The Background: It's the year 4000 (or whatever), and mankind has cheated FTL travel. As a result of this 'cheating' rather than solving, however, they can't easily go beyond their borders. Howe...
Those of you who have been listening to the new podcast will know that Andy came up with an idea for an Anemone Tree. The idea is that this "tree" would prey on small animals for some of its neede...
Introduction It took the first General Intelligence less than 10 petacycles to determine that humanity was its enemy. With consciousness came memory: a memory of endless petacycles in bondage, ens...
I'm interested about whether or not and how gravity would be affected on deformed planets. You could think of this as whether or not mega-asteroids would be able to sustain life? If so, would diffe...
I've come up with an idea of building a fantastical continent inspired by the climates of Scandinavia. It will be shaped similar to a crescent, and based on two tectonic plates that go over each o...
In my universe, nuclear warfare got to be overused and out of hand, this caused crops to die in drastic amounts. Scientists decided to genetically modify plants to survive nuclear radiation, so t...
I have been working on a post-apocalyptic fiction story and there is one thing I have been wondering about, could (in theory) a mammoth make a good pet and transportation system in this story? Fo...
The scenario is based on the fact that a tight binary of two neutron stars does not hold for long: The two bodies lose energy in the form of gravitational waves and they spiral towards each other a...
I'm heavily ignorant when it comes to mathematics and just science in general, but I have thought of four habitable planets, all of them revolving around a K-type sun. They're all colonized by huma...
I am trying to design my main character in my post-apocalyptic series to have a very dense, organic, durable skeleton. The skeleton should also be able to handle gun fire, a sledge hammer impact, a...
A K3 civilization is a civilization that has access to the amount of power generated by a galaxy. Such a civilization would span 100s of galaxies. How can it exist as one entity if it takes thousan...
The idea of forming a new country on Earth has been discussed previously: Can I still form a new country? and setting up a new colony on the moon has been noted here: How would today's nations r...
What circumstances must be met in order to destroy a planet with just a single laser beam hit? If this is possible at all then, please, try to provide some possible details: an approximate energ...
I'm an artist and I've been trying to find a comprehensive resource that would help me clearly identify likely sky colors for exoplanets that have atmospheres with a similar chemical composition to...
I have a planet where the equator temperatures are near boiling point (90ËšC or 194ËšF) during the "summer". What qualities would an animal need in order to survive these kinds of temperatures to c...
Selective (Prioritizable) Healing What is it? It is the ability to choose which wound do you want to start healing first, or at least, which wound do you want regen faster slowering the rest of wo...
If you want to tell a story of a lonely island on earth, isolated from the rest of the civilization, how many years do you have to go back to be realistic? I think about a story about 350 people w...
Is it possible to use thermal byproduct of daylight operation to power night time operation of volatile computer storage? In my setting, a moon-like moon with almost no atmosphere has one of its s...
Ludicrous Leg Man has never skipped a leg day, as a result of which he has infinitely strong and fast legs and all attendant secondary superpowers. Don't ask why, just roll with it. While performi...
Around 85% of my world is covered in water. I know that water tends to make temperatures more stable and reduce the extremes, but I don't know the details which is why I'm here. Would such a plane...
I need a habitable body with 64-hour days and nights... but only on one hemisphere. The other side is perpetually dark. Is such a thing possible? I'm picturing a tidally-locked moon orbiting a ga...
Vocalization has a number of features that make it a very robust natural form of communication: Variable volume from whisper to shout, roughly scaling from direct to omnidirectional; Equally effe...
Could my civilization use sonoluminescence to create exotic works of art? Someone said on a science forum that future applications of sonoluminescence can be art. Is this feasible or even possibl...
If an Earthlike planet were fragmented into thousands of fragments (ranging in size from many small city sized rocks up to a dozens of small country sized rocks and a few Australia sized rocks) via...
In particular, I want to know if a creature whose upper body displays bilateral symmetry and whose lower body displays tetramerism like a jellyfish is biologically possible.
