The nature of this Space Settlement was to act as a mediating structure for future explorations. The idea was simple. Earth need not be an isolated singularity for humankind, but to have another settlement at L4: TK7L4 Trojan. The initial phase would house thousands of people and later millions. In order for the asteroid to become a settlement, it was first worked on as a site. A number of surfaces as platforms were created for further resource extraction and for the production of life. In the 1960s, a small group at NASA had already worked out all the required engineering to precise detail, calculated required atmospheric compositions, and necessary calculations to create artificial gravity through centrifugal force. A large number of engineers, architects, designers, botanists, were brought together for the design and construction of this new settlement. A large artificial construct - a Megastructure was now underway.
The Megastructure was designed as a Distributed System. The design was along the lines of Brownian trees. These were the beginning of mathematical models of dendritic structures associated with the physical process known as diffusion-limited aggregation. A seed (asteroid surface and the shell, an artificial human construct), an initial position (a location in space), and a moving algorithm became the basis of the design. This made it possible for the addition of indefinite worlds as extensibility in space and time. This Megastructure had no outline or contour; an ever-changing pattern!
