The Sound of Clearing the Throat: Gravitational Waves from a Black Hole Orbiting in a Wormhole Geometry
James B. Dent, William E. Gabella, Kelly Holley-Bockelmann +1
Current ground-based gravitational wave detectors are tuned to capture the collision of compact objects such as stellar origin black holes and neutron stars; over 20 such events ha…
Stability Aspects of Wormholes in Gravity
James B. Dent, Damien A. Easson, Thomas W. Kephart +1
We study radial perturbations of a wormhole in gravity to determine regions of stability. We also investigate massive and massless particle orbits and tidal forces in this sp…
Covariantizing the interaction between dark energy and dark matter
Valerio Faraoni, James B. Dent, Emmanuel N. Saridakis
Coupling dark energy and dark matter through an effective fluid description is a very common procedure in cosmology, however it always remains in comoving coordinates in the specia…
Late Time Decay of the False Vacuum, Measurement, and Quantum Cosmology
Lawrence M. Krauss, James Dent, Glenn D. Starkman
The recent suggestion that late time quantum dynamics may be important for resolving cosmological issues associated with our observed universe requires a consideration of several s…
Closed timelike curves in asymmetrically warped brane universes
Heinrich Päs, Sandip Pakvasa, James Dent +1
In asymmetrically warped spacetimes different warp factors are assigned to space and to time. We discuss causality properties of these warped brane universes and argue that scenari…
