I had posted a question a couple of days ago asking if it would be possible for an artificial satellite/cosmic body at the L1 orbit to block out the Sun, but the logistics of that is a little too e...
In the universe of my story, the Earth is ridden with metahumans with uncanny powers that do all sorts of different things. Of course, to do all this, they would require a tremendous amount of ener...
Basically, in a sci-fi roleplaying group I am apart of, I have began to work on a long-standing human colony world. The tech-level is pretty much bog-standard sci-fi, and such, colonisation is poss...
Is it possible for humans to survive on the surface of the Earth, assuming the Sun was, for some reason, not emitting any light/heat/other radiation? Would whether the Sun was actually present affe...
The Dyson Swarm is common in sci fi as an energy source, and sometimes also as a powerful weapon. As it is commonly understood, it harnesses the energy of the sun, which stores a vast amount of ene...
I've been thinking about a fantasy setting built around the idea of a habitable, tidally-locked world orbiting a red dwarf. Since it is fantasy I do have some leeway in terms of the real world limi...
In continuation of my previous question, I'm wondering about the colour of a flat world's sky. To recap the previous question, I'm imagining a flat world with the sun fixed relatively low above th...
Humans (even programmers :-) ) are used to having some access to natural light, but in a colony in space, on the dark side of a tidally-locked planet, or underground (for example) this won't happen...
Part of the Anatomically Correct series of questions. Due to the nature of Superman having so many different powers, I wanted to focus specifically on one aspect of his character: the ability to...
The cylinder is 32 km long in total, 8 km in diameter, with 3km long endcaps, resulting in a habital area with a length of 26 km (= and an area of cirka 754 km2). The main body of the cylinder is...
I am writing a sci fi novel in which one of the primary factions is a lost space colony sent to Proxima Centauri (Alpha Centauri C) roughly 350 years prior on a generation ship. The trip took rough...
Fact 1: The cause of a sunset is from the angle of the sunlight, because the amount of scattering increases as the light passes through more and more of the atmosphere. Fact 2: Higher frequency ...
We are developing a game setting and, while discussing certain aspects of the it, have stumbled upon our inability to adequately account for some phenomena due to our lack of knowledge. The thing i...
So, I have been watching a lot of flat-earth debunking videos on YouTube, which has tickled my world-building bone. So, I'm imagining a world with a sphere of sunlight-level luminosity hanging rela...
My planet (I'll call it $P$ for practical reasons) is 2 AU from the Sun, a distance in which it receives 25 % of the sunlight that Earth receives. This can be estimated with the Inverse Square Law:...
One proposed type of desert planet is one in which the equator and the "tropics" are harsh, hot deserts, but the polar regions are temperate, habitable, and lush with life. You can see an example o...
What I'm using your information for: My planet is small, has a thicker atmosphere than earth and it's orbiting a white dwarf. The main reason I chose it to be a white dwarf is that I read somewher...
In my story, there is an Earth-sized planet orbiting a red dwarf, tidally locked to its parent star, with large oceans like Earth, two moons similar to ours and a thick atmosphere to distribute hea...
Taken from this fascinating answer: The Sun is immensely loud. The surface generates thousands to tens of thousands of watts of sound power for every square meter. That's something like 10x...
What would happen if the entire inner surface of a Dyson sphere (not necessarily a solid shell, maybe a very dense swarm) would be coated into a highly reflective material? Let's say it can reflec...
Set at the present day Earth, the daylight on average is ten times as bright as today, approximately 111,000 lux at noon for example and subject to geographic and the air quality etc. I am looking ...
In my galaxy, I need a planet that is far enough away from its star to be relatively cold compared to Earth, but not so cold that liquid water cold not exist. The planet has 2 continents, 1 northe...
Basically, a sun-synchronous orbit is where one side of an object is always facing a star as it revolves around it (much like our Moon is, which is where the phrase 'dark side of the moon' originat...
How do I figure out the temperatures of certain latitudes on a planet with factors such as sunlight and the emission of heat and energy from a planet's interior? Assume the planet is smaller than E...
