Scientifically, what is the difference between an 'Hypothesis', a 'Theory' and a 'Fact'?

A fact is an indisputable observation of a natural or social phenomenon. We can see it directly and show it to others.

A hypothesis is an idea that we can test with further observations. We set out to gather evidence to see if our hypothesis is supported.?

A theory is a carefully constructed possible explanation for what we observe, drawing together many facts and hypotheses. Theories become stronger as they explain more facts. If a theory explains facts conclusively, it becomes accepted as the most likely explanation for the observed facts.
