Look up and see a recent essay by the head of the Princeton Institute of Advanced Study where, for my rough summary from rough memory, he explained that physics can have lots of models that all fit all the data the same. So, it can be tough to find the one correct model, the one book of physics, the one way the universe runs, etc.
Then see a recent essay at Quanta Magazine that explains that physics has long looked to some largely esthetic concerns especially about symmetry to pick and choose among alternate theoretical explanations -- again my rough summary from my rough memory.
