Could an unmanned solar plane go not only above the clouds, but also so fast that it always is in the day-side of the planet? A solar plane flying above the clouds receives sunlight $12$ hours per...
So, after going through a some rough calculations, I figured my earlier question ran into a few problems regarding the final velocity of the asteroid. I pulled the mathematics a bit incorrect, so I...
So, I ran into a problem regarding the aftermath of a colonial war for independence. What happens is the following: The scenario is this: late 24th Century, humans have colonised the Inner Solar Sy...
My idea was to use 2 stages for an interstellar spacecraft (particularly the Orion Drive) and use it in a way similar to Project: Daedalus. Phase 1 would involve accelerating to cruising speed foll...
I'm not into psychology, but I've heard a lot about veterans who have committed suicide, went crazy, became addicted or have their lives ruined in other ways because of the shock they lived through...
Nobody knows where the big Blue is. Some people say it's a dream. Some people say it's the space between the worlds, where all the things that fall through the cracks end up. The occasional rains o...
Sometimes I reminisce about the giant eagles from The Lord of the Rings and two things come to mind: Boy, I wish I could have my own giant eagle! Could a bird even carry something that heavy on i...
Epimetheus is a planet with about three times the mass of Earth orbiting a sun-like star in the Andromeda galaxy. However, two major factors separate Epimetheus from Earth. First, it has a thick at...
Okay, so the heat death of the universe is approaching. You can't stop it. You can't dodge it. What do you do? You wait it out. According to wikipedia, about $10^{{10}^{56}}$ years after the heat ...
Many authors describe worlds with higher gravity than our own, from whence super-muscular aliens originate. However, as we increased the size, mass and surface gravity of a world; there would be p...
It is estimated that in about five billion years, our sun will enter its red giant stage. During that phase it will expand and completely engulf Mercury, Venus and possible Earth. Earth will either...
To start with, i know You measure the Kardashev scale from stellar success, but lets say we have a civilization that are vastly advanced compared to us, so they are equivalent to a type 2 civilizat...
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 ...
