So, our concept of distance is nothing more than the interaction of particles between each other?

edit: Through their respective field - I'm guessing, and does each force have its own field, or do they also interact with each other?

Yes. This is expressed by reversing Einstein's aphorism:

Spooky distance at an action.

Interaction events create the space-time interval between them.
