Gravity Theory at the Experimental Interface (Physics)

Nordtvedt教授将完成一个 后牛顿二阶分析的理论框架 引力实验和观测。 该框架将 一个成功的参数化后的自然延伸， 牛顿（PPN）度规场框架的主要发展 调查员和其他人，并导致了完整的经验 第一个后牛顿阶重力的映射，并将 进一步发展那些太阳系观测， 已经开始需要第二个后牛顿秩序框架 他们的充分说明。

Professor Nordtvedt will complete development of a theoretical framework for analysis of second post-Newtonian order gravitation experiments and observations. This framework will be a natural extension of the successful parameterized post- Newtonian (PPN) metric field framework developed by the principal investigator and others, and which led to the complete empirical mapping of the first post-Newtonian order gravity, and will develop further those solar system observations which have already begun to require a second post-Newtonian order framework for their full elucidation.
