A nanonewton force facility to test Newton's law of gravity at micro- and submicrometer distances

摘要

An experiment to test Newton's law of gravity at micro- and submicrometer distances using a nanonewton force facility at PTB and modern microtechnologies is proposed. It is anticipated that the proposed method can advance the search for non-Newtonian gravity forces via an enhanced sensitivity of 103 to 104 in comparison to current experiments at the micrometer length scale.
