What is uantum gravity?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
uantum gravity is a theoretical framework that attempts to describe gravity according to the principles of uantum mechanics. Currently, gravity is explained by Einstein's general relativity (which works beautifully at large scales), while uantum mechanics governs the atomic and subatomic world. However, these two theories are fundamentally incompatible. uantum gravity seeks to unify them into a single consistent theory that works at all scales, especially at the extremely small Planck scale where both uantum effects and gravity become significant. Leading candidates include string theory, loop uantum gravity, and others, but a complete, experimentally verified theory remains one of physics' greatest unsolved challenges.
