All the physics experiments in the world aren't going to give you insight into problems unless you have workable ideas for how to integrate the findings into understanding/knowledge.
What people often error in is that you can keep hacking away at and brute force your way to knowledge/understanding ...
“A theory can be proved by experiment; but no path leads from experiment to the birth of a theory.” — Albert Einstein
Ancient philosophers solved a lot of problems. More than you seem to be giving credit to. It's from their ideas that people knew where to look to 'prove' things. Watch the Feynman video and truly grasp what he is saying.
