"The geocentric model of the solar system is an example."

The laws of physics are valid in any frame. They never had a theory, only observations. A hypothesis, or theory describes the interactions. The data is just the data.

"The germ theory of disease was another paradigm shift from previous tested theories."

Their were no theories before the scientific method could be applied. The paradigm shift was not in desease theory, it was in the applicaiton of the scientific method to uncover the truth of the matter.

"Their were no theories before the scientific method could be applied. The paradigm shift was not in disease theory, it was in the application of the scientific method to uncover the truth of the matter."

The scientific revolution started in the late 16th century. Even before the scientific revolution, physicians and medical researchers did follow procedures much like your OODA loops, for many years. They made some progress, but were limited because they were missing the mechanism of disease -- in large part because they lacked the instruments to see germs.

A microscope capable of viewing germs was developed in the late 17th century. Pasteur connected the dots in the 19th century -- by proposing the theory that germs caused disease.

Without the microscope germs could not have been seen, and the germ theory of disease would probably not have been developed. As we develop new instruments -- we will continue to modify theories or replace existing theories.

We don't know everything yet. We don't even know how much we don't know. The pace of scientific discovery has never been greater -- and it is increasing all the time.
