We consider a model in which the Universe is the direct product of an ordinary (3+1)-dimensional space--a brane where all the standard model fields are confined-and a compact hyperbolic manifold. The decay of massive Kaluza-Klein modes leads to the injection of bulk entropy into the observable Universe. The large statistical averaging inherent in the collapse of the initial entropy onto the brane smoothes out any initial inhomogeneities in the distribution of matter and of three-curvature.
我们考虑这样一个模型,其中宇宙是一个普通的(3 + 1)维空间(一个所有标准模型场都被限制在其上的膜)与一个紧致双曲流形的直积。大质量卡鲁扎 - 克莱因模式的衰变导致体熵注入可观测宇宙。初始熵在膜上坍缩过程中固有的大统计平均消除了物质分布和三维曲率中任何初始的不均匀性。
