Objective facts are pieces of information that can be verified and are not influenced by personal feelings or opinions. They are based on observable phenomena and can be proven true or false through evidence. For example, water boils at 100 degrees Celsius at sea level, which is a measurable fact. These facts are essential in various fields, such as science, journalism, and law, where accuracy and truth are crucial. Unlike subjective opinions, objective facts provide a solid foundation for understanding the world and making informed decisions. For instance, stating that the Earth orbits the Sun is an objective fact supported by astronomical evidence.
