From Eric Kvaalen
It is true that if there is a big crunch with high order (low entropy), then
time will run backwards as we approach it
(5 February, p 26). But there is no
strong reason to assume that a big crunch would be highly ordered. Hawking
discusses this in A Brief History of Time— he once assumed that a
big crunch would be well ordered, like the big bang, but eventually realised
that physics does not require this.
And could there be future boundary conditions even in the real Universe,
which is apparently not headed for a big crunch? This could explain such things
as premonitions and even the origin of life.
