It could be proved that there must be some definite relationships between two definitions of the energy-momentum tensor density, if the conservation law of the energy-momentum tensor density is all satisfied by these two different definitions of the energy-momentum tensor density for the physical system which includes the gravity phenomenon. These relationships provide the possibility that the matter could be created from nothing throughout the space-time which might explain the origin of the matter. This paper has published some of the views of the author.
