Of course not. I was just trying to be clear in my own mind about the distinction between non-relativistic and relativistic QM.

If you recall, my original question asked if QM required a universal time. Would it be right to say that non-relativistic QM does, but relativistic QM doesn't?

On the other hand, could it be that non-relativistic QM, if misapplied, gives answers that erroneously indicate a need for universal time?

There never was nothing.
