能动张量密度守恒定律与物质起源问题

The Conservation Law of Energy-Momentum Tensor Density and the Origin of Matter

摘要: 可以证明，若要包括引力现象在内的物理体系在采用两种不同的能动张量密度定义时都能满足能动张量密度守恒定律，则这两种能动张量密度定义之间必须满足一定的关系。这种关系意味着物质可从无到有在时空中各处创生出来，这就给物质的起源问题的研究提供了可能性。本文对此发表了作者的一些看法。

Abstract: 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.
