Which statement best defines a universal law

The law of attraction in physics Newton's gravitational pull means to lie close to each other. In the field of physics of each object with mass m1 always have attractive forces with another object (with mass m2). For example, a particle with other particles will always mutual attraction. Examples put forward by Sir Isaac Newton in the field of classical mechanics that anything on the atmosphere will be pulled by the earth, which was then known as the phenomenon of falling objects.

Attractive force of gravity is expressed by Isaac Newton via Writing in the journal Philosophiæ Naturalis Principia Mathematica on July 5, 1687 in the form of the following formula:

F = G / frac {M_1 m_2} {r ^ 2},

Where:

F is the force of gravity between the two masses,

G is the gravitational konstante,

m1 is the mass of the first object

m2 is the mass of the object, and

r is the distance between the two masses.

This theory is then developed further that any celestial body will be mutual attraction, and this could explain why the earth should revolve around the sun to offset the attractive force of gravity of the earth-sun. By using the gravitational pull of this phenomenon as well, meteors closer to the Earth in its journey in space will be attracted fall to earth.
