Sounds like mysticism to me. You haven't defined x,y,z,t other than as mathematical coordinates, and you purport to describe the universe without even considering mass as a variable.
True, there is the axiomatic approach. Assume undefined variables, call them what you will, and assume a mathematical relation between them. Then associate the result with a physical reality. Depending on your mathematical creativity, you could explain almost any specific physical event that way and then claim the general truth of your "theory.".
