Non-perturbative Quantum Gravity

Non-perturbative quantum gravity is an approach to understanding gravity by directly quantizing spacetime without relying on small, approximate calculations. Unlike methods that treat gravity as a tiny correction to other forces, non-perturbative techniques aim to capture the full quantum nature of spacetime, especially in extreme conditions like black holes or the Big Bang. They often involve mathematical frameworks, such as loop quantum gravity, that describe space itself as made up of discrete, interconnected parts. This approach seeks a complete, consistent theory that unites quantum mechanics and general relativity, providing insights into the universe’s most fundamental fabric.
