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 the, "HYPOTHESIS", and 5) observing the results 6)ANALYZING the data from the experiment and drawing CONCLUSIONS*, and 7) communicating the RESULTS to others.

INVARIABLY: 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.
*English 101: without an answer, there can be no conclusion
As an example: I've repeatedly mentioned that Science has no ANSWER or CONCLUSION as to what exactly makes up 96% of this universe, BUT: since Einstein's cosmological constant problem, Physicists/Scientists have been THEORIZING and spending BILLIONS, in search of an ANSWER as to WHAT'S UP?
