Well, that depends. :) If it really is a fact, then yes... but people sometimes think that things are facts and they really aren't, so people argue about things like that. In the past, people thought it was a fact that the world was flat... but then we found out it wasn't. Scientists, even now, argue over what things are fact and which aren't.
