Scientists explain all of these manifestations of the arrow of time in terms of entropy—loosely, the “disorderliness” of a system.
就约束力小的一致性而言，科学家把所有这些时间的箭头的表现解释为一个系统的“无序”。

时间箭头只能说明时间的方向性，它不能说明时间是直线的或一定指向未来。
But the particular aspect of time that I'm interested in is the arrow of time: the fact that the past is different from the future.
但是关于时间我感兴趣的一个方面是时间之箭：即过去与未来不同这一事实。
"Perhaps life clings to these patches where entropy is going up, since we need the arrow of time to exist," UC Davis's Albrecht said.
“也许生命需要熵值上升的这些地方，因为我们需要时光之矢存在，”加州大学戴维斯分校的阿尔·布雷特说。
Another exception is the "cosmological arrow of time," which points forward from the Big Bang in the direction of the universe's expansion.
另一个例外是“时间的宇宙箭头”，该箭头从大爆炸指向宇宙膨胀的方向，其可能与热力学箭头相连，指向宇宙最终的热寂。
The apparent arrow of time emerges as a property of the macroscopic system, but it's not there in the laws that govern the individual particle interactions.
很显然时间箭头成为了宏观系统的一种性质，但没有定律来控制单个原子间的相互作用。
To return to the arrow of time, there remains the question: why do we observe that the thermodynamic and cosmological arrows point in the same direction?
回头再说时间箭头，余下的问题是；为何我们观察到热力学和宇宙学箭头指向同一方向？
So inside those new universes, which move forward with the arrow of time, there are places where the laws of physics are different —anomalies in spacetime.
那些新产生的、沿着时间之箭前进的不同小宇宙里，存在物理定律不同的地方，比如时空异常。
So inside those new universes, which move forward with the arrow of time, there are places where the laws of physics are different — anomalies in spacetime.
那些新产生的、沿着时间之箭前进的不同小宇宙里，存在物理定律不同的地方，比如时空异常。
If you look at a movie that's being played backwards, you know it immediately because most things have a distinct time direction attached to them: an arrow of time.
假如你让电影倒带播放，你会发现任何事情都带有明显的时间方向性质，就像有东西拉着他们：时间箭头。
So if the arrow of time is based on our consciousness and our ability to perceive it, then do people like you who understand it more fully experience time differently then the rest of us?
如果时间之箭是基于我们的意识和感知它的能力，那么像你这样更充分地理解它的人与我们其他人相比是否有不同的时间体验？
To the right there's a drawing of Earth orbiting the Sun, with an arrow pointing to the right. The arrow means one year, the time of it takes the Earth to rotate around the Sun.
一个箭头指向球体右方，那儿有一个地球围绕太阳旋转的图样，这个箭头意味着一年，暗示地球围绕太阳旋转一圈的时间。
