Possibly the most influential formulation of a theory of gunky spacetime comes from A. N. Whitehead in his seminal work Process and Reality. Whitehead argues that there are no point regions of space and that every region of space has some three-dimensional extension. Under a Whiteheadian conception of spacetime, points, lines, planes, and other less-than-three-dimensional objects are constructed out of a method of "extensive abstraction", in which points, lines, and planes are identified with infinitely converging abstract sets of nested extended regions.
