What is quantum gravity? This fundamental question is still up in the air, despite decades of research and progress in the field. Quantum mechanics is used to understand microscopic phenomena, and a quantum theory of gravity is essential for understanding the origin of the universe and black holes. While the other known interactions have well-established quantum descriptions, gravity remains a mystery.
These questions have intrigued me since my student days. In my doctorate, I studied string theory, a consistent theory of quantum gravity. String theory posits that the fundamental particles are small vibrating strings rather than points. The theory is complex and has many open problems, but the attempt of this project is to systematically understand the holographic phenomenon, which describes physics in a volume by studying the boundary of space.
