- A thorough explanation of a significant aspect of nature that is supported by data acquired through time is referred to be a theory. Predictions concerning occurrences that have not yet been observed can also be made by scientists using theories. A scientific theory is a well-supported explanation of a particular phenomenon in the natural world that is based on a body of facts that have been repeatedly verified via observation and investigation.
