论文摘要
我们认为将旋转和扭转成黑洞的流体的球形对称球的重力崩溃。我们使用具有相对论自旋流体的Tolman Metric和Einstein-Cartan场方程作为来源。我们表明，扭转的重力排斥可以防止奇异性，并用非弹跳替换。收缩期间的量子颗粒产生有助于扭转剪切占主导地位。扩展过程中的颗粒产生可以产生有限的通货膨胀期，并产生大量物质。事件范围另一侧的最终封闭宇宙可能有几次弹跳。这样的宇宙是振荡的，每个周期的大小都比上一个周期大，直到达到宇宙学的大小并无限期扩展为止。因此，我们的宇宙可能起源于黑洞。
We consider gravitational collapse of a spherically symmetric sphere of a fluid with spin and torsion into a black hole. We use the Tolman metric and the Einstein--Cartan field equations with a relativistic spin fluid as a source. We show that gravitational repulsion of torsion prevents a singularity and replaces it with a nonsingular bounce. Quantum particle production during contraction helps torsion to dominate over shear. Particle production during expansion can generate a finite period of inflation and produce enormous amounts of matter. The resulting closed universe on the other side of the event horizon may have several bounces. Such a universe is oscillatory, with each cycle larger in size then the previous cycle, until it reaches the cosmological size and expands indefinitely. Our universe might have therefore originated from a black hole.
