Astroengineering is the extension of megascale engineering to megastructures on a stellar scale or larger,[3] such as Dyson spheres,[4] Ringworlds, and Alderson disks.
Megascale engineering often plays a major part in the plot of science fiction movies and books.
The micro-gravity environment of outer space provides several potential benefits for the engineering of these structures.
These include minimizing the loads on the structure, the availability of large quantities of raw materials in the form of asteroids, and an ample supply of energy from the Sun.
The assembly of structures more massive than a space elevator would likely involve a combination of new engineering techniques, new materials, and new technologies.
