Science is just what we can't yet prove to be wrong through observation. In other words, what we believe about the universe is only true because it works within the limits of our observation. If we could observe better, we would find that what we believe is not true -- not perfectly true -- it's merely true enough.<p>This happens over and over again, yet people still believe science and theories are facts. They aren't really facts in the sense that they are perfect, they are facts in that there isn't something <i>more</i> perfect -- yet.<p>We thought the world was flat, then we observed orbits. We thought orbits were round, then we found ellipses. We thought gravity was constant.<p>You know, when I think about constants, I think they are really just a number we put in there to compensate for the range of realities that we can't measure. The gravitational constant isn't really a constant, it's part of the fluid and movable function that comprises the portion of the numbers we can't observe yet. There is a lot of change going on in there that we can't detect or believe to be wrong. That 9.8 meters per second squared actually changes while the objects are moving, yet 9.8 is good enough.<p>That's what science is: good enough.
