Abstract

It goes without saying that we are stuck with the Universe we have. Nevertheless, we would like to go beyond simply describing our observed Universe, and try to understand why it is that way rather than some other way. When considering both the state in which we find our current Universe, and the laws of physics it obeys, we discover features that seem remarkably unnatural to us. Physicists and cosmologists have been exploring increasingly ambitious ideas in an attempt to explain how surprising aspects of our Universe can arise from simple dynamical principles.

摘要

不言而喻，我们只能面对现有的宇宙。然而，我们希望不仅仅是描述我们所观测到的宇宙，而是试图理解它为何是这样而不是其他样子。当我们考虑当前宇宙的状态以及它所遵循的物理定律时，会发现一些对我们来说显得非常不自然的特征。物理学家和宇宙学家一直在探索越来越大胆的想法，试图解释我们宇宙中那些令人惊讶的方面是如何从简单的动力学原理中产生的。
