Gravity is a universal force of attraction acting between all matter.16 It exists throughout the universe. Gravity is the weakest known force in nature.16 It causes all objects to have weight.16 Gravity's force is relative to the mass of the object.16 On earth all objects are attracted to the center of the earth.16
Gravity is invisible.17 Weight is a measure of the negative force of attraction of any object having mass.17 Weight increases as the object gets closer to the center of density.17 Gravity is an integral part of and encompasses all objects that have mass.17 Gravity is a force of attraction only between objects that have mass.17 One of those objects must have unequal density to the other. The higher the density, the stronger it’s less resistance to attraction, and the faster it will move toward it. The lower the density, the weaker its strength to higher resistance to attraction, and the slower it will move toward it. Attraction is lessened by distance. Differences in densities will cause positive or negative resistance to attraction. Weight will travel to the strongest point of least resistance. The strength of resistance to attraction is equal to the distance of the object to each other and the mass and densities of each object.17
Isaac Newton held that every particle of matter in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.17A
On Earth, the highest density and its strongest attraction of Gravity is at its core. The center is thought by most scientists to be primarily composed of Iron. Every place on Earth all objects are drawn directly to that high density attractions of Gravity. Gravity affects all things throughout the Universe.
