Dear Wanpeng,
Thank you for reading my essay.
I am familiar with the theory of the Lewandowski Group and Caro Rovelli. He argues that space-time is structurally somewhat similar to a fabric, it consists of a large number of very small fibres entangled in LOOPS. My perception of space-time-gravity is that it is an emergent phenomenon originating from Total Simultaneity. The seemingly Flow of time and space as an emergent conscious agent is experiencing is an illusion. It originates from time-space-gravity and dimensionless eternal Point
Regarding the connection that you are indicating to quantum-Planckian, it is indeed the Quantum length and time that are for me (as yet) the borders of our emerging phenomenon called reality. I argue that from an emergent phenomenon the Planck length and time cannot be reached and so they are the limits of our reality (illusion).
best regards
