【摘要】 依据圈量子引力,计算出空时跃迁体积膨胀和度量起伏的结果,同时给出了引力场的一种生成途径.利用量子群SU 2 q表示的有限性,提出了一种不存在空时奇点的量子动态宇宙模型,并将其与大爆炸宇宙模型做了某些比较.更多还原

【Abstract】 According to the loop quantum gravity,calculates and obtains the results of the volume inflation and the metric fluctuation,and a creation way of gravity field is given,during the transition of the spacetime.Using finiteness of the representation of quantum group,a quantum dynamic cosmdogy model without singularity of spacetime is raised,and it is compared with the big bang cosmology model.更多还原
