What is the origin of the universe? What was there before the
universe appeared? We are currently witnessing a second Copernican
revolution: neither our Earth and Sun, nor our galaxy, nor even our
universe, are the end of all things. Beyond our world, in an
endless multiverse, are innumerable other universes, coming and
going, like ours or different. Fourteen billion years ago, one of
the many bubbles constantly appearing and vanishing in the
multiverse exploded to form our universe. The energy liberated in
the explosion provided the basis for all the matter our universe
now contains. But how could this hot, primordial plasma eventually
produce the complex structure of our present world? Does not order
eventually always lead to disorder, to an increase of entropy?
Modern cosmology is beginning to find out how it all came about and
where it all might lead. Before Time Began tells that story.
This book attempts to explain why 'string theory' may provide the
comprehensive underlying theory that describes and explains our
world. It is an enthusiastic view of how compactified
string/M-theories (plus data that may be reachable) seem to have
the possibilities of leading to a comprehensive underlying theory
of particle physics and cosmology, perhaps soon. We are living in a
hugely exciting era for science, one during which it may be
possible to achieve a real and true understanding of our physical
world.
A short introduction to Modern Cosmology with a look at some of the
solutions to cosmological problems
