Yup I sure do know the difference between FACT, THEORY and HYPOTHESIS.
A "FACT" is an observed, independently repeatable, inductively provable observation or formulae, which if discreditted requires a complete revamping of all related known knowlege - the existance of atoms is a "fact"
a "THEORY" is an observed, independently repeatable, inductively provable observation or formulae which encompasses all known relevant observations but which could be discreditted without a revamping of all related known knowledge, instead only requiring a new theory. - quantum mechanics is a theory, evolution is a theory
a "HYPTOTHESIS" is an unproven idea that matches some observations and can be discreditted with no impact on either existing knowledge or theory. There is life on Alpha Centauri is a hypothesis. Intelligent Design is a hypothesis.
The difference between 'FACT' and 'THEORY' is very slim. The difference between THEORY and HYPOTHESIS is a vast gulf.
