In this contribution, we identify two scenarios for the evolutionary branch cut universe. In the first scenario, the universe evolves continuously from the negative complex cosmological time sector, prior to a primordial singularity, to the positive one, circumventing continuously a branch cut, and no primordial singularity occurs in the imaginary sector, only branch points. In the second scenario, the branch cut and branch point disappear after the realization of the imaginary component of the complex time by means of a Wick rotation, which is replaced by the thermal time. In the second scenario, the universe has its origin in the Big Bang, but the model contemplates simultaneously a mirrored parallel evolutionary universe going backwards in the cosmological thermal time negative sector. A quantum formulation based on the Wheeler–DeWitt equation is sketched and preliminary conclusions are drawn.

超越大爆炸奇点的时间极限:分支切割宇宙的情景

在这个贡献中,我们确定了进化分支切割宇宙的两种场景。在第一种情况下,宇宙从原始奇点之前的负复宇宙时间扇区不断演化到正宇宙时间扇区,不断绕过分支切割,在虚扇区中没有原始奇点,只有分支点。第二种场景,实现后分支切割和分支点消失通过 Wick 旋转来计算复数时间的虚部,由热时间代替。在第二种情况下,宇宙起源于大爆炸,但该模型同时考虑了一个镜像平行进化宇宙,它在宇宙热时间负扇区中倒退。勾勒出基于惠勒-德威特方程的量子公式,并得出初步结论。
