暗能量可能是引力的一种表现形式吗？
Could Dark Energy be a Manifestation of Gravity?
摘要：
它表明，所谓的暗能量可能是一种表现的引力涡旋产生的“重力磁”（GM）力场：与宇宙物质旋转和惯性时空框架拖动。广义相对论性的哥德尔-奥布霍夫时空度规结合了宇宙的膨胀和旋转，用来评估这种力。这个度量在这里用球面共动坐标表示。通过一个宇宙时间演化，它表明，当径向排斥GM力的大小超过熟悉的或通常的吸引引力“引力电”（GE）力时，宇宙加速是预期的：与宇宙物质和时空翘曲（或曲率）有关。一般来说，这种宇宙加速膨胀的现象似乎在宇宙历史上发生过两次：暴胀阶段和现在的加速阶段。在这个模型中，这两个阶段可能相关，也可能不相关。这里提出的宇宙学模型是在爱因斯坦的广义相对论的黎曼-嘉当时空（“广义”爱因斯坦-嘉当引力理论）的背景下描述的，其中包括宇宙旋转，时空扭曲的影响，它被认为是引力的内在部分。此外，还导出了宇宙原始磁场的解析表达式。这个磁场在宇宙时间内的演化表明它与理论和观测结果一致。此外，宇宙物质的自旋密度似乎将这个磁场耦合到GM场，也将这个磁场耦合到GE场。
英文摘要：
It is shown that so-called dark energy could possible be a manifestation of the gravitational vortex producing the "gravitomagnetic" (GM) force field: associated with cosmic matter rotation and inertial spacetime frame dragging. The general relativistic Godel-Obukhov spacetime metric which incorporates expansion and rotation of the Universe is used to evaluate this force. This metric is expressed here in spherical comoving coordinates. Through a cosmic time evolution, it is shown that cosmic acceleration is expected when the magnitude of the radial repulsive GM force exceeds that of the familiar or usual attractive gravitational "gravitoelectric" (GE) force: associated with just cosmic matter and spacetime warping (or curvature). In general, this phenomenon of cosmic accelerated expansion appears to have occurred twice in the history of the Universe: the inflationary phase and the present-day acceleration phase. It is suggested in this model that the two phases may or may not be related. The cosmological model presented here is described in the context of Einstein's Theory of General Relativity in Riemann-Cartan spacetime (the "generalized" Einstein- Cartan theory of gravity), which includes cosmic rotation, its effect of spacetime torsion, and it being considered as an intrinsic part of gravity. Also, an associated derived analytical expression for the cosmic primordial magnetic field is presented. Evolving this magnetic field over cosmic time shows it to be consistent with theory and observations. In addition, it appears that the spin density of cosmic matter couples this magnetic field to the GM field, and also couples this magnetic field to the GE field.
