"...the end of the Universe may be nothing more than evaporated black holes, darkness and a total entropy of energy."

But *IF* energy does evaporate from black holes, as theorized by Hawking, then perhaps it will again coalesce into clumps, then into larger clumps, then become heated and eventually become stars and begin a new & different Universe.
If 'energy' is only a collection of particles doing something, even at quantum levels, then it seems to me that rising ^above quantum levels is always an option.

(Mind you, my ideas are gleaned from TV programs and intution)

So...perhaps the piece, on paper, could end in coda, dal segno al fine .............................
