Quantum gravity is a theoretical framework in physics that seeks to understand the nature of gravity within the framework of quantum mechanics. It is a field that aims to unify quantum mechanics and general relativity, two fundamental theories in physics that describe the behavior of particles at the smallest scales and the behavior of spacetime at the largest scales, respectively. Quantum gravity attempts to reconcile the principles of quantum mechanics, which govern the behavior of particles at the subatomic level, with the principles of general relativity, which describe gravity as a curvature of spacetime caused by massive objects. This field is still in its early stages of development and is a subject of active research in theoretical physics.
