The fact is that evidence isn't proof.
Realistically speaking we haven't nailed down quantum mechanics. We know things about it, but if I were to draw a comparison I'd say we're about where we were with deterministic physics pre-Einstein--which isn't to say that we know nothing, but rather is to suggest that what we're dealing with is likely to be vastly oversimplified.
That's quite a harrowing thought for anyone who has a bare minimum of expertise with quantum physics, because the model we have now is thoroughly complicated and difficult to work within.
It's important to understand that this "error code" is nested within equations which are meant to describe not one, but two, theories which remain 100% unverified and which are next-to-impossible to to experiment with or verify/falsify.
This doesn't qualify as science (science must be testable and repeatable as a bare minimum for entry). It is, instead, a very advanced mathematical exercise. It's mathematical modeling at it's best, but that doesn't always tell the whole story. In fact, for most systems we find that math is typically vastly oversimplified. Math suffers from something known as ideality bias, which is to say that--because there are so many objects to model, all the way down to quantum particles--it is very difficult to nest a REAL description of the world into an equation. When we model systems mathematically and then go test the results, what we often find is that there is a range of values wherein the model predicts quite well the behavior of the system--however there is a limit to the ideality of the system. Outside of the ideal range we must use MUCH more advanced mathematics to describe the state of a system. This is true for even the most BASIC of equations and well understood physical concepts. Take the gas law for instance, essentially the basis for all thermodynamics.
This law, after a great deal of testing, has become known as the
ideal gas law. Unfortunately, ideal gasses and the conditions which describe them are extremely diminutive and fail to describe most of reality.
Instead, to describe a much large portion of gas behavior we use the following equation:
It is often posited, and very likely to be the case, that string theory will ultimately also be found (if it is ever confirmed in the slightest) to suffer from this ideality bias. Ultimately it is likely that, as with the gas equation, a whole slew of "fudge factors" will need to be added in order to make good predictions about the system. The truth is that with real systems the math very often doesn't work out perfectly. It's only meant to be used as a model which can guide discovery, not as an absolute answer to the questions of the universe.
