Exploring the Foundations of the Universe with Space Tests of the Equivalence Principle

We present the scientific motivation for future space tests of the equivalence principle, and in particular the universality of free fall, at the \(10^{-17}\) level or better. Two possible mission scenarios, one based on quantum technologies, the other on electrostatic accelerometers, that could rea...

Zusammenfassung:	We present the scientific motivation for future space tests of the equivalence principle, and in particular the universality of free fall, at the \(10^{-17}\) level or better. Two possible mission scenarios, one based on quantum technologies, the other on electrostatic accelerometers, that could reach that goal are briefly discussed.
