The General Relativity is the currently accepted theory of Gravitation in modern physics. Finding though similarities in formulas derived from other physical laws, with the well-known Newton's universal gravitational law might give us hints on some properties and the nature of the forces and matter. This paper shows that the matter might be not as much an external entity placed inside the space-time, but instead can mostly be compressed space, and from that alone arises the gravitational force. And more, it shows that with the increasing of mass in structures like Spiral Galaxies, or Filaments of Galaxies, the gravitational constant 'G' also increases. It could in part account for the Dark Matter. And in the end, presuming the initial state of the space was compressed, might also explain the expansion of the Universe.
