Lesser internal Suction causes lesser internal Pressure and contraction. All substances move toward space of lesser density. This movement continues until either a common level is reached or a combination is effected at some Suction point, and a formation of greater density is established capable of withstanding external Suction and Pressure. Greater and lesser density throughout space causes an eternal penetration of substances in which Suction draws together matter and composes formations and Pressure pushes away matter and decomposes formations. Suction is the attractive force that pulls together, composes and expands.
Pressure is the repellent force that pushes away, decomposes and contracts.
All formations of every nature are subject to these forces and when the power of internal Suction and Pressure is less than the power of external Suction and Pressure decomposition takes place. Suction causes a swirling movement of substances of greater density toward the center or space with lesser density and these substances continue to swirl together until Pressure disintegrates them. The Solar System, the Earth or an electron are examples of swirling formations created and held together by Suction. The circulation of the blood demonstrates the swirling principle in man. The center of Suction and Pressure in the Solar System is the Sun.
