Loop quantum gravity is a theoretical framework that attempts to reconcile general relativity and quantum mechanics. It suggests that space and time are not continuous but instead made up of tiny, discrete units, much like atoms form matter. This approach aims to describe the fabric of the universe at the smallest scales. In loop quantum gravity, the geometry of space is represented by loops, which are interconnected in a network. This means that the structure of space can change and evolve, leading to new insights about the nature of black holes and the early universe. The theory remains a work in progress, with ongoing research to validate its predictions.
