无需能量条件的广义相对论中的正质量

Positive Mass in General Relativity Without Energy Conditions

Níckolas de Aguiar Alves, Andre G. S. Landulfo, Bruno Arderucio Costa

AI总结:

针对为何观测质量总是正的问题,本文无需量子理论或能量条件,通过分析多种负质量恒星模型证明其动态不稳定,且任何正压负质量恒星必动态不稳定,为经典广义相对论排斥负质量提供证据。

摘要:

物理学中一个长期存在的问题是为何观测到的质量总是正的。尽管量子场论中的能量条件能部分解答该问题,但本文发现经典广义相对论无需量子理论或能量条件也排斥负质量的证据。方法是考虑多种负质量“恒星”模型并证明它们动态不稳定,进而更严格地证明任何正压负质量恒星必然动态不稳定。

英文摘要:

A long-standing problem in physics is why observed masses are always positive. While energy conditions in quantum field theory can partly answer this problem, in this paper we find evidence that classical general relativity abhors negative masses, without the need for quantum theory or energy conditions. This is done by considering many different models of negative-mass "stars" and showing they are dynamically unstable. A fortiori, we show that any barotropic negative-mass star must be dynamically unstable.
