The disinformation problem for black holes (pop version)
Sean A. Hayward
The supposed information paradox for black holes is based on the fundamental misunderstanding that black holes are usefully defined by event horizons. Understood in terms of locall…
The disinformation problem for black holes (conference version)
Sean A. Hayward
Basic properties of black holes are explained in terms of trapping horizons. It is shown that matter and information will escape from an evaporating black hole. A general scenario…
The light cone at infinity
Sean A. Hayward
A recent refinement of Penrose's conformal framework for asymptotically flat space-times is summarized. The key idea concerns advanced and retarded conformal factors, which allow a…
Recent progress in wormhole dynamics
Sean A. Hayward
Space-time wormholes were introduced in Wheeler's idea of space-time foam. Traversible wormholes as defined by Morris & Thorne became popular as potential short cuts across the uni…
Black holes and traversible wormholes: a synthesis
Sean A. Hayward
A unified framework for black holes and traversible wormholes is described, where both are locally defined by outer trapping horizons, two-way traversible for wormholes and one-way…
Gravitational radiation, energy and reaction on quasi-spherical black holes
Sean A. Hayward
Gravitational radiation is locally defined where the wavefronts are roughly spherical. A local energy tensor is defined for the gravitational radiation. Including this energy tenso…
