Conversely, explanations based in supernatural causes are not considered to be scientific. Scientific hypotheses must be testable and falsifiable. Experimentation and observations can increase our confidence that a hypothesis is a correct explanation of a phenomenon, but can never absolutely prove a hypothesis to be true. The conclusions of science are subject to change. New studies, which might utilize new techniques and equipment, may reveal that previously accepted theories need to be modified or changed entirely.

Explanations are not testable and falsifiable Explanations are based on misconceptions, misinterpretations, or misrepresentations of scientific fact. It is indeed remarkable that this theory has been progressively accepted by researchers, following a series of discoveries in various fields of knowledge. The convergence, neither sought nor fabricated, of the results of work that was conducted independently is in itself a significant argument in favor of this theory.
