Quizplus · Accepted Answer

For a theory or prediction to be falsifiable, there must be evidence that could potentially prove it false. This means it must be testable and open to empirical observation. A theory or prediction that is impossible to test is not falsifiable. Additionally, just because a theory or prediction has not been proven false does not mean it is unfalsifiable. Finally, the fact that a theory or prediction comes from pseudoscience does not automatically make it unfalsifiable.
