comment How could spacetime become discretised at the Planck scale?
Thank you for your answer. I'll get reading the references you've supplied. I may be some time :S

comment What are the current (popular(ish)) approaches to modelling the quantum nature of spacetime at the Planck scale?
@kakemonsteret In the QM I've studied I don't recall ever coming across discretised space or time variables for free particles. I'm pretty sure they're continuous variables, or have I missed/forgotten something?

The quote in question is on page 203 but if required I will transcribe it onto here..

This is a question loosely based on a quote from Penrose's 'Cycles of Time'. I was trying to appreciate (at least in essense) the range of different theories that lead to a discretised spacetime, whether or not full GR has thus far been incorperated.
