Falsifiability

In the philosophy of science, falsifiability or refutability is a quality or characteristic of a scientific hypothesis or theory. Falsifiability is considered a positive (and often essential) quality of a hypothesis because it means that the hypothesis is testable by empirical experiment and thus conforms to the standards of scientific method. That something is "falsifiable" does not mean it is false, rather it means that if it is false, then observation or experiment will at some point demonstrate its falsehood.
