I'm fairly new to the idea of writing.... anything, and I was asked to make a character to insert in a friend's world. I am trying to create a fictional character that has the power of manipulati...
I've looked for an answer for this, but the only information I could find dealt with the ring itself. All I want to know is what would change on the Earth if all problems were solved and the ring w...
It has been determined by observation of the stars that the gravity on Flat Earth is due to it accelerating upwards at 1G. This is what holds people and objects to the surface. It has also been det...
I have a colonized asteroid that is roughly spherical and has been hollowed out. To create artificial gravity I spin the asteroid creating a strip of 1g gravity around the "equator". What would hap...
I have a spherical spaceship that is about 2 kilometers in diameter with an outer clear, yet strong shell. This spaceship is largely made up of empty space occupied by air. Aside from this the spac...
I'm trying to create a system where a gas giant has two moons in binary orbit with each other. I'm trying to get that James Cameron look with the gas giant on the horizon, but also have a equally s...
I'm writing a speculative fiction story that includes superhumans, and I'm trying to get some of the specifics nailed down. Several of my superhumans have the typical powers of flight, usually able...
I'm not sure if it's even feasible, but I have a server farm in my book, of a size that puts it on par with Google's. I want to wipe out all the data stored on the hard drives, without destroying ...
My fantasy world is slightly larger than earth so that discovery of the continents becomes harder (about 20% surface should do it). But at the same time I want to preserve most aspects to make it l...
Suppose we begin to colonize the moon. Assuming the building materials and biological material are all imported (not taken on-site), would it be possible for the moon to become massive enough to fa...
The problem is the following: let's say we have a miniaturized satellite*, X; we know its position, velocity, acceleration, the forces applied at any given moment; we also know its mass, its d...
What kind of destruction would it cause? I'm assuming it'd be rather significant, could it shatter a tectonic plate? The crust? How would the oceans fare? Would the planet be able to catch the proj...
CONTEXT and INTRODUCTION Humans establish colonies on Mars with slightly more advanced technology than we have today. The Martian colonists lose all contact with Earth. Over centuries, the Martian...
From what I know about the Heisenberg Uncertainty Principle, one of its consequences is that when you learn a great deal about the position of a particle, you greatly increase the uncertainty of th...
[Edit: I'm not looking for 100% realism. I'm looking for an explanation as realistic as possible, possible with just few exceptions to physics.] [Edit 2: In my imagination these worlds are differe...
Warning This question is one of a series about specific use of teleportation. It will concern only about pressure and atmosphere. Here are previous question: Teleportation and speed Context T...
I am dealing with a dystopian story that tries to come up with some kind of total surveillence or control from higher authorities. The authorities threaten to kill those who disobey them by simply...
READ EDITS I am writing a passage about the main character of my book travelling up a space elevator to the spaceport that rests in geostationary orbit above Mars. This means that the elevator wou...
There are several previous questions concerning concentric shells. I won't reference them here because this is different. I understand that there is no gravitational effect inside a concentric she...
If there was a city using antigrav to maintain a position over Kolkata, and it had approximately the area of New York City (roughly 300 square miles, or 780 square kilometers), what altitude would ...
Scenario: While poking around in an alien ruin, scientists discover a gateway which offers instant transportation to an Earth-like world. The Observed World: The gateway leads to an area that is ...
I knew that energy is a scalar quantity, so I wonder can a character move and alter direction of an object at distance by giving it kinetic energy? Thanks.
What would be the diameter and rotational speed of an O'Neill cylinder on the inside surface of which centrifugal and coriolis forces are equal to "gravity" and coriolis force on the surface of Ear...
As you look at the properties of the atmosphere as you scale up or down, things get weirder and weirder. One good example is the fairyfly and its environment. Fairyflies are so small that at their ...
How can I predict the color of the sky based on the information provided? Atmospheric composition: | 2% Trace gases | 58% Nitrogen | 26% Oxygen | 11% Argon | 3% Carbon dioxide | Average s...
