Which proves the mathematical nature of physics. That is the very definition of "proof".

Physics is not a natural phenomenon. It is a scientific discipline for studying naturally forming mathematical patterns and interactive functions.

Physics consists of modeling Universal

*constants* with human mathematics by measuring the physical expression of universal mathematical patterns and functions from prevailing relative physical values and mathematical functions.

The definition of Physics doesn't say anything about the nature of the universe. Mathematics do!
