Scott Adams wrote an interesting thing about scientific fact a few weeks ago.  One of his points was that scientific facts sometimes change based on how much "science" we know. 
But is a scientific fact the same as being true?

Sometimes a scientific fact is falsified by newer and better science. That's how science works. So while we assume it is rare, a scientific fact can be false in reality, especially in the short run.
I really don't like getting into that whole "evolution isn't a fact, it's a theory" argument, but I think it's worth noting that several widely held beliefs were later disproved: 
  1. Letting leeches suck your blood will cure disease
  2. The earth is flat
  3. The sun revolves around the earth
  4. Pluto is a planet
So while certain bits of information are considered facts or theories (depending on who you ask), those bits can change depending on what we know or how we define them. #religion
