Falsification - The correctness of a hypothesis depends on how it is empirically proven. A hypothesis is considered falsified (refuted). if at least one case is found in practice that is inconsistent with the hypothesis. The final acceptance of a hypothesis would only be possible if all the events affected by it were checked in reality and were compatible with the hypothesis. However, such a check is usually not feasible. It is therefore impossible to claim general validity from scientific hypotheses or theories.
The criterion for the scientific nature of a hypothesis is the possibility of its falsification (power criterion). A hypothesis is sustained until it is empirically refuted. The fact that hypotheses can be falsified but not verified is called the asymmetric between falsification and verification. Anyone who engages in science must accept that there is no ultimate truth.
