Global Causal Structure of a Transient Black Object
Tehani K. Finch, James Lindesay
A singularity-free and spherically symmetric transient black object whose center remains always timelike, yet directly manifests a trapped region, has been constructed and numerica…
Self-consistent solutions of canonical proper self-gravitating quantum systems
James Lindesay
Generic self-gravitating quantum solutions that are not critically dependent on the specifics of microscopic interactions are presented. The solutions incorporate curvature effects…
Penrose Diagram for a Transient Black Hole
James Lindesay, Paul Sheldon
A Penrose diagram is constructed for a spatially coherent black hole that smoothly begins an accretion, then excretes symmetrically as measured by a distant observer, with the init…
Quantum Behaviors and Dynamic Horizons
James Lindesay
Geometries with horizons offer insights into relationships between general relativity and quantum physics. Quantum mechanics constrains relationships between kinematic parameters a…
Causal Structures of Dynamic Black Holes
Beth A. Brown, James Lindesay
Dynamic space-times, especially those manifesting horizons, provide useful laboratories for examining how macroscopic quantum behaviors consistently co-generate gravitational pheno…
Global Structure of a Multi-Fluid Cosmology
James Lindesay
Fluid cosmologies are consistent with the generally accepted observational evidence during intermediate and late times, and they need not have singular behavior in primordial times…
Construction of a Penrose Diagram for an Accreting Black Hole
Beth A. Brown, James Lindesay
A Penrose diagram is constructed for a spatially coherent black hole that accretes at stepwise steady rates as measured by a distant observer from an initial state described by a m…
Quantum Behaviors on an Excreting Black Hole
James Lindesay
Often, geometries with horizons offer insights into the intricate relationships between general relativity and quantum physics. However, some subtle aspects of gravitating quantum…
An Exploration of the Physics of Spherically Symmetric Dynamic Horizons
James Lindesay
Geometries with horizons offer insights into relationships between general relativity and quantum physics. For static spherically symmetric space-times, the event horizon is coinci…
Radial Photon Trajectories Near an Evaporating Black Hole
Beth A. Brown, James Lindesay
The radial motion of photons emitted near the horizon of a black hole that evaporates at a steady rate is examined. The space-time of the black hole is generated using non-orthogon…
Construction of a Penrose Diagram for a Spatially Coherent Evaporating Black Hole
Beth A. Brown, James Lindesay
A Penrose diagram is constructed for an example black hole that evaporates at a steady rate as measured by a distant observer, until the mass vanishes, yielding a final state Minko…
Insights into the Evolution of Horizons from Non-Orthogonal Temporal Coordinates
James Lindesay
The introduction of coordinates representing the points of view of various observers results in the possibility of horizons when acceleration and gravitation are included. A horizo…
Coordinates with Non-Singular Curvature for a Time Dependent Black Hole Horizon
James Lindesay
A naive introduction of a dependency of the mass of a black hole on the Schwarzschild time coordinate results in singular behavior of curvature invariants at the horizon, violating…
Diagonal Forms of a Dual Scale Cosmology
James Lindesay
A hybrid metric with off-diagonal temporal-radial behavior that was constructed to conveniently parameterized the early and late time behaviors of the universe is shown to have dia…
Thermal Evolution of a Dual Scale Cosmology
James Lindesay
Previous work developed a space-time metric with two cosmological scales; one that conveniently describes the classical evolution of the dynamics, and the other describing a scale…
An Introduction of Multiple Scales in a Dynamical Cosmology
James Lindesay
The discovery of scale acceleration evidenced from supernovae luminosities and spatial flatness of feature evolution in the cosmic microwave background presents a challenge to the…
