Assume there's a human being who can keep a strong electric potential near to (or on) his skin. Is it possible to use the air-ionizing property, or similar ones solely or mostly solely based on thi...
In A World Out of Time, per Schlock Mercenary, Earth is moved to a new home by lighting a fusion candle. The fusion candle idea is discussed in the Schlock quote: Building a gas-giant colony s...
Cloud Nine is the name given by Buckminster Fuller to his proposed tensegrity sphere airborne habitats. The principle is simple and the physics seem to be sound. For a sphere, as its radius is ...
I have two earth clones, in essence, separated by 16550 miles (26350 kilometers). They are, of course, tidally locked, and orbit each other once every 24 hours. These planets orbit a sun identical ...
Useless Backstory "Why are you waking me up Sergeant? And why did we enter near-light speed?" "We received a distress call, and there wasn't enough time to notify you, sir." "What kind of distress...
Before we begin, this system is created by aliens, and all orbits are on the same plane. These orbits are similar to earth's in shape. So, none of this has to occur naturally it just has to be stab...
How dark would it be living in an impact winter? Where would an asteroid have to hit earth to cause an impact winter? gives a great breakdown of the effects of an impact winter, but I'd like to k...
My basic question is could life 'as we know it' (carbon DNA/RNA based, using water as the main solvent in metabolic processes) evolve on a planet where the temperature ranges from 16 degrees Celsiu...
Recently LIGO discovered gravitational waves caused by two black holes that were orbiting each other, and then collapsed into one black hole. A few months later, we find out that this actually happ...
In my fictional world I have selected all parameters to maximize the Hills Sphere of my planet. The planet has three times Earth's mass and it is located in 2 AU from its star that's 1.4 times more...
Could one (and how much) generate electricity by building a wall connecting: South Africa to Antarctica South America to Antarctica Northern Canada to Northern Greenland Northern Greenland to Rus...
I have been looking at various animals that have evolved some level of aerial capability, and I came across Kuehneosauridae. Reptiles which evolved gliding struts, attached down their sides, which ...
Following on from this question: Can Cloud Nine be built? Let us assume we have constructed a Cloud Nine tensegrity sphere with a 2 kilometer diameter out of a durable material for use in Earth's ...
Earth, present time or very near future. Astronomers have just announced that it is believed that almost 9 billion habitable Earth-like planets exist in the Milky Way alone (this is true, but there...
Positive mass moves in the same direction as its momentum and if negative energy exists then it would move in the opposite direction from its momentum. I was thinking of a type of mass, known as "...
Basically, in the event of a blotting out of the sun á la an impact winter, what sort of food source (if any) could be used to sustain humanity? In my universe, underground/makeshift greenhouses ...
Consider a civilization with the industrial age technologies. Oil and coal are rare (probably used up). All products produced by oil and coal are also nonexistent. The civilization has invented ele...
For those unfamiliar, An impact winter is a hypothesized period of prolonged cold weather due to the impact of a large asteroid or comet on the Earth's surface. (Wikipedia) In my world I want...
Preamble The Alternity Cosmos II is a complement to a dice role-playing game that uses heuristics based on hard-science to 'build' plausible star systems for the Alternity game: http://www.altern...
Like it says on the tin. Problem? Basic configuration is not going to work. If I used several additional layers and all the Outer and Inner layers using carbon nanotubes, whereas the Middle Layer(s...
In this world a secret society "farms" people with desired features (personality appearances etc.). They have ectogenesis of course; but they can't afford personnel to take care of the "products" u...
Would that even be possible? Will the bones deform during early infancy? Will the cartilages between joints wear off faster? Will internal organs collapse under their own weight? I have no professi...
Well, gentlemen. Here is Part II. We know what to do about the manoeuvre, but we need to know possible tactical options the two Task Groups would use. Background Now, as previously specified, we...
When I was observing the Moon yesterday, I asked myself: What would happen if a meteoroid impacted the Moon on the more clear part of the Moon which we can see, leaving a crater of the size like t...
