These points are identical and differ only in location. Let the initial point be surrounded by points. This sphere has a radius of one point but a physical length of zero. Repeat this process and let the number of these spherical layers increase ad nauseam to represent the field of Space. The physical length of all these spheres is still zero although they appear to be unending.
Space then is an expanding spherical field.
Now start the points in the outer sphere moving inward. Repeat this process with each new outer sphere and combine these points into lines. The result is a gravitational field. Gravity is a radial field of inward flowing lines. Gravity originates at the outer limit of Space.
