Problem
Someone argues: 'MICROSCOPE (2022) reported ε(Ti,Pt)=[−1.5±2.3(stat)±1.5(syst)]×10−15. Einstein's General Relativity predicts ε=0 exactly. The measured value is consistent with zero, so the experiment has confirmed that General Relativity is the correct theory of gravity, and has ruled out every alternative theory.' Find the error, or errors, in this argument, and state what MICROSCOPE's result does and does not establish.
