A Mega-Shipyard is a massive shipyard in orbit of a star, capable of producing ships much faster than average shipyards. The Aetherophasic Engine is a megastructure built by crisis aspirants, capable of destroying the entire galaxy as a side-product of allowing the race which constructed it to ascend to the "Shroud", an alternate dimension in ...
CfA2 Great Wall (1989) 750,000,000: Also known as the Coma Wall. Saraswati Supercluster: 652,000,000 [22] The Saraswati Supercluster consists of 43 massive galaxy clusters, which include Abell 2361 and ZWCl 2341.1+0000. Boötes Supercluster: 620,000,000: Horologium-Reticulum Supercluster (2005) 550,000,000: Also known as the Horologium ...
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.
The Great Wall (also called Coma Wall), sometimes specifically referred to as the CfA2 Great Wall, is an immense galaxy filament. It is one of the largest known superstructures in the observable universe .
Megalithic walls Also called Cyclopean walls [11] Stone circles In most languages stone circles are called "cromlechs" (a word in the Welsh language); the word "cromlech" is sometimes used with that meaning in English. Dolmen A dolmen is a stone table, consisting of a wide stone supported by several other stones [12] Cist
In engineering, macro-engineering (alternatively known as mega engineering) is the implementation of large-scale design projects. It can be seen as a branch of civil engineering or structural engineering applied on a large landmass. In particular, macro-engineering is the process of marshaling and managing of resources and technology on a large ...
The Sloan Great Wall is between 1.8–2.7 times longer than the CfA2 Great Wall of galaxies (discovered by Margaret Geller and John Huchra of Harvard University in 1989). [2] It also contains several galactic superclusters, the largest and richest of which is named SCl 126. This is located in the highest density region of the structure. [3] [4]
Very large pontoon-type floating structures are often called ‘mega-floats'. As a rule, the mega-float is a floating structure having at least one length dimension greater than 60 metres (200 ft) Horizontally large floating structures can be from 500 to 5,000 metres (1,600 to 16,400 ft) in length and 100 to 1,000 metres (330 to 3,280 ft) in ...
