'''The theory of Gravity''' is a [[Naturalism|naturalistic]] explanation for the mutual attraction of particles that contain mass.  Before general relativity, gravitation was described by [[Sir Isaac Newton|Isaac Newton's]] naturalistic law of universal gravitation in his [[Philosophiæ Naturalis Principia Mathematica|''Principia Mathematica'']]. Issac Newton's current theory of gravity cannot explain the permutations of space and time as velocity of an object approaches the [[speed of light]]. [[Aristotle]], and other previous thinkers and scientists before Newton never proposed a mathematic explanation for attraction of masses.

Gravity is a natural phenomenon by which objects with mass attract one another.  Before general relativity, gravitation was described by [[Sir Isaac Newton|Isaac Newton's]] naturalistic law of universal gravitation in his [[Philosophiæ Naturalis Principia Mathematica|''Principia Mathematica'']].

Everything in the universe that has mass attracts every other thing that has mass. The mechanism which transports this force has never been observed. Scientists have postulated the existence of a hypothetical particle, the [[graviton]], in order to uphold the naturalistic explanation absent of a supernatural force.  The attraction depends on the mass of the objects and the distance between them. For normal objects, this pull is minute, but you can measure the pull between a very large object like the [[Earth]] and another object like you by standing on a scale. Your [[weight]] is the measure of the pull of gravity between you and the planet you are standing on. This [[force]] depends on your [[mass]] and the mass of that planet, but it also depends on your [[distance]] from the center of the planet. The further you are from the planet's center, the weaker the pull between it and your body. If you double your distance, the force is one quarter. At ten times the distance, the force is one hundredth. It drops off with the square of the distance. This is called the [[inverse square law]].<ref>http://hyperphysics.phy-astr.gsu.edu/hbase/forces/isq.html</ref>The force never becomes zero, no matter how far you travel.
