暗物质的效应能用时空的湍流来解释吗？
Can Effects of Dark Matter be Explained by the Turbulent Flow of Spacetime?
摘要：
在过去的四十年里，对暗物质的研究一直是天体物理学的主要焦点之一，尽管还没有任何直接证据证明它的存在（Porter et al. 2011）。暗物质存在的间接证据主要来源于恒星在其宿主星系中的旋转速度，在那里，恒星的轨道速度与它们到星系中心的距离无关，而不是具有~r^1/2的径向依赖性，这导致了暗物质的存在（Porter et al. 2011; Peebles 1993）。我们提出了另一种解释星系内观察到的恒星运动，结合标准的处理流体状时空的可能性，通过宇宙的“大规模流动”的质量。时空的微分"流"可以产生能够提供超过牛顿力学预测的"感知"旋转速度的涡旋。虽然我们的理论更详细的分析即将到来，我们发现一个粗略的“数量级”计算可以解释这一现象。我们还发现，这可以用来解释在"子弹团"等球状星团周围观测到的引力透镜现象。
英文摘要：
For the past forty years the search for dark matter has been one of the primary foci of astrophysics, although there has yet to be any direct evidence for its existence (Porter et al. 2011). Indirect evidence for the existence of dark matter is largely rooted in the rotational speeds of stars within their host galaxies, where, instead of having a ~ r^1/2 radial dependence, stars appear to have orbital speeds independent of their distance from the galactic center, which led to proposed existence of dark matter (Porter et al. 2011; Peebles 1993). We propose an alternate explanation for the observed stellar motions within galaxies, combining the standard treatment of a fluid-like spacetime with the possibility of a "bulk flow" of mass through the Universe. The differential "flow" of spacetime could generate vorticies capable of providing the "perceived" rotational speeds in excess of those predicted by Newtonian mechanics. Although a more detailed analysis of our theory is forthcoming, we find a crude "order of magnitude" calculation can explain this phenomena. We also find that this can be used to explain the graviational lensing observed around globular clusters like "Bullet Cluster".
