Description: Quantum gravity is a field of theoretical physics that seeks to unify gravity, described by Einstein’s general relativity, with the principles of quantum mechanics. This approach is fundamental to understanding phenomena that occur at extremely small scales, such as those found inside black holes or at the moment of the Big Bang. Quantum gravity attempts to resolve inconsistencies that arise when applying the laws of quantum mechanics to systems where gravity is intense. Unlike classical theories, which treat gravity as a continuous force, quantum gravity suggests that space and time may have a discrete structure at very small scales, implying they could be composed of minimal units, or ‘quanta’. This field of study is not only theoretical but also raises profound questions about the nature of the universe, causality, and the structure of spacetime. Quantum gravity is an active area of research, with various approaches, such as string theory and loop quantum gravity, each trying to provide a coherent description of how gravity and quantum mechanics interact in the universe.
