摘要
热大爆炸模型因成功解释了许多重要观测事实而为多数宇宙学家所接受,并获得了标准模型的称号。然而自80年代后期以来,它却受到了一系列新观测事实的严重挑战。大爆炸宇宙学家们正在原来的基础上继续发展,以求找到问题的答案。一些本来就不赞成标准模型的宇宙学家则对它提出了全面的批评。 本文旨在对这些不同见解作一简介,它主要涉及对微波背景的认识、非宇宙学红移问题、年轻星系、离散天体的演化以及非标准模型本身的一些情况。
Recently, some cosmologists who disagree with the standard model, which at present is under the challenge from the new facts revealed in the field of observational cosmology in last a few years, gave the Big Bang model a severe criticism and suggested their own model as an 'alternative view'.A brief review on it is presented in this article, in which among the issues discussed are those concerning the cosmic microwave background radiation, noncosmological redshift, evolution of discrete celestial objects, and some points about the alternative hypothesis itself.
