i have the elegant universe and am about half way through. after this, i would like to read about string theory's rival, loop quantum gravity. does anyone know of a good intro book to loop quantum gravity?

I greatly enjoyed this link you gave us :http://cgpg.gravity.psu.edu/people/...r/articles.html , I printed out about 4 of the articles. Like the : "The Duel: Strings versus Loops" ! How much closer can you get to my essay?
Thanks,

Loop Quantum Gravity is a theoretical framework that attempts to reconcile the theories of general relativity and quantum mechanics. It proposes that space and time are quantized, meaning that they are made up of discrete, indivisible units, rather than being continuous as described by general relativity.
A "good book" on LQG can provide a comprehensive and accessible introduction to the topic, as well as serve as a valuable resource for further study. It can also help to clarify any misconceptions or misunderstandings about LQG and its implications.
LQG differs from other theories, such as string theory, in its approach to quantizing space and time. While string theory proposes that particles are made up of tiny, vibrating strings, LQG suggests that space and time are made up of discrete loops. Additionally, LQG does not require extra dimensions, as string theory does.
Some prominent scientists who have contributed to the development of LQG include Abhay Ashtekar, Carlo Rovelli, and Lee Smolin. Other notable figures in the field include Jorge Pullin, Thomas Thiemann, and Martin Bojowald.
Currently, there are no experimental tests or observations that definitively support LQG. However, there are ongoing efforts to develop experiments that could potentially provide evidence for or against the theory, such as gravitational wave detectors and studies of the cosmic microwave background radiation.
