A fact is something that has occurred or is true and verifiable. It refers to an event, occurrence, or circumstance that has taken place in reality and can be observed or verified.
Facts are based on tangible evidence or proof, and they are independent of personal opinions or interpretations. For example, the fact that today is a day and that the Sun rises in the morning are objective and verifiable facts.
Facts are the foundation of knowledge construction and help us understand the world around us objectively.
