> Nobody is worried that concepts like time, charge, momentum, etc. will be discovered to be a silly, unfounded idea

While not overly worried, I have to confess that I'm at least somewhat worried. And somewhat convinced that our present conceptions of theses things will one "day" be turned on their head, in a way that might also seriously affect our everyday conceptions of them.

I would support adding a couple of properties to most if not all our established models; notably 1: known unknowns, and 2: unknown unknowns. It would seem a healthy antidote to the hubris that runs rampant among scientists, at least before they discover the ubiquity of these two properties (they usually do around the 50 year mark).
