General Relativity; Quantum Gravity; String Theory and M-Theory. 广义相对论;量子引力(QGR);弦论和M-理论。
Loop quantum gravity occupies a very important place in the development of physics. 环圈量子重力在物理的发展中占有一个非常重要的位置。
A new model such as the causal evolution model of spin networks is needed to describe a dynamics process of loop quantum gravity. 还将这种方法与缠结理论做了比较;要描述圈量子引力(QGR)的动力学过程,需要新的模型,自旋接网圈的因果演化模型就是其中的一种。
Loop quantum gravity is, in the jargon, background independent. 环圈量子重力学用行话来说,是背景独立的。
But complex calculations by Ashtekar's team show that singularities are not allowed by quantum gravity. 但阿贝·阿西提卡团队的进一步计算表明量子引力(QGR)不允许奇点的存在。
