Quantum Space - Loop Quantum Gravity and the Search for the Structure of Space, Time, and the Universe (Relié)

This is an account of loop quantum gravity, a major approach towards that goal. It's a story of strange, grand, breathtaking ideas concerning the emergence of space, time, and the structure of the universe. It is also the story of two physicists — Lee Smolin and Carlo Rovelli — close friends who, together with their many colleagues, have spent 30 years working to establish LQG as a viable theory of quantum gravity.
Jim Baggott explains the basic ideas without recourse to mathematics, and draws on conversations with Smolin and Rovelli to capture the intense excitement of working at the forefront of theoretical physics. You'll never think about space and time in quite the same way again.
