All suns are generated into incandescence by two black rivers of evacuated light which flow centripetally inward toward their still centers by the way of their poles. Conversely, darkness of space is radiated from two incandescent rivers of white light which flow centrifugally from suns' equators. (Fig. 35)

Thus are the four arms of all spiral nebulae formed as two pairs of opposites interchanging with each other to become the other two; the two black arms belong to gravity and the two white ones to vacuity. (Figs. 36, 37, 38)

This electric universe is curved - motion is spiral. Where motion ceases, curvature ceases. Cleavages between wave field boundary planes of crystals separate them into their individual crystal forms. Motion cannot pass through those planes, for there is naught but stillness there. Motion is repeated in all wave fields by reflected extension from wave field boundary planes.

Curvature is imperative under such conditions for opposed pressures resist each other and each must bend to the other to find passage for its own expression of force. Motion and curvature simultaneously begin and end when opposition begins and ends. (Zero in Fig. 39)

Each wave field is like a separate projection machine in which its own curved motion picture universe is dually projected upon its self-measured zero screen of space. (A in Fig. 39). The incandescent sphere of light which centers it?pictures the forms of desire in the measure of desire for manifestation. (See also Fig. 38)

This curved universe consists of lenses and mirrors of light which reflect, bend, curve, concentrate and decentrate light into its countless forms. Any action anywhere is repeated everywhere by and through countless mirror planes of wave fields and the lenses of space. (Figs. 40, 41)

Concentrated spheres, such as the earth and sun, are surrounded by layers of light of equal pressures. Clouds float around the earth in them. The reason they float in curves parallel to the earth is because of these spherical equipotential planes of pressures which curve as the earth curves.

Curved pressures of light act as lenses to multiply and divide light radially. Light rays which pass through curved planes concentrate toward a point when projected through light lenses of space in the convex direction and decentrate when they pass through in the concave direction. (Figs. 42, 43)

Gravity and radiativity are accounted for by this fact. Every object which falls toward the earth falls radially toward its center because of this fact. No two men who stand upright in balance with gravity stand parallel to each other. Lines drawn through the feet and head of any two men standing in either hemisphere would form a cone with its base in the heavens and its apex at earth's center. Rain falling vertically from a cloud falls conically. The area of the base of the cone in the cloud is greater than its conical measurement on the earth (Figs. 44, 45).

The electric potential of rain increases as it falls because of the multiplication of pressures by the lenses of light which surround the earth. For the same reason a man weighs less as he ascends a mountain and regains it when descending. Light lenses subtract from his potential by multiplying its volume while he ascends and multiplies it while he descends by subtracting from its volume while he ascends and multiplies it while he descends by subtracting from its volume.

Curvature of light wave axes, by contraction or expansion between planes of zero curvature is the cause of all pressures; all pattern; all of the attributes of matter, such as density, tenuity, melting point, brittleness, conductivity and countless other effects which are voided when curvature ceases in planes of rest in wave field boundaries, or in points of rest around which motion rotates spirally.
