But we know for a fact that the laws of physics as we know them today are not correct. > If you > disagree then it's up to you to point to just a single example of such a > process and write up an article that proves your point and get that > published in a per reviewed journal. > Quantum field theory does not include gravitation. I don't have to write a paper about this because many people have already done so.

The Born rule is a prime example -- it is just imposed on the quantum wave function in an ad hoc way -- it cannot be derived from the fundamental theory.
