从广义相对论的弱修正看球对称的静止宇宙

A spherically symmetric and stationary universe from a weak modification of general relativity

Christian Corda, Herman J. Mosquera Cuesta

摘要:

它表明,广义相对论的一个弱的修改,在线性化的方法,呈现出一个球对称的宇宙模型和固定。这是由于在线性化重力中存在第三种偏振模式,其中存在“曲率”能量项。这样的能量原则上可以被称为暗能量。该模型也有助于更好地理解Einstein-Vlasov系统的框架。

英文摘要:

It is shown that a weak modification of general relativity, in the linearized approach, renders a spherically symmetric and stationary model of the universe. This is due to the presence of a third mode of polarization in the linearized gravity in which a "curvature" energy term is present. Such an energy can, in principle, be identified as the Dark Energy. The model can also help to a better understanding of the framework of the Einstein-Vlasov system.
