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.
膨胀扩张期结束之后，宇宙会出现这样的情况，那就是一些地方的扩大要稍快于另一些地方。
After the period of inflationary expansion was over, one would be left with a universe that was expanding slightly faster in some places, than in others.
