Dr. Xien tells Radu that everything that manifests in the material plane, from the biggest to the smallest, is born because of an energetic vortex that appears in the material plane as a black hole.
He went on to explain that the role of the central black hole is top serve as a converter of matter. It takes in matter and it creates matter. And he said, scientists have already seen evidence of this in the emissions of waves and chains of particles from black holes, by they have failed to recognize it for what it is.
It is the special characteristics of the black hole that the size, weight and balance of the planet is maintained.
One can image a gigantic choreography where cosmic dust and matter, which is the result of waves and chains of particles spewed out by the black hole, is accumulating on the surface of the Earth while erosion and the absorption of material being sucked into the black hole is perfectly balanced.
