Science
From Graphology
In science, all events that are observed must be repeatable and produce the same results in order to uphold natural laws. If something cannot be tested, observed, and tested again, then it cannot be proved by the typical scientific method. Science must be able to test that which is falsifiable. This means that the hypothesis can possibly be proved false through the testing process. The scientific method involves observations, then hypotheses, which are possible answers as to why something happens the way it does. Through testing and observation, the possible answers to a given problem are eliminated (falsified). After a period of time, the hypothesis which stands the testing may become a "theory" (a term which, in science, denotes a stronger sense of truth than an opinion).
