"A meta-math function will define and help to find the fundamental nature of the universe" if something has taught us the scientific method during the last centuries is that mathematical/philosophical approaches cannot say us which is the fundamental nature of the universe. The history is full of skeletons of mathematical ideas that looked ok in paper, but do not describe universe.
Mathematics aren't the basis of the universe. Feynman explained the difference between mathematics and physics in his lectures.
"The scientific method does not prove a hypothesis true, but can only determine if something is false. The more a hypothesis or theory is tested the more certain we can be of its "truth", but absolute certainty will never be found by science". I disagree. We can prove hypothesis. E.g. Newtonian laws of motion continue applying to day so well as they did about 300 years ago, because the hypothesis that they describe motion was proven, so it cannot be disproved. Also the concept of truth used in science is not the older concept of truth used in other disciplines. Something is true on science if the difference between what the model states and measurements is smaller than the margin of error.
I do not think evolution is a fundamental principle of biology. I think it can be derived from atomic-molecular biology. The scientific method and evolution are not the same process, not even close; one is a method invented by humans, the other is a natural process.
Science is a "human construct". This does not throw away the idea that science could be developed by non-humans. For instance aliens or machines. Robot scientists have already been created.
Science gives true answers to questions about Nature. It is other disciplines as Philosophy which never provide any relevant answer.
Despite what some claim, string theory is not science, it is a kind of New Age religion.
Obviously "the fundamentals of Physics" are "in doubt", otherwise we had found the final theory. But there is no problem with taking a set of basic fundamentals and work with them until some experiment show they are in reality derived concepts. All the formal structure that arises from assuming those concepts are derived will continue to work so well as it does today. That is why we teach thermodynamics and its principles today, despite those principles can be derived from more fundamental principles.
