The cosmological physicist from Princeton? Yes.

普林斯顿大学的宇宙物理学家 没错。

They're light because of the effects of cosmological red shift.

他们质量很轻，这是因为宇宙红移的影响。

When light loses energy its wavelength gets longer — that's what cosmological redshift is.

当光失去能量，它的波长会变长，这就是宇宙学的红移。

But America's cosmological dominance could soon be challenged by China, as well as other space ambitious nations.

但美国在宇宙领域的主导地位可能很快就会受到中国以及其他雄心勃勃的国家的挑战。

Finally, there is the cosmological arrow of time.

最后，还有时间的宇宙箭头。

No radio  signal can penetrate this cosmological giant.

没有无线电信号可以穿透这个宇宙巨人。

Stars, planets, and cosmological unions formed.

恒星、行星和宇宙联盟形成。

So it's the creator of the next cosmological era, the Anthropocene.

所以它是下一个宇宙学时代人类世的创造者。

Others counter that slight modifications of the cosmological models would avoid the problem, or that Boltzmann's brains can't actually physically form.

其他人则反驳说，对宇宙学模型稍作修改就可以避免这个问题，或者说玻尔兹曼的大脑实际上不可能在物理上形成。

This idea was elaborated by Ptolemy in the second century A.D. into a complete cosmological model.

这个想法在公元二世纪被托勒密阐述为一个完整的宇宙模型。

We are wired to seek cosmological explanations, to sacralize beliefs that unite us in transcendent purpose.

我们渴望寻求宇宙学的解释，神圣化将我们团结在超越目标中的信念。

And this trend of distant galaxies moving away from us, and from one another, is called cosmological redshift.

这种遥远星系 远离我们、彼此远离的趋势被称为 宇宙学红移。

The energy of the field in those regions would behave like a cosmological constant.

这些区域的场能表现得像一个宇宙常数。

But there's another kind of hawking radiation coming from the cosmological event arising of the early inflationary universe.

但还有另一种霍金辐射来自于早期暴胀宇宙的宇宙学事件。

There once was a man who was referred to his prediction of a cosmological constant as the single " biggest blunder" of his career.

曾有一个人因为他对一个宇宙常数的预测而被称为他事业中的最大错误。

To their surprise, the researchers found that the old black holes had grown ten times faster than cosmological models would predict.

令他们惊讶的是，研究人员发现，老黑洞的增长速度比宇宙学模型预测的速度快十倍。

Dark energy has been mostly thought of as a cosmological constant, which doesn’t look good for the Big Crunch theory’s validity.

暗能量通常被认为是宇宙学常数，这看起来不利于大挤压理论的有效性。

It became clear that gamma-ray bursts actually were...cosmological, coming from very far outside of our galaxy, from millions and billions of light years away.

这变得清楚了，伽玛射线爆实际上是… … 宇宙的，是来自银河系外遥远的地方，来自数百万和数十亿光年以外。

This is the explanation of why we observe that the thermodynamic and cosmological arrows of time point in the same direction.

这就是为什么我们观察到热力学和宇宙学时间箭头指向同一方向的原因。

So after mathematics, my second favorite tool for addressing these large cosmological questions is the biggest laboratory we know, the universe itself.

因此，在数学之后， 我第二喜欢的解决这些大型宇宙学问题的工具是我们所知道的最大的实验室，即宇宙本身。
