The shell variant of a Dyson sphere consists of an artificially-made shell of material about 1 AU in radius encircling a star. The sphere captures most of the star's energy and stores it for future...
It's the future. The setting is about as "hard-ish sci-fi" as it is possible to be, with the one big exception of a viable FTL engine. Humans have began spreading out into the galaxy, colonising n...
My question is as follows - let's assume our objective function is to have as many humans as possible living outside the confines of the Earth as soon as possible. For this, we need to provide thos...
I have heard people (quite possibly on this site) say that by the time a civilization is able to make Dyson sphere it will be useless to build one for power and energy needs. So, would a civilizati...
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'm trying to create a scenario where the local star is "quickly" (suddenly up to thousands of years) removed, dimmed with reduced output, destroyed (maybe), or otherwise fundamentally changed as t...
Assume technology more advanced than current levels, let us theorise for this question that we are capable of reaching and if needed extracting material from any planet or moon / body in our solar ...
In a galaxy far far away... M6760 (I made it up) is an unusually massive neutron star billions of light years away and it is surrounded by a spherical Dyson sphere painted in new improved formula v...
I would like to destroy a Dyson Sphere so it leaves big chunks of scrap metal with no habitable zones left, but still with enough structure to hold building-sized blocks. The destruction shouldn't...
If a circular structure could be built that would wrap around the entire earth, but was of a larger radius, would it 'float' above the earths surface or would it somehow fall onto the surface at so...
In the wake of this, my answer to this question about where to put a Dyson Sphere an apparent issue came up. And it needs some good resolution: What are we going to do with all that heat the syste...
So, we've gone off to another star system and decided to build a Dyson bubble--a continuous statite, supported by radiation pressure, surrounding a star--with a surface gravity of 1g to live on. N...
On the inside of a Dyson sphere there is effectively no gravity. Is there an alternative method to keep people on the inside surface from floating around? I know it could spin and that would keep...
Would a Dyson sphere make a red dwarf appear to be a Brown Dwarf? Would it disguise a star enough to misidentify it what size it is? I'm just wondering if it could be possible that some Dyson sph...
My world is a 1AU radius, 12000km thick Dyson Sphere with 6 equally spaced holes, 4 filled with water. The two main problems I have are gravity and heat. This question concerns heat and how to stop...
I've heard several schools of thought. From a hard science standpoint, could there be gravity on the habitable surface of a Dyson Swarm plate? I keep thinking no. But if the outer shell were to b...
While there are approaches to make a habitable Dyson sphere that are technically reasonable, I am curious about what the climate would be like. For simplicity, consider a scenario where a thick she...
One of the answers to What could make a star green? describes a living Dyson sphere made of photosynthetic, plant-like material. What type of star or star system is ideal for a plant-like Dyson sp...
Asked a similar question before but didn't think it through and mangled it. Anyway would it be possible to build a structure between two star systems? Basic scenario is that you have two stars su...
Imagine that we start expanding the International Space Station until it becomes a ring encircling the whole Earth. Then we started widening the ring until it met at both poles, forming an orbital ...
Can a Dyson Sphere and a star inside of the Dyson Sphere, both have a "stable" orbit around the barycentre of a system where they are not the most massive objects? And/Or Can they both orbit togeth...
There have been several questions about the construction, operation and destruction of a Dyson sphere. I'm interested in something a bit less exciting: how far out can you still see it from? Assum...
The year is 3030 and the robots (who have replaced humanity as the dominant intelligent beings on Earth) have decided to build a Dyson sphere around the sun. They're planning on disassembling Venus...
If I have a typical Dyson sphere, around my star, it will block the light needed to live on an orbiting planet. Is there any other megastructure that can function like a Dyson Sphere, but does al...
I'm building a Dyson sphere - a real one, like Freeman Dyson originally proposed, made of swarms of solar collectors in independent orbits that fully surround the star, something like this: Each...
There was a question on here a while ago about lighting a massive Dyson sphere, that has gotten me to thinking. Obviously, such an item needs some unobtainium to build, but ignore that. I'm figur...
Let's say I have a Dyson sphere roughly the same size of the earth with a very small "star" in the center. Continents, oceans, and people inside the sphere experience a reverse gravity in the oppos...
It seems like Dyson Spheres are always brought up in the context of harvesting power. However, another use for a Dyson Sphere may be to cloak your solar system/inner planets. If the star's output d...
So let's say you have a Dyson sphere that is 5 kilometers thick . Now, it isn't solid. It's meant to be inhabited. There's the inner shell which is completely covered with solar panels and any oth...
Okay so I have a sci-fi world masquerading as a fantasy world where numerous different genetically-engineered humanoids live on nine different ringworlds orbiting an artificial Earth-mass black hol...
A Dyson Sphere, being a sphere, is a uniform "equatorial" climate across the entire surface. I consider this to be a major problem. Somewhere between the Dyson Sphere and the Dyson Hyperboloid is ...
Note: There is a related question about illuminating such a sphere that inspired this question. I'm going much farther, though, this is not a dupe. The Dyson sphere will be the central mass of t...
Humanity survives long enough to create a Dyson-Ring around old Sol using many of the planets and asteroids currently in the system. Then 'something happens' we die out, we discover a way to trave...
Kinda inspired by the non-disappearing ship question, but I actually asked this particular question on an unrelated forum a few years ago. Reposting it here (well, paraphrasing, really, since I don...
Summary version: So we're talking people living on top of 30 miles of topsoil, fake dino fossils and water on the outer surface on a hollow (but sturdy) unobtanium sphere with a radius about 1 AU....
