The universe would have started off with a period of exponential or " inflationary" expansion in which it would have increased its size by a very large factor.

宇宙会从一个指数或“暴胀”膨胀期开始，在这个时期它的大小会增加一个非常大的因子。

As they expanded, the energy of the field in them would slowly decrease until the inflationary expansion changed to an expansion like that in the hot big bang model.

随着它们膨胀，它们中的场能量会慢慢降低，直到膨胀膨胀变成热大爆炸模型中的膨胀。
