Abstract
Recent advances in optical atomic clocks and optical time transfer have enabled new possibilities in precision metrology for both tests of fundamental physics and timing applications. Space offers both the potential to vary significantly the gravitational potential in which experiments operate and a microgravity environment free from local earth fluctuations. As a result, space borne optical clock tests of fundamental physics could achieve sensitivities four (or more) orders of magnitude beyond those of current tests of relativity. Additional fundamental test opportunities include enhanced searches for dark matter and drifts in fundamental constants.Citation
