Just another platitude. <yawn>Yes, many things have been discovered without knowledge of the laws of physics. But nothing has ever been discovered, knowledge or no knowledge, that violates those laws.
What's your point?
Many things have been discovered which violated the "laws" extant at the time of their discovery, and then the laws were changed to account for the validity of the discovery.
A few examples would be Copernicus's rejection of geocentrism, for the support of which Leonardo paid dearly, Michelson and Morley's interferometers, which ultimately dispelled the notion of the luminiferous aether and, of course, Einstein, who took Newton's insights to their limit.
