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.
