Final Results of the MICROSCOPE Mission Confirms Einstein's Equivalence Principle

Long-time Slashdot reader orsayman writes: Remember the MICROSCOPE satellite ? In 2017, based on its first results, scientists were able to confirm Einstein's equivalence principle (a key assumption in General Relativity) to unprecedented precision. Recently, they were able to improve precision by almost another order of magnitude by using all the data. Fortunately (or not) no violation of the principle was detected which could help physicists to improve their theories of quantum gravity. Apparently the team expects to send a new mission "in the second half of the 2030s" aiming for another huge improvement in precision.
