When a succession corresponds to an intended event, it is considered a success. An unintended event, alternatively, is a failure. All events progress, including successful ones, and, consequently, successes eventually fail. Successful events, alternatively are accepted and processed over indefinite periods. It is particularly the obligation of theoretical science to push successful theories to their failures.
Theoretical science makes no major advance until it forces failures.
Out of the failures, new advanced theories are proposed and the effort to push the new theories to their failures begins. Theoretical science learns as its theories fail. Notice that I did not say science advances as scientists fail. The failure of scientists to theorize, test, and apply theories is simply a process of failure, not success. The process of success pushes theory to its failure through testing, development, and application.
