1 | The main text of this paper is a minimally corrected version of the previously unpublished arXiv submission [1],
in which the original proposal that the final state of complete gravitational collapse is a non-singular gravitational vacuum
condensate star (‘gravastar’) was made. A somewhat expanded version of this paper appeared in [2].
The authors take this opportunity to provide an extended Appendix A, updating the status of the gravastar proposal, collecting
under seven subtitles the most significant developments over the past two decades relating to this proposal, with additional
explanation and annotations for each. |
