Generalized De Sitter Space
Pedro F. Gonzalez-Diaz
This paper deals with some two-parameter solutions to the spherically symmetric, vacuum Einstein equations which, we argue, are more general than de Sitter solution. The global str…
On the warp drive space-time
Pedro F. Gonzalez-Diaz
In this paper the problem of the quantum stability of the two-dimensional warp drive spacetime moving with an apparent faster than light velocity is considered. We regard as a maxi…
Nonorientable spacetime tunneling
Pedro F. Gonzalez-Diaz, Luis J. Garay
Misner space is generalized to have the nonorientable topology of a Klein bottle, and it is shown that in a classical spacetime with multiply connected space slices having such a t…
Perdurance of multiply connected de Sitter space
Pedro F. Gonzalez-Diaz
This paper deals with a study of the effects that spherically symmetric first-order metric perturbations and vacuum quantum fluctuations have on the stability of the multiply conne…
