The gravity is out of the matter is in the space.
The gravity is in the whole universe from the Big Bang , is everywhere at the same time.
It centers to the neighborhood of the objects , if the mass is bigger the gravity also is bigger.
The gravity is the container of the universe and his power is major that of the galaxies , because of it it moves.
The gravity is a field of force that is in the whole universe at the same time, the mass generates a tension to the neighborhood of the objects , but if the object is very big as the galaxies the tension only takes place in a side of the object , because of it the movement of the galaxies takes place towards the space , because of it the galaxies hasten.
With this theory it is possible to unify the theory of Einstein's relativity and the quantum mechanics.
