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…
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…
