It seems to me that ground-breaking discoveries in physics are generally getting more expensive. Up till about the early 20th century, ground breaking physics was largely "two guys in a garage" territory -- single individuals such as Newton or Cavendish tinkering in their own private laboratories using fairly modest equipment. Teenagers replicate their experiments in school physics lessons with equipment costing no more than a few hundred pounds today. Throughout the mid-twentieth century, ground-breaking discoveries were increasingly made by teams of researchers, which seem to have grown larger over time, with equipment that has become increasingly large and expensive, and sponsored by universities, companies and governments. Nowadays it seems that most ground-breaking discoveries are made by large, national or multinational teams working with equipment costing billions of dollars and processing petabytes of data. I couldn't see two guys in a garage producing their own space telescope or particle accelerator any time soon.
