A scientific fact is an observation about the natural world that has been repeatedly confirmed through rigorous testing and is accepted as true for all practical purposes by the scientific community. It is based on empirical evidence gathered through systematic and controlled experiments or observations, making it objective and verifiable. Scientific facts serve as foundational data points upon which hypotheses, theories, and laws are built. However, scientific facts are not considered absolutely final; they can be modified or discarded if new evidence emerges. This reflects the dynamic and self-correcting nature of scientific inquiry

. In summary:

• A scientific fact is a repeatedly confirmed observation accepted as true.
• It is supported by empirical evidence and rigorous testing.
• It is objective and verifiable.
• Scientific facts underpin scientific theories and laws.
• Their acceptance is provisional and subject to revision with new evidence.

This definition distinguishes scientific facts from hypotheses (tentative explanations) and theories (well-substantiated explanations that organize facts and make predictions)
