The Last Three Minutes:

What is the ultimate fate of the universe? Will it die with a bang or a whimper? Or might it live forever? This book examines several scenarios for the exceedingly far future, when the stars have burned out and black holes roam the cosmos. Read about super-civilizations eking out a desperate existence in the cold emptiness of space, or bracing themselves for fiery annihilation in the big crunch. But don't get depressed: there is hope that advanced being could create a new baby universe and de-camp to it... Wild stuff!
