Foundations Of Quantum Gravity Guide

Instead of strings, LQG suggests that space itself is made of discrete "loops" woven together. In this view, space is not a container but a network of relationships.

These are regions where massive gravity meets tiny scales. A quantum theory of gravity is needed to understand what happens at their centers. Foundations of Quantum Gravity

Proposes that everything in the universe is made of tiny, vibrating strings of energy. It requires extra dimensions of space that we cannot see. Instead of strings, LQG suggests that space itself
