Objective facts are pieces of information that can be verified and are not influenced by personal feelings or opinions. For example, the statement "Water boils at 100 degrees Celsius at sea level" is an objective fact because it can be tested and proven through scientific methods. Another example of an objective fact is that Earth orbits the Sun once every 365.25 days. This information is based on astronomical observations and calculations, making it a reliable and factual statement that does not change based on individual beliefs or perspectives.
