Quantum Space: Loop Quantum Gravity and the Search for the Structure of Space, Time, and the Universe

Quantum Space: Loop Quantum Gravity and the Search for the Structure of Space, Time, and the Universe by Jim Baggott

Theoretical physics is something that smart people work on. Occasionally it has implications in the real world. After reading this book, I did not feel I had a better understanding of Quantum loop gravity. I did feel it was something that is still being debated that involved a different way of looking at the universe. Some things like gravitons could theoretically exist to help explain things, but would be almost impossible to measure. A lot of the work comes down to the details the get hidden away in the work of Einstein and Newton. It seems there are a some artificial complexities in the nomenclature. There is a lot of insularity in the theoretical physics community. The book focuses on a few physicists - mostly in Italy and Pennsylvania - as they use different methods to explore the physical world. It seems we are a long way from having a definite answer.
