What does it mean when a hypothesis is falsifiable?

A hypothesis is considered falsifiable if it can be tested and potentially proven false through observation or experimentation. This means there must be a possibility of evidence that could contradict the hypothesis, allowing it to be evaluated scientifically. Falsifiability is a key criterion in the scientific method, as it distinguishes scientific claims from those that are untestable or purely speculative. In essence, a falsifiable hypothesis enables the pursuit of knowledge through rigorous testing and validation.
