A cartoon illustrates results from the MICROSCOPE satellite mission, which has measured with astronomical sensitivity the falling rate of different objects under gravity.
Measuring gravitational analogues of quantum phenomena could lead to high-precision measurement of gravitational forces, according to a theoretical proposal. Read More »
