Gentlemen:  I am 60 years old and in my life I have had many unpleasant realities revealed to me.  One, which I will use to make my point here, was when I face an entire second grade class of students ALL of whom firmly believed the human race regularly travelled to the stars because they saw it every week on "Star Trek".  To finish, if it is fiction in violation of physical law I believe it is simple common sense to label it as such because "no one would believe that" just doesn't happen in the real world.
