Just to Let You Know

A "theory" in the scientific sense is an explanation of a phenomenon that has been tested and verified through observation and experimentation. A "hypothesis" is an explanation of a phenomenon that has not yet been tested or verified.--Mr Fink (talk) 17:21, 29 December 2012 (UTC)
