This is the second part of a question here that I've broken up because they are two very distinct problems. Assuming a perfectly stable ringworld: Assume a more traditional flat ringworld that is ...
When I was a kid, I read an essay by Asimov describing an inside-out asteroid: (summary from Wikipedia) The Bubbleworld or Inside/Outside concept was originated by Dandridge M. Cole in 1964....
My question is as the title put it. I would like to know how large and thick of a wall we could currently construct. Given we have no limitations in money or materials. Bonus if it's actually sturd...
Suppose that Khufu, pharaoh of Egypt and builder of the Great Pyramid of Giza, was introduced to the idea of an amusement park. More specifically, suppose that he was visited by a time traveler a...
Thanks to the recent discovery of handwavium "¡ filaments that can in principle be extruded to any length, we will be able to build space elevators sooner than most people would expect. The inte...
One of my more brilliant characters is taking a terraforming class and at one point, early in the story, she has to leave the action to take an exam. The question presented in that scene is listed...
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...
Assuming you already had sufficient money and resources to build a tower stretching from the top of Europa's ice layer down to the bottom of the seabed, could you build it on top of one of its geys...
Think basically a Jupiter brain (a megascale computer made from a gas giant) but with a Dyson shell surrounding it to act as a threefold nutrient/waste exchange (assuming it repairs itself and adds...
If force fields haven't been invented and ships must be able to deploy and return too fast for doors, how might a capital ship be able to protect its hangar from space debris and opposing fighters
Following on from this question: Can Cloud Nine be built? Let us assume we have constructed a Cloud Nine tensegrity sphere with a 2 kilometer diameter out of a durable material for use in Earth's ...
Imagine a SupraWorld being built around a gas giant like Jupiter. To have a 1g gravity on the surface the resulting SupraWorld would have to be less than twice the radius of the giant (my calculati...
We have all heard about the idea of space elevators, a cable so long that it literally reaches into outer space, to be used for launching payloads cheaply into Earth and interplanetary orbits. Howe...
Is living on an Alderson Disk possible? An Alderson Disk is a large CD-like megastructure, with a star in the center. If the disk is thick enough, it could have its own gravity. Also, the star in t...
Would something like this be feasible? Span of bridge is approximately 5km. Height above canyon floor is approximately 800 meters (1/2 mile). Bridge structurally close to neutral. Tethered dirigi...
It finally happened. The inhabitants of Metropolis, the capital of Our Nation, have finally had enough of the swampy lands, suffocating summers, freezing winters, spring floods, risk of surprise in...
If some advanced race were to make a solid opaque shell around our Sun, say around Mercury's orbit, something like a Dyson Sphere, how long would it take for Earth to freeze over and end most life?
A Dyson Laser would be a spherical swarm megastructure arrangement of robots focusing mirrors directing sunlight towards a particular planet in a system heating it with enough energy to melt it. T...
I am currently designing a megastructure which is supposed to provide living- and workplaces for about 100.000 people. It is supposed to be designed in a way that it provides everything the inhabit...
