Maybe closed timelike curves aren't closed at all?

合的类时间曲线根本不是合的？

In a closed timelike curve, when you travel to the past, you've always been a part of that past.

在一个封的时间曲线中，当你回到过去，你就一直是过去的一部分。

Without getting into too much detail, a time machine like a Tipler cylinder could create a closed timelike curve.

简单，提普勒柱体这样的时间机器可以创造出一个封的时间曲线。

We don't understand quantum physics enough to know if these closed timelike curves could or couldn't exist.

我们对量子物理学的了解还不够，不知道这些封的时间曲线是否存在。
