摘要：

我们表明，没有必要的假设暗能量（DE）和暗物质（DM）来解释归因于他们的现象。与过去十年的共识相反，我们证明了宇宙尺度因子的时间导数是一个常数。我们推导出哈勃参数H（z）作为红移z的函数。基于H（z），我们推导出距离模量与log（z）的曲线。这条曲线拟合超新星观测数据，没有任何自由参数。这种拟合与当前宇宙学所获得的拟合一样好，后者需要自由参数Omega_M和Omega_Lambda。利用哈勃球（HS）中的全球引力能量密度等于宇宙微波背景（CMB）能量密度这一迄今未被注意的事实，我们得到了这些结果。我们推导出了支配星系内和星系周围天体运动的动力学和运动学关系。这个推导不需要任何引力物质超过观察到的重子物质。由这些关系得到的理论旋转曲线（RC）与实测RC相吻合。我们通过研究星系周围的局部引力能量密度和宇宙微波背景能量密度之间的相互作用得到这些结果。这种相互作用导致星系周围的空间膨胀不均匀和各向异性。

英文摘要：

We show that there is no need for the hypothetical Dark Energy (DE) and Dark Matter (DM) to explain phenomena attributed to them. In contrast to the consensus of the last decade, we show that the time derivative of the cosmological scale factor, is a constant. We derive H(z), the Hubble parameter, as a function of the redshift, z. Based on H(z), we derive a curve of the Distance Modulus versus log(z). This curve fits data from supernovae observations, without any free parameters. This fit is as good as that obtained by current cosmology, which needs the free parameters Omega_M and Omega_Lambda. We obtain these results by using the hitherto un-noticed fact that the global gravitational energy density in our Hubble Sphere (HS) is equal to the Cosmological Microwave Background (CMB) energy density. We derive the dynamic and kinematic relations that govern the motions of celestial bodies in and around galaxies. This derivation does not require any gravitating matter beyond the observed baryonic matter. The theoretical Rotation Curves (RC), resulting from these relations, fit observed RCs. We obtain these results by examining the interplay between the local gravitational energy density, around a galaxy, and the CMB energy density. This interplay causes the inhomogeneous and anisotropic space expansion around a galaxy.
