Megastructure
A megastructure (or macrostructure) is a very large artificial object, although the limits of precisely how large vary considerably. Some apply the term to any especially large or tall building. 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 exploratory engineering, speculative (or exploratory) engineering. Those that could be constructed tend to qualify as megaprojects. Examples of megaprojects are the Zuiderzee Works in the Netherlands and Burj Khalifa in Dubai, the UAE. Megastructure (planning concept), Megastructures are also an architectural concept popularized in the 1960s where a city could be encased in a single building, or a relatively small number of buildings interconnected. Such arcology concepts are popular in sci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Planet
An artificial planet (also planetary replica and replica planet) is a proposed circumstellar megastructure with sufficient mass to generate its own gravity field strong enough to prevent atmosphere from escaping, though the term has sometimes been used to describe other types of megastructures with self-sufficient ecosystems. The concept of an artificial planet appears in many works of science fiction. Science Artificial planet Mark Hempsell suggests that an artificial planet could be created in the Solar System in preparation for future space colonization, most likely in the habitable zone between the orbits of Venus and Mars. It could evolve from a smaller artificial space habitat. Its purpose would be similar to that of other megastructures intended as living spaces (such as the O'Neill cylinder) or to that of colonizing (or terraforming) existing planets. Unlike a space habitat, an artificial planet would be large enough to create its own gravity field, which would prev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
