MICROSCOPE's view at gravitation

Bergé, Joel

The weak equivalence principle (WEP) is the cornerstone of general relativity (GR). Testing it is thus a natural way to confront GR to experiments, which has been pursued for four centuries with increasing precision. MICROSCOPE is a space mission designed to test the WEP with a precision of 1 in 10¹⁵ parts, two orders of magnitude bette…
