Quantum Gravity at the Turn of the Millennium
arXiv:gr-qc/0011089
Abstract
A very brief review is given of the current state of research in quantum gravity. Over the past fifteen years, two approaches have emerged as the most promising paths to a quantum theory of gravity: string theory and quantum geometry. I will discuss the main achievements and open problems of each of these approaches, and compare their strengths and weaknesses.
