I was just joking around, but it is an entirely open question. One of the big discrepancies between relativity and quantum mechanics is how they treat time.

In relativity, time can be distorted and depends on the frame of the observer: i.e. two events (A and B) may appear to be simultaneous to one observer, while A appears to have happened before B to another, and to a third B happens before A.

In quantum mechanics, if two events happen at the same time, that will also appear to be true regardless of reference frame.