I've been experimenting with a fantasy world that is flat, with the sun fixed in place over the centre. The day-night cycle is provided by the sun dimming and then brightening again. Most of the re...
I am interested in a character or race of humanoids similar to the green man in the tent in Wolfe's Book of the New Sun. What qualities would the Sun need to have in order to support a race of hu...
I've been toying with a concept for a hollow/inner Earth universe in which I would like to achieve an even distribution of light. The pickle is that the "sun" of this world operates like a beacon/s...
One major problem with living underground is you lose all of that wonderful energy provided by the sun. This energy is useful for many things including growing plants for food. A window is effectiv...
So recently I got slated for missing some glaring obvious flaws in my story on here, which I really do appreciate. I'm approaching the question from a different angle though, in two parts. What w...
Tangentially related to The evolution of neon kittens Is is possible for a star to radiate in the ultra violet spectrum but not much in the visible light spectrum? If not, is there any mechanism ...
Suppose humans of the late 21st century or beyond began constructing a solar shield as a solution to climate change. Suppose for some reason (open to suggestions) they choose to build the shield in...
I saw this question here: Can I have wind turbines on my base? and someone else asked about how the planet can have 60-100mph winds without very much sunlight to cause the energy differential, to w...
I'm working on a planet and I want to know what is the maximum amount of sunlight my planet gets in lux (for Earth It's 120000 lux). My planet orbits an M4V class red dwarf that has a mass of 0.2...
Other posts from this thread will be posted here: How to make an Earth with 27 suns work (Closed as a duplicate of the follow up, Attempt Two) How To Make an Earth with 27 Suns Work, Attempt Two...
I'm creating various artificial Time Bubbles in my universe where time flows faster or slower inside a specified area, typically depicted as a semi-transparent bubble. Before developing any more st...
Background story: Current Earth, in the close future. Astronomers have found first signs of extraterrestrial life: huge sheet-like objects (with surfaces easily as large as the surface of the Eart...
What I'm thinking for this question is that some kind of filter is put around the sun by aliens that prevents some kinds of solar energy from passing through but allows other types. Like if it sto...
One of the things that affects the color of the sky is the wavelengths of light that the star emits, like the image in this question. Here is the image again: If you are standing on a circumbina...
So essentially in my story, aliens put something around the sun that doesn't stop all the light from it hitting Earth, but only some of it, effectively dimming the light without outright extinguish...
I've been thinking of using a binary model (a planet that rotates around two suns) for a possible story. The specific model is a S-type planetary system, where the planet orbits the the primary st...
I'm curious if it's possible for human life to survive in both of the following cases: 1. A fantasy world with only sunlight (no night). 2. A fantasy world with only night (no day). Note: let's ...
(See diagram) Presupposing that a Rocheworld can even exist... I imagine that sunlight would work more or less the same in the atmosphere of any part of an Earth like planet that was tidally lock...
Is there a way to induce a solar flare / coronal mass ejection (CME)? For instance, could a very tight glob of charged particles reconfigure the the Sun's corona leading to this type of event? Is ...
Suns are stars. They are orbited by planets, and sometimes other stars. Planets are orbited by moons. Reasonably advanced civilizations may launch artificial satellites into orbits around their pla...
I saw this video, and I'm curious what color bark would be if the sun was in one position constantly. The video explains that birch trees are white because of stuff in their bark. The reason is be...
Assumptions One habitable world in each system (blue sun system and yellow sun system). The two worlds are fundamentally Earth-like. The native humanoid species on each world are genetically comp...
There seems to be a connection between orbital revolution (one year) and distance from the star the body orbits. For example, Earth orbits the sun at a distance of 93 million miles and completes o...
I have a homebrew setting with a moon that has some specific features orbiting an Earth sized planet, and I'm trying to find out how these features would affect how the moon looks from the surface ...
The light from the sun is dissipated in a sphere, so there is a squared relationship between the distance from the sun. Would it be possible to place either a lens or solar collectors with a laser...
The vast majority of the sun's energy is wasted -- the light and warmth are sent out in a spherical shape, and the planets only pick up those little bits of energy that happen to be going in the ri...
