Gravitational instability of exotic compact objects

Exotic compact objects with physical surfaces a Planckian distance away from where the horizon would have been are inspired by quantum gravity. Most of these objects are defined by a classical spacetime metric, such as boson stars, gravastars and wormhole

与视界原本所在位置相距普朗克长度的具有物理表面的奇异致密天体是受到量子引力启发而提出的。这些天体大多由经典的时空度规来定义，比如玻色子星、引力真空星和虫洞。
