摘要: Einstein’s Weak Equivalence Principle (WEP) states that gravitational mass is identical to inertial mass. This hypothesis has withstood experimental tests an impressive accuracy of one part in hundred billion. Various hypotheses based on theory and observations with matter suggest violations WEP for antimatter may exist anywhere from the per million 200% level. An observed violation at any level would have a profound impact, e.g. it offer explanation why are so distinctly separated Cosmos. We propose precise test antiprotons microgravity. expect about million, foresee additional advancements several orders magnitude precision could follow further technical developments.
