宇宙学原理与相对论--I

Cosmological Principle and Relativity - Part I

A. Gouveia Oliveira, Rodrigo de Abreu

摘要:

宇宙学空间膨胀在太阳系尺度上没有确定的结果,通常解释为空间膨胀不影响物质分布的局部各向异性。这也可以解释为考虑与相对性原理兼容的时间依赖性场景,因此支持与观察者的时间位置无关的物理定律。一种考虑这种相对主义情景的理论,即,它将相对性原理推广到位置,体现了宇宙学原理,具有直接拟合局域数据和宇宙数据的内在能力。在第一部分中,它提出了这样一个理论,称为局部相对论(LR)的一般框架,并分析了时空结构。狭义相对论时空被获得,与爱因斯坦的分析没有形式上的冲突,但完全解决了明显的悖论和概念上的困难,包括连续性概念和长期讨论的Sagnac效应。在第二部分中,LR被应用于位置分析。它被证实与太阳系测量和经典的宇宙测试一致,没有暗物质或暗能量。在第二部分中获得的两个新的功能是一个行星的轨道演变的可能性与零确定G变化,支持地球(和火星)过去的气候变暖的情况下,在地球自转加速组件的可能性,兼容与最近的测量。

英文摘要:

The absence of an identified consequence at solar system scale of the cosmological space expansion is usually explained considering that space expansion does not affect local anysotropies in matter distribution. This can also be explained considering a time dependent scenario compatible with Relativity Principle, therefore supporting physical laws independent of the time position of the observer. A theory considering such relativist scenario, i.e., generalizing Relativity Principle to position, embodies Cosmological Principle and can be intrinsically able to fit directly both local and cosmic data. In part I it is presented the general framework of such a theory, called Local Relativity (LR), and analysed the space-time structure. Special Relativity space-time is obtained, with no formal conflict with Einstein analysis, but fully solving apparent paradoxes and conceptual difficulties, including the simultaneity concept and the long discussed Sagnac effect. In part II, LR is applied to positional analysis. It is verified the accordance with solar system measurements and with classic cosmic tests, without dark matter or dark energy. Two of the new features obtained in part II are the possibility of a planetary orbital evolution compatible with a null determination for G variation, supporting a warmer scenario for earth (and Mars) past climate, and the possibility of an accelerating component in earth rotation, compatible with the most recent measurements.
