconscious for roughly twelve hours under some con...
This applies to all types of weapons, from simple knives to handguns to assault rifles to even military gear, such as night vision goggles. How far into the future do we have to go in order to see...
Assuming it just spins at the same rate, the other way. Axial tilt is the same, year length is the same. Perhaps winds and ocean currents? What would the effect be on geography? Would deserts or r...
Some time ago, I imagined a world with one peculiar disease. People affected by it suddenly "fall" towards the sky, never to be seen again. What could be the scientific cause of such a disease? So...
Within the next decade or two, Earth is attacked by an alien fleet. The various militaries have some forewarning and are able to destroy the attackers by launching most of their nuclear arsenal at ...
I've been considering the term 'redneck', which is described by Google's info engine as coming "from the back of the neck being sunburned from outdoor work." As I've grown more involved with the Re...
