de Sitter和反de Sitter时空的定态类似物:支持$Λ$是暗流体的证据

Stationary analogs of de Sitter and anti-de Sitter spacetimes: Evidence in favor of $Λ$ as a dark fluid

M. Nouri-Zonoz, A. Nouri-Zonoz

摘要:

我们引入新的爱因斯坦空间,这是{ \it静态模拟的德西特和ani-de西特}时空。有$Λ$作为他们的唯一参数,在这些解决方案的固有各向异性似乎是一个困境,如果我们把宇宙项作为一个恒定的背景曲率。由于宇宙学项是当前宇宙学模型中不可分割的元素,这些模型的进一步发展以及与此项相关的问题的解决,包括任何量子方面,将关键取决于此项的真实性质。据我们所知,这些解是首次出现在文献中,不仅为宇宙项的研究开辟了一个新的方向,而且为宇宙项是暗流体提供了强有力的证据,从而解决了上述难题。

英文摘要:

We introduce novel Einstein spaces which are the {\it stationary analogs of de Sitter and ani-de Sitter} spacetimes. Having $Λ$ as their only parameter, the inherent anisotropy in these solutions appears as a dilemma if we treat the cosmological term as a constant background curvature. Since the cosmological term is an inseparable element of the current cosmological models, further development of these models as well as resolution of the problems related to this term, including any quantum aspect will crucially depend on the true nature of this term. These solutions, which to the best of our knowledge appear here for the first time in the literature, not only open a new direction to study the cosmological term, but also provide strong evidence in favor of the cosmological term as a dark fluid, hence furnishing a resolution to the above mentioned dilemma.
