Spinfoam

Spinfoam is a theoretical framework in quantum gravity that models space and time as a network of interconnected quantum states. Imagine space as a foam-like structure where these states evolve, with "spinfoams" representing the transitions between different configurations. They serve as a kind of path integral, summing over all possible geometries to describe how the universe's fabric behaves at the smallest scales. Essentially, spinfoams aim to unify quantum mechanics and Einstein's gravity, providing a way to understand the quantum nature of spacetime itself.
