[1] O'Neill proposed the colonization of space for the 21st century, using materials extracted from the Moon and later from asteroids. [2]
In mathematics, a pointed space or based space is a topological space with a distinguished point, the basepoint. The distinguished point is just simply one particular point, picked out from the space, and given a name, such as x 0 , {\displaystyle x_{0},} that remains unchanged during subsequent discussion, and is kept track of during all ...
The word space in space architecture is referring to the outer space definition, which is from English outer and space.
