静态宇宙的回归和宇宙学的终结

The Return of a Static Universe and the End of Cosmology

Lawrence M. Krauss, Robert J. Scherrer

摘要:

我们证明,当我们把当前的$Λ$ CDM宇宙在时间上向前推时,哈勃膨胀的所有证据都将消失,因此我们的“岛屿宇宙”中的观测者将从根本上无法确定宇宙的真实性质,包括高度主导的真空能量的存在,CMB的存在,以及轻元素的原始起源。随着现代大爆炸的这些支柱消失,这个时代将标志着宇宙学的终结和静态宇宙的回归。从这个意义上说,适合未来观测者的坐标系也许会与德西特宇宙首次提出时的静态坐标系非常相似。

英文摘要:

We demonstrate that as we extrapolate the current $Λ$CDM universe forward in time, all evidence of the Hubble expansion will disappear, so that observers in our "island universe" will be fundamentally incapable of determining the true nature of the universe, including the existence of the highly dominant vacuum energy, the existence of the CMB, and the primordial origin of light elements. With these pillars of the modern Big Bang gone, this epoch will mark the end of cosmology and the return of a static universe. In this sense, the coordinate system appropriate for future observers will perhaps fittingly resemble the static coordinate system in which the de Sitter universe was first presented.
