Many experiments seem to demonstrate that the influence of the atomic forces (mainly gravity) disappears outside of the atoms proximity and these forces don't have relevance at long distances. This has caused the sensation that these forces don't prevail very far.
In many cases and mainly in gravity I believe this is not this way. What happens is due to the space situation of masses an effect that I call Integration Effect take place, for which in the accumulations of masses the particular gravity of each atom is integrated quickly into the total gravity of the mass. Very logic thing, since if we added all the quantum gravity of each atom, we will get a common resultant.
Therefore the gravity of each atom only acts inside its particular domain or orbital system. Outside of this particular domain what reigns is the common gravity of the mass.
However this doesn't mean that its gravitational power disappears, but rather it is added with the gravity of other atoms forming a common force for all the mass.
So, gravity of planets, stars, galaxies etc. is the sum of the gravity of their component atoms.
Then, atomic gravity reach very long distances; theoretically, till the infinite.
Besides, this circumstance has led scientists to believe in the existence of two types of attractive force in the atomic nuclei: Gravity and Strong Force.
Really Strong Force is the same gravity measured on the atoms nuclei as I explain in its corresponding chapter. Strong Force.
