Perhaps I should have said, "That's why there have been so many theories and theorems."
ie: https://en.wikipedia.org/wiki/History_of_electromagnetic_theory
Many folks are still wrestling with the High School level understanding, of shoving electrons around, in a conductor.
Such that do, are still stuck with theories proposed in the 1800s.
To help you understand the difference between a hypothesis and a theory, a copy/paste from another post:
The goal of the Scientific Method: to answer WHY observed phenomena occur.
The steps of the scientific method include:
1) asking a QUESTION about something you observe.
2) doing background research to learn what is already known about the topic.
3) constructing a, "hypothesis".
4) experimenting or testing the hypothesis.
5) OBSERVING the results
6)ANALYZING the data from the experiment and drawing CONCLUSIONS*.

When one of the Sciences runs into a phenomena, for which it hasn't yet figured out a method of testing (experimenting) the HYPOTHESIS, or: can't yet understand (analyze) whatever data might been found during experimentation, there can be no categorical, answer* to the question, "WHY?", and a, "THEORY" is proposed.
*Without definite conclusions, there can be no categorical answers.
"I suspect you might mean 'hypothesis' rather than theory."
