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 created the [[graviton]], a hypothetical particle, 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 the scales. 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.

The law itself states that each particle in the [[universe]] attracts another particle with a force directly proportion|proportional to the product of their masses and inversely proportional to the [[exponentiation|square]] of the distance between them<ref>Serway and Beichner, Physics for Scientists and Engineers, Fifth Edition</ref>, or:
