暗能量的欠定性

Underdetermination of dark energy

William J. Wolf, Pedro G. Ferreira

AI总结:

本文论证了即使宇宙学巡天精度不断提高,也无法精确确定暗能量的微观物理模型,最多只能获得唯象描述,且现有唯象方案不足以揭示其基本理论。

摘要:

有令人信服的证据表明,宇宙正在经历一个晚期的加速膨胀阶段。对这一行为最简单的解释之一是暗能量的存在。人们已经提出了大量关于暗能量的微观物理模型。希望随着宇宙学巡天精度的不断提高,能够精确地确定模型。我们表明这不太可能,并且我们最多只能对暗能量的微观物理有一个唯象描述。此外,我们认为当前的唯象方案不足以阐明暗能量的基本理论。

英文摘要:

There is compelling evidence that the Universe is undergoing a late phase of accelerated expansion. One of the simplest explanations for this behaviour is the presence of dark energy. A plethora of microphysical models for dark energy have been proposed. The hope is that, with the ever increasing precision of cosmological surveys, it will be possible to precisely pin down the model. We show that this is unlikely and that, at best, we will have a phenomenological description for the microphysics of dark energy. Furthermore, we argue that the current phenomenological prescriptions are ill-equipped for shedding light on the fundamental theory of dark energy.
