均匀密度零压星的完整的引力解
Complete gravitational solution of a star with uniform density and zero pressure
【摘要】 证明了Oppenheimer和Snyder关于均匀密度零压星的引力塌缩的经典解是不完整的 ,它并不能正确地连接作为内解和外解的Friedmann度规和Schwarzschild度规 ;通过在离散时空上拓展解参数而构成了一个完整的引力解 ,它实现了Friedmann度规和Schwarzschild度规之间的等价连接 ,并可以证明是奇性自由的 ;这个完整的引力解显示了物质 ,引力和离散时空结构之间的关联性
【Abstract】 The collapse solution of a star with uniform density and zero pressure given in the classic paper of Oppenheimer and Snyder is proved to be incomplete;it cannot correctly connect the Friedmann and Schwarzschild metrics as the interior and exterior solu tions. By the extension of solution parameter in the discrete spacetime,we construct a complete gravitational solution,which could make an equivalence connection between the Friedmann and Schwarzschild metrics and is proves to be singularity\|free.The solution shows that there exists a relationship among matter,gravitation and discrete spacetime configuration.
【Key words】 uniform density and zero pressure star; Friedmann metric; Schwarzschild metric; discrete spacetime;
