By going into space like Gravity Probe B, STEP could dramatically improve the precision of equivalence principle measurements. (discovermagazine.com)
The equations utilised to solve the problem are based on the physicists» basic knowledge, such as the definition of an event horizon and the so - called equivalence principle, which is part of the foundation of Einstein's theory of gravity. (sciencedaily.com)
In this way, the researchers expect to test whether the strong equivalence principle holds. (discovermagazine.com)
