The scientifi c method, it could be said, is a way of learning
or a process of using comparative critical thinking. Things that
are not testable or falsifi able in some scientifi c or mathematical
way, now or in the future, are not considered science. Falsifi -
ability is the principle that a proposition or theory cannot be scientifi
c if it does not admit the possibility of being shown false.
Science takes the whole universe and any and all phenomena in
the natural world under its purview, limited only by what is feasible
to study given our current physical and fi scal limitations.
Anything that cannot be observed or measured or shown to be
false is not amenable to scientifi c investigation. Explanations
that cannot be based on empirical evidence are not a part of science
(National Academy of Sciences, 1998).
