My empire's flagship, the Persecutor class UJBHE1 Abhorrent, rides into the home system of my greatest enemy, Baron Obsequious, levels its Death Ray2 at his beloved home, and pulls the trigger.3 B...
So, I was reading this article about how difficult it would be for any alien race to escape an exoplanet with about 10 times the mass of Earth. It states they probably would even lack satellites. ...
The development of microgravity cuisine is an interesting topic, especially when it comes to transferring simple processes like the successful thermochemical processing of muscle tissues (e.g. barb...
Is a planet with varying fields of gravity possible? Yes. Earth has varying gravitational fields at various different times due to various factors, mainly location based. How extreme can I make th...
I am building an idea for a terraformed environment with 1/6 the gravity of Earth, with a permanent human colony that has been established and sustained for 40+ years. I have thrown around a few id...
I totally get why humans who have colonised a low gravity environment (Mars or an asteroid, for instance) are skinny. Muscles doing less work, square cube law, force output of a muscle proportional...
I have a character on the surface of Enceladus, one of the moons of Saturn. It has an icy surface on top of what is believed to be a liquid ocean. There is no atmosphere, though near its south po...
Suppose that humanity has spread out through space. Humans are exploring all kinds of environments, including some with gravity much weaker than our Moon's: Ceres (surface gravity $=0.28 m/s^2$) ...
Beforehand: I must excuse my english. It's not my native language. Neither take this question too seriously. It's a stupid concept and I don't think that I will keep it by. It's just very "cool" t...
I'm writing a story about a group of humans (or humanoid people) that are living on a spaceship that's orbiting a planet with high gravity; the force is too much for direct human involvement. There...
There was an orbital station; a huge torus, as known from sci-fi. It was a luxurious place for people from dusty planets to relax at, and spend hard-earned money in environments resembling Earth fr...
So, I've got a planet that's basically a junkyard. It's just one big junkyard. People from various space-faring societies dump all the crap there that they don't want to deal with. Derelict spacesh...
I am trying to create a planet with low gravity that keeps an atmosphere and has an ocean that covers the whole planet. Basically I am developing beings (separately from this question) who can live...
Let's assume the planet has only one half the mass of the moon and is covered by shallow ocean. To eliminate water pressure at extreme depths, assume the ocean is also quite shallow, with a maximum...
Some of what I read in How could a 4D organism influence events in our world made me think in a different direction about a question I asked before. I'm trying to create a large sphere shaped fiel...
I was reading this article from NASA about chemical rockets and they argue that, with a planet 50% larger than the Earth (assuming similar density, about 1.5G surface gravity), it would be impossib...
I was wondering what would happen if you dug to the center of the earth. Would you get stuck in an infinite gravitational pull loop, or would you just simply get torn in between the two pulls? Yes,...
Another user's answer to a recent question, specifically the way it was worded, gave me a vision I cannot shake. Our intrepid adventurer, Joe A. Venture, is making his way through a subterranean n...
The relationship between the distance, $d$, of the event horizon from a black hole's center and the tidal acceleration, $a$, experienced by an object near a black hole allows for scenarios in which...
So, I don't believe that the "angelic" type winged human can exist (y'know, the kind with the feathery wings sprouting from the back). Too many problems of anatomy, weight, etc. But I am trying to ...
The idea is in a world with 2x the gravity (which follows from 2x the size), gravity would have less an impact in the oceans. Does that follow?
In my world, similar to our earth, a person has the ability to create gravitational "spheres". He can: modify its location vary the force move the sphere (once created) select what or ...
In a Rocheworld scenario where two planets are tidally locked and share an atmosphere, but where both the planets are so small that their gravity is very little (as low as one of the dwarf planets ...
Edit: Before I give up on this I wonder how could an advanced civilization create conditions on a small planetoid (Ceres sized?) to keep an Earth level breathable atmosphere? It seems like its impo...
