摘要: A united approach of the large-scale structure of a closed universe and the local spherically symmetric gravitational field is given by supposing an appropriate boundary condition. The general feature of the model obtained are the following.The universe is approximately homogeneous and isotropic on the average on large scale and is expanding at present, as described by the standard model; while locally,the small exterior region of a star started long ago to contract, as expected by the gravitational collapse theory.
