Science means the production of testifiable testimony.
Science functions by the competition for survival between testifiable testimonies in the market for testifiable testimonies that consists of other scientists.
Not all scientific publications or claims survive even the initial test of testifiable under the most basic competitive scrutiny.
Some survive partly for a time. Some survive partly for a long time. But cumulatively over time those some or all of some hypotheses and theories survive replication, application, and survival in both application and competition from new testifiable testimonies whether hypotheses or theories.
The progress of this competition for survival, over time, increases the unambiguity(identity), parsimony, consistency, correspondence, and causality of the set of surviving testifiable testimonies (claims, first principles, laws).
At some point maximum reducibility within a domain is discovered, consisting of textual first principles or or mathematical law, resulting in settled science. (chemistry)
At some point we
Therefore Science is merely the application of western tradition of court testimony from civil and criminal matters to mere disputes to hypotheses and theories about the universe and all within it.
This means that Science is an extension of jurisprudence, and progresses as does jurisprudence, and as a consequence of all knowledge, by Darwinian evolutionary process applied to thought using words.
Science is just testifiable testimony.
Non-Science is untestifiable.
ANd to claim the unjustifiable is true is always and everywhere to lie.
One can claim supernatural faith.
One can claim reasonable belief
One can claim habitual trust
One can claim experiential confidence
One can claim the certainty exhaustive knowledge and experience.
But none of those terms are the same as ‘true’.
Only testimony that is testifiable, because it satisfies the demand for realism, naturalism, identity, consistency, correspondence, constructability, reciprocity, and full accounting within stated limits can be claimed “true”.
