Is "scientific knowledge" actually most of the times "a goal this is aimed for but seldom actually reached? New planets are continuing to be discovered. The genetic code is just beginning to be unpacked. More positive benefits are being discovered for caffeine. In some senses, each phase of what we consider as "irrefutable knowledge" is re-studied, re-examined, and we pass from "one stage of scientific knowledge" to "another stage of scientific knowledge with new questions requiring yet more future studies" suggesting we are always at a point of incomplete knowledge awaiting funding of new hypothesis to extend that knowledge to a new degree.
