Oh, I'm gonna go see Kip Thorne give a lecture on subatomic spacetime.

我要去听基普? 索恩博士的亚空讲座。

Terra and Stella now both have a better understanding of how spacetime works.

特拉和史黛拉现在对空工作理有了更深了解。

Light passing through curved spacetime appears to travel more slowly relative to an external observer.

穿过弯曲的空的光相对于外部观察者而言传播的速度更慢。

On the largest scales, the geometry of spacetime is very flat.

在最大尺度上，空的几何形状非常平坦。

Now we believe that spacetime and objects are the nature of reality as it is.

现在我们相信空和物体是真实存在的。

Howard's invention, Sheldon's math, my original theory that spacetime was like a supercooled liquid.

霍华德的发明，谢尔顿的计算，我创的，将空视为种过冷液体的理论。

But that's not some illusion, it's a physical limit to the Universe, a stretching of spacetime.

但这不是什么幻觉，这是宇宙的物理极限，是空的延伸。

The shortest path in spacetime is defined by the geodesic, the path of light between two points.

空中最短的路径是由测地线定义的，即光在两个点之间的路径。

Ultimately, making something totally and completely black may only be possible at the extremes of physics and spacetime.

最终，只有在物理和空的极端情况下，才物完全变成黑色。

The finding, from the Laser Interferometer Gravitational-Wave Observatory, or LIGO, showed that extreme gravity can cause ripples in spacetime.

这一在激光干涉引力波天文台（LIGO）上的重大发现, 表明极限重力可以引发空涟漪。

All of these seemingly different phenomena can be described by one idea: curvature of space or spacetime.

空间或空曲率。

That said, cosmologists are pushing the limits of mathematical models to speculate on what, if anything, exists beyond our spacetime.

然而，宇宙学家还在 将数学模型的极限向外推，来推断在我们的空间间之外 有什麽存在（如果有的话）。

But this is all we know right now, from the best prediction we have, from our best current theory of spacetime.

但这就是我们现在所知道的一切了，据我们最好的推测，也参考目前最合理的空理论。

Finally, the very fabric of reality is torn to its  core, obliterating spacetime itself.

最后，现实的结构被撕裂到其核心，消除了空本身。

A singularity is a region of infinite gravity, and gravity is the bending of spacetime.

奇点是一个具有无限引力的区域，而引力是空的弯曲。

Like photons, gravitational waves travel at the  speed of light as they ripple across spacetime.

与光一样，引力波在空中以光速传播。

Currently general relativity completely breaks down when spacetime becomes infinitely curved.

目前，当空变得无限弯曲，广义相对论就完全失效了。

This is how spacetime provides a reference point for acceleration all by itself.

这就是空本身如何为加速提供参考点的方式。

That's what people mean when they talk about four-dimensional spacetime.

这就是人们谈论第四维度的意思，也就是空。

We can't mark specific points, or staple something to spacetime as an  anchor.

我们无法标记特定的点，也无法将些东西钉在空上作为锚点。
