As you say, just give them low-tech inertial dampeners. If you're using inertial dampeners to mean the same as I am, then we already have the technology to do this and it's used in many places. Ta...
When water is electrolysed with graphite electrodes some of the oxygen reacts immediately with the anode to produce carbon dioxide. Does a similar reaction ever occur at the cathode, producing meth...
The smallest warhead created for the US military was the W54 Davy Crocket which used 23kg of Pu239 and had a yield equivalent to 10-20 tons of TNT. Video of the Davy Crocket being fired. Accord...
Could nuclear energy be a basis for energy storage with foreseeable technology? One approach would be to use excited nuclear states, but I suspect they would be too unstable to ever be useful. Al...
Your planet could be really low on iron. There is a tree condition called chlorosis that is caused by low iron in the soil, and leads to light green/yellow leaves. It could also be that the PH i...
It seems like you could do it without even getting close to the speed of light if you could bend space. The whole "Imagine the universe is a 12 dimensional piece of paper. Fold it in half so that t...
Age: The time a star spends on the main sequence is roughly inversely proportional to the luminosity, as given by the formula $$T \approx \ 10^{10} \text{years} \cdot \left[ \frac{M}{M_{\bigodot}...
Orbit, rotation, mass and other properties not directly related to life A planet is a rotating mass (larger than ~500km in diameter) in orbit around the star of normal material becomes an oblate s...
Atmosphere, surface temperature and other properties directly related to life Magnetosphere: Magnetospheres are thought to be driven by a dynamo process driven by internal circulation in the ...
Special cases Tectonically-locked Mostly Frozen Surface Water-free (Dune) Or, no/very-little free water. All Water (Europa) Currently, by question definition, this is non-habitable. (Orig...
It could be a matter of resources. Missiles are expensive, flak is cheap, and has the added bonus of deflecting lasers. So if one ship can surprise another ship then a missile might take it out, bu...
Gawiser & Silk (2000) provide a nice overview of the CMB (possibly better than Wikipedia). The paper is a bit outdated - after all, they use a figure of 15 billion years as the age of the unive...
The fluff: I have a humanoid who's about to breach a door. He's got some upgrades to his body and can pump some stimulants through it to boost his strength, resiliance and speed to ridiculous prop...
Inspired by many questions that make use of utility fog. Utility fogs are not, as the name might suggest, fogs, but rather lattice solids. Cells of the foam are pollen-like micrometer-scale mach...
My question is: I need to improve the muscle fibers and nervous system of my genetically modified human so that it has dexterity and physical responses 4 to 10 times faster than the average human.Â...
A thought occurred to me, and I wondered if it could be made practical... This video talks about the possibility of electrical battery powered planes, and in short, while it may be practical to bu...
Normally, the human retina contains four types of light-sensitive receptors: three types of cones and one type of rods. The receptor proteins contain the chromo "” iodopsin in the sticks, the rhodo...
Respirocytes are an artificial analogue of red blood cells. Tiny sapphire capsules that can absorb oxygen in the lungs and release it in the capillaries. From the capillaries to the lungs, they, in...
My planet is tidally locked, airless, and has no magnetosphere. It's located close to a flare star (5% solar mass, 11 Gyr old), and is in it's habitable zone. The strongest flare ever detected on E...
My question is: What needs to be added or improved in the human body so that my genetically modified people can fully withstand temperatures of several degrees below zero ( "” 40 ° Celsius) for a ...
Right now I'm currently trying to calculate the average surface pressure at sea level of an atmosphere, but I'm having a struggle finding the relevant formulae with which to determine this number. ...
First time posting here but I would like to get some help with an issue I have. I have a planet that has 30% more gravity than earth. I have terrestrial animals with an exoskeleton, they stand at ...
I'd like to be able to determine the appearance of the night sky from an Earth-like planet, in a solar system with multiple other planets, moons, and other bodies. Here on Earth, we can directly me...
I have seen a variety of outer space megastructures across sci-fi and the minds of most astrologists, such as Bishop Rings, O'Neill Cylinders, Bernal Spheres, and much more. What most of these inte...
No, this is not not about courtship displays or dominance figths. (even thought I know that that is also part of mating) This is more of "What their genitalia would look like" and how they would "...
