摘要

全息时空是一种量子引力理论,它概括了弦理论和量子场论,在其暴胀模型中预测了早期物质主导时代的黑洞。在这些黑洞衰变之前,有可能会有足够多的这些粒子合并,从而产生今天在宇宙微波背景中可见的辐射。为了发现是否存在这种情况,我们进行了一次简单的计算机模拟。我们的研究表明,在全息时空膨胀模型中,合并不会形成有问题的黑洞。然而,我们得出结论,在该理论中无条件地形成了包含黑洞残余的微小束缚结构。由于黑洞衰变产物大多是大质量标准模型粒子,也许还有它们的超级伙伴,这些结构的命运是一个复杂的动力学问题,需要进一步研究。它表明,在辐射主导时代开始时,原始结构的大小可能与地平线大小相当。这在当前模型中大约为 10^9 L_P$。

Black hole mergers in holographic space time models of cosmology
Holographic space-time, a theory of quantum gravity that generalizes string theory and quantum field theory, predicts black holes in the early matter-dominated era of its models of inflation. Before these black holes can decay, there is a chance that enough of these particles merge to produce radiation visible today in the Cosmic Microwave background. To discover if this is the case, we perform a rudimentary computer simulation. We show that no problematic black holes are formed by mergers in the Holographic Space-time models of inflation. However, we conclude that tiny bound structures containing black holes remnants form in this theory unconditionally. Since black hole decay products are mostly massive standard model particles, and perhaps their superpartners, the fate of these structures is a complicated dynamical problem that requires further study. It suggests the possibility of primordial structures on the order of the horizon size at the beginning of the radiation dominated era. This is about $10^9 L_P$ in the current model.
