What is the difference between a scientific question and a non scientific question?

A scientific question is one that can be tested and investigated through empirical observation and experimentation, allowing for measurable outcomes and reproducibility. In contrast, a non-scientific question often deals with subjective opinions, beliefs, or values, and cannot be answered through systematic experimentation or observation. For example, "What causes gravity?" is scientific, while "Is love the most important thing in life?" is non-scientific.
