尽管宇宙加速膨胀对天文学家来说很惊讶，但是这个发现为主流宇宙学模型提供了一个基本要素。
Although the accelerating cosmic expansion came as a surprise to astronomers, its discovery provided an essential ingredient in what has become the prevailing cosmological model.
根据标准的宇宙学模型，宇宙最有可能的结局是永远膨胀下去。
According to standard cosmology models the most likely outcome for the universe is that it will expand forever.
永久膨胀是由量子宇宙学模型得出的结论，在这个模型中，膨胀的气泡可以随意出现和消失。
Eternal inflation is a quantum cosmological model where inflationary bubbles can appear out of nothing.
我的一个学生雷蒙·拉夫勒蒙进一步发现，在一个稍复杂的模型中，宇宙的坍缩和膨胀非常不同。
Further, one of my students, Raymond Laflamme, found that in a slightly more complicated model, the collapse of the universe was very different from the expansion.
我还被我作过的一项简单的宇宙模型的研究所误导，在此模型中坍缩相似乎是膨胀相的时间反演。
I was also misled by work I had done on a simple model of the universe in which the collapsing phase looked like the time reverse of the expanding phase.
