The epitome of a causal or anti-chronological behavior would be to see a clock running backwards in time. In this essay, we point out that this is indeed possible, but there is no problem with causality. What you see is not what is really happening. Locally, causality is always respected. However, our observation should be cause for pause to astronomers and cosmologists, who strictly observe events occurring at very large distances or very long ago and certainly not locally. It can be that what you see is not what you necessarily get.

你可以看到一个时钟在时间倒流

因果或反时间行为的缩影将是看到时钟在时间上倒退。在这篇文章中，我们指出这确实是可能的，但因果关系没有问题。你看到的并不是真正发生的事情。在当地，因果关系始终受到尊重。然而，我们的观察应该让天文学家和宇宙学家停下来，他们严格观察发生在很远距离或很久以前的事件，当然不是局部的。可能你看到的不一定是你得到的。
