When does knowledge become knowledge?

It would have to depend upon whether it is based upon reliable data, data which is properly organized about reliable presumptions, and whether it is provable by repeated testing, whether it is possible to prove it wrong, and whether there are contradictory conclusions which can be accounted for.

Knowledge is something which is knowable. It must be able to stand the test of time. In fact true knowledge is incontestable in the end.

We have been using radio active decay principles to date many of our artifacts. At first it seemed to be the basis for knowledge. But as more consideration has been made of its reliability, this method is failing a great many tests of ‘at least’ the application of its use without considering some serious variables.

Consider this link which brings serious doubt on one area of reliability and application. http://www.icr.org/article/5656/
