解开暗物质-暗能量范式
Unravelling the Dark Matter - Dark Energy Paradigm
摘要：
标准的LambdaCDM宇宙学模型通常被理解为要求Friedmann-Lemaitre-Robertson-Walker（FLRW）度规满足时空度规的广义相对论动力学。FLRW数据为基础的主导参数值，Omega_Lambda=0.73和Omega_m=0.27的暗能量和暗物质+物质，分别通过拟合超新星红移数据。然而，在无压力平坦空间的情况下，LambdaCDM模型最容易从牛顿引力导出，并且是基于太阳系中行星运动的特殊情况。毫不奇怪，当扩展到星系旋转和宇宙学时，牛顿动力学被发现是不需要的，并且修复涉及引入暗物质和暗能量，如本文所示。然而，不同的引力理论导致了对星系旋转和宇宙学的不同解释，并且不需要暗物质或暗能量来拟合超新星数据。它表明，拟合的LambdaCDM模型，这个新的模型，因此独立于实际的超新星数据，需要的LambdaCDM模型参数是上面给出的。因此，我们得出结论，暗能量和暗物质只不过是修正牛顿引力局限性的数学伪像。各种其他数据也简要审查，以说明其他成功的测试，这一新理论的重力。
英文摘要：
The standard LambdaCDM model of cosmology is usually understood to arise from demanding that the Friedmann-Lemaitre-Robertson-Walker (FLRW) metric satisfy the General Relativity dynamics for spacetime metrics. The FLRW data-based dominant parameter values, Omega_Lambda=0.73 and Omega_m=0.27 for the dark energy and dark matter+matter, respectively, are then determined by fitting the supernova red-shift data. However in the pressure-less flat-space case the LambdaCDM model is most easily derived from Newtonian gravity, and which was based on the special case of planetary motion in the solar system. Not surprisingly when extended to galactic rotations and cosmology Newtonian dynamics is found to be wanting, and the fix-up involves introducing dark matter and dark energy, as shown herein. However a different theory of gravity leads to a different account of galactic rotations and cosmology, and does not require dark matter nor dark energy to fit the supernova data. It is shown that fitting the LambdaCDM model to this new model, and so independently of the actual supernova data, requires the LambdaCDM model parameters to be those given above. Hence we conclude that dark energy and dark matter are no more than mathematical artifacts to fix-up limitations of Newtonian gravity. Various other data are also briefly reviewed to illustrate other successful tests of this new theory of gravity.
