In one of its most urgent folds, Catherine Keller's Cloud of the Impossible juxtaposes negative theology with relational theology for the sake of thinking constructively about today's global climate of religious conflict and ecological upheaval. The tension between these two theological approaches reflects her desire to unsay past harmful theological speech but also to speak into the present silences about the possibility of a future that is not only to be feared. Suffusing Keller's Cloud is the related possibility of living (...) out one's life in conversation with a religious tradition having accepted the nonknowing character of its wisdom. Here, I develop the notion of “hypothetical faith” as an epistemic posture that commits itself to some particular religious tradition even as it acknowledges the unverifiability of that tradition's deepest truths. Understood as operating at the opposite end of the testability spectrum from science, religion-as-hypothesis provides a way of saying and unsaying one's tradition at the same time. (shrink)

Freely falling point-like objects converge toward the center of the Earth. Hence the gravitational field of the Earth is inhomogeneous, and possesses a tidal component. The free fall of an extended quantum mechanical object such as a hydrogen atom prepared in a high principal-quantum-number state, i.e. a circular Rydberg atom, is predicted to fall more slowly than a classical point-like object, when both objects are dropped from the same height above the Earth’s surface. This indicates that, apart from transitions between (...) quantum states, the atom exhibits a kind of quantum mechanical incompressibility during free fall in inhomogeneous, tidal gravitational fields like those of the Earth.A superconducting ring-like system with a persistent current circulating around it behaves like the circular Rydberg atom during free fall. Like the electronic wavefunction of the freely falling atom, the Cooper-pair wavefunction is quantum mechanically incompressible. The ions in the lattice of the superconductor, however, are not incompressible, since they do not possess a globally coherent quantum phase. The resulting difference during free fall in the response of the nonlocalizable Cooper pairs of electrons and the localizable ions to inhomogeneous gravitational fields is predicted to lead to a charge separation effect, which in turn leads to a large Coulomb force that opposes the convergence caused by the tidal gravitational force on the superconducting system.A “Cavendish-like” experiment is proposed for observing the charge separation effect induced by inhomogeneous gravitational fields in a superconducting circuit. The charge separation effect is determined to be limited by a pair-breaking process that occurs when low frequency gravitational perturbations are present. (shrink)
