A few days ago, I heard a song on the radio whose chorus was, "When time was young."  That got me thinking: does time get "old"?  In other words, once time began--and how can time just "begin"?--however, did it ever have age?  Could it be young, then old?  It's not as if time experiences entropy, becoming progressively more corrupt as it "ages."  Although whatever may experience time certainly ages, time itself, it seems, does not.
     A number of years ago, a philosopher named Jim Holt published a book titled Why Does the Universe Exist?  After interviewing the finest minds on the planet about this question, he concludes that he really doesn't know.  One "day" the universe began, and one "day" it will end.  And that's all.  So said the great British philosopher and mathematician Bertrand Russell, too:  the universe "just is."
     But this doesn't answer the question:  how can time suddenly "be" and then, eventually, "not be"?  It's funny:  although we are creatures of time, we really know very little about what it means.  We live, we die, we are no more.  And "time" remains.
     Where, in a universe unable to birth itself, does it go?
