This is a bit of a trick question, playing on the way we talk about time! Here's why:

* There's only one 1:00 AM tonight. Time progresses linearly.

* The phrase "go back" is ambiguous. It could refer to:

* Going back in time (which is impossible).

* Traveling to a different time zone. If you travel west, you might encounter a second 1:00 AM, but that's because you're in a different time zone, not because time itself is repeating.

Let me know if you'd like to explore time travel or time zones in more detail!
