论文摘要
这项工作基于以幻影能量为主的宇宙的宇宙学场景，其状态参数方程$ w <-1 $及其在远处的渐近行为的分析。作者讨论了将来是否会达到巨大的奇异性。在一般相对论的背景下，即使没有发生其他产生颗粒的贡献，也可以避免由于引力施温格配对的产生而避免大的裂纹奇异性。在该模型中，宇宙以恒定但较大的哈勃速率和能量密度以及恒定但低的地平线熵的状态描述了宇宙。宇宙开头也存在类似的条件。因此，根据这一分析，不仅可以在遥远的未来中避免重大奇异性，而且可以渐近地导致宇宙进入新的通货膨胀阶段，然后可以创建越来越多的宇宙。
This work is based on a cosmological scenario of a universe dominated by phantom energy with equation of state parameter $w<-1$ and the analysis of its asymptotic behaviour in the far-future. The author discusses whether a Big Rip singularity could be reached in the future. Working in the context of general relativity, it is argued that the Big Rip singularity could be avoided due to the gravitational Schwinger pair-production, even if no other particle-creating contribution takes place. In this model, the universe is described in its far-future by a state of a constant but large Hubble rate and energy density, as well as of a constant but low horizon entropy. Similar conditions existed at the beginning of the universe. Therefore, according to this analysis, not only the Big Rip singularity could be avoided in the far-future but also the universe could asymptotically be led to a new inflationary phase, after which more and more universes could be created.
