A guide to black holes and the more complex astronomical
Read August 3rd to 17th, 1989
Since I know I will not read this book again, I thought I should write
something about it here, in December 2000. What I remember most about
this book was Hawking's description of Time, and his explanation of cause
and effect. He described the Big Bang, and theorized on the Big Crunch,
if the Universe was to collapse in on itself again. People have speculated
that you would then see a broken glass reassemble itself and climb back
onto a table. But he discounts this by recalling that time can only
move forwards, so that Cause must always precede Effect. Even if
the Big Crunch does occur, time will still move forwards. I was awe-struck
-it all made so much sense.
So nearly ten years after this book was published, I was quite
disheartened when Hawking changed his mind and publicly stated that time
could move backwards.
