How can we test a theory of everything?

Here are two possible, rather different, answers:

- Use the theory of everything to calculate and then to measure deviations either form the standard model or from general relativity. Compare the results.

- Use the theory of everything to calculate the constants of the standard model (the mass of the electron, 137.03, muon mass, quark masses), and compare the calculation results with measurements.

it's almost the 2nd answer. How it could be different? Basically, the theory must predict all the experiments outcomes, but not necessarily with the previous paradigms. In such theory, one can imagine that old constants lose a part of their meaning and that new constants appear; ideally, a set of the needed background pure math theories.

Now, for many aspects, the SM is a TOE. Thus, I think you are meaning a single small set of axioms from which all the sub theories can be derived without fundamental additions. Why does it exist and weither is it reachable today are open questions.

In order to formulate a theory of everything one must carry out the experiements of everything at least.

and if the universe (multiverse) is infinite, then there are quite a lot of experiments to be done... :-D
