loop quantum cosmology

Loop quantum cosmology (LQC) is a theoretical framework that combines concepts from quantum mechanics and general relativity to understand the universe's early moments, particularly during the Big Bang. In LQC, space and time are described as being made up of tiny, discrete units, much like atoms form matter. This approach aims to resolve singularities—points where current theories break down, such as the infinitely dense point of the Big Bang—by suggesting a "big bounce" instead, where the universe expands after contracting. Thus, LQC seeks to provide a new perspective on the universe's beginnings and its evolution.
