释义

Inflationary model

原声例句
时间简史(原版)

The new inflationary model was a good attempt to explain why the universe is the way it is.

新的暴胀模型是一个很好的尝试来解释为什么宇宙是这样的。

时间简史(原版)

After the conference I gave a seminar on the inflationary model and its problems at the Sternberg Astronomical Institute.

会议结束后,我在斯腾伯格天文研究所举办了一场关于暴胀模型及其问题的研讨会。

时间简史(原版)

This work on inflationary models showed that the present state of the universe could have arisen from quite a large number of different initial configurations.

这项关于暴胀模型的工作表明,宇宙的当前状态可能源于大量不同的初始配置。

时间简史(原版)

So even the inflationary model does not tell us why the initial configuration was not such as to produce something very different from what we observe.

因此,即使是暴胀模型也没有告诉我们为什么初始配置不会产生与我们观察到的非常不同的东西。

The inflationary model describes a brief era of incredibly rapid expansion that relates quantum fluctuations in the energy of the early universe; to the formation of clumps of gas that eventually led to galaxies.

膨胀模型描述了一个短暂的宇宙暴涨期,它把宇宙初期能量的量子涨落与团状气体的形成相关联;后者最终形成了星系。

The inflationary model describes a brief era of incredibly rapid expansion that relates quantum fluctuations in the energy of the early universe, to the formation of clumps of gas that eventually led to galaxies.

但,这样的话,银河 和星星又是怎麽生成的?膨胀模型就描述了一个非常快速扩张的简短时代,让早期宇宙能量中的 量子扰动与气体块的形成。

时间简史(原版)

At later real times, the universe would expand like the chaotic inflationary model proposed by Linde (but one would not now have to assume that the universe was created somehow in the right sort of state).

在后来的真实时间,宇宙会像林德提出的混沌暴胀模型一样膨胀(但现在人们不必假设宇宙是以某种正确的状态被创造出来的)。

宇宙暴胀 Inflation (cosmology)

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 model)
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.
