Would a human being be able to run faster, jump high, etc. if the gravity on Earth weakened? I'm assuming a weaker gravitational pull would cause the muscle to deteriorate because the body no longe...
What would happen if there was two more planets beyond Pluto, one with two times the size of Pluto and another with 4× the size of Mars, I'm curious to know what effects this would have on the plan...
It's well established that the human body does not do well in zero gravity. Symptoms such as fluid loss, muscle atrophy, bone mass loss are well known. Less well known problems extend to such mun...
In relation to this question, what would plants do if they were taken from their environment to another gravity level, in particular zero g. For example would the daisy manage to grow higher bec...
The city - a modern, sterile 'utopia' (with the undercurrents of government control and suppression, of course), that can be current tech, or future tech so long as the day-to-day lives are in curr...
I've always been curious whenever I heard the mother wererabbit sings a popular folksong to the young, there is a particular line in the lyric that seems to puzzle me. It goes likes this: "up up a...
Concerning long term effects of zero gravity on humans living in space compared with those living on super earths with 1.5x to 2x G, how could the gravity differences cause reproductive failure amo...
This is a multi-tiered question. I have seen these larger questions before, but if I need to separate them out into their own questions let me know. In my story I have a machine that can manipulat...
I am wondering, what mechanism would be needed to generate gravity on a space ship in interstellar space, like we see it on Star Trek or Star Wars? What is the most realistic hypothetical way what ...
Let's say on an alien planet called Thindor, the surface gravity is 3.27 m/s2 (which is 1/3rd of Earth's). But the atmospheric pressure is only 50 kPa (which is 1/2 of Earth's). Assume the same 20/...
You go to sleep one day, and wake up on a different planet. Let's say the atmosphere of this planet has about the same composition as on Earth. Actually, this planet has pretty much all of the same...
In most star systems, planets orbit around a star. Is it possible for a planet to be so massive/heavy/dense that a star(and other planets) orbit it instead? Bonus points if the planet is also reaso...
How much would the gravitational force (on earth) have to increase to make air-travel impractical (not impossible as escape by space flight to other planets would be a nice option). But to a point ...
Without giving spoilers, this idea comes from the movie Titan A.E. How would one create an Earth-like planet in a reasonable time frame (100-250 years) that has both the gravity of Earth and a magn...
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...
As the title says, what would the universe be like if the gravitational force was 0.1% stronger but the other forces (strong and weak nuclear forces, electromagnetic force) stayed the same? Would t...
Can the gravitational pull of Earth drag the Moon into Earth's atmosphere? Likewise, can the gravitational pull of the Sun drag Earth into the Sun's atmosphere? If that can happen, what will happen...
I am doing some research for a science fiction novel. I need to have a planetary body around 10,000 km in diameter appear in the Solar System near the Earth and proceed to orbit it artificially. I ...
A super alien warrior goes training inside a gravity room. It's a room with a flat floor, but the surface gravity of the room can be modified at the push of a button. But under general relativity ...
I was experimenting with various star system designs with a gravity simulator, and one of the patterns I ended up with is best described as a planet with a very elongated elliptic orbit that itself...
Could a Manned Maneuvering Unit-type device provide a few hours of light artificial gravity* for a small person on an object with minimal gravity of its own? What sort of fuel would it need? * Com...
I heard that some scientists placed chickens under 2.5g for 6 months, and they survived. A normal human would black out at 5g. A trained astronaut could take up to 8g before blacking out. 20g woul...
Almost all of our terrestrial furniture is designed and depends on gravity. Beds to lie down in, chairs to sit down on, tables to place things on top. None of these would work in a zero-G environme...
Suppose a very large planet orbited a star or other spacial body in an oval shaped path, similar to Earth's but closer to induce a varying gravity during orbit. The planet has a large gravity wel...
Suppose one constructed a Bernal sphere, similar in design to that described in this article and this article at the National Space Society. If the sphere was simply rotated on a single axis, wou...