Supposing we had many thousands of antimatter bombs (they can be detonated in many different locations), how much total antimatter would we need in order to wipe out all humans on Earth? Supposing...
In a galaxy far far away, during a fit of inspiration for a super massive marvel of technology, the Imperator dedicates an astounding 10% of energy and materials from his civilization's dyson spher...
In my universe technology is advanced enough to have non-jet and non-rocket booster technology. For a disc shaped UFO all of the technology is crammed in the ship and there was no more room left ...
The 12 planets in my solar system orbit the G-type star of Nemo. It's about nine-tenths of the size of the sun, and has a stellar luminosity of 0.67 L☉, a diameter of 1.28 million kilometres, a s...
I just wanna ask which option requires more destructive energy? Option 1 : destroying a planet like earth to rubble (tiny pieces of rocks) Or Option 2: splitting a planet like earth in halves ...
In series such as the Hyperion Cantos and Ender's Game, there exist fictional faster-than-light communication systems allowing either instantaneous, or near-instantaneous transmission of informatio...
I remember playing this game back in 2010-2011, and In minecraft if you found a waterfall you could actually swim it up vertically, it was difficult but possible. Does this apply to real life to...
Setting is 20 minutes into future - everything is as we know it, or as we can reasonably predict, except the zero-tau capsules. Capsule is a thin mesh of Unobtanium connected to a portable Handwav...
With a powered-by-phlebotinum (ergo very handy, very powerful) rifle, I am able to shoot high-energy beams which, in turn, can pulverize anything in their path in a considerable radius. The beams c...
The TRAPPIST-1 planets are all very close to each other and thus are subjected to strong gravitational forces amongst each other and to the red dwarf they're orbiting. Would it be possible for them...
What is surface to weight ratio needed to help slow the decent onto Mars? Assembled and inflated in space could a blimp be big enough to include everything needed to jump start a colony and land...
In my story, a portal is opened from the Earth to an alternate world. However, this world is toroidal in shape and has a surface gravity equal to that of Earth. It rotates around an axis that goes ...
Ok, I get it, me dumb, you smart. Only smart questions allowed. In any case I'm going to leave the question unaltered in case some others might get something out of the answers. Thanks to everyon...
So my story is set in the TRAPPIST-1-system and a rogue planet enters the system. When it's still far off, a scientist discovers that one of the numbers is slightly off. (She has some tables that p...
Inspired by this question regarding reality as simulation and this question about a continuous time line, it made me wonder: if our time were indeed like a high frame-rate simulation, how could we ...
The question stems from watching a scene from ID2 and seeing the massive alien mothership landing/crashing on the North Atlantic. What mass would a starship, or any other artificial object constru...
Let's assume, without revoking any of today's science, that the world is a simulation. What would a bug look like? I'm assuming that "the eiffel tower suddenly being bent at 45°" is rather unlik...
The subterranean nation of Glot has developed the ability to "thermally link" two equally sized diamonds, such that they are always the same temperature, regardless of spatial separation. We can c...
PREMISE The zone will make all electrons disappear. QUESTIONS If a person walks in that zone with his whole body, would he die from heart failure? What happens if he just sticks his hand in? H...
This follows another question that brought me some curiousity about the general state of an earth-like moon tidally locked to a gas giant planet. There's been questions about a world tidally locke...
I ran across this article today about how moons might have moons. In Daniel Keys Moran's universe, an Earth-sized planet named November orbits a gas giant named Prometheus. November is inhabited,...
So, in my research and preparation for the question I asked immediately before this one, I was introduced to the concept of "fluffy" gas giants, gas giants with significantly lower density than wou...
Premise: Earth has a magical cataclysm that pulls up new mountains, pushes down parts of landmasses, and generally reshapes Europe enough to make it unrecognizable (to the average person looking at...
In my particular scenario, There is an habitable exoplanet in which the axial tilt turns to always face the system's star, and the planet is not in tidal lock, this allows for a certain range o...
My current WIP involves an athletics competition on a non-terraformed moon, namely the Earth's moon. And while it would be a bit difficult to play certain sports without a breathable atmosphere, th...
