把这一句，留给此刻的你

And time itself? Time was a never-ending medium that stretched into the future and the past - except there was no future and no past, but an infinite number of brackets, extending either way, each bracket enclosing its single phase of the Universe.

和时间本身?时间是一种无限延伸的媒介，它延伸到未来和过去——除了没有未来也没有过去，而是无穷无尽的括号，向任何一个方向延伸，每个括号都围绕着宇宙的单一阶段。
