中文简介: | 膨胀宇宙学对宇宙的许多观测特征给出了一个似是而非的解释,包括它的均匀性、质量密度以及在宇宙微波背景下观察到的波纹的模式。除了我们所能观察到的以外,大多数版本的通货膨胀暗示着我们的宇宙不是独一无二的,而是一个可能无限的多元宇宙的一部分。演讲者描述了通货膨胀的工作原理,通货膨胀的证据,以及为什么他认为应该认真对待多元宇宙的可能性。 |
课程简介: | Inflationary cosmology gives a plausible explanation for many observed features of the universe, including its uniformity, its mass density, and the patterns of the ripples that are observed in the cosmic microwave background. Beyond what we can observe, most versions of inflation imply that our universe is not unique, but is part of a possibly infinite multiverse. The speaker describes the workings of inflation, the evidence for inflation, and why he believes that the possibility of a multiverse should be taken seriously. |
