Hawking was also a cosmologist, a mathematician and an author.

霍金也是一位宙学家、数学家和作家。

While a present-day cosmologist might describe the stabilising influence of our Earth's tilt.

而当宙学家可能会描述月球对地球倾斜稳定起了很大作用。

Figuring out what dark energy is, is probably the number one goal of cosmologists today.

搞清楚暗能量是什么可能是宙学家现在排在首位目标。

And that lets cosmologists look back to the very dawn of the universe.

让宙学家回顾了宙黎明时期。

Cosmologists have come up with a name, dark energy.

宙学家给它起了名字，暗能量。

Cosmologists are making sense of startling discoveries.

宙学家正在那些惊发现。

The second way to measure curvature is to measure the thing that causes space to curve in the first place: the density of energy and matter throughout the Universe. Which cosmologists have also measured.

宙中物质和能量密度。宙学家也对此进行了测量。

Most cosmologists agree that the universe began with a gigantic explosion known as the Big Bang, but some believe that this event will inevitably lead to the end of the universe itself, known as the Big Rip.

多数宙学家确信宙起源一场称作宙大爆炸巨大爆炸，但是某些宙学家也相信，宙大爆炸会不可避免地通往宙终结，这被称为大撕裂。

It doesn't have the beauty of a spiral galaxy or a nebula but to a scientist, to a cosmologist, it is the most beautiful picture ever taken, because it contains a vast amount of information about the very earliest history of our universe.

上面没有漂亮螺旋星系，或是星云什么，但对宙科学家来说，这张照片意义非凡，因为它详尽地记载着宙最早期样貌。

The big issue, even for cosmologists today, is whether or not that primordial state contained some of the information needed for the appearance and development of the cosmos.

即使对天宙学家来说，这也是个大问题：原始形态是否包含对宙外观和发展所需一些信息。

To be clear, this concept is important to cosmologists, but it can be weird and confusing to someone who is just learning about all this.

需要说明是，这个概念对宙学家来说很重要，但对刚开始学习这些来说，它可能很奇怪，很令感到困惑。

Supernovae provided the explanation, and it was an English cosmologist almost as singular in manner as Fritz Zwicky who figured it out.

超新星提供了解释。这个解释是一位几乎像弗里茨? 兹威基一样行为古怪英国宙学家作出。

Boltzmann didn't get quite that far in his thinking; the brains themselves were introduced by later cosmologists building on his work.

玻尔兹曼在他想法中并没有到达这一步，大脑本身理论由后续宙学家基他成果得出。

But even without being able to see the universe in those first instants, cosmologists are pretty sure about a few things.

但是即使不能在最初瞬间看到宙，宙学家也相当确定一些事情。

In this context, Boltzmann's paradox has found renewed interest by contemporary cosmologists.

在这种情况下，玻尔兹曼悖论重新引起了当代宙学家兴趣。

And by comparison, the entire universe is very simple and even the cosmologists will admit that.

相比之下，整个宙非常简单，甚至宙学家也会承认这一点。

Cosmologists have done the equivalent of measuring our Universe's triangles by looking at a picture of the early Universe, and studying the spatial relationship between different points on that picture.

宙学家进行了类似实验，通过观察早期宙图像，图中不同点之间空间关系来测量我们宙三角形。

The third option is that gravity is just right critical density is the cosmologists' term for it and that it will hold the universe together at just the right dimensions to allow things to go on indefinitely.

第三种可能是，引力恰如其分就是宙学所谓临界密度它把宙控制在一个恰当范围，使事物永远继续下去。

Cosmologists have found a way to picture the universe in its entirety — confirmation of the tremendous power of making maps.

宙学家已经找到了一种方法从整体上来描绘宙——这是对强大绘制力量证明。

So as cosmologists what we do is we apply Einstein's theory of relativity to the universe as a whole.

作为宙学家，我们要做就是把爱因斯坦相对论应用到整个宙中。
