The unknown universe

A groundbreaking guide to the universe and how our latest deep-space discoveries are forcing us to revisit what we knowand what we don't. This is the first book to address what will be an epoch-defining scientific paradigm shift. Stuart Clark will ask if Newton's famous laws of gravity need to be rewritten; if dark matter and dark energy are just celestial phantoms? Can we ever know what happened before the Big Bang? Whats at the bottom of a black hole? Are there universes beyond our own? Does time exist? Are the once immutable laws of physics changing?
