标题： Inhomogeneous Big Bang Cosmology

摘要： 在本信中，我们概述了大爆炸宇宙学的非均匀模型。 对于这里使用的非均匀时空，宇宙起源于无限遥远的过去，当时被真空能量主导，并在无限遥远的未来结束为由“炽热且相对论性”的物质组成的宇宙。 在所考虑的非均匀时空中，物质的空间分布为{\em 任意的}。 因此，在此宇宙学中可以从适当的“初始”密度对比度中产生观测到的结构。 标准的大爆炸宇宙学模型的不同问题也在当前的非均匀模型中得到了解决。 这个大爆炸宇宙学的非均匀模型预测宇宙将以“炽热的终结”告终。 显示英文摘要

摘要： In this letter, we outline an inhomogeneous model of the Big Bang cosmology. For the inhomogeneous spacetime used here, the universe originates in the infinite past as the one dominated by vacuum energy and ends in the infinite future as the one consisting of "hot and relativistic" matter. The spatial distribution of matter in the considered inhomogeneous spacetime is {\em arbitrary}. Hence, observed structures can arise in this cosmology from suitable "initial" density contrast. Different problems of the standard model of Big Bang cosmology are also resolved in the present inhomogeneous model. This inhomogeneous model of the Big Bang Cosmology predicts "hot death" for the universe.
