A direct probe of dark energy interactions with a solar System laboratory

Metadata Updated: July 17, 2020

We propose a mission concept for direct detection of dark energy interactions with normal matter in a Solar System laboratory. Dark energy is the leading proposal to answer the question of the accelerated expansion of the Universe. This interaction must be highly suppressed to be consistent with the gravity measurements and observations we have so far, but can be probed with specifically designed experiments. By flying unscreened atomic particles through special gravitational field regions in the Solar System and conducting double differential measurements to isolate possible dark energy interaction with the atoms, we will stand a chance to achieve a direction detection of dark energy, akin to direct detection of dark matter and gravitational waves. This could lead to a fundamental shift in our understanding of fundamental physics and our universe, stimulating a wide variety of foundational research in cosmology and particle physics.
