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.

一项新的研究计划将在 宇宙学中强引力系统的动力学演化， 天体物理学 这将涉及研究的影响， 恒星引力终点附近的量子物质 包括反作用效应在内的球面坍缩 对称时空 早期的量子行为 宇宙也将通过研究边界来研究 在另一种方法中的波函数的条件。 的 宇宙将由一个密度矩阵描述， 一些局部的知识，以同样的方式，作为任何其他 普通量子系统 本研究的目的是：1）探索 目前已知的物理定律的局限性，以及2） 发现需要进行可能的修改以扩展它们 超出了他们已知的有效范围。
