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

在最尺上，时空几何形状非常平坦。

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

我要去听基普? 索恩博士亚原子时空讲座。

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

特拉和史黛拉现在对时空工作原有了更深了解。

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

穿过弯曲时空光相对于外部观察者而言传播更慢。

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

现在我们相信时空和物是真实存在。

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

霍华德发明，谢尔顿计算，我原创，将时空视为某种过冷液论。

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，这是宇宙物极限，是时空延伸。

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

时空中最短路径是由测地线定义，即光在两个点之间路径。

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

最终，只有在物和时空极端情况下，才能使某物完全变成黑色。

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）上重发现, 表明极限重力可以引发时空涟漪。

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

空间或时空曲率。

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 将数学模型极限向外推，来推断在我们空间时间之外 有什麽存在（如果有话）。

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

目前，当时空变得无限弯曲时，广义相对论就完全失效了。

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

这就是时空本身如何为加提供参考点方式。

As much as I love spacetime physics, we're not talking about  massive ripples in the spacetime fabric here!

尽管我非常喜欢时空物学，但我们这里讨论不是时空结构中巨涟漪！

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

最后，现实结构被撕裂到其核心，消除了时空本身。

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区域，而引力是时空弯曲。

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

这就是人们谈论第四维时意思，也就是时空。

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

与光子一样，引力波在时空中以光传播。

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一切了，据我们最好推测，也参考目前最合时空论。
