Would it be possible to somehow inject astronauts cells with safe amounts of magnetic metals, or use some sort of magnetic properties, to hold them down to a space station floor with magnets?
In my high fantasy medieval world, the ocean is populated by underwater fish people and land dominated by your good old human. Different type of fish people (shark, whale, turtle, shellfish, etc.) ...
Here's the background. I'd like the planetary year to be just under 800 days, with a longer number of hours per day-cycle. If the settlers live in the Mediterranean type climate area only and use g...
Not a duplicate of "Overcoming language barrier; no speech" which confines answers to nothing that is clearly a form of communication; it focuses on translation, not physiology or evolution Not a ...
Some estimates put the percent of Earth's surface covered by landfills at 0.02%. Even if the world composted and recycled as much as possible, we would be left with an insanely large amount of w...
I have a metallic alloy called "Attrahite" in my world that conducts gravity the way that copper conducts electricity. Currently in the world, passing an electric charge through Attrahite "activate...
I'm building a Dyson sphere - a real one, like Freeman Dyson originally proposed, made of swarms of solar collectors in independent orbits that fully surround the star, something like this: Each...
If there's a habitable planet that orbits two suns like the above orbital route, what would possibly occur on that planet? Would it have two yearly seasonal cycle (compare to earth)? Would it be...
I'm considering a story set about fifty years (2065) in the future. It takes a rather optimistic view; space exploration has led to colonies on the Moon and Mars, as well as several space stations ...
UPDATE!!!! - FINISHED THE SCULPT :D [UPDATE: Much Much bigger response and feedback than i anticipated, I am hugely greatful and overwhelmed by the ideas and the help, I will keep the thread goi...
The most common explanation of what would happen to a space-ship that falls into a black hole ends with spaghettification. However imagine there was a space-ship built out of unobtanium, that cou...
Suppose in the future (about 3-4 decades in the future), we start preferring smaller people as mates. The average size of a human would go down, maybe as far as or further than average heights from...
So far, we see an alien life form depicted based on earth type of animal kingdom, we see an insect like Zerg, a humanoid grey alien, etc. However sometimes we see alien like Guardians of galaxy's ...
What circumstances would be required for a world in which human emotions directly affected the physical world. For example, if a person grew angry, releasing a burst of electrical energy which woul...
Would a state be able (with currently available technology) to cause cancer to its enemies, which it can't silence in a different way? (e.g. staged accidents, assassinations, imprisonment) Hugo Ch...
Knowledge has come to me recently that mussels can suck up pollutants, making them crucial cleanup crews in the New York filth. This knowledge is the inspiration for this alternate scenario, in wh...
If I were to build a world like Game of Thrones, how would the dragons not burn their own nostrils from the heat of flames?

Let's imagine an Earth clone devoid of naturally occurring fissile materials"”and, for comprehensiveness' sake, also devoid of fertile materials like thorium and americium that could be used to pro...
If we made a large moon near Mars, the tidal forces would encourage the tectonic system to rev up again, and start up the inner dynamo effect. There would be volcanoes, producing a new atmosphere, ...
Suppose we detect a stellar black hole passing near the Solar system, and we have technology and time to send a manned mission to study it. Are there any experiments or observations that would hel...
Assuming that in the not too distant future space travel developed enough, that large numbers of ships and people were leaving the earth's surface on a regular basis. Would this ever reach a point ...
There are craters that are permanently dark at the Moon's poles, since the Moon's axis tilt is so small that the sun never rises above the crater rim. On the Moon these get incredibly cold, since ...
Suppose we would create a river, canal or a tube around the earth and water would flow in it. Where would it flow? And if we put some turbines in this flow, could it produce free energy?
Santa keeps his elves under horrid, appalling conditions. Working everyday of the year for little pay in the freezing cold of the North Pole. But just how many elves does he need? How many elves w...
