Theoretical Research in General Relativity and Relativistic Cosmology (Physics)

一个新的研究项目将在宇宙学和天体物理学强引力系统的动态演化中启动。这将涉及研究恒星引力坍缩终点附近的量子物质的效应，包括球对称时空中的反作用效应。早期宇宙的量子行为也将通过另一种方法研究其波函数的边界条件来研究。宇宙将用一个与某些部分知识相一致的密度矩阵来描述，就像任何其他普通量子系统一样。这项研究的目标是：1)探索目前已知的物理定律的局限性，2)发现可能的修改需要将它们扩展到已知的有效性范围之外。

A new program of research will be initiated in the dynamical evolution of strong gravity systems in cosmology and astrophysics. This will involve the study of effects of quantum matter near the end point of a stellar gravitational collapse including backreaction effects in spherically symmetric spacetimes. The quantum behavior of the early universe will also be investigated by study of the boundary condition of its wave function in an alternate approach. The universe will be described by a density matrix consistent with some partial knowledge, in the same manner as any other ordinary quantum systems. The goal of this research is to: 1) explore the limitations to the presently known laws of physics, and 2) uncover the need for possible modification to extend them outside of their known range of validity.
