i think its quite well established that space and time break down as approximations at the small scale. i also think that gravity is interesting because in GR there really isn't such a thing - its an artefact of the geometry of space and time - because of how we perceive the passing of time. i'm not sure exactly how time would fall out of gravity... afaik the quantum mechanical descriptions usually break the magic trick of GR and make it into a graviton field, which depends on some background time. i do wonder why we pursue theories which our existing theories show to be unlikely to be fundamental... thinking about the limits, near the planck scale we find that it is impossible to tell if an event is before or after, or if a thing is one or two things, or if its seperated in x or y... the simple conclusion imo is that space and time are approximations that are useful at everyday scales, but have no physical reality.
