Which of these theories—the "strings" of energy or the "loops" of space—do you find more ?

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. Foundations of Quantum Gravity

General Relativity treats spacetime as a smooth, continuous fabric. Quantum physics suggests that at the smallest scales (the Planck scale , about 10-3510 to the negative 35 power meters), everything should be "chunky" or quantized. Which of these theories—the "strings" of energy or

Proposes that everything in the universe is made of tiny, vibrating strings of energy. It requires extra dimensions of space that we cannot see. General Relativity treats spacetime as a smooth, continuous

The difficulty lies in how each theory views the stage of the universe:

While no single theory is yet proven, several major contenders offer different "foundations":
