[1] [2] Some sources define a megastructure as an enormous self-supporting artificial construct. The products of megascale engineering or astroengineering are megastructures. Most megastructure designs could not be constructed with today's level of industrial technology. This makes their design examples of speculative (or exploratory) engineering.
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.
Disphenoidal or seesaw (also known as sawhorse [1]) is a type of molecular geometry where there are four bonds to a central atom with overall C 2v molecular symmetry.The name "seesaw" comes from the observation that it looks like a playground seesaw.
Megastructure is an architectural and urban concept of the post-war era, which envisions a city or an urban form that could be encased in a massive single human-made structure or a relatively small number of interconnected structures. In a megastructural project, orders and hierarchies are created with large and permanent structures supporting ...
Structure of iodine heptafluoride, an example of a molecule with the pentagonal-bipyramidal coordination geometry. In chemistry, a pentagonal bipyramid is a molecular geometry with one atom at the centre with seven ligands at the corners of a pentagonal bipyramid. A perfect pentagonal bipyramid belongs to the molecular point group D 5h.
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 ...
