A fascinating account of current theories on the way the universe will come to an end

The last three minutes of the universe has been the subject of much scientific and lay speculation for many years. Now, Paul Davies clearly and concisely sets out the arguments for three possible outcomes:

1) the universe will go on expanding indefinitely
2) it will slow down and eventually collapse into a zero space, the reverse of the Big Bang
3) it will reach a steady state neither expanding nor contracting but staying the same forever

As a religious man, Davies is equally curious about the implications for humans: is there any sense in which humanity can expect to survive for eternity?
