把这一句，留给此刻的你
Time travel may be achieved one day, or it may not. But if it is, it should not require any fundamental change in world-view, at least for those who broadly share the world view I am presenting in this book.
时间旅行可能有一天会实现，也可能不会。但如果是这样，它不应该要求对世界观进行任何根本性的改变，至少对于那些与我在本书中所阐述的世界观有着广泛共识的人来说是这样。
