After reading more about Loop Quantum Gravity. I realized they tried to solve quantum gravity by literally sweeping Planck scale under the rug. That is. The smallest volume and area of the spin networks in LQG is Planck size. In String Theory, they make the string Planck size too. They are just avoiding the Planck scale by literally blurring it by making their smaller *object* Planck size. This is not good mode of thinking. It's avoidance of the problem and ugly and both String Theory and Loop Quantum Gravity would likely fail (I'd bet off my Ipad they would fail).
Anyone knows of any QM/GR unification programme that explores and models what is inside Planck scale which can make GR and QM as its lower limit? This Third Theory of the dynamics inside the Planck Scale may be what can unite the QM/GR. In other words. Having both general relativity and quantum theory emerge from a theory very different from both. Planck scale may not contain normal spacetime. But maybe some kind of space just like what we had before the Big Bang expanded its spacetime. Only an exploration of this may give us the real Quantum Gravity and Unification of all forces. Or it is impossible or already refuted that inside Planck scale is some stuff that can have both general relativity and quantum theory emerge from it? How is this refuted if it has been refuted already? If not yet refuted. What is the best approach to explore the world inside Planck Scale? What below Planck scale models/theories already exist that have not been refuted yet?
