This is the second part of a series of questions I'll ask about a self-sustaining colonization ship. I'll keep editing this post as things unfold. If you can, check out the other questions of this...
This might be more fit in physicsSE, but since I don't even know if my premise is physically sound, I'll post it here. One day, something caused the universe to get mirrored, meaning a left-righ...
I have a bacterial organism called the "World Blight" this creature's life cycle revolves around being introduced to a new planet, spreading across the planet and terraforming it to its liking, and...
I was recently redesigning some mostly hominid Aliens I designed a long time back in high school and felt were a little lackluster, and since they were already Tall, Wiry, and vaguely Shambolic-Loo...
I am writing a scenario for a game that I am a fan of. It involves an asteroid heading for impact with the Earth in 2027. This asteroid's initial diameter is about 1km, but it is slowly disintegrat...
I've just bought myself a shiny new spaceship equipped with the latest in FTL warp technology, the only catch is the fuel bill, this thing drinks the stuff like it's going out of fashion (still, it...
Lately I have been thinking about possible forms of life on planets that would have radically different experiences than here on Earth. I was wondering if life based on transition metals was possib...
Death occurs in extremely high humidity and an average temperature of 23 C (~75 F), both of which continue for six weeks. At that time, temperature begins to fall over the course of eight weeks to...
I'm trying to create a planet which environment is not immediately lethal to humans, (reasonable oxygen level) however after closer inspection turns out not to be specially Earth-like. One issues ...
I'm building the world of my story for my comics and I've come to a bit of a standstill with a particular idea. Assuming there were no other planets in our universe, just a single planet Earth. ...
Suppose I take a group of alligators select the ones that emit the highest frequency of radiation (since all living creatures emit thermal radiation), and I breed those, and get rid of the rest and...
I've got a species that lives in the Southern Ocean along the Antarctic coast, and they are basically a sentient crossbreed of Orca whales and elephant seals. They are omnivores, have opposeable th...
If all of the crew and passengers of an interstellar craft were in suspended animation except prior to Earth departure and just before destination arrival, would they need artificial gravity (throu...
(First post on StackExchange, hello world!) The project that I'm currently working on involves a Binary Planet system, both with life, although I'm only focusing on one. This planet has a climate ...
So, I made the slight mistake of worldbuilding by starting off with just a planet's local sentient species and working from there. This species, the Trillek, have a more or less theropod appearanc...
So one of the ideas I've come up with for system to system travel, in the early colony stage of my world, is using fuel boosters to start the journey and then to reach the required speed for the co...
Much of the struggle with terrestrial fusion power seems to be with keeping the ultra-hot plasma contained. In a classic Tokamak configuration, magnets using massive amounts of power, suspend the p...
This is not a duplicate of Building Noah's Ark or Can We Build Noah's ark?, because the former asks only about a relatively small number of species and the latter is set in Biblical times. Ignori...
Consider a planet which is entirely Earth-like. Same mass, same rotation, etc. But in this world, resource-rich objects are suspended by some phenomenon at varying altitudes up to 200km above sea l...
Hypothetical: Hundreds of years into the future. Humanity needs to travel to exoplanets quickly. I'm aiming for hard sci-fi. What kind of propulsion can travel people at 0.1 - 0.9 lightspeed? Is i...
I have a terrestrial planet that is similar to Mars in many ways, a desert-like surface, thin atmosphere, and inhospitable to large flora and fauna as we know it. This planet has ceased tectonic ...
I've seen many questions about tides and tidal variations on a wide variety of interesting single star, multi star, single planet, binary planet, single moon, multiple moon, and even ring system co...
I can understand Super-beings' great strength and some of their other powers, but flying is hard to justify. I want to consider only superheroes that can actually fly rather than merely jump tall ...
In various TV series and movies villains or organisations have been shown to control animals through technological or cybernetic means, such as the future predators in Primeval. These creatures hav...
Basically, a sun-synchronous orbit is where one side of an object is always facing a star as it revolves around it (much like our Moon is, which is where the phrase 'dark side of the moon' originat...
