That's entropy and the arrow of time.
这就是熵和时间之箭。
Carroll: The arrow of time doesn't move forward forever.
卡罗尔：时间之箭不会永远前进。
So, Boltzmann understood that and he explained how entropy is related to the arrow of time.
所以，波尔兹曼了解这一点并且他解释了熵是如何与时间之箭相关的。
This serves as a crude model of entropy, Smolyaninov says, representing the thermodynamic arrow of time.
可以看作是熵的粗糙模型，斯莫连尼诺乌说，它代表了热力学时间之箭。
The nub of the problem is that you cannot have a consistent “arrow of time” in the presence of closed timelike curves.
问题的关键在于在封闭的时间型曲线中没有一个连续一致的“时间箭头”。
Other theoriesforthe arrow of time are similarly incomplete.
其他关于时间之箭的理论也都不够完整。
The arrow of time is about a direction, but it's not about a speed.
时间之箭是关于方向的，而不是关于速度的。
The weird thing about the arrow of time is that it’s not to be found in the underlying laws of physics. It’s not there.
关于时间之箭奇怪的事情是在物理学的基本定律中并没有发现它，它不在那里。
The universe would be in a state of almost complete disorder. There would be no strong thermodynamic arrow of time.
宇宙将处于几乎完全无序的状态，这时就不会有强的热力学时间箭头。
The arrow of time can only show us the direction of time, it shall not tell us time is straight or time must go towards the future.
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。
"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。
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。
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。
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。
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 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？
