The paper is divided in two parts. The main concept of the first part is that warping of space is provoked by the particles emitted by the masses, but not because their interactions (not because the energy or momentum of these emitted particles), but instead, due to the space they occupy (they create). The new space occupied/created by these particles warps space. In the article, it is calculated that the Schwarzschild metric (compared with the Euclidean metric) creates space in a ( 21 r) distribution, the same distribution of the particles emitted by the masses. So it is considered the possibility that this new space appears, due to the new space occupied (created) by these emitted particles. According to this, when a mass increases, it should increase the space occupied by the particles emitted, so the warping is proportional to the mass. In the second part, it is calculated that the space occupied by the photons emitted by a body is proportional to the mass of the body that emits them. This makes them a possible candidate to be the transmittals of the warping of space. When the mass increases, the space emitted by it should increase in the same proportion (to increase also the warping). In the second part it is shown that the space occupied by the photons emitted by a mass follows this rule. This means, the space occupied by the photons would transmit the space created by the Schwarzschild metric, consequently its warping and consequently the gravitational field. Independently, the energy and momentum of the photons (their interactions) would transmit the electromagnetic field
