Journal ArticleDOI
Evading the Trans-Planckian problem with Vaidya spacetimes
TL;DR: In this paper, a purely kinematical model for evaporation based on two Vaidya spacetimes (outer and inner) joined across a thin time-like boundary layer was proposed.
Journal ArticleDOI
Cosmological milestones and energy conditions
Celine Cattoen,Matt Visser +1 more
TL;DR: In this paper, a catalogue of cosmological milestones, both at the kinematical and dynamical level, is presented, with a focus on non-singular singularities such as "bounces" and "turnarounds".
Journal ArticleDOI
Any spacetime has a Bianchi type I spacetime as a limit
Bethan Cropp,Matt Visser +1 more
TL;DR: In this article, it was shown that the immediate tube-like neighborhood of a geodesic can be blown up to yield a general Bianchi-type I spacetime, which shares some (but not all) of the features of the Penrose limit.
Journal ArticleDOI
Near-horizon geodesics for astrophysical and idealised black holes: Coordinate velocity and coordinate acceleration
TL;DR: In this article, the relative merits of horizon-penetrating versus horizon-non-paring coordinates were explored for both astrophysical and idealised black holes in the near-horizon limit, where an inappropriate choice of coordinates can quite easily lead to significant confusion.
Journal ArticleDOI
Hawking-Ellis type III spacetime geometry
Prado Martín-Moruno,Matt Visser +1 more
TL;DR: In this article, a Lagrangian model leading to type III stress energy tensors is presented. But the Lagrangians are not suitable for the type III tensor. And they are incompatible with either planar or spherical symmetry, so one should look at spacetimes of low symmetry (or no symmetry).
