Or, to take a more recent example, phlogiston.
From ancient Greece to today is a mere ~2500 years (and ~500 from phlogiston); did the universe change so dramatically in such a short time? Or did we?
If we could fast forward 500, or 2500, years, how much like phlogiston, or earth/air/water/fire, would 'photons' and 'Feynman diagrams' seem?
An easier way to see this: between the proton and the top quark is what, ~2 OOM (in mass)? Add in the electron, and it's ~5 OOM. When the LHC comes on stream, we will get up to ~10 TeV, which will be another ~2 OOM.
Look at all the richness of the universe, in those ~6 OOM!
