Novel particle beam could challenge Einstein's theory of gravity

A team led by Professor Anna Soter from ETH Zurich and the Paul Scherrer Institute (PSI) in Villigen has taken a step toward an experiment to measure muon gravitational interaction. The goal is to test whether gravity acts equally on ordinary and exotic matter, potentially challenging Einstein's theory of gravity.
