Inflationary expansion

原声例句
时间简史（原版）

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。

时间简史（原版）

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。

宇宙暴胀 Inflation (cosmology)

BICEP2射电望远镜有可能发现了大爆炸后早期宇宙所产生的重力波的证据。[1][2][3][4]
宇宙的历史。根据推测，大爆炸刚发生后的超光速暴胀过程产生了重力波。[1][2][3]
宇宙的历史。根据推测，大爆炸刚发生后的超光速暴涨过程产生了引力波。[1][2][3]

在物理宇宙学中，宇宙暴胀，简称暴胀，是早期宇宙的一种空间膨胀呈加速度状态的过程。 暴胀时期在大爆炸后10秒开始，持续到大爆炸后10至10秒之间。暴胀之后，宇宙继续膨胀，但速度则低得多。

「暴胀」一词可以指有关暴胀的假说、暴胀理论或者暴胀时期。这一假说以及「暴胀」一词，最早于1980年由美国物理学家阿兰·古斯提出。

在微观暴胀时期的量子涨落，经过暴胀放大至宇宙级大小，成为宇宙结构成长的种子，这解释了宇宙宏观结构的形成。很多宇宙学者认为，暴胀解释了一些尚未有合理答案的难题：为什么宇宙在各个方向都显得相同，即各向同性，为甚么宇宙微波背景辐射会那么均匀分布，为甚么宇宙空间是那么平坦，为甚么观测不到任何磁单极子？

Inflation (cosmology) 宇宙暴胀

（重定向自Inflationary expansion）
Full-sky image derived from nine years' WMAP data
History of the Universe - gravitational waves are hypothesized to arise from cosmic inflation, a faster-than-light expansion just after the Big Bang (17 March 2014).[9][10][11]
The physical size of the Hubble radius (solid line) as a function of the linear expansion (scale factor) of the universe. During cosmological inflation, the Hubble radius is constant. The physical wavelength of a perturbation mode (dashed line) is also shown. The plot illustrates how the perturbation mode grows larger than the horizon during cosmological inflation before coming back inside the horizon, which grows rapidly during radiation domination. If cosmological inflation had never happened, and radiation domination continued back until a gravitational singularity, then the mode would never have been inside the horizon in the very early universe, and no causal mechanism could have ensured that the universe was homogeneous on the scale of the perturbation mode.

In physical cosmology, cosmic inflation, cosmological inflation, or just inflation is a theory of exponential expansion of space in the early universe. The inflationary epoch lasted from 10 seconds after the Big Bang to sometime between 10 and 10 seconds. Following the inflationary period, the Universe continues to expand, but at a less rapid rate.
