Problem
Someone argues: 'MICROSCOPE bounds the Eotvos parameter at ∣ε(Ti,Pt)∣≲2.7×10−15. By Schiff's conjecture, universality of free fall at this level implies that local Lorentz invariance and local position invariance also hold to the same 2.7×10−15 precision. The three pillars together make up the strong equivalence principle, so MICROSCOPE has verified the strong equivalence principle to a few parts in 1015, and with it, confirmed that Einstein's theory is the one true theory of gravity.' Find the errors in this argument and give a corrected statement of what MICROSCOPE establishes.
