邪恶轴心中的善良
Goodness in the Axis of Evil
摘要：
观测到2-4-8-16宇宙微波背景球谐方向与一个令人惊讶的大WMAP温度最低值方向、一个大射电星系空洞以及一个意想不到的星系自旋方向和旋向性的一致性。这条直线指向RA=202度，Delta = 25度，被称为“邪恶之轴”。已经有许多作者评论了AE如何影响我们在Lamda-CDM、暖暗物质、弦论和流体引力动力学（HGD）框架内对宇宙结构如何出现的理解。后者唯一预测的大小尺度的空隙和物质凝聚，根据估计的流体力在早期阶段的结构形成。从简单的高斯性质的WMAP数据的偏离有利于两个制度的湍流结构的形成，并从这些我们作出预测的性质更精细的结构预计将与普朗克航天器测量。从HGD，摩擦限制了超星系团的膨胀到30 Mpc，但超空洞已经随着宇宙膨胀到300 Mpc。
英文摘要：
An unexpected alignment of 2-4-8-16 cosmic microwave background spherical harmonic directions with the direction of a surprisingly large WMAP temperature minimum, a large radio galaxy void, and an unexpected alignment and handedness of galaxy spins have been observed. The alignments point to RA=202 degrees, delta = 25 degrees and are termed the ``Axis of Evil''. Already many authors have commented about how the AE impacts our understanding of how structure emerged in the Universe within the framework of Lamda-CDM, warm dark matter, string theory, and hydro-gravitational dynamics (HGD). The latter uniquely predicts the size scales of the voids and matter condensations, based upon estimates of fluid forces in the early phases of structure formation. Reported departures from simple Gaussian properties of the WMAP data favor two regimes of turbulent structure formation, and from these we make predictions of the nature of finer structure expected to be measured with the PLANCK spacecraft. From HGD, friction has limited the expansion of superclusters to 30 Mpc but supervoids have expanded with the universe to 300 Mpc.
