So, in a metaphorical sense, entropy is arrow of time.

所以说, 我们可以这样作个比喻:熵像是时间之矢.

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。

Because we depend on the arrow of time just for our existence.

因为我们依赖时间之箭正是为了我们的存在。

The arrow of time is simply the distinction between the past and the future.

时间箭头的目的只是为了区分过去和现在。 我们能把一只鸡蛋变成一份煎蛋卷，但不能让一份煎蛋卷变成一只鸡蛋。

So that static universe in the middle has time as a coordinate but there’s no arrow of time.

所以这个处于中间的静止的多元宇宙具有作为坐标的时间，但是没有时间之箭。

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”。

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。

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”。

Once a system gets to its fully-disordered state -- its equilibrium -- there's no more direction of increasing entropy to determine the arrow of time.

一旦一个系统达到完全无序的状态—平衡态—再也没有更多增加熵的方向来决定时间的箭头了。
