What is Gravity ? Everybody would say "It is the force the Earth exerts upon us so we do not go flying off into space by centrifugal force". Not scientifically good enough.

Newton's law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between the two bodies.

Newton`s 3rd law of motion states ;-
For every action there is an equal and opposite reaction.

Is that good enough ? No.

Why does an inert mass possess an inherent gravitational force and how is this force generated from gaseous or rocky material ? Where does the energy come from in an object which is not capable of generating a force?

After all, masses are just masses and forces have to be generated : F=MxAcceleration, so where does that leave all the many Trillions of bodies which comprise our Universe in conforming to Newtons 3rd law of motion ?

Gravity still remains one of the biggest mysteries of physics and the biggest obstacle to a universal theory that describes the functions of every interaction in the Universe accurately.

If you think you can shed some light on this, please post your comments.
