Loop quantum cosmology these stages are so extreme that classical general relativity combined with matter theories is not able to describe them.
More humble view on quantum cosmology, which tends to be attracted to grandiose questions regarding the whole universe, everything in or about it and the origin. We first set up the problems to be solved by quantum cosmology. General relativity has shown that space-time is physical and dynamical and that it interacts with matter.
Quantum cosmology is the attempt in theoretical physics to develop a quantum theory of the universe.
This comprehensive textbook is devoted to classical and quantum cosmology, with particular emphasis on modern approaches to quantum gravity and string theory and on their observational imprint. It covers major challenges in theoretical physics such as the big bang and the cosmological constant problem.

Loop quantum cosmology (lqc) is an approach to cosmology within the framework of the loop quantum gravity (lqg) program (rovelli 2004), which itself starts with the idea that unifying quantum theory and general relativity will require “quantizing” the gravitational field—and hence the structures of spacetime itself.
In 1983, stephen hawking and james hartle developed a theory of quantum cosmology which has become known as the 'no boundary proposal'. Recall that the path integral involves a sum over four dimensional geometries that have boundaries matching onto the initial and final three geometries.
