Quantum theory has history too
Atoms where it, then Atoms where sets of particles, then particles were waves/smaller particles/strings...
Quantum theory - we need a new particle, then we've found it, then we need another one... So are there just infinite possibilities? New model needed?
We're fish in a pond trying to work out where the water's coming from/going to - lots of models/theories will work, but without being outside looking in we'll never really know
