What is what does hypothetical mean?

Hypothetical refers to something that is based on a a hypothesis or assumption, rather than on actual facts or evidence. It is a way of discussing an idea or situation that is not currently real or present. For example, a hypothetical question might ask "What would happen if you could travel through time?", while a hypothetical scenario might describe a situation that has not yet occurred, such as "Imagine if a giant asteroid were to hit the Earth". In science, hypotheses are tested through experimentation and research to determine if they are true or false.
