In another question, Are flying plants possible?, a point was raised that because of the square-cube law, a large, hollow, spherical plant could fly by having the air inside be a little bit hotter ...
Would it be practical to use a "squirrel suit" and sacs of buoyant gas for deceleration from a free fall as opposed to a parachute? Furthermore, once the sacs have been inflated, could the person i...
I know that with a vacuum, you'll be able to gain a whole lot more lift than with any gas. I'm just wondering how you'd do it. What would be needed to make a vacuum balloon as opposed to a hot-air ...
How dense would the atmosphere of a theoretical planet have it be, in relation to Earth's atmosphere, to fly with, say, a 10 to 15 foot wingspan? Math is acceptable and encouraged, and a set of art...
Is it possible to have a planet that is both bigger than Earth and weaker in terms of gravity? I've got an idea about it being less dense, but I don't know what to do about its magnetic field. I ne...
I'm wondering what adverse effects might be felt by someone from a planet with, say, 80% of Earth's gravity and a denser, but breathable, atmosphere with a higher concentration of oxygen visiting a...
Ok, so I'm making a setting where people have colonized various objects in the solar system and out of it. One thing I know I want to include to flesh it out a bit* is a sport for low-gravity envir...
Assuming an average, fully developed adult man, what sort of changes could be made to his genome that would have a noticeable effect on his mind or body? To the best of our current scientific knowl...
What would, roughly, a scientific research station look like on a gas giant? Use Saturn as a baseline. The station would float because of a "balloon" carrying nothing. Vacuum is the lifting "gas", ...
So I'm writing a story set in the close(ish) future(say 2130), and space debris is starting to be a real problem. Stations in orbit are constantly having to maneuver out of the paths of orbital deb...
So I'm writing a story that takes place in Saturn's atmosphere, and I've run into a bit of a problem. You see, I wanted it to be possible to have some pretty badass scenes with sci-fi fighter jets ...
Many fantasy stories involve some variation of a dragon, and while there's a lot of variation in whether or not they fly, if they can breathe fire, how magical they are, etc., the strength of drago...
So I'm designing a world where the air has its own ecosystem, separate from the one on the land, because sky whales are cool. However, I'm having trouble figuring out what the plants and other prod...
Would a spoked, rotating torus work as a method of colonizing space? If so, how feasible would it be? As in, what would be the cost, where would we get the materials for it, how fast does it have t...
So I'm writing a setting featuring asteroid mining à la Deep Space Industries, where the material mined is used for construction in space rather than brought to Earth. To maximize efficiency, I'm ...
