I'm a lay person reading Three Roads to Quantum Gravity. I like the book very much but do have trouble understanding parts of it. Hopefully I can find clarification on a point of confusion for me.
I thought loop quantum gravity was based on relational spacetime - that spacetime wasn't actually a "thing" but a phenomena experienced from the relative events in the universe. Yet, in the postscript, it is said that there is a "possibility of observing the atomic structure of space itself". But, from a relational view, there IS no "space itself", right? Isn't "space itself" the language of an absolute view?
