Abstract
Here I show that we are able to consider a large value for the gravitational constant, G, at the vicinity of matter (r<1Å). Today physics and chemistry extremely need to this choice. The large value of G causes significant results in physics and chemistry. By considering a large value for G, at the vicinity of matter, the stability of atom and atomic and molecular bonds can be explained by a different method. Moreover, here I prove that the value of vacuum permittivity, at the vicinity of a charged particle (r<1Å), is larger than its present value and the Spacetime lines interact with electric field lines. Also, I obtain a new equation (not a new value) for a very important constant, namely fine-structure constant, with the presence of the gravitational constant, G.
