TOE must be a mathematical original set theory, because set is the most universal structure and only mathematics has sufficiently abstract method. Physics has no chance to discover TOE, because it studies only a part of natural phenomenons.
TOE must be built as an axiomatic theory, because the axiomatic principle is the only one scientific approach in building scientific theories. TOE's axiomatic system must be without contradiction and it must be independent ( it means that this system needs not another information beside this system to "work" ).
