Does a superconductor shield gravity?
Abstract
Recently there were some experimental observations which were interpreted as due to a shielding of the gravitational interaction by a superconducting disc in a static configuration as well as when set in rotation. We examine the experiments in detail and point out some difficulties which should be eliminated before reliable results can be claimed. The data from these experiments provide an internal check on the correctness of the hypothesis and we argue that the observed results are inconsistent with the hypothesis of shielding and therefore they are not shielding of the Earth's gravity. Our preliminary experiments in the static case do not show any evidence for the reported shielding.
