Three Roads to Quantum Gravity
- Three Roads to Quantum Gravity
"Three Roads to Quantum Gravity" is a 2001 book by theoretical physicist Lee Smolin. He discusses three potential approaches by which a unified theory of quantum gravity, arguably the foremost issue in theoretical physics, may be realized. Approaches discussed include string theory, M-theory, and Smolin's preferred approach, loop quantum gravity. Smolin insinuates that these approaches may be approximations of a single, underlying theory.
