A Dyson Sphere is a megastructure added in the Utopia expansion, capable of producing massive amounts of energy at the cost of rendering the solar system uninhabitable, except for Habitats. A Ring World is a megastructure added in the Utopia expansion, offering a solar-system sized habitat equivalent to four massive habitable planets.
Megascale engineering (or macro-engineering) [1] is a form of exploratory engineering concerned with the construction of structures on an enormous scale. [2] Typically these structures are at least 1,000 km (620 mi) in length—in other words, at least one megameter, hence the name.
Engineering on an astronomical scale, or astronomical engineering, i.e., engineering involving operations with whole astronomical objects (planets, stars, etc.), is a known theme in science fiction, as well as a matter of recent scientific research and exploratory engineering.
In contrast with the Alderson disk, the Aysle "diskworld" works according to fantasy physics, including a "gravity plane" that bisects the disk laterally, so that opposite sides "fall" towards the plane. The diskworld of Aysle had a bobbing Sun and multiple inner layers. Both sides of the disk were inhabited, as were the internal layers.
One of the simplest examples of a stellar engine is the Shkadov thruster (named after Dr. Leonid Shkadov, who first proposed it), or a class-A stellar engine. [5] Such an engine is a stellar propulsion system, consisting of an enormous mirror/light sail—actually a massive type of solar statite large enough to classify as a megastructure—which would balance gravitational attraction towards ...
A matrioshka brain [1] [2] is a hypothetical megastructure of immense computational capacity powered by a Dyson sphere. It was proposed in 1997 by Robert J. Bradbury (1956–2011 [ 3 ] ). It is an example of a class-B stellar engine , employing the entire energy output of a star to drive computer systems. [ 4 ]
Researchers have discovered a megastructure in the Baltic Sea that was likely once used by hunter-gatherers to hunt reindeer nearly 11,000 years ago.
A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its power output. [1] [2] [3] The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's ...
