Falsification is the process of proving that a statement, theory, or hypothesis is false. It is a key concept in the philosophy of science, particularly associated with the work of Karl Popper. According to Popper, for a theory to be scientific, it must be testable and able to be disproven through observation or experimentation. In practice, falsification involves conducting experiments or gathering evidence that contradicts a proposed idea. If the evidence shows that the theory does not hold true under certain conditions, it can be considered falsified. This method helps scientists refine their theories and improve understanding of the natural world.
