The things everyone should know about time.
關于時間,每個人都該知道的事。
Disorder increases as time passes.
隨著時間的流逝,宇宙的無序程度會上升。
At the heart of every difference between the past and future—memory, aging, causality, free will—is the fact that the universe is evolving from order to disorder.
在過去與未來的所有差別——記憶、衰老、因果、自由意志——背后,隱藏著一個核心事實,那就是宇宙是從有序逐漸走向無序的。
Entropy is increasing, as we physicists say. There are more ways to be disorderly (high entropy) than orderly (low entropy), so the increase of entropy seems natural.
或者如物理學家所說:“熵(動力學方面不能做功的能量總數)在不斷增加。”達到無序狀態(高熵)比達到有序狀態(低熵)的途徑要多,因此熵的增加看起來再正常不過。
But to explain the lower entropy of past times we need to go all the way back to the Big Bang.
但要解釋宇宙曾有過的低熵狀態,就必須回溯至最初的宇宙大爆炸。
We still haven’t answered the hard questions: why was entropy low near the Big Bang, and how does increasing entropy account for memory and causality and all the rest?
我們仍然不能回答如下問題:為何在大爆炸之時熵如此低,以及熵增如何導致了記憶、因果以及其他一切。
【知識點講解】
