No wonder many of today's philanthropists aim, as Carnegie did, to give away all their money by the time they die, or at least put a time limit on the lifespan of their foundation after their death.

As time goes by, flowers come out and pass away, birds sing and die, and human being's simple motions change a lot, but my dreams from one to another last again and again.

Matter begins to convert into energy, space field vanishes first, And time field will die away in the black holes formed after the collapse.
