or:Why gravity exists?

or:In modern physics, gravity is most accurately described by the general theory of relativity (proposed by Einstein) which describes gravity as a consequence of the curvature of spacetime. For most applications gravity is well approximated by Newton's law of universal gravitation, which postulates that the gravitational force of two bodies of mass is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
