论文摘要
我们在连接表示中研究了量子热爆炸，其中一个运动M的恒定物质定义了时间。 M中的叠加诱导单一内部产品。波功能揭示了没有新物理或补充边界条件的奇异性问题的解决方案。随着时间的流逝，概率峰最终以最大曲率停止，此后的高度下降，而对称收缩峰值上升。大爆炸被签约和扩大常规宇宙的叠加所取代。我们将这些发现与指标表示的情况进行了对比，在指标表示中，单一进化需要奇异性的边界条件。
We study a quantum Hot Big Bang in the connection representation, with a matter constant of motion m whose conjugate defines time. Superpositions in m induce a unitary inner product. The wavefunction reveals a resolution of the singularity problem without new physics or supplementary boundary conditions. Backtracking in time, the probability peak eventually halts at a maximum curvature, its height dropping thereafter while a symmetric contracting peak rises. The Big Bang is replaced by a superposition of contracting and expanding regular Universes. We contrast these findings with the situation in the metric representation, where boundary conditions at the singularity are needed for unitary evolution.
