Sure would.  The Second Law is the only law that has a time direction
associated with it; all other laws are symmetrical in time (though
some of the new grand unified-field theories may not be).  As I said
before, pair production out of the vacuum can be thought of as
particles traveling in loops in space-time, but they're random, with
no information content.
