- Some questions about LQG and the earliest periods of our universe

From the german Version of Carlo Rovellis book "La realtà non è come ci appare. La struttura elementare delle cose" I have learned about the theory of Loop Quantum Gravity that

Or on the other hand, are these theories mutually exclusive? But for me it's hard to understand that there should have been an infinite series of universes with Big Bounces as transitions. Because the infinite series seems to end with the accelerated expansion of our universe and so we would live in a very special cosmos that differs from all the others.

By the way: no space in the Planck epoch => no size => no initial singularity ?

- space and time arise through the interactions of gravitational quanta,
- the space quanta have discrete volume spectra,
- there is a lower limit for size,
- there is a repulsive force at minimum size (of space quanta?).
