The hybrid was of two different kinds of orbitals combined to produce the characteristics of a carbonatom. In the early 1990s, the discovery of new carbonatom formations in the mathematical shapes of geodesic spheres sent excited ripples through the scientific community. The incident atom gradually loses kinetic energy by repulsion of the carbonatom as it penetrates several graphene layers. The kinetic energy converted from potential energy is diffused into the entire atoms in the graphene through the overhanging carbonatom. In other words, earth, air, fire and water—indeed, all the substances upon which our life is based—enter into this question of the chemistry of the carbonatom.
