O.K. Later.
Not facts that dissolve into theory upon a close look.
Oh, this is gonna be tough. Excepting maybe a few trivial instances facts NEVER become theories and theories NEVER become facts. They are different sorts of things. Theories are explanatory. Facts don't explain anything in themselves, they just are as they are. Theories take some mechanism or model and, with associated principles, use it to account for why the facts are they way they are, and not some other way they might conceivably have been. Theory thereby makes demands upon facts -- that they must be this way, that they must not be that way -- so that facts can be used to test theories.
