Non-spherical rapid acceleration of mass (or energy) to a relativistic velocity is natural source gravitational radiation. Such conditions arise in both long and short gamma-ray bursts whose central engine ejects jets. The resulting wave signal memory type, rising finite level (of order 4 G E/r) over duration that corresponds the longer either injection time jet. We explore properties such sign...

One of the conceptual tensions between quantum mechanics (QM) and general relativity (GR) arises from the clash between the spatial nonseparability of entangled states in QM, and the complete spatial separability of all physical systems in GR, i.e., between the nonlocality implied by the superposition principle, and the locality implied by the equivalence principle. Experimental consequences of...
