> Example: what if it turned out that time itself had qualities no-one had suspected before? Time is one of those fundamental things in existence that may (or likely will) still reveal some previously unknown aspect. Which in turn would likely affect our perception of all things in existence.

The validity of Newtonian mechanics didn't change because we discovered relativity just like the equations of motion don't become invalid because there's friction. It's still useful, we're just more familiar with the boundary conditions where it breaks down. It's unlikely we'll ever throw it away because it is the simplest model with a lot of predictive value at low energies.
