> Any suggested reading on this topic for laypeople? Carlo Rovelli is a bona fide theoretical physicist, very involved in the development of Quantum Loop Gravity (one of the attempted approaches to bridge GR and QM). Turns out he is also a good pop-sci writer, so I would begin there. His book "The Order of Time" deals with the nature of time, which is not about the nature of space, but then again reading it you see that the mental gimnastics are similar. I also found useful contributions from regular contributors at /r/cosmology (thank you /u/jazzwhizz) but it's less straightforward and alas, Reddit has its own issues.
