Using my world changing invention and my massive intellect I have created the perfect defensive tool for myself and any minions valued friends I deem might need one. The tool is a super suit that ...
I'm designing a world, and I want it to have major geological changes over a short period of time. This includes continental drift, which I'm assuming should have some interesting results. In parti...
Our universe is described as having three physical dimensions, plus one time dimension, where the eigenvalues for the physical dimensions are all the same, but the eigenvalue for time is opposite (...
I'm currently writing a story, but however I'm having trouble with one part. The hero is faced with a situation where he has to create a fire strong enough melt 5 kg of copper, and he only has a ma...
Nuclear rockets, or as I like to think of them, "half way between a continuous small atomic explosion and reactor whose front fell off". There are many variants, and my aliens are using relative si...
I've read that even in a "perfect" vacuum, matter exists in the form of virtual particles that spontaneously pop into existence only to be immediately annihilated. This suggests to me that it might...
I know the default will be blue, but just HOW blue, i.e., wavelength in nanometers? I have a world with the following stats: Radius: 4628 km. Mass: .35 Earth (2,09076 x 10^24 kg). Atmospheric D...
I've been reading here for a little while, but this is my first question. I am trying to come up with either a concrete set of numbers for a single answer for a binary planet system, or a simple fo...
A star system consisting of two stars forms, with one being more massive. As such, the larger star soon exhausts its fuel and ends up as a neutron star. The secondary star has a semi-major axis of ...
There is a predator that lives in the forest. It is roughly the size of a large bear, and moves quite slowly - a person could outrun it at a light jog. Nor is it agile - although its arms and jaw...
If the holograms are really advanced like the hologram of Snoke in The Force Awakens and they are haptic, which means you can feel them, can they be used to make an immersive virtual reality envior...
I am creating a creature which uses infrasound to immobilize prey and I have done a little bit of research on the effects of Infrasound on animals, finding that 177 dB with a frequency between 0.5 ...
In Larry Niven's short story "Bordered in Black", there's a planet (Sirius B-IV) with much lower gravity than Earth. As a result, the planet has a gentler atmospheric pressure gradient, i.e., the a...
I'm working on a species of large bird, and trying to determine whether they will be able to fly or not. I know that this equation likely applies: $$ A = \cfrac{L}{\cfrac{1}{2} v^2 \rho C_L} $$ ...
So I'm writing a story (set well into the future and on a different, but similar to Earth planet colonised by humans) and as part of it I am including specs and designs for the armour that the mili...
Project Orion was a project to construct a spacecraft that rode the shockwaves of nuclear blasts as a form of propulsion, but the project was abandoned because of budget cuts, environmental concern...
My worldbuilding involves a reasonably near-future, high-realism space station research outpost, and I'd like it to be powered by a nuclear reactor. However, I need as much detail on the actual rea...
Is there any way for a planet to host, even a tiny amount, of matter in a superfluid form, without outside intervention, given that Helium-4 becomes a superfluid below 2.17K, and that according to ...
If a parasitic creature was discovered, how would officials determine whether that parasite was a new species or an existing parasitic species? How long would that process take? Assume the specie...
So I'm thinking about orbital warehousing of raw materials but I'm wondering whether one would actually need an orbital structure to store the goods inside or could you just strap a booster to the ...
So lots of Sci-fi works use mono-crystalline diamond as a wonder material used to build all sorts of impressive and in some cases seemingly impossible structures, I'd like to ask about the science ...
The exposition is that a civilization exists about 200 light years from earth and has been capable of radio communication for several thousands of years. They are not trying to hide from detection ...
Assuming the ship has access to fusion power, a large volume of solar panels, and crude antimatter power generators (say maybe 1 gram a day per generator, or whatever is reasonable for technologica...
How much wattage would you need to accelerate a four petaton spaceship by 1g for a year? This should be about enough to reach near light speed, which is perfect for interstellar cruising, but I'm w...
Considering the rather hostile radiation environment on Europa, what communication and navigation systems might be used with near-future manned spacecraft? What would the ranges and features of th...