(Please see diagrams) This is a question regarding an area of a Rocheworld scenario that I haven't found anything on. It is suggested that the OUT side of a planet that is tidally locked with an...
So, I created a planet that has a civilization that is beyond advanced. The planet's radius is 10x the radius of Earth, and is has the same density as Earth. What issues would I have with the grav...
I'm inspired by this question and was thinking that it is nigh impossible for sun, moon and star to exist in this world and even if they do, there is no way to sun and moon to orbit and create day-...
Let's say we have a micro-gravity environment where people are staying afloat in the air because they have wings or some other means of resisting the low gravity, but then for some reason they find...
There are a lot of solutions for living in low gravity environments. (e.g. centripetal acceleration, linear thrust, etc.) But what about living on high gravity planets? Is there anyway to build or...
Some research, and some answers from others, have suggested that a massive (planet sized?) sphere of gas in space, with no hard core, but breathable air inside some part of it, can create enough of...
I'm trying to create a massive contained zero-g environment that can sustain many life-forms including humans. The research that I'm doing doesn't make it look good. Seems like we just need gravity...
I want to create a gas giant planet. The parameters I would like for it to have are: It should have a large layer of gas within its atmosphere that living creatures including humans can survive an...
In the year 2588, ISRO (Indian Space Research Organization) along with collaboration of NASA had discovered a new planet named Accio several light years farther than Pluto. Scientists have computed...
The interior of this particular Dyson Sphere is so large that it encapsulates a star at its center. Otherwise it is filled with breathable air which creatures can breath and fly in. I imagine that ...
What would happen to a planet if its core suddenly disappeared? I'm talking instantly and without warning, gone. I'm not concerned with how scientifically accurate this would be, because I'm absol...
The Background: It's the year 4000 (or whatever), and mankind has cheated FTL travel. As a result of this 'cheating' rather than solving, however, they can't easily go beyond their borders. Howe...
OK, so humanity is going to space, and they are going to take farm animals into space, not only humans on earth value meat, but humans in space do, too. However, they don't want to waste precious r...
If we want to be realistic, we imagine ships pushing stuff out the back and relying on the conservation of momentum to move forward. Gravitational waves carry momentum. Are they viable as a kind o...
So, I know that on the planet earth, the force of gravity is actually slightly less nearer the equator, due to the Centrifugal Centripetal Spinny Force. Not by a whole lot, but by some small amount...
I'm thinking a planet orbiting a nearby star colonized by human settlers sometime in the not near, but not too distant future. How small could a planet be while still standing in as a relatively c...
I'm trying to come up with a the most economical design for artificial gravity. The simplest design for a space ship is to have a spinning ring structure around a central body. People living in the...
Let's say an intelligent civilization of beings capable of building planetary superstructures created an artificial planet with a solid core capable of generating a gravity well and covered the sur...
I know that light can be affected by gravity. But what if there was a planet where if you shone a light in a direction and it could hit your back. I'm talking about a planet where light is bent aro...
I create a world having three moons. Since precession cycle is influenced by our moon, how do I calculate the duration of the cycle with three moons? Thanks
Imagine an earth-like planet on which gravity is reduced by 20%-30% every 15 months. The low-grav-effect should start slowly, reaching its peak/bottom of round about 0.7 g after 6 weeks and should ...
In a fictional setting, an Earth-like planet is orbiting another, Jupiter-like planet. For explanation see my previous question Which astronomical or cosmological event would explain periodical lo...
Assume we have a planet similar to earth in size and materials. But we put it in orbit of a mass much greater then our sun so that the year becomes much shorter like 10 days (or put it much closer ...
For this question, assume that the planet is Earth-like in almost every way, and is in a system like ours...the distance from the sun, orbital period, rotation, axial tilt, etc is all pretty much t...
I will be writing a short story about humans landing on an earth-like forest planet with a gravitational force of about 3 meters per second squared (In contrast, Earth has a gravitational accelerat...
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 ...
