Consider the sharingan, a power in the anime Naruto that strengthens with the hatred you have (yes, the Uchihas are like ninja Sith Lords XD). The sharingan is 'awakened' after the person experienc...
Disregarding the fact that we can't create a 'star' on earth, what would happen when a mini star is created on earth with some hocus pocus, technology humanity developed 4 billion years later and E...
I am writing a science fiction short story, which is loosely about terraforming. The drama takes place on a terraforming site, which has been halted, in its early phases, due to the discovery that ...
Suppose there was a giant star at the centre of a system. It had managed to catch several smaller stars in its orbit which had in turn also trapped planets and their moons in their orbits. Would th...
I'm trying to plan a rotating wheel space station for a project. It should be noted that I have to stay as close to real physics as possible, although it takes place in far future. The space statio...
Long ago, I asked for a kind of steel alloy under an alternative recipe. Right now, the list is as follows: Carbon (2%) (Reasonable material and amount) Chromium (12%) (Reasonable material a...
After reevaluating my sense of perspective on sublight interstellar travel, I'm thinking of moving my planet closer to Earth to cut down on travel time and fuel costs. However, the planet my coloni...
What if there was an alternate earth where there was no landmass between North America and South America. For clarification, in place of Central America there would be a sunken land bridge at the d...
Suppose all the humans in Britain suddenly disappeared. This gives the animals -- wild, domesticated and feral, free roam. What would the wildlife look like 300 years later? The starting conditions...
How would an organism evolve to ''see''or sense things with high precision way before light hits its eyes or sound reaches their ears, or at least giving the illusion of doing so?
Imagine you had a flat earth scenario, in which the world is essentially a giant disc floating in space (I know that in reality any such world would be pulled into a sphere by gravity, but for the ...
Like on a scale of one to ten, how plausible are Alcubierre drives in terms of our current understanding of physics? Plausible enough to be considered "hard sci-fi", or are they just another form o...
Recently, I've been struggling to create an avian race that evolved hands to replace its wings. The consensus on that question was that it was not evolutionarily realistic for the bones of a wing t...
I was wondering if a planet that has a higher escape velocity but lower surface gravity lose its atmosphere more faster/slower than a planet that has a higher surface gravity but lower escape veloc...
I am trying my hand at a matriarchal society (human beings, technology similar to Earth's 13th - 16th century), and I find that for that to work they will need reasonably efficient contraceptives (...
Probably the most well-known exoskeleton suit is Iron Man. In concept, you'll usually see Exoskeleton suits with either tight-fitting joints (perhaps similar to plate armor, I'm not sure), or, y...
I have created a world map for a story I'm making. And it has been too long since I studied geography and geology. Assuming earth-like conditions, and a normal distribution of climate based on (a...
As the question asks, what would happen to the Earth if its core collapsed? Now I don't know if this is something that is possible or even realistic, but I found the question interesting nonetheles...
I'm making five habitable planets the size of earth as moons for a gas giant the size of Jupiter. Then I want to add many more smaller moons, Our Jupiter has 67 moons, I want as many small moons...
I'm developing a semi-realistic game involving stereotypical dwarves digging into mountainsides and carving out grand caverns for themselves, similar to those in Moria or the Lonely Mountain from T...
This sounds really stupid, but I'm trying to think of a way to make World Turtle work. And what I got after 5 minutes of careful deliberation, would be that the our earth would have to be 'flat' on...
Imagine you are an evil humanoid alien that wants to destroy Earth (or something awfully similar) for whatever reason. However as an alien, you do not possess any physical weapons. No laser guns. N...
So I'm working on building a city in my world and I've run into an issue with scale/size. I have the general idea of how large the city will be (~8 km diameter) and I am having trouble coming up wi...
Humanity is an advanced civilization, and has long, long since took to the stars. Their resources are seeming boundless, and their technology is fantastic. For some reason beyond our 21st century u...
Let's assume that sometime in the far future, ice-mining on Europa has become a very profitable business venture due to dwindling fresh water on Earth and the growing demand for more water from the...
