Quantum Gravity is a theoretical framework that seeks to unify the principles of quantum mechanics with general relativity, providing a comprehensive description of gravity at the quantum scale. While general relativity explains gravity as the curvature of spacetime due to mass, it struggles to describe gravitational interactions at subatomic scales, where quantum mechanics dominates. Quantum gravity aims to resolve this discrepancy by developing a theory that describes the behavior of gravitational forces in extreme conditions, such as near black holes or the early universe. Leading approaches include string theory and loop quantum gravity, but a fully accepted theory of quantum gravity remains one of the greatest challenges in modern physics. Success in this endeavor could reveal new insights into the fundamental structure of space, time, and the universe itself.
