Part 6/15:
- Loop quantum gravity offers a different approach, suggesting that space itself is granular at the plank scale, composed of discrete chunks called spin networks. Here, space isn't continuous but built of indivisible units, effectively creating a quantum geometry that replaces the classical fabric of spacetime.
Both theories suggest the existence of a minimum length scale—near the plank length—beyond which traditional measurement and understanding break down, implying that the universe fundamentally resists probing beyond that boundary.
