Does the Notion of Gravastar Make Sense in the TGD Framework?
Abstract
Gravastar provides an alternative view of blackhole-like objects. The density is constant inside the gravastar and there is no singularity at the origin. Interior has de-Sitter metric having constant density of dark energy with rho = -p. The surface contains a layer of exotic matter moving with light velocity and having rho = p. The exterior has Scwartschild metric. It came as a surprise that the TGD based model of blackhole-like objects and perhaps even of stars could be modelled as gravastars.
