CHAPTER

Challenges of Making Precise Statements in Quantum Gravity

This chapter explores the difficulties in making precise statements in the quantum theory of gravity due to the curved spacetime. It discusses the dependency of the quantum theory on the chosen method of slicing up space and examines two approaches towards addressing the issue of background independence. One approach is taken by loop quantum gravity, which aims for complete background independence, while the second approach is taken by string theory to develop a background independent approach.
