Spacetime can be interpreted as the surface of an ndimensional superfluid.

时空可以用一个N维超流体表面来解释。

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

我要去听基普? 索恩博原子时空讲座。

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理有了更深了解。

And it might even hold the key to understanding the nature of spacetime itself.

它甚至可是理解时空本身本质关键。

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速度更慢。

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

现在我相信时空和物体是真实存在。

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，将时空视为种过冷液体理论。

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，这是宇宙物理极限，是时空延伸。

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

最终，只有在物理和时空极端情况下，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）上重大发现, 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，来推断在我空间时间之外 有什麽存在（如果有话）。

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理学，但我这里讨论不是时空结构中巨大涟漪！

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

这就是人谈论第四维度时意思，也就是时空。

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

但这就是我现在所知道一切了，据我最好推测，也参考目前最合理时空理论。

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

这就是时空本身如何为加速提供参考点方式。

These two principles led Einstein to conceive of a link between time and space, also known as spacetime.

这两个原理爱因斯坦设想了时间和空间之间联系，也称为时空。

They  only look like they curve around because they are travelling through a curved spacetime.

它看起来只是弯曲，因为它正在穿越弯曲时空。

In flat regions of spacetime, like, if there's no energy or matter nearby, objects traveling along parallel paths stay along parallel paths.

在时空平坦区域，例如没有量或物质附近，沿平行路径运动物体就会停留在平行路径上。

They might communicate with each other using neutrinos, or ripples in spacetime, or quantum entanglement, or some method we can't even imagine.

它可会用中微子、时空波纹、量子纠缠或一些我甚至无法想象方法相互交流。
